New submitter kelk1 writes "If the size and mass of this gas halo is confirmed, it also could be an explanation for what is known as the 'missing baryon' problem for the galaxy [...] a census of the baryons present in stars and gas in our galaxy and nearby galaxies shows at least half the baryons are unaccounted for [...] Although there are uncertainties, the work by Gupta and colleagues provides the best evidence yet that the galaxy's missing baryons have been hiding in a halo of million-kelvin gas that envelopes the galaxy."
RocketAcademy writes "The Romney-Ryan campaign has released a white paper on space policy, which observers find to be long on criticisms of the Obama Administration but short on specific recommendations. The policy promises 'a robust role for commercial space,' but it's clearly a supporting role: 'NASA will set the goals and lead the way in human space exploration.' When it comes to space, both parties put government ahead of private enterprise. Some see a parallel with the policies which are driving space companies out of California. Newt Gingrich, one of the few politicians who thinks seriously about space, says the policy is a step in the right direction but not enough."
quax writes "In the wake of the Fukushima disaster the nuclear industry again faces massive opposition. Germany even decided to abandon nuclear energy altogether and the future of the industry is under a cloud of uncertainty in Japan. But one thing seems to be here to stay for a very, very long time: radioactive waste that has half-lives measured in thousands of years. But there is a technology under development in Belgium that could change all this: A sub-critical reactor design, driven by a particle accelerator can transmute the nuclear waste into something that goes away in about two hundred years. Could this lead to a revival of the nuclear industry and the reprocessing of spent reactor fuel?"
ericjones12398 writes "Every year, around 250,000 women die due to complications from pregnancy and childbirth. New research developing cheap, portable ultrasounds could help reduce that number. From the article: 'Although diagnostic imaging is scarce in much of the developing world (mostly related to cost and portability), ultrasound imaging is a feasible technology for prototyping in low-resource settings such as developing countries. Indeed, many notable technology giants, such as GE and Siemens, are working on low-cost portable ultrasound models. GE’s Vscan is a handheld, pocket-sized visualization tool that allows for non-invasive ultrasounds. Mobisante, a startup in Seattle, takes portable ultrasound technology one step further with the MobiUS SP1 system, an ultrasound that wirelessly connects to the Internet or a smartphone for viewing results at an affordable price tag. By comparison, the large, clunky ultrasound machine most people associate with hospitals can cost anywhere from $32,000-$160,000.'"
PolygamousRanchKid writes "As the worst drought in half a century has ravaged this year's U.S. corn crop and driven corn prices sky high, the market for alternative feed rations for beef and dairy cows has also skyrocketed. Brokers are gathering up discarded food products and putting them out for the highest bid to feed lot operators and dairy producers, who are scrambling to keep their animals fed. In the mix are cookies, gummy worms, marshmallows, fruit loops, orange peels, even dried cranberries. Cattlemen are feeding virtually anything they can get their hands on that will replace the starchy sugar content traditionally delivered to the animals through corn. Operators must be careful to follow detailed nutritional analyses for their animals to make sure they are getting a healthy mix of nutrients, animal nutritionists caution. But ruminant animals such as cattle can safely ingest a wide variety of feedstuffs that chickens and hogs can't. The candy and cookies are only a small part of a broad mix of alternative feed offerings for cattle. Many operators use distillers grains, a byproduct that comes from the manufacture of ethanol."
szyzyg writes "I've created some popular science videos showing how asteroid discoveries have happened over the last few decades. However I've run into a problem with a religious organization which borrowed my video and redubbed it to promote their religious message. Ultimately I filed a DMCA takedown request via YouTube's site, it's as easy as filling in a form and the video was removed. But this organization has since submitted a counterclaim claiming 'under penalty of perjury' that they do in fact have the rights to this work, and YouTube has reinstated the video. It looks like the only way I can pursue this further is to spend the money to take the organization to court and get an injunction, but even if I did so I'd have to pay court costs up front and since they're based in another country I'd have a difficult time actually collecting any money from the other party. It feels like this other group is simply gambling that I won't spend the time and resources to take further legal action, the DMCA is supposed to provide equal protection but the more lawyer you have the more 'equal' you are. So does anyone have any suggestions for how I should proceed here?"
Hugh Pickens writes "BBC reports that Tom Welton, a professor of sustainable chemistry at Imperial College, London, believes that a global shortage of helium means it should be used more carefully — and since helium cools the large magnets inside MRI scanners it is wrong to use it for balloons used at children's parties. 'We're not going to run out of helium tomorrow — but on the 30 to 50 year timescale we will have serious problems of having to shut things down if we don't do something in the meantime,' says Welton. 'When you see that we're literally just letting it float into the air, and then out into space inside those helium balloons, it's just hugely frustrating. It is absolutely the wrong use of helium.' Two years ago, the shortage of helium prompted American Nobel Prize winner Robert Richardson to speak out about the huge amounts of helium wasted every day because the gas is kept artificially cheap by the U.S. government and to call for a dramatic increase in helium's price. But John Lee, chairman of the UK's Balloon Association, insists that the helium its members put into balloons is not depriving the medical profession of the gas. 'The helium we use is not pure,' says Lee. 'It's recycled from the gas which is used in the medical industry, and mixed with air. We call it balloon gas rather than helium for that reason.'"
hessian writes with this news from the New York Times: "Since 2000, Dr. [Steven] Running and his colleagues have monitored how much plant growth covers terra firma, using two NASA satellites in the agency's Earth Observing System. After they crunched the numbers, combining the current monitoring system's data with satellite observations dating back to 1982, they noticed that terrestrial plant growth, also known as net primary production, remained relatively constant. Over the course of three decades, the observed plant growth on dry land has been about 53.6 petagrams of carbon each year, Dr. Running writes in the article. This suggests that plants' overall productivity — including the corn that humans grow and the trees people log for paper products — is changing little now, no matter how mankind tries to boost it, he said."
theodp writes "As part of the economic stimulus program, the Obama administration put into effect a Bush-era incentive program that provides tens of billions of dollars for physicians and hospitals that make the switch to electronic records, using systems like Athenahealth [note: video advertisement] (which made U.S. CTO Todd Park a wealthy man). The goal was not only to improve efficiency and patient safety, but also to reduce health care costs. But, in reality, the move to electronic health records may be contributing to billions of dollars in higher costs for Medicare, private insurers and patients by making it easier for hospitals and physicians to bill more for their services, whether or not they provide additional care. Hospitals received $1 billion more in Medicare reimbursements in 2010 than they did five years earlier, at least in part by changing the billing codes they assign to patients in emergency rooms, according to a NY Times analysis. There are also fears that features which can be used to automatically generate detailed patient histories and clone examination findings for multiple patients make it too easy to give the appearance that more thorough exams were conducted than perhaps were. Critics say the abuses are widespread. 'It's like doping and bicycling,' said Dr. Donald W. Simborg. 'Everybody knows it's going on.'"
shortyadamk writes "According to the Government Services Administration auction page: 'Attention GSA Auctions bidders and interested participants. NASA (National Aeronautics and Space Administration) Space Shuttle Program has retired and NASA has partnered with GSA Auctions to sell the many shuttle related items through a series of auctions in 2012.' The only catch is that you must be a U.S. Citizen and schedule a visit 48 hours ahead of time to pick up your item. I'm not really sure which piece of the shuttle I'd want the most... Those robotic arms are pretty sweet."
The Bad Astronomer writes "An extremely bright meteor burned up over Ireland and the northern UK around 22:00 UTC on Friday night, and was apparently witnessed by thousands of people. It traveled east to west, and was moving relatively slowly. It may have been an actual rock, or it may have been some human-made space debris — a satellite or rocket booster — burning up. Space junk tends to move more slowly, so that's a potential suspect, though orbiting debris usually moves in the opposite direction. I'm collecting pictures and images on my Bad Astronomy blog."
New submitter mybluevan writes "The Public Laboratory for Open Technology and Science is putting together an open hardware spectrometer kit on Kickstarter. The kits are built using an HD webcam, discarded DVD, and a couple other odd bits. They've also put together a kit for your smart phone and open-source software for desktop, Android, and iOS. Need to analyze the contents of your coffee, the output of your new grow lights, or a distant star on a budget? Just build your own spectrometer, or pick up the limited edition steampunk version." Besides making cool hardware, they'd like to "build a Wikipedia-style library of open source spectra, and to refine and improve sample collection and analysis techniques. We imagine a kind of 'SHAZAM for materials' which can help to investigate chemical spills, diagnose crop diseases, identify contaminants in household products, and even analyze olive oil, coffee, and homebrew beer."
Today the space shuttle Endeavor completed its final ferry flight, landing in Los Angeles, California after leaving Edwards Air Force Base earlier today. The shuttle will now undergo preparations for its journey through the streets of L.A. (at a cost of 400+ trees) to its final resting place at the California Science Center. It'll go on public display October 30. Endeavor spent over 296 days in space throughout 25 missions, comprising 4,671 orbits that added up to over 197 million kilometers of travel. Slashdot's own Kaushik Acharya was at the Griffith Observatory in L.A. for the flyover, and he provided some great pictures of Endeavor's passing.
scibri writes "Think the imprisonment of Pussy Riot is a miscarriage of justice? Check out the story of their cellmate: Chemist Olga Nikolaevna Zelenina heads a laboratory at the Penza Agricultural Institute. She is an expert in the biology of hemp and poppy, and is a sought-after expert in legal cases involving narcotics produced from these plants. Last year, she was asked by defense lawyers to give her opinion in a case involving imported poppy seeds. The prosecutors didn't like her evidence though, and now she's in prison accused of complicity in organized drug trafficking."
An anonymous reader writes "Early humans were able to move from Africa after a single genetic mutation allowed them to become vegetarians, scientists claim. The switch, which allowed humans to process vegetables, meant that humans were able to move away from water sources and spread across the continent. A team of geneticists compared DNA sequences from a variety of people around the world to see how different populations relate to one another and when they have gone their separate ways. The scientists found that a key genetic variant gave humans the ability to convert fats from plants into essential nutrients for the brain."
