Show Notes:

Bringing an Abandoned Satellite Back to Life and Use

  • An independent team of engineers recovering old imagery on magnetic tape reels from the first lunar orbiter missions decided to accomplish a landmark achievement: to turn on, command and maneuver a NASA spacecraft long ago abandoned
  • Original mission : Sun/Earth Explorer 3 (ISEE-3)
  • Originally the mission was cooperative effort between NASA and ESRO/ESA to study the interaction between the Earth’s magnetic field and the solar wind.
  • Examine in detail the structure of the solar wind near the Earth and the shock wave that forms the interface between the solar wind and Earth\’s magnetosphere
  • Investigate motions of and mechanisms operating in the plasma sheets, and continue the investigation of cosmic rays and solar flare emissions in the interplanetary region near 1 AU
  • Second mission: International Cometary Explorer
  • On June 10, 1982, after completing its original mission, ISEE-3 was repurposed. It was renamed the International Cometary Explorer (ICE)
  • The primary scientific objective of ICE was to study the interaction between the solar wind and a cometary atmosphere
  • ICE carried no cameras. It instead carried instruments for measurements of energetic particles, waves, plasmas, and fields
  • It was sent on a trajectory intercepting that of Comet Giacobini-Zinner and on 11 September 1985, the craft passed through the plasma tail of Comet Giacobini-Zinner
  • It transited between the Sun and Comet Halley in late March 1986, when other spacecraft were in the vicinity of Comet Halley, ICE flew through the tail
  • Heliospheric mission
  • This phase of the mission was approved by NASA in 1991, which consisted of investigations of coronal mass ejections in coordination with ground-based observations
  • End of mission
  • On May 5, 1997, NASA ended the ICE mission, and ordered the probe shut down, with only a carrier signal left operating
  • Further contact
  • In 1999, NASA made brief contact with ICE to verify its carrier signal and discovered that it had not been powered off after the last contact
  • On September 18, 2008 a status check revealed that all but one of its 13 experiments were still functioning, and it still has enough propellant
  • Bringing It Back to Life?
  • Earlier in 2014, officials with the Goddard Space Flight Center had said that the Deep Space Network equipment necessary to transmit signals to the spacecraft had been decommissioned in 1999, and that replacing it was not economically feasible
  • An independent team of engineers recovering old imagery on magnetic tape reels from the first lunar orbiter missions decided to accomplish a landmark achievement: to turn on, command and maneuver a NASA spacecraft long ago abandoned
  • They began to study the feasibility and challenges involved in reviving the \’dead\’ satellite
  • A team webpage said, \”We intend to contact the ISEE-3 (International Sun-Earth Explorer) spacecraft, command it to fire its engine and enter an orbit near Earth, and then resume its original mission…If we are successful we intend to facilitate the sharing and interpretation of all of the new data ISEE-3 sends back via crowdsourcing.\”
  • Crowdsourcing
  • To cover the costs of writing the software to communicate with the probe, searching through the NASA archives for the information needed to control the spacecraft, and buying time on the dish antennas
  • On May 15, 2014, the project reached its crowdfunding goal, and they further met a \’stretch\’ goal of $150,000
  • Window of Opportunity
  • The team needed to contact the spacecraft before the end of May because the next close approach to the Earth won’t be until 30-40 years
  • The ISEE-3/ICE spacecraft was never really designed to be an interplanetary cruiser and thus the thrusters on board are very small
  • The project members are working on deadline: if they get the spacecraft to change its orbit by late May or early June 2014, it can use the Moon\’s gravity to get back into a useful halo orbit.
  • The team estimates that if they wait until mid-June to do the course correction that it will take 17 hours of thrusting to get the course change of about 40 meters/second that they will need at that time
  • Hardware and Software
  • It has been 30 years since the original project was started and and documents and magnetic tapes have disappeared.
  • The software and hardware to program, command and transmit to ISEE-3 are long gone
  • Amateur radio operators now have technology sufficient to acquire the signal and through the internet are also a part of the recovery effort
  • Even without the original hardware transmitter, today’s high-speed electronics are able to emulate in software the hardware from 36 years ago
  • Project members obtained the needed hardware (power amplifier, modulator/demodulator and installed it on the 305-meter Arecibo dish antenna on May 19, 2014
  • Technical Progress
  • This is an ongoing process and the team has dug some of the pertinent information out of 35 year old IEEE or AIAA papers that are publicly available
  • Most of the best information the team found was from the people who worked on the project in the 1980\’s when the spacecraft was fully operational
  • They also obtained several documents from NASA as part of the development of thier Space Act Agreement
  • Since there is no computer on board the ISEE-3 spacecraft the task is actually much easier since we are going to be directly commanding various subsystems
  • Non-Reimbursable Space Act Agreement
  • Although NASA is not funding the project, it made advisors available and gave approval to try to establish contact
  • On May 21, 2014, NASA announced that it had signed a Non-Reimbursable Space Act Agreement with the ISEE-3 Reboot Project
  • \”This is the first time NASA has worked such an agreement for use of a spacecraft the agency is no longer using or ever planned to use again,\” officials said

Distracted by Classroom Decorations?

  • New research from Carnegie Mellon University shows that too much materials covering a classroom wall may end up disrupting attention and learning in young children
  • The Low Down
  • Researchers looked at whether classroom displays affected children\’s ability to maintain focus during instruction and to learn the lesson content
  • They found that children in highly decorated classrooms were more distracted, spent more time off-task and demonstrated smaller learning gains than when the decorations were removed
  • The Study
  • 24 kindergarten students were placed in laboratory classrooms for six introductory science lessons on topics they were unfamiliar with
  • Three lessons were taught in a heavily decorated classroom, and three lessons were given in a sparse classroom.
  • Results
  • The results showed that while children learned in both classroom types, they learned more when the room was not heavily decorated
  • Children\’s accuracy on the test questions was higher in the sparse classroom (55 percent correct) than in the decorated classroom (42 percent correct).
  • When the researchers tallied all of the time children spent off-task in both types of classrooms, the rate of off-task behavior was higher in the decorated classroom (38.6 percent time spent off-task) than in the sparse classroom (28.4 percent time spent off-task)
  • The Future
  • The researchers are interested in finding out if the visual displays were removed, whether the children\’s attention would shift to another distraction
  • Additional research is needed to know what effect the classroom visual environment has on children\’s attention and learning in real classrooms
  • They say that they do not suggest by any means that this is the answer to all educational problems but that teachers should consider whether some of their visual displays may be distracting

Flying With Only A Thought

  • Scientists have now demonstrated the feasibility of flying via brain control, with astonishing accuracy
  • First Breakthrough
  • Seven subjects took part in the flight simulator tests
  • They had varying levels of flight experience, including one person without any practical cockpit experience whatsoever
  • The accuracy with which the test subjects stayed on course by merely thinking commands would have sufficed, in part, to fulfill the requirements of a flying license test
  • Several of the subjects also managed the landing approach under poor visibility
  • In The Future
  • Scientists are now focusing in particular on the question of how the requirements for the control system and flight dynamics need to be altered to accommodate the new control method
  • Normally, pilots feel resistance in steering and must exert significant force when the loads induced on the aircraft become too large
  • This feedback is missing when using brain control
  • The researchers are thus looking for alternative methods of feedback to signal when the envelope is pushed too hard, for example

Jupiter\’s Great Red Spot Shrinking?

  • Twitter | Michael Thalleen ‏@ThalleenM
  • Jupiter\’s Great Red Spot Shrinks to Smallest Size Ever Seen
  • The Great Red Spot
  • “Recent Hubble Space Telescope observations confirm that the spot is now just under 10,250 miles (16,500 km) across, the smallest diameter we’ve ever measured,” said Amy Simon of NASA’s Goddard Space Flight Center
  • Using historic sketches and photos from the late 1800s, astronomers determined the spot’s diameter then at 25,475 miles (41,000 km) across
  • Changes
  • Starting in 2012 amateur observations revealed a noticeable increase in the spot’s shrinkage rate
  • They showed that the spot’s “waistline” is getting smaller by just under 620 miles (1,000 km) per year while its north-south extent has changed little
  • This has caused the spot to become more circular in shape
  • Cause
  • There are no firm answers yet as to what is causing the drastic downsizing,
  • New observations however show that very small eddies are feeding into the storm which may be responsible for the accelerated change by altering the internal dynamics of the Great Red Spot
  • The storm appears to be conserving angular momentum by spinning faster the same way an ice skater spins up when they pulls in their arms
  • The faster winds might also help shrink the spot further or bring about its rejuvenation.

— CURIOSITY UPDATE —

  • The Image from Mars Hand Lens Imager (MAHLI)
  • Shows the rock target \”Windjana\” and its immediate surroundings after inspection of the site by the rover
  • The researchers drilled a test hole and a sample collection hole produced the mounds of drill cuttings that are markedly less red than the other visible surfaces
  • This preparatory \”mini drill\” hole, to lower right from the open hole, was drilled on Sol 615 (April 29, 2014) and subsequently filled in with cuttings from the sample collection drilling.
  • The open hole from sample collection is 0.63 inch (1.6 centimeters) in diameter. It was drilled on Sol 621 (May 5, 2014).
  • The vigorous activity of penetrating the rock with the rover\’s hammering drill also resulted in slides of loose material near the rock
  • Gathering Samples
  • Since then, the 1 ton robot carefully scrutinized the resulting 2.6 inches (6.5 centimeters) deep borehole, the scientists then hit the fresh bore hole with a pinpoint series of parting laser blasts
  • The mound of dark grey colored drill tailings, much darker and greyer that the exterior of the rock, that are piled around for an up close examination of the texture and composition with the MAHLI camera and spectrometers
  • The team has successfully delivered pulverized and sieved samples to the pair of onboard miniaturized chemistry labs [Chemistry and Mineralogy instrument (CheMin) and Sample Analysis at Mars instrument (SAM)] for chemical and compositional analysis.
  • Researchers decided that one drill campaign into Kimberley was enough, so the rover will not be drilling into any other rock targets at this location
  • There will be further analysis of the ‘Windjana’ sample along the way since there’s plenty of leftover sample material stored in the CHIMRA sample processing mechanism to allow future delivery of samples when the rover periodically pauses during driving.
  • The Future
  • It may be a very long time before the next drilling when the rover arrives at the foothills of Mount Sharp
  • The current location, Windjama, lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay
  • It still has about another 4 kilometers to go to reach the foothills of Mount Sharp sometime later this year

SCIENCE CALENDAR

Looking back

  • May 29, 1919 : 95 years ago : Einstein\’s Relativity Theory Proved : A solar eclipse permitted observation of the bending of starlight passing through the sun\’s gravitational field, as predicted by Albert Einstein\’s theory of relativity. Separate expeditions of the Royal Astronomical Society travelled to Brazil and off the west coast of Africa. Both made measurements of the position of stars visible close to the sun during a solar eclipse. These observations showed that, indeed, the light of stars was bent as it passed through the gravitational field of the sun. This was a key prediction of Albert Einstein\’s theory that gravity affected energy as in addition to the familiar effect on matter. The verification of predictions of Einstein\’s theory, proved during the solar eclipse was a dramatic landmark scientific event.

2nd Infant Possibly Cured of HIV

  • A second American baby born with the AIDS virus may have had her infection put into remission and possibly cured by very early treatment, in this instance, four hours after birth.
  • Last Time on SciByte …
  • Scibyte 84 | HIV & SpaceX Troubles | March 5, 2013
  • The \’First Case\’
  • The girl was born in LA a month after researchers announced the first case in Mississippi last year that led doctors worldwide to rethink how fast and hard to treat infants born with HIV
  • The Mississippi baby is now 3 1/2 and seems HIV-free despite no treatment for about two years although she is still getting AIDS medicines, so the status of her infection is not as clear.
  • Treatment
  • Most HIV-infected moms in the U.S. get AIDS medicines during pregnancy, which greatly cuts the chances they will pass the virus to their babies
  • The LA baby was born mother was not taking her HIV medicines although the mom was given AIDS drugs during labor to try to prevent transmission of the virus
  • Doctors started the baby on AIDS drugs within a few hours after birth before test results came back, tests later confirmed she had been infected
  • The infant remained on antivirals until 18 months of age, at which point the child was lost to follow-up for a while
  • Ten months after discontinuation of treatment, the child underwent repeated standard blood tests, none of which detected HIV presence in the blood
  • Tests
  • A host of sophisticated tests at multiple times suggest the LA baby has completely cleared the virus
  • Doctors are cautious about suggesting she has been cured, instead of being in remission but it looks like a cure
  • The baby\’s signs are different from what doctors see in patients whose infections are merely suppressed by successful treatment
  • Adult AIDS-related Development
  • Only about 1 percent of people have two copies of the gene that gives this protection
  • Scientists have modified genes in the blood cells of a dozen adults to help them resist HIV from a donor with natural immunity to the virus
  • HIV usually infects blood cells through a protein on their surface called CCR5. A California company, Sangamo BioSciences Inc., makes a treatment that can knock out a gene that makes CCR5.
  • They tested it in 12 HIV patients who had their blood filtered to remove some of their cells. The treated cells were infused back into the patients
  • Four weeks later, half of the patients were temporarily taken off AIDS medicines to see the gene therapy\’s effect
  • The virus returned in all but one of them; that patient turned out to have one copy of the protective gene
  • Researchers knew that the virus was going to come back in most of the patients, but the hope is that the modified cells eventually will outnumber the rest and give the patient a way to control viral levels without medicines

Tracking SeaTurtles

  • Small satellite-tracking devices attached to sea turtles swimming off Florida\’s coast have delivered first-of-its-kind data that could help unlock the mystery of what endangered turtles do during the \”lost years.\”
  • \”Lost Years
  • \”Lost years\” refers to the time after turtles hatch and head to sea where they remain for many years before returning to near-shore waters as large juveniles
  • The time period is often referred like this because not much has been known about where the young turtles go and how they interact with their oceanic environment
  • Before this study, most of the scientific information about the early life history of sea turtles was inferred through genetics studies, opportunistic sightings offshore, or laboratory-based studies
  • With real observations of turtles in their natural environment, scientists are able to examine and reevaluate existing hypotheses about the turtles\’ early life history
  • Tracking
  • A team of scientists tracked 17 loggerhead turtles for 27 to 220 days in the open ocean using small, solar-powered satellite tags
  • The goal was to better understand the turtles\’ movements, habitat preferences, and what role temperature may play in early sea turtle life history
  • While the turtles remain in oceanic waters (traveling between 124 miles to 2,672 miles) off the continental shelf and the loggerhead turtles sought the surface of the water as predicted
  • The Study
  • The study found that the turtles do not necessarily remain within the currents associated with the North Atlantic subtropical gyre
  • It was historically thought that loggerhead turtles hatching from Florida\’s east coast complete a long, developmental migration in a large circle around the Atlantic entrained in these currents
  • The team\’s data suggest that turtles may drop out of these currents into the middle of the Atlantic (Sargasso Sea)
  • The team also found that while the turtles mostly stayed at the sea surface, where they were exposed to the sun\’s energy, the turtles\’ shells registered more heat than anticipated (as recorded by sensors in the satellite tags
  • Hiding in the Seaweed
  • A new hypothesis about why the turtles seek refuge in seaweed (Sargassum). It is a type of seaweed found on the surface of the water in the deep ocean long associated with young sea turtles.
  • Scientists propose that young turtles remain at the sea surface to gain a thermal benefit, which makes sense because the turtles are cold blooded animals by remaining at the sea surface
  • By associating with Sargassum habitat, turtles gain a thermal refuge of sorts that may help enhance growth and feeding rates, among other physiological benefits.
  • The Importance
  • Findings are important because the loggerhead turtles along with other sea turtles are threatened or endangered species
  • Florida beaches are important to their survival because they provide important nesting grounds in North America, more than 80% along Florida\’s coast
  • There are other important nesting grounds and nursing areas for sea turtles in the western hemisphere found from as far north as Virginia to South America and the Caribbean.
  • There\’s a whole lot that happens during the Atlantic crossing that we knew nothing about and this work helps to redefine Atlantic loggerhead nursery grounds and early loggerhead habitat use

New European Dinosaur

  • A new dinosaur species found in Portugal may be the largest land predator discovered in Europe, as well as one of the largest carnivorous dinosaurs from the Jurassic
  • Torvosaurus Gurneyi
  • Scientists discovered bones belonging to this dinosaur north of Lisbon, they were originally believed to be a dinosaur species from North America
  • Closer comparison of the shin bone, upper jawbone, teeth, and partial tail vertebrae suggested a new species, Torvosaurus Gurneyi
  • The mouth bones have a different shape and structure, the number of teeth, as well as size and shape of the mouth, may differentiate the European and the American
  • It had blade-shaped teeth up to 10 cm long, which indicates it may have been at the top of the food chain in the Iberian Peninsula roughly 150 million years ago
  • Scientists estimate that the dinosaur could reach 10 meters long and weigh around 4 to 5 tons
  • With a skull of 115 cm, it would be one of the largest terrestrial carnivores at this era
  • An active predator that hunted other large dinosaurs, as evidenced by blade shape teeth up to 10 cm
  • Evidences of closely related dinosaurs suggest that this large predator may have already been covered with proto-feathers

New Antibiotic to Fight Drug-Resistant Bacteria

  • A team of researchers have discovered a new class of antibiotics to fight drug-resistant bacteria
  • Oxadiazoles, was discovered in silico (by computer) screening and has shown promise in the treatment of MRSA in mouse models of infection
  • Researchers screened 1.2 million compounds found that the oxadiazole inhibits a penicillin-binding protein
  • The oxadiazoles are also effective when taken orally, currently there is only one marketed antibiotic for MRSA that can be taken orally.

  • Continuing On
  • Engineers will now occasionally commanding Curiosity to drive backwards in a newly tested bid to minimize serious damage to the six 20 inch diameter wheels
  • Curiosity is well on the way to her next near term goal, which is a science waypoint, named Kimberly (formerly called KMS-9), which lies about half a mile ahead.
  • \”Kimberley,\” features ground with striations and is where researchers plan to suspend driving for a period of science investigations

SCIENCE CALENDAR

Looking back | March 13

  • 1781 : 233 years ago : Uranus : Sir William Herschel announced his discovery of Uranus, the first planet discovered with a telescope. At the time of discovery he labeled it as a comet, by 1783 he finally acknowledged it was a planet, and by 1787, he had also observed the Uranian satellites Titania and Oberon (11 Jan 1787), which were later given these names by his son, John Herschel.
  • 1930 : 84 years ago : Pluto : Clyde W. Tombaugh telegraphed the discovery of Pluto to the Harvard College Observatory. After nearly a year of searching, Tombaugh discovered a possible moving object on photographic plates taken on January 21, 23 and January 29 confirmed the movement and discovery of Pluto.

Looking up this week

  • Keep an eye out for …

Typing on Autopilot

  • A conclusion of a recent study conducted by a team of cognitive psychologists shows that when you are typing away at your computer, you don\’t know what your fingers are really doing
  • It found that skilled typists can\’t identify the positions of many of the keys on the QWERTY keyboard and that novice typists don\’t appear to learn key locations in the first place
  • The Study
  • The researchers recruited 100 university students and members from the surrounding community to participate in an experiment
  • The participants completed a short typing test, then they were shown a blank QWERTY keyboard and given 80 seconds to write the letters in the correct location
  • On average, they typed 72 words per minute, moving their fingers to the correct keys six times per second with 94 percent accuracy
  • By contrast, they could accurately place an average of only 15 letters on a blank keyboard.
  • What the Results Mean
  • The fact that the typists did so poorly at identifying the position of specific keys didn\’t come as a surprise
  • For more than a century, scientists have recognized the existence of automatism: the ability to perform actions without conscious thought or intention
  • Automatic behaviors of this type are surprisingly common, ranging from tying shoelaces to making coffee to factory assembly-line work to riding a bicycle and driving a car
  • What did come as a surprise, however, was evidence that conflicts with the basic theory of automatic learning which holds that it starts out as a conscious process and gradually becomes unconscious with repetition
  • Automating Actions
  • According to the widely held theory, when you perform a new task or the first time, you are conscious of each action and store the details in working memory, then as you repeat the task, it becomes increasingly automatic
  • This allows you to think about other things while you performing the task but your conscious recollection of the details gradually fades away
  • Researchers were surprised when they found evidence that the typists never appear to memorize the key positions, not even when they are first learning to type.
  • Evidence for this conclusion came from another experiment included in the study
  • The \”Sub-Set Study\”
  • The researchers recruited 24 typists who were skilled on the QWERTY keyboard and had them learn to type on a Dvorak keyboard, which places keys in different locations.
  • After the participants developed a reasonable proficiency with the alternative keyboard, they were asked to identify the placement of the keys on a blank Dvorak keyboard
  • On average, they could locate only 17 letters correctly, comparable to participants\’ performance with the QWERTY keyboard.
  • \’Memorizing\’ without Memorizing, One Theory
  • According to the researchers, the lack of explicit knowledge of the keyboard may be due to the fact that computers and keyboards have become so ubiquitous that students learn how to use them in an informal, trial-and-error fashion when they are very young

2011 Tohoku Earthquake

  • In March 2011, a devastating tsunami struck Japan\’s Tohoku region
  • Now, researchers have uncovered the cause of this tsunami, shedding light on what displaced the seafloor off the northeastern coast of Japan
  • The Study
  • Scientists underwent a 50-day expedition on the Japanese drilling vessel Chikyu
  • They then drilled three holes in the Japan Trench area in order to study the rupture zone of the 2011 earthquake
  • A fault in the ocean floor where two of Earth\’s major tectonic plates meet deep beneath the surface of the Pacific Ocean.
  • The Conventional View
  • Deep beneath the seafloor, where rocks are strong, movements of the plates can generate a lot of elastic rebound
  • Closer to the surface of the seafloor, where rocks are softer and less compressed, rebound effect was thought to taper off
  • The Tohoku Earthquake
  • The largest displacement of plates before the 2011 tsunami occurred in 1960 off the coast of Chile when a powerful earthquake displaced sea floor plates by an average of 20 meters
  • The Tohoku earthquake, in contrast, displaced its own plates by 30 to 50 meters.
  • The fault itself is very thin–less than five meters thick in the area sampled, making it the thinnest plate boundary on Earth.
  • In addition, clay deposits that fill the narrow fault are made of extremely fine sediment, which makes it extremely slippery
  • Looking to the Future
  • These findings don\’t just show researchers a bit more about the past; they also have implications for the future
  • Learning more about the 2011 tsunami and its causes is an important step for monitoring future events and could help researchers provide earlier warnings
  • Other subduction zones in the northwest Pacific where this type of clay is present–from Russia\’s Kamchatka peninsula to the Aleutian Islands–may also be capable of generating similar, huge earthquakes

Coloring Silk Worm Silk

  • How It’s Done Now
  • Coloring fabric normally uses enormous amounts of fresh water
  • The water gets contaminated with dangerous chemicals in the process, requiring costly treatment before factories can dump it back into waterways—or wreaking havoc when factory owners dodge cleanup rules
  • A New Idea
  • A team fed ordinary silkworms mulberry leaves that had been sprayed with fabric dyes.
  • Out of seven tested dyes, only one worked, producing a thread that reminded me of pink-dyed hair.
  • The worms themselves take on some color before they weave their silk cocoons. Their colorful diets did not affect their growth
  • Scientists are just starting to study this idea, however, it remains to be seen if it\’s commercially viable
  • In this experiment, the Indian team tested seven azo dyes, which are cheap and popular in the industry
  • The scientists found different dyes moved through silkworms\’ bodies differently. Some never made it into the worms\’ silk at all
  • Others colored the worms and their cocoons, but the color molecules settled mostly in the sticky protein the worms add to their cocoons
  • That sticky stuff gets washed away before the silk is turned into fabric
  • Only one dye, named \”direct acid fast red,\” showed up in the final, washed silk threads. By the time it made it there, it was a pleasant, light pink.

Bone Grafting

  • Scientists have now discovered a way to refine sea coral properties so that it is more compatible with natural bone.
  • One Biomaterial Problem
  • When biomaterials do not biodegrade, they can continuously cause problems
  • In extreme conditions, it is possible that the different mechanical properties of the artificial bone graft may cause a re-fracture or become a source for bacterial growth in infection
  • Finding Solutions
  • In order to get around this issue researchers decided to study the calcium carbonate found in the exoskeleton of sea coral and convert it into coralline hydroxyapatite (CHA)
  • They then refined the material to produce coralline hydroxyapatite/calcium carbonate (CHACC)
  • This CHACC composition contained 15 percent of CHA in a thin layer around the calcium carbonate
  • The strong, porous structure has made CHA commercially successful, but contained significantly improved bio-degrading properties to support natural bone healing.
  • Not Ready for Wide Use Quite Yet
  • There is a ways to go before the material can match the benefits of an autograft and can be used by the several million people worldwide that undergo bone grafting procedures each year
    +The development of the CHACC material could provide an important step toward creating a biodegradable material that could help patients in the future

China’s ‘Yutu’ Lunar Lander

  • China’s moon landing probe successfully entered lunar orbit on Friday, Dec. 6
  • China’s ‘Yutu’ lunar lander is riding piggyback atop the four legged landing probe
  • Chang’e 3 is due to make a powered descent to the Moon’s surface on Dec. 14, firing the landing thrusters at an altitude of 15 km (9 mi) for a soft landing in a preselected area called the Bay of Rainbows or Sinus Iridum region.
  • The Bay of Rainbows is a lava filled crater located in the upper left portion of the moon as seen from Earth. The Sea of Tranquility, where Apollo 11 landed is the mid-upper right. Moon Map | Wikipedia

— CURIOSITY UPDATE —

  • 100,000 ChemCam Laser Shots
  • Chemistry and Camera instrument (ChemCam) uses the infrared laser to excite material and analyzes the spectrum of light to identify elements in the target
  • As of the start of December, ChemCam has fired its laser on Mars more than 102,000 times, at more than 420 rock or soil targets, and has also returned more than 1,600 images taken by its remote micro-imager camera
  • Each pulse delivers more than a million watts of power for about five one-billionths of a second
  • The 100,000th shot was one of a series of 300 to investigate 10 locations on a rock called \”Ithaca\” in late October
  • The shots were at a distance of 13 feet, 3 inches (4.04 meters) from the laser and telescope on rover\’s mast
  • More Habitable Lake Information
  • Curiosity rover has discovered evidence that an ancient Martian lake had the right chemical ingredients that could have sustained microbial life
  • The shallow ancient lake may have been about 30 miles long by 3 miles wide (50 by 5 kilometers)
  • The research team estimates that the lake existed for at least tens of thousands of years, as recent as 3.7 Billion years ago, perhaps even longer on an off-and-on basis, even when the lake might have been dry, the groundwater\’s still there
  • It could have potentially supported a class of microbes called chemolithoautotrophs, which obtain energy by breaking down rocks and minerals
  • Here on Earth, chemolithoautotrophs are commonly found in habitats beyond the reach of sunlight, such as caves and hydrothermal vents on the ocean floor
  • Cold Lake
  • The lack of weathering on Gale Crater\’s rim suggests that the area was cold when the lake existed
  • It\’s possible that a layer of ice covered the lake on a permanent or occasional basis
  • Even with that it still is a entirely viable habitable environments for chemolithoautotrophs
  • Mission Shift
  • Researchers announced that they are shifting the missions focus from searching for habitable environments to searching for organic molecules – the building blocks of all life as we know it.
  • The team believes they have found a way to increase the chance of finding organics preserved in the sedimentary rock layers
  • This means that the mission is now dedicated to the search for that subset of habitable environments which also preserves organic carbon

Looking back

  • Dec 14, 1962 : 51 years ago : Mariner 2 Venus Mission : The U.S. space probe Mariner 2 approached within about 34,000 kilometers (21,600 miles) of Venus, transmitting first time information about this planet. Launched 27 Aug 1962 from Cape Canaveral, Florida, on an Atlas- Agenda rocket, the Mariner 2 was the world\’s first successful interplanetary spacecraft. It sent back new information about interplanetary space and the very hot, heavy, mostly carbon dioxide atmosphere. The temperature was found to be about 500 ºC (900 ºF). Also for the first time, the spacecraft\’s solar wind experiment measured the density, velocity, composition and variation over time of the solar wind. It discovered that Venus lacks a strong magnetic field and radiation belts. Contact was lost 3 Jan 1963.

Show Notes:

Coma patient auditory function

  • New research suggests a coma patient’s chances of surviving and waking up could be predicted by changes in the brain’s ability to discriminate sounds
  • The low down
  • Recovery from comas has been linked to auditory function before, but it wasn’t clear whether function depended on the time of assessment
  • Previous studies tested patients several days or weeks after comas set in, in this new study looks at the critical phase during the first 48 hours
  • At early stages, comatose brains can still distinguish between different sound patterns
  • This ability progresses over time can predict whether a coma patient will survive and ultimately awaken which is very promising tool for prognosis
  • Significance
  • The study was led by neuroscientist of the University of Lausanne in Switzerland who studied 30 coma patients who had experienced heart attacks that deprived their brains of oxygen
  • All the patients underwent therapeutic hypothermia, a standard treatment to minimize brain damage, in which their bodies were cooled to 33* Celsius for 24 hours
  • They then played sounds for the patients and recorded their brain activity using scalp electrodes
  • Once in hypothermic conditions during the first 24 hours of coma then again a day later at normal body temperature
  • The sounds were a series of pure tones interspersed with sounds of different pitch, duration or location
  • The brain signals revealed how well patients could discriminate the sounds, compared with five healthy subjects
  • All the patients whose discrimination improved by the second day of testing survived and awoke from their comas
  • Many of those whose sound discrimination deteriorated by the second day did not survive
  • These results suggests that residual auditory function itself does not predict recovery, rather it’s the progression of function over time that is predictive.
  • The study couldn’t distinguish whether auditory function initially was preserved due to the hypothermia treatment or was related merely to the early stage of coma
  • Scientists speculate that distracting neural jabber may have been reduced during the hypothermia, making it easier for the patients’ brains to separate sounds
  • Of Note
  • Scientists are now running a follow-up study with 120 coma patients and whether the results can be replicated in a bigger population
  • The tests could eventually give information about patients who will survive during the first two days of coma

Water on Mercury?!

  • The low down
  • There has been speculation about water ice on Mercury dates back more than 20 years
  • In 1991, Earth-bound astronomers fired radar signals to Mercury and received results showing there could be ice at both poles
  • The speculations were reinforced by 1999 measurements using the more powerful Arecibo Observatory microwave beam in Puerto Rico
  • Radar pictures beamed back to New Mexico’s Very Large Array showed white areas that researchers suspected was water ice.
  • Temperatures on Mercury can reach 800 F [427 C] around the north pole, in areas permanently shielded from the sun’s heat
  • Significance
  • Confirming decades of suspicion, a NASA spacecraft has spotted vast deposits of water ice on the planet closest to the sun
  • Although the laser is weak, about the strength of a flashlight, but just powerful enough to distinguish bright icy areas from the darker, surrounding Mercury regolith
  • Messenger’s neutron spectrometer spotted hydrogen, which is a large component of water ice. But the temperature profile unexpectedly showed that dark, volatile materials – consistent with climes in which organics survive – are mixing in with the ice
  • Organic materials are life’s ingredients, though they do not necessarily lead to life itself the presence of organics is also suspected on airless, distant worlds such as Pluto
  • Messenger spacecraft found a mix of frozen water and possible organic materials
  • There is evidence of big pockets of ice is visible from a latitude of 85 degrees north up to the pole and smaller deposits scattered as far away as 65 degrees north.
  • Researchers also believe the south pole has ice, but Messenger’s orbit has not allowed them to obtain extensive measurements of that region yet
  • Of Note
  • Is is suspected that Mercury’s water ice is coated with a 4-inch (10 centimeters) blanket of “thermally insulating material
  • In the near future NASA will direct Messenger’s observation toward that area in the coming months — when the angle of the sun allows — to get a better look
  • Messenger will spiral closer to the planet in 2014 and 2015 as it runs out of fuel

Subglacial Life

  • In one of the most remote lakes of Antarctica, nearly 65 feet beneath the icy surface, scientists have uncovered a community of bacteria
  • Last time on SciByte
  • SciByte 33 | Sub Glacial Lakes & Updates [February 14, 2012]
  • The low down
  • Lake Vida, the largest of several unique lakes found in the McMurdo Dry Valleys, contains no oxygen, is mostly frozen and possesses the highest nitrous oxide levels of any natural water body on Earth
  • At approximately six times saltier than seawater the average temperature is minus 8 degrees Fahrenheit
  • The brine harbors a surprisingly diverse and abundant variety of bacteria that survive without a current source of energy from the sun
  • Previous studies of Lake Vida dating back to 1996 indicate the brine and its inhabitants have been isolated from outside influences for more than 3,000 years.
  • Significance
  • Collaborators developed stringent protocols and specialized equipment for their 2005 and 2010 field campaigns to sample from the lake brine while avoiding contaminating the pristine ecosystem
  • To sample unique environments such as this, researchers must work under secure, sterile tents on the lake’s
    surface
  • The tents kept the site and equipment clean as researchers drilled ice cores, collected samples of the salty brine residing in the lake ice and assessed the chemical qualities of the water and its potential for harboring and sustaining life
  • Analyses suggest chemical reactions between the brine and the underlying iron-rich sediments generate nitrous oxide and molecular hydrogen which may provide the energy needed to support the brine’s diverse microbial life.
  • Additional research is underway to analyze the abiotic, chemical interactions between the Lake Vida brine and its sediment
  • Of Note
  • This finding expands our knowledge of environmental limits for life and how life can sustain itself in these extreme environments, it also helps define new niches of habitability
  • The best analog we have for possible ecosystems in the subsurface waters of Saturn’s moon Enceladus and Jupiter’s moon Europa

60-day Bread?!

  • The low down
  • Using microwave technology, one company says it can make bread last for two months
  • The claim
  • The claim is that it can preserve at least some of our food for longer, by zapping it with microwaves, with nuked bread can last up to 60 days
  • The equipment, which looks like a CT scanner for food, was originally developed to kill organisms like multi-resistant staph bacteria and salmonella
  • The developers realized it also kills bread mold in about a 10-second zap.
  • It works much like a home microwave, but the waves are produced in various frequencies, which allows for uniform heating
  • The same technology could also preserve fresh food like poultry, produce and more
  • Of Note
  • This technology is far more complex that microwaves that are commercially accessible.
  • Do not assume “nuking” you food in the microwave at home with make your bread last longer

– SPACECRAFT UPDATE –

Voyager 1, inch by inch

  • The low down
  • Data from two onboard instruments that measure charged particles showed the spacecraft first entered this magnetic highway region on July 28, 2012
  • Scientists refer to this new region as a magnetic highway for charged particles because our sun’s magnetic field lines are connected to interstellar magnetic field lines
  • They infer that this region is still inside our solar bubble because the direction of the magnetic field lines has not changed
  • The magnetic region is unlike it has been in before—about 10 times more intense than before the termination shock—but the magnetic field data show no indication we’re in interstellar space
  • The magnetic field data has turned out to be the key to pinpointing when Voyager 1 crossed the termination shock.

– CURIOSITY UPDATE –

  • Mission Notes
  • After several weeks of being stationary at the Rocknest site Curiosity began driving again on Sol 100
  • A significant milestone on the mission has now reached about a 0.3mi [0.5km] of total driving distance on the surface of Mars
  • The Curiosity team is now going to be moving to the East to a place called Point Lake while looking for a target to perform our first ever drill on Mars
  • Surface Radiation Levels
  • Average yearly dosage on Earth is .004 Sievert, Head CT scan is 0.002 Sv and a chest CT scan is 0.007 Sv
  • Astronauts aboard the International Space Station experience an average daily dose between 0.4 and 1.0 millisieverts
  • On it’s way to Mars its radiation data was around 1.9 millisieverts per day during the flight
  • Astronauts on the surface on Mars would receive an average dose of about 0.7 millisieverts per day
  • A mission consisting of a 180-day outbound cruise, a 600-day stay on Mars and another 180-day flight back to Earth would expose an astronaut to a total radiation dose of about 1.1 sieverts, unit of radiation
  • While 1 Sievert is 100 rem and I’ve seen numbers for CT scan from 0.01–0.06 sievert the ESA caps an astronauts lifetime exposure to 1 sievert
  • 1.1 Sv ~ 275 years on Earth ~ 4.8 years on the Space Station
  • Radiation Dose Chart | xkcd.com
  • My Hypotheses from Last Week
  • Surface Radiation Levels
  • Chace for organic compounds, most likely a simple hydrocarbon
  • Much less likely chance would be the announcement of nitrogen
  • The “de-Hype”
  • While many people had assumed that Curiosity had detected organic compounds in the Martian soil later statements said that’s it was not the case
  • Statements made mid to later last week stated that at this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics
  • Announcement
  • No final results have yet been released on the surface radiation levels
  • Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover
  • There is still no definitive detection of Martian organics at this point
  • SAM tentatively identified the oxygen and chlorine compound perchlorate
  • Perclorate is a reactive chemical previously found in arctic Martian soil by NASA’s Phoenix Lander
  • Perchlorates are the salts derived from perchloric acid and most are soluble in water
  • Natural perchlorate on Earth is in arid environments possibly from the oxidation of chlorine species involving ozone or its photochemical products
  • Reactions with other chemicals heated in SAM formed chlorinated methane compounds, one-carbon organics that were detected by the instrument
  • The chlorine is of Martian origin, but it is possible the carbon may be of Earth origin, carried by Curiosity and detected by SAM’s high sensitivity design
  • Analysis
  • While they are going to announce the final data for surface radiation levels that was not THE BIG announcement as I had thought
  • While the chlorine is of Martian origin, it is possible the carbon may be of Earth origin, carried by Curiosity and detected by SAM’s high sensitivity design

Looking back

  • Dec 11 1790 : 222 years ago : Aurora Borealis : the first recorded sighting of the Aurora Borealis took place in New England. The report said that a mysterious face seemed to appear in the atmosphere. It caused considerable alarm, as being regarded by many as a precursor of the last judgment. Most aurora borealis displays occur in September and October and again in March and April. The green, red, and frost-white light displays occur most frequently when there is a great deal of sunspot activity. “This evening, about eight o’clock there arose a bright and red light in the E.N.E. like the light which arises from a house on fire … which soon spread itself through the heavens from east to west, reaching about 43 or 44 degrees in height, and was equally broad.”

  • Measuring times
  • Time is measured in 1,000th of a second that has to be that close to both actual time and consistent
  • Races are started by electronic starter guns, with starting blocks that indicate when a runner reacts faster than humans can respond, making the runners re-start the race
  • More than 2,000 digital frames a second aid the timing system for the most accurate and precise system possible
  • For longer racing event with a lot of competitors RFID, Radio Frequency Identification, attached to shoes or bicycles allow accurate timing and tracking for each competitor
  • Technology
  • Some Long Jumpers utilize stereoscopic cameras, from BMW, to measure speed and angles of launch
  • Swimmers usitize fluid dynamic measurements so that they can train and compete in the most aerodynamic way as possible to
  • Runners can also use treadmill technology that provides support to minimize the weight of the athlete affecting the legs by creating a pressure bubble that can support part of the athletes weight
  • The Olympic pool utilize a number of different technologies to minimize waves including adjustable depth, gutters along the edges of the pool and lane lines
  • Mechanical engineers analyze top athletes to be able to both help athletes improve their technique and expand knowledge that could help provide information to be used for people with movement disorders, it can also used design more realistic and stronger robotic arms

Writing with your eyes



Credit: YouTube channel h2so4hurts | Credit: Lorenceau et al., Current Biology

  • The low down
  • People “locked in” by paralyzing disorders have long relied on blinks or facial twitches to build sentences one letter at a time
  • Jean Lorenceau of the Université Pierre et Marie Curie in Paris may have a new technology might allow people who have almost completely lost the ability to move their arms or legs to communicate freely
  • Significance
  • Eye-writing technology tricks the neuromuscular machinery into doing something that is usually impossible: to voluntarily produce smooth eye movements in arbitrary directions
  • Smooth pursuit, this eye motion is different from saccadic motion, in which we rapidly shift our eyes to, say, skim lines of text or scan a crowd
  • Smooth movements are normally impossible to control those movements smoothly in any direction
  • Lorenceau found by accident with another experiment that he was able to learn to do so.
  • To determine if other people could learn to do this he designed his own reverse-phi display with 200 disks that switch between black and white and are projected on a gray background.
  • When we see two images that are the photographic negatives (dark to light & light to dark) in rapid succession our brain sees the object in the image moving away from the negative image
  • This gives us the impression of motion when there is none
  • Over three 30-minute sessions, he was able to trained six volunteers
  • For the volunteers, who couldn’t see what they were writing, it was like writing with a pen that had run out of ink
  • Although some participants had a harder time of learning to control their eye movements than others by the end of the sessions most could freely draw legible letters and numbers
  • Of Note
  • This technology might also help to improve eye movement control in people with certain conditions such as dyslexia or ADHD and/or for experts, such as athletes or surgeons, whose activities strongly rely on eye movements
  • Now working on a better version of his eye writer, tests should start next year

Musical Variety

  • The low down
  • The Million Song Dataset is a freely-available collection of audio features and metadata for a million contemporary popular music tracks.
  • The songs come from nearly 45,000 artists with only 2,650 songs released between 1955 and 1959 and 177,808 songs released between 2005 and 2009.
  • Quantitative analysis for this study examined three aspects of those songs; timbre, pitch, and loudness of nearly half a million songs
  • Timbre accounts for the sound color, texture, or tone quality
  • Pitch roughly corresponds to the harmonic content of the piece, including its chords, melody, and tonal arrangements
  • Timbral variety peaked in the 1960’s and has been in steady decline to the present day and implies a homogenization of the overall timbral palette, which could point to less diversity in instrumentation and recording techniques
  • While it may be no surprise that music has gotten louder the same notes and chords that were popular in decades past are popular today
  • Musicians today seem to be less adventurous in moving from one chord or note to another, instead following the paths well-trod
  • Of Note
  • The Million Song Dataset, huge as it is, may not provide a representative slice of pop music, especially for old songs
  • The database draws on what’s popular now, as well as what has been digitized and made available for download
  • The older digitised music may not be the same that people enjoyed when those songs first came out.

Looking back

  • August 1, 1774 : 238 years ago : Oxygen : Joseph Priestley, British Presbyterian minister and chemist, identified a gas which he called “dephlogisticated air” – later known as oxygen. Priestley found that mercury heated in air became coated with “red rust of mercury,” which, when heated separately, was converted back to mercury with “air” given off. Studying this “air” given off, he observed that candles burned very brightly in it. Also, a mouse in a sealed vessel with it could breathe it much longer than ordinary air. A strong believer in the phlogiston theory, Priestley considered it to be “air from which the phlogiston had been removed.” Further experiments convinced him that ordinary air is one fifth dephlogisticated air, the rest considered by him to be phlogiston

Smart Headlight



YouTube Channel : LabEquipment

  • The low down
  • In rain and snow conditions headlights reflect off of the precipitation back to driver
  • Carnegie Mellon professor and his team are working on ‘smart’ headlights that can streamlight in between the drops
  • Significance
  • The system consists of a co-located imaging and illumination system– camera, projector, and beamsplitter
  • The camera uses a 5 ms exposure time and the system has a total latency of 13 ms when the system runs at 120Hz. with an operating range about 13 feet in front of the headlights
  • The camera images the precipitation at the top of the field of view, the processor can tell where the drops are headed and sends a signal to the headlights, headlights then make their adjustments and react to dis-illuminate the particles all in about about 13 ms.
  • Simulations
  • Computer simulations predict system effectiveness for different systems set ups during a heavy rainstorm [25 mm/hr] on a vehicle traveling 30 km/hr
  • Simulations show that a system operating near 1,000 Hz, with a total system latency of 1.5 ms, and exposure time of 1 ms can achieve 96.8% accuracy, with 90% light throughput expected
  • The system would still have a significant [>= 70%] visibility improvement at 400 Hz
  • A prototype system has already validated simulations on laboratory-generated rain operating at 120 Hz
  • Simulations show that it is possible to maintain light throughput well above 90 percent for various precipitation types
  • Of Note
  • The prototype consists of a camera with gigabit ethernet interface (Point Grey, Flea3), DLP projector (Viewsonic, PJD62531), and desktop computer with Intel architecture (Intel i7 quad core processor).
  • The team says that it may take three to four more years of development and “commercializing it as a product will take additional years.”

New mineral in old rock

  • The low down
  • A meteorite that fell in 1969 as an exploding fireball in the skies over Mexico, scattered thousands of pieces of meteorites across the state of Chihuahua
  • It is largest carbonaceous chondrite ever found on our planet and is considered by many the best-studied meteorite in history
  • Scientists have now discovered a new mineral embedded in that meteorite
  • Panguite is an especially exciting discovery since it is not only a new mineral, but also a material previously unknown to science
  • The mineral could be among the first solid objects formed in our solar system, dating back to over 4 billion years ago, before the formation of Earth and the other planets.

Extreme exoplanet discoveries



You Tube Channel pacargile | Credit: NASA; Frank Melchior

  • Kilodegree Extremely Little Telescope (KELT) North
  • – Telescope
  • Roughly as powerful as a high-end digital camera, making it slightly more diminutive than Kepler
  • KELT North scans the northern sky from Arizona
  • KELT South covers the southern sky from Cape Town, South Africa.
  • Rather than staring at a small group of stars at high resolution, the twin KELT North and KELT South telescopes observe millions of very bright stars at low resolution
  • The small ground-based KELT telescopes provide a low-cost alternative for exoplanet hunters by primarily using off-the-shelf technology. The hardware for a KELT telescope costs less than $75,000
  • – KELT–1b
  • Located approximately 825 light-years away in the constellation of Andromeda
  • Mostly metallic hydrogen, is slightly larger than Jupiter, but contains a whopping 27 times the mass
  • It tentatively been classed as a brown dwarf due to its mass
  • Completes one orbit in a mere 29 hours
  • Surface temperature is likely above 4,000 degrees Fahrenheit (~ 2,200 degrees Celsius)
  • Receiving 6,000 times the amount of radiation that Earth receives from the sun
  • – Kelt–2Ab
  • Located about 360 light-years away in the constellation of Auriga
  • 30 percent larger than Jupiter with 50 percent more mass.
  • KELT–2Ab’s parent star is so bright it can be seen from Earth through binoculars and is slightly bigger than the sun, within a binary system
  • One star is slightly bigger than our sun, and the other star is slightly smaller. KELT–2Ab orbits the bigger star, which is bright enough to be seen from Earth with binoculars
  • The star is so luminous that researchers will be able to make direct observations of the planet’s atmosphere by examining light that shines through it when the star passes within KELT North’s field of view again in November.
  • Follow-up observations are also being planned from both ground based and orbiting observatories including the Hubble Space Telescope and the infrared Spitzer Space Telescope.
  • Closely Orbiting Planets
  • Astronomers have discovered two alien planets around the same star, 200 light-years from Earth, whose orbits come so close together that each rises in the night sky of its sister world
  • This means they are closer than any other pair of planets known, and are about 20 times closer together than any two planets in our solar system
  • At their closest approach, the two planets are roughly three times closer to their host star than Mercury
  • The two planets meet up every 97 days in a conjunction that would make each dramatically visible in the other’s sky.
  • While they are as different in density as Earth and Saturn they are separated by five times the distance between the Earth and the moon [1.2 million miles/1.9 million kilometers]
  • The larger planet is pushing the smaller planet around more, so the smaller planet was harder to find
  • The timing of their orbits means they’ll never collide
  • – Kepler 36a
  • A star likely a bit hotter than our star
  • Several billion years older than our Sun, and at this time is known to have just two planets
  • – Kepler–36b
  • Has an orbit of about 14 days and sits about 11 million miles (18 million km) from the star.
  • Kepler–36b, appears to be a rocky “super-Earth” 4.5 times as massive as our planet
  • Probably has lava flows on its surface
  • A super-Earth just 1.5 times wider than our planet. Iron likely constitutes about 30 percent of its mass, water around 15 percent and atmospheric hydrogen and helium less than 1 percent
  • Probably formed relatively close to the star
  • – Kepler–36c
  • Has an orbit of about 16 days, at an average distance of 12 million miles (19 million km)
  • A gaseous, Neptune-size world about eight times as massive as Earth
  • About 3.7 times wider than Earth, likely has a rocky core surrounded by a substantial atmosphere filled with lots of hydrogen and helium
  • Likely took shape farther out

50 Gigapixel Mega Camera

  • The low down
  • Traditionally, one way of making better optics has been to add more glass elements, which increases complexity
  • Researchers have developed a prototype “supercamera” that stitches together images from 98 individual cameras to create a 960-million-pixel image
  • Significance
  • This camera captures up to 50 gigapixels of data, which is 50,000 megapixels, while most consumer cameras range from 8 to 40 megapixels
  • The resolution of this camera, five times better than 20/20 human vision, have enough resolution to spot a 3.8-centimeter-wide object 1 kilometer away
  • The prototype camera itself is two-and-half feet square and 20 inches deep, with only about 3% of the camera is made of the optical elements
  • The camera is so large now because of the electronic control boards and the need to add components to keep it from overheating
  • Other camera systems can generate gigapixel-and-larger images, those composite views are stitched together from individual images taken sequentially with one camera as it is panned across the scene
  • This new system takes all 98 images simultaneously, providing a “stop action” view of a scene, with some overlap
  • Of Note
  • Researchers believe that within five years, gigapixel cameras should be available to the general public
  • The camera is being developed by Duke’s Pratt School of Engineering, University of Arizona, University of California, and Distant Focus Corp

YouTube Channel : endangeredlanguages

  • The low down
  • Only half of the approximately 7,000 languages spoken today are expected to survive past the end of this century
  • Wed, June 21 Google introduced an Endangered Languages Project website where people can find, share, and store information about dialects in danger of disappearing.
  • Significance
  • Endangeredlanguages.com is designed to let users upload video, audio, or text files and encourages them to memorialize recordings of rare dialects.
  • A range of collaborators have already begun to contribute content ranging from 18th-century manuscripts to modern teaching tools like video and audio language samples and knowledge-sharing articles
  • Technology can strengthen these efforts, by helping people create high-quality recordings of their elders (often the last speakers of a language)
  • Of Note
  • Google’s philanthropic arm seeded the project, leadership of which will be ceded in coming months to the First People’s Cultural Council and the Institute for Language Information and Technology at Eastern Michigan University.
  • Endangered Languages Catalog (ELCat), is sponsored by the University of Hawaii, will also be contributing to the project.

A win for a positive work environment

  • The low down
  • A new study challenges previous research that says the threat of penalty is more effective for getting increased effort
  • Significance
  • A scientific experiment in which participants played the role of supervisor and employee
  • Some employees were subjected to a bonus program implemented by the supervisor, others worked under a penalty system.
  • Employees subjected to the bonus exhibited more effort and this was driven by greater trust in the supervisor
  • Those subjected to penalties tend to distrust the supervisor and, because of that, work less hard
  • Of Note
  • This study is the first to identify this trust factor.
  • This suggests that employees who receive bonuses for their efforts will work even harder, increasing productivity and potentially bolstering profits
  • Examples of penalties in the business world include pay reduction, demotion and sanction or other disciplinary action, such as a salesperson with lower performance getting less territory to work.

A possible new diagnostic tool for Parkinson’s Disease

  • The low down
  • Parkinson’s is a degenerative disease that slowly rob those afflicted of their faculties
  • Currently there is no blood test for the disease
  • Some notable people that have it are Michael J. Fox, Muhammad Ali, Andy Grove (one of the founders of chip maker Intel)
  • Mathematician Max Little has found a computer program he’s devised, is remarkably good at diagnosing the disease by analyzing voice alone.
  • Working on his PhD at Oxford applying math algorithms to voice disorders
  • During his work he found a repository of vocal recordings by Parkinson’s patients
  • The recordings were meant to be used as anecdotal testimony to help researchers learn more about the progression of the disease
  • Comparing 50 patient voices to non-afflicted people he found he was able to detect which voices belonged to those with the disease in 86% of cases
  • To increase the number of voices in the system Little has set up a website with phone numbers for people, both affected and not, to call in and leave a voice message to add to the database

The Shuttle Enterprise’s Tent

  • Last time on SciByte
  • SciByte 50 | Dinosaurs & Neutrinos : Shuttle Enterprise’s last landing
  • Significance
  • Two weeks after arriving on top of the aircraft carrier-turned-Intrepid Sea, Air & Space Museum in New York City, Enterprise is now underneath the inflatable canopy that will house its public display.
  • On Tuesday (June 19) Enterprise was covered by an opaque-white fabric shelter to protect it from exposure to the elements and to meet NASA’s display requirements for a climate-controlled facility
  • Some final work configuring the canopy is still underway however, including the removal of scaffolding that supported the fabric being raised, which led to it being deflated again.
  • The now pressurized enclosure extends over Enterprise’s tail, which tops out at 57 feet (17 meters) high, and beyond the shuttle’s 78-foot (24-meter) wingspan.
  • It occupies the rear of the Intrepid’s flight deck with the shuttle’s nose pointed out toward the Hudson River
  • The display is set to open to the public on July 19 when visitors will get the chance to closely view and circle around the prototype winged orbiter
  • Of Note
  • The location for the permanent Enterprise exhibit is still to be decided.
  • Intrepid officials have said that they are considering locations across the street from where the aircraft carrier is docked and also alongside the museum on the pier.

SCIENCE CALENDAR

Looking back

  • June 30, 1908 : 104 years ago : Tunguska Meteorite
  • At around 7:15 am, northwest of Lake Baikal, Russia, a huge fireball nearly as bright as the Sun was seen crossing the sky. Minutes later, there was a huge flash and a shock wave felt up to 650 km (400 mi) away. Over Tunguska, a meteorite over 50-m diameter, travelling at over 25 km per second (60,000 mph) penetrate Earth’s atmosphere, heated to about 10,000 ºC and detonated 6 to10 km above the ground. The blast released the energy of 10–50 Megatons of TNT, destroying 2,200 sq km of forest leaving no trace of life. Taurid Meteor storm that crosses Earth’s orbit twice a year. The first scientific expedition for which records survive was made by Russian mineralogist Leonid Kulik in 1927
  • In 1938, Kulik arranged for an aerial photographic survey of the area covering the central part of the leveled forest (some 250 square kilometres [97 sq mi]). The negatives of these aerial photographs (1,500 negatives, each 18 × 18 cm or 7.1 x 7.1 in) were burned in 1975 by order of Yevgeny Krinov, then Chairman of the Committee on Meteorites of the USSR Academy of Sciences.

Studying the high-altitude jet stream



Credit: NASA Wallops

  • The low down
    • After several days of delays due to the weather NASA launched the 5 ATREX rockets within 5 min of each other on March 27
    • Each of the rockets released a chemical tracer that was used to get more data of the high-altitude jet stream located 60–65 mi [95–105 km]
    • Two of the rockets also contained instruments to measure temperature and pressure
    • Hopefully this data will help us to better understand the processes behind this jet stream
  • Significance
    • The high-altitude jet stream that this project was looking at is much higher than the one in the nightly weather report
    • The upper jet-stream typically has winds of about 200–300 mph [320–480 km/hr] and is a region of electrical turbulence that can affect satellites and radio
  • Of Note
    • NASA will release more information about the outcome of the mission after scientists have had time to review the data

Counting Penguins from space



Credit: (left) DigitalGlobe; (right) British Antarctic Survey

  • The low down
    • A simple snap of a photograph of a penguin colony, and some marking can help scientist accurately count the number of penguins in a colony
    • Those numbers are hard to get however in remote places, especially in the Antarctic
    • A new technique uses satellite imaging to report results
  • Of Note
    • Scientists have now found twice as many Emperor penguins than thought to exist
    • This brings the total colonies to 44 (7 new ones) and ~595,000 (+/- 81,000)

SCIENCE CALENDER

Looking back

  • April 25, 1990 : 22 years ago : Hubble Space Telescope Deployed : In 1990, the $2.5 billion Hubble Space Telescope was deployed in space from the Space Shuttle Discovery into an orbit 381 miles above Earth. It was the first major orbiting observatory, named in honour of American astronomer, Edwin Powell Hubble. It was seven years behind schedule and nearly $2 billion over budget. In orbit, the 94.5-in primary mirror was found to be flawed, giving blurred images and reduced ability to see distant stars. However, correcting optics were successfully installed in 25 Dec 1993. The telescope 43-ft x 14-ft telescope now provides images with a clarity otherwise impossible due to the effect of the earth’s atmosphere. Instrument packages capture across the electromagnetic spectrum.

Runaway planets

  • The low down
  • In 2005, astronomers found evidence of a runaway star that was flying out of the Milky Way galaxy at a speed of 1.5 million mph (2.4 million kph).
  • In the seven years since, 16 of these hypervelocity stars have been found
  • Significance
  • A new study has found that planets themselves could be ejected from their star, and even escaping the Milky Way at a speedy to 30 million miles per hour, or a fraction of the speed of light
  • A typical runaway planet would likely dash outward at 7 to 10 million mph (11.3 to 16.1 million kph),
  • Under the right circumstances, a few could have their speeds boosted to up to 30 million mph (48.3 million kph)
  • At those speeds they could be the fastest large solid objects, and could cross the diameter of the Earth in 10 sec
  • These hypervelocity planets could escape the Milky Way and travel through interstellar space
  • * Of Note*
  • Planets that are in tight orbits around a runaway star could travel with them, and be visible from dimming as it transits
  • This is the first time that scientists are discussing searching for planets around hypervelocity stars

Lego’s can help build bones too

  • The low down
  • Bone has excellent mechanical properties for its weight
  • Synthetic bone has a range of applications; from the obvious, such as medical implants, to a material used in building construction
  • Researchers at Cambridge making synthetic bone have turned to legendary children’s toy Lego for a helping hand.
  • Significance
  • To ‘grow’ a synthetic bone like substance, the researchers first dip a sample into a beaker of calcium and protein, then rinse it in some water and dip in into another beaker of phosphate and protein
  • The process must be repeated over and over to build up the structure, which is time consuming and tedious
  • So the team looked into ways of automating the process, ideally a robot that could simply run while the team worked on other things and/or overnight
  • One solution for acquiring a robot was to purchase an expensive kit off the shelf from a catalog
  • Looking for a cheaper solution the team realized Lego could be the simplest, and cheapest, solution
  • So the team decided to build cranes from a Lego Mindstorms robotics kit
  • They programmed it to perform basic tasks on repeat, using microprocessors, motors, and sensors
  • The sample is tied to string at the end of the crane which then dips it in the different solutions
  • * Of Note*
  • The researchers are also working on hydroxyapatite–gelatin composites to create synthetic bone, of interest because of its low energy costs and improved similarity to the tissues they are intended to replace.

Sorry some coffee lovers

  • The low down
  • While stimulants may improve unengaged workers’ performance, a new University of British Columbia study suggests that for others, caffeine and amphetamines can have the opposite effect, causing workers with higher motivation levels to slack off.
  • Significance
  • Researchers studied the impacts of stimulants on “slacker” rats and “worker” rats, and sheds important light on why stimulants might affect people differently
  • For slacker rats, amphetamine sharpened the mental work ethic, making them more likely to choose the harder task.
  • For workers; however, amphetamine caused the animals to choose the easier option more.
  • Researchers can’t yet explain why stimulants would cause workers to choose the easier task
  • One possibility is that hard workers are already performing optimally, so any chance to the system could cause a net decrease in productivity.
  • * Of Note*
  • This study indicates that people being treated with stimulants would better benefit from a more personalized treatment programs.

Einsteins library

  • The low down
  • Albert Einstein’s complete archive is gradually becoming available through the Einstein Archives Online
  • The archive when fully uploaded will have more than 80,000 documents.
  • The archive will contain everything from manuscripts containing the famous E=mc^2 equation written in Einstein’s handwriting to postcards to his mother
  • * Of Note*
  • Einstein was an excellent student, who left school because he couldn’t handle the strict discipline and authority.

SPACECRAFT UPDATE

You could bring about the next great Hubble picture

  • The low down
  • Since 1990, Hubble has made more than a million observations
  • The main way to get Hubble data is the Hubble Legacy Archive website, where a search box lets you look for objects based on their name or coordinates or even which camera on Hubble
  • Realize that Hubble has not been able to observe all objects in the night sky and that scientists get the first chance to work with their data, releasing it to the public a year after they have been made
  • Significance
  • Over a million observations of the Universe have been made by the Hubble Space Telescope. Spacetelescope.org is asking the public to sift through the archives, adjust the colors of their favorite photos with an online tool, and submit to the contest
  • You can search Hubble’s archive for hidden treasures even if you don’t have advanced knowledge
  • It is recommend that people narrow their search to give only results from ACS, WFC3 and WFPC2 – Hubble’s general purpose cameras, as not all of Hubble’s observations are images
  • An interactive tool on the website allows you to look at the image in more detail, and carry out basic image processing such as adjusting the zoom and changing the contrast and colour balance
  • You can save your work as a JPEG
  • The process is entirely browser-based, however you can download the image in a FITS format so you use more advanced software to process the images
  • * Of Note*
  • Images from Hubble are look at the image in more detail, and carry out basic image processing such as adjusting the zoom and changing the contrast and colour balance, containing far more information that the eye can see
  • The beautiful iconic Hubble images seen by the public have been extensively tweaked and optimised by hand, in order to reveal as much of the data as possible

SCIENCE CALENDER

Looking back

  • Apr 07, 1927 : 85 years ago : First Television Broadcast : In 1927, the first public display of a long distance television transmission was viewed by a group of newspaper reporters and dignitaries in the auditorium of AT&T Bell Telephone Laboratories, New York. The research at AT&T was led by Herbert Ives, who introduced the system to the audience, followed by a broadcast speech by the then Secretary of Commerce, Herbert Hoover from Washington, D.C.. Both the live picture and voice were transmitted by wire, over telephone lines. Hoover said,“Today we have, in a sense, the transmission of sight for the first time in the world’s history,” and also, “Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown.” The accomplishment was heralded with great acclaim by the press
  • Apr 06, 1930 : 82 years ago : Twinkies!!! : In 1930, Hostess Twinkies snack cakes were invented by James “Jimmy” A. Dewar, plant manager at Continental Baking Company, Chicago as an inexpensive product at the time of the Great Depression. He realized the factory had baking pans for sponge cakes used only during the summer strawberry season, and that they could be made useful year-round for a new product: sponge cakes injected with a banana creme filling. They originally sold at two for a nickel. Vanilla creme was substituted during the WW II banana shortage. The name is said to have come to him based on a billboard he saw for “Twinkle Toe” shoes.

Saturn moon with an atmosphere

  • The low down
  • The Cassini mission was launched in 1997 and it has been orbiting Saturn since its arrival at the ringed planet in 2004, as a joint effort by NASA and the space agencies of Europe and Italy, and has been extended several times, most recently until 2017.
  • Dione is one of Saturn’s smaller moons 698 miles (1,123 km) wide, and orbits Saturn once every 2.7 days at a distance roughly the same as that between Earth and its moon, about 234,000 miles [377,400 km].
  • Discovered in 1684 by astronomer Giovanni Cassini, it is one of 62 known moons orbiting the ringed planet.
  • According to new findings from the Cassini-Huygens mission announced Friday, March 2 molecular oxygen ions were seen near Dione’s icy surface, giving it a wispy oxygen atmosphere.
  • Significance
  • An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
  • The oxygen on Dione may potentially be created by solar photons or high-energy particles that bombard the Saturn moon’s ice-covered surface, kicking up oxygen ions in the process
  • Another idea suggests that geologic processes on Dione could feed the moon’s atmosphere, researchers added.
  • Scientists used the measurements to estimate the density of the molecular oxygen ions to be in the range of one oxygen ion for every 2,550 cubic feet (90,000 cubic meters, 0.01 to 0.09 ions per cubic centimetre
  • The atmosphere is 5 trillion times less dense than the air at Earth’s surface, equivalent to conditions 300 miles [480 kilometers] above Earth.
  • * Of Note*
  • This study shows that molecular oxygen is actually common in the Saturn system and reinforces that it can come from a process that doesn’t involve life
  • It now looks like oxygen production is a universal process wherever an icy moon is bathed in a strong trapped radiation and plasma environment

Heart Powered Pacemaker

  • The low down
  • The device harvests energy from the reverberation of heartbeats through the chest and converts it to electricity to run a pacemaker or an implanted defibrillator.
  • It would be powered from an unlikely source: vibrations from heartbeats itself
  • The device would be placed in the thoracic artery, an extra blood vessel often removed in heart surgery.
  • Significance
  • New energy harvester could save patients from repeated surgeries. That’s the only way today to replace the batteries, which last five to 10 years.
  • It would generate 10 micro-watts of power, which is about eight times the amount a pacemaker needs to operate
  • The researchers have precisely engineered the ceramic layer to a shape that can harvest vibrations across a broad range of frequencies
  • Piezoelectric materials’ claim to fame is that they can convert mechanical stress (which causes them to expand) into an electric voltage and would essentially catch heartbeat vibrations and briefly expand in response
  • If they incorporate magnets, whose additional force field can drastically boost the electric signal that results from the vibrations.
  • * Of Note*
  • The technology was originally designed the harvester for light unmanned airplanes, where it could generate power from wing vibrations
  • Researchers haven’t built a prototype yet, but they have made detailed blueprints and run simulations demonstrating that the concept would work.

Hot-Spring Fossil Forest

  • The low down
  • In southern Argentina, in Patagonia, geothermal deposits include animals, plants, fungi and bacteria, preserved in three dimensions and with their internal structure largely intact.
  • The fossils date from around 150 million years ago, and is the first time a hot-spring habitat from the Mesozoic era (from about 250 to 65 million years ago) has ever been discovered.
  • Significance
  • The newly uncovered area was preserved in such a way that we were where they had stood and how big they had grown
  • This is not the type of fossilization typically thought of where living tissues were crushed into a two-dimensional film
  • Instead plant tissues and cells were permeated by water containing dissolved silica, which was precipitated prior to plant decay and resulted in magnificent three-dimensional preservation of complete plants
  • By cutting, polishing, and thinly sectioning blocks from the deposit and then examining the preserved fossils with high-powered microscopes, scientists are able to describe in intricate detail the anatomy and morphology.
  • This type of process allows scientists to literally walk among the trees, noting what kind they were
  • * Of Note*
  • The remains of everything from the bacteria living right around the hot spring vents all the way to the plants, crustaceans and insects living in wetlands further away and the trees and ferns from the forests around the margins.
    +The discovery of a rich assemblage of fossils from between these extremes could transform scientists’ understanding of a vital stage in life’s development

Europa’s ocean may be acidic

  • The low down
  • Europa, which is roughly the size of Earth’s moon, could possess an ocean about 100 miles deep
  • Europa’s interior. The moon is thought to have a metallic core surrounded by a rocky interior, and then a global ocean on top of that surrounded by a shell of water ice
  • The ocean underneath the icy shell of Jupiter’s moon Europa could be too acid to support life
  • Recent findings even suggest its ocean could be loaded with oxygen, enough to support millions of tons worth of marine life like the kinds that exist on Earth
  • Significance
  • Oxidants from Europa’s surface might react with sulfides and other compounds in this moon’s ocean before life could nab it generating sulfuric and other acids
  • The ocean could become relatively corrosive, with a pH of about 2.6, about the same as the average soft drink
  • Life that could form there would be analogous to microbes found in acid mine drainage on Earth, like the bright red Río Tinto river in Spain
  • The dominant microbes found there are acid-loving “acidophiles” that depend on iron and sulfide as sources of metabolic energy microbes there have figured out ways of fighting their acidic environment
  • If life did that on Europa, Ganymede, and maybe even Mars, that might have been quite advantageous
  • Further Reading / In the News
  • Europa’s Acidic Oceans May Prohibit Life @ universetoday.com
  • Acidic Europa may eat away at chances for life @ physorg.com

Facebook and Job Performance

  • The low down
  • Can a person’s Facebook profile reveal what kind of employee he or she might be? The answer is yes, and with unnerving accuracy
  • A prospective employer might be able to glean from your Facebook profile is a openness to new experiences (vacation pictures from a glacier off New Zealand), emotional stability (are your friends constantly offering you words of comfort?) and agreeableness (are you constantly arguing with "friends
  • Significance
  • Six people with experience in human resources were asked to rate a sample of 500 people in terms of key personality traits using only 5–10 minutes on a persons Facebook page as a guideline.
  • They evaluators were asked to rate members of the sample group on what is known as the “Big Five” personality traits : extroversion, conscientiousness, emotional stability, agreeableness and openness to new experiences
  • Members of the sample group were asked to give a self-evaluation and took an IQ test.
  • High ‘Facebook’ scores were an indication of future good job performance
  • These ratings were followed up with the employers in the sample group six months after their personality traits were rated, to ask questions about job performance.
  • Raters were generally in agreement about the personality traits expressed in the sample group’s Facebook page
  • Ratings also correlated strongly with self-rated personality traits
  • In fact the Facebook ratings were a more accurate way of predicting a person’s job performance than an IQ test
  • * Of Note*
  • Facebook page can provide a lot of information that it would be illegal for an employer to ask of a candidate in a phone interview gender, race, age and whether they have a disability
  • In fact 90 percent of recruiters and hiring managers look at an applicant’s Facebook page whether they should or not.
  • Further Reading / In the News
  • Study: Facebook profile beats IQ test in predicting job performance

Transistors the Crumple

  • The low down
  • Thanks to the flexible yet robust properties of carbon nanotubes, researchers have previously fabricated transistors that can be rolled, folded, and stretched
  • Japan has made an all-carbon-nanotube transistor that can be crumpled like a piece of paper without degradation of its electrical properties
  • This study could lead to active electronic devices that are applied like a sticker or an adhesive bandage, as well as to wearable electronics.”

Chronic pain

  • The low down
  • It has long been known that the central nervous system “remembers” painful experiences, that they leave a memory trace of pain.
  • Researchers have now found the key to understanding how memories of pain are stored in the brain
  • The best example of a pain memory trace is found with phantom limb pain
  • When the brain remembers that pain there is a new sensory input, the pain memory trace in the brain magnifies the feeling so that even a gentle touch can be excruciating
  • There is evidence that any pain that lasts more than a few minutes will leave a trace in the nervous system
  • It is this memory of pain, which exists at the neuronal level, that is critical to the development of chronic pain.
  • Until now however it was not known how these pain memories were stored at the level of the neurons
  • Significance
  • Recent studies have now that the the protien kinase PKMzeta both maintains memory and strenghtens the connections between neurons
  • The level of PKMzeta increases persistently in the central nervous system (CNS) occurs after painful stimulation
  • New research shows that by blocking the activity of the PKMzeta at the neuronal level, they could reverse the hypersensitivity to pain that neurons developed after applying an irritating stimulation on the skin.
  • In fact, erasing this pain memory trace was found to reduce both persistent pain and heightened sensitivity to touch
  • * Of Note*
  • Most of the current medications for persistent pain from arthritis, injury, fibromyalgia or other nerve diseases simply apply analgesia systems in the brain or reduce inflammation to reduce the feeling in the brain
  • With PKMzeta could actually target the pain memory trace itself as a way of reducing pain hypersensitivity
  • Further Reading / In the News
  • Neuron memory key to taming chronic pain

SCIENCE CALENDER

Looking back

  • Mar 10, 1876 : 136 years ago : Pass GO, collect $200 : In 1933, the game “Monopoly” was created and trademarked by Charles Darrow in Atlantic City. It was preceded by other real estate games. The first, called “The Landlord’s Game,” was invented by Lizzie Magie of Virginia (patented 1904). In it, players rented properties, paid utilities and avoided “Jail” as they moved through the board. Darrow set about creating his own version, modeled on his favorite resort, Atlantic City. He made numerous innovations for his game, which had a circular, cloth board. He color-coded the properties and deeds for them, allowing them to be bought, not just rented. The playing pieces were modelled on items from around his house. It was mass marketed by Parker Brothers in 1935.
  • Mar 07, 1933 : 79 years ago : Alexander Graham Bell : In 1876, Alexander Graham Bell made what was, in effect, the first telephone call. His assistant, Thomas Watson, located in an adjoining room in Boston, heard Bell’s voice over the experimental device say to him, “Mr. Watson, come here. I want you.” This was Bell’s first successful experiment with the telephone, which is recorded in the 10 Mar entry of his Lab Notebook. That same day, an ebullient Bell wrote his father of his “great success” and speculated that “the day is coming when telegraph [phone] wires will be laid on to houses just like water and gas - and friends converse with each other without leaving home.” Bell had received the first telephone patent three days before. Later that year, Bell succeeded in making a phone call over outdoor lines.

Support Satellites

  • Metalfreak also wanted to make sure I saw this story, Thanks!
  • Cleanup Satellite – The low down
  • Orbiting the Earth is a growing crowd of abandoned satellites, spent rocket stages, bits of broken spacecraft, and fragments from collisions are rocketing around the planet at breathtaking speeds
  • NASA keeps close tabs on at least 16,000 of these objects that are larger than 10 cm in diameter.
  • If a collision destroys a satellite, the collision itself then generates thousands more fragments, further exacerbating the problem.
  • Cleanup Satellite – Significance
  • CleanSpace One will grab and stabilize a target, a mission that’s extremely dicey at high speeds with a potentially rotating satellite.
  • To accomplish the task, scientists are planning to develop a gripping mechanism inspired from a plant or animal example.
  • Once it’s coupled with the satellite, CleanSpace One will “de-orbit” the unwanted satellite by heading back into the Earth’s atmosphere, where the two satellites will burn upon re-entry.
  • The first model is destined to be destroyed, but the CleanSpace One adventure will not be a one-shot deal
  • The company wants to offer and sell a whole family of ready-made systems, designed as sustainably as possible, that are able to de-orbit several different kinds of satellites
  • Recycling Satellite – The low down
  • United States Department of Defense is looking for ways to repurpose space junk thousands of miles above Earth back into valuable satellite parts, or even completely new spacecraft
  • A program called Phoenix, which seeks to recycle still-functioning pieces of defunct satellites and incorporate them into new space systems on the cheap.
  • Recycling Satellite – Significance
  • The Phoenix program aims to use a robot mechanic-like vehicle to snag still-working antennas from the many retired and dead satellites in geosynchronous orbit and attach them to smaller “satlets,” or nanosatellites, launched from Earth.
  • Phoenix could save the military a lot of money on launch costs, DARPA officials said. Antennas are big and bulky, requiring a lot of fuel to get off the ground, while lofting the antenna-less “satlets” would be much cheaper.
  • Satellites in GEO are not designed to be disassembled or repaired, so it’s not a matter of simply removing some nuts and bolts
  • The Phoenix program can look to some ground-based tech as a starting point, officials said. For example, it may incorporate elements of today’s telerobotics systems that allow doctors to perform surgery on patients thousands of miles away, as well as advanced remote imaging systems that enable oil drillers to view the ocean floor thousands of feet underwater.
  • Refueling Satellite – The low down
  • Canada-based aerospace firm MacDonald, Dettwiler and Associates Ltd. is designing a spacecraft that will serve as an orbiting gas station and mechanic
  • Rocket fuel is cryogenic, meaning super-cold substances like liquid oxygen and liquid hydrogen
  • NASA awarded contracts to four companies with plans to study how to store and transfer fuel in space.
  • Refueling Satellite – Significance
  • Often a satellite becomes ‘defunct’ when it runs out of fuel
  • Canada-based aerospace firm MacDonald, Dettwiler and Associates Ltd. is designing a spacecraft that will serve as an orbiting gas station and mechanic
  • * Of Note for all three support type satellites*
  • Reduce orbital debris. Depending on the funding and industrial partners, this first orbital debris rendez-vous could take place within three to five years.
  • Reuse Satellites after being refueled. Depending on the funding and industrial partners, this first refueling orbital rendez-vous could take place within three to five years.
  • Recycle Old satellite dishes and parts for new satellites. Should the Phoenix program work space debris would become a space resource

Robonaut 2

  • The low down
  • Robonaut is a dexterous humanoid robot
  • It was designed to meet the challenge to build machines that can help humans work and explore in space
  • They can work side by side with humans, or going where the risks are too great for people and could expand our ability for construction and discovery
  • The value of a humanoid over other designes, is that they have the ability to use the same workspace and tools
  • Not only does humanlike dexterous manipulation improve efficiency in the types of tools, but also removes the need for specialized robotic connectors
  • A suite of cameras in its head not only provide R2’s operators in space and on the ground with a view of what it’s working on, they can also be used by the robot to verify the configuration of a switch its flipped or ensure that other work it has done is correct
  • Significance
  • On Feb 15, 2012 it completed its initial checkouts on board the International Space Station it made history with the first human/robotic handshake to be performed in space
  • After the handshake it sent down a message in sign language. “Hello World,” the robot signed in American sign language
  • Following the tests, R2 was powered down and put back into storage until time for the robot
  • * Of Note*
  • Robonaut 2 (R2) marks the first dexterous humanoid robot in space
  • R2, launched to the International Space Station on space shuttle Discovery as part of the STS–133 mission a year ago
  • Next steps include a leg for climbing through the corridors of the Space Station, upgrades for R2 to go outside into the vacuum of space, and then future lower bodies like legs and wheels to propel the R2 across Lunar and Martian terrain
  • After vision characterization, the robot will be able to work with the taskboards sent into space
  • Following the tests, R2 was powered down and put back into storage until time for the robot

Science figures out an Ancient herbal remedy again

  • Last time on Sci-Byte
  • Space Station and Lizards | SciByte 19 – Nov 1, 2011 (Snake Oil)
  • Moons Here & There | SciByte 28 – Jan 10, 2012 (The anti-alcohol drug that lessens hangovers too?)
  • The low down
  • An autoimmune disease is when the immune system mistakes some part of the body as a pathogen and attacks its own cells.
  • A central challenge for improving autoimmune therapy is preventing inflammatory pathology without inducing generalized immuno-suppression
  • For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan
  • Researchers from the Harvard School of Dental Medicine have discovered the molecular secrets behind this herbal extracts power, Halofuginone.
  • Significance
  • Halofuginone (HF), a compound derived from this extracts bio-active ingredient, could be used to treat many autoimmune disorders.
  • Halofuginone received FDA orphan drug status (pharmaceutical agents that have been developed specifically to treat a rare medical condition) and has been used to treat sclerderma, a connective tissue disease, since 2000.
  • Hydroxylation, an oxidative process adding -OH, of proline is a critical biochemical process for maintaining the connective tissue of higher organisms.
  • Halofuginone, targeted and inhibited a particular enzyme (tRNA synthetase EPRS) responsible for incorporating proline into proteins that normally contain it.
  • This process kick started an amino acid response pathway, or AAR, response and produced the therapeutic effects of HF-treatment.
  • When a cell senses a limited supply of amino acids for building proteins, AAR will block signals that promote inflammation because inflamed tissues require lots of protein.
  • Halofuginone triggers a stress-response pathway that blocks the development of a harmful class of immune cells
  • The researchers think that HF treatment mimics cellular proline deprivation, which activates the AAR response and subsequently impacts immune regulation. .
  • Researchers do not yet fully understand the role that amino acid limitation plays in disease response or why restricting proline inhibits Th17 cell production.
  • Recognized only since 2006, Th17 cells are implicated in many autoimmune diseases such as inflammatory bowel disease, rheumatoid arthritis, multiple sclerosis and psoriasis
  • * Of Note*
  • Halofuginone prevents the autoimmune response without dampening immunity altogether
  • This compound could inspire novel therapeutic approaches to a variety of autoimmune disorders

Spray on antennas

  • The low down
  • The idea of a spray-on antennas on surfaces does have a history.
  • In 2001 Researchers were studying applications and materials for creating radio antennas that are sprayed onto a surface. Made from commercially available materials, these devices consist of a conductive substance sprayed over a template with a radio aerial pattern on it.
  • Researchers have continued studying applications and materials for creating radio antennas that are sprayed onto a surface.
  • Now a startup company has unveiled at Google’s Solve for X “conference” a spray-on signal booster in a can that promises an improved signal.
  • Significance
  • The company, Chamtech Enterprises, tested the spray on a tree, among other tests, and the team was able to send a VHF signal up to 14 miles away using only the treated tree.
  • The company is upbeat over successful tests that were run to examine the spray’s signal performance submerged at periscope depth, communicating over a nautical mile at 50Mhz, 3W
  • Technology could be used by weather and oceanographic researchers and underwater welders.
  • * Of Note*
  • The company also hopes for a wider customer base including mobile phone makers and manufacturers of medical devices.

Desalination Water

  • Thanks Allan from TechSnap
  • The low down
  • Desalination, desalinization, or desalinisation refers to any of several processes that remove some amount of salt and other minerals from saline water
  • Water is desalinated in order to convert salt water to fresh water so it is suitable for human consumption or irrigation.
  • Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use in regions where the availability of fresh water is, or is becoming, limited.
  • Many of today’s desalination plants use reverse osmosis or evaporation, both of which require enormous amounts of energy to supply heaters or high-pressure pumps.
  • To find cheaper, room-temperature, energy-efficient solutions, many researchers are looking to nanomaterials and electrochemistry.
  • * Of Note*
  • It first draws ions from seawater into a pair of electrodes.
  • As the researchers pass current through the electrodes, electrochemical reactions drive chloride ions into a silver electrode and sodium ions to an electrode made from manganese oxide nanorods.
  • Next, the researchers remove the desalinated water and release the trapped ions into a separate stream of waste seawater by reversing the direction of the electrical current
  • pilot experiments were not automated, the researchers say that a pump could automate the process.
  • The desalination system is a spinoff from a Stanford University project to create new sources of clean energy
  • The desalinated water that comes from the battery still contains too much salt for drinking, La Mantia says: “We removed up to 50% of the original salt, but we need to arrive at 98%.”

Sub Glacial Lakes

  • *Sub Glacial Lakes? *
  • The idea of lakes hidden under Antarctic ice was first put forward by Russian scientist Prince Pyotr Kropotkin
  • Russian geographer noted the likely location of the lake
  • It wasn’t until 1994 that Russian and British scientists got
    sonar and satellite imagining to reveal one of the world’s largest undisclosed fresh water reservoirs
  • These kind of lakes would be kept from freezing into a solid block by the mammoth crust of ice across it that acts like a blanket, keeping in heat generated by geothermal energy underneath.
  • * Meet Lake Vostok *
  • Lake Vostok is 160 miles [250 kilometers] long and 30 miles [50 km] across at its widest point, similar in area to Lake Ontario
  • Making Lake Vostok the largest of nearly 400 sub glacial lakes in Antarctica
  • Hidden under ice for millions of years beneath an almost impenetrable layer of ice if will provide a unique closed ecosystem captured in time below four kilometers of ice
  • According to Russian scientists the quantity of oxygen there exceeds that on other parts of our planet by 10 to 20 times
  • * The opposition *
  • There have been fears of any expedition reaching and possible contaminating the lakes
  • The Russian team has been using 60 metric tons (66 tons) of lubricants and antifreeze used in the drilling
  • There were many fears and concerns that those lubricating fluids could contaminate the pristine lake
  • The Russian team had waited for several years to receive international approval for it’s drilling technology before proceeding and was doing its best “to try really hard to do it right” and avoid contamination
  • * The Russian Journey *
  • Lake Vostok is about 800 mi [1,300 km] southeast of the South Pole in the central part of the continent.
  • At –126 F [–89C] and more than 11,000ft [3.300m] above sea level surface conditions mean that there is a limited window of opportunity to work each year
  • After more than two decades of drilling in Antarctica the head of Russia’s Arctic and Antarctic Research Institute likened ii to the race to the moon
  • In February 2011 after drilling 3720 meters last February, time ran out for the team and the project was stymied just 29.5 meters from its destination as winter set in.
  • With the Antarctic summer season nearing it’s end this year, some reports had the team going silent for a week
  • Then the news started trickling in that they had achieved breakthrough
  • They knew they had breakthrough when about 50 cubit ft [1.5 cubic m] of kerosene and freon poured up to the surface tanks from the bore-shaft, proof that the lake water streamed up from underneath, froze and then blocked the hole, sealing off the chance that any toxic chemicals could contaminate.
  • Scientists will return during the next Antarctic summer season, in December, to remove the frozen sample for analysis
  • * Other Expeditions *
  • American and British teams are drilling to reach their own smaller and younger sub glacial Antarctic lakes
  • British scientists that hopes to retrieve samples next year from another sub glacial lake, Lake Ellsworth in West Antarctica
  • Americans scientists are drilling at Lake Whillans, west of the South Pole
  • Another U.S. team is seeking to reach the river-fed Whillans Ice Stream, also in West Antarctica
  • * Of Note *
  • Russian ice cores retrieved so far have suggested the presence of heat-loving microorganisms called thermophiles, suggesting hot geothermal vents like those in the ocean may exist at the bottom of the lake
  • If a life form could exist here, it could also exist in similar environments such as Jupiter’s satellite, Europa.
  • In the future, Russian researchers plan to explore the lake using an underwater robot equipped with video cameras that would collect water samples and sediments from the bottom of the lake, a project still awaiting the approval of the Antarctic Treaty organization.

Another exciting step against Alzheimer’s

  • * Last time on SciByte*
  • SciByte 24 | Habitable Planets & Chimps
    (Dec 07, 2011)
  • The low down
  • Studies have identifies a link between the primary genetic risk factor for Alzheimer’s disease and a potential therapy to address it.
  • Humans have three forms of ApoE: ApoE2, ApoE3, and ApoE4. Possession of the ApoE4 gene greatly increases the likelihood of developing Alzheimer’s disease.
  • It has been seen that the main cholesterol carrier in the brain, Apolipoprotein E (ApoE), facilitates the clearance of the amyloid beta proteins
  • New hope is now coming from a drug that has been used to treat T-cell lymphoma often after other treatments have failed for more then a decade
  • Significance
  • The study mentioned before was using a synthetic liver x-receptor to remove amyloid beta from the brain.
  • Bexarotene acts by stimulating retinoid X receptors (RXR), which control how much ApoE is produced and seems to be reprogramming the brain’s immune cells to “eat” or phagocytose the amyloid deposits.
  • Researchers were struck by the speed with which bexarotene improved memory deficits and behavior even as it also acted to reverse the pathology of Alzheimer’s disease.
  • Just hours after treatment levels started falling, with 25% clearing after 24 hours, more than half within 72 hours and 75% after 14 days.
  • Even more impressive, the effect lasted as long as three days.
  • * Of Note*
  • The next step is to ascertain if it acts similarly in humans.
  • Since this drug has already been approved by the FDA and has a good safety and side-effect profile it likely to move into human trials much quicker than a new drug would.
  • Correct dosing presents another challenge as giving bexarotene over several doses appeared to be less effective than giving it once.
  • One reason may be that the drug degrades itself within the body.

    (jAN 31, 2012)
  • The low down
  • The Canadian teens were inspired by a similar near-space photography experiment by a pair of MIT students, who captured impressive views of the stratosphere with a digital camera attached to a helium balloon that 16 miles [25 kilometers]
  • Significance
  • MIT has been sending out acceptance letters to students in tubes, and the school challenged the potential newcomers to “hack” them in creative ways.
  • One ecstatic studens who had worked on balloon experiments before and is a Ham Radio operator in her spare time, came up with the idea to turn her tube into a high-altitude balloon experiment.
  • * Of Note*
  • The canister was equipped with tracking devices and an onboard camera,.
  • It reached a maximum altitude of approximately 17.2 miles [27.7 kilometers]
  • She predicted the path very accurately using a software algorithm to predict the wind patterns based on current weather information from regional airports
  • It only 75 miles east of its launch site after a two-hour flight

Arsenic life forms?

  • * Last time on J@N*
  • J@N | World Changing Fail
  • The low down+ They found microbes in a lake HERE ON EARTH that have arsenic in their protein structure in the place of phosphorous.
  • This is akin to the science-fiction theory that lifeforms could thrive replacing carbon with silicon
  • Scientists attempting to duplicate the finding have come up empty-handed
  • Significance
  • One problem was that the original team didn’t do certain experiments, such as attaching a radioactive tag to the arsenate and locating exactly where it turned up in GFAJ–1’s DNA.
  • The microbe in question clearly thrives in the presence of the usually toxic substance, there is no evidence that the bacterium requires arsenic to live or incorporates the element in its DNA
  • The original team did note that there sample could have been contaminated by a little phosphate.
  • When the new team did so, GFAJ–1 grew in densities similar to those reported before
  • * Of Note*
  • The researcher who lead the original team has reported much of her work on her research blog as it was being conducted, said the samples did contain trace amounts of arsenate.
  • Any microbe that can tolerate a bit of arsenic here or there without any serious effects would incorpersate some arsenate
  • The original researcher won’t comment further until the details of the new paper are published in a peer reviewed paper.
  • She also said that the original paper never actually claimed that arsenate was being incorporated in GFAJ–1’s DNA, and that other had ‘jumped to that conclusion’
  • This is again an issue that some of the scientific community the point discussion is essentially over, while others sill still wait for further results to clarify the issue.

6 Myths Everyone Believes about Space (Thanks to Movies) | Cracked.com

  • Angela, from the FauxShow

  • Asteroid Belts Are Deadly

  • In the media : Many times in movies or television shows the characters are dodging and weaving through colliding rocks of death.

  • In reality : Asteroids are actually not at all that packed together. Scientists at NASA have said that the odds of one of their probes traveling through the asteroid belt colliding with as asteroid were less than one in a billion. Some calculations provide an average of 400,000 square miles for each asteroid.

  • Black Holes Are Cosmic Vacuum Cleaners

  • In the media : They eat planets, and in general are trying to eat everything in the universe.

  • In reality : If we replaces our sun with a black hole of the same mass? … It would get colder. Something the mass of the sun, even a black hole, can not exert any more gravitational force.

  • The Sun Is Yellow

  • In the media : Get your crayons, draw the sun … hope you grabbed yellow …

  • In reality : The sun, at a warm 6,000K, has to be white. It’s the Earths atmosphere bends the light that keeps yellow crayons in business. The pictures we get from space are color enhanced based often based on composition, approximations or color filters.

  • Meteorites Are Hot

  • In the media : Oh no! A huge ball of flaming rock with a huge trail of smoke is headed for … fill in city/building/location here

  • In reality : In space they are about 3K, and have been so for billions and billions of years. They spend a few minutes in our atmosphere, and generally land lukewarm. What about the bright light you see when they are coming down? As the meteor comes down it is pushing the air in front of it away, the compression heats the air to the point where the air catches on fire.

  • People Explode in the Vacuum of Space

  • In the media : In space no can hear you scream … or explode … or at least have your eyes try to pop out.

  • In reality : Our skin actually does a pretty good job of protecting us. If you were in space your skin would keep you from exploding, and your blood would continue too pump until space absorbed enough of your body heat. Breathing is the real issue, and lung trauma. You will still die in space, but nothing as exciting as the movies would like you to believe

  • There Is a Permanent Dark Side of the Moon

  • In the media : In the dark wastelands of the dark side of the moon, which we never see ancient alien technology can remain frozen forever …

  • In reality : The moon may be in a tidally locked orbit so that we only see one side. There is a far side of the moon, that we never wee, it does the light of day .. or space. Simply speaking when there is a solar ecplise the moon blocks the sun from view, and is only one side of the moon ever faces us, the far side of the moon is completely bathed in the light of the sun.

  • Feb 16, 1923 : 89 years ago : Tutankhamen says Hello World : Archaeologist Howard Carter opened the sealed doorway to the sepulchral chamber of King Tutankhamen’s tomb in Thebes, Egypt. A group of invited visitors and officials was present, including Lord Carnarvon, the aristocratic Englishman who had funded the excavation. On 18 Feb 1923, the Queen of the Belgians and numerous visitors attended an official opening. The following day, the press was admitted. The pharoah reigned around 1350 B.C. The famous “Yes, wonderful things” quote came when they breached the tomb and peered in the door the November before
  • Feb 21, 1953 : 59 years ago : Deoxyribose Nulclei what? : Francis Crick and James Watson reached their conclusion about the double helix structure of the DNA molecule. They made their first announcement on Feb 28, and their paper, A Structure for Deoxyribose Nucleic Acid, was published in the 25 Apr 1953 issue of journal Nature.
  • Feb 18, 1977: 35 years ago : The Enterprise takes a test drive : The first space shuttle orbiter prototype, the Enterprise, was flight tested for two hours in “inert captive mode,” attached to the top of a 747 jumbo jet. The flight was the first of five captive flights in the nine-month-long Approach and Landing Test testing program (Feb-Nov 1977) at the Dryden Flight Research Facility. The orbiter was originally to be known as Constitution (to honour the U.S. Constitution’s Bicentennial). However, a write-in campaign by fans of the TV show Star Trek convinced the White House to name the vehicle Enterprise. PIC : Inert Flying Mode

  • The low down on Weather Balloons
  • Made of latex for synthetic runner typically about 0.002in [0.051mm] thick on the ground and 0.000098in [0.0025mm] at bursting altitude
  • On the ground they are about 6ft [1.8m] wide and expand to 20ft [6.9m] in diameter at altitude and can be filled with either hydrogen or helium
  • Can reach altitudes of 25mi [40km] and twice a day, every day of the year, weather balloons are released simultaneously from almost 900 locations worldwide!
  • Where does space begin? – It’s a complicated answer because there is no definitive answer. NASA awards astronaut wings to anyone who reaches 49.7mi [80km.] Other instruments and scientists argue that it begins at around 62mi [100km]
  • Significance
  • Two 17 years old Canadians, used a helium filled weather balloon that brought a homemade styrofoam capsule that included two video cameras, four digital cameras, a GPS-enabled cell phone, and a tine Lego man holding a Canadian flag
  • They launched from a soccer field up to a heights of 16mi [25km] and reached a height of 6mi [25km] where the helium balloon burst in what is technically known as the stratosphere.
  • * Of Note*
  • Technically they reached the stratosphere, which is 6–30 mi [10–50km] above sealevel.
  • Commercial airliners typically cruise at altitudes of 9–12 km (30,000–39,000 ft)
  • There have been a few sightings and evidence that birds can fly in the lower stratosphere
  • Several Lego toys are constantly flying even higher above the Earth at this very moment aboard the International Space Station as part of an educational outreach effort by NASA and Lego.

Dinosaur feather colors

  • The low down
  • Archaeopteryx is the most ancient bird species known, who spread their wings amid the branches of Late Jurassic trees
  • Archaeopteryx got its name in 1861 based on a lone fossil feather.
  • Significance
  • Examining the original dark trace of feather, scientists turned to a specialized scanning electron microscope in Germany.
  • Checking points along the feather revealed evidence of rod-shaped nubbins like the structures that hold pigments called melanin’s inside the cells of modern feathers.
  • In a procedure that has identified colors on several dinosaurs as well as fossil penguins
  • The pigment-carrying structures, called melanosomes, grouped with modern birds’ black ones instead of the brown or gray ones, or the oddball melanosomes found in penguins
  • * Of Note*
  • There have been questions about whether Archaeopteryx feathers would have been strong enough for the early bird to fly
  • The substance of the feather material was pretty tough stuff due to the melanin, black feathers are typical of this
  • It doesn’t necessarily follow that the feather as a whole had the aerodynamic stiffness for sustained, powered flight
  • Archaeopteryx was probably a pretty clumsy flier or glider.

Old photographic plates reveal new star data

  • The low down
  • Photographic plates preceded photographic film as a means of photography.
  • A light-sensitive emulsion of silver salts was applied to a glass plate
  • Glass plates were far superior to film for research-quality imaging because they were extremely stable and less likely to bend or distort, especially in large-format frames for wide-field imaging
  • There were in wide use by the professional astronomical community as late as the 1990s.
  • Starting in the 1990s, photographic plates were replaced with more sensitive CCDs (charge-coupled devices), which are digital light sensors
  • Significance
  • A century’s worth of astronomical photographic plates have revealed a slew of new variable stars, many of which alter on timescales and in ways never before seen.
  • * Of Note*
  • The discoveries come from a new analysis of the 500,000 plates made by the Harvard College Observatory from the 1880s through the 1980s, covering the whole sky.
  • Scientists are trying to digitize the plate collection, basically using CCDs to image the plates, then applying an algorithm to quantify how bright stars appear and search for variations over time.

  • * Of Note*
  • Earlier this month, the space station fired its thrusters to avoid debris from a 2009 satellite crash between an U.S. and Russian spacecraft.
  • On Jan. 28 the space station had to avoid space junk from the Chinese satellite Fengyun 1C
  • Rocket thrusters on the space station’s fired in a 1-minute, four-second burn to slightly raise the laboratory’s orbit, leaving it on a path that reaches just over 251 miles (404 kilometers)
  • The space station is currently home to a six-man crew that includes three Russians, two Americans and one Dutch astronaut
  • When there is not enough time to plan a dodging maneuver, station astronauts can take shelter inside the Russian Soyuz vehicles that ferry them to and from the station until a piece of space junk has safely zoomed by.
  • The Soyuz capsules, two of which are docked at the station now, each seat three people and can double as lifeboats.

SpaceX Space Station resupply mission resceduled

Do dolphins talk in their sleep?

  • The low down
  • A group of dolphins born in captivity were performing in their shows every day
  • Performing dolphins are primed to learn and remember information
  • During their show music and sounds were played in the background, a new track included music, sea gulls, dolphin whistles and humpback whale calls
  • Significance
  • Because little is known about the nighttime sounds of dolphins researchers had hand hung underwater microphones into the dolphins tank at night
  • One night they discovered that they had produces 25 new sounds that they had never made before
  • When playing back the tapes the researcher found that the new sounds sounded similar to whale songs
  • A new sound track including
  • When analyzed by a computer program the two sounds were very similar
  • When 20 human volunteers were asked to listen to and identify the dolphin nocturnal sounds and humpback whale songs, 76% of the time they classifies the imitations as sounds from real whales
  • Since the dolphins did not make the noises during the day, it indicates that they wanted to wait to practice the sounds at night
  • Of interest is finding out if the dolphins are asleep and dreaming during the time they are making the noises
  • If the dolphins are dreaming it might indicate that, like humans, they etch new information into memories during sleep
  • Next for the research is to take electroencephalogram recordings of the dolphins’ brains at night to determine if they are asleep during the time they make the sounds
  • * Of Note*
  • Before the whale sounds sound track was added to the show the dolphins did not make produces the ‘humpback whale song’
  • Some scientists are not convinced saying that dolphins make so many different sounds that it would be too difficult to quantitatively identify one as an imitation of a particular sound
  • Dolphins are known for mimicry and songbirds rehearse imitations of sounds at night, it is not all that unlikely that if they mimicking dolphins might do the same

Supercritical water and homeless exoplanets

  • The low down
  • The size of a planet can be measured indirectly by analyzing the amount of dimming of a star when the planets transits, and the mass can be identified though ground based measurements of how much gravitational force the planet excerpts on it’s star.
  • From those measurements the density of a planet can be roughly calculated
  • Exoplanets themselves are estimated to outnumber the stars in out galaxy by almost two-to-one
  • One such planet scientist have been analyzing is 55 Cancri, a rocky planet about 7.8 times the size of the Earth, orbiting relatively closely to it’s sun and 40 light-years away from Earth .
  • Significance
  • New observations of a this explanet suggest that about a fifth of the planet’s mass must be made up of light elements and compounds, including water
  • Since this planet if thought to have surface temperatures as high as 4,800 F [2,700 C] this planet is a much weirder planet than originally thought to be
  • The high temperature and pressure conditions on this planet are so extreme the liquids likely exist in a supercritical state
  • Super-critical fluids can best be imagined as liquid-like gases in high pressure and temperature conditions, water becomes supercritical in some steam turbines
  • These superritical fluids could be seeping up from the outer layers of the planets crust, giving scientists an interesting study of a planet
  • * Of Note*
  • Perhaps even stranger is that almost 75% of the exoplants in our galaxy might be ‘free-floating’ planets no longer orbiting a star
  • Some suspected free-floating planets have already been observed and it has been speculated that those free-floating exoplanets would be from gravitationally unstable orbits
  • Recent computer simulations indicate there may be more exotic reasons for the planets to be ejected.
  • One simulation blames end of life stars that expand into red giants litterely pushing their planets into interstellar space
  • Another simulation blames gravitational forces by passing stars, planetary system moving either in or out of a galacy’s dense spiral arms, or interactions with dense molecular clouds
  • The most likely reason for ejection of exoplanets would be from parent stars being gravitationally acted upon in tightly packed star clusters

Running your car with … seaweed?

  • The low down
  • Biofuel is energy from biological material from living or recently living organisms, biomass, that use carbon to grow
  • Using seaweed to create biomass has been a sought after source of biofuel for years as it is full of the sugars needed for the process
  • Seaweed also grows very fast, does not compete for land with crops, and requires no fertilizer or freshwater
  • If a process could be made to meet a certain efficiency it would broaden the biofuels possibilities
  • Significance
  • Unfortunately the gummy cell walls of seaweed make it very hard to get the needed components to make biofuel, making it difficult to compete with other forms of biomass.
  • Researchers have now engineered a bacterium that has the ability to break down those cell walls so that ethanol and other useful products can be gained
  • The process was developed by combining several enzymes that could convert the interior into fuel,
  • The researchers then used the cellular transportation system to inject the combination so that it would secrete the enzyme
  • * Of Note*
  • Currently the bacteria yields approximately 80% of it’s theoretical maximum of ethenol, with further tweaking that number may go even higher
  • Partially broken down product could be used in processes for making nylons or plastics
  • The newly engineered E.coli has no danger of escaping into the environment and consuming seaweed, as it lives best in the human gut, and would likely die in an ocean environment in a short period of time

Crowd sourcing hits earthquakes

  • The low down
  • We mentioned before what social media can do to help the medical community track outbreaks of communicable diseases
  • Seismologists are now getting on the social media tracking band wagon
  • In the past seismologists have relied on sensors in the vicinity of an earthquake and post anecdotal evidence from interviews of people who experienced it
  • Significance
  • There have already been instances where citizen-generated reports have had value in information gathering for earthquakes
  • Scientists had begun to set up websites specifically for people to add what they know about an earthquake to existing data
  • Being a public system seismologists can filter Twitter messages so focus on earthquake related messages, giving researchers real time data as people message about the earthquake
  • Also available to the public are seismic monitors that can attach to building, public or private, to send data via WiFi to designated research facilities
  • In addition to social media there are also Smartphone apps that are available that can be used to turn the phone itself into a vibration sensing device when it is not being carried
  • Other new sensors will become available as interest increases
  • * Of Note*
  • As these new sources of information become available it increases the amount and density of the observational and scientific data
  • More data from earthquakes gives scientists more detailed information about earthquakes, which increases the understanding of them
  • The ability to understand the precursors of an earthquake or even what leads to earthquakes will increase the prediction models

Looking back

  • Jan 27, 1888 : 124 years ago : National Geographic Society founded : The National Geographic Society was established with Gardiner Greene Hubbard as its first president. Two weeks earlier, on 13 Jan 1888, 33 founders in Washington, D.C., U.S.A., had met at the Cosmo Club in Lafayette Square, across from the White House. Their mission was to establish “a society for the increase and diffusion of geographical knowledge.” By Oct 1888, the first National Geographic Magazine was published as a society membership benefit, which continues its monthly issues to the present with photographs and popular articles now expanded from topics of geography and exploration to science, history and world cultures. The society has awarded over 9,000 grants for scientific research, and sponsors a museum and travelling exhibits.
  • Jan 27, 1957 : 55 years ago : Hearts get a portable jump-start](todayinsci.com) : In 1957, an external artificial pacemaker with internal heart electrode is first used. To maintain a patient’s heartbeat rhythm an electrode was sewn to the wall of the heart and connected through the chest to an external desk-top pulse generator. A team of scientists at the University of Minnesota, led by Dr C. Walton Lillehei, made this medical advance. However, such bulky equipment was not a good long-term solution since infection often occurred along the electrode wires, and the device required no interruption in the house electricity. So Dr. Lillehei also initiated research on the use of a small portable external pacemaker for these patients with heart block. This ultimately led to the development of the billion-dollar pacemaker industry.
  • Jan 30, 1958 : 54 years ago : Please be careful stepping on or off the platform](todayinsci.com) : Although the first moving sidewalk was a whopping 119 years ago, at the World’s Fair in Chicago in 1893. The first two-way, moving sidewalk, 1,425 feet long, was put in service at Love Field Air Terminal in Dallas, TX. It consisted of three loops. In each loop a continuous rubber carpet was attached to a continuous train of wheeled pallets, flexibly interconnected so they could follow vertical or horizontal curves as required. It was known not only as a moving sidewalk, but also as a passenger conveyor. more icon

Questions about the sun

  • If the sun can’t fuse gold and such why are they there?
  • Do scientists take these into account with calculating life of the sun?
  • Do they account for them with the weight of the sun?
  • Should we look to Mercury Venus for heavier elements?
  • Formation of the Solar System
  • Throughout the galaxy there are dust clouds containing mostly Hydrogen and heavier elements
  • The heavier elements are from the cores of Type II super nova, when they explode they seed the surrounding areas with those heavier elements
  • The cloud will start contracting, eventually forming a star with a surrounding dust cloud
  • The Sun
  • The sun is 4.5 billion year old main sequence star
  • It has converted about half of the hydrogen in its core into helium, so it still has about 5 billion years before the hydrogen runs out.
  • Each second, more than four million metric tons of matter are converted into energy within the Sun’s core, producing neutrinos and solar radiation
  • The sun manufactures elements from lighter ones in the process of nuclear fusion. Helium is a byproduct of nuclear fusion, and beryllium, lithium, boron, and other atoms are part of the ordinary fusion process.
  • Planets
  • The inner Solar System, the region of the Solar System inside 4 AU, was too warm for volatile molecules like water and methane to condense, so the planetesimals that formed there could only form from compounds with high metals (like iron, nickel, and aluminium) and rocky silicates.
  • These compounds are quite rare in the universe, comprising only 0.6% of the mass of the nebula, so the terrestrial planets could not grow very large
  • The composition of the inner planets are very similar, as are the compositions of the asteroids in the asteroid belt
  • * Of Note*
  • Mining other inner planets for metals might be feasible if we were able to safely travel there and back, and for less money that would require to aquire it on Earth
  • Another reason to mine other inner planets would be to increase the supplies of rare metals on Earth

From Twitter : First Solar Cell to break the rules?

  • A Twitter follower pointed out this story
  • The low down
  • Researchers from the National Renewable Energy Laboratory (NREL) have reported the first solar cell that produces a photocurrent that has an external quantum efficiency greater than 100 percent when photoexcited with photons from the high energy region of the solar spectrum.
  • Quantum efficiency for photocurrent, usually expressed as a percentage, is the number of electrons flowing per second in the external circuit of a solar cell divided by the number of photons per second of a specific energy (or wavelength) that enter the solar cell
  • Significance
  • The company’s tiny solar cells, each a dot the size of a ballpoint pen tip, have been validated to convert 41 percent of solar energy to electricity
  • They can grow a tiny semiconductor on a substrate and then a machine transfers those cells to a wafer.
  • Additional layers are automatically added to the wafer so that a very efficient, triple-junction solar cell is constructed
  • Quantum dots, by confining charge carriers within their tiny volumes, can harvest excess energy that otherwise would be lost as heat – and therefore greatly increase the efficiency of converting photons into usable free energy.
  • The semiconductor printing technique can be used for many applications, including improving LED lighting performance, better hard drives, or sensors for medical device.
  • The company that was chosen to build concentrating photovoltaic (CPV) collector that uses lenses to concentrate light 1,000 times onto its tiny solar cells.
  • The mechanism for producing a quantum efficiency above 100 percent with solar photons is based on a process called Multiple Exciton Generation (MEG)
  • Multiple Exciton Generation (MEG) is where a single absorbed photon of appropriately high energy can produce more than one electron-hole pair per absorbed photon.
  • The first built concentrating photovoltaic (CPV) collector that uses lenses to concentrate light 1,000 times onto its tiny solar cells
  • Photons of different colors have different amounts of energy. In the visible spectrum, reds and oranges have less energy, while blues, violets, and ultraviolet photons carry progressively more.
  • When high-energy photons hit a semiconducting material in a solar cell, they give up this energy to the semiconductor’s electrons, exciting them from a static position so that they are able to conduct.
  • In many cases, high-energy photons—violets and ultraviolets—carry far more energy than is needed to give electrons the nudge to conduct. But this excess energy is lost as heat.
  • These solar cells captures some of the excess energy in sunlight normally lost as heat.
  • * Of Note*
  • The key in making the device, Nozik says, was coming up with a recipe for chemically synthesizing and then processing quantum dots.
  • When synthesized, the dots—which are clusters of lead and selenium about 5 nanometers in diameter—end up decorated with long organic molecules that prevent separate dots from clumping together.
  • The company’s target to build a system that generates electricity at under 10 cents per kilowatt hour

Smallest Black hole

  • The low down
  • Black holes reside at the centres of galaxies and swallow everything that falls into their gravitational clutches such that nothing, not even light, can escape.
  • The largest supermassive black holes, capable of swallowing our Solar System whole several times over, were reported just last week
  • Significance
  • Scientists have now found a black hole that could represent the lower boundary for a black hole’s mass at just three solar masses.
  • The distinct pattern of X-ray emission, which resembles the pattern printed on an electrocardiogram in response to a heartbeat
  • * Of Note*
  • That there are only two possibilities to explain the differences: either the new source is farther away or its mass is lower
  • There is a limit to how distant it could be as it would be very unlikely to have it lying outside our Galaxy.
  • In addition the fact that its ‘heart’ beats faster is compatible with a lower mass

Plant-eating dinosaur discovered in Antarctica

  • The low down
  • For the first time, the presence of large bodied herbivorous dinosaurs, Sauropoda, in Antarctica has been recorded.
  • Sauropoda is the second most diverse group of dinosaurs, with more than 150 recognized species.
  • Significance
  • The team’s identification of the remains of the sauropod dinosaur suggests that advanced titanosaurs (plant-eating, sauropod dinosaurs) achieved a global distribution at least by the Late Cretaceous
  • The Cretaceous Period spanned 99.6–65.5 million years ago, and ended with the extinction of the dinosaurs.
  • A detailed description of an incomplete middle-tail vertebra its distinctive ball and socket articulations, lead the authors to identify it as an advanced titanosaur.
  • * Of Note*
  • Until now, remains of sauropoda had been recovered from all continental landmasses, except Antarctica.
  • Other important dinosaur discoveries have been made in Antarctica in the last two decades.

SPACECRAFT UPDATE

  • * Last time on SciByte*
  • SciByte 22-Nov 22
  • SciByte 23-Nov 30
  • The low down
  • Launch Date: Nov. 26, 2011
  • On Earth it weights roughly 1,982 lbs [899 kg]
  • On Mars is will weight roughly 743 lbs [337 kg]
  • Mars it will weigh 3/8 that due to the lower gravity)
  • That first of six planned course adjustments had originally been scheduled for Nov. 26. The correction maneuver will not be performed until later in December or possibly January.
  • Landing scheduled for : Aug 6, 2012
  • * Of Note*
  • Already 32 million miles from Earth on its interplanetary trek to Mars, the Curiosity rover has begun collecting useful scientific data about the radiation conditions that astronauts would encounter on the way to the red planet.
  • The Radiation Assessment Detector, an instrument mounted the rover, has begun obtaining measurements on energetic particles penetrating the Mars Science Laboratory spacecraft.
  • The device, about the size of a coffee can and weighing 3.8 pounds, was powered up and started gathering data on Dec. 6, some two weeks ahead of schedule. It will downlink data every 24 hours.
  • Scientists are seeing, even inside the spacecraft, about four times higher doses of radiation than the baseline we measured on the launch pad.
  • RAD was designed for the science mission to characterize radiation levels on the surface of Mars, but an important secondary objective is measuring the radiation on the almost nine-month journey through interplanetary space, to prepare for future human exploration

SCIENCE CALENDER

Looking back

  • Dec 25 1758 – 253 years ago – predicted return of Halley’s comet : Clear records of the comet’s appearances were made by Chinese, Babylonian, and medieval European chroniclers dating back to 240 BC. It was not until 1705 that Edmund Halley hypothesized that a number of the observation were the same comet. He predicted it would return in 75.5 years and in 1758 it was first sighted by German farmer and amateur astronomer, Johann Georg Palitzsch. Halley’s orbital period over the last three centuries has been between 75 and 76 years, though it has varied between 74 and 79 years. It also has a retrograde orbit, orbiting in the opposite direction of the planets. It’s shape if vaguely resembles a peanut and measures 9.3 x 4.9 x 4.9 mi [15x8x8 km]. Halley’s comet last appeared in the inner Solar System in 1986 and will next appear in mid–2061.
  • Dec 22 1938 – 73 years ago – First coelacanth (re)discovered : Marjorie Courtenay-Latimer, curator of the museum of East London, South Africa, discovered the fish among the catch of a local fisherman. She spotted an unusual 5-ft fish in his “trash” fish pile, believed to have been extinct since the end of the Cretaceous period (145.5 to 65.5 million years) The coelacanth was pale mauvy-blue with iridescent silver markings, and they can grow up to 5.9 ft [1.8 m.] The heart of the coelacanth is shaped differently than most modern fish and its structure is that of a straight tube. The coelacanth braincase is 98.5% filled with fat; only 1.5% of the braincase actually contains any brain.Since 1938, Latimeria chalumnae have been found in the Comoros, Kenya, Tanzania, Mozambique, Madagascar, and in iSimangaliso Wetland Park, Kwazulu-Natal in South Africa. YouTUBE Video
  • Dec 23 1986 – 25 years ago – Voyager – first non-stop, round- the- world flight without refueling : It was piloted by Dick Rutan and Jeana Yeager and took off from Edwards Air Force Base in California on December 14, 1986. It flew easterly 24,986 mi [40,211 lm] in a little over 9 days, 3 minutes and on Dec 23 in completed the first non-stop, round- the- world flight without refueling. A cockpit was only roughly the size of a phone booth, which complicated the flight and sleep rotation of the pilots. It returned safely to Edwards Air Force Base in California after travelling 24,986 miles in 216 hours, at an average speed of 115.8 mph.This has since been accomplished only one other time, by Steve Fossett in the Global Flyer.

Polly want an explanation for how parrots talk

  • The low down
  • Parrots have neither lips nor teeth, but that doesn’t stop them from producing dead-on imitations of human speech
  • Significance
  • Part of the reason is that, like humans, parrots use their tongues to form sounds
  • Scientists took x-ray movies of monk parakeets
  • Parrots use their mobile, muscular tongues to explore their environment and manipulate food
  • Those capable organs also help parrots utter greetings in words that even humans can understand.

Learning by the Matrix/Chuck way

  • The low down
  • Pictures gradually build up inside a person’s brain, appearing first as lines, edges, shapes, colors and motion in early visual areas
  • The brain then fills in greater detail
  • New research in the journal Science suggests it may be possible to use brain technology to learn to play a piano, reduce mental stress or hit a curve ball with little or no conscious effort
  • Significance
  • Researchers could use decoded functional magnetic resonance imaging (fMRI) to induce brain activity patterns to match a previously known target state and thereby improve performance on visual tasks
  • Think of a person watching a computer screen and have brain patterns modified to match those of a high-performing athlete or modified to recuperate from an accident or disease
  • This research is a novel learning approach sufficient to cause long-lasting improvement in tasks that require visual performance
  • None of these studies directly addressed the question of whether early visual areas are sufficiently plastic to cause visual perceptual learning
  • * Of Note*
  • The approached worked even when test subjects were not aware of what they were learning
  • The decoded neurofeedback method might be used for various types of learning, including memory, motor and rehabilitation
  • On the flip side the neurofeedback mechanism could just as soon be used for purposes of hypnosis or covert mind control

SPACECRAFT UPDATE

DAWN Spacecraft reachest closts orbit to the asteroid Vesta

  • Vesta:
  • Discovered: March 29, 1807 by Heinrich Wilhelm Olbers of Germany (fourth asteroid discovered)
  • Dimensions: About 578 by 560 by 458 kilometers (359 by 348 by 285 miles)
  • Shape: Nearly spheroid, with a massive chunk out of the south pole
  • Rotation: Once every 5 hours, 20 minutes
  • About the length of Arizona, it appears to have a surface of basaltic rock – frozen lava – which oozed out of the asteroid’s presumably hot interior shortly after its formation 4.5 billion years ago, and has remained largely intact ever since.
  • DAWN:
  • Launch Date : Sep 27, 2007
  • Mission will go through through July 2015
  • Framing Camera (FC) : Scientific imaging system of the Dawn Mission to the two complementary protoplanets, 1 Ceres and 4 Vesta.
  • Visible & Infrared Spectrometer (VIR) : Accomplishes the Dawn mission’s scientific and measurement objectives of producing spectral images. NASA’s Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta today

  • Dec 15 1612 – 399 years ago – A telescope meets the Andromedo galaxy : [Simon Marius](https://en.wikipedia.org/wiki/Simon_Marius, namer of Jupiter’s 4 inner satellites, is first to observe Andromeda galaxy through a telescope. Andromeda is the nearest spiral galaxy to the Milky Way, but not the closest galaxy overall. The Persian astronomer Abd al-Rahman al-Sufi wrote a tantalizing line about it in his Book of Fixed Stars around 964, describing it as a “small cloud”.
  • **Dec 14 1807 – 204 years ago – Meteorite gets scienced ** : In Weston, (now called Easton) Connecticut at 6:30 am, a meteorite was seen with an aparent size of 2/3 the size of the moon. Eyewitnesses reported three loud explosions, as it fell and broke apart to fall in at least six locations. This meteor became the first to fall in the New World to be documented, collected, and chemically analyzed and received much attention in the national and international press. The largest and only unbroken specimen weighing in at 36.5 pounds (16.5 kilograms) was recovered and made a hole 5 ft long and 4.5 ft wide (1.5 m long and 1.4 m wide) now resides within the oldest collection of meteorites in the United States. Out of the approximately 350 pounds of the meteorite that fell on the town of Weston, less than 50 pounds can now be accounted for. Yale Peabody Museum – Weston Meteorite
  • **Dec 17 1903 – 108 years ago – The Wright brother fly ** : In 1903, the first powered flight was achieved by the [Wright brothers](https://en.wikipedia.org/wiki/Wright_brothers#Flights in the Kitty Hawk, at Kill Devil Hill, North Carolina. That morning, the biting cold wind had a velocity of 22 to 27 miles an hour. As ten o’clock arrived, the Wrights decided, nevertheless, to get the machine out and attempt a flight. Orville Wright launched from a track, taking off into the wind. The aircraft covered 120 feet, aloft for 12 seconds. Thus for the first time, a machine carrying a man had raised itself by its own power into the air in full flight, had sailed forward without reduction of speed and had finally landed at a point as high as that from which it started.

We take a look at the Curiosity Rover launching this week, Europa’s water, bugs, Voyager, telescopes and as always take a peek back into history and up in the sky this week.

Too much out there is just plain distraction, why can’t we have our cake and eat it too? There are a lot of interesting things going on out there in science, but getting to the interesting bits without all the hype you get from major media outlets is a trick we at Jupiter Broadcasting are hoping to pull off.

Why are flies attracted to beer?

  • The low down
  • Insects use their taste system to glean important information about the quality and nutritive value of food sources
  • Taste becomes important only after the fly makes physical contact with food
  • A fly first locates food sources using its odor receptors – crucial for its long-range attraction to food
  • Then, after landing on food, the fly uses its taste system to sample the food for suitability in terms of nutrition and toxicity
  • Significance
  • Flies are attracted to beer because they detect glycerol, a sweet-tasting compound that yeasts make during fermentation.
  • A receptor (a protein that serves as a gatekeeper) that is associated with neurons located in the fly’s mouth-parts is instrumental in signaling a good taste for beer
  • * Of Note*
  • How do you get information from the chemical environment to the brain – not just in flies but other insects as well

Amoeba-Sized Insect

  • The low down
  • The fairy wasp (Megaphragma mymaripenne), which at a mere 200 micrometers in length is one of the world’s smallest animals [roughly 2 strands of human hair / or 10 could fit between between pins in DIP]
  • Roughly the size of an amoeba, the wasp shrink so small that it can avoid most predators and invade the eggs of other insects
  • When the scientist compared the neurons of adult and pupae fairy wasps, he discovered that more than 95% of adult neurons lack a nucleus.
  • Significance
  • suggest that while a complete set of neurons is needed to grow, far less are required to live

Migrating Dinosaurs

  • The low down
  • studying chemical variations in the teeth of the chewing-challenged sauropod
  • When animals drink water, the oxygen in that water gets incorporated into the blood stream and eventually into tooth enamel
  • water from a mountain tarn and water from a lowland swamp will have different amounts of a particular form, or isotope, of oxygen that has two extra neutrons in its nucleus
  • Significance
  • oxygen isotopes extracted from the tooth enamel of eight fossils remains from the western United States, and then compared the enamel isotope levels to those of minerals found in nearby sediments
  • isotopic variation suggests, that they were moving around

Snake Oil
  • The low down
  • snakes naturally enlarge their own hearts by some 40 percent in two to three days after eating one of their huge but rare meals
  • A mix of compounds called fatty acids identified in pythons can spur an exercise-like boost in the size of mouse hearts
  • three fatty acids identified in the blood of Burmese pythons boosted the mass of a heart chamber in lab mice by 10 percent in just a week
  • Significance
  • Enlarging heart tissue can be a danger sign for humans
  • the growth seen in the mice looks more like an athlete’s healthful heart growth than a heart disease patient’s worrisome one
  • These ubiquitous compounds perform a variety of functions in reptiles and humans alike. Just the right mix of three of them — myristic, palmitic and palmitoleic acid — turns out to trigger a quick upsizing in heart muscle cells
  • many questions remain about how the snakes’ fatty acids actually work to trigger heart muscle cells to bulge

Story of a Molten Asteroid

  • The low down
  • Lutetia and its asteroid cousins are thought to be relics from the early solar system
  • rocky fossils that have recorded a history of the solar system’s early days in their pits and fractures
  • In July 2010, the European Space Agency’s Rosetta spacecraft flew within 3,200 kilometers of Lutetia, peered at the asteroid and attempted to read its stony story.
  • Images from the OSIRIS camera reveal that parts of Lutetia’s surface are around 3.6 billion years old. Other parts are young by astronomical standards, at 50–80 million years old.
  • Astronomers estimate the age of airless planets, moons, and asteroids by counting craters.
  • Lutetia’s weak gravity tugged on Rosetta. The slight change in Rosetta’s path was reflected in radio signals received back at Earth
  • Significance
  • Scientists now think it is a leftover planetary seed, booted into the main belt
  • Lutetia turns out to have one of the highest densities of any known asteroid: 3400 kg per cubic metre.
  • The density implies that Lutetia contains significant quantities of iron, but not necessarily in a fully formed core.
  • The only explanation appears to be that Lutetia was subjected to some internal heating early in its history but did not melt completely and so did not end up with a well-defined iron core.

Looking back this week
  • Nov 06, 1572 – 439 years ago : Tycho’s Supernova – A supernova was first noted in the W-shaped constellation of Cassiopeia but was seen by many observers throughout Europe and in the Far East. For two weeks it was brighter than any other star in the sky and visible in daytime. By month’s end, it began to fade and change colour, from bright white to yellow and orange to faint reddish light. It was visible to the naked eye for about 16 months
  • Nov 08, 1895 – 116 years ago : X-rays – Wilhelm Röntgen discovered X-rays during an experiment at Würzburg University
  • Nov 07, 1908 – 103 years ago : Single atom – Prof. Ernest Rutherford announced in London that he had isolated a single atom of matter
  • Nov 07, 1918 – 93 years ago : Goddard rocket – Goddard demonstrated a tube-launched solid propellant rocket, using a music stand as his launching platform,. Goddard began work for the Army in 1917 to design rockets to aid in the war effort.
  • Nov 04–05, 1922 – 89 years ago : Tutankhamen’s tomb – The entrance to King Tutankhamen’s tomb was discovered in Egypt in the Valley of the Kings where the English archaeologist Howard Carter had been making extended excavations. One of Carter’s labourers stumbled upon a stone step, the first step in a sunken stairway that ran down into the rock. Howard Carter excavated a further 11 steps and exposed a large part of a plastered and sealed doorway to Tutankhamun’s tomb in the Valley of the Kings near Luxor, Egypt. The tomb was the most complete ancient Egyptian royal tomb ever found.
  • Nov 07, 1940 – 71 years ago : Tacoma Narrows Bridge collapse – at approximately 11:00 am, the first Tacoma Narrows suspension bridge collapsed due to wind-induced vibrations. Situated on the Tacoma Narrows in Puget Sound, near the city of Tacoma, Washington, the bridge had only been open for traffic a few months. Video of Tacoma Narrows Bridge Collapse “Gallopin’ Gertie”
  • Nov 02, 1947 – 64 years ago : Spruce Goose – Howard Hughes piloted his huge wooden airplane, known as the Spruce Goose on its only flight, which lasted about a minute over Long Beach Harbor in California. It was the first test of a U.S. plane with eight engines. Wing span was 319 feet, 11 inches. Originally conceived by Henry J. Kaiser, a steelmaker and builder of Liberty ships, the aircraft was designed and constructed by Hughes and his staff. The original proposal for the enormous, 400,000-pound wooden flying boat, with its spectacular 320-foot wingspan, came from the U.S. government in 1942. The entire airframe and surface structures are composed of laminated wood (primarily birch, not spruce).
  • Nov 03, 1957 – 54 years ago : Laika – Sputnik 2 was launched, with the first live animal sent into space – a Siberian husky dog, Laika (“barker” in Russian). By design, the craft which was built in only 4 weeks. Biological data, the first data of its kind, was transmitted back to Earth while she lived. The data showed scientists how Laika was adapting to space – information important to the imminent planned manned missions. The 508-kg satellite remained in orbit 162 days. The true cause and time of Laika’s death was not made public until 2002, Laika likely died within hours after launch from overheating.
  • Nov 05, 1963 – 48 years ago : Vikings in America – Archaeologists found Viking ruins in Newfoundland predating Columbus by 500 years. Leif Ericson, Icelandic explorer, second son of Eric the Red, is believed by most historians to have been the first European to reach the North American mainland.
