How Common Are \’Earth-Like\’ Planets?

  • Astronomers have analyzed all four years of Kepler data in search of Earth-size planets in the habitable zones of sun-like stars
  • Based on the analysis, they estimate that 22 percent of stars like the sun have potentially habitable Earth-size planets, though not all may be rocky or have liquid water
  • Kepler Space Telescope
  • Launched in 2009 its mission was to look for planets around other stars by looking for a \’dip\’ in the brightness of a star, about one hundredth of one percent, indicating that something was passing in front of it
  • After 3 consecutive dips in light from the star it is labeled a exoplanet candidate
  • About 150,000 stars were photographed every 30 minutes for four years leading to the current reported number of more than 3,000 planet candidates
  • Kepler had to be pointed with such precision in order to find these planets that it would be like steadily looking at a grain of salt from a 0.4 km [1/4 mi] away
  • The Keck Telescopes in Hawaii helps astronomers to determine each star\’s true brightness and calculate the diameter of each transiting planet, with an emphasis on Earth-diameter planets.
  • \”Habitability\”
  • The team\’s defined habitable as a planet that receives between four times and one-quarter the amount of light that Earth receives from the sun
  • Earth-size planets in Earth-size orbits are not necessarily hospitable to life, even if they orbit in the habitable zone of a star where the temperature is not too hot and not too cold
  • Some of those planets may have thick atmospheres, making it so hot at the surface that DNA-like molecules would not survive
  • A habitable planet would have a rocky surfaces that could harbor liquid water suitable for living organisms
  • Narrowing Down The Data
  • The team focused on the 42,000 stars that are \’sun-like\’ and found 603 candidate planets orbiting them
  • Of those only 10 were Earth-size, that is, one to two times the diameter of Earth and orbiting their star at a distance where they are heated to lukewarm temperatures suitable for life
  • Extrapolating
  • All of the potentially habitable planets found in their survey are around K stars, which are cooler and slightly smaller than the sun although analysis shows that the result for K stars can be extrapolated to G stars like the sun
  • In order to get a better idea of the number of stars with planets around them you have to account for missed planets, as well as the fact that only a small fraction of planets are oriented so that they cross in front of their host star as seen from Earth
  • Adding in those numbers led them to believe that roughly 22 percent of all sun-like stars in the galaxy have Earth-size planets in their habitable zones.
  • The astronomers in this study defined sun-like stars to be of two class types, Class G (like our sun) and Class K
  • Class G and K stars make up roughly 19.5% of all stars, 22% of those stars gives 4.3% of ALL stars have potentially habitable Earth-size planets. (1 out of 25)

Musical Training and the Brain

  • Older adults who took music lessons as children but haven\’t actively played an instrument in decades have a faster brain response to a speech sound than individuals who never played an instrument
  • The Brains Response Time
  • As people grow older, they often experience changes in the brain that compromise hearing and show a slower response to fast-changing sounds, which is important for interpreting speech
  • Previous studies have show such age-related declines are not inevitable, in fact recent studies of musicians suggest lifelong musical training may offset these and other cognitive declines
  • The Study
  • This recent study, explored whether limited musical training early in life is associated with changes in the way the brain responds to sound decades later
  • For the study, 44 healthy adults, ages 55-76, listened to a synthesized speech syllable (\”da\”) while researchers measured electrical activity in the auditory brainstem
  • The brainstem is the region of the brain processes sound and is a hub for cognitive, sensory, and reward information
  • Results
  • The results showed that the more years study participants spent playing instruments as youth, the faster their brains responded to a speech sound.
  • In fact none of the study participants had played an instrument in nearly 40 years, so it wasn\’t simply a recent or \’maintenance\’ result
  • Participants who completed 4-14 years of music training early in life had the fastest response to the speech sound (on the order of a millisecond faster than those without music training).
  • A millisecond faster may not seem like much, but the brain is very sensitive to timing and a millisecond compounded over millions of neurons can make a real difference

Olympic Torch in Space

  • The Olympic Torch was taken on a space walk for the first time on Nov 9, 2013
  • Russian officials made it clear that the torch would remain unlit at all times for safety reasons.
  • The Olympic torch was carried into space ahead of the 1996 and 2000 Olympics in Atlanta and Sydney but has never before been taken on a spacewalk
  • In an usual situation, when the new crew arrived there were nine crew members and three Soyuz vehicles at the ISS, there have not been nine crew members on the ISS since 2009.
  • The new crew brought the unlit torch along, then the space station’s current crew, took the torch out on a spacewalk, the three returning crew members brought the torch back to Earth
  • The real reason for the spacewalk is to do some routine Russian maintenance outside the station
  • The torch was given back to Olympic officials and it will be used in the opening ceremonies of the February games

New Shark Species

  • Michael Thalleen ‏@ThalleenM
  • Two new shark species have been discovered
  • Carolina Hammerhead
  • Rare New Species of Carolina Hammerhead Shark Discovered | ScienceWorldReport.com
  • Scientists have now announced that they\’ve discovered a new species of rare shark, the Carolina hammerhead
  • The Carolina hammerhead has long eluded discovery due to the fact that it is outwardly indistinguishable from the common scalloped hammerhead
  • The new species, named Sphyrna gilberti, was actually discovered as scientists were looking for more common hammerheads.
  • South Carolina is a well-known pupping ground for several species of sharks, which means that researchers were collecting samples there for study
  • The scalloped hammerheads that they were collecting had two different genetic signatures in both the mitochondrial and nuclear genomes
  • The scientists found that the anomalous scalloped hammerhead had been described in 1967 and had 10 fewer vertebrae than the normal scalloped hammerhead. Intrigued
  • In the end, the scientists found that there was genetic evidence to show that this hammerhead was, in fact, a new species.
  • At this point scientists aren\’t sure exactly how many individuals still exist in the wild
  • \’Walking\’ Shark
  • New \’Walking\’ Shark Species Caught on Video | LiveScience
  • YouTube | New species of \”walking\” shark found in Indonesia – Conservation International (CI) – 2013 | ConservationDotOrg
  • A new species of \”walking\” shark has been discovered in a reef off a remote Indonesian island
  • Hemiscyllium halmahera, named after the eastern Indonesian island of Halmahera where it was found
  • These sharks don\’t always rely on \”walking\” to move about — often, they only appear to touch the seafloor as they swim using their pectoral and pelvic fins in a walk like gait
  • The shark grows up to 70 cm [27 in] long and is harmless to humans
  • The animals lay eggs under coral ledges, after which the young sharks lead relatively sedentary lives until adulthood
  • These sharks do not cross areas of deep water and are found in isolated reefs

— SPACECRAFT UPDATE—

India’s Mars Orbiter Mission

  • Last time on SciByte
  • SciByte 107 | Dinosaurs & Satellites (October 29, 2013)
  • The Trip to Mars
  • India’s Mars Orbiter Mission (MOM) safely injected into its initial elliptical Earth parking orbit on Nov. 5
  • India’s PSLV rocket is not powerful enough to send MOM on a direct flight 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
  • The goal is to gradually maneuver MOM – India’s 1st mission to the Red Planet – into a hyperbolic trajectory so that the spacecraft will
  • The spacecraft was initial in an elliptical orbit around Earth, it then proceeds to fire its engines when it is at its closest point in orbit above Earth.
  • 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
  • They expected to achieve escape velocity on Dec. 1 and depart Earth’s sphere of influence tangentially to Earth’s orbit to begin the 300 day (10 month) voyage to Mars
  • Estimates are that it will arrive in the vicinity of Mars on September 24, 2014
  • Small Glitch
  • During a fourth repositioning, on Mon Nov 11, that was to take it 100,000 kilometres (62,000 miles) from Earth, the thruster engines briefly failed, leading the autopilot to take over.
  • The supplemental burn on Nov 12 successfully raised it to the proper orbit
  • The Other Mars Mission
  • NASA\’s MAVEN orbiter remains on target to launch on Nov. 18 – from Cape Canaveral, Florida
  • It\’s goal is to \”Study the Martian atmosphere , unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost\”
  • Both Mission Goals
  • The main aim of MOM is to detect methane in the Martian atmosphere, which could provide evidence of some sort of life form
  • Both MAVEN and MOM’s goal are to study the Martian atmosphere
  • MOM science teams have said they will “work together” with NASA\’s MAVEN team to unlock the secrets of Mars atmosphere and climate history

— CURIOSITY UPDATE —

  • Warm Reset
  • NASA\’s Mars rover Curiosity experienced an unexpected software reboot (also known as a warm reset) on the 7th
  • During a communications pass as it was sending engineering and science data to the Mars Reconnaissance Orbiter, for later downlinking to Earth
  • occurred about four-and-half hours after new flight software had been temporarily loaded into the rover\’s memory
  • At the time the event occurred, Curiosity was in the middle of a scheduled, week-long flight software update and checkout activity
  • A warm reset is executed by flight software when it identifies a problem with one of its operations
  • The reset restarts the flight software into its initial state. Since the reset, the rover has been performing operations and communications as expected
  • This is the first time that Curiosity has executed a fault-related warm reset during its 16-plus months of Mars surface operations

SCIENCE CALENDAR

Looking back

  • Nov 16, 1972 : 41 years ago : Skylab III : Skylab III, carrying a crew of three astronauts, was launched from Cape Canaveral, Fla., on an 84-day mission that remained the longest American space flight for over two decades (until Norm Thagard broke it aboard Mir in 1995 and Shannon Lucid, Feb 2002-Sep 2003). The Skylab III crew, Gerald P. Carr, William R. Pogue and Edward C. Gibson, maintained their physical condition by walking treadmills and riding an on-board stationary bicycle. Among the thousands of experiments conducted during this flight, the astronauts took four space walks, including one on Christmas Day to observe the comet Kohoutek. After 1214 orbits, the crew returned to Earth, splashing down on 8 Feb 1974. Skylab 3 | Wikipedia

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

Kepler\’s Last Dance?

  • NASA’s Kepler telescope lost its ability to precisely point toward stars when one of the reaction wheels –devices which enable the spacecraft to aim in different directions without firing thrusters – has failed
  • Launched in 2009, the Kepler mission completed its 3.5-year planned run last year.it monitors some 150,000 sunlike stars in search of transiting planets
  • Reaction Wheels
  • Reaction wheels try to balance the forces from the solar pressure, that’s what forces a wheel to run
  • Last year reaction wheel #2 failed, and now #4 has failed
  • In July 2012 reaction wheel #2 failed, then earlier this year elevated friction was detected in reaction wheel #4, they saw some movement on the wheel but it went back quickly
  • Extending Fuel Supplies
  • They are currently using thrusters to stabilize the spacecraft, and in its current mode, the onboard fuel will last for several months
  • They could extend the fuel to last a period of several years in a “Point Rest State,” where we can park the vehicle
  • Point Rest State is a loosely-pointed, thruster-controlled state that minimizes fuels usage while providing a continuous X-band communication downlink
  • The software to execute that state was loaded to the spacecraft last week
  • There is the possibility of the wheel running in the opposite direction, but running the wheel backward would mean they would need to use more thruster fuel
  • What Lies Ahead
  • The spacecraft needs at least three reaction wheels to be able to point precisely enough to hunt for planets orbiting distant stars, but it might be possible to use the telescope for another purpose that does not require such precise pointing abilities
  • They will continue to analyze the situation to try and get the telescope back online
  • Even if the Kepler spacecraft is unable to make more observations, there are still terabytes of data to pore over with two years of data that has yet to be searched through

Wireless Brain Imaging

  • A new technology is using wireless signals to provide real-time, non-invasive diagnosis of brain swelling or bleeding.
  • The device analyzes data from low energy, electromagnetic waves, similar to the kind used to transmit radio and mobile signals
  • It could potentially become a cost-effective tool for medical diagnostics and to triage injuries in areas where access to medical care, especially medical imaging, is limited
  • The Prototype
  • Engineers fashioned two coils into a helmet-like device, fitted over the heads of the study participants
  • One coil acts as a radio emitter and the other serves as the receiver. Electromagnetic signals are broadcast through the brain from the emitter to the receiver
  • The waves are extremely weak, and are comparable to standing in a room with the radio or television turned on
  • The device\’s diagnoses for the brain trauma patients in the study matched the results obtained from conventional computerized tomography (CT) scans
  • Researchers take advantage of the characteristic changes in tissue composition and structure in brain injuries
  • For brain edema, swelling results from an increase in fluid in the tissue and for brain hematomas, internal bleeding causes the buildup of blood in certain regions of the brain.
  • Because fluid conducts electricity differently than brain tissue, it is possible to measure changes in electromagnetic properties.
  • Then computer algorithms interpret the changes to determine the likelihood of injury.
  • Prototype Testing
  • The researchers tested a prototype in a small-scale pilot study of healthy adults and brain trauma patients admitted to a military hospital for the Mexican Army
  • The study involved 46 healthy adults, ages 18 to 48, and eight patients with brain damage, ages 27 to 70.
  • The results from the healthy patients were clearly distinguishable from those with brain damage, and data for bleeding was distinct from those for swelling
  • Why is it Important?
  • Symptoms of serious head injuries and brain damage are not always immediately obvious, and for treatment, time is of the essence.

Ancient Water Story

  • A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life
  • Before this finding, the only water of this age was found trapped in tiny bubbles in rock and is incapable of supporting life
  • The Water
  • The crystalline rocks surrounding the water are thought to be around 2.7 billion years old. But no-one thought the water could be the same age, until now
  • Using ground-breaking techniques researchers show that the fluid is at least 1.5 billion years old, but could be significantly older.
  • The interconnected fluid system in the deep Canadian crystalline basement that is billions of years old, and capable of supporting life
  • Scientists say the water found in the Canadian mine pours from the rock at a rate of nearly two litres per minute yet don\’t yet know if the underground system in Canada sustains life
  • Hydrogen, Methane, and Life
  • Researchers have analysed water pouring out of boreholes from a mine 2.4 kilometres beneath Ontario, Canada
  • They have found that the water is rich in dissolved gases like hydrogen, methane and different forms – called isotopes – of noble gases such as helium, neon, argon and xenon
  • The amount of hydrogen in the water is similar to that around hydrothermal vents in the deep ocean, where microbial life has been found
  • The hydrogen and methane come from the interaction between the rock and water, as well as natural radioactive elements in the rock reacting with the water
  • These gases could provide energy for microbes that may not have been exposed to the sun for billions of years.
  • What This Means On a Larger Scale
  • The similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the red planet\’s surface

Flipping Genes for Cancer

  • Researchers at Johns Hopkins have identified a gene that, when repressed in tumor cells, puts a halt to cell growth and a range of processes needed for tumors to enlarge and spread to distant sites
  • The work shows for the first time that switching this gene off in aggressive cancer cells dramatically changes their appearance and behavior
  • The team applied the same techniques to several strains of human breast cancer cells in the laboratory, including the so-called triple negative cells
  • Triple-Negative Breast Cancer
  • Triple-negative breast cancer cells tend to behave aggressively and do not respond to many of our most effective breast cancer therapies
  • Cells with suppressed HMGA1 grow very slowly and fail to migrate or invade new territory
  • The team then implanted tumor cells into mice, the tumors with HMGA1 grew and spread to other areas, such as the lungs, while those with blocked HMGA1 did not grow well in the breast tissue or spread to distant sites.

Sound Pictures of Your Car

  • Researchers have created a camera that creates a heat map-like view of machinery, or anything else
  • 30 digital microphones and a high-res camera pick up on what\’s making noise, and an image shows the different levels of noise, organized by a color gradient with blue meaning a little noise, and red is the most extreme level.
  • While this is not the first sound camera, at about 4 pounds it is one of the most portable

Space Station Patch

  • Peter Daintree / \”Korlus\” – Check This Out!
  • Space Station ammonia Leak and Fix
  • Answer
  • Expedition 35 Flight Engineers inspected and replaced a pump controller box on the International Space Station’s far port truss (P6) leaking ammonia coolant
  • Coolant Pump
  • The device contains the mechanical systems that drive the cooling functions for the port truss.
  • The ammonia cools the 2B power channel, one of eight power channels that control the all the various power-using systems at the ISS
  • While the coolant is vital to the operation of the ISS for the electricity-supplying systems, the crew was not in any danger
  • The Fix
  • The spacewalk is the 168th in support of the assembly and maintenance of the space
  • While astronauts on the station prepared in space, Astronauts at NASA’s Johnson Space Center used the Neutral Buoyancy lab – a 12- meter (40 ft.) deep swimming pool with mockups of the space station that simulates the zero-gravity conditions in space – going through the entire expected EVA
  • A little more than 2 1/2 hours into the spacewalk removed the 260-pound pump controller box from the P6 truss and replaced it with a spare that had been stowed nearby
  • What Happened in the \”Down Time\”
  • All the systems that use power from the 2B channel, the problem area, were transferred throughout the day to another channel
  • The 2B channel will eventually shut down when the coolant is depleted, and the power is being diverted in order to keep everything up and running on the station

More Habitable Zone Exoplanets

  • Astronomers have announced that they have found three new, potentially rocky, planets in the habitable zone of their stars by analyzing nearly three years’ worth of data
  • Kepler Space Telescope
  • As of April 2013, Kepler data has uncovered more than 2,700 potential planets, with about 120 of them having been confirmed to date
  • Mission scientists expect that more than 90 percent of the planets detected are real and not illusions in the data
  • Until now planets in the habitable zone were discovered by what is known as the radial velocity method, which gives a lower limit for the planet’s mass, but no information about its radius
  • While a small radius (less than 2 Earth radii) is a strong indicator that a planet around is indeed rocky it is difficult to assess whether or not a planet is rocky, like the Earth.
  • Finding planets in the habitable zones of larger stars is harder because those planets have relatively long orbits and barely cast a shadow as they pass across the faces of their suns
  • Kepler-62
  • Kepler62 is a red dwarf star, about two-thirds the size of the sun and several hundred degrees Celsius cooler
  • It is only 20 percent as bright as the sun and is about 1,200 light years away and contains five planets currently identified
  • Two of the worlds, Kepler-62e and Kepler-62f are the smallest exoplanets yet found in a habitable zone, and they might both be covered in water or ice, depending on what kind of atmosphere they might have
  • Life on these worlds would be under water with no easy access to metals, to electricity, or fire for metallurgy
  • The biggest uncertainty right now is about both planets composition, early evidence suggests that at least 62f is rocky
  • Kepler-62e and Kepler-62f would exhibit distinctly different colors and make our search for signatures of life easier on such planets in the near future
  • Kepler-62e
  • Orbit is 122 days
  • 1.6 times the diameter of Earth
  • Kepler-62e would have a bit more clouds than Earth according to computer models to sustain an ocean
  • An astronomer at the University of Washington not involved in the research says that Kepler-62e may be too close to its star – and therefore too hot – to sustain life
  • If 62e is a rocky planet, it’s almost certainly tidally locked with its star, half of its surface always facing the star, and the other always facing away
  • Kepler62-f
  • Orbit is 267 days
  • 1.4 times the diameter of Earth
  • Kepler-62f would need the greenhouse effect from plenty of carbon dioxide to warm it enough to host an ocean
  • Kepler-69 System
  • Kepler-36 is a sun-like star located 2,700 light-years away,
  • The Kepler-69 system contains one known planet in that star\’s habitable zone
  • Kepler-69c
  • 1.7 times bigger than Earth, sits on the inner edge of the habitable zone and is almost certainly a super-Venus rather than a super-Earth
  • Habitable Zone Types
  • The \”empirical habitable zone\” is where liquid water can exist on the surface of a planet if that planet has sufficient cloud cover
  • The \”narrow habitable zone\” is where liquid water can exist on the surface even without the presence of a cloud cover
  • Of Note
  • According to the Planetary Habitability Laboratory, there are now nine potential habitable worlds outside of our solar system, with 18 more potentially habitable planetary candidates found by Kepler waiting to be confirmed
  • Astronomers predict there are 25 potentially habitable exomoons
  • Kepler cannot search for signs of life on worlds like Kepler-62e, Kepler-62f and Kepler-69c, but the telescope is paving the way for future missions that should do just that
  • Next-generation missions like the Transiting Exoplanet Survey Satellite, which NASA approved earlier this month for launch in 2017, will take on the task of finding nearer planets that astronomers can study in depth

New Possible Diabetes Treatment Option

  • Researchers have discovered a hormone that holds promise for a dramatically more effective treatment of type 2 diabetes and believe that the hormone might also have a role in treating type 1, or juvenile, diabetes
  • Type 1 Diabetes
  • While betatrophin primarily as a treatment for type 2 diabetes, it is believed it might play a role in the treatment of type 1 diabetes as well
  • Perhaps boosting the number of beta cells and slowing the progression of that autoimmune disease when it\’s first diagnosed
  • Type 2 Diabetes
  • Type 2 diabetes is usually caused by a combination of excess weight and lack of exercise and causes patients to slowly lose beta cells and the ability to produce adequate insulin
  • Provide this hormone, the type 2 diabetic will make more of their own insulin-producing cells, and this will slow down, if not stop, the progression of their diabetes
  • Betatrophin
  • The hormone, called betatrophin, causes mice to produce insulin-secreting pancreatic beta cells at up to 30 times the normal rate
  • In addition the new beta cells only produce insulin when called for by the body, offering the potential for the natural regulation of insulin
  • The researchers know that the hormone exists in human plasma; betatrophin definitely exists in humans
  • The Research
  • The team wasn\’t just looking at what happens when an animal doesn\’t have enough insulin, they were able to find this a gene that had largely gone unnoticed before
  • Another hint came from studying what happens during pregnancy, when there are more beta cells needed, and it turns out that this hormone goes up
  • When a woman gets pregnant, her carbohydrate load, her call for insulin, can increase an enormous amount because of the weight and nutrition needs of the fetus
  • The Future
  • Betatrophin could be in human clinical trials within three to five years, an extremely short time in the normal course of drug discovery and development
  • If it works as they hope it will it could eventually mean that instead of taking insulin injections three times a day, you might take an injection of this hormone once a week or month, or even year
  • The researchers who discovered betatrophin caution that much work remains to be done before it could be used as a treatment in humans

Soaking up Venom in Blood

  • A tiny sponge camouflaged as a red blood cell could soak up toxins ranging from anthrax to snake venom, new research suggests
  • Bacteria and Poisons
  • One of the mainstay strategies of bacteria and poison is to poke holes in cells, disrupting their internal chemical balance and causing them to burst
  • So far, researchers haven\’t had much success creating all-purpose treatments to exploit this vulnerability
  • Nanosponges
  • Researchers created a tiny spherical core of a lactic acid byproduct, which forms naturally during metabolism in the human body
  • To get the outer skin of red blood cells, they used a difference in particle concentration inside and outside the cells to cause them to burst, and then collected their outer membranes
  • They then wrapped the cores in the outer surface of the red blood cell
  • The nanoparticles, also called nanosponges, act as decoys that lure and inactivate the deadly compounds
  • The entire ensemble became a tiny nanosponge, which was about 85 nanometers in diameter, or 100 times smaller than a human hair
  • The sponges\’ tiny size means a small amount of blood, for camouflage, can be used to make an effective dose
  • In cell cultures, the camouflaged sponges act as decoys, luring the toxins from the bacteria that causes strep throat and bee venom
  • The toxins then bind to the structure the \”poisons\” normally use to poke through cells
  • When they stick onto the nanosponge, that particular damaging structure gets preoccupied, since the sponges are so small they can circulate freely through blood vessels, and then the body can digest the entire particle
  • Experiment
  • The team injected 18 mice with a lethal dose of a MRSA, Methicillin-resistant Staphylococcus aureus, toxin. Half the mice then got a dose of the nanosponges
  • Whereas all the mice in the control group died, all but one that received the treatment survived
  • When injected into mice, the tiny decoys protect mice against lethal doses of a toxin produced by methicillin-resistant Staphylococcus aureus, or MRSA.
  • The Future
  • The researchers want to see whether the method works in human blood, and against other toxic chemicals, such as scorpion venom and anthrax, which use similar attack strategies
  • Because so many bacteria use the same pore-forming strategy, the nanosponges could be used as a universal treatment option when doctors don\’t know exactly what is causing an illness

Water in Jupiter\’s Clouds

  • How Did It Get There?
  • In July 1994, the comet Shoemaker-Levy 9 plowed into Jupiter leaving behind millions of gallons of water.
  • Water from the impact still makes up at least 95 percent of the water in the planet’s upper atmosphere
  • Telescopes had previously spotted water in Jupiter’s upper atmosphere, some 100 kilometers above the planet’s ammonia cloud tops, but those surveys could not determine where the water came from
  • Now astronomers have created a high-resolution map of water vapor distribution throughout Jupiter’s atmosphere
  • They found that the concentration of water peaked in the planet’s southern hemisphere, right in the region where the comet struck
  • More water also appeared at higher altitudes around the planet, which supports the comet as its origin.
  • Water from other sources such as Jupiter’s icy moons would likely spread out more evenly around the planet and would gradually filter down to lower altitudes

MarsOne and Life on Mars and Science

  • Mars colony project will do its best to avoid disturbing potential Red Planet life rather than aggressively hunt it down
  • Science and Life
  • The Netherlands-based nonprofit Mars One opened its astronaut-selection process on April 22
  • They plan to land four people on the Red Planet in 2023 to make a permanent human colony on the Red Planet, with new crews arriving every two years thereafter
  • Human explorers will doubtless contaminate whatever site is chosen for the settlement, so the organization will try to pick a place unlikely to host indigenous life to localize the pollution
  • Mars One is working with experts to minimize the risks its colonization effort may pose to potential Red Planet lifeforms
  • While Mars One hasn\’t picked a precise location for its settlement yet, the organization is targeting a swath of the Red Planet between 40 and 45 degrees north latitude
  • Mars One astronauts will not necessarily be scientists
  • Anyone over the age of 18 is eligible to apply, with the selection committee prizing traits such as intelligence, resourcefulness, determination and psychological stability over academic background
  • Science is not the main focus of what we are doing; although, crewmembers will take some scientific gear with them
  • Mars One officials won\’t dictate what the experiments should be, but there will be a budget for equipment that they want to take for scientific research

  • What Happened?
  • An automatically generated report arrived from NASA\’s Robotic Conjunction Assessment Risk Analysis (CARA) team based at NASA\’s Goddard Space Flight Center was sent to the FERMI team just one week away from an unusually close encounter with Cosmos 1805, a defunct spy satellite dating back to the Cold War.
  • The two objects, speeding around Earth at thousands of miles an hour in nearly perpendicular orbits, were expected to miss each other by a mere 700 feet
  • An update days later indicated the satellites would occupy the same point in space within 30 milliseconds of each other
  • Using thrusters for use at the end of Fermi\’s operating life designed to take it out of orbit and allow it burn up in the atmosphere they were able to adjust the orbit just slightly enough to evade a collision
  • The U.S. Space Surveillance Network continues to keep tabs on every artificial object larger than 4 inches across in Earth orbit. Of the 17,000 objects currently tracked, only about 7 percent are active satellites

New Atlantis Exhibit Prep

  • The Space shuttle Atlantis is set to go on public display June 29 at NASA\’s Kennedy Space Center Visitor Complex in Florida
  • Shuttle Reveal
  • It was revealed Friday, April 26 after workers spent two days peeling off its protective shrink-wrap cover of the past five months.
  • Workers began carefully cutting back the 16,000 square feet (1,486 square meters) of shrink wrap that protected Atlantis as its $100 million exhibition building was completed around it
  • By the end of the first day, the shuttle\’s nose, tail, aft engines and left wing were exposed, the workers completed the process the next day, revealing Atlantis\’ right wing and its 60-foot-long (18 meter) payload bay
  • Opening the payload bay is set to begin in May, will take about two weeks, as the doors are very slowly hoisted open, one by one.
  • Atlantis has been mounted. Thirty feet (9 meters) in the air, the space shuttle has been tilted 43.21 degrees, such that its left wing extends toward the ground.
  • Atlantis will appear to be back in space – an effect that will be enhanced by lighting and a mural-size digital screen that will project the Earth\’s horizon behind the shuttle

Runaway planets

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

Lego’s can help build bones too

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

Sorry some coffee lovers

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

  • Albert Einstein’s complete archive is gradually becoming available through the Einstein Archives Online
  • The archive when fully uploaded will have more than 80,000 documents.
  • The archive will contain everything from manuscripts containing the famous E=mc^2 equation written in Einstein’s handwriting to postcards to his mother

You could bring about the next great Hubble picture

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

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

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

  • 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.

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 Exoplanet and Exomoon News keeps coming

  • The exoplanet low down
  • The Hungarian-made Automated Telescope Network (HATNet) Project, one of the goal of the HATNet project is to detect and characterize extrasolar planets using the transit method
  • I believe the HATNet network telescopes are now deployed in : Budapest, Hungary; Arizona; United States, Negev Desert, Israel; New South Wales, Australia; Gamsberg, Namibia; Santiaho, Chile
  • As 2011 ended, there were a total of 716 confirmed exoplanets and 2,326 planetary candidates
  • Four more planets have already been discovered this year, not by Kepler but by a ground based telescope network who has already discovered 29 other extrasolar planets
  • All four are ‘hot Jupiter’ type planers with ‘years’ from 1–5.5 days long. In comparison Mercury takes 88 days.
  • SETI (Search for Extraterrestrial Intelligence) program will take a look at the exoplanets discovered by Kepler in the continuing search for alien radio signals
  • Based on early Kepler data, the new estimates for the number of exoplanets have billions of planets in our galaxy alone
  • They now have can now focus on systems with planets
  • * Of Note for Exoplanets*
  • Runs Linux : The ground based exoplanet searching network, HATNet, is controlled by a single Linux PC without human supervision.
  • Data for the HATNet is stored in a MySQL database
  • SETI has even joined in the exoplantest search, and has seen a few ‘interesting’ signals, but are most likely interference from the Earth
  • The exomoon low down
  • Current technology may be able to detect Large Earth-size moons
  • There are currently three different mechanisms that scientist believe would cause an Earth sized moon
  • form together with it’s planet in the accretion disk
  • massive impact, like the theory of our moons formation. Estimates currently say might be as frequent as 1 in 12 could be formed this way and are expected to only contain roughly 4% of the total mass of the planet
  • an Earth sized object would also be captured by a gas giant. Simulations show that around 50% of captured objects would survive
  • Such moons could be detected using the detected wobble of the star, this has already been measured with planets of similar size. There already simulations for trinare stars which could be altered to analyze a sun-planet-moon scenario.
  • The first exoplanets discovered were found around a pulsar, causing cariations in the regular pulsations.
  • Pulsars often beat thousands of times a minute which makes them extremely sensitive to gravitational affects of planets and possibly moons.
  • In the past few years it has become possible for direct imaging of planets, although planets near Earth sized is likely a few fear off, possible upcoming missions may make that possibility a reality.
  • Direct imaging may be no more than a slightly offset center of a dot, or a barely oblong circle indicating a possible moon.
  • * Of Note for exomoons*
  • There are no moons in our own solar system of the necessary size for detection by typically used technology, the largest moon in our solar system (Ganymede) is only 40% the diameter of the Earth
  • Using technology for use on pulsars a planet a mere 0.04% the mass of the Earth has been discovered.
  • The same technology that could be used to detect exomoons could also be used to detect unique data signals that would indicate Saturn-like rings around stars.
  • Significance
  • Each year the technology for discovering exoplanets increases, we are now entering the ability to detect exomoons.
  • The possibilities of seeing details in other solar systems will increase our understand of how solar systems and planets form.

Lunar Minerals found

  • The low down
  • When the lunar samples first returned from the Moon there were subjected to rigorous study and considered extremely precious.
  • In the hundreds of pounds of lunar rocks astronauts brought back three minerals were unique to the moon: armalcolite, pyroxferroite and tranquillityite
  • Armalcolite and Pyroxferroite were both found on Earth in the 70’s
  • Tranquillityite had previously been found in certain meteorite, but not naturally on the Earth.
  • Tranquillityite is shaped like tiny needles that have been pounded flat and are unusually small, less than the diameter of the thickest human hair (about 150 micrometers )
  • Tranquillityite develops during the late stages of crystallization of molten rocks in oxygen-poor conditions
  • Significance
  • Tranquillityite has just been found in Australia
  • In fact it has now been found in six widely scattered sites in Western Australia suggests that it might be more common than thought in igneous rocks
  • The identification of all minerals found in the Lunar samples brought back from the Moon during the Apollo program lends credence to the impact theory for the Moons creation
  • * Of Note*
  • It’s not surprising that tranquillityite hasn’t shown up until now as it is unstable over the long term at Earth’s surface
  • In addition tranquillityite can easily be mistaken for another similarly colored mineral

Dogs know when your not looking

The low down

  • An new study proves what all dog owners already knew
  • The study shows that dogs will follow the gaze of humans, even on television screens, and can recognize when they look to one side or another, not even something primates can do
  • Significance
  • In this study 22 different dog breeds were used, all performed fairly similarly
  • A stranger on a TV screen would say “hi, dog!” in either a high- or low- pitched voice and either looking at the screen or down.
  • In any instance the person would then look at the pot that contains a toy for 5 seconds
  • When the person on the screen avoided eye contact and spoke in a low voice the likely hood that the dogs would look at one pot over the other was a statistical wash
  • When a high pitched-pitched voice was used the dog looked at the person on the screen 69% of the time.
  • Future studies could compare different dog breeds and various ages with each other as the next stage in the experiment
  • The results from this study were also nearly identical to those seen in 6-month-old human infants
  • Some researchers even say that dog social skill can reach the level of a two-year-old human, missing only language
  • In another study done in 1994 a 19-year-old apprentice working at a chimpanzee center was assisting in a study on primate behavior that he claimed his dog did. he was told to prove it
  • He devised a simple experiment in his garage hid treats under cups when a dog wasn’t looking then either pointed or simply looked at the cup containing the treat
  • * Of Note*
  • In studies analyzing the ability to follow a person’s pointing finger or the direction of his gaze, dogs perform better than primates
  • However dogs are less likely to inhibit a learned response than primates
  • There are research teams that suspect that horses and domesticated cats may also be able to read human intent, since they too have lived closely with us for many years.
  • Both children and animals are more likely to respond to a high-pitched voice, which explains why we naturally tend to ‘baby-talk’ animals and young children
  • This experiment also gives you a scientific excuse to do this the next time you get funny looks from people

Neutrinos strike again!

The low down

  • Physicists at the Chinese Academy of Sciences’ Institute of High Energy Physics in Beijing now argue that Neutrino’s could not travel faster than the speed of light, as it would not only mess up Einstein’s theory of special relativity, but also the last of conservation of energy and momentum
  • Significance
  • Both studies claim that the particles, called pions, could not possibly have had enough energy to give rise to the faster-than-light, or superluminal, speeds indicated by OPERA.
  • The new team of physicists calculate that achieving the velocities measured required pions with energies 20 times greater than their offspring
  • The team says that the IceCube detector at the South Pole has measured these neutrinos to energies more than 10,000 times as high as OPERA’s neutrinos
  • They also say with a neutrinos near zero, but not zero, mass there should be a limit to how fast they can travel.

The anti-alcohol drug that lessens hangovers too?

The low down

  • Scientists have been surveying herbal compounds that supposedly have reduced alcohol affects
  • Once such candidate was from the seeds of the Asian tree Hovenia dulcis, first said to be an excellent handover drug in 659 [That’s 1,352 years ago]
  • The team of scientists focused on one ingredient of the Hovenia dulcis tree, called dihydromyricetin, or DHM, on rats, which responds to alcohol in similar ways as humans
  • Significance
  • Rats given the equivalent of 15–20 beers in under two hours tolerated the alcohol better, with a stupor lasting around an hour, with DHM the stupor lasted only 15 minutes
  • A dose of DHM also helped ease hangover symptoms, reducing anxiety and susceptibility to seizures
  • Althought these results are promising, it still won’t allow you to drink like you were breathing air, as alcohol has many affects on the brain and DHM seems to only curb some of these affects
  • * Of Note*
  • The most promising result is that rats given access to alcohol gradually start consuming more, while rats drinking DHM-laced alcohol did not increase consumption
  • This seems to indicate that DHM might be a promising weapon to use against Alcohol addiction

  • After 19 attempts over 51 years, Russia has yet to have a fully successful mission to Mars.
  • Also one of five high-profile failures for the Russian space program in 2011.
  • The Russian chief of the Russian space program has hinted that the recent unlucky Russian space program may be the fault of ‘foreign power’
  • Significance
  • The last Russian Program Chief was fired after three navigation satellites were lost during launch
  • Russian Space Program Chief says that the vessels setbacks have occurred flying through Russia’s blind spot where they can not see or receive telemetry readings
  • The current Program Chief does admit that the mission was risky and underfunded, with original designs date back to the Soviet Union
  • He also admits that the launch window was limited and if they didn’t launch during the window, they would have to write off $160 million / 125.5 million Euro’s / five billion rubles
  • * Of Note*
  • This won’t be the first time that the Alaskan radar station, last November it was blamed for the failure of the Phobos-Grunt by un-named retired Russian General (previously in charge of Russia’s early warning system)
  • HAARP does perform active and passive radar experiments on the ionosphere
  • However, personnel at HAARP said a full-power blast would have kissed the Phobos-Grunt rocket with the equivalent of pointing a 60-watt light bulb at it from about 69 feet away. [about 1.03 milliwatts of radio energy per square centimeter ]
