Why Cell Phone Bans Don't Work 335

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."

Do Antibiotics Contribute To Obesity? 252

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."

Cats Not Linked To Brain Cancer After All 102

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.

HP Hires Ex-Nokia Exec, Spins Off WebOS, Reportedly Returning To Tablets 128

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.

How To Line a Thermonuclear Reactor 184

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."

Scientists Store Entire Textbook In DNA 160

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."

Bill Gates Wants To Reinvent the Toilet 338

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.

First Mummies May Have Been Inspired by Field of Corpses 78

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."

Red Hat Releases Preview Version of Open Stack Distribution 37

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."

Beware the Nocebo Effect 239

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."

'Smart Fingertips' Pave Way For Virtual Sensations 69

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."

CDE Open Sourced 263

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."

Study Finds Human Teeth are as Tough as Shark Teeth 85

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."

Open WebOS Releases Core Apps; Reveals Touchpad Won't Be Supported 49

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."

The HP Memristor Debate 62

New submitter AaronLS writes "There has been a debate about whether HP has or has not developed a memristor. Since it's something fairly different from existing technologies, and similar in many ways to a memristor, I think they felt comfortable using the term. However, the company has been criticized for using that labeling by former U.S. patent officer Blaise Moutett. On the other hand, had HP created a new, unique label, they would have probably gotten flack for pretending it's something new when it's not. Will anything positive come from this debate? Electrical engineering analyst Martin Reynolds sums it up nicely: 'Is Stan Williams being sloppy by calling it a "memristor"? Yeah, he is. Is Blaise Moutett being pedantic in saying it is not a "memristor"? Yeah, he is. [...] At the end of day, it doesn't matter how it works as long as it gives us the ability to build devices with really high density storage.'"

Being Honest In Exit Interviews Is Pointless 550

Esther Schindler writes "Say that you're leaving a job, either on your own volition or because they decided it was time for you to 'pursue other opportunities.' Before you leave, the HR department wants to chat with you about the employment experience, in an exit interview. 'Oh goodie,' you think. 'Now I can really tell them what I really feel.' Don't do it. If your employer couldn't find the time to ask you what was good or bad about working at the company while you were still working there, writes Lisa Vaas, why bother with honesty and potentially burned bridges now? (If they did ask, give them constructive feedback before you leave this job; they deserve it). Discuss."

Open Compute Project Driving Open-Source Hardware Development 29

The Open Compute Project was launched by Facebook early last year to facilitate collaborative development of highly-efficient computing infrastructure. They wanted to make datacenters cheaper and less energy-intensive to operate. Since then, many industry heavyweights have joined up, and the effects of the project are becoming evident in how companies buy hardware. "Instead of the traditional scenario in which the company’s buying decisions are determined by what the Original Equipment Manufacturers (OEM) such as Dell, HP, and IBM are offering, open sourcing hardware give companies the ability to buy the exact hardware they want. Businesses are increasingly more curious about open source, and many of them are already deploying open source tools and the cloud, [Dell's Joseph George said]. They are increasingly looking at open source software as viable alternatives to commercial options. This level of exploration is moving to the infrastructure layer. 'Driving standards is what open source is about,' George added. With specifications at hand, it is possible to manufacture server and storage components that deliver consistent results regardless of who’s in charge of production.

Chicken Vaccines Combine To Produce Deadly Virus 178

stoilis sends this quote from an article at Science: "Vaccines aren't supposed to cause disease. But that appears to be what's happening on Australian farms. Scientists have found that two virus strains used to vaccinate chickens there may have recombined to form a virus that is sickening and killing the animals 'This shows that recombination of such strains can happen and people need to think about it,' says Glenn Browning, a veterinary microbiologist at the University of Melbourne, Parkville, in Australia and one of the co-authors on the paper."
