sciencehabit writes "In 1592, a British ship sank near the island of Alderney in the English Channel carrying an odd piece of cargo: a small, angular crystal. Once it was brought back to land, a few European scientists began to suspect the mysterious object might be a calcite crystal, a powerful 'sunstone' referred to in Norse legends which they believe Vikings and other European seafarers used to navigate before the introduction of the magnetic compass. Now, after subjecting the object to a battery of mechanical and chemical tests, the team has determined that the Alderman crystal is indeed a calcite and, therefore, could have been the ship's optical compass. Today, similar calcite crystals are used by astronomers to analyze the atmospheres of exoplanets—perhaps setting the stage for a whole new age of exploration."

An anonymous reader writes "Flash SSDs are non-volatile, right? So how could power failures screw with your data? Several ways, according to a ZDNet post that summarizes a paper (PDF) presented at last month's FAST 13 conference. Researchers from Ohio State and HP Labs researchers tested 15 SSDs using an automated power fault injection testbed and found that 13 lost data. 'Bit corruption hit 3 devices; 3 had shorn writes; 8 had serializability errors; one device lost 1/3 of its data; and 1 SSD bricked. The low-end hard drive had some unserializable writes, while the high-end drive had no power fault failures. The 2 SSDs that had no failures? Both were MLC 2012 model years with a mid-range ($1.17/GB) price.'"

Nerval's Lobster writes "Hewlett-Packard seems more determined than ever to flee the Windows reservation, unveiling a $170 Android tablet, the HP Slate 7. It runs Google Android 4.1, the first version of the 'Jelly Bean' build, which has been ever so slightly outdated by the recent release of Android 4.2. This isn't the first time in recent memory that HP's opted for a Google product over one offered by longtime partner Microsoft. As it helpfully pointed out in a press release, HP has produced a Chromebook running Google's Chrome OS, a largely cloud-dependent operating system for laptops and notebooks. Built around Google services such as Gmail, Chrome OS also offers access to the Chrome Web Store, an online storefront for apps. If HP and other manufacturers increasingly adopt Google's offerings over Windows, it could cause some consternation among Microsoft executives. Microsoft, of course, is pushing Windows 8, which is meant to run on tablets and traditional PCs with equal facility. If it wants the Windows division to continue as a cash cow, it needs manufacturers to adopt that operating system in massive numbers. Android and Chrome OS could make that strategy a lot more difficult."

An anonymous reader writes "LG is set to breathe new life into the webOS platform after the company announced today that it has acquired the software and its intellectual property from HP. The news comes after HP abandoned webOS device and software development in August 2011, then open-sourced the platform so that developers might be able to salvage something from the software that was widely acclaimed, despite the lack of smartphone and tablet sales which it powered. LG now claims complete ownership of the webOS source code, its documentation and webOS websites. It has obtained HP licenses, as well as the patents that Palm transferred to its owner when it was acquired in 2010."

Still, even if you got bit by the HP TouchPad debacle, HP's newly-announced $169 Slate7 tablet could prove hard to resist. Specs-wise, the Slate7 sports an ARM Dual Core Cortex-A9 1.6 GHz processor, 7-inch 1024x600 HFFS screen, Android 4.1 (Jellybean), three-megapixel camera on the back, front-facing VGA camera, 8GB of on-board storage, HP ePrint, Beats Audio, and a micro SD expandable card slot. It measures 197mm x 116mm x 10.7mm thick, and weighs in at 13 ounces. It will be available in the U.S. in April. Engadget has some pics and their initial hands-on take."

silentbrad writes sends this excerpt from a blog post about the history of working from home: "Remote working has existed for centuries. And now is the perfect time for its comeback. ... Prior to the Industrial Revolution, goods were manufactured by contracting individual craftsmen who worked out of their homes. The merchant would drum up sales, and would coordinate the production with at-home sub-contractors. ... This all changed with the Industrial Revolution: production was centralized in factories and cities. For merchant capitalists, this made sense: it was cheaper and more efficient to produce goods in one place, with machinery. ... We've been in the Information Age for at least 25 years. We've made huge leaps in technology. Many of us would describe ourselves as Knowledge Workers: we don't work in factories, we work at desks in front of glowing screens. We don't make goods with physical materials, but rather things made out of bits. The great thing about bits + the internet is that the materials and means needed for production aren't dependent on location. But here's the funny thing: the way work is organized hasn't changed. Despite all these advances, most of us still work in central offices. Employees leave their computer-equipped homes and drive long distances to work at computer-equipped offices. ... CEOs, like Yahoo's Marissa Mayer and Apple's Steve Jobs, think that a central office fosters more innovation and productivity. I think they're wrong. We're still early in the research, but recent studies seem to dispute their claim. ... Managers have developed centuries worth of habits based on the central workplace. The hallmarks of office work (meetings, cubicle workstations, colocation) need to be seen for what they are: traditions we've kept alive since the Industrial Revolution. We need to question these institutions: are they really more innovative and efficient?"

alphadogg writes "Microsoft Azure's cloud outperformed Amazon Web Services in a series of rigorous tests conducted by Nasuni, a storage vendor that annually benchmarks cloud service providers (CSPs). Nasuni uses public cloud resources in its enterprise storage offering, so each year the company conducts a series of rigorous tests on the top CSPs' clouds in an effort to see which companies offer the best performing, most reliable infrastructure. Last year, Amazon Web Services' cloud came out on top, but this year Microsoft Azure outperformed AWS in performance and reliability measures. AWS is still better at handling extra-large storage volumes, while Nasuni found that the two OpenStack powered clouds it tested — from HP and Rackspace — were lacking, particularly at larger scales."

sciencehabit writes "Thanks to a highway-widening project in California's Laguna Canyon, scientists have identified several new species of early toothed baleen whales. The new fossils date to 17 to 19 million years ago, or the early-mid Miocene epoch, making them the youngest known toothed whales. Three of the fossils belong to the genus Morawanocetus, which is familiar to paleontologists studying whale fossils from Japan, but hadn't been seen before in California. These three, along with the fourth new species, which is of a different genus, represent the last known occurrence of aetiocetes, a family of mysticetes that coexisted with early baleen whales. Thus, they aren't ancestral to any of the living whales, but they could represent transitional steps on the way to today's whales."

sciencehabit writes "When it comes to hanging on tight, the lowly mussel has few rivals in nature. Researchers have sought the secrets behind the bivalve's steadfast grip on wet, slippery rock. Now, a researcher says he has used the mollusk's tricks to develop medical applications. These include a biocompatible glue that could one day seal fetal membranes, allowing prenatal surgeons to repair birth defects without triggering dangerous premature labor."

MojoKid writes "If you've paid any attention to the PC industry in the past few years, you're aware that things aren't as rosy as they used to be. After decades of annual growth, major manufacturers like HP and Dell have both either floated the idea of exiting the consumer space (HP) or gone private (Dell). Contrast that with steady growth at companies like Asus and Lenovo, and some analysts think the entire PC industry could move to Asia in the next few years. The ironic part of the observation is that in many ways, this has already happened. Asia-Pacific manufacturers are more focused on the consumer electronics market and better able to cope with low margins thanks to rapid adoption and huge potential customer bases. Apple has proven that high margin hardware can be extremely profitable, but none of the PC OEMs have been willing to risk the R&D costs or carry new products for a significant period of time while they adapt designs and improve market share."

g01d4 writes "According to the LA Times, 'California's computer problems, which have already cost taxpayers hundreds of millions of dollars, have mounted as state officials cut short work on a $208-million DMV technology overhaul that is only half done. The state has spent $135 million total on the overhaul so far. The state's contractor, HP Enterprise Services, has received nearly $50 million of the money spent on the project. Botello said the company will not receive the remaining $26 million in its contract. ... Last week, the controller's office fired the contractor responsible for a $371-million upgrade to the state's payroll system, citing a trial run filled with mishaps. More than $254 million has already been spent.' It's hard not to feel like the Tokyo man in the street watching the latest round of Godzilla the state vs. Rodan the big contractor."

sciencehabit writes "Think potty training a child is hard? Try teaching a cow when and where to do its business. The bovines can defecate nine to 16 times daily, creating big hygiene problems on dairy and beef farms. So cueing the animals to go in the right place would be a big help for managing manure. But past techniques—including training cows to respond to mild electric shocks—have proven ineffective or impractical for wide use. To see if they could come up with a better potty prompt, scientists tested a series of stimuli on a dozen Holstein cows. The milkers stood in or walked through a footbath filled with water, for example, or had air or water sprayed on their feet. Alas, '[n]one of our tests reliably stimulated defecation,' the team reports."

sciencehabit writes "A new study shows that ant pupae—a stage between larvae and adult—can communicate via sound, and that this communication can be crucial to their survival. The young insects have a specialized spike along their abdomen that they stroke with one of their hind legs, similar to dragging the teeth of a comb along the edge of a table. This noise serves primarily as an emergency beacon, allowing the ants to shout for help when being threatened by a predator."

sciencehabit writes "The ancestor of all placental mammals—the diverse lineage that includes almost all species of mammals living today, including humans—was a tiny, furry-tailed creature that evolved shortly after the dinosaurs disappeared, a new study suggests. The hypothetical creature, not found in the fossil record but inferred from it, probably was a tree-climbing, insect-eating mammal that weighed between 6 and 245 grams—somewhere between a small shrew and a mid-sized rat. It was furry, had a long tail, gave birth to a single young, and had a complex brain with a large lobe for interpreting smells and a corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres of the brain. The period following the dinosaur die-offs could be considered a 'big bang' of mammalian diversification, with species representing as many as 10 major groups of placentals appearing within a 200,000-year interval."

tsamsoniw writes "While research companies including IDC and Gartner deemed HP the PC leader for Q4 2012, Canalys has a different perspective. The analyst firm has declared Apple the top PC vendor for the past quarter, thanks in part to the booming success of the iPad and the iPad mini. By Canalys's reckoning, Amazon, too, now beats out the likes of Acer and Asus as leading PC vendors, having shipped 4.6 million Kindles in Q4."

sciencehabit writes "Left to its own devices, a bubble will weaken and pop as the fluid sandwiched between two thin layers of soap succumbs to gravity and drains toward the floor. But when researchers trapped a bubble between two platinum electrodes and cranked up the voltage, the fluid reversed direction and actually flowed up, against the force of gravity. The newly strong and stable bubbles could live for hours, and even visibly change colors as their walls grew fatter. Because soap film is naturally only nanometers thick, this whimsical experiment could help scientists create more efficient labs-on-chips, the mazes of nanotunnels that can diagnose disease based on the movements of a miniscule drop of blood."

alphadogg writes "Microsoft's $2 billion loan to Dell is a sign that the software maker wants to influence hardware designs in a post-PC world while protecting itself from the growing influence of Linux-based operating systems in mobile devices and servers, according to analysts. As the world's third-largest PC maker, Dell is important to the success of Microsoft's server and PC software. Even though Microsoft's loan does not represent a big part of the total value of the transaction, the software maker does not throw around money lightly and its participation in the deal might be an attempt by the software maker to influence hardware designs in the post-PC world of touch laptops, tablets and smartphones, analysts said. It may also be an attempt to secure the partnership and to stop the PC maker from looking toward alternative operating systems like Linux, analysts said. Dell offers Linux servers and in late November introduced a thin and light XPS 13 laptop with a Linux-based Ubuntu OS, also code-named Project Sputnik. Major PC makers in recent months have also introduced laptops with Chrome OS." HP has released a statement in response to the deal which talks about how Dell "faces an extended period of uncertainty and transition that will not be good for its customers." Perhaps they're right; HP is certainly familiar with such a situation. However, it's likely Dell is simply hoping to avoid the same struggles HP has faced over the past several years.

Nerval's Lobster writes "Dell is going private again, as the result of a $24.4 billion deal involving private-equity investors and Microsoft. The deal will close before the end of the second quarter of Dell's fiscal 2014, according to Reuters. Dell founder and namesake Michael Dell, who owns roughly 14 percent of the company's common shares, will continue to lead the newly privatized venture as Chairman and Chief Executive Officer. He will contribute his existing shares to the new company, on top of a 'substantial' additional cash investment. As with other hardware manufacturers in the space, Dell faces the specter of a softening PC market. And while Dell has made significant efforts to penetrate other markets—including the launch of a private cloud architecture based on the open-source OpenStack—that weakness has affected its bottom line: for its fiscal 2013 third quarter, the company reported an 11 percent decrease in revenue from the previous year; while it enjoyed an increase in revenue from its servers and services businesses, revenue from its Consumer division dipped 23 percent. Its Large Enterprise, Small and Medium Business, and Public revenue also declined." Another take at the New York Times.

Nerval's Lobster writes "Hewlett-Packard is the latest PC manufacturer to jump into the Chromebook game, whipping the curtain back from a 14-inch device loaded with Google's Chrome OS. Powered by a dual-core Intel Celeron processor, and touting roughly 4.25 hours of battery life, the HP Pavilion Chromebook follows in the footsteps of other Chromebooks released by Acer and Samsung over the past few months. While these manufacturers continue to produce devices loaded with Windows, the growth of Chrome OS could spark some worry among Microsoft executives, who have become used to their hardware partners operating as Windows-only shops. But is Chrome OS a true threat to Windows, or just a way for manufacturers to gain some additional leverage in negotiating with Microsoft over licensing fees and other matters?"

sciencehabit writes "You don't have to be Superman to help those in need, but you might be more willing to do so if you get a taste of his powers. When subjects in a new study strapped on virtual reality helmets, half of them were given the ability to fly around a simulated city, while the others sat passively in helicopters. Some were allowed to merely explore the city from their aerial vantage points; others were told they needed to find a missing diabetic child and deliver his lifesaving insulin. Regardless of which task they performed, the subjects granted the superpower of flight were more likely to help a researcher pick up spilled pens after the experiment was. The results have researchers wondering if our brains might react to the memory of a virtual experience as though it had really happened. If so, we may be able to use virtual reality and gaming to effectively treat psychological disorders such as PTSD."
