sciencehabit writes "Computer simulations of tiny robots with rudimentary nervous systems show that, over hundreds of generations, these virtual machines evolve altruistic behaviors. They begin to share small disks — a stand-in for food — with each other so that their comrades' traits are passed on to the next generation. Experts say the study sheds light on why various animals — from bees to humans — help each other out, even when it hurts their own chances to reproduce."

racquetballguy writes "As part of a December 2010 settlement agreement, NVIDIA agreed to provide all owners of laptops containing a defective NVIDIA GPU with a laptop of similar kind and value. In February, NVIDIA announced that a $279 single-core Compaq CQ56 would be provided as a replacement to all laptops — from $2500 dual-core tablet PCs to $2000 17" entertainment notebooks. Ted Frank, from the Center for Class Action Fairness, filed an objection to the court, which was overruled by Judge Ware today. Once again, the consumers of a class action lawsuit lose."

sciencehabit writes "For years, scientists have speculated that armadillos can pass on leprosy to humans, and that they are behind the few dozen cases of the disease that occur in the US every year. Now, they have evidence. A genetic study published in The New England Journal of Medicine shows that US armadillos and human patients share what seems to be a unique strain of the bacterium that causes leprosy. If an armadillo's blood 'got on my tires of my car from running [the animal] over, I would wash it down,' advises one expert. 'And I would not dig in soil that has a lot of armadillo excrement.'"

sciencehabit writes "Kids who score higher on IQ tests will, on average, go on to do better in conventional measures of success in life: academic achievement, economic success, even greater health, and longevity. Is that because they are more intelligent? Not necessarily. New research concludes that IQ scores are partly a measure of how motivated a child is to do well on the test. And harnessing that motivation might be as important to later success as so-called native intelligence."

jbrodkin writes "Facebook, HP, Rackspace, Juniper, Fujitsu and dozens of other organizations have joined a group building a defensive patent portfolio to protect Linux-using members from potential lawsuits. The Open Invention Network (OIN) — founded in 2005 by IBM, NEC, Novell, Phillips, Red Hat and Sony — has acquired 300 Linux-related patents and licenses to 2,000 in total in a bid to protect the Linux community from intellectual property lawsuits. The group added 74 new members this year and is giving a leadership role to Google, which is fighting lawsuits targeting Linux-based Android."

sciencehabit writes "If Tatooine were real, it would probably be filled with black plants and trees. A new study finds that, to maximize energy absorption for photosynthesis, the flora on worlds that orbit two suns may have evolved to use one or more types of light-absorbing pigments that absorb across a broad range of wavelengths, which would tend to make the plant appear black or gray. Although the idea that planets that could host such life may sound far-fetched, such orbs may not be so rare: The team's computer simulations indicate that Earth-like planets can exist in several types of stable orbits in multistar systems. More than one-fourth of the sunlike stars in our galaxy and about half of the long-lived but dim, cool stars called red dwarfs are found in solar systems containing two or more stars, the researchers note."

sciencehabit writes "In a 70-28 vote yesterday, the Tennessee House of Representatives passed HB 368 (PDF), a bill that encourages science teachers to explore controversial topics without fear of reprisal. Critics say the measure will enable K-12 teachers to present intelligent design and creationism as acceptable alternatives to evolution in the classroom. If the bill passes, Tennessee would join Louisiana as the second state to have specific 'protection' for the teaching of evolution in the classroom."

sciencehabit writes "A US vector biologist appears to have accidentally written virological history simply by having sex with his wife after returning from a field trip to Senegal. A study just released in Emerging Infectious Diseases suggests that the researcher, Brian Foy of Colorado State University, passed to his wife the Zika virus, an obscure pathogen that causes joint pains and extreme fatigue. If so, it would be the first documented case of sexual transmission of an insect-borne disease. The curious case also solves a viral mystery that's been going on for years."

Hugh Pickens writes "International Business Times reports that when manufacturers trotted out their Android tablet prototypes during the CES show two months ago, pundits were happy to toll the death knell for the Apple's iPad, but now manufacturers are discovering that simply making a good tablet does not guarantee that it will sell — much to the chagrin of Motorola and its Xoom product. Now it is plain for all to see that Apple's secret weapon is their network of dedicated Apple stores worldwide where dedicated sales people are not only able to better explain its tablet to consumers but Apple also captures more margin than competitors who have to share margin with retail partners. Apparently, we are not going to see a repeat of the Android ambush of the smartphone market where the combined, price, savvy marketing, and modulated supply releases of the iPhone created so much aspirational demand in the market that buyers simply surged at the chance to buy what was perceived to be an equivalent product at lower prices. 'Motorola's Xoom is only the first to face these problems,' writes AA Defensor. 'Soon RIM's Playbook, and HP's TouchPad will hit the shelves and unless they can do something drastic over the short term, it might remain to be an iPad market. But not because they did not build a good product.'"

sciencehabit was one of several readers to tip news of a sunlight-harvesting artificial leaf, writing: "Nearly all the energy we use on this planet starts out as sunlight that plants use to knit chemical bonds. Now, for the first time, researchers at the Massachusetts Institute of Technology have created a potentially cheap, practical artificial leaf that does much the same thing—providing a vast source of energy that's easy to tap. The new device is a silicon wafer about the shape and size of a playing card coated on either side with two different catalysts. The silicon absorbs sunlight and passes that energy to the catalysts to split water into molecules of hydrogen and oxygen. Hydrogen is a fuel that can be either burned or used in a fuel cell to create electricity, reforming water in either case. This means that in theory, anyone with access to water can use it to create a cheap, clean, and available source of fuel."

sciencehabit writes "Piles of garbage left by humans thousands of years ago may have helped form 'tree islands' in the Florida Everglades--patches of relatively high and dry ground that rise from the wetlands. They stand between 1 and 2 meters higher than the surrounding landscape, can cover 100 acres or more, and host two to three times the number of species living in the surrounding marsh. Besides providing habitat for innumerable birds, the islands offer refuge for animals such as alligators and the Florida panther during flood season. The trash piles—a mix of discarded food, charcoal, shell tools, and broken pottery—would have been slightly higher and drier than the surrounding marsh, offering a foothold for trees, shrubs, and other vegetation."

sciencehabit writes "In the 1950s, scientist Stanley Miller conducted a series of experiments in which he zapped gas-filled flasks with electricity. The most famous of these, published in 1952, showed that such a process could give rise to amino acids, the building blocks of proteins. But a later experiment, conducted in 1958, sat on the shelf--never analyzed by Miller. Now, scientists have gone back and analyzed the sludge at the bottom of this flask and found even more amino acids than before--and better evidence that lightning and volcanic gasses may have helped create life on Earth."

Hugh Pickens writes "Kevin O'Brien writes that Deutsche Telekom's announcement to sell its American wireless unit, T-Mobile USA, to AT&T for $39 billion ended a decade-long foray into the American market that was undermined, in part, by the advent of the iPhone (reg. may be required). Deutsche Telekom had been generating decent sales from its American operation, but after the iPhone went on sale, sold exclusively at first for AT&T in the United States, T-Mobile USA began to lose its most lucrative customers: those on fixed, monthly plans, who defected to its larger American rivals — AT&T and Verizon Wireless. 'The iPhone effect cannot be underestimated in this decision,' says analyst Theo Kitz. "Without being able to sell the iPhone, T-Mobile was in an unsustainable position and T-Mobile USA became a problem child." Ironically, AT&T's acquisition won't help T-Mobile customers get access to the iPhone anytime soon, as T-Mobile will remain independent, albeit under AT&T's stewardship, for around a year, and won't offer the iPhone to its customers during that period."

sciencehabit writes "Most male mammals wield a penis covered with spines made of keratin, the same material that forms fingernails, to sweep out competitors' sperm and irritate a female into ovulating. Even chimpanzees, our closest relatives, have penile spines. So why don't men? A new study suggests that this feature disappeared due to a chunk of DNA that went missing after our evolutionary divergence from chimps. The researchers have identified another DNA deletion that may have contributed to humans' bigger brains."

Stenchwarrior writes "Hewlett-Packard's chief executive officer Leo Apotheker announced that WebOS will be on every PC that HP ships in 2012. The move is intended to attract more developers and push the operating system from mobile devices onto desktops. Apotheker made the announcement during a presentation to HP's staff in India, according to a report by Bloomberg. It's not likely that WebOS will supplant existing operating systems on PCs, but rather would run on top of Windows to be able to launch WebOS apps. HP had previously announced its plans to push WebOS onto PCs last month, but, at the time, the company didn't reveal the scope of its commitment to the operating system. We now know that HP means each and every PC it sells starting in 2012 will have WebOS installed."

Norsefire writes "After teasing it last year, HP's Phil McKinney has announced the 'Metal Watch', the device that will act as the aggregation point of your HP/WebOS devices. McKinney claims that it will unify your Pre, Touchpad, Notebook, Desktop, and, bizarrely, your printer."

An anonymous reader writes "Computer manufacturers have recently come under fire for the continued practice of shipping machines with excessive bloatware. Software preinstalled on some recent HP laptops was worse than normal though, consuming anywhere from 25-99% CPU by making incessant WMI queries, resulting in overheating laptops and reduced battery life. Users on a computer Q&A site did some sleuthing, and revealed that HP Wireless Assistant — software which does nothing but tell the user when their WiFi adapter is turned on or off — was causing the problem. According to an HP support forum, the problem is fixed in later versions, but thousands of laptops have the software installed, and the software does not get updated automatically."

Kilrah_il writes "WebOS Internals Group is the central repository for all the homebrewing done on the WebOS platform, including apps, patches and kernels. Recently it became clear that server infrastructure would fall behind future progress in the WebOS world. 'So they asked HP's Phil McKinney, who has arranged to donate an HP Proliant DL385 2u server with 32 gigs of RAM and 8 terabytes of disk space... Notably, this is a straight-up donation, no strings attached — so WebOS Internals will remain how they always have: completely independent from the company whose OS they hack on.'"

jfruhlinger writes "As had been expected, Hewlett-Packard unveiled new webOS-based smartphones and a webOS tablet today. But in a bit of a shock, the company also announced that webOS would be coming to HP PCs. Whether this is happening in specialized products only or HP plans a wholesale repudiation of Windows, it's definitely a bold move."

alphadogg writes "Networking rivals HP and Cisco have abandoned their common ground in data center switching, with HP accusing Cisco of diverting an IEEE standard and Cisco insisting that customers drove the change. At issue are two as-yet unratified standards in the IEEE for data center switching that were being defined in concert but are now diverging: IEEE 802.1Qbg and 802.1Qbh."
