sciencehabit writes "Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew what it was made of or exactly how it worked. Now a team of researchers has found a single iron atom at the head of the spike, a discovery that suggests phages enter bacteria in a different way than surmised (abstract)."

sciencehabit writes "New research suggests that the upper classes are more likely to behave dishonorably than those lower on the economic spectrum. The rich are more likely to cheat, steal, and even disobey traffic laws than those with less money and power (abstract). Curiously, in one experiment, Prius drivers also behaved badly, regardless of their wealth."

sciencehabit writes "Men typically produce working sperm as long as they live, but most textbooks say female mammals are born with all the egg cells, or oocytes, they will ever have. Since 2004, however, reproductive biologist Jonathan Tilly of Massachusetts General Hospital in Boston has challenged that conventional wisdom, arguing that in mice—and perhaps also in humans—there must be an ongoing source of new eggs. Today, Tilly and his colleagues report isolating rare cells in ovarian tissue from adult women that can grow in lab dishes and form immature oocytes. The potential egg stem cells could help scientists devise new ways to help rescue the fertility of women who have to undergo cancer treatments or who suffer from premature menopause."

sciencehabit writes "The CERN particle physics laboratory in Geneva has confirmed Wednesday's report that a loose fiber-optic cable may be behind measurements that seemed to show neutrinos outpacing the speed of light. But the lab also says another glitch could have caused the experiment to underestimate the particles' speed. The other effect concerns an oscillator that gives its readings time stamps synchronized to GPS signals. Researchers think correcting for an error in this device would actually increase the anomaly in neutrino velocity, making the particles even speedier than the earlier measurements seemed to show."

smolloy writes "It would appear that the hotly debated faster-than-light neutrino observation at CERN is the result of a fault in the connection between a GPS unit and a computer. This connection was used to correct for time delays in the neutrino flight, and after fixing the correction the researchers have found that the time discrepancy appears to have vanished."

kodiaktau writes "Google is working to deliver a heads-up display allowing users access to email, maps and other tools through a wearable interface. According to the NY Times' sources, the device will be available later this year, and sell for prices comparable to smartphones. 'The people familiar with the Google glasses said they would be Android-based, and will include a small screen that will sit a few inches from someone’s eye. They will also have a 3G or 4G data connection and a number of sensors including motion and GPS. ... The glasses will have a low-resolution built-in camera that will be able to monitor the world in real time and overlay information about locations, surrounding buildings and friends who might be nearby, according to the Google employees. The glasses are not designed to be worn constantly — although Google expects some of the nerdiest users will wear them a lot — but will be more like smartphones, used when needed.'"

New submitter egparedes points out a post dissecting webOS and highlighting the things it did right, in the hopes that developers for other mobile operating systems will use them as inspiration. Quoting: "webOS isn't quite dead yet. It's just being open-sourced, which, when it happens to commercial software, often turns out to be the digital equivalent of being reanimated as a walking corpse in a George Romero movie. ... Of course, it's not assured that this is the end of webOS. Maybe open-sourcing it will be the best thing that ever happened to webOS. But maybe it just means that HP doesn't care anymore, and that webOS won't receive much attention anymore. This would be unfortunate, because webOS is one of the few current mobile operating systems that are actually a joy to use. It's been hurt by HP's incompetent management, rather than any egregious faults of its own. The least we can do now is to keep its best ideas alive, even if webOS itself won't make it."

New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

swandives writes "WebOS could be an important player in the long run as an open-source mobile OS, because Android could become closed source with Google's purchase of Motorola Mobility, Hewlett-Packard CEO Meg Whitman said during a speech at the HP Global Partner conference in Las Vegas. It may take up to four years for the complete impact of webOS to be felt, Whitman said. HP has said it would release WebOS — originally developed by Palm for phones and tablets — to the open-source community. The company bought Palm in 2010 but late last year announced it will not make devices that use the software."

jfruh writes "HP reversed its decision to spin off its PC business, but it's still left with the question of how to make money in a commodity business selling standard-issue machines manufactured overseas. One idea they're contemplating: improved customer service. If you buy an HP 'Elite' PC and have problems, you won't have to phone into a tech support call center where an entry-level drone reads off a script and tells you to reboot the machine; you'll have access to a specific support tech who will work with you as long as you own the computer."

sciencehabit writes "The average American uses enough water each year to fill an Olympic-sized swimming pool, and global agriculture consumes a whopping 92% of all fresh water used annually. Those are the conclusions of the most comprehensive analysis to date of global water use, which also finds that one-fifth of humankind's water consumption flows across international borders as 'virtual water' — the water needed to produce a commodity, such as meat or electronics, if the ultimate consumers were to make it themselves rather than outsource its growth or manufacture."

An anonymous reader writes "If you grab all the public keys you can find on the net, then you might expect to uncover a few duds — but would you believe that 2 out of every 1000 RSA keys is bad? This is one of the interesting findings in the paper 'Ron was wrong, Whit is right' by Lenstra, Hughes, Augier, Bos, Kleinjung and Wachter. Quoting from the paper's abstract: 'We performed a sanity check of public keys collected on the web. Our main goal was to test the validity of the assumption that different random choices are made each time keys are generated. We found that the vast majority of public keys work as intended. A more disconcerting finding is that two out of every one thousand RSA moduli that we collected offer no security. Our conclusion is that the validity of the assumption is questionable and that generating keys in the real world for "multiple-secrets" cryptosystems such as RSA is significantly riskier than for "single-secret" ones such as ElGamal or (EC)DSA which are based on Diffie-Hellman.'" For a layman's interpretation of the research, the NY Times has an article about the paper. Update: 02/15 01:34 GMT by S : Security researcher Dan Kaminsky has commented on the paper, saying that while the survey work itself is good, it doesn't necessarily support the paper's thesis. He writes, "On the most basic level, risk in cryptography is utterly dominated, not by cipher selection, but by key management. The study found 12,720 public keys. It also found approximately 2.94 million expired certificates. And while the study didn’t discuss the number of certificates that had no reason to be trusted in the first place (being self signed), it did find 5.4M PGP keys. It does not matter the strength of your public key if nobody knows to demand it."

sciencehabit sends this excerpt from ScienceInsider: "One of the big three research agencies appears to be lagging behind its doubling peers in the president's 2013 budget request released this morning. The $4.9 billion budget of the Department of Energy's Office of Science would rise by 2.4%, to $5 billion. In contrast, the National Science Foundation would receive a nearly 5% boost, to $7.37 billion, and the National Institute of Standards and Technology a hike of 13%, to $860 million. These three agencies were originally singled by President George W. Bush in 2006 for a 10-year budget doubling, a promise that President Barack Obama and Congress have repeatedly endorsed despite the current tough economic times. ... Obama is asking for a 1% increase in overall federal spending on research, to $140 billion. Within that total, the White House seeks a similar 1% hike in the $30 billion devoted to basic research."

sciencehabit writes "Petroleum geologists have long used air guns in their search for oil and gas deposits. Sudden blasts from the devices generate seismic waves that they use to map underground rock formations. Could the same technique be used to study earthquakes? A team of Chinese scientists thinks so. The researchers have designed an air gun that could be useful in monitoring changes in stress buildup along fault zones."

sciencehabit writes "Researchers have created the world's thinnest pane of glass. The glass, made of silicon and oxygen, formed accidentally when the scientists were making graphene, an atom-thick sheet of carbon, on copper-covered quartz. They believe an air leak caused the copper to react with the quartz, which is also made of silicon and oxygen, producing a glass layer with the graphene. The glass is a mere three atoms thick — the minimum thickness of silica glass—which makes it two-dimensional. The team notes that the structure 'strikingly resembles' a diagram drawn by a glass theorist attempting to unravel its structure back in 1932. Such ultra-thin glass could be used in semiconductor or graphene transistors." See Nano Letters for an abstract (and another picture) to the paywalled article.

judgecorp writes "The OpenStack open source cloud project has removed Hyper-V from its infrastructure as a service (IaaS) framework, saying Microsoft's support for its hypervisor technology is 'broken.' This will embarass Microsoft, as major partners such as Dell and HP support OpenStack, along with service providers such as Internap." Adds reader alphadogg, this "means the code will be removed when the next version of OpenStack, called Essex, is released in the second quarter."

sciencehabit writes "A new analysis reveals the intricacies of spider web design, showing how the unique properties of its silk turn webs into flexible yet strong traps. Computer simulations reveal that heavy forces spread over the entire net rather than stay local. Real spider silk can be either stretchy or stiff at different times, which produces threads that flex and then snap in just the right way to avoid wrecking nearby spokes."

sciencehabit writes with this excerpt from Science: "The first plants to colonize land didn't merely supply a dash of green to a drab landscape. They dramatically accelerated the natural breakdown of exposed rocks, according to a new study, drawing so much planet-warming carbon dioxide (CO2) from the atmosphere that they sent Earth's climate spiraling into a major ice age."

slew writes "This is a followup to this earlier story about 2 of 3 of Rambus's 'critical' patents being invalidated. Apparently now it's a hat-trick." There's something that seems unsavory and wasteful about a business environment in which a company's stock value "fluctuates sharply on its successes and failures in patent litigation and licensing." The linked article offers a brief but decent summary of the way Rambus has profited over the years from these now-invalidated patents.

sciencehabit writes "The North Star, a celestial beacon to navigators for centuries, may be slowly shrinking, according to a new analysis of more than 160 years of observations. The data suggest that the familiar fixture in the northern sky is shedding an Earth's mass worth of gas each year."
