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."

sciencehabit writes "Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew what it was made of or exactly how it worked. Now a team of researchers has found a single iron atom at the head of the spike, a discovery that suggests phages enter bacteria in a different way than surmised (abstract)."

sciencehabit writes "New research suggests that the upper classes are more likely to behave dishonorably than those lower on the economic spectrum. The rich are more likely to cheat, steal, and even disobey traffic laws than those with less money and power (abstract). Curiously, in one experiment, Prius drivers also behaved badly, regardless of their wealth."

sciencehabit writes "Men typically produce working sperm as long as they live, but most textbooks say female mammals are born with all the egg cells, or oocytes, they will ever have. Since 2004, however, reproductive biologist Jonathan Tilly of Massachusetts General Hospital in Boston has challenged that conventional wisdom, arguing that in mice—and perhaps also in humans—there must be an ongoing source of new eggs. Today, Tilly and his colleagues report isolating rare cells in ovarian tissue from adult women that can grow in lab dishes and form immature oocytes. The potential egg stem cells could help scientists devise new ways to help rescue the fertility of women who have to undergo cancer treatments or who suffer from premature menopause."

sciencehabit writes "The CERN particle physics laboratory in Geneva has confirmed Wednesday's report that a loose fiber-optic cable may be behind measurements that seemed to show neutrinos outpacing the speed of light. But the lab also says another glitch could have caused the experiment to underestimate the particles' speed. The other effect concerns an oscillator that gives its readings time stamps synchronized to GPS signals. Researchers think correcting for an error in this device would actually increase the anomaly in neutrino velocity, making the particles even speedier than the earlier measurements seemed to show."

smolloy writes "It would appear that the hotly debated faster-than-light neutrino observation at CERN is the result of a fault in the connection between a GPS unit and a computer. This connection was used to correct for time delays in the neutrino flight, and after fixing the correction the researchers have found that the time discrepancy appears to have vanished."

kodiaktau writes "Google is working to deliver a heads-up display allowing users access to email, maps and other tools through a wearable interface. According to the NY Times' sources, the device will be available later this year, and sell for prices comparable to smartphones. 'The people familiar with the Google glasses said they would be Android-based, and will include a small screen that will sit a few inches from someone’s eye. They will also have a 3G or 4G data connection and a number of sensors including motion and GPS. ... The glasses will have a low-resolution built-in camera that will be able to monitor the world in real time and overlay information about locations, surrounding buildings and friends who might be nearby, according to the Google employees. The glasses are not designed to be worn constantly — although Google expects some of the nerdiest users will wear them a lot — but will be more like smartphones, used when needed.'"

New submitter egparedes points out a post dissecting webOS and highlighting the things it did right, in the hopes that developers for other mobile operating systems will use them as inspiration. Quoting: "webOS isn't quite dead yet. It's just being open-sourced, which, when it happens to commercial software, often turns out to be the digital equivalent of being reanimated as a walking corpse in a George Romero movie. ... Of course, it's not assured that this is the end of webOS. Maybe open-sourcing it will be the best thing that ever happened to webOS. But maybe it just means that HP doesn't care anymore, and that webOS won't receive much attention anymore. This would be unfortunate, because webOS is one of the few current mobile operating systems that are actually a joy to use. It's been hurt by HP's incompetent management, rather than any egregious faults of its own. The least we can do now is to keep its best ideas alive, even if webOS itself won't make it."

New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

swandives writes "WebOS could be an important player in the long run as an open-source mobile OS, because Android could become closed source with Google's purchase of Motorola Mobility, Hewlett-Packard CEO Meg Whitman said during a speech at the HP Global Partner conference in Las Vegas. It may take up to four years for the complete impact of webOS to be felt, Whitman said. HP has said it would release WebOS — originally developed by Palm for phones and tablets — to the open-source community. The company bought Palm in 2010 but late last year announced it will not make devices that use the software."

jfruh writes "HP reversed its decision to spin off its PC business, but it's still left with the question of how to make money in a commodity business selling standard-issue machines manufactured overseas. One idea they're contemplating: improved customer service. If you buy an HP 'Elite' PC and have problems, you won't have to phone into a tech support call center where an entry-level drone reads off a script and tells you to reboot the machine; you'll have access to a specific support tech who will work with you as long as you own the computer."
