Arvisp writes with the news of a recently discovered antifreeze molecule in an Alaskan beetle that departs from most commonly identified natural antifreeze. "'The most exciting part of this discovery is that this molecule is a whole new kind of antifreeze that may work in a different location of the cell and in a different way,' said zoophysiologist Brian Barnes, director of the University of Alaska Fairbanks Institute of Arctic Biology and one of five scientists who participated in the Alaska Upis ceramboides beetle project. Just as ice crystals form over ice cream left too long in a freezer, ice crystals in an insect or other organism can draw so much water out of the organism's cells that those cells die. Antifreeze molecules function to keep small ice crystals small or to prevent ice crystals from forming at all. They may help freeze-tolerant organisms survive by preventing freezing from penetrating into cells, a lethal condition. Other insects use these molecules to resist freezing by supercooling when they lower their body temperature below the freezing point without becoming solid."Read more of this storyat Slashdot.

  tresho writes to tell us that virtual doctors visits seem to be on the rise. A new service, most recently deployed in Texas, from "NowClinic" is allowing doctors to make virtual house calls and prescribe anything short of controlled substances. "For $45, anyone in Texas can use NowClinic, whether or not they are insured, by visiting NowClinic.com. Doctors hold 10-minute appointments and can file prescriptions, except for controlled substances. Eventually they will be able to view patients’ medical histories if they are available. The introduction of NowClinic will be the first time that online care has been available nationwide, regardless of insurance coverage."Read more of this storyat Slashdot.

  Wrath0fb0b writes "Oklahoma State University President Burns Hargis has abruptly canceled an NIH-funded study on an anthrax vaccine in primates. (The primates would have to be euthanized afterward.) There is suspicion that the decision was meant to appease large donor Madeleine Pickens, the wife of noted huntsman T. Boone Pickens, who had previously pressured the school over animal-rights issues. Scientists counter that the study was approved by the NIH peer-review process, the Institutional Animal Care and Use Committee (IACUC) and subject to the Federal Animal Welfare Act (by virtue of using NIH money) and that the decision by the President has short-circuited months of planning and deliberation on the matter. Hargis has denied being influenced by Pickens and cited 'confidential factors' that he couldn't discuss, telling the faculty council that 'to go through every lurid detail is simply not prudent.' A post on Pickens' blog, on the other hand, obliquely takes credit for the 'great decision,' noting a faculty member's hunch that the 'generous benefactor to OSU and her ties to the Humane Society of the United States may have played a role in the termination of the project.' Meanwhile, the NIH expressed displeasure at the decision, stating, 'NIH fully expects institutions to honor these assurances and commitment to complete NIH supported projects as requested, approved and funded.' Some OSU scientists speculated that the fiasco would make it harder for them to receive NIH funding in the future."Read more of this storyat Slashdot.

  c0mpliant writes "NASA and the Jet Propulsion Laboratory have released a simulation of the path of an asteroid, named Apophis, that will come very close to Earth in 2029 — the closest predicted approach since humans have monitored for such heavenly bodies. The asteroid caused a bit of a scare when astronomers first announced that it would enter Earth's neighborhood some time in the future. However, since that announcement in 2004, more recent calculations have put the odds of collision at 1 in 250,000."Read more of this storyat Slashdot.

  Hugh Pickens writes "The Himalayas, home to some 10,000 glaciers, are the main source of replenishment to lakes, streams, and some of the continent's mightiest rivers, on which millions of people depend for their water supplies. Since the 1960s, the acreage covered by Himalayan glaciers has declined by more than 20 percent with a rate of warming twice the global average over the past 30 years. Now Live Science reports that tiny particles of pollution known as 'black carbon' — and not heat-trapping greenhouse gases — may be causing much of the rapid melting of glaciers in the Himalayas. 'Tibet's glaciers are retreating at an alarming rate,' says James Hansen, director of NASA's Goddard Institute for Space Studies in New York City. 'Black soot is probably responsible for as much as half of the glacial melt, and greenhouse gases are responsible for the rest.' The circulation of the atmosphere in the region causes much of the soot-laden air to 'pile up' against the Himalayas. The soot mixes with other dust from nearby deserts, creating a massive brown cloud visible from space that absorbs incoming solar radiation. As this layer heats up in the Himalayan foothills, it rises and enhances the seasonal northward flow of humid monsoon winds, forcing moisture and hot air up the slopes of the mountain range."Read more of this storyat Slashdot.

  EagleHasLanded writes "Russian mathematician Grigory Perelman doesn't talk to journalists. Actually, he doesn't talk to anyone anymore. So we'll have to settle for insights via his biographer, Masha Gessen, who, strangely enough, has never talked to him either. But she has spoken with just about everyone who has ever had any significant interaction with Perelman, and the result is the book Perfect Rigor, which more than adequately explains why Perelman has gone into self-imposed exile, and why he probably won't collect the million dollars he won by solving the Poincare Conjecture."Read more of this storyat Slashdot.

  The BBC has a report on a proposal that will be submitted to NASA for funding — a mission to Saturn's moon Titan that would deposit a lander on its hydrocarbon sea. (We recently discussed the widely-circulated photo of sunlight glinting off one of Titan's seas.) "The scientific team behind the idea is targeting Ligeia Mare, a vast body of liquid methane sited in the high north of Saturn's largest moon. ... 'It is something that would really capture the imagination,' said Dr Ellen Stofan, from Proxemy Research, who leads the study team. 'The story of human exploration on Earth has been one of navigation and seafaring, and the idea that we could explore for the first time an extraterrestrial sea I think would be mind-blowing for most people,' she told BBC News. ... The Titan Mare Explorer (TiME) has already been under study for about two years. It is envisaged as a relatively low-cost endeavor — in the low $400m range. It could launch in January 2016, and make some flybys of Earth and Jupiter to pick up the gravitational energy it would need to head straight at the Saturnian moon for a splash down in June 2023."Read more of this storyat Slashdot.

  elyons writes "Another neat discovery has come from the lab of Larry Lyons at UCLA. As reported earlier on Slashdot, Lyons' group studies the dynamics of auroras. Their most recent discovery reveals for the first time the sequence of events leading to dramatic space-weather disturbances. Using a network of cameras deployed around the Arctic in support of NASA's THEMIS mission, they recorded over 200 instances of auroras colliding, causing brilliant displays of northern lights (see time 8:22 for such an example)."Read more of this storyat Slashdot.

  Hugh Pickens writes "Nature reports that data collected on the timing of attacks and number of casualties from more than 54,000 events across nine insurgent wars, including those fought in Iraq between 2003 and 2008 and in Sierra Leone between 1994 and 2003, suggest that insurgencies have a common underlying pattern that may allow the timing of attacks and the number of casualties to be predicted. By plotting the distribution of the frequency and size of events, the team found that insurgent wars follow an approximate power law, in which the frequency of attacks decreases with increasing attack size to the power of 2.5. This means that for any insurgent war, an attack with 10 casualties is 316 times more likely to occur than one with 100 casualties (316 is 10 to the power of 2.5). 'We found that the way in which humans do insurgent wars — that is, the number of casualties and the timing of events — is universal,' says team leader Neil Johnson, a physicist at the University of Miami in Florida. 'This changes the way we think insurgency works.' To explain what was driving this common pattern, the researchers created a mathematical model which assumes that insurgent groups form and fragment when they sense danger, and strike in well-timed bursts to maximize their media exposure. Johnson is now working to predict how the insurgency in Afghanistan might respond to the influx of foreign troops recently announced by US President Barack Obama. 'We do observe a complicated pattern that has to do with the way humans do violence in some collective way,' adds Johnson."Read more of this storyat Slashdot.

NASA would receive an additional $1 billion in 2011 bothto get the new launcher on track and to bolster the agency's fleet of robotic Earth-monitoring spacecraft."Read more of this storyat Slashdot.

  During two seminars at Stanford and Fermilab on Thursday, researchers described signals for two events detected deep in an old iron mine in Minnesota that might mark the first detection of dark matter — or not. The presenters said the chances that the signals they detected were caused by something other than "neutralino" dark matter particles was 23 percent. "One source indicates that we'd need less than 10 total detections within the CDMS' range in order to have a high degree of confidence in the results." The NY Times describes the Cryogenic Dark Matter Search methodology: "The cryogenic experiment is nearly half a mile underground in an old iron mine in Soudan, Minn., to shield it from cosmic rays. It consists of a stack of germanium and silicon detectors, cooled to one-hundredth of a degree Kelvin. When a particle hits one of the detectors, it produces an electrical charge and deposits a small bit of energy in the form of heat, each of which are independently measured. By comparing the amounts of charge and heat left behind, the collaboration’s physicists can tell so-called wimps from more mundane particles like neutrons, which are expected to flood the underground chamber from radioactivity in the rocks around it." Here are the research team's summary notes of the latest results (PDF).Read more of this storyat Slashdot.

  mantis2009 writes "When it comes to stopping a cataclysmic Earth vs. asteroid event, social science and international political leaders have more difficult questions yet unanswered than physicists do, according to report delivered at this week's American Geophysical Union meeting. Wired has a discussion of an analysis authored by former astronaut Rusty Schweickart, who worries that the international community is nowhere near ready to begin the complex and inevitably controversial task of deflecting an asteroid on a collision course with Earth. Among the questions to be answered is whether to modify the Partial Test Ban Treaty to allow nuclear weapons in outer space. Another possibility to avoid the destruction of civilization would require the international community to choose an area on the globe where an asteroid might be 'aimed.' Who would decide which nations get placed in the asteroid's crosshairs?"Read more of this storyat Slashdot.
