Show Notes:

Marijuana’s and Changes to the Brain

  • Young adults who used marijuana only recreationally showed significant abnormalities in two key brain regions that are important in emotion and motivation
  • The Study
  • This is the first study to show casual use of marijuana is related to major brain changes
  • Through different methods of neuroimaging, scientists examined the brains of young adults ages 18 to 25, from Boston-area colleges; 20 who smoked marijuana and 20 who didn\’t. Each group had nine males and 11 females
  • The users underwent a psychiatric interview to confirm they were not dependent on marijuana
  • The changes in brain structures indicate the marijuana users\’ brains are adapting to low-level exposure to marijuana
  • Results
  • The degree of brain abnormalities in these regions is directly related to the number of joints a person smoked per week, the more joints a person smoked, the more abnormal the shape, volume and density of the brain regions
  • Some of these people only used marijuana to get high once or twice a week thinking a little recreational use shouldn\’t cause a problem; however, data directly says this is not the case
  • Scientists examined the nucleus accumbens and the amygdala-key regions for emotion and motivation, and associated with addiction-in the brains of casual marijuana users and non-users
  • Researchers analyzed three measures: volume, shape and density of grey matter to obtain a comprehensive view of how each region was affected.
  • Both these regions in recreational pot users were abnormally altered for at least two of these structural measures and the degree of those alterations was directly related to how much marijuana the subjects used
  • What is Means
  • The study results fit with animal studies that show when rats are given tetrahydrocannabinol (THC) their brains rewire and form many new connections. THC is the mind-altering ingredient found in marijuana
  • Think when people are in the process of becoming addicted, their brains from these new connections
  • In animals, these new connections indicate the brain is adapting to the unnatural level of reward and stimulation from marijuana. These connections make other natural rewards less satisfying
  • The brain changes suggest that structural changes to the brain are an important early result of casual drug use
  • Researchers did not know the THC content of the marijuana, which can range from 5 to 9 percent or even higher, the THC content is much higher today than the marijuana during the 1960s and 1970s, which was often about 1 to 3 percent

Another Earth-sized Exo-Planet

  • The first Earth-sized exoplanet orbiting within the habitable zone of another star has been confirmed by observations with both the W. M. Keck Observatory and the Gemini Observatory
  • The initial discovery, made by NASA\’s Kepler Space Telescope, is one of a handful of smaller planets found by Kepler and verified using large ground-based telescopes
  • The System
  • The host star, Kepler-186, is an M1-type dwarf star relatively close to our solar system, at about 500 light years and is in the constellation of Cygnus
  • The star is very dim, being over half a million times fainter than the faintest stars we can see with the naked eye and is cooler than the Sun
  • Five small planets have been found orbiting this star, four of which are in very short-period orbits and are very hot
  • This Earth-sized planet, one of five orbiting this star, which is cooler than the Sun, resides in a temperate region where water could exist in liquid form
  • Observations
  • Neither Kepler (nor any telescope) is currently able to directly spot an exoplanet of this size and proximity to its host star all they can do is eliminate essentially all other possibilities so that the validity of these planets is really the only viable option
  • With such a small host star, the team employed a technique that eliminated the possibility that either a background star or a stellar companion could be mimicking what Kepler detected
  • Differential Speckle Survey Instrument (DSSI)
  • The team obtained extremely high spatial resolution observations from the eight-meter Gemini North telescope on Mauna Kea in Hawaii using a technique called speckle imaging, as well as adaptive optics (AO) observations from the ten-meter Keck II telescope
  • The Gemini \”speckle\” data directly imaged the system to within about 400 million miles (about 4 AU, approximately equal to the orbit of Jupiter in our solar system) of the host star and confirmed that there were no other stellar size objects orbiting within this radius from the star
  • It works on a principle that utilizes multiple short exposures of an object to capture and remove the noise introduced by atmospheric turbulence producing images with extreme detail

The Brains Distraction Control

  • A new study to reveals that our brains rely on an active suppression mechanism to avoid being distracted by salient irrelevant information when we want to focus on a particular item or task
  • This discovery opens up the possibility that environmental and/or genetic factors may hinder or suppress a specific brain activity that the researchers have identified as helping us prevent distraction.
  • These results show clearly that this is only one part of the equation and that active suppression of the irrelevant objects is another important part
  • Psychologists say their discovery could help scientists and health care professionals better treat individuals with distraction-related attentional deficits
  • Distraction is a leading cause of injury and death in driving and other high-stakes environments
  • Disorders associated with attention deficits, such as ADHD and schizophrenia, may turn out to be due to difficulties in suppressing irrelevant objects rather than difficulty selecting relevant ones
  • Researchers are now turning their attention to understanding how we deal with distraction and why we can\’t suppress potentially distracting objects, whether some of us are better at doing so and why that is the case.

A New Moon for Saturn?

  • A bright clump spotted orbiting Saturn at the outermost edge of its A ring may be a brand new moon in the process of being born
  • The effects of this now 1,200-kilometer-long, 10-kilometer-wide arc of icy material were first seen in May 2012 traveling along the edge of the A ring
  • The arc is thought to be the result of gravitational perturbations caused by an as-yet unseen embedded object about a kilometer wide – possibly a miniature moon in the process of formation
  • The half-mile-wide object has been unofficially named “Peggy,” eventually it may coalesce into a slightly larger moon and move outward, establishing its own orbital path around Saturn
  • This is how many of Saturn’s other moons are thought to have formed much further back in the planet’s history
  • While it is possible that the bright perturbation is the result of an object’s breakup rather than formation, researchers are still looking forward to finding out more about its evolution.

New Horizons and Questions About Pluto

  • Compositional Model Theories
  • Two space researchers have published a paper where they describe three possible interior models of the former planet Pluto
  • The possibilities include: an undifferentiated rock/ice mixture, a differentiated rock/ice mixture, and an ocean covered with ice, the third possibility suggests the likelihood, they claim, of tectonic action on the dwarf planet
  • Scientists believe that Pluto came to exist as it does today, in part due to a collision billions of years ago that led also to the formation of its moon Charon
  • When celestial bodies collide, not only do they knock each other around, they produce heat—heat, the researchers suggest that could still be evident today
  • A theory that suggests that shortly after impact, Pluto and Charon were much closer together where the gravity attraction between them would have caused both to be egg shaped.
  • As time passed, melted ice from the impact would have created an icy crust on top of an ocean on Pluto
  • As Charon moved farther away, the attractive pull would have diminished, causing ice plates to form and crack against one another, a form of tectonics.
  • If that were the case, the two add, then in all likelihood, when New Horizons begins sending back images, they should see evidence of such tectonic action—plate edges thrust into the air
  • Pluto circles the sun in an elliptical orbit, thus sometimes it\’s much closer to the sun than other times, when near, it has a defined atmosphere, when far away however, its atmosphere actually freezes to its surface
  • Something that could hide ridges in the ice and thus evidence of both tectonic activity and an ocean beneath the crust of ice
  • New Horizons will arrive during a time when its atmosphere is frozen to the surface, it might be difficult to determine which of the three proposed models actually describes the relationship between its exterior and interior

— CURIOSITY UPDATE —

  • New Science Location
  • Scientists using NASA\’s Curiosity Mars rover are eyeing a rock layer surrounding the base of a small butte, called \”Mount Remarkable,\” as a target for investigating with tools on the rover\’s robotic arm
  • The butte stands about 16 feet (5 meters) high. Curiosity\’s science team refers to the rock layer surrounding the base of Mount Remarkable as the \”middle unit\” because its location is intermediate between rocks that form buttes in the area and lower-lying rocks that show a pattern of striations
  • Depending on what the mission scientists learn from a close-up look at the rock and identification of chemical elements in it, a site on this middle unit may become the third rock that Curiosity samples with its drill

Looking back

  • April 25, 1990 : 24 years ago : Hubble Space Telescope : 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.

  • Solar Eclipse
  • On April 29th, an annular solar eclipse occurs over a small D-shaped 500 kilometre wide region of Antarctica
  • 2014 has the minimum number of eclipses possible in one year, with four: two partial solars and two total lunars
  • This month’s solar eclipse is also a rarity in that it’s a non-central eclipse with one limit, where the center of the Moon’s shadow – known as the antumbra during an annular eclipse – will juuuust miss the Earth and instead pass scant kilometres above the Antarctic continent
  • Out of 3,956 annular eclipses occurring from 2000 BCE to 3000 AD, only 68 (1.7%) are of the non-central variety
  • An annular eclipse occurs when the Moon is too distant to cover the disk of the Sun, resulting in a bright “annulus” or “ring-of-fire” eclipse
  • Several southern Indian Ocean islands and all of Australia will still witness a fine partial solar eclipse from this event, a scattering of islands in the southern Indian Ocean will see a 55% eclipsed Sun.
  • In Australia, Perth will see a 55% eclipsed Sun and Sydney will be able to see a 50% partial eclipse low to the horizon in west at sunset

A Blood Pressure Drug That Might Help Migraines

  • Researchers have found that the drug Candesartan, used to help lower blood pressure, is as effective in combating migraines as the commonly prescribed drug
  • The Study
  • This finding is a follow up of a ten-year study from NTNU
  • The results were confirmed based on triple a blind test where the doctors, patients and even the researchers were unaware whether the patient was given a placebo or the real drug.
  • The study had 72 participants, who suffered migraine attacks at least twice every month
  • The patients were given placebo, 16 mg of candesartan or 160 mg of propranolol for 12 weeks each and were given a break of 4 weeks without the medicines before the start of the drug and in between too.
  • Study Results
  • More than 20 percent of those suffering with migraine attacks felt better even when they were given a placebo.
  • The blind test revealed that the candesartan works preventively for more 20-30 percent migraine patients
  • The study confirmed that 16 mg of candesartan was as effective as 160 mg of propranolol in treating migraine attacks
  • Researchers say that the drug Candesartan may be prescribed for those who get no relief from propranolol, the most commonly used medication to help prevent migraines

In Memory Of – John Dobson [Sep 14, 1915 – Jan 15, 2014]

  • John Dobson is most notable for being the promoter of a design for a large, portable, low-cost Newtonian reflector telescope that bears his name, the Dobsonian telescope
  • Dobsonian Telescopes
  • Dobsonian Telescope | Wikipedia
  • The design is considered revolutionary since it allowed amateur astronomers to build fairly large telescopes
  • The design is a very simple, low cost [alt-azimuth mounted Newtonian] telescope that employs common materials such as plywood, formica, PVC closet flanges, cardboard construction tubes, recycled porthole glass, and indoor-outdoor carpet
  • He was reluctant to take credit, however, pointing out that he built it that way because it was all he needed
  • Sidewalk Astronomers
  • Sidewalk Astronomers
  • John Dobson was also the co-founder of the amateur astronomical group, the San Francisco Sidewalk Astronomers
  • Has members throughout the world, and continues to promote public service astronomy by putting telescopes on street corners in urban areas
  • Members of the organization also visit national parks giving slide show presentations, providing telescope viewing
  • Misc
  • Earned a masters degree in chemistry at the University of California, Berkeley in 1943, working in E. O. Lawrence\’s lab
  • Dobson’s interest in telescope building was in part to better understand the universe, and in part to inspire in others a curiosity about the cosmos
  • In 2005, the Smithsonian magazine listed John Dobson as among 35 individuals who have made a major difference during the lifetime of that periodical

Mystery Rock for Opportunity

  • An intriguing recent mystery is a strange rock that suddenly appeared in photos from the Opportunity rover in a spot where photos taken just 12 sols earlier showed no rock
  • The team is currently busy taking measurements on the rock, and discussing its origins
  • Mars Exploration Rovers, mission principal investigator Steve Squyres
  • Described the rock as “white around the outside, in the middle there’s low spot that is dark red that \”looks like a jelly donut\”
  • “We had driven a meter or two away from here and somehow maybe one of the wheels managed spit it out of the ground. That’s the more likely theory.”
  • “One theory is that we somehow flicked it with a wheel\” … \”the other theory is that there might be a smoking hole in the ground nearby and this may be crater ejecta. But that one is less likely,”
  • Another idea suggested by others is that it may have tumbled down from a nearby rock outcrop
  • \”We’ve taken pictures of both the donut part and the jelly part,”
  • “The jelly part is like nothing we’ve seen before on Mars. It’s very high in sulfur and magnesium and it has twice as much manganese as anything we’ve seen before\”
  • \”I don’t know what any of this means. We’re completely confused, everybody on the team is arguing and fighting. We’re having a wonderful time!”

New Horizons Journey to Pluto

  • Last Time on SciByte
  • SciByte 30 | Solar Storms & Private Space Flight | Jan 24, 2012
  • Closest approach
  • Closest approach is scheduled for July 2015 when New Horizons flies only 10,000 km [6,200 mi] from Pluto
  • If New Horizons flew over Earth at the same altitude, it could see individual buildings and their shapes
  • Other than a few indistinct markings seen from afar by Hubble, Pluto\’s landscape is totally unexplored
  • Approaching Pluto
  • The first step, in January 2015, is an intensive campaign of photography by the Long Range Reconnaissance Imager or \”LORRI.\”
  • This will help mission controllers pinpoint Pluto\’s location, which is uncertain by a few thousand kilometers, 1000-3000 km [ 621 – 1864 mi ]
  • The scientists will then use the images to refine Pluto\’s distance from the spacecraft, and then fire the engines to make any necessary corrections
  • By late April 2015, the approaching spacecraft will be taking pictures of Pluto that surpass the best images from Hubble

  • January 26, 1700 : 314 years ago : Canadian Earthquake : In 1700, an earthquake, the most intense Canada has ever seen, hit the sea floor off the British Columbia coast. Long before Europeans first landed on Vancouver Island, native legend tells of a great disaster. The sea rose in a heaving wave, and landslides buried a sleeping village. Myth was resolved with science in 2003 by government research. Earthquakes of that intensity cause tidal waves, and Japanese written history tells of a massive tsunami striking fishing villages the next day along the coast of Honshu, killing hundreds. Coupled with geological evidence of the level 9 quake, the connection was clear. Mythology and seismology came together to validate history. 1700 Cascadia earthquake | Wikipedia

Sleep and Fear

  • A fear memory was reduced in people by exposing them to the memory over and over again while they slept
  • The Study
  • Scientists have shown that sleep is very important for strengthening new memories
  • Previous projects have shown that spatial learning and motor sequence learning can be enhanced during sleep
  • If the results of this new study continue to show promising results it will be the first time that emotional memory have been manipulated in humans during sleep
  • What it Could Mean
  • It offers the potential of a new way to enhance typical daytime treatments of phobias, through exposure therapy by adding a nighttime component
  • If it can be extended to pre-existing fear, the bigger picture is that, perhaps, the treatment of phobias can be enhanced during sleep.\”
  • The Test
  • 15 healthy human subjects received mild electric shocks while seeing two different faces
  • Subjects also received different odorants to smell with each face such as woody, clove, new sneaker, lemon or mint
  • This caused the brain to associate the faces and corresponding smells with fear
  • During the slow wave sleep state, when memory consolidation is thought to occur, a smell was represented without the corresponding face and shock
  • When a given smell was reintroduced during sleep, it was activating the memory of that face over and over again
  • The Results
  • When the subjects woke up they saw the face linked to the smell they had been exposed to during sleep
  • Their fear reactions were lower than their fear reactions to the other face
  • Fear was measured in two ways, through small amounts of sweat in the skin, similar to a lie detector test and through neuroimaging with fMRI (functional magnetic resonance imaging).
  • The fMRI results showed changes in regions associated with memory and changes in patterns of brain activity in regions associated with emotion
  • These brain changes reflected a decrease in reactivity that was specific to the targeted face image associated with the odorant presented during sleep

Lunar Formation and Age

  • New research suggests that the moon is younger than scientists had previously believed
  • Current Leading Lunar Formation Theory
  • Suggest that the Moon was created when a mysterious planet, one the size of Mars or larger, slammed into the Earth about 4.56 billion years ago, just after the solar system came together
  • New analyses of lunar rocks suggest that the moon, is actually between 4.4 billion and 4.45 billion years old
    +This analysis would mean the moon would 100 million years younger than previously thought and would reshape scientists\’ understanding of the early Earth
  • Opens New Questions
  • Giving the Earth another 100 million years of development before a giant impact could have provided enough time for a primordial atmosphere to develop
  • If that did have time to occur, could an impact have been able to \’blown off\’ that atmosphere
  • Age of Smaller Solar System Bodies
  • Scientists are very sure that the solar system\’s age is 4.568 billion years
  • They can pin down the formation times of relatively small bodies such as asteroids precisely
  • By noting when these objects underwent extensive melting, from the heat generated by the collision and fusion of these objects\’ building-block \”planetesimals.\”
  • Analysis of meteorites that came from the asteroid Vesta and eventually rained down on Earth reveals that the 330-mile-wide (530 kilometers) space rock is 4.565 billion years old
  • Vesta cooled relatively quickly and is too small to have retained enough internal heat to drive further melting or volcanism
  • Age of Larger Solar System Bodies
  • The age of larger solar-system bodies is harder to narrow down
  • Earth likely took longer to grow to full size compared to a small asteroid like Vesta
  • Every step in its growth tends to erase, or at least cloud, earlier events
  • Lunar formation Impact Event
  • Currently the \’lunar formation impact event\’ puts the age of the Moon at around 4.56 billion years ago
  • As scientists refine techniques and technology improves, estimates are pushing the moon\’s formation date farther forward in time
  • The moon is thought to have harbored a global ocean of molten rock shortly after its formation
  • Currently, the most precisely determined age for the lunar rocks that arose from that ocean is 4.360 billion years
  • Here on Earth, scientists have found signs in several locations of a major melting event that occurred around 4.45 billion years ago
  • Evidence is building that the catastrophic collision that formed the moon and reshaped Earth occurred around that time, rather than 100 million years or so before

Infant Blood Sugar

  • Newborns with low blood sugar sometimes have to go to the intensive care unit for intravenous infusions of glucose
  • A new study has found that rubbing a sweet gel onto the insides of babies’ cheeks can also help with low blood sugar
  • Neonatal Hypoglycemia
  • Low blood sugar in newborns, or neonatal hypoglycemia, occurs when the tiny body needs more glucose to meet energy needs than is available in the bloodstream
  • Prolonged hypoglycemia risks neurological injury.
  • Prevalence
  • Low blood glucose shows up in 5 to 15 percent of otherwise healthy newborns as measured by blood tests
  • Of note, doctors typically don’t run the analysis on every newborn
  • Doctors often only call for blood sugar blood tests if they see symptoms, such as poor color, seizures, irritability, lethargy, jittery behavior and a lack of interest in feeding
  • Although many infants with low blood glucose don’t have such symptoms
  • One report designates at-risk infants as those who are born preterm, have diabetic mothers, or are either large or small for their gestational age
  • The Study
  • In the new study, researchers identified 237 apparently healthy newborns who had one of those risk factors or who were feeding poorly
  • Half of the babies were randomly assigned to get a gel made of dextrose, a form of glucose, rubbed on the inner cheeks up to six times over 48 hours; the rest received a placebo gel
  • Results in the Following Week
  • Placebo gel group | 30 babies, 25%, were placed in intensive care for hypoglycemia
  • Dextrose gel group | 16 babies, 13%, were placed in intensive care for hypoglycemia
  • Previous Usage

New Horizons Message Initiative

  • SETI (Search for Extraterrestrial Intelligence) have created a petition called the New Horizons Message Initiative
  • This petition is asking NASA officials to upload a yet-to-be-determined crowdsourced message from humanity onto the New Horizons craft after its encounter with the Pluto system
  • \”This website is an opportunity for anyone who is interested to sign a petition that asks NASA to approve the future use of the spacecraft\”
  • Were There Plans About This from NASA?
  • Before New Horizons launched, NASA officials discussed including an onboard message, but decided against it due to a small team on a tight budget
  • The team didn\’t want to get distracted from the project
  • New Horizons Message Initiative
  • The group would need formal permission from the agency and sub-support to make this happen
  • NASA funds will not be used for the project, but initiative officials are asking for support from private individuals.
  • The idea is to use some of the spacecraft\’s memory to store messages from earthlings beamed up to the probe, when New Horizons completes its mission
  • They say that it might be possible to reprogram about 100 megabytes of its memory and upload a new sights and sounds of Earth

Lightsaber Tech?!?!?!

  • Viewer Feedback : Check This Out
  • Nikki, Summer SciByte co-host, current STOked radio co-host
  • What’s Going On?
  • Researchers have found a way to bind photons together much like molecules
  • This discovery goes against what scientists previously understood of photons: that elementary light particles are massless loners that do not interact with each other.
  • Most of the properties of light we know about originate from the fact that photons are massless, and that they do not interact with each other
  • The Test
  • Researchers fired a couple of photons into a cloud of rubidium – a chemical element belonging to the metal group – in a vacuum chamber cooled to just a few degrees above absolute zero.
  • When the photons exited the other side of the cloud of atoms the researchers were surprised to see the pair emerge as a single molecule.
  • The cloud they passed through is a special type of medium in which photons interact with each other strongly that they begin to act as though they have mass, and they bind together to form molecules
  • Rydberg Blockade
  • Rydberg blockade states that when an atom has energy imparted to it, nearby atoms cannot be excited to the same degree
  • The pair of photons moved through the cloud of atoms, the first photon excited atoms, but had to move forward before the second photon could do the same.
  • The pair of photons pushed and pulled each other through the cloud like atomic interaction, which made these two photons behave like a molecule
  • The Future
  • The team is hoping to use their newly discovered state of matter in the advancement of quantum computing

  • Oct 04, 1958 : 55 years ago : Sputnik : The Space Age began as the Soviet Union, to the dismay of the United States, launched Sputnik, the first manmade satellite, into orbit around the earth. The craft circled the earth every 95 minutes at almost 20,000 miles per hour 500 miles above the Earth. The Sputnik (meaning \”companion\” or \”fellow traveller\”) was launched from Kazakhstan. It stayed in orbit for about three months. Sputnik fell from the sky on 4 Jan 1958. The 184-lb satellite had transmitted a radio signal picked up around the world, and instrumentation for temperature measurement

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.

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

Extra-solar Planets

Flinging Chimps

  • The low down
  • Chimps are the only other species besides humans that regularly throw things with a clear target in mind
  • Researchers studying such behavior have come to the conclusion that throwing feces, or any object really, is actually a sign of high ordered behavior
  • Watching chimps in action for several years and comparing their actions with scans of their brains to see if there were any correlations between those chimps that threw a lot and those that didn’t or whether they’re accuracy held any deeper meaning.
  • Chimps that both threw more and were more likely to hit their targets showed heightened development in the motor cortex
  • Better throwing chimps didn’t appear to posses any more physical prowess than other chimps
  • Significance
  • Language processing occurs in the left side, which also controls our right hands; and most people use their right hands to throw, as do chimpanzees.
  • Such findings led the term to suggest that the ability to throw is, a precursor to speech development.
  • Those chimps that could throw better appeared to be better communicators within their group
  • Why did these chimps learn to throw in a captive context? The chimp learns is as a form of communication.
  • Throwing stuff at someone else became a form of self expression
  • * Of Note*
  • While throwing at first might not seem demanding, coordinating it requires intensive, on-the-fly calculations.
  • An equation for throwing a ball, for example, would include the distance to a target, the ball’s heaviness and the thrower’s strength. A moving target makes it even harder

Supernova warning signs?

Alzheimer’s Research

  • The low down
  • One of the earliest known impairments caused by Alzheimer’s disease is the loss of sense of smell
  • There is currently no effective treatment or cure for the disease
  • Since the 1970s, loss of sense of smell has been identified as an early sign of this disease
  • Smell loss can be caused by a number of ailments, exposures or injuries
  • Significance
  • Researchers at Case Western Reserve University School of Medicine have confirmed that the protein, called amyloid beta, causes the loss of sense of smell
  • Amyloid beta plaque accumulated first in parts of the brain associated with smell, well before accumulating in areas associated with cognition and coordination
  • Just a tiny amount of amyloid beta – too little to be seen on today’s brain scans – start this process
  • While losses in the olfactory system occurred, the rest of the mouse model brain, including the hippocampus, which is a center for memory, continued to act normally early in the disease stage
  • Mice were given a synthetic liver x-receptor agonist, a drug that clears amyloid beta from the brain
  • The sense of smell an be restored by removing a plaque-forming protein in a mouse model of the disease
  • After two weeks on the drug, the mice could process smells normally
  • After withdrawal of the drug for one week, impairments returned
  • Team are now following-up on these discoveries to determine how amyloid spreads throughout the brain, to learn methods to slow disease progression
  • * Of Note*
  • We could use the sense of smell to determine if someone may get Alzheimer’s disease
  • Use changes in sense of smell to begin treatments, instead of waiting until someone has issues learning and remembering
  • We can also use smell to see if therapies are working

Voyager 1 – Update

  • The low down
  • Launched : Sep 05, 1977
  • Speed : 10.5 mi/s [17 km/s]
  • Significance
  • NASA’s Voyager Hits New Region at Solar System Edge
  • It has entered a new region between our solar system and interstellar space
  • Voyager 1 is about 11 billion miles (18 billion kilometers) from the sun, it is not yet in interstellar space.
  • The data do not reveal exactly when Voyager 1 will make it past the edge of the solar atmosphere into interstellar space, but suggest it will be in a few months to a few years.

SCIENCE CALENDER

Looking back

  • Dec 11, 1911 – 100 years ago – Marie Curie’s second Nobel Prize : Marie Curie became the first person to be awarded a second Nobel prize. She had isolated radium by electrolyzing molten radium chloride. This second prize was for her individual achievements in Chemistry, whereas her first prize (1903) was a collaborative effort with her husband, Pierre, and Henri Becquerel in Physics for her contributions in the discovery of radium and polonium.
  • *Dec 7–11 1972 – 39 years ago – Last moon mission *: On Dec 7th Apollo 17, the sixth and last U.S. moon mission, blasted off from Cape Canaveral. On Dec 11th astronauts Gene Cernan and Harrison Schmitt landed on the moon for a three-day exploration, while Ronald E. Evans remained in orbit. Flight Commander Eugene Cernan was the last man on the moon. Typically the backup crew for an Appolo mission was to serve as the main crew 3 missions later, but with Appolo 17 scheduled as the last Moon mission there was heavy pressure to put a geologist to the crew (Schmitt.)
  • Dec 10, 1984 – 27 years ago – First Extrasolar Planet Discovery Announcement: The National Science Foundation reported the discovery of the first planet outside our solar system, orbiting a star 21 million light years from Earth. The object was found orbiting Van Biesbroeck 8, an extremely faint star about 21 light years from Earth. However, it seemed to abruptly vanish when later attempts to observe its gravitational pull on Van Biesbroeck 8 failed. It is currently unknown whether the object ever existed.

Looking up this week

  • Keep an eye out for …

  • Wednesday, Dec 7 : As darkness falls, Jupiter is to the upper right of the Moon.

  • –Saturday Dec 10 – Total Eclipse of the Moon–

  • The Moon is totally within the umbra of Earth’s shadow for 52 minutes. The partial stages before and after totality each last more than an hour.

  • At the instant of greatest eclipse (14:32 UT) the Moon lies at the zenith in the Pacific Ocean near Guam.

  • The exact hue (anything from bright orange to blood red is possible) depends on the unpredictable state of the atmosphere at the time of the eclipse. As Jack Horkheimer (1938–2010) of the Miami Space Transit Planetarium loved to say, “Only the shadow knows.”

  • Timeline

  • Partial Eclipse Begins – 4:45am PST / 12:45 GMT

  • Total Eclipse Begins – 6:45am PST / 14:06 GMT

  • Total Eclipse Maximum – 6:32am PST / 14:32 GMT

  • Total Eclipse Ends – 6:14am PST / 14:57 GMT

  • Partial Eclipse Ends – 8:17am PST / 16:17 GMT

  • What you can see

  • NASA

  • ShadowAndSubstance

  • United States & Canada : The western United States and Canada will witness a total lunar eclipse. The action begins around 4:45am PST when the red shadow of Earth first falls across the lunar disk. By 6:05am PST, the Moon will be fully engulfed in red light.

  • Europe : Seen as rising over eastern Europe

  • Asia and Australia : Visible from all of Asia and Australia
