International and Private Space Travel

  • India’s Mars Orbiter Mission
  • India’s first ever Mars probe ‘MOM’ successfully fired its main engine on Dec. 1 to begin its nearly yearlong momentous voyage to Mars
  • ISRO’s engineers devised a procedure to get the spacecraft to Mars on the least amount of fuel via six “Midnight Maneuver” engine burns over several weeks – and at an extremely low cost
  • This maneuver increases the ship’s velocity and gradually widens the ellipse eventually raising the apogee of the six resulting elliptical orbits around Earth that eventually injects MOM onto the Trans-Mars trajectory

  • Chinese Lunar Lander
  • China had a successful touchdown of the Chang’e-3 probe with the ‘Yutu’ rover on the surface of the Moon on Dec. 14
  • They landed on the lava filled plains of the Bay of Rainbows occurred at about 8:11 am EST or 9:11 p.m. Beijing local time
  • Barely seven hours after the Chang’e-3 mothership touched down on Sunday, Dec. 15, the six wheeled ‘Yutu’, or Jade Rabbit, rover drove straight off a pair of ramps at 4:35 a.m. Beijing local time
  • SciByte 113 | Freshwater Aquifers & Brain Plasticity (December 17, 2013)
  • Bigelow Aerospace’s | Genesis, Inflatable Space Station Modules
  • On Jan 11 NASA announced they have awarded a $17.8 million contract to Bigelow to provide a new inflatable module for the ISS, making it the first privately built module to be added to the space station
  • The outer shell of their module is soft, as opposed to the rigid outer shell of current modules at the ISS, Bigelow’s inflatable modules are more resistant to micrometeoroid or orbital debris strikes it uses multiple layers of Vectran, a material which is twice as strong as Kevlar
  • The company wants to launch and link up several of its larger expandable modules to create private space stations, which could be used by a variety of clients.
  • SciByte 77 | Breath Analysis & Large Structures (January 15, 2013)
  • SpaceX | Geostationary Orbit
  • The Dec 3 liftoff at 5:41 p.m. EST (2241 GMT) marked SpaceX\’s first entry into the large commercial satellite market and its first launch into a geostationary transfer orbit needed for such a mission.
  • Being able to launch into this new orbit will let SpaceX compete against Europe and Russia to haul large telecommunications satellites into orbit.
  • This launch also marks the second of three certification flights needed to certify the Falcon 9 to fly missions for the U.S. Air Force under the Evolved Expendable Launch Vehicle (EELV) program
  • When Falcon 9 is certified, SpaceX will be eligible to compete for all National Security Space (NSS) missions

New Multiple Sclerosis Treatment

  • Scientists have identified a set of compounds that may be used to treat multiple sclerosis (MS) in a new way
  • The newly identified compounds, a Parkinson\’s disease drug called benztropine, was highly effective in treating a standard model of MS in mice, both alone and in combination with existing MS therapies
  • The compounds boost a population of progenitor cells that can in turn repair MS-damaged nerve fibers
  • Another Study SciByte Recently Looked At
  • In trial, a MS patients\’ own specially processed white blood cells were used to stealthily deliver billions of myelin antigens into their bodies so their immune systems would recognize them as harmless and develop tolerance to them
  • SciByte 97 | CoQ10 & Smart LEGO – Multiple Sclerosis Treatment | June 11, 2013
  • SciByte Does Not Approve Self Medicating
  • Benztropine is a drug with dose-related adverse side effects, and has yet to be proven effective at a safe dose in human MS patients
  • Multiple Sclerosis (MS)
  • MS currently affects more than half a million people in North America and Europe, and more than two million worldwide
  • The precise cause isunknown, but certain infections and a lack of vitamin D are thought to be risk factors
  • In MS, immune cells known as T cells infiltrate the upper spinal cord and brain, which causes inflammation and ultimately the loss of an insulating coating called myelin on some nerve fibers
  • As nerve fibers lose this myelin coating, they lose their ability to transmit signals efficiently, and in time may begin to degenerate
  • Current therapies aim to suppress the immune attack that demyelinated nerve fibers. But they are only partially effective and are apt to have significant adverse side effects
  • The New Study
  • Aims at restoring a population of progenitor cells called oligodendrocytes
  • These cells normally keep the myelin sheaths of nerve fibers in good repair and in principle could fix these coatings after MS damages them
  • In MS oligodendrocyte decline sharply in number, due to a still-mysterious problem with the stem-like precursor cells that produce them
  • The team screened a library of about 100,000 diverse compounds for any that could potently induce OPCs to mature or \”differentiate.\”
  • Several compounds scored well but benztropine, had already been well characterized and was already FDA-approved for treating Parkinson\’s disease
  • Tests show benztropine had a powerful ability to prevent autoimmune disease and also was effective in treating it after symptoms had arisen
  • Benztropine on its own worked about as well as existing treatments, it also showed a remarkable ability to complement these existing treatments
  • In Conjunction With Current Therapies
  • The two first-line immunosuppressive therapies are interferon-beta and fingolimod
  • Adding even a suboptimal level of benztropine allowed to cut the dose of fingolimod by 90% for the same effect as a normal dose
  • The reduction could translate into a big reduction in potentially serious side effects
  • The Test
  • Researchers confirmed that benztropine works against disease in this mouse model by boosting the population of mature oligodendrocytes
  • This allowed the oligodendrocytes to restore the myelin sheaths of damaged nerves even while the immune continues to attack
  • The benztropine-treated mice showed no change in the usual signs of inflammation, yet their myelin was mostly intact, suggesting that it was probably being repaired as rapidly as it was being destroyed
  • Researchers hope to learn more about how its molecular structure might be optimized for this purpose

Ancient Comet Strike Evidence

  • Comet fragments have not been found on Earth before except as microscopic sized dust particles in the upper atmosphere and some carbon-rich dust in the Antarctic ice.
  • Now the first ever evidence of a comet entering Earth\’s atmosphere and exploding, raining down a shock wave of fire which obliterated every life form in its path, has been discovered
  • Comet Strike?
  • The comet entered Earth\’s atmosphere above Egypt about 28 million years ago
  • As it entered the atmosphere, it exploded, heating up the sand beneath it to a temperature of about 2,000C [3,632F]
  • That resulted in the formation of a huge amount of yellow silica glass which lies scattered over a 6,000 sq km [2,316 sq mi] area in the Sahara
  • One specimen of the glass, polished by ancient jewellers, is in Tutankhamun\’s brooch with its striking yellow-brown scarab
  • Impact Produced Microscopic Diamonds
  • The impact of the explosion also produced microscopic diamonds
  • A mysterious black pebble found years earlier by an Egyptian geologist in the area of the silica glass
  • After conducting highly sophisticated chemical analyses on this pebble it was concluded that it represented the very first known hand specimen of a comet nucleus
  • The team have named the diamond-bearing pebble \”Hypatia\” in honour of the first well known female mathematician, astronomer and philosopher, Hypatia of Alexandria

Russian Meteor

— CURIOSITY UPDATE —

  • Examination of the Martian atmosphere by NASA\’s Curiosity Mars rover confirms that some meteorites that have dropped to Earth really are from the Red Planet
  • Exact Measurements
  • A key new measurement of the inert gas argon in Mars\’ atmosphere by Curiosity\’s laboratory provides the most definitive evidence yet of the origin of Mars meteorites while at the same time providing a way to rule out Martian origin of other meteorites
  • The new measurement is a high-precision count of two forms of argon — argon-36 and argon-38 — accomplished by the Sample Analysis at Mars (SAM) instrument inside the rover.
  • These lighter and heavier forms, or isotopes, of argon exist naturally throughout the solar system
  • On Mars the ratio of light to heavy argon is skewed because much of that planet\’s original atmosphere was lost to space
  • The lighter form of argon was taken away more readily because it rises to the top of the atmosphere more easily and requires less energy to escape
  • That left the Martian atmosphere relatively enriched in the heavier isotope, argon-38
  • Past analyses by Earth-bound scientists of gas bubbles trapped inside Martian meteorites had already narrowed the Martian argon ratio to between 3.6 and 4.5
  • Measurements by NASA\’s Viking landers in the 1970s put the Martian atmospheric ratio in the range of four to seven
  • The new SAM direct measurement on Mars now pins down the correct argon ratio at 4.2
  • What\’s Next?
  • The Curiosity measurements do not directly measure the current rate of atmospheric escape
  • NASA\’s next mission to Mars, the Mars Atmosphere and Volatile Evolution Mission (MAVEN), is designed to do so, which is being prepared for a launch-opportunity period that begins on Nov. 18

Show Notes:

\”Functional Cure\” in an HIV-Infected Infant

  • A team of researchers from Johns Hopkins Children\’s Center has described the first case of a so-called \”functional cure\” in an HIV-infected infant
  • The infant described in the report underwent remission of HIV infection after receiving antiretroviral therapy (ART) within 30 hours of birth
  • Natural Viral Suppression
  • Natural viral suppression without treatment is an exceedingly rare phenomenon observed in less than half a percent of HIV-infected adults
  • HIV experts have long sought a way to help all HIV patients achieve elite-controller status
  • \”Elite controllers,\” whose immune systems are able to rein in viral replication and keep the virus at clinically undetectable levels
  • Functionally Cured
  • \”Functionally cured,\” a condition that occurs when a patient achieves and maintains long-term viral remission without lifelong treatment and standard clinical tests fail to detect HIV replication in the blood
  • A functional cure occurs when viral presence is so minimal, it remains undetectable by standard clinical tests, yet discernible by ultrasensitive methods
  • Sterilizing Cure
  • A sterilizing cure-a complete eradication of all viral traces from the body
  • A single case of sterilizing cure has been reported so far in an HIV-positive man treated with a bone marrow transplant for leukemia.
  • The bone marrow cells came from a donor with a rare genetic mutation of the white blood cells that renders some people resistant to HIV
  • Such a complex treatment approach, however, HIV experts agree, is neither feasible nor practical for the 33 million people worldwide infected with HIV
  • Medical Details
  • The child described was born to an HIV-infected mother and received combination antiretroviral treatment beginning 30 hours after birth.
  • A series of tests showed progressively diminishing viral presence in the infant\’s blood, until it reached undetectable levels 29 days after birth
  • 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
  • Test for HIV-specific antibodies-the standard clinical indicator of HIV infection-also remained negative
  • Antiviral Treatment
  • Investigators say the prompt administration of antiviral treatment likely led to this infant\’s cure by halting the formation of hard-to-treat viral reservoirs
  • Prompt antiviral therapy in newborns that begins within days of exposure may help infants clear the virus and achieve long-term remission without lifelong treatment by preventing such viral hideouts from forming in the first place
  • Dormant cells are responsible for re-igniting the infection in most HIV patients within weeks of stopping therapy
  • Researchers say they believe this is precisely what happened in the child described in the report
  • What This Means
  • Currently, high-risk newborns-those born to mothers with poorly controlled infections or whose mothers\’ HIV status is discovered around the time of delivery-receive a combination of antivirals at prophylactic doses to prevent infection for six weeks and start therapeutic doses if and once infection is diagnosed
  • This particular case may change the current practice because it highlights the curative potential of very early ART
  • Investigators caution they don\’t have enough data to recommend change right now to the current practice of treating high-risk infants
  • This infant\’s case provides the rationale to start proof-of-principle studies in all high-risk newborns
  • The next step is to find out if this is a highly unusual response to very early antiretroviral therapy or something we can actually replicate in other high-risk newborns
  • Researchers say preventing mother-to-child transmission remains the primary goal as they already have proven strategies that can prevent 98 percent of newborn infections by identifying and treating HIV-positive pregnant women

A Star That’s Almost as Old as the Universe

  • Results from a new study show that a metal-poor star located merely 190 light-years from the Sun is 14.46+-0.80 billion years old, which implies that the star is nearly as old as the Universe
  • Such metal-poor stars are important to astronomers because they set an independent lower limit for the age of the Universe and can be used to corroborate age estimates inferred by other means
  • Amount of Metal vs Age of Star
  • Metal-poor stars can be used to constrain the age of the Universe because metal-content is typically a proxy for age
  • Heavier metals are generally formed in supernova explosions, which pollute the surrounding interstellar medium.
  • Stars subsequently born from that medium are more enriched with metals than their predecessors with each successive generation becoming increasingly enriched
  • The reliability of the age determined is likewise contingent on accurately determining the sample’s metal content, and is likewise contingent on the availability of a reliable distance
  • Analyses of globular clusters and the Hubble constant yielded vastly different ages, by billions of years, for the Universe, the discrepant ages stemmed partly from uncertainties in the cosmic distance scale
  • HD 140283
  • HD 140283 exhibits less than 1% the iron content of the Sun, which provides an indication of its sizable age.
  • Based on the microwave background and the Hubble constant, it must have formed soon after the big bang
  • This star had been used previously to constrain the age of the Universe, but uncertainties tied to its estimated distance (at that time) made the age determination somewhat imprecise
  • Scientists were recently also to obtain a new and improved distance for HD 140283 using the Hubble Space Telescope (HST), namely via the trigonometric parallax approach
  • From that data the distance uncertainty for HD 140283 was significantly reduced by comparison to existing estimates, thus resulting in a more precise age estimate for the star
  • The age of HD 140283 does not conflict with the age of the Universe, 13.77 ± 0.06 billion years, within the errors
  • This study reaffirms that there are old stars roaming the solar neighborhood which can be used to constrain the age of the Universe

— SPACECRAFT UPDATE—

SpaceX – Dragon Space Station Resupply Mission Glitch

  • The Glitch
  • The problem cropped up immediately following Dragon\’s separation from the rocket upper stage, nine minutes into the flight.
  • Three of the four sets of thrusters on the company\’s unmanned Dragon capsule did not immediately kick in, delaying the release of the solar panels.
  • The problem may have been caused by a stuck valve or a line blockage
  • Dragon\’s twin solar wings swung open two hours later than planned, an hour later, the Dragon was raised with the thrusters to a safe altitude.
  • Working Towards the Solution
  • SpaceX worked to bring up the idled thrusters and keep the capsule on track
  • The Dragon is equipped with 18 thrusters, divided into four sets, and can maneuver adequately even with some unavailable.
  • The capsule is designed to return to Earth with just two good sets of thrusters and, in \”a super worst case situation,\” conceivably just one although it would be \”a bit of a wobbly trip.\”
  • If SpaceX and NASA had determined that more time was needed to gain confidence that Dragon could safely carry out an attempt the Dragon could have stayed in orbit for several additional months if needed
  • By late Saturday afternoon sufficient recovery work had been accomplished to warrant NASA, ISS and SpaceX managers to give the go-ahead for the Dragon to rendezvous with the station early Sunday morning, March 3.
  • Capture
  • The capsule was captured 5:31 am EST (1031 GMT) on Sunday, March 3
  • More than 1 ton of space station supplies aboard this Dragon, which included some much-needed equipment for air purifiers
  • It is scheduled to spend more than three weeks at the space station before being cut loose by the crew
  • Despite the one-day docking delay, the Dragon unberthing and parachute assisted return to Earth will still be the same day as originally planned on March 25.
  • History
  • This has been the first serious trouble to strike a Dragon in orbit, none of the four previous unmanned flights had any thruster issues
  • On the previous flight in October, one of nine first-stage engines on the Falcon rocket shut down too soon, on this flight it performed \”really perfectly\” and that the thruster problem was isolated to the Dragon
  • Future Re-Supply Missions
  • SpaceX plans to launch its next Dragon to the station in late fall.
  • SpaceX says it has 50 launches planned-both NASA missions and commercial flights-totaling about $4 billion in contracts
  • NASA also has a $1.9 billion resupply contract for the station with Orbital Sciences Corporation, which will launch the first test flight of its Antares rocket from a base in Virginia in the coming weeks

— CURIOSITY UPDATE —

  • The \’Glitch\’
  • The spacecraft remained in communications at all scheduled communication windows on Wednesday, but it did not send recorded data, only current status information.
  • Status information revealed that the computer had not switched to the usual daily \”sleep\” mode when planned
  • On Thurs, Feb 28, the ground team for NASA\’s Mars rover Curiosity switched the rover to a redundant onboard computer in response to a memory issue on the computer that had been active
  • Flash Memory
  • The condition is related to a glitch in flash memory linked to the other, now-inactive, computer.
  • Diagnostic work in a testing simulation at JPL indicates the situation involved corrupted memory at an A-side memory location used for addressing memory files
  • It appears to have caused the computer to get stuck in an endless loop.
  • Protections and History
  • Curiosity has protections against such high-energy disruptions, but the problem was compounded by what appears to have been the location of the strike-in the directory, or \”table of contents,\” of the computer\’s memory
  • Similar problems were caused by high-energy solar and cosmic ray strikes on other space missions
  • Previous rovers experienced many so-called \”anomalies\” during the early part of their treks
  • Like many spacecraft Curiosity carries a pair of redundant main computers in order to have a backup available if one fails
  • Each of the computers, A-side and B-side, also has other redundant subsystems linked to just that computer
  • Operations
  • Curiosity is now operating on its B-side, as it did during part of the flight from Earth to Mars. It operated on its A-side from before the August 2012 landing through Wednesday.
  • Although scientific investigations by the rover were suspended the team hopes that Curiosity would resume science work in about a week.
  • While resuming operations on the B-side, they are also working to determine the best way to restore the A-side as a viable backup
  • What Happens Next
  • Even if the rover is fully operational again in a week, the amount of science it can perform is limited.
  • The sun comes between Mars and the Earth in early April, partially blocking the path for radio commands for an entire month
  • The Curiosity team had planned to send back science data from Mars during that period-called \”solar conjunction,\” but had decided not to send up any commands.

Show Notes:

Tiny Exo-planet

  • Scientists have discovered a new planet orbiting a Sun-like star, and the exoplanet is the smallest yet found in data from the Kepler mission
  • This discovery came from a collaboration between Kepler scientists and a consortium of international researchers who employ asteroseismology
  • Asteroseismology\”
  • Sound waves travel into the star and bring information back up to the surface, these waves cause oscillations that Kepler observes as a rapid flickering of the star’s brightness
  • Asteroseismology is when scientists measure those oscillations in the star’s brightness caused by continuous star-quakes, and turn those tiny variations in the star’s light into sounds
  • It is similar to how geologists use seismic waves generated by earthquakes to probe the interior structure of Earth
  • Barely discernible, high-frequency oscillations in the brightness of small stars are the most difficult to measure, the bigger the star, the lower the frequency, or ‘pitch’ of its song
  • Kepler-37b
  • The measurements made by the astroseismologists allowed the Kepler research team to more accurately measure the tiny Kepler-37b
  • Kepler-37b, is smaller than Mercury, but slightly larger than Earth’s Moon
  • Orbits every 13 days at less than one-third Mercury’s distance from the Sun
  • Very likely a rocky planet with no atmosphere or water, similar to Mercury
  • Estimated surface temperature of this smoldering planet, at more than 800 degrees Fahrenheit (700 degrees Kelvin, hot enough to melt the zinc in a penny
  • The rest of the Kepler-37 system
  • Kepler-37 has a radius just three-quarters of the Sun, and is about 210 light-years from Earth.
  • The size is known to 3 percent accuracy, which translates to exceptional accuracy in the planet’s size.
  • Measurements also revealed two other planets in the same planetary system: one slightly smaller than Earth and one twice as large
  • All three planets orbit the star at less than the distance Mercury is to the Sun Kepler-37c and Kepler-37d, orbit every 21 days and 40 days, respectively
  • What this means
  • This discovery took a long time to verify, as the signature of this very small exoplanet was hard to confirm
  • Uncovering a planet smaller than any in our solar system orbiting one of the few stars that is both bright and quiet, where signal detection was possible
  • “The detection of such a small planet shows for the first time that stellar systems host planets much smaller as well as much larger than anything we see in our own Solar System.” [Published paper in Nature]

Medical \”Super Glue\” for Wet Surfaces

  • The Problem\”
  • Not even Super Glue will stick in a wet environment because a layer of water forms that keeps the two surfaces from bonding
  • Mussels somehow elbow the water aside and bind themselves to rocks anyway by secreting liquid proteins that harden into a solid, water-resistant glue
  • A Possible New Solution
  • One researcher now says he has used the mollusk’s tricks to develop medical applications
  • This biocompatible glue that could one day seal fetal membranes, allowing prenatal surgeons to repair birth defects without triggering dangerous premature labor
  • The research team has now created a synthetic, thread-like polymer called polyethylene glycol that mimics the mussel protein
  • Basis of a Mussels Sticking Ability
  • Parts of the proteins that face out toward the hard surface
  • This enables liquid holdfast proteins to solidify rapidly and stick flawlessly to wet and salty surfaces
  • Initial Testing
  • To see if the compound worked in live animals, a veterinary surgeon made a 2.5-centimeter incision in the carotid artery of a dog and placed four stitches along the length of that incision to hold it in place
  • With stitches alone were used, the incision bled when the surgeon pressed it.
  • After just 20 seconds after the mussel-based glue was applied, the artery was sealed and didn’t bleed.
  • Recently the team began testing its glue on fetal membranes
  • Possible Prenatal Use
  • For the past few decades, surgeons have begun surgically repairing birth defects like spina bifida while a fetus is still in utero
  • The process is risky because the surgery risks rupturing the fetal membrane prematurely, sending the mother into premature labor.
  • There are no good adhesives on the market for surgeons to repair such fetal-membrane tears
  • In recent, unpublished experiments in rabbits, the team has found that after a veterinary surgeon poked a 3.5-mm hole in the animal’s fetal membrane, the new, mussel-inspired glue readily sealed up the puncture
  • Without the glue, only 40% of the fetal rabbits survived the surgery, but with the glue, 60% did.
  • Fetal surgeons are now working with the research team to test whether the glue can help reseal the tissue surrounding the spinal cord to repair a serious birth defect known spina bifida in rabbits
  • Recent Alterations
  • In another recent result researchers chemically altered the polyethylene glycol polymer so that the glue would shrink when it hardened
  • This could counter tissue swelling during surgery

Food Ninja Dogs

  • A new study suggests dogs might understand people even better than we thought
  • The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room
  • Dogs have specialized skills in reading human communication, specific in dogs
  • The Test
  • A research team recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms
  • The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor
  • They then repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark
  • What the team found was that the dogs were four times as likely to steal the food-and steal it more quickly—when the room was dark
  • It was thought that whether the dogs saw the human would would affect the results, but weather the dogs saw the human or not didn\’t affect the behavior
  • The dog\’s behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food
  • Results and Future
  • The study of dog cognition suddenly began about 15 years ago
  • Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children
  • Dogs are better at reading human cues than even our closest mammalian relatives
  • Researchers are now interested in whether the dog has a theory of mind, \”an understanding that others have different perspective, knowledge, feelings than we do\”
  • While research reveals more and more insight into the minds we still don\’t know just how smart they are

Dennis Tito, Space Tourist, Now Mars Mission Planner

  • ”The Plan\”
  • Dennis Tito, the first-ever space tourist, is planning send a human mission to Mars in January 2018 on a round-trip journey lasting 501 days
  • Reportedly, Tito has created a new nonprofit company called the Inspiration Mars Foundation to facilitate the mission
  • Presentation
  • Tito, along with several other notable people from the space community will provide more information in a press conference set for Wednesday, February 27th
  • The paper Tito plans to present at the IEEE Aerospace Conference in March, will discuss a crewed free-return Mars mission that would fly by Mars, not going into orbit or landing
  • Initial Mission Breakdown
  • The 501-day mission would launch in January 2018, “using a modified SpaceX Dragon spacecraft launched on a Falcon Heavy rocket,”
  • Existing environmental control and life support system (ECLSS) technologies would allow such a spacecraft to support two people for the mission,
  • The paper outlines how NASA would also have a role in this mission in terms of supporting key life support and thermal protection systems, even though this is a private-sector effort
  • Crew comfort would be limited to survival needs only, sponge baths are acceptable, with no need for showers
  • Of Note
  • No estimates of what such a mission would cost are included in the paper, but it does say it would be financed privately
  • The paper adds that if they miss this favorable 2018 opportunity, the next chance to take advantage of this lower energy trajectory would be in 2031.

Another Step for Bionic Eyes

  • Clinical Trials
  • As part of the first module of second human clinical trials in Germany research found that, during the course of a three to nine month observation period, functional vision was restored in the majority of nine patients implanted with a subretinal microchip
  • Patients were implanted with Retina Implant AG\’s subretinal wireless 3×3 mm2, 1500 pixel Alpha IMS microchip and are able to adjust the level of stimulation received to view objects at varied distances
  • Test Data
  • Visual acuity for two of the nine patients surpassed the visual resolution of patients from the Company\’s first human clinical trial
  • Of the nine patients observed in the study, three patients were able to read letters spontaneously during observation in and outside the laboratory patients
  • They also reported the ability to recognize faces, distinguish objects such as telephones and read signs on doors
  • Results
  • Results from the first trial concluded that the implantation of Retina Implant\’s microchip was successful in restoring useful vision in patients previously blind due to retinitis pigmentosa
  • second clinical trial with a wireless device that allows patients to use the implant outdoors and at home and has since expanded into the multicentre phase

Russian Meteorite Orbital Calculations

  • Initial Calculations
  • Just a week after a huge fireball streaked across the skies of the Chelyabinsk region of Russia, astronomers published a paper that reconstructs the orbit and determines the origins of the space rock
  • Scientists at the University of Antioquia in Colombia used a resource not always available in meteorite falls: the numerous dashboard and security cameras that captured the huge fireball
  • Using the trajectories shown in videos posted on YouTube, the researchers were able to calculate the trajectory of the meteorite as it fell to Earth and use it to reconstruct the orbit in space of the meteoroid before its violent encounter with our planet.
  • Although the results are preliminary and they are already working on getting more precise results, through their calculations, the team determined the rock originated from the Apollo class of asteroids
  • In addition to the video data they Google Earth to reconstruct the path of the rock as it entered the atmosphere and showed that it matched an image of the trajectory taken by the geostationary Meteosat-9 weather satellite.
  • Even with the plethora of video\’s due to variations in time and date stamps on several of the videos, some which differed by several minutes, they decided to choose two videos from different locations that seemed to be the most reliable
  • From triangulation, they were able to determine height, speed and position of the meteorite as it fell to Earth

Remembering David McKay [September 25, 1936 – February 20, 2013]

  • As a graduate student, McKay was in the audience when President John F. Kennedy gave his legendary \”We choose to go to the moon\” speech
  • McKay joined NASA in June of 1965 and participated extensively in astronaut training leading up to 1969\’s historic Apollo 11 mission
  • He also served as chief scientist for astrobiology at NASA\’s Johnson Space Center in Houston
  • McKay was lead author of a 1996 paper in the journal Science that suggested ALH84001 may contain evidence of past life on Mars.
  • While the claim still spurs controversy, it also sparked a shift in perspectives that is alive and well within NASA today and prompted the establishment of the NASA Astrobiology Institute
  • McKay developed innovative new technology for both life detection and the use of lunar regolith as feedstock, radiation protection, fuel, nutrient source for microbial bioreactors and long-term lunar habitation.
  • Publications
  • David published more than 200 peer-reviewed papers on lunar samples, space resource utilization, cosmic dust, meteorites, astrobiology and Mars topics, as well as about twice that many published abstracts, and this body of work includes many contributions to our understanding of the development and evolution of the lunar regolith and space weathering processes

Looking back

  • March 05, 1223 BC : 3236 years ago : Oldest Eclipse Record : The oldest recorded eclipse occurred, according to one plausible interpretation of a date inscribed on a clay tablet retrieved from the ancient city of Ugarit, Syria (as it is now). This date is favoured by recent authors on the subject, although alternatively 3 May 1375 BC has also been proposed as plausible. Certainly by the 8th century BC, the Babylonians were keeping a systematic record of solar eclipses, and possibly by this time they may have been able to apply numerological rules to make fairly accurate predictions of the occurrence of solar eclipses. The first total solar eclipse reliably recorded by the Chinese occurred on 4 Jun 180 BC.

Dark Matter Announcement Coming

  • Dark Matter
  • The dark matter theory was born 80 years ago when Swiss astrophysicist Fritz Zwicky discovered that there was not enough mass in observable stars or galaxies to allow the force of gravity to hold them together
  • The Standard Model only accounts for only around four or five percent of the stuff in the Universe that we see
  • It could be useful for identifying the stable of particles and forces that regulate our daily life, the Standard Model only tells part of the cosmic story
  • Dark matter, could make up 23 percent, and dark energy, an enigmatic force that appears to drive the expansion of the Universe, could accounts for around 72 or 73 percent
  • Some physics theories suggest that dark matter is made of WIMPS (weakly interacting massive particles), a class of particles that are their own antimatter partner particles
  • When matter and antimatter partners meet, they annihilate each other, so if two WIMPs collided, they would be destroyed, releasing a pair of daughter particles – an electron and its antimatter counterpart, the positron, in the process
  • Although we can not explain gravity, although we know how to measure gravity and exploit it for our needs
  • Announcement Coming Up
  • In about two weeks the first paper of results of the Alpha Magnetic Spectrometer, a particle collector mounted on the outside of the International Space Station, will be published
  • Researchers have said that the results bear on the mystery of dark matter, that \”It will not be a minor paper\” and that they rewrote the paper 30 times before they were satisfied with it
  • Even with this tease for a \’major announcement\’ scientists still say it represents a \”small step\” in figuring out what dark matter is, and perhaps not the final answer
  • Tracking Cosmic Particles
  • To track these phantom particles, physicists rely on several methods and tools
  • The Large Hadron Collider (LHC) near Geneva, the biggest particle smasher in the world
  • The South Pole Neutrino Observatory, tracks subatomic particles known as neutrinos, which, according to physicists, are created when dark matter passes through the Sun and interacts with protons
  • The Alpha Magnetic Spectrometer (AMS) aboard the International Space Station (ISS), captures gamma rays coming from collisions of dark matter particles.
  • Alpha Magnetic Spectrometer
  • Has the potential to detect the positrons and electrons produced by dark matter annihilations in the Milky Way
  • It was installed on the International Space Station in May 2011, and so far, it has detected 25 billion particle events, including about 8 billion electrons and positrons
  • This will first science paper from this instrument that will report how many of each were found, and what their energies are
  • If the experiment detected an abundance of positrons peaking at a certain energy, that could indicate a detection of dark matter,
  • What it Might Mean for What We Might Find
  • There is a lot of stuff that can mimic dark matter,\”
  • If the experiment detected an abundance of positrons peaking at a certain energy, that could indicate a detection of dark matter,
  • While electrons are abundant in the universe around us, there are fewer known processes that could give rise to positrons
  • The smoking gun signature is a rise and then a dramatic fall\” in the number of positrons with respect to energy
  • The positrons produced by dark matter annihilation would have a very specific energy, depending on the mass of the WIMPs making up dark matter
  • Another telling sign will be the question of whether positrons appear to be coming from one direction in space, or from all around
  • If they\’re from dark matter, scientists expect them to be spread evenly through space, but if they\’re created by some normal astrophysical process, such as a star explosion, then they would originate in a single direction
  • Regardless of whether AMS has found dark matter yet, the scientists said they expected the question of dark matter\’s origin to become clearer soon

Lightning and Headaches

  • The New Study
  • A new study has found a 31 percent increase of the risk of headache and a 28 percent increased risk of migraine for chronic headache sufferers on days that lightning struck within 25 miles (40 kilometers) of their homes
  • In addition new-onset headaches and migraines increased by 24 percent and 23 percent, respectively
  • The Correlation
  • This is the first study to show a correlation between lightning and associated weather phenomena and the squalls in our heads
  • How exactly lightning might trigger headaches is still unknown but there are a number of possible explanations
  • Electromagnetic waves emitted from lightning could trigger headaches
  • Another explanation might be that lightning produces increases in air pollutants like ozone, and can cause release of fungal spores that might lead to migraine
  • Still Unknown
  • This study does show an apparent link between lightning and headaches; however, the exact mechanisms through which lightning and/or its associated meteorologic factors trigger headache is still unknown

CERN, the Higgs-Boson, and Upgrades

  • Upgrades
  • Over the past three years, CERN has slammed protons together more than six million billion times
  • Now seven months after the discovery announcement for a Boson, which they are now 99.9 percent certain is the Higgs-Boson, CERN scientists have brought CERN offline for an 18-month upgrade
  • The upgrade will boost the LHC\’s energy capacity, essential for CERN to confirm definitively that its boson is the Higgs, and allow it to probe new dimensions such as supersymmetry and dark matter
  • The Data
  • Scientists still have vasts amount of data to comb through during this downtime,
  • Even with the shutdown, CERN\’s researchers won\’t be taking a breather, as they must trawl through a vast mound of data
  • They expect that they will have much more information about the data from the last three years, and once they are able to go back through the data they will probably have more questions, some of which will lead to more tests under the new upgrades
  • What’s to Come
  • In 2011 the LHC has able to achieve collisions with an energy level of seven teraelectron volts
  • During 2012 CERN was able to increase to eight teraelectron volts
  • When it comes back online in 2015 after the upgrades are completed they will be able to achieve 13-14
  • It is expected that CERN will then run at those conditions for three to four years before more upgrades are installed

Space Station Communication

  • NASA\’s Mission Control center in Houston lost communication with the International Space Station at 9:45 a.m. ET (1445 GMT). [19 Feb 2013]
  • They restored contact with the space station at 12:34 p.m. ET (17:34 GMT),
  • A NASA official said \”Flight controllers were in the process of updating the station’s command and control software and were transitioning from the primary computer to the backup computer to complete the software load when the loss of communication occurred,\”
  • A main data relay system malfunctioned, and the computer that controls the station\’s critical functions switched to a backup
  • \”Mission Control Houston was able to communicate with the crew as the space station flew over Russian ground stations before 11:00 a.m. EST and instructed the crew to connect a backup computer to begin the process of restoring communications,\”
  • This is not the first time Mission Control has lost direct communication with the orbiting science laboratory
  • In 2010, the space station briefly lost communication with the ground when a primary computer failed and the backup had to take over. Communications were out for about one hour before NASA restored the connection

SCIENCE CALENDAR

Looking back

  • February, 20 1962 : 51 years ago : Glenn in orbit : John Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first U.S. manned orbital mission. [The first manned orbital flight was Yu. Gagarin on the the Vostok 1 on 12 April 1961]
    Launched from Kennedy Space Center, Florida, he completed three-orbits around the earth, at a maximum altitude of approx. 162 miles and an orbital velocity of approx. 17,500 mph. He spotted Perth, Australia, when that city\’s residents greeted him by switching on their house lights in unison. A four-cent U.S. stamp was put on sale the same day, making it the first U.S. stamp issued on the day of the event it commemorated. Glenn returned to space 36 years later, making 134 more orbits as a crew member of the space shuttle Discovery (29 Oct – 7 Nov 1998) for investigations on space flight and the aging process.
