An anonymous reader writes "A team of researchers reports they can't reproduce the most important claim from 2010's controversial 'arsenic bacteria' paper — they find no arsenic in the bug's DNA. Meanwhile, other scientists are looking at different aspects of the bug and at arsenic in biology in general."

ForgedArtificer writes "A recent eruption on the sun will be exposing Earth to the strongest radiation storm seen since 2005. [The storm] will potentially disrupt communications and put high-flyers at risk of radiation exposure." Says Spaceweather.com: "On the NOAA scale of radiation storms, this one ranks S3, which means it could, e.g., cause isolated reboots of computers onboard Earth-orbiting satellites and interfere with polar radio communications." According to the Christian Science Monitor, "NOAA's Space Weather Prediction Center has issued a geomagnetic storm watch, and the agency's deputy, Kathy Sullivan, said that polar flights are expected to be re-routed."

astroengine writes "On Friday, the sun hurled a coronal mass ejection (CME) at our planet that sparked a strong geomagnetic storm and beautiful aurorae at high latitudes. Late on Sunday (EST), the sun unleashed yet another Earth-bound CME after an M9 flare erupted over a particularly active sunspot region — the CME is expected to hit Earth on Tuesday and Mars on Wednesday. This series of flares and CMEs have ignited the strongest period of solar storms since 2005, according to an NOAA space weather advisory."

milbournosphere writes "Russia and NASA are reportedly in talks to create a base on the Moon. They're looking to create either a facility on the Moon itself or a permanent space station in orbit around the moon. 'We don't want man to just step on the Moon,' agency chief Vladimir Popovkin said in an interview with Vesti FM radio station. 'Today, we know enough about it. We know that there is water in its polar areas,' he added. 'We are now discussing how to begin [the Moon's] exploration with NASA and the European Space Agency.'"

flergum writes "Leonid Ksanfomaliti, an astronomer based at the Space Research Institute of Russia's Academy of Sciences, analyzed photographs taken by a Russian landing probe during 1982 and claims to have found signs of life. Ksanfomaliti says the Russian photographs depict objects resembling a 'disk,' a 'black flap' and a 'scorpion.'"

MrSeb writes "Researchers from Imperial College London and A*STAR in Singapore have shown off a terahertz antenna that's just 100 nanometers across — about 30,000 times smaller than existing terahertz antennae — and two orders of magnitude stronger than other T-ray beam-forming techniques. T-rays are a lot like EHF (extremely high frequency), which is used by millimeter wave scanners in airports, medical imaging, and emerging wireless networking standards like WiGig — but stronger, faster, and more detailed. Where EHF radiation can see through your clothes, T-rays can penetrate a few millimeters of skin. Furthermore, because atoms and molecules have a unique terahertz-range signature, T-ray scanners can detect toxic substances, bombs, drugs — or even cancerous tumors under your skin. Most importantly, though, due to the nano scale of these antennae, it's possible to create huge antennae arrays on a single silicon chip, meaning hand-held T-ray scanners are now a possibility. In the not so distant future, every household might have a Star Trek-like tricorder capable of detecting cancer or other diseases."

arisvega writes in with a story about an international organization that is trying to come up with options to save the planet from a large asteroid or comet collision. "NEOShield is a new international project that will assess the threat posed by Near Earth Objects (NEO) and look at the best possible solutions for dealing with a big asteroid or comet on a collision (PDF) path with our planet. The effort is being led from the German space agency's (DLR) Institute of Planetary Research in Berlin, and had its kick-off meeting this week. It will draw on expertise from across Europe, Russia and the US. It's a major EU-funded initiative that will pull together all the latest science, initiate a fair few laboratory experiments and new modelling work, and then try to come to some definitive positions. Industrial partners, which include the German, British and French divisions of the big Astrium space company, will consider the engineering architecture required to deflect one of these bodies out of our path."

PolygamousRanchKid writes "Seaweed may well be an ideal plant to turn into biofuel. It grows in much of the two thirds of the planet that is underwater, so it wouldn't crowd out food crops the way corn for ethanol does. Because it draws its own nutrients and water from the sea, it requires no fertilizer or irrigation. Most importantly for would-be biofuel-makers, it contains no lignin—a strong strand of complex sugars that stiffens plant stalks and poses a big obstacle to turning land-based plants such as switchgrass into biofuel. Researchers at Bio Architecture Lab, Inc., (BAL) and the University of Washington in Seattle have now taken the first step to exploit the natural advantages of seaweed. They have built a microbe capable of digesting it and converting it into ethanol or other chemicals. Synthetic biologist Yasuo Yoshikuni, a co-founder of BAL, and his colleagues took Escherichia coli, a gut bacterium most famous as a food contaminant, and made some genetic modifications that give it the ability to turn the sugars in an edible kelp called kombu into fuel."

judgecorp writes "Researchers at Vienna's Quantum Science and Technology Center have proposed that 'blind' quantum computing could be carried out securely in the cloud. When (if?) quantum computers are developed, they will be very fast, but not everyone will have them. Blind quantum computing will be useful, because it shows that users can encode 'qubits' and send them to a shared quantum computer to be worked on — without the quantum computer having any knowledge of what the data is (abstract). The data also cannot be decoded form the qubit while it is in transit. It's good to know that quantum computers will be secure when they exist. At the moment, of course, they are even more secure, by virtue of their non-existence."

sciencehabit writes "When it comes to Earth's rotation, you might think geophysicists have pretty much everything figured out. Not quite. In order to explain some variations in the way our planet spins, Earth's mantle — the layer of hot, softened rock that lies between the crust and core — must conduct electricity, an ability that the mantle as we know it shouldn't have. Now, a new study (academic paper) finds that iron monoxide, which makes up 9% of the mantle, actually does conduct electricity just like a metal, but only at temperatures and pressures found far beneath the surface."

alphadogg writes "Google is continuing to weed out its services and on Friday announced it will shut down Picnik, Google Message Continuity and Needlebase and make changes to some other services. Google acquired Seattle-based Picnik in 2010, saying it would integrate the photo editing service with its own Picasa. 'We're retiring the service on April 19, 2012, so the Picnik team can continue creating photo-editing magic across Google products,' Dave Girouard, vice president of product management for Google, wrote in a blog post Friday." A positive change to come out of this is that Google is open-sourcing Sky Map, and will be collaborating with Carnegie Mellon University to continue development.

oztiks writes "Lawyer Karen Sandler's heart condition means she needs a pacemaker to ward off sudden death. Instead of trusting that the vendor will create a flawless platform for the device to operate, Sandler has demanded to see the device's source code. Sandler's reasoning brings into question the device's reliably, stability, and oddly enough, security."

astroengine writes "Researchers from Icarus Interstellar Inc. and General Propulsion Science have announced their intention to pursue the development of Nuclear Thermal Rockets and other fission-based space technologies. The aim? To revolutionize space travel, ultimately paving the way to the goal of sending a probe to another star."

The Bad Astronomer writes "Last year was the 9th hottest year out of the past 130, according to NASA and the NOAA. That's no coincidence: nine out of the ten hottest years on record have been since the year 2000. It's long past time to face facts: the Earth is getting hotter, and to deny it is an exercise in fantasy."

smitty777 writes "Highlighting another unique way to use cutting edge DNA technology, the U.S. Department of Defense has a new weapon in its efforts to combat counterfeit parts: plant DNA. This article at Wired discusses how plant DNA can be used to make an almost unique code (1 in 1 trillion) for parts identification. A graphic shows some of the ways this could be done: bolts with DNA-marked coating, invisible bar codes, and fluorescing inks are some of the possible applications. In a similar but unrelated project, World Micro has a different solution to detect counterfeit items in the military that have been 'blacktopped,' where items have been re-surfaced to allow remarking."

parallel_prankster writes "The Washington Post reports that a huge sunspot unleashed a blob of charged plasma Thursday that space weather watchers predict will blast past the Earth on Sunday. Satellite operators and power companies are keeping a close eye on the incoming cloud, which could distort the Earth's magnetic field and disrupt radio communications, especially at higher latitudes. The huge blob of charged gas spotted by NASA satellites is speeding toward Earth at more than 2 million mph. The most damaging solar discharges, which are very rare, can move at speeds more than twice that fast. Here's a more detailed article with some animation."

New submitter scibri writes "Researchers working on highly pathogenic H5N1 avian influenza have said they will stop work on the virus for 60 days, to allow them to explain the importance of their work to politicians and the public. Quoting: 'Despite the positive public-health benefits these studies sought to provide, a perceived fear that the ferret-transmissible H5 HA viruses may escape from the laboratories has generated intense public debate in the media on the benefits and potential harm of this type of research. We would like to assure the public that these experiments have been conducted with appropriate regulatory oversight in secure containment facilities by highly trained and responsible personnel to minimize any risk of accidental release.'" Reader Harperdog sends in a related article arguing that we shouldn't be having a debate about the censorship of research, but rather a debate over whether the research should have been allowed in the first place.

PerlJedi writes "The future of innovation in America is the Maker movement. A new project being announced on the Makezine blog aims to bring low cost innovation and alternative manufacturing processes to schools in hopes of turbo-charging the next generation of inventors in the U.S. From the announcement: 'The new Makerspace program, developed by Dale Dougherty of MAKE and Dr. Saul Griffith of Otherlab, will integrate online tools for design and collaboration with low-cost options for physical workspaces where students may access educational support to gain practical hands-on experience with new technologies and innovative processes to design and build projects. The program has a goal of reaching 1000 high schools over four years, starting with a pilot program of 10 high schools in California during the 2012-2013 school year.'"

gManZboy writes "Talk of individually tailored medical treatment isn't pie in the sky. This approach eventually will help us address risk factors even before a disease can invade our cells, and detect preclinical disease before it gets out of hand. What role will medical informatics play in this brave new world? Hint: Little data projects may be as important as big data projects such as gene sequencing. At a recent symposium on personalized medicine, Ezekiel J. Emanuel, MD, chairman of the Department of Medical Ethics and Health at the University of Pennsylvania, questioned whether it would make more sense to target all the lifestyle mistakes that patients make rather than analyze genetic defects. His view: 'Personalized medicine misses the most important fact about modern society--little ill health and premature death is genetic, much more is lifestyle and social.' Is Emanuel a dinosaur or a pragmatist?"

First time accepted submitter CanEHdian writes "MIT news reports on research done resulting in a Faster-than-fast Fourier Transform algorithm. 'At the Association for Computing Machinery's Symposium on Discrete Algorithms (SODA) this week, a group of MIT researchers will present a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform. Under some circumstances, the improvement can be dramatic — a tenfold increase in speed. The new algorithm could be particularly useful for image compression, enabling, say, smartphones to wirelessly transmit large video files without draining their batteries or consuming their monthly bandwidth allotments.'"
