pigrabbitbear writes in with a link about a virtual reality helmet designed to help people deal with medical emergencies in space. "Humans are pretty fragile. A bad break in your hip can mean surgery and months of rehab. That's pretty bad, but what if you fall and break your hip on the Moon, or even Mars? You'd be hundreds of thousands or millions of miles from a fully stocked hospital and a surgeon with steady hands. There's the option of doctor-assisted surgery from Earth — a fellow astronaut performing the surgery with remote assistance from a doctor via video link. But the lengthy communications delay make this a poor option anywhere further than the Moon. Luckily for our Mars-bound descendants, the European Space Agency has a solution: an information-loaded assisted reality helmet that will let anyone identify and perform minor surgery to repair injuries."

MrSeb writes "Hold onto your hats: Scientists at the University of York, England have completely rewritten the rules of magnetic storage (abstract; full paper paywalled). Instead of switching a magnetic region using a magnetic field (like a hard drive head), the researchers have managed to switch a ferrimagnetic nanoisland using a 60-femtosecond laser. Storing magnetic data using lasers is up to 1,000 times faster than writing to a conventional hard drive (we're talking about gigabytes or terabytes per second) — and the ferrimagnetic nanoislands that store the data are capable of storage densities that are some 15 times greater than existing hard drive platters. Unfortunately the York scientists only detailed writing data with lasers; there's no word on how to read it."

New submitter garthsundem writes with this tale of digital love: "A newly published meta-analysis of over 400 studies of online dating (PDF) shows both its popularity (second only to meeting through friends) and its impact. More online daters report seeking a 'soulmate' online, and do so by searching through the wealth of available profiles. Unfortunately soul-searchers focus on faults, both in viewing profiles and then also once dating in person, leading to quick exits when relationships inevitably get complicated."

demachina writes "Robert Boisjoly has died at the age of 73. Boisjoly, Allan J. McDonald and three others argued through the night of 27 January, 1986 to stop the following day's Challenger launch, but Joseph Kilminster, their boss at Morton Thiokol, overruled them. NASA managers didn't listen to the engineers. Both Boisjoly and McDonald were blackballed for speaking out. NASA's mismanagement 'is not going to stop until somebody gets sent to hard rock hotel,' Boisjoly said after the 2003 Columbia disaster. 'I don't care how many commissions you have. These guys have a way of numbing their brains. They have destroyed $5 billion worth of hardware and 14 lives because of their nonsense.'"

ananyo writes "Today the two main experiments at the Large Hadron Collider, the world's most powerful particle accelerator, submitted the results of their latest analyses. The new papers (here here and here) boost the case for December's announcement of a possible Higgs signal. Physicists working on the In the case of the Compact Muon Solenoid experiment, have been able to look at another possible kind of Higgs decay, and that allows them to boost their Higgs signal from 2.5 sigma to 3.1 sigma. Taken together with data from the other detector, ATLAS, Higgs' overall signal now unofficially stands at about 4.3 sigma."

MrSeb writes "There are around 100 billion neurons in a human brain, forming up to 100 trillion synaptic interconnections. Neuroscientists believe that these synapses are the key to almost every one of your unique, identifiable features: Memories, mental disorders, and even your personality are encoded in the wiring of your brain. Understandably, neuroscientists really want to investigate these neurons and synapses to work out how they play such a vital role in our human makeup. Unfortunately, these 100 trillion connections are crammed into a two-pound bag of soggy flesh, making analysis rather hard. Starting small and working its way up, MIT today launched Eyewire, a crowdsourced 'game' that tasks users with wiring up the neurons in a mouse's retina. A future stage of the game will get users to find the synapses, too."

An anonymous reader writes "If we break a bone it can take weeks or even month to heal depending on the type and severity of the break. In some extreme cases the complexity of the fracture can make it impossible to heal properly. Researchers at the University of Georgia Regenerative Bioscience Center have come up with a new solution for healing broken bones that cuts recovery time to days. It relies on the use of stem cells that contain a bone generating protein. These cells are injected in gel form directly into the area of the broken bone, where they quickly get to work forming new bone. The end result is very rapid recovery, possibly sidestepping the muscle atrophy that can come with long bone healing times. The gel has been proven to work on animals as big as a sheep and has funding from the DoD. Lets hope it is proven to work on humans in the coming years."

astroengine writes "So it turns out U.S. radars weren't to blame for the unfortunate demise of Russia's Phobos-Grunt Mars sample return mission — it was a computer programming error that doomed the probe, a government board investigating the accident has determined." According to the Planetary Society Blog's unofficial translation and paraphrasing of the incident report, "The spacecraft computer failed when two of the chips in the electronics suffered radiation damage. (The Russians say that radiation damage is the most likely cause, but the spacecraft was still in low Earth orbit beneath the radiation belts.) Whatever triggered the chip failure, the ultimate cause was the use of non-space-qualified electronic components. When the chips failed, the on-board computer program crashed."

New submitter Morganth writes "According to New Scientist, researchers at DARPA are investing efforts in transcranial direct current stimulation (tDCS) machines to cut the time it takes to train snipers. From the article: 'a 2-milliamp current will run through the part of the brain associated with object recognition — an important skill when visually combing a scene for assailants.' The story also gives a nice explanation on the psychology of 'flow' — the state that experts tend to enter (e.g. programmers, tennis players, pianists) when focusing on their work." We covered similar research done on mice to improve their memory in September.

New submitter offsafely writes "Scientists in Australia have discovered the oldest living life-form to date: a small patch of Ancient Seagrass, dated through DNA sequencing at 200,000 years old." Says the linked article: "This is far older than the current known oldest species, a Tasmanian plant that is believed to be 43,000 years old." What I want to know is, How does it taste?

BuzzSkyline writes "Astronaut Don Pettit, who is aboard the International Space Station right now, puts charged water droplets into wild orbits around a knitting needle in the microgravity environment of the ISS. A video he made of the droplets is the first in a series of freefall physics experiments that he will be posting in coming months."

vikingpower writes "The Little Ice Age, lasting from the end of the Middle Age into the 17th century, may very likely have been caused by the combined effects of four major volcanic eruptions and increased sunlight reflection by increasing sea ice, the so-called Albedo effect. ... The University of Boulder has a press release with maps and photographs. Bette Otto-Bliesner, one of the scientists behind the 'volcano + sea ice' thesis, fields an earnest warning against drawing conclusions too quickly from this research: 'I think people might look at the Little Ice Age and think that all we need to save us from rising temperatures are some volcanic eruptions or the geo-engineering equivalent [...] But when you see what happened when global temperatures dropped by just one degree and you look at current predictions of six or seven degree increases for the future, you realize how precarious things are for life as we know it.'"

New submitter albinobee writes "The Kinect for Xbox 360 isn't only about gaming; it can also be used to help compensate for impaired vision, as a team of Indian engineers is working to prove. A device called viSparsh, still in its nascent stage, is a motion sensing belt that can help alert the blind to obstacles that lie in their path."

An anonymous reader writes "Scientists at the Universities of Southampton and Penn State have found a way to embed electronic components into optical fibers, in a breakthrough that could lead to the creation of super high-speed telecommunications networks. Rather than trying to merge flat chips with round optical fibers, the team of scientists used high-pressure chemistry techniques to deposit semiconducting materials layer by layer directly into tiny holes in optical fibers. This bypasses the need to integrate fiber-optics onto a chip, and means that the data signal never has to leave the fiber."

judgecorp writes "A research team at Manchester has taken a big step toward building transistors with graphene. So far graphene's marvelous conductivity has actually proved a drawback, but the team has sandwiched a layer of molybdenum disulfide between layers of graphene to provide a high on/off ratio. Also, the British Government is finding £50 million to fund Manchester as a center for graphene study and development, led by two professors there, Sir Kostya Novoselov and Sir Andre Geim, who shared the 2010 Nobel prize for Physics for their work on graphene."

astroengine writes "It's a strange irony that to afford the expense of space exploration, international collaboration is often sought after — spreading the cost across several international partners means the biggest space missions may be accomplished. And yet in times of austerity, national budgets balk at the prospect of investing in international projects like ExoMars. Sadly, that's exactly what could be facing the ambitious ESA-led Mars rover/satellite mission if NASA's Science Mission Directorate budget is slashed in the next financial year. NASA may pull out of the project, leaving ExoMars with no rockets or a means to actually land on Mars. Could Russia help out? Possibly, but it will still lead to ESA taking on more cost than it has budgeted for."

Zothecula writes "Research scientist Andreas Mershin has a dream to bring inexpensive solar power to the masses, especially those in developing countries. After years of research, he and his team at MIT's Center for Bits and Atoms, along with University of Tennessee biochemist Barry Bruce, have worked out a process that extracts functional photosynthetic molecules from common yard and agricultural waste. If all goes well, in a few years it should be possible to gather up a pile of grass clippings, mix it with a blend of cheap chemicals, paint it on your roof and begin producing electricity. Talk about redefining green power plants!"

First time accepted submitter tonique writes "Perl Data Language (PDL) 2.4.10 has been released. Highlights of the new release are automatic multi-thread support, support for data structures larger than 2 GB and POSIX threads support. Also available is the first draft of the new PDL book. PDL is especially suitable for scientists. For those not in the know, 'PDL gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing.' Commercial languages used for the same purpose include MATLAB and IDL."

First time accepted submitter Cyberax writes "After 30 years of drilling and weeks of media attention the Antarctic underground lake Vostok has been reached by Russian scientists (translated article). Deep drilling in the vicinity of Vostok Station in Antarctica began in the 1970s, when the existence of the reservoir was not yet known. Scientists are beginning paleoclimatic studies and further exploration of the lake will continue in 2013-2014."

Hugh Pickens writes "Space.com reports that an online petition directed at the USPS and its Citizen Stamp Advisory Committee (CSAC) hopes to collect 100,000 signatures or more by March 13, the 82nd anniversary of the announcement of Pluto's discovery as the New Horizons robotic spacecraft gets closer to flyby Pluto and its moons in 2015. 'This is a chance for us all to celebrate what American space exploration can achieve though hard work, technical excellence, the spirit of scientific inquiry, and the uniquely human drive to explore,' reads the petition. Whether or not the New Horizons team is successful in getting the USPS to honor their spacecraft's mission, the probe will have delivered a stamp to Pluto. New Horizons includes nine stowaways including one of the 1991 'Not Yet Explored' Pluto stamps together with other mementos including a Florida quarter, a small container with an ounce of the ashes of Clyde Tombaugh, discoverer of Pluto, and a small segment of 2004 Ansari X Prize winner SpaceShipOne, the first privately-funded crewed spacecraft. 'Why nine mementos? I bet you can guess,' says Dr. Alan Stern, New Horizons' Principal Investigator adding why he wanted to send one of the Pluto stamps on the mission. 'Pluto may not have been explored when that stamp set came out, but we were going to conquer that,' says Stern. 'I wanted to fly it as a sort of 'in your face' thing.'"
