Woolly Mammoth Blood!?!?!?

  • The Wooly Mammoth
  • An expedition led by Russian scientists earlier this month uncovered the well-preserved carcass of a female mammoth on a remote island in the Arctic Ocean
  • The head of the expedition, said the animal died 10,000 to 15,000, at the age of around 60 some, making it the first time that an old female had been found
  • Wooly mammoths are thought to have died out around 10,000 years ago
  • Scientists think small groups of them lived longer in Alaska and on Russia\’s Wrangel Island off the Siberian coast.
  • The Claim on the Body Preservation
  • The lower part of the carcass was very well preserved as it ended up in a pool of water that later froze over
  • The upper part of the body including the back and the head are believed to have been eaten by predators
  • The team was surprised that the carcass was so well preserved that it still had blood and muscle tissue, and that when they broke the ice beneath the stomach, very dark blood flowed out
  • The muscle tissue is also said to be red, the colour of fresh meat
  • The temperature at the time of excavation was -7 to – 10 degrees Celsius [19.4 to 14 degrees Fahrenheit]
  • Because these temperatures are below freezing it may be assumed that the blood of mammoths had some cryoprotective properties
  • To Be Studied
  • If these claims are true, it will be the most well-preserved tissue found from a Woolly Mammoth
  • Mammoth specialists from South Korea, Russia and the United States are expected to study the remains which the Russian scientists are now keeping at an undisclosed northern location
  • \”Jurassic Park Prize\”
  • Scientists already have deciphered much of the genetic code of the woolly mammoth from balls of mammoth hair found frozen in the Siberian permafrost
  • The discovery gives researchers a really good chance of finding live cells which can help in cloning a mammoth
  • Last year the researchers signed a deal with cloning pioneer Hwang Woo-Suk of South Korea\’s Sooam Biotech Research Foundation, who in 2005 created the world\’s first cloned dog.
  • Those who succeed in recreating an extinct animal could claim a \”Jurassic Park prize\”, the concept of which is being developed by the X Prize Foundation

University Rover Challenge

  • What is the University Rover Challenge?
  • The competition is hosted by the Mars Society, a non-profit research organization dedicated to promoting the exploration and eventual settlement of Mars
  • The competition site is located at the society\’s Mars Desert Research Station (MDRS), a rocky barren landscape that\’s similar to Martian terrain
  • Each team was allowed to spend up to $15,000 on their rovers, which can weigh no more than 50 kilograms – about 110 lbs.
  • The URC is based on the assumption that the rovers are telerobots, which means they would be operated by astronauts on or orbiting Mars
  • Team members must guide their rovers via a remote connection, such as a computer in the back of a truck, as long as it\’s shielded so the team can\’t see their rovers
  • Teams compete in four challenges, which change year to year, designed to replicate the activities of NASA\’s rovers on Mars.
  • The Tasks for 2013
  • Teams will guide their rovers to collect the subsurface soil samples most likely to contain photosynthetic bacteria, lichen and other bits of living material
  • Deliver a series of packages, such as emergency supplies to \”astronauts\” (URC staff) in the field
  • Fix a dust-covered solar panel (without water, of course)
  • Navigate an obstacle course that will include climbing steep grades, getting over boulders and passing through PVC pipe gates, aimed to test each rover\’s maneuverability
  • The Teams
  • This year\’s teams represent universities and colleges in Canada, India, Poland and the United States
  • These include two-time returning champions Toronto\’s York University (2012 and 2009) and Oregon State (2010 and 2008)
  • Full list of entries for the 2013 URC
  • Winners
  • First Place with 493 out of 500 points (highest ever scored) | The Hyperion Team from Bialystok University of Technology, Poland
  • Second Place with 401 out of 500 points | Scorpio 3 team from Wroclaw University of Technology, Poland

Conductive Paint

  • What Is It?
  • The substance allows the painting of \”liquid wiring\” on any surface, except for skin
  • Radio Shack stocks paint pens, which the inventors emphasized, is the first non-toxic electrically conductive paint available and it dries at room temperature
  • The inventors also say that they hope to appeal to a wide creative range of hobbyists, artists, and engineers for innovative ways to use their products
  • In addition the substance is child friendly, which opens the door to educational projects, including toys, and touch-sensitive paper drawings that play sounds
  • Applications
  • Generally split into two simple classifications, signaling and powering
  • Signaling could include using the Paint as a potentiometer while interfacing with a micro-controller, as a conduit in a larger circuit or as a capacitive sensor
  • Powering a device would include lighting LED\’s or driving small speakers
  • According to the company, Bare Paint has a surface resistivity of approximately 55 ohms/square at 50 microns layer thickness (human hair is ~100 microns)

Crowdsourced Telescope

  • A commercial asteroid-mining company aiming to launch a crowdfunded space telescope raised more than $200,000 on the first day of its campaign
  • Total raised by the morning of filming this show (June 3) $714,473
  • The Plan
  • Planetary Resources, a private venture aiming to mine near-Earth space rocks announced on May 29 that it would build and launch a space telescope for public use if it could raise at least $1 million in 33 days.
  • The telescope will be a twin copy of the Arkyd spacecraft the company is developing to detect, track and study asteroids in preparation for its mining mission
  • A test version of the spacecraft is set for its maiden trial flight in April 2014, while the crowdfunded model would launch in early 2015
  • What the Backers Get
  • Public backers would use it to study celestial objects of their choice, they also have the option of sponsoring research projects at schools, universities or museums that could use the instrument.
  • The telescope will also take self portraits that show the telescope in orbit, with a user-submitted photo displayed on the instrument\’s screen, a camera mounted on the hull of the spacecraft will snap the photo.
  • Where Does the Name \”ARYKD\” Come From?
  • To some Star Wars fans, it might sound familiar
  • In the start of the project while looking for a code name the idea was to make a derivation of Arakyd Industries from the Star Wars universe
  • According to the StarWars.wikia : \”Arakyd Industries was a major manufacturer of droids, heavy weapons, and starships, dating back to the days of the Galactic Republic\”
  • They made such things as the Viper probe droid model, which the Empire used to locate the Echo Base on the planet Hoth
  • The Viper probe droids themselves were based on earlier probe droids that were the first true probe droids to search planets and asteroids for valuable resources, such as metals to fuel the processing plants of industry
  • Other Random/Interesting Facts
  • The space shuttle had room for 1 Hubble Space Telescope in its payload bay, it could have fit 1,000 ARKYD Space Telescopes
  • Going at 5 mi/sec it will travel 8x faster than an SR-71 Blackbird flying at mach 3, that\’s going from San Francisco to Boston in 10 min
  • At those speeds it will have a few min each orbit to download information at DSL speeds, the primary/first ground station will be in Seattle
  • Once the mission is going it will take 150 \”selfies\” and make 15 astronomical observations per day
  • It will run off of only 50 W, the same amount as a standard household light … or 111 hamster wheels
  • ARYKD Dimensions
  • Weight : 15 kg / 33 lb
  • Height 200 mm / 7.8 in
  • Wingspan Deployed : 600 mm / 23.6 in
  • Peak Power : 50 W

Frozen Moss, Back to Life

  • Zombie Moss?
  • Scientists have recently found that even after hundreds of years buried under ice, mosses can regrow
  • The revived plants come from Canada’s Ellesmere Island, where the Teardrop Glacier has retreated since the end of a cold period in 1550 to 1850 known as the Little Ice Age
  • On recently exposed ground they found clumps of mosses that looked dead. But among the brown tangles, the team noticed a few green sprigs
  • The team took brown moss samples back to the lab and used radiocarbon dating to determine that they had lived about 400 years ago
  • Based on the glacier’s retreat rate, the researchers estimated the plants had been uncovered for less than two years.
  • The team then ground up some of the plants and gave them nutrients, water and light
  • From seven of 24 samples, a total of four moss species grew
  • The budding plants didn’t come from seeds or spores because in moss, any cell can be reset, almost like a stem cell, to grow a new plant
  • How long a moss cell can stay viable is “anyone’s guess,”
  • The findings suggest that the regenerated mosses may help repopulate ecosystems after glaciers retreat

EyeSpy an Exoplanet!

  • The Hubby | Check This Out! | Exoplanet Directly Observed
  • A newly discovered gaseous planet has been directly photographed orbiting a star about 300 light-years from Earth
  • Only a few planets have been directly observed so far, and this world may be the least massive planet directly observed outside of the solar system
  • The Planet
  • The photo released by the European Southern Observatory (ESO) on June 3 depicts the suspected gas giant (called HD 95086 b) circling its young star (named HD 95086) in infrared light
  • The planet was discovered by ESO\’s Very Large Telescope in Chile. Based on the planet\’s brightness, scientists estimate that it is only about four or five times more massive than Jupiter
  • The planet orbits its star at about twice the distance from the sun to Neptune and about 56 times the distance between Earth and the sun, the blue circle in the photo represents the distance between the sun and Neptune.
  • The star is relatively young, at only 10 million to 17 million years old, making the formation of the exoplanet and the dusty disc surrounding the star potentially intriguing to researchers
  • Formation
  • The planet might have grown by assembling the rocks that form the solid core and then slowly accumulated gas from the environment to form the heavy atmosphere
  • It also might have started forming from a gaseous clump that arose from gravitational instabilities in the disc
  • Interactions between the planet and the disc itself or with other planets may have also moved the planet from where it was born

— SPACECRAFT UPDATE—

Lunar Gravity Map

  • Mascons
  • Mascons, or gravitational anomalies, were discovered on the moon in the 1960s, as NASA officials were planning for the Apollo moon missions, but the cause of these anomalies was unknown
  • By mapping the moon\’s gravity field, the Grail probes uncovered the locations of lunar mascons, and offered unprecedented views of the moon\’s interior structure
  • This enabled scientists to study two basins – one on the lunar nearside and one on the far side of the moon – to develop sophisticated computer models for how mascons form
  • New Ideas How They Formed
  • Billions of years ago, massive asteroids that collided with the moon left deep craters that reached into the mantle material that lies beneath the thin lunar crust
  • What had been unexplained until now was how these big impact sites could support extremely dense material, and how the gravity field in these basins could be in such disequilibrium
  • Mascon basins on the near side of the moon were partially filled in with ancient flows of dense lava, which seemed able to account for the mass excess and positive gravity anomalies
  • For some basins, however, the observed lava flows were too thin to explain the mass excess, some basins were even found that exhibited mascons but lacked lava infill altogether
  • The researchers determined that ancient asteroid impacts excavated large craters on the moon, causing surrounding lunar materials and rocks from the moon\’s mantle to melt and collapse inward
  • This melting caused the material to become denser and more concentrated than the strong lunar crust, which also slides down into the impact hole, eventually forms a curved but rigid barrier over the basin, holding the dense materials down
  • New models from this data gave the researchers a glimpse of how the moon\’s mascons formed in the aftermath of huge asteroid impacts

— CURIOSITY UPDATE —

  • Radiation Findings
  • Curiosity\’s Radiation Assessment Detector (RAD) is the first instrument to measure the radiation environment during a Mars cruise mission from inside a spacecraft that is similar to potential human exploration spacecraft
  • The findings,indicate radiation exposure for human explorers could exceed NASA\’s career limit for astronauts if current propulsion systems are used.
  • Forms of Radiation
  • GCR\’s. Galactic cosmic rays are particles caused by supernova explosions and other high-energy events outside the solar system.
  • SEP\’s. Solar energetic particles are associated with solar flares and coronal mass ejections from the sun
  • Radiation Exposure
  • NASA has established a three percent increased risk of fatal cancer as an acceptable career limit for its astronauts currently operating in low-Earth orbit
  • Only about three percent of the radiation dose was associated with solar particles because of a relatively quiet solar cycle and the shielding provided by the spacecraft
  • The radiation detected for the accumulated dose during the trip was about what you would get if you had a whole-body CT scan once every five or six days
  • Shielding
  • Current spacecraft shield much more effectively against SEPs than GCRs. To protect against the comparatively low energy of typical SEPs, astronauts might need to move into havens with extra shielding on a spacecraft or on the Martian surface, or employ other countermeasures
  • GCRs tend to be highly energetic, highly penetrating particles that are not stopped by the modest shielding provided by a typical spacecraft.
  • The Future
  • RAD data collected during Curiosity\’s science mission will continue to inform plans to protect astronauts as NASA designs future missions to Mars in the coming decades
  • Radiation
  • The MSL spacecraft structure (which includes the backshell and heat shield as well as the Curiosity rover and its descent stage) provided significant shielding from the deep space radiation environment
  • The spikes in radiation levels occurred in February, March and late May of 2012 because of large solar energetic particle events caused by solar activity

SCIENCE CALENDAR

Looking back

  • June 6, 1878 : 135 years ago : Liquid air : In 1878, liquid air obtained at a temperature of -192ºC was exhibited by Professor James Dewar at the Royal Institution, London. His work followed the small-scale production of liquid air by Raoul Pictet of Geneva (Dec 1877) and Cailletet of Paris (Jan 1878). In March 1893, Dewar produced solid air. He gave six well-illustrated Christmas Lectures on “Air: gaseous and liquid” at the Royal Institution between 28 Dec 1893 and 9 Jan 1894. (Some of the air in the room was liquefied in the presence of the audience, and remained so for some time, when enclosed in a vacuum jacket.) He demonstrated several physical properties of liquid air, and produced solid air at the Friday 19 Jan 1894 meeting of the Royal Institution

Well preserved mammoth discovered in Siberia



Left Image/Video Credit: BBC YouTube Channel || Right Image/Video Credit: news.bbcimg.co.uk

  • Thanks Peregrine Falcon for making sure I saw this
  • The low down
  • Extinct animals are mostly studied from bones, teeth and tusks, because these parts decompose over a relatively long time
  • Soft tissues like muscle, skin, and internal organs are rarely found on older carcasses because they decompose much quicker
  • Because of this information about a species or specimen is constrained to the slowly decomposing parts, vital information is unavailable
  • Most permafrost-preserved mammoth specimens consist solely of bones or bone fragments that currently provide little new insight into the species’ biology in life
  • Now a remarkably well preserved frozen juvenile mammoth carcass, nicknamed “Yuka,” was found entombed in Siberian ice
  • Although carbon dating is still in the works, it is believed to be at least 10,000 years old, it was found as part of a BBC/Discovery Channel-funded expedition
  • The mammoth was in such good shape that much of its flesh is still intact
  • The skin retained its pink color, and the blonde-red hue of the woolly coat also remains.
  • Significance
  • Yuka is the first mammoth carcass with soft tissues preserved it was also the first to show human interaction in the region
  • The soft tissues actually included strawberry-blonde hair, which could help reveal whether or not mammoths had all of the same hair colors that humans do
  • Analysis of the tusks and teeth researchers estimate that the animal was about 2.5 years old when it died.
  • Healed scratches found on the skin indicate a lion attack that Yuka survived earlier in its relatively short life
  • Judging by deep, unhealed scratches in the hide and bite marks on the tail suggest it was most likely pursued by one or more lions right before its death
  • Based on evidence of a freshly broken leg it probably took a bad fall and broke a lower hind leg
  • Scientists have guessed that the extinct subspecies of the African lion (Panthera leo spelea) were present in the area at the same time as the mammoths, and that they hunted mammoths.
  • Yuka provides fairly solid evidence that that was correct
  • Fifteen to thirty scalloped marks on the skin are an indication of possible saw-like motion of a human tool
  • Humans may have moved in either right before or after it died, suggesting that humans at that time ‘stole’ kills from hunting lions
  • The removed parts that could be of use immediately, and probably buried the rest of the body for possible later use
  • No longer with the animal are the main core mass of Yuka’s body, including the skull, spine, pelvis, organs, vertebrae, ribs, associated musculature, and some of the meat from upper parts of the legs
  • The skull and pelvis were found nearby
  • * Of Note*
  • The scientist to publish the genetic code of mammoth hemoglobin a few years ago
  • Both this specimen and the near complete specimen of a baby mammoth discovered in 2007 will help researchers with genotype (DNA sequences) which could lead the application of cloning to bring a mammoth back to life
  • The ability to bring it back the mammoth from extinction using cloning would probably take years to decades
  • Watch for Woolly Mammoth: Secrets from the Ice on BBC Two at 21:00 BST on Wednesday 4 April and will be shown on the Discovery Channel in the US at a future date.

More Fine Feathered Dinosaurs



Left Image Credit: Zhang Hailong | Right Image Credit: Zhang Hailong

  • * Last time on SciByte*
  • Solar Storms & Higgs Boson | SciByte 37 [March 13, 2012] – More Dinosaur feathers get color
  • Feedback & Space Lego’s | SciByte 31 [Jan 31, 2012] – Dinosaur feather colors
  • The low down
  • New fossils of one adult and two younger dinosaurs show evidence of an extensively feathers dinosaur, the largest species to date
  • The region the new discoveries have been made is well known for keeping soft tissues of ancient animals well-preserved
  • Significance
  • Yutyrannus hauli, Y.huali, a mix of latin and mandarin translated into “beautiful feathered tyrant”, weighed up to about 3,000 lb (1,400 kg) and stretched 30ft (9m) from nose to tail
  • The species had include a high, bumpy nose plate, known as a midline crest and likely stood 8ft (2.5m) tall, although its posture is unknown
  • Y.huali, although differs in growth strategy, has the type of skeletal features that make it in the same family as the Tyrannosaurus Rex, and would have reached T. rex’s chest.
  • The feathers of the Y.Hauli were at least 6in (15cm) long, although the color of the feathers is not known
  • There is some evidence that shows the coverage was a bit patchy which, might have given the dinosaur a shaggy appearance
  • Although its appears that the feathers might have entirely covered the dinosaurs skin, scientists are unable to confirm because the specimens aren’t complete.
  • * Of Note*
  • Some scientists hypothesize that smaller dinosaurs used a fluffy layer of feathers to stay warm
  • Other dinosaur specimens have shown evidence of being fully feathered, however all of those were far have been much smaller
  • Thanks to small surface-to-volume body ratios, large-bodied animals tend to maintain heat easily.
  • This hypothesis further goes on to suggest that the larger species found lost their feathers the bigger they got or were just not as extensively covered.
  • Other scientists point out that in warmer climates animals like the modern giraffes and wildebeests, have external covering but don’t need it for insulation
  • Another hypothesis is that the feathers were simply used to show off and attract mates.
    • Either hypothesis has some scientists reimagining the appearance of the Tyrannosaurus rex, and other dinosaurs

Killing bacteria with plasma

  • The low down
  • Plasma is the fourth state of matter (solids, liquids and gases) has previously shown its worth in the medical industry by effectively killing bacteria and viruses on the surface of the skin and in water.
  • Plasmas are produced in electrical discharges, these gases of free electrons and ions
  • Medical science has high hopes for plasmas. and they have already been shown to destroy pathogens, help heal wounds, and selectively kill cancer cells
  • It seems that the highly reactive oxygen species generated oxidized cell membranes and damage DNA.
  • These oxygen species are also found in our immune system
  • Significance
  • Killing harmful bacteria in hospitals is difficult; out in the field, it can be an even bigger problem
  • Now researchers may have found a remote disinfection in a portable “flashlight” that shines a ray of cold plasma to kill bacteria in minutes.
  • In an experiment the ‘flashlight’ was put over a thick biofilm of one of the most antibiotic- and heat-resistant bacteria which often infects the root canals during dental treatments.
  • Biofilms created in this experiment were incubating bacteria for seven days, and were around 0.0001 in (25 micrometres) thick and consisted of 17 different layers of bacteria.
  • After five minutes of treatment the plasma not only inactivated the top layer of cells, but penetrated deep into the very bottom of the layers to kill the bacteria.
  • * Of Note*
  • Adding to the safety of the device was that the UV radiation in the jet created by the plasma flashlight was so low
  • In addition temperature of the plume of plasma in the experiments was between 20–230C, which is very close to room temperature and therefore prevents any damage to the skin
  • The device now costs less that $100 so produce, before making it ready for commercialisation

SCIENCE CALENDER

Looking back

  • April 11, 1970 : 42 years ago : Apollo XIII Launch : The mission began with a little-known smaller incident: during the second-stage boost, the center (inboard) engine shut down two minutes early. The four outboard engines burned longer to compensate, and the vehicle continued to a successful orbit. The third manned lunar landing mission, was launched from Cape Canaveral with crew James Lovell, Fred Haise, and John Swigert. Swigert was a late replacement for the original CM pilot Ken Mattingly, who was grounded by the flight surgeon after exposure to German measles.
  • April 13, 1970 : 42 years ago : Apollo XIII Rescue : Disaster struck 200,000 miles from earth. A liquid oxygen tank exploded, disabling the normal supply of oxygen, electricity, light, and water. Swigert reported: “Houston, we’ve had a problem.” The lunar landing was aborted. After circling the moon, the crippled spacecraft began a long, cold journey back to earth with enormous logistical problems in providing enough energy to the damaged fuel cells to allow a safe return.
  • April 17, 1970 : 42 years ago : Apollo XIII Return : Apollo 13 landed safely with a splashdown in the Pacific Ocean, four days after the spacecraft aborted its mission while it was four-fifths of the way to the moon. Upon his return, astronaut A. J. Lovell, Jr. was the first American astronaut to travel over 700 hours in space.
