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."

Rick Zeman writes "According to a headline article in the New York Times, they admit to being hacked by the Chinese, and covers the efforts of Mandiant to investigate, and then to eradicate their custom Advanced Persistent Threats (APT). This was alleged to be in reaction to an article which details the sleazy business dealings of the family of Wen Jiabao, China's newest Prime Minister. China's Ministry of National Defense said in denial, 'Chinese laws prohibit any action including hacking that damages Internet security.'" Update: 01/31 15:00 GMT by T : The Times used Symanetic's suite of malware protection software; Symantec has issued a statement that could be taken as slightly snippy about its role in (not) preventing the spyware from taking hold.

sciencehabit writes "A quick visit to Monty Python's Ministry of Silly Walks shows just how many ways humans (or at least British comedians) can think of to travel from point A to point B. So why don't we high kick our way to the bus stop or skip to the grocery store? New research suggests that there may be a deep biomechanical reason governing the gaits we choose in different situations. In short, people consistently choose to walk when they need to travel slower than 2 m/s to reach their goal in the given time; when they needed to move about 3 m/s or faster, they ran. But in between—in 'the twilight zone between walking and running'—people tended to mix the two gaits, minimizing their energy expenditure. The findings could help scientists design better prosthetic limbs and even build more human-like robots"

sciencehabit writes "Researchers have identified three genetic mutations that appear to have helped humans survive in the frigid climate of Siberia over the last 25,000 years. One helps the body's fat stores directly produce heat rather than producing chemical energy for muscle movements or brain functions, a process called 'nonshivering thermogenesis.' Another is involved in the contraction of smooth muscle, key to shivering and the constriction of blood vessels to avoid heat loss. And the third is implicated in the metabolism of fats, especially those in meat and dairy products—a staple of the fat-laden diets of Arctic peoples."

sciencehabit writes "Each year, hundreds of millions of metric tons of dust, water, and humanmade pollutants make their way into the atmosphere, often traveling between continents on jet streams. Now a new study confirms that some microbes make the trip with them, seeding the skies with billions of bacteria and other organisms—and potentially affecting the weather. What's more, some of these high-flying organisms may actually be able to feed while traveling through the clouds, forming an active ecosystem high above the surface of the Earth."

rtfa-troll writes "The Register tells us that Microsoft has begun squabbling with PC manufacturers over the reasons behind the failure of Windows 8. Microsoft is 'frustrated with major OEMs who didn't build nearly enough touch systems.' PC manufacturers have hit back, saying that they 'would have been saddled with the costs of a huge pile of unsold units,' claiming that customers actually avoided higher-end touch products which were available and instead bought lower-end, cheaper laptops while 'Microsoft is not blaming itself for' the failure of its own touch device, the Surface RT. The PC manufacturers' claims that touch is the problem seem to be backed by reviews, and some educational rants from users and opinions from user interface design experts. However, Microsoft sees this differently. Microsoft is planning to strike back at the PC vendors in February with Surface Pro; with a shorter battery life and much heavier than a normal tablet, this is being seen as a direct competitor to traditional laptops. By using its desktop operating system franchise as a lever, Microsoft will be able to enter the lower-specification end of the laptop market with a cost advantage which make make life difficult for former partners such as HP and Dell. We've discussed previously how some PC manufactures such as Dell have failed in generational change whilst others have diversified to survive market changes; Samsung with Android and the (still) bestselling Chromebook. ASUS with their successful Nexus tablets. We also discussed the ergonomic problems which are claimed to make touch screens unsuitable for PC use."

sciencehabit writes with this excerpt from Science magazine's colorful synopsis of a paywalled article at Current Biology "A day in the life of a male dung beetle goes something like this: Fly to a heap of dung, sculpt a clump of it into a large ball, then roll the ball away from the pile as fast as possible. However, it turns out that the beetles, who work at night, need some sort of compass to prevent them from rolling around in circles. New research suggests that the insects use starlight to guide their way. Birds, seals, and humans also use starlight to navigate, but this is the first time it's been shown in an insect." Also on the topic of How Animals Get Around Without GPS, new research has considerably heightened scientists understanding of birds' sensitivity to magnetic fields. For homing pigeons at least, this ability seems to be tied to a cluster of just 53 neurons (original paper, also behind a paywall).

sciencehabit writes "A purported conflict between the century-old theory of classical electrodynamics and Einstein's theory of special relativity doesn't exist, a chorus of physicists says. Last April, an electrical engineer claimed that the equation that determines the force exerted on an electrically charged particle by electric and magnetic fields — the Lorentz force law — clashes with relativity, the theory that centers on how observers moving at a constant speed relative to one another will view the same events. To prove it, he concocted a simple 'thought experiment' in which the Lorentz force law seemed to lead to a paradox. Now, four physicists independently say that they have resolved the paradox."

Jeremiah Cornelius writes "Blogger Adam Howard at Port3000 has a post about Google's exposure of thousands of publicly accessible printers. 'A quick, well crafted Google search returns "About 86,800 results" for publicly accessible HP printers.' He continues, 'There's something interesting about being able to print to a random location around the world, with no idea of the consequence.' He also warns about these printers as a possible beachhead for deeper network intrusion and exploitation. With many of the HP printers in question containing a web listener and a highly vulnerable and unpatched JVM, I agree that this is not an exotic idea. In the meanwhile? I have an important memo for all Starbucks employees."

sciencehabit writes "In a new study, researchers find that a single number that describes the complexity of feather patterns on bird chests, a parameter called the fractal dimension, is linked to whether a bird has a strong immune system or is malnourished. When scientists restricted the food of red-legged partridges, the patterns on their chests had a lower fractal dimension than those sported by their well-fed colleagues. The food-restricted birds, on average, weighed 13% less than their well-fed colleagues and had weaker immune systems, which makes fractal dimension an easily recognizable sign of a potential mate's health and vitality, the researchers contend."

sciencehabit writes "Male scientists — especially at the upper echelons of the profession — are far more likely than women to commit misconduct. That's the bottom line of a new analysis by three microbiologists of wrongdoing in the life sciences in the United States. Ferric Fang of the University of Washington, Seattle; Joan Bennett of Rutgers University; and Arturo Casadevall of Albert Einstein College of Medicine combed through misconduct reports on 228 people released by the U.S. Office of Research Integrity (ORI) over the last 19 years. They then compared the gender balance — or imbalance, in this case — against the mix of male and female senior scientists and trainees to gauge whether misconduct was more prevalent among men. A remarkable 88% of faculty members who committed misconduct were men, or 63 out of 72 individuals. The number of women in that group was one-third of what one would expect based on female representation in the life sciences."

itwbennett writes "As previously reported on Slashdot, in November of last year, the city of Munich reported savings of over €10 million from its switch to Linux. Microsoft subsequently commissioned a study (conducted by HP) that found that, in fact, 'Munich would have saved €43.7 million if it had stuck with Microsoft.' Now, Microsoft has said it won't release the study, saying that '[it] was commissioned by Microsoft to HP Consulting for internal purposes only.'"

sciencehabit writes with this excerpt from Science Magazine "Last November, astronomer David Turner made headlines by claiming that one of the sky's best known objects—the North Star, Polaris—was actually 111 light-years closer than thought. If true, the finding might have forced researchers to rethink how they calculate distances in the cosmos as well as what they know about some aspects of stellar physics. But a new study argues that distance measurements of the familiar star made some 2 decades ago by the European Space Agency's venerable Hipparcos satellite are still spot on."

sciencehabit writes "Scientists have found that, when it comes to mental recall, people are far more likely to remember the text of idle chitchat on social media platforms like Facebook than the carefully crafted sentences of books. The team gathered 200 Facebook posts from the accounts of undergraduate research assistants, such as 'Bc sometimes it makes me wonder' and 'The library is a place to study, not to talk on your phone.' They also randomly selected 200 sentences from recently published books, gathered from free text on Amazon.com. Sentences included, 'Underneath the mass of facial hair beamed a large smile,' and 'Even honor had its limits.' Facebook posts were one-and-a-half times as memorable as the book sentences (abstract). The researchers speculate that effortless chatter is better than well-crafted sentences at tapping into our minds' basic language capacities — because human brains evolved to prioritize and remember unfiltered information from social interaction."

sciencehabit writes "To humans, all fire ants may look alike. But the tiny, red, stinging bugs known as Solenopsis invicta have two types of social organization, and these factions are as recognizable to the ants as rival football teams are to us. Researchers once thought that the groups' distinct physiological and behavioral profiles stemmed from a variant in a single gene. Now, a new study (abstract) provides the first evidence that the gene in question is bound up in a bundle of some 600 other genes, versions of which are all inherited together. This 'supergene' takes up a large chunk of what may be the first known social chromosome, analogous to the chromosomes that determine sex in humans."
