Proposed Indicator of Life On Alien Worlds May Be Bogus 112

Posted by Unknown Lamer
from the exomoons-ruin-everything dept.
sciencehabit (1205606) writes with bad news for anyone hoping to use the spectral signatures of exoplanets to determine if their atmospheres have life-enabling compositions. "Call it the cosmic version of fool's gold. What was once considered a sure-fire sign of life on distant planets may not be so sure-fire after all, a new study suggests. The signal—a strong chemical imbalance in the planet's atmosphere that could only be generated by thriving ecosystems—could instead be the combined light from a lifeless exoplanet and its equally barren moon."

Hugh Pickens DOT Com (2995471) writes "Red Orbit reports that after nearly 50 years of warping across galaxies and saving the universe from a variety of alien threats and celestial disasters, Star Trek's William Shatner was honored with NASA's Distinguished Public Service medal, the highest award bestowed by the agency to non-government personnel. 'William Shatner has been so generous with his time and energy in encouraging students to study science and math, and for inspiring generations of explorers, including many of the astronauts and engineers who are a part of NASA today,' said David Weaver, NASA's associate administrator for the Office of Communications at NASA Headquarters in Washington. 'He's most deserving of this prestigious award.' Past recipients of the NASA Distinguished Public Service Medal include astrophysicist Neil deGrasse Tyson, former NASA Jet Propulsion Laboratory director and Voyager project scientist Edward Stone, theoretical physicist and astronomer Lyman Spitzer, and science fiction writer Robert Heinlein. The award is presented to those who 'have personally made a contribution representing substantial progress to the NASA mission. The contribution must be so extraordinary that other forms of recognition would be inadequate.'"

Male Scent Molecules May Be Compromising Biomedical Research 274

Posted by samzenpus
from the something-doesn't-smell-right dept.
sciencehabit (1205606) writes "Scientists have found that mice feel 36% less pain when a male researcher is in the room, versus a female researcher. The rodents are also less stressed out. The effect appears to be due to scent molecules that male mammals (including humans, dogs, and cats) have been emitting for eons. The finding could help explain why some labs have trouble replicating the results of others, and it could cause a reevaluation of decades of animal experiments: everything from the effectiveness of experimental drugs to the ability of monkeys to do math. Male odor could even influence human clinical trials."

How Concrete Contributed To the Downfall of the Roman Empire 384

concertina226 (2447056) writes "The real reason behind the downfall of the Roman Empire might not have been lead contaminating in the water, which is the most popular theory, but the use of concrete as a building material. Dr Penelope Davies, a historian with the University of Texas believes that the rise of concrete as a building material may have weakened ancient Rome's entire political system as Pompey and Julius Caesar began 'thinking like kings'. Concrete was used to build many of Rome's finest monuments, such as the Pantheon, the Colosseum and the Tabularium, which have lasted the test of time and are still standing today."

The Koch Brothers Attack On Solar Energy 769

Posted by samzenpus
from the there-goes-the-sun dept.
Hugh Pickens DOT Com (2995471) writes "The NYT writes in an editorial that for the last few months, the Koch brothers and their conservative allies in state government have been spending heavily to fight incentives for renewable energy, by pushing legislatures to impose a surtax on this increasingly popular practice, hoping to make installing solar panels on houses less attractive. 'The coal producers' motivation is clear: They see solar and wind energy as a long-term threat to their businesses. That might seem distant at the moment, when nearly 40 percent of the nation's electricity is still generated by coal, and when less than 1 percent of power customers have solar arrays. But given new regulations on power-plant emissions of mercury and other pollutants, and the urgent need to reduce global warming emissions, the future clearly lies with renewable energy.' For example, the Arizona Public Service Company, the state's largest utility, funneled large sums through a Koch operative to a nonprofit group that ran an ad claiming net metering would hurt older people on fixed incomes (video) by raising electric rates. The ad tried to link the requirement to President Obama. Another Koch ad likens the renewable-energy requirement to health care reform, the ultimate insult in that world. 'Like Obamacare, it's another government mandate we can't afford,' the narrator says. 'That line might appeal to Tea Partiers, but it's deliberately misleading,' concludes the editorial. 'This campaign is really about the profits of Koch Carbon and the utilities, which to its organizers is much more important than clean air and the consequences of climate change.'"

An anonymous reader writes in with this bit of news about the Mars rover Curiosity. "NASA's Curiosity Mars rover is using several tools this weekend to take a closer look at a sandstone slab being assessed as a possible drilling target. If it fits the bill, the target could become Curiosity's third drilled rock. 'Windjana,' named after a gorge in Western Australia, would be the mission's first drilled rock that is not mudstone. To determine whether Curiosity should drill at Windjana, engineers have asked the rover to perform a number of tasks, including observations with the camera and X-ray spectrometer located at the end of the its arm and interpretations of composition at different points on the rock with a device that fires laser shots from the rover's mast."

By time it was four minutes old, it was 92% hydrogen (by number of atoms) and 8% helium. Yet the Universe has aged nearly 14 billion years since then, and have formed many generations of stars, all of which burn hydrogen into heavier elements. So how much hydrogen is left, and how much will be left far into the future? A lot more than you might think."

Frigid Brown Dwarf Found Only 7.2 Light-Years Away 142

An anonymous reader writes "Astronomer Kevin Luhman just found the 7th closest star to the sun. It's a mere 7.2 light-years away, discovered using NASA's Spitzer and WISE telescopes. How could it exist so close for so long without us knowing? It's a brown dwarf — barely a star at all. 'Brown dwarfs are star-like objects that are more massive than planets, but not quite massive enough to ignite sustained fusion in their cores. Hydrogen fusion is what powers the Sun, and makes it hot; it's the mighty pressure of the Sun's core that makes that happen. Brown dwarfs don't have the oomph needed to keep that going.' This small almost-star is downright chilly at around 225-260 Kelvin. That's -48 to -13 C (or -54 to 9 F). As Phil Plait points out, that's not much different from the temperature in the freezer in your kitchen. He adds, 'It implies this object is very old, too, because it would've been a few thousands degrees when it formed, and would take at least a billion years to cool down to its current chilly temperature. It's hard to determine how old it actually is, but it's most likely 1-10 billion years old. It has a very low mass, too, probably between 3 and 10 times the mass of Jupiter. That's pretty lightweight even for a brown dwarf. And here's another amazing thing about it: It might be a planet. What I mean is, it may have formed around a star like a planet does, then got ejected by gravitational interactions with other planets.'"

Making Graphene Work For Real-World Devices 18

Posted by Soulskill
from the more-better-faster-lighter-cheaper dept.
aarondubrow writes: "Graphene, a one-atom-thick form of the carbon material graphite, is strong, light, nearly transparent and an excellent conductor of electricity and heat, but a number of practical challenges must be overcome before it can emerge as a replacement for silicon in electronics or energy devices. One particular challenge concerns the question of how graphene diffuses heat, in the form of phonons. Thermal conductivity is critical in electronics, especially as components shrink to the nanoscale. Using the Stampede supercomputer at the Texas Advanced Computing Center, Professor Li Shi simulated how phonons (heat-carrying vibrations in solids) scatter as a function of the thickness of the graphene layers. He also investigated how graphene interacts with substrate materials and how phonon scattering can be controlled. The results were published in the Proceedings of the National Academy of Sciences, Applied Physical Letters and Energy and Environmental Science."

Fossils of Earliest Known Pterosaur Found 18

damn_registrars writes: "A fossil of the earliest known Pterosaur flying reptile was found recently in China. Named Kryptodrakon progenitor, it was described in a paper published yesterday in the journal Current Biology (abstract). Its wingspan was about a meter and a half, very small compared to its evolutionary descendents, whose wingspan reached over 10 meters. 'The pterosaurs remained largely unchanged for tens of millions of years — with characteristics like long tails and relatively small heads — and none became very big. But later during the Jurassic period, some developed anatomical changes that heralded the arrival of a new branch called pterodactyloids that eventually replaced the more primitive forms of pterosaurs. Many of these pterodactyloids had massive, elongated heads topped with huge crests, lost their teeth and grew to huge sizes. Perhaps the defining characteristic of the group is an elongation in the bone at the base of the fourth finger called the fourth metacarpal, and Kryptodrakon is the oldest known pterosaur to have this advance, the researchers said.'"

That's what speed-reading apps claim, promising to boost not just the number of words you read per minute, but also how well you understand a text. There's just one problem: The same thing that speeds up reading actually gets in the way of comprehension, according to a new study (abstract). Apps like Spritz or the aptly-named Speed Read are built around the idea that these eye movements, called saccades, are a redundant waste of time. It's more efficient, their designers claim, to present words one at a time in a fixed spot on a screen, discouraging saccades and helping you get through a text more quickly. But that's not what researchers have found."

Algorithm Distinguishes Memes From Ordinary Information 38

Posted by Soulskill
from the i-wonder-what-scumbag-d&d-player-thinks dept.
KentuckyFC writes: "Memes are the cultural equivalent of genes: units that transfer ideas or practices from one human to another by means of imitation. In recent years, network scientists have become increasingly interested in how memes spread, work that has led to important insights into the nature of news cycles, into information avalanches on social networks and so on. But what exactly makes a meme and distinguishes it from other forms of information is not well understood. Now a team of researchers has developed a way to automatically distinguish scientific memes from other forms of information for the first time. Their technique exploits the way scientific papers reference older papers on related topics. They scoured the half a million papers published by Physical Review between 1893 and 2010 looking for common words or phrases. They define an interesting meme as one that is more likely to appear in a paper that cites another paper in which the same meme occurs. In other words, interesting memes are more likely to replicate. They end up with a list of words and phrases that have spread by replication and can also see how this spreading has changed over the last 100 years. The top five phrases are: loop quantum cosmology, unparticle, sonoluminescence, MgB2 and stochastic resonance; all of which are important topics in physics. The team say the technique is interesting because it provides a way to distinguish memes from other forms of information that do not spread in the same way through replication."

SpaceX Files Suit Against US Air Force 176

Posted by Soulskill
from the go-big-or-go-home dept.
Today Elon Musk announced that SpaceX has decided to challenge the U.S. Air Force's restrictions on rocket launches related to national security. Such launches are done with a Russian rocket right now, and that contract is not up for competition with other rocket makers, like SpaceX. Musk says the company has exhausted other options to become part of the bidding process. "We're just protesting and saying these launches should be competed. And if we compete and lose, that's fine, but why were they not even competed?" He also said it's the "wrong time to send hundreds of millions of dollars to the Kremlin," referencing events in the Ukraine.

At the same press conference, Musk announced that SpaceX's recent attempt to soft-land a rocket booster stage was successful. It landed and was in "healthy condition" immediately afterward. Unfortunately, they weren't able to recover it because it landed in the middle of a rough storm, which eventually destroyed the stage. The storm was rough enough that the Coast Guard wouldn't even send a boat out to help recover it. Musk said, "We'll get much bigger boats next time." SpaceX also plans on landing the stage on shore at some point, which makes recovery easier. Musk made this prediction: "I expect we will be able to land a stage back at Cape Canaveral by the end of the year."

After gluing the two stretched strips together, the researchers gradually drained the water from the cup. As the bands retracted and twisted from the reduced strain, the researchers were shocked to see the formation of a hemihelix with multiple rainbow-shaped boundaries called perversions. The team hopes their work inspires nanodevices and molecules that twist and transform from flat strips into predetermined 3D shapes on demand."

Thanks to the technical savvy and DIY engineering of the team at LOIRP, it's being seen at a higher resolution than was ever previously possible. ... The photos were stored with remarkably high fidelity on the tapes, but at the time had to be copied from projection screens onto paper, sometimes at sizes so large that warehouses and even old churches were rented out to hang them up. The results were pretty grainy, but clear enough to identify landing sites and potential hazards. After the low-fi printing, the tapes were shoved into boxes and forgotten. ... The drives had to be rebuilt and in some cases completely re-engineered using instruction manuals or the advice of people who used to service them. The data they recovered then had to be demodulated and digitized, which added more layers of technical difficulties."

As for humanity's role in climate change, 33 percent accepted, 28 percent were unsure, and 37 percent fell in the doubter category. For a 4.5-billion-year-old Earth and a 13.8-billion-year-old Big Bang, acceptance was below 30 percent. Fully half of the public doubted the Big Bang (PDF).'"

Experiment Suggests Monkeys Can Do Basic Math 87

sciencehabit (1205606) writes "It looks like a standardized test question: Is the sum of two numbers on the left or the single number on the right larger? Rhesus macaques that have been trained to associate numerical values with symbols can get the answer right, even if they haven't passed a math class. The finding doesn't just reveal a hidden talent of the animals—it also helps show how the mammalian brain encodes the values of numbers. Previous research has shown that chimpanzees can add single-digit numbers. But scientists haven’t explained exactly how, in the human or the monkey brain, numbers are being represented or this addition is being carried out. Now, a new study (abstract) helps begin to answer those questions."

Lasrick (2629253) writes "Really interesting piece by Emma Rosenblum about women freezing their eggs in order to take 'biological clock' pressure off while they pursue careers: 'Not since the birth control pill has a medical technology had such potential to change family and career planning. The average age of women who freeze their eggs is about 37, down from 39 only two years ago... And fertility doctors report that more women in their early 30s are coming in for the procedure. Not only do younger women have healthier eggs, they also have more time before they have to use them.'"

Venus' Crust Heals Too Fast For Plate Tectonics 135

Posted by samzenpus
from the too-hot-to-crack dept.
An anonymous reader writes in with an interesting look at how important plate tectonics may be to life and why the crust on Venus works differently than it does on Earth. "Without plate tectonics, carbon would build up in the atmosphere. Venus, which does not have tectonics, shows the results: an atmosphere that is 96 percent carbon dioxide. It's toxic. Yet Venus is about the same size and composition as our planet, so why doesn't it have plate tectonics? Some researchers made a model to explore how Earth initiated plate movements, and these same researchers made one model of its neighbor for comparison. A 1.5-billion-year-old Earth and a similarly aged Venus were modeled as a hot, mushy material made of tiny particles of rock. The model uses physics at the one-millimeter rock grain scale to explain how the whole planet behaves. According to David Bercovici, a geophysicist at Yale who was an author on the paper, the model also shows how plate tectonics emerged on Earth but not on her twin."

$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand 288

An anonymous reader writes "A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' an open source hand which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."

New submitter Chipmunk100 (3619141) writes "Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions."

Why Portland Should Have Kept Its Water, Urine and All 332

Posted by timothy
from the except-for-homeopathy dept.
Ars Technica has nothing good to say about the scientific understanding (or at least public understanding) that led Portland to drain 38 million gallons of water after a teenage prankster urinated into the city's water supply. Maybe SCADA systems shouldn't be quite as high on the list of dangers, when major utilities can be quite this brittle even without a high-skill attack.

SpaceX Successfully Delivers Supplies To ISS 87

from the eggs-and-dye-mostly dept.
Reuters reports on the successful SpaceX-carried resupply mission to the ISS: "A cargo ship owned by Space Exploration Technologies arrived at the International Space Station on Sunday, with a delivery of supplies and science experiments for the crew and a pair of legs for the experimental humanoid robot aboard that one day may be used in a spacewalk. Station commander Koichi Wakata used the outpost's 58-foot (18-meter) robotic crane to snare the Dragon capsule from orbit at 7:14 a.m. (1114 GMT), ending its 36-hour journey. ... "The Easter Dragon is knocking at the door," astronaut Randy Bresnik radioed to the crew from Mission Control in Houston. Space Exploration, known as SpaceX, had planned to launch its Dragon cargo ship in March, but was delayed by technical problems, including a two-week hold to replace a damaged U.S. Air Force radar tracking system."

LADEE Probe Ends Its Mission On the Far Side Of the Moon 25

Posted by timothy
from the in-lieu-of-flowers dept.
The mission of NASA's LADEE probe was brought to an intentional violent end yesterday, when it smashed into the far side of the moon. As the Ars Technica report explains, "NASA's policy is to treat the locations of the Moon landings as historical sites, and it takes pains to preserve them from possible damage. LADEE didn't have the fuel to control its orbit indefinitely. As a result, the controllers had been preparing to terminate the probe for several weeks. ... The exact moment of impact isn't clear, since the precise terrain it hit couldn't be determined in advance. (If it hit a ridge, it would have happened earlier than if LADEE plowed across a plain. What is clear is that the impact destroyed the probe." Before the end of LADEE's mission, besides close up observations, the craft was used to test a new laser-based communication system.

RIP, NASA Moon Landing Engineer John C. Houbolt 33

from the why-when-he-was-a-boy dept.
The Houston Chronicle reports the death of John C. Houbolt, whose ideas helped guide the U.S. moon-landing programs. Houbolt died on Tuesday at the age of 95, in a nursing home in Maine. Says the Chronicle's obituary: "His efforts in the early 1960s are largely credited with convincing NASA to focus on the launch of a module carrying a crew from lunar orbit, rather than a rocket from earth or a space craft while orbiting the planet. Houbolt argued that a lunar orbit rendezvous, or lor, would not only be less mechanically and financially onerous than building a huge rocket to take man to the moon or launching a craft while orbiting the earth, but lor was the only option to meet President John F. Kennedy's challenge before the end of the decade."

Closing Surgical Incisions With a Paintbrush and Nanoparticles 56

Posted by timothy
from the when-superglue-just-feels-cheap dept.
New submitter BiancaM (3582365) writes "A group of chemists has shown the power of nanoparticles for closing and healing surgical wounds. Using no more than a paintbrush they are able to close surgical openings as well as classical techniques such as sutures. However in fragile deep tissues such as liver even more remarkable results were found- normally fatal damage to internal organs is repaired in seconds using a nanoparticle glue. The results show that closing after surgery can be faster and simpler using nanomaterials to glue wounds shut." For something between the above linked abstract and the research paper, there's this write-up at PhysOrg, and a video of the technique in action.

Preventative Treatment For Heartbleed On Healthcare.gov 81

As the San Francisco Chronicle reports, "People who have accounts on the enrollment website for President Barack Obama's signature health care law are being told to change their passwords following an administration-wide review of the government's vulnerability to the confounding Heartbleed Internet security flaw." Take note, though; the article goes on to immediately point out this does not mean that the HealthCare.gov site has been compromised: "Senior administration officials said there is no indication that the HealthCare.gov site has been compromised and the action is being taken out of an abundance of caution. The government's Heartbleed review is ongoing, the officials said, and users of other websites may also be told to change their passwords in the coming days, including those with accounts on the popular WhiteHouse.gov petitions page."

3 Former Astronauts: Earth-Asteroid Collisions Are a Real But Preventable Danger 71

Posted by timothy
from the asteroid-survival-movies-are-great dept.
Three former astronauts — Ed Lu, Tom Jones, and Bill Anders — say that reassuring figures about the rarity of asteroid collisions with Earth are perhaps too reassuring. The B612 Foundation, of which Lu is a director, has been established to draw public awareness to the risks of a large asteroid hitting a population center -- which these three men say is a far more serious public danger than has been acknowledged by NASA and other agencies. And beyond awareness, the Foundation's immediate goal is to raise money to " design and build an asteroid-finding space telescope and launch it by 2017," and then, Armageddon-style, to follow that up with technology to divert any asteroids whose path would threaten earth.
