An anonymous reader writes with this dose of nice news (untranslated from the PR-ese) on the Linux-in-business front: "Mark Shuttleworth has announced at the OpenStack conference that Canonical has received a ringing endorsement from HP in the form of certification for Ubuntu 12.04 LTS on the ProLiant server systems. Responding to customer demand, HP has decided to officially support the popular flavor of Linux giving sysadmins another flexible software option to leverage their current and future hardware."

sciencehabit writes "Spinal cord injuries cause paralysis because they sever crucial communication links between the brain and the muscles that move limbs. A new study with monkeys demonstrates a way to re-establish those connections. By implanting electrodes in a movement control center in the brain and wiring them up to electrodes attached to muscles in the arm, researchers restored movement to monkeys with a temporarily paralyzed hand. The work is the latest promising development in the burgeoning field of neuroprosthetics."

sciencehabit writes "Waking up from surgery can be disorienting. One minute you're in an operating room counting backwards from 10, the next you're in the recovery ward sans appendix, tonsils, or wisdom teeth. And unlike getting up from a good night's sleep, where you know that you've been out for hours, waking from anesthesia feels like hardly any time has passed. Now, thanks to the humble honeybee, scientists are starting to understand this sense of time loss. New research shows that general anesthetics disrupt the social insect's circadian rhythm, or internal clock, delaying the onset of timed behaviors such as foraging and mucking up their sense of direction."

Esther Schindler writes "An MIT professor explains why "simple" ideas require hard science and how a gemstone might be the key to an optical network. As the story begins: 'For years, the dream of an all-optical network has lain somewhere between Star Wars and a paper cup and a string. Recent successful work on the creation of an optical diode is a virtual case study in both the physics and materials sciences challenges of trying to develop all-optical networks. It is also a significant step towards their final realization.' One answer may be... garnet. Yes, the January birthstone. 'The material that Ross and others in her field use is a synthetic, lab-grown garnet film. Similar to the natural mineral, often used as a gemstone, it is transparent in the infrared part of the spectrum. This makes synthetic garnet ideal for optical communications systems, which use the near infrared. Unlike natural garnet, it's also magnetic. ... While it works, it's too big and too labor intensive for use as a commercial integrated chip. For that, you need to grow garnet on silicon. The challenge that Ross's group overcame is that garnet doesn't grow on silicon.'"

sciencehabit writes in with a link about a group of students who have come up with an interesting idea about how to fill potholes. "Non-Newtonian fluids are the stars of high school science demonstrations. In one example, an ooey-gooey batter made from corn starch and water oozes like a liquid when moved slowly. But punch it, or run across a giant puddle of it, and it becomes stiff like a solid. Now, a group of college students has figured out a new use for the strange stuff: filler for potholes."

wiredmikey writes "HP has warned of a security vulnerability associated with its ProCurve 5400 zl switches that contain compact flash cards that the company says may be infected with malware. The company warned that using one of the infected compact flash cards in a computer could result in the system being compromised. According to HP, the potential threat exists on HP 5400 zl series switches purchased after April 30, 2011 with certain serial numbers listed in the security advisory. This issue once again brings attention to the security of the electronics supply chain, which has been a hot topic as of late."

sciencehabit writes with good news involving cancer research. From the article: "Chemotherapy drugs are like a shotgun. Even though doctors are just aiming for tumors, the compounds hit a variety of other places in the body, leading to side effects like bone marrow damage and hair loss. To improve their aim, researchers have tried to package these drugs inside tiny hollow nano-sized containers that can be directed toward tumors and bypass healthy tissues. But the size, shape, and makeup of these 'nanoparticles' can drastically affect where and when they are taken up. Now, scientists have surveyed the landscape of some 100 different nanoparticle formulations and shown that when a conventional chemotherapeutic drug is packaged inside the best of these nanoparticles, it proves considerably more effective at fighting prostate cancer (summary; article paywalled) in animals than the drug alone."

sciencehabit writes "Paleontologists have unearthed fossils of the largest feathered creature yet known, a 1.4-metric ton dinosaur that was an early cousin of Tyrannosaurus rex. The long, filament-like feathers preserved with three relatively complete skeletons of the newly described species provide direct evidence of extensively feathered gigantic dinosaurs. The discovery is controversial—and in some scientific circles, largely unexpected."

A fight over posting calorie counts for popcorn is just one example of the clash between the White House and the agency charged with protecting public health. Dr. Margaret A. Hamburg, the F.D.A. commissioner, was forced to scrap plans to have calorie counts posted for foods served in movie theaters and on airplanes after a phone call from the White House deputy chief of staff in 2010. From the article: "White House officials describe their disagreements with the F.D.A. as part of the normal, constructive give-and-take over policy that has never undermined the agency’s mission. 'Under President Obama’s leadership, the Food and Drug Administration has new authority and resources to help stop kids from smoking, protect our food supply and approve more affordable prescription drugs,' said the White House press secretary, Jay Carney. The administration also views the agency’s hostility to its oversight as hopelessly naïve, given a 24-hour news cycle and a ferocious political environment that punishes any misstep. 'They want a world that doesn’t exist anymore,' an administration official said."

sciencehabit writes "The massive oil spill that inundated the Gulf of Mexico in the spring and summer of 2010 severely damaged deep-sea corals more than 11 kilometers from the well site, a sea-floor survey conducted within weeks of the spill reveals. At one site, which hadn't been visited before but had been right in the path of a submerged 100-meter-thick oil plume from the spill, researchers found a variety of corals — most of them belonging to a type of colonial coral commonly known as sea fans — on a 10-meter-by-12-meter outcrop of rock. Many of the corals were partially or completely covered with a brown, fluffy substance that one team member variously calls 'frothy gunk,' 'goop,' and 'snot.'"

sciencehabit writes, quoting an article in Science: "A single drug can shrink or cure human breast, ovary, colon, bladder, brain, liver, and prostate tumors that have been transplanted into mice, researchers have found. The treatment, an antibody that blocks a 'do not eat' signal normally displayed on tumor cells, coaxes the immune system to destroy the cancer cells." The abstract and full paper are freely available. It seems fairly promising: "In mice given human bladder cancer tumors, for example, 10 of 10 untreated mice had cancer that spread to their lymph nodes. Only one of 10 mice treated with anti-CD47 had a lymph node with signs of cancer. Moreover, the implanted tumor often got smaller after treatment — colon cancers transplanted into the mice shrank to less than one-third of their original size, on average. And in five mice with breast cancer tumors, anti-CD47 eliminated all signs of the cancer cells, and the animals remained cancer-free 4 months after the treatment stopped."

sciencehabit writes "A new analysis of isotopes found in lunar minerals challenges the prevailing view of how Earth's nearest neighbor formed. Geochemists looked at titanium isotopes in 24 separate samples of lunar rock and soil, and found that the moon's proportion was effectively the same as Earth's and different from elsewhere in the solar system. This contradicts the so-called Giant Impact Hypothesis, which posits that Earth collided with a hypothetical, Mars-sized planet called Theia early in its existence, and the resulting smash-up produced a disc of magma orbiting our planet that later coalesced to form the moon."

sciencehabit writes "Researchers have long hypothesized that objects weigh less at Earth's equator because the planet's spin and shape lessen gravity's pull there versus at the poles. Satellite accelerometers have confirmed this, but a digital scale manufacturer decided to test things the old-fashioned way. Enter the Kern garden gnome. When placed on a scale at the South Pole, the intrepid ornament weighed 309.82 grams versus 307.86 grams at the equator, a difference of 0.6%."

itwbennett writes "Apotheker wanted to sell off HP's PC division, Whitman vowed not to, and now HP is combining the PC division with the printer division in an effort to cut costs, unnamed sources told the All Things D blog. Given that both divisions reported declining sales last quarter, is HP hoping that two wrongs make a right?"

sciencehabit writes "Michael Snyder has taken 'know thyself' to the next level. Over a 14-month period, the molecular geneticist analyzed his blood 20 different times to pluck out a wide variety of biochemical data depicting the status of his body's immune system, metabolism, and gene activity. In yesterday's issue of Cell (abstract), Snyder and a team of 40 other researchers present the results of this extraordinarily detailed look at his body, which they call an integrative personal omics profile (iPOP) because it combines cutting-edge scientific fields such as genomics (study of one's DNA), metabolomics (study of metabolism), and proteomics (study of proteins). Instead of seeing a snapshot of the body taken during the typical visit to a doctor's office, iPOP effectively offers an IMAX movie, which in Snyder's case had the added drama of charting his response to two viral infections and the emergence of type 2 diabetes."

sciencehabit writes "Offer a male fruit fly a choice between food soaked in alcohol and its nonalcoholic equivalent, and his decision will depend on whether he's mated recently or been rejected by a female. Flies that have been given the cold shoulder are more likely to go for the booze, researchers have found. It's the first discovery, in fruit flies, of a social interaction that influences future behavior."

Rick Zeman writes "According to the New York Times, it's the end of the road for the printed Encyclopedia Brittanica, saying, '...in recent years, print reference books have been almost completely wiped out by the Internet and its vast spread of resources, particularly Wikipedia, which in 11 years has helped replace the authority of experts with the wisdom of the crowds.' The last print edition will be the 32-volume 2010 edition."

Esther Schindler writes "Many of us geeks prefer to work at home without distractions, but a lot of bosses still believe that if they don't see you, you must be lolling about, eating bon-bons and playing Angry Birds. 'There may be many reasons a manager is distrustful of telecommuting but the phenomenon of what Albiero calls "presentism"—that is, only trusting and rewarding the folks you see at their computer is a major factor.' So it may be of some use to read through the research compiled by Diann Daniel that says telecommuting creates happier and more productive employees (which naturally include fewer distractions and better work-life balance), and an accompanying infographic showing the environmental benefits from reduced commuting. She follows it up with suggestions on how managers can mentor and support teleworkers. Some of this is general advice, but some of the tips are more specific: 'It may seem like a lot more work—all this up-front addressing of communication issues that happen far more naturally in the office—but the upside is increased efficiency. Albiero sees this especially in the area of meetings. He speaks of one client who has now instituted a meeting format that is structured to allow for the first five minutes of all meetings to be "small-talk minutes." Thus, everyone knows they needn't call in for those minutes unless they want to join."

sciencehabit writes "The big bang created a lot of matter—along with the same amount of antimatter, which wiped out everything and brought the universe to an untimely end. That's what accepted theoretical physics tell us—though things clearly didn't work out that way. Now, results from a U.S. particle smasher are providing new evidence for a subtle difference in the properties of matter and antimatter that may explain how the early universe survived."

alphadogg writes "Hewlett-Packard has cut 275 jobs in its webOS group, as part of its strategy to turn the operating system over to the open-source community, according to IDG News Service. HP said last year that it would stop making devices that use the operating system which was developed by Palm for phones and tablets, and later decided to release the software under the Apache License 2.0. As webOS continues the transition to open-source software, HP no longer needs many of the engineering and other related positions that it required before, the company said in a statement. 'This creates a smaller and more nimble team that is well-equipped to deliver an open source webOS and sustain HP's commitment to the software over the long term,' it added."
