A story at Slashgear says that the remains of a Soviet mission to Mars may have been spotted — on Mars — by enthusiasts poring over old photos taken by a NASA orbiter. The article points out that the find must be confirmed by further imaging, but matches the seekers' expectations. From the article: "The community at VK.com/Curiosity_Live crowdsourced a mission to find the Soviet Union’s long-lost Mars 3 spacecraft, with the site’s leader, Vitali Egorov of St. Petersburg, Russia, creating models of what hardware from the spacecraft should look like. With this reference, the community combed through a large image taken five years ago by NASA’s MRO, identifying what is believed to be the craft’s parachute, lander, terminal retrorocket, and heat shield."

ananyo writes "Francis Crick's Nobel medal fetched US$2.27 million at an auction in New York yesterday. The proud new owner is Jack Wang, chief executive of 'Biomobie' a company that intends to sell walnut-sized, flying-saucer-shaped electromagnetic devices that it claims have medically regenerative powers. The closely-watched sale featured a range of Crick memorabilia that the family had kept in storage for many years. Up for auction along with the medal — awarded for Crick's role in the 1953 discovery of the structure of DNA — were his lab coat, sailing logbooks and garden journals. Expectations were high because the day before, auctioneer Christie's had brokered the sale of a letter from Crick (PDF) to his 12-year-old son for $6 million, more than triple the pre-sale estimate. The letter went to an anonymous bidder. The new owner of the Crick medal is a Chinese-born American who says his motivation for purchasing the medal was to stimulate research into the 'mystery of Bioboosti,' which, he says, produces electromagnetic stimulation that can 'control and enable the regeneration of damaged organs.' Those benefits are, needless to say, so far unproven. Crick's family has said it will donate at least 20% of the proceeds from the sale of the medal and other items to the Francis Crick Institute, a biomedical research centre scheduled to open in London in 2015."

astroengine writes "The International Astronomical Union (IAU) — the official body that governs the designations of all celestial bodies — in their capacity of purveyors of all things 'official' has deemed attempts at crowdsourcing names for exoplanets illegitimate. 'In the light of recent events, where the possibility of buying the rights to name exoplanets has been advertised, the International Astronomical Union wishes to inform the public that such schemes have no bearing on the official naming process,' writes Thierry Montmerle, General Secretary of the IAU in Paris, France. Although the 'schemes' are not specifically named, the most popular U.S.-based "exoplanet naming" group Uwingu appears to be the target of today's IAU statement. Set up by Alan Stern, planetary scientist and principal investigator for NASA's Pluto New Horizons mission, Uwingu encourages the public to nominate and vote (for a fee) on names for the slew of exoplanets steadily being discovered."

gbrumfiel writes "A strange green meteorite found in Morocco caused a stir in the press earlier this month, when scientists reported that it might be the first chunk of Mercury ever found here on earth. But scientists who've been puzzling over the stone since then say the accumulating evidence may point in a different direction. The 4.56-billion-year-old rock might have come from the asteroid belt located between Mars and Jupiter. If true, then it would provide clues about the origin of the solar system as a whole instead of the origin of the innermost planet."

ananyo writes "Toxic chemicals are accumulating in the ecosystems of the Himalayas and the Tibetan plateau, researchers warn in the first comprehensive study to assess levels of organic pollutants in that part of the world. Persistent organic pollutants (POPs) are carbon-based compounds that are resistant to break-down. Some originate from the burning of fuel or the processing of electronic waste, and others are widely used as pesticides or herbicides or in the manufacture of solvents, plastics and pharmaceuticals. Some POPs, such as the pesticide dichlorodiphenyltrichloroethane (DDT) and the herbicide Agent Orange, can cause diseases such as cancers, neurological disorders, reproductive dysfunction and birth defects. The researchers found large amounts of POPs (including DDT) in various components of the ecosystems such as soil, grass, trees and fish in the Himalayas and in the Tibetan plateau, especially at the highest elevations."

An anonymous reader sends news that Russian President Vladimir Putin unveiled today a new $50 billion effort to maintain and extend the country's space capabilities. Part of this initiative is a new spaceport located in Russia, which will lead to the first manned launches from Russian soil in 2018. Manned launches currently originate from the Baikonur Cosmodrome in Kazakhstan. "The Russian space programme has been hurt in recent years by a string of launch failures of unmanned probes and satellites, but Putin vowed Moscow would continue to ramp up spending. He said that from 2013-2020, Russia would be spending 1.6 trillion rubles ($51.8 billion, 38 million euros) on its space sector, a growth far greater than any other space power. 'Developing our potential in space will be one of the priorities of state policy,' Putin said at a meeting in the regional capital Blagoveshchensk. ... speaking to Canadian spaceman Chris Hadfield, currently commander of the ISS, Putin hailed cooperation in space which meant world powers could forget about the problems of international relations and think 'about the future of mankind.'"

anderzole writes "The FDA recently gave clearance to Vital Art and Science Inc. (VAS) to market software which enables people with degenerative eye conditions such as macular degeneration and diabetic retinopathy to monitor their vision at home with their iPhone. The software, which is called myVisionTrack, isn't a replacement for regular visits to the doctor, but rather allows patients to keep tabs on their vision in between visits with eye care professionals. VAS notes that retinal diseases affect approximately 40 million individuals worldwide and 13 million in the United States. While treatments have been developed to deal with degenerative eye conditions, early diagnosis is of paramount importance — which is why the software is so important."

ananyo writes "When U.S. presidential candidate Mitt Romney said last year that he was not even going to try to reach 47% of the US electorate, and that he would focus on the 5–10% thought to be floating voters, he was articulating a commonly held opinion: that most voters are locked in to their ideological party loyalty. But Lars Hall, a cognitive scientist at Lund University in Sweden, knew better. When Hall and his colleagues tested the rigidity of people's political attitudes and voting intentions during Sweden's 2010 general election, they discovered that loyalty was malleable: nearly half of all voters were open to changing their minds. Hall's group polled 162 voters during the final weeks of the election campaign, asking them which of two opposing political coalitions — conservative or social democrat/green — they intended to vote for. The researchers also asked voters to rate where they stood on 12 key political issues, including tax rates and nuclear power. The person conducting the experiment secretly filled in an identical survey with the reverse of the voter's answers, and used sleight-of-hand to exchange the answer sheets, placing the voter in the opposite political camp. The researcher invited the voter to give reasons for their manipulated opinions, then summarized their score to give a probable political affiliation and asked again who they intended to vote for. On the basis of the manipulated score, 10% of the subjects switched their voting intentions, from right to left wing or vice versa. Another 19% changed from firm support of their preferred coalition to undecided. A further 18% had been undecided before the survey, indicating that as many as 47% of the electorate were open to changing their minds, in sharp contrast to the 10% of voters identified as undecided in Swedish polls at the time (research paper). Hall has used a similar sleight of hand before to show that our moral compass can often be easily reversed."

coondoggie writes "There has been much chatter about the threat of an asteroid or significant meteor strike on Earth — mostly caused by the untracked meteor that blasted its way to international attention when it exploded in the sky above Russia injuring nearly 1,200 people in February. It was one of those amazing coincidences that on that same day an asteroid NASA had been tracking for months — asteroid 2012 DA14 — was to harmlessly cross Earth's path. Those events and the topic of mitigating asteroid and meteor or Near Earth Object threats to Earth prompted a couple congressional hearings by the Committee on Science, Space, and Technology, the latest of which was held this week. None of the NEOs found to date have more than a tiny chance of hitting Earth in the next century. Thus the near-term risk of an unwarned impact from large asteroids, and hence the majority of the risk from all NEOs, has been reduced by more than 90%. Assuming none are found to be an impact threat, discovering 90% of the 140 meter sized objects will further reduce the total risk to the 99% level. By finding these objects early enough and tracking their motions over the next 100 years, even those rare objects that might be found threatening could be deflected using existing technologies."

sciencehabit writes "Researchers have developed a camera system that shoots untouched flakes 'in the wild' as they fall from the sky. By grabbing a series of images of the tumbling crystals—its exposure time is one-40,000th of a second, compared with about one-200th in normal photography—the camera is revealing the true shape diversity of snowflakes. Besides providing beautiful real-time 3D snowflake photographs from a ski resort in Utah, the goal is to improve weather modeling. More accurate data on how fast snowflakes fall and how their shapes interacts with radar will improve predictions of when and where storms will dump snow and how much."

sciencehabit writes "Europe's best-known mummy wasn't just a medical mess; he also had terrible teeth, according to a new study. Ötzi, a Stone Age man who died atop a glacier about 5300 years ago, suffered from severe gum disease and cavities. When Ötzi was discovered atop a glacier on the Austro-Italian border, his frozen corpse was intensively studied. But no one took a close look at his teeth until now. Using 3D computer tomography (a CAT scan), the hunter's mouth could be examined for clues as to the life he led. A fall or other accident killed one of his front teeth, still discolored millennia later. And he may have had a small stone, gone unnoticed in his whole-grain bread or gruel, to thank for a broken molar. That gruel may be the culprit behind Ötzi's cavities and gum disease, too. The uptick in starches, the researchers suggest, could explain the increasing frequency of cavities in teeth from the time—a problem that's been with us ever since."

Now, fossilized embryos reveal that they were also the fastest growing animals on record — 'faster than anything we have ever seen,' according to one researcher. What's more, researchers have found traces of organic matter in their bones, which may belong to the oldest fossil proteins ever found."

First time accepted submitter jds91md writes "Scientists at Stanford have developed a technique to see the structural detail of actual brains with resolution down to the cellular and axonal/dendritic level. The process called CLARITY allows a 'transparent' view of the brain without having to slice or section it in any way. From the article: 'Even more important, experts say, is that unlike earlier methods for making the tissue of brains and other organs transparent, the new process, called Clarity by its inventors, preserves the biochemistry of the brain so well that researchers can test it over and over again with chemicals that highlight specific structures within a brain and provide clues to its past activity. The researchers say this process may help uncover the physical underpinnings of devastating mental disorders like schizophrenia, autism, post-traumatic stress disorder and others.'"

coondoggie writes "In the 1966 science fiction classic Fantastic Voyage, a tiny submarine with a crew of five is miniaturized and injected into a comatose man to surgically laser a blood clot in his brain and save his life. At this week's American Chemical Society Nanoengineering expert Joseph Wang detailed his latest work in developing micromotors and microrockets that are so small that thousands would fit inside this 'o'. Such machines could someday perform microsurgery, clean clogged arteries or transport drugs to the right place in the body. But there are also possible uses in cleaning up oil spills, monitoring industrial processes and in national security."

astroengine writes "Saturn's rings rain charged water particles down onto the gas giant's atmosphere, causing measurable changes in the planet's ionosphere. This intriguing conclusion comes from astronomers using the W. M. Keck Observatory atop Mauna Kea in Hawaii that observed dark bands forming in Saturn's ionosphere. 'Saturn is the first planet to show significant interaction between its atmosphere and ring system,' said James O'Donoghue, postgraduate researcher at the University of Leicester and lead author of a paper to appear this week in the journal Nature. 'The main effect of ring rain is that it acts to 'quench' the ionosphere of Saturn, severely reducing the electron densities in regions in which it falls.'"

New kalalau_kane writes with this tidbit from Extreme Tech: "A group of European researchers has proposed the largest quantum network yet: Between Earth and the International Space Station. Such a network would see entangled photons transmitted over a distance of 250 miles — two or three times greater than previous quantum communication experiments. Not only will this be the first quantum experiment in space, but it will allow the scientists to see if entanglement really is instantaneous over long distances, and whether it's affected by gravity."

sciencehabit writes "Get used to a bumpy ride. The strength and frequency of atmospheric turbulence affecting transatlantic flights will increase by midcentury, a new study suggests. During winter months, 16 of the 21 often-used ways in which scientists measure turbulence suggest that the average intensity of the plane-rattling phenomenon will be between 10% and 40% stronger when CO2 concentrations are double their preindustrial value. Accordingly, the frequency of moderate-or-greater turbulence—intensities at which passengers will experience accelerations of 0.5 g or more, which are strong enough to toss items about the cabin—will rise by between 40% and 170%. As a result of pilots needing to dodge strong turbulence, flight paths will become longer, and fuel consumption and carbon dioxide emissions will increase—possibly leading to even more turbulence."

mbstone writes "Lightning researcher Joseph Dwyer of the Florida Institute of Technology claims that thunderstorms unleash sprays of X-rays and even intense bursts of gamma rays which could cause airline passengers to receive in an instant the maximum safe lifetime dose of ionizing radiation — the kind that wreaks the most havoc on the human body. Dwyer hopes his sensor aboard the Fermi Gamma-ray Space Telescope, will provide more data."
