sciencehabit writes "Slash your food intake and you can live dramatically longer — at least if you're a mouse or a nematode. But a major study designed to determine whether this regimen, known as caloric restriction, works in primates suggests that it improves monkeys' health but doesn't extend their lives. Researchers not involved with the new paper say the results are still encouraging. Although the monkeys didn't evince an increase in life span, both studies show a major improvement in 'health span,' or the amount of time before age-related diseases set in. 'I certainly wouldn't give up on calorie restriction as a health promoter' based on these findings, says molecular biologist Leonard Guarente of the Massachusetts Institute of Technology in Cambridge."

Esther Schindler writes "Ready for a nostalgic trip into the wayback? We had floppy disks long before we had CDs, DVDs, or USB thumb-drives. Here's the evolution of the portable media that changed everything about personal computing. 'The 8-inch drive began to show up in 1971. Since they enabled developers and users to stop using the dreaded paper tape (which were easy to fold, spindle, and mutilate, not to mention to pirate) and the loathed IBM 5081 punch card. Everyone who had ever twisted a some tape or—the horror!—dropped a deck of Hollerith cards was happy to adopt 8-inch drives. Besides, the early single-sided 8-inch floppy could hold the data of up to 3,000 punch cards, or 80K to you.'"

Barence writes "Lexmark has announced it will stop making inkjet printers and cut 1,700 jobs as part of a cost-cutting restructuring move. Lexmark will stop all inkjet development worldwide by 2013, and close its Philippines-based inkjet supplies manufacturing plant by 2015. This will provide annual savings of $85 million, rising to $95 million by 2015. The total restructuring cost before tax is expected to be $160 million. The company is also looking into the possible sale of its inkjet-related technology." I know there are some purposes for which inkjets are good (modern home photo printing can be insanely good, and we've featured a lot of cool projects which use inkjets to print sensors, solar cells, antennae, and more), but I get just a little queasy whenever I see an inkjet printer purchased by an innocent friend or family member who doesn't realize quite how much it will end up costing them in the long run.

nmpost writes in with a story about how hard it is to be a successful PC company in today's world. "Hewlett-Packard Co. used to be known as a place where innovative thinkers flocked to work on great ideas that opened new frontiers in technology. These days, HP is looking behind the times. Coming off a five-year stretch of miscalculations, HP is in such desperate need of a reboot that many investors have written off its chances of a comeback. Consider this: Since Apple Inc. shifted the direction of computing with the release of the iPhone in June 2007, HP's market value has plunged by 60 percent to $35 billion. During that time, HP has spent more than $40 billion on dozens of acquisitions that have largely turned out to be duds so far. HP might have been unchallenged for the ignominious title as technology's most troubled company if not for one its biggest rivals, Dell Inc. Like HP, Dell missed the trends that have turned selling PCs into one of technology's least profitable and slowest growing niches. As a result, Dell's market value has also plummeted by 60 percent, to about $20 billion, since the iPhone's release."

MrSeb writes "Logitech has released its first washable keyboard. We're not just talking about 'splash proof' either — you can take the K310, immerse it in up to 30cm of water (12in), and give it a good scrub. The only limitation is you can only use standard washing up liquid — oh, and Logitech says you should try to keep the USB connector out of the water, too. Once you've washed the keyboard, simply leave it to dry. The user guide says it takes eight hours to air dry, and that you shouldn't use a hair dryer. There are actually drainage holes on the backside of the K310, to help speed things along. This isn't the first washable keyboard — HP and Kensington have both had models on the market for a while — but the K310 does seem to be the first reasonably attractive, consumer-oriented washable keyboard. It goes on sale at the end of the month for $40."

sciencehabit writes "You can take the driver away from the cell phone, but you can't take the risky behavior away from the driver. That's the conclusion of a new study, which finds that people who talk on their phones while driving may already be unsafe drivers who are nearly as prone to crash with or without the device. The findings may explain why laws banning cell phone use in motor vehicles have had little impact on accident rates."

sciencehabit writes "Farmers have long used antibiotics to make cows, pigs, and turkeys gain weight faster. Now, scientists claim that receiving antibiotics early in life may also make children grow fat (abstract). The researchers believe the drugs change the composition of the bacterial population in the gut in a crucial developmental stage that may have a long-lasting impact."

sciencehabit writes with good news for cat owners everywhere. From the article: "Last year, cat owners got a scare when a team of French researchers reported a possible link between felines and brain cancer. Cat feces can harbor a single-celled parasite called Toxoplasma gondii, and the scientists found that nations with higher rates of human T. gondii infection also have higher incidences of brain cancer. A new study challenges those findings [paywalled after the first view]. Scientists examining a cohort of more than 600,000 British women found that cat owners were no more likely to develop brain cancer than their cat-free counterparts, despite their presumably greater risk of exposure to T. gondii." The study in question mostly just found that T. gondii infection rates aren't correlated with cat ownership after all, but there's still no word on whether our friend the parasite causes cancer or not.

judgecorp writes "Hewlett-Packard is returning to tablets with a new unit that aims to make consumer devices under the leadership of former Nokia executive Alberto Torres." This particular Ex-Nokia exec was part of the Meego division. The newly founded HP Mobility will focus on consumer tablets; 'business' tablets (presumably running Windows 8) will remain in their current division. With the recent spinning off of the webOS team into Gram this might mean new webOS hardware.

sciencehabit writes "One of the biggest question marks hanging over the ITER fusion reactor project — a giant international collaboration currently under construction in France — is over what material to use for coating its interior wall. After all, the reactor has to withstand temperatures of 100,000C and an intense particle bombardment. Researchers have now answered that question by refitting the current world's largest fusion device, the Joint European Torus (JET) near Oxford, U.K., with a lining akin to the one planned for ITER. JET's new 'ITER-like wall,' a combination of tungsten and beryllium, is eroding more slowly (PDF) and retaining less of the fuel than the lining used on earlier fusion reactors, the team reports."

sciencehabit writes with this mind-boggling bit from Science Magazine: "When it comes to storing information, hard drives don't hold a candle to DNA. Our genetic code packs billions of gigabytes into a single gram. A mere milligram of the molecule could encode the complete text of every book in the Library of Congress and have plenty of room to spare. All of this has been mostly theoretical—until now. In a new study, researchers stored an entire genetics textbook in less than a picogram of DNA — one trillionth of a gram — an advance that could revolutionize our ability to save data."

redletterdave writes "Bill Gates, the man responsible for bringing software to the masses with Microsoft and Windows, has plans to reinvent and popularize another industry: Sanitation. Gates, whose philanthropic efforts have helped bring clean water and resources to developing countries via the foundation created by he and his wife Melinda, said at the 'Reinvent The Toilet Fair' in Seattle on Wednesday that he plans to build a toilet that's better suited to developing countries in an effort to cut down on disease and death in those regions. 'Inventing new toilets is one of the most important things we can do to reduce child deaths and disease and improve people's lives,' Gates said. 'It is also something that can help wealthier countries conserve fresh water for other important purposes besides flushing.'" Science Insider has some information on the winning designs from this year.

sciencehabit writes with a story about a field strewn with corpses in shallow graves. From the article: "Trekking through Chile's Atacama Desert 7000 years ago, hunter-gatherers known as the Chinchorro walked in the land of the dead. Thousands of shallowly buried human bodies littered the earth, their leathery corpses pockmarking the desolate surroundings. According to new research, the scene inspired the Chinchorro to begin mummifying their dead, a practice they adopted roughly 3000 years before the Egyptians embraced it."

hypnosec writes "Red Hat has announced the availability of a preview version of its OpenStack Distribution that would enable it to compete with the likes of Amazon which is considered one of the leaders in infrastructure-as-a-service cloud services. The enterprise Linux maker was a late entrant into the OpenStack world where players like Rackspace, HP and Internap have already made their mark. Red Hat's OpenStack distribution enterprises can build and manage private, public, and hybrid infrastructure-as-a-service clouds. These companies will not only be competing with the likes of Amazon, but will also be competing against themselves to get a bite out of the IaaS cloud. What started as a project has quickly developed into an open source solution that enables organizations to achieve performance, features and greater functionality from their private and/or public clouds. The announcement of OpenStack Foundation acted as a catalyst toward the fast-paced development of the platform."

An article at the NY Times looks at research into the "nocebo" effect. Named after the placebo effect, it's the term for when patient expectations do harm, rather than good. "When a patient anticipates a pill’s possible side effects, he can suffer them even if the pill is fake." The article describes several instances of patients getting the placebo in a drug trial, but reporting the expected side effects of the drug, rather than the benefits or nothing at all. Quoting: "Consider the number of people in medical trials who, though receiving placebos, stop participating because of side effects. We found that 11 percent of people in fibromyalgia drug trials who were taking fake medication dropped out of the studies because of side effects like dizziness or nausea. Other researchers reported that the discontinuation rates because of side effects in placebo groups in migraine or tension drug trials were as much as 5 percent. Discontinuation rates in trials for statins ranged from 4 percent to 26 percent. ... In one remarkable case, a participant in an antidepressant drug trial was given placebo tablets — and then swallowed 26 of them in a suicide attempt. Even though the tablets were harmless, the participant's blood pressure dropped perilously low."

sciencehabit writes "Imagine feeling like you're lifting a 50-kilogram weight just by pulling at thin air. That's just one of the possible applications of new 'smart fingertips' created by a team of nanoengineers. The electronic fingers mold to the shape of the hand, and so far the researchers have shown that they can transmit electric signals to the skin. The team hopes to one day incorporate the devices into a smart glove that creates virtual sensations, fooling the brain into feeling everything from texture to temperature."

First time accepted submitter christurkel writes "CDE, the Common Desktop Project, has been open sourced by the Open Group. CDE was created by a collaboration of Sun, HP, IBM, DEC, SCO, Fujitsu and Hitachi. You can find the source here. It has been tested on Debian Squeeze and Ubuntu. Testers are encouraged to join the project. Motif will follow in a few months once some legal issues are sorted out."

sciencehabit writes "Don't feel inadequate. Even though your teeth are largely composed of a mineral softer than that found in sharks, new tests suggest that they're just as tough. In sharks, the material coating the teeth is largely composed of fluoroapatite, a fluoridated phosphate mineral that in its pure form is harder than the hydroxyapatite found in the enamel of human teeth. But by pressing tiny metallic pyramids into the surfaces of teeth from a shortfin mako shark and a tiger shark, researchers found that the enameloid coating on shark teeth is no harder than that of the enamel on a human wisdom tooth. The teeth are, in fact, of comparable hardness because their surfaces aren't pure mineral but instead are made of mineral crystals bound together with proteins so that the material doesn't shatter under a sudden impact."

Caught via the H is news that more components of webOS have been released: "The core applications provide a comprehensive set of platform user applications, including Email, Calendar, Contacts, Memos, Accounts, Clock and Calculator." Additionally, HP has opened up the development branch of system manager: "We are excited to open up the active development branch of our upleveled System Manager. This major upgrade incorporates the latest QtWebKit and Qt technologies in an improved architecture. Modern QtWebKit now underlies all applications, providing state-of-the-art support for HTML rendering and I/O. The latest stable release of Qt has been integrated across the system, eliminating alternate rendering paths and providing a clean base for the future. These changes bring enhanced stability and performance to Open webOS." As always, source can be had from the Open webOS github. A bit of bad news for existing device owners, however: "...we are aiming for support on future hardware platforms where SoC’s support Linux 3.3+ kernel and where open source replacements for proprietary components are integrated. Existing devices cannot be supported because of those many proprietary components, including graphics, networking and lack of drivers for a modern kernel." Existing device owners will have to live with the "webOS community edition."

angry tapir writes "A California court has ordered Oracle to continue porting its software to the Intel Itanium chips used by Hewlett-Packard in a number of its servers. Last year, Oracle, which competes with HP in the hardware market but shares many customers with the vendor, announced it would cease supporting Itanium. HP filed suit in June 2011, maintaining that Oracle was contractually bound to continue supporting Itanium."
