Path of Destruction: Star Wars: Darth Bane, Book 1

• 2,000 years after KOTOR

Brains and Bilingual Language

• According to new research, individuals who learn two languages at an early age seem to switch back and forth between separate \”sound systems\” for each language
• Previous Ideas on the Brain and Languages
• One idea was that people who speak more than one language have different processing modes for their two languages
• One mode for processing speech in one language and then a mode for processing speech in the other language
• Another view was that bilinguals just adjust to speech variation by calibrating to the unique acoustic properties of each language
• New Research Supports…
• Kalim Gonzales, a psychology doctoral student at the University of Arizona, research supports the first view
• When most people think about the difference in languages they think of the different words and grammar, but at the root of the languages are different sounds
• The Study – Setup
• The study looked at 32 Spanish-English early bilinguals, who had learned their second language before age 8
• Participants were presented with a series of pseudo-words beginning with a \’pa\’ or a \’ba\’ sound and asked to identify which of the two sounds they heard
• \’pa\’ and \’ba\’ sounds exist in both English and Spanish, how those sounds are produced and perceived in the two languages varies subtly
• For example, for English speakers \’ba\’ typically begin to vibrate their vocal chords the moment they open their lips
• Spanish speakers begin vocal cord vibration slightly before they open their lips and produce \’pa\’ in a manner similar to English \’ba.\’
• English-only speakers might, in some cases, confuse the \’ba\’ and \’pa\’ sounds they hear in Spanish
• The Study – Bilingual Participants
• The bilingual participants were divided into two groups. One group was told they would be hearing rare words in Spanish, while the other was told they would be hearing rare words in English
• Both groups heard audio recordings of variations of the same two non real words bafri and pafri
• Both groups heard the same series of words, but for the group told they were hearing Spanish, the ends of the words were pronounced slightly differently, with the \’r\’ getting a Spanish pronunciation
• Participants perceived \’ba\’ and \’pa\’ sounds differently depending on whether they were told they were hearing Spanish words, with the Spanish pronunciation of \’r,\’ or whether they were told they were hearing English words, with the English pronunciation of \’r.\’
• When they put people in \”English mode,\” they actually would act like English speakers, and then if you put them in Spanish mode, they would switch to acting like Spanish speakers
• Hearing the exact same \’ba\’s and \’pa\’s would label them differently depending on the context
• The Study – Bilingual Participants
• When the study was repeated with 32 English monolinguals, participants did not show the same shift in perception
• They labeled \’ba\’ and \’pa\’ sounds the same way regardless of which language they were told they were hearing
• What Does That Mean?
• Difference between the two groups provided the strongest evidence for two sound systems in bilinguals
• This is primarily true for those who learn two languages very young
• If you learn a second language later in life, you usually have a dominant language and then you try to use that sounds system for the other language, which is why you end up having an accent
• Bilinguals who learn two languages early in life learn two separate processing modes, or \”sound systems\”
• One of the reasons it sounds different when you hear someone speaking a different language is because the actual sounds they use are different
• Someone might sound like they have an accent if they learn Spanish first is because their \’pa\’ is like an English \’ba,\’ so when they say a word with \’pa,\’ it will sound like a \’ba\’ to an English monolingual

Diet Help Makes Cancer Cells Mortal

• New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells\’ \”superpower\” to escape death
• By altering a very specific step in gene regulation, this compound essentially re-educates cancer cells into normal cells that die as scheduled.
• Apigenin
• One way that cancer cells thrive is by inhibiting a process that would cause them to die on a regular cycle that is subject to strict programming
• Researchers, found that a compound in certain plant-based foods, called apigenin, could stop breast cancer cells from inhibiting their own death.
• Parsley, celery and chamomile tea are the most common sources of apigenin, but it is found in many fruits and vegetables
• Through additional experimentation, the team established that apigenin had relationships with proteins that have three specific functions
• Among the most important was a protein called hnRNPA2, which influences the activity of messenger RNA, or mRNA, which contains the instructions needed to produce a specific protein
• Splicing
• The production of mRNA results from the splicing, or modification, of RNA that occurs as part of gene activation, abnormal splicing is the culprit in an estimated 80 percent of all cancers
• In cancer cells, two types of splicing occur when only one would take place in a normal cell – a trick on the cancer cells\’ part to keep them alive and reproducing.
• Researchers observed that apigenin\’s connection to the hnRNPA2 protein restored this single-splice characteristic to breast cancer cells, eliminating the splicing form that inhibited cell death
• This suggests that when splicing is normal, cells die in a programmed way, or become more sensitive to chemotherapeutic drugs.

Dog Understanding Grammer

• In experiments directed by her owner a 9-year-old border collie has demonstrated a grasp of the basic elements of grammar by responding correctly to commands such as “to ball take Frisbee” and its reverse, “to Frisbee take ball.”
• Word Training
• The dog had previous, extensive training to recognize classes of words including nouns, verbs and prepositions
• Throughout the first three years of the dogs life she was trained to recognize and fetch more than 1,000 objects by name
• Researchers also taught the meaning of different types of words, such as verbs and prepositions and sentence training at age 7
• The dog learned that phrases such as “to Frisbee” meant that she should take whatever was in her mouth to the named object.
• An experimenter would say, for instance, “to ball take Frisbee.” In initial trials, the experimenter pointed at each item while saying its name.
• After several weeks of training, two experiments were conducted
• The Experiments – \’Eyeing the Prize\’
• In one experiment the dog had to choose an object from one pair to carry to an object from the other pair
• Researchers read commands that included words for those objects. Only some of those words had been used during sentence training
• To see whether Chaser grasped that grammar could be used flexibly student also read sentences in the reversed form of “take sugar to decoy.”
• In 28 of 40 attempts, the dog grabbed the correct item in her mouth and dropped it next to the correct target.
• The Experiments – Hidden in Plain Sight
• Another experiment tested the dogs ability to understand commands when she couldn’t see the objects at first
• Researchers placed two objects behind her at the other end of the bed, after hearing a command, the dog turned around and nabbed one of the objects.
• Then ran to the living room and delivered the item to one of another pair of objects. She succeeded on all 12 trials
• What is Exactly Happening
• Exactly how the dog gained her command of grammar is unclear although researchers suspects that she first mentally linked each of two nouns she heard in a sentence to objects in her memory

A Year on Mars, on Earth

• The Mars Society has just announced a year long simulation of astronauts on Mars in the arctic
• The proposed Mars Arctic 365 (MA365) mission on Canada’s Devon Island would take place at Flashline Mars Arctic Research Station
• According to the Mars Society the arctic is a lot like Mars in that it is cold, isolated, and dangerous
• The society is asking for $50,000 from supporters in the next 24 days before starting the first phase (basically retrofitting the station and adding equipment) in July
• More information on MA365 – perhaps with information on crew selection – should come in August, when members of the Phase 1 crew issue a report at the 16th Annual International Mars Society Convention

Kepler Strategies

• What\’s the Latest?
• Kepler engineers are now strategizing about how to remotely repair one of two broken reaction wheels that precisely point the telescope
• It will take at least several weeks before they beam commands up to the $600-million telescope, and they admit that a fix is a long shot.
• Kepler Exoplanet History
• When Kepler was launched into space astronomers knew that the galaxy contained at least 350 exoplanets, nearly all of them the size of Jupiter or larger
• Kepler’s then spent four years adding nearly 3,000 planets
• Now astronomers are convinced that the Milky Way contains hundreds of billions of planets, roughly one for every star, with at least 17 billion of them Earth-sized
• Kepler’s main goal was to determine the frequency of Earthlike planets in the galaxy while they now have enough data to make an intelligent extrapolation about what that number is, determining a more exact number will remain in limbo unless the telescope comes back online
• What\’s the Next Mission
• NASA’s next exoplanet-hunting mission, the Transiting Exoplanet Survey Satellite, TESS, is scheduled for a 2017 launch
• Whereas Kepler has fixed its gaze on distant stars, TESS will focus on bright, nearby stars so that powerful telescopes like the upcoming James Webb Space Telescope will be able to probe the atmospheres of planets that TESS discovers
• While less sensitive than Kepler, will nonetheless uncover plenty of planets in our neighborhood, including a handful of Earth-sized worlds
• Astronomers hope to pair size measurements of planets observed by telescopes such as TESS with mass readings from ground-based scopes that look for subtle wobbles in stars’ motion caused by the gravitational pull of orbiting planets.

Opportunity, Still Hard at Work

• Opportunity, has just discovered the strongest evidence to date for an environment favorable to ancient Martian biology
• Opportunity’s analysis of a new rock target named “Esperance” confirmed that it is composed of a “clay that had been intensely altered by relatively neutral pH water
• Esperance is unlike any rock previously investigated by Opportunity; containing far more aluminum and silica which is indicative of clay minerals and lower levels of calcium and iron.
• Most, but not all of the rocks inspected to date by Opportunity were formed in an environment of highly acidic water
• This represents the most favorable conditions for biology that Opportunity has yet seen in the rock histories it has encountered
• Water that moved through fractures during this rock’s history would have provided more favorable conditions for biology than any other wet environment recorded in rocks Opportunity has seen
• Opportunity accomplished the ground breaking new discovery by exposing the interior of Esperance with her still functioning Rock Abrasion Tool (RAT) and examining a pristine patch using the microscopic camera and X-Ray spectrometer on the end of her 3 foot long robotic arm.
• This discovery comes at the conclusion of a 20 month long science expedition circling around a low ridge called “Cape York,” the team even committed several weeks to getting this one measurement of it
• Esperance stems from a time when the Red Planet was far warmer and wetter billions of years ago.
• What’s so special about Esperance is that there was enough water not only for reactions that produced clay minerals, but also enough to flush out ions set loose by those reactions
• Opportunity can clearly see the alterations caused by that process

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.

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

SCIENCE CALENDAR

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.
