sciencehabit writes "Despite long experience with the ways of the world, older people are especially vulnerable to fraud. According to the Federal Trade Commission, up to 80% of scam victims are over 65. One explanation may lie in a brain region that serves as a built-in crook detector. Called the anterior insula, this structure — which fires up in response to the face of an unsavory character — is less active in older people, possibly making them less cagey than younger folks, a new study finds."

sciencehabit writes about new estimates of Vega's age giving hope that any planets it might have are old enough to harbor life. From the article: "Shining just 25 light-years from Earth in the constellation Lyra, Vega is the fifth brightest star in the night sky. In 1983, astronomers discovered dust orbiting the star, suggesting it had a solar system, and Carl Sagan chose to make Vega the source of a SETI signal in his 1985 novel Contact. At the time, Vega was thought to be only about a couple hundred million years old, probably too young for any planets to have spawned life. Since then, however, estimates of Vega's age have increased to between 625 million and 850 million years old. So suitable planets have probably had sufficient time to develop primitive life." With improvements in telescopes allowing detection of the rough atmospheric composition of exoplanets on the way, this could be pretty exciting.

jamaicaplain writes "Reuters reports that 'Iran has suspended the death sentence for a computer programmer convicted on charges of running a pornographic website after he "repented for his actions," his lawyer was quoted as saying on Sunday. Saeed Malekpour, an Iranian citizen and Canadian resident, was arrested in 2008 while visiting relatives in Iran, according to Amnesty International. Although Iranian authorities accused him of running a pornography site, Amnesty has said the charges appear to stem from a software program created by Malekpour that was used without his knowledge to post pornographic images.'" It's not clear if he'll ever be released, however.

sciencehabit writes "People usually find out that they have cancer after developing symptoms or through a screening test such as a mammogram—signs that may appear only after the cancer has grown or spread so much that it can't be cured. But what if you could find out from a simple, highly accurate blood test that you had an incipient tumor? By sequencing the abnormal DNA that a tumor releases into a person's bloodstream, researchers are now one step closer to a universal cancer test. Although the technique is now only sensitive enough to detect advanced cancers, that may be a matter of money: As sequencing costs decrease, the developers of the method say the test could eventually pick up early tumors as well."

McGruber writes "CNBC is reporting that Meg Whitman claims HP was defrauded in its purchase of Autonomy. 'We believed there is a willful effort on the part of certain members of Autonomy management to mislead shareholders when Autonomy was a publicly traded company, and to mislead potential buyers including HP,' Whitman said. 'We stand by the forensic review that we've seen,' she added. I wish her the same level of success I had when I filed an eBay claim." Also covered at SlashBI, which names the write-down damage: $8.8 billion.

sciencehabit writes "Here's a twist: Scientists have designed a flexible, yarn-like artificial muscle that can also pack a punch. It can contract in 25 milliseconds—a fraction of the time it takes to blink an eye—and can generate power 85 times as great as a similarly sized human muscle. The new muscles are made of carbon nanotubes filled with paraffin wax that can twist or stretch in response to heat or electricity. When the temperature rises, the wax melts and forces the nanotubes to contract. Such artificial muscles, the researchers say, could power smart materials, sensors, robots, and even devices inside the human body."

Esther Schindler writes "The job of dealing with an under-performing employee doesn't end when the culprit is shown the door. Everyone focuses on security tasks, after you fire the idiot, such as changing passwords, but that's just one part of the To Do list. More important, in the long run, is the cleanup job that needs to be done after you fire the turkey, looking for the hidden messes and security flaws the ex-employee may have left behind. Otherwise, you'll still be cleaning up the problems six months later."

who_stole_my_kidneys writes in about how HP has gained a seat on the Linux Foundation's board of directors. "Snagging a first-class upgrade might empty out the contents of your wallet, but be glad you're not trying to buy your way to the Linux Foundation's top table. With a strategic investment of $500,000, Hewlett Packard has just become a platinum member of the body, alongside companies like Intel, Qualcomm and Samsung. In exchange for all that cash, HP gets a seat on the Foundation's board of directors and will have a say in how to advance the foundation's aims — and hopefully give Open webOS a gentle push, too."

A while ago you had the chance to ask Bruce Perens about how open source has changed in the past 15 years, what's happening now, and what's to come. Bruce has been busy traveling, but he's found some free time and sent in his answers. Read below to see what he has to say.

A reader writes with news that Automobile Magazine has named the all-electric Tesla Model S its Car of the Year. Quoting: "We weren't expecting much from the Tesla other than some interesting dinner conversation as we considered 'real' candidates like the Subaru BRZ and the Porsche Boxster. In fact, the Tesla blew them, and us, away. Actually, the Model S can blow away almost anything. 'It's the performance that won us over,' admits editor-in-chief Jean Jennings. 'The crazy speed builds silently and then pulls back the edges of your face. It had all of us endangering our licenses.' Our Model S was of Signature Performance spec, which means its AC induction motor puts out 416 hp and that it blasts to 60 mph in 4.3 seconds. ... You'll note that we haven't even discussed Tesla's raison d'etre, which is, in Musk's words, 'To accelerate the advent of electric cars.' That's another credit to the Model S's overall execution and seductive powers. 'The electric motor does not define this car,' says Nelson. But it is, at the end of the day, what makes this very good sport sedan an absolute game changer. The Model S's range, rated by the EPA at 265 miles with the largest battery, finally fits the American conception of driving."

sciencehabit writes with this excerpt from Science: "The dungeon is pitch black — until the dungeon master blazes a torch, confirming your worst fears. A Beholder monster lurches at you, its eyeballs wriggling on tentacular stems. As you prepare to wield your Vorpal sword, where do you focus your gaze: at the monster's head or at its tentacle eyes? Such a quandary from the role-playing game Dungeons & Dragons may seem like a meaningless trifle, but it holds within it the answer to a tricky scientific question: Do people focus their gaze on another person's eyes or on the center of the head? In fact, a father-son team has used D&D monsters to show that most people will look to another creature's eyes, even if they're not attached to a head."

alphadogg writes "The $100 million price differential between the Alcatel-Lucent and Cisco proposals to refresh California State University's 23-campus network revealed earlier this week was based on an identical number of switches and routers in various configurations. CSU allowed Network World to review spreadsheets calculating the eight-year total cost of ownership of each of the five bidders for the project. 'Everybody had to comply with this spreadsheet,' said CSU's director of cyberinfrastructure. 'Alcatel-Lucent won the project with a bid of $22 million. Cisco was the high bidder with a cost just under $123 million. Not only was Cisco's bid more than five-and-a-half times that of Alcatel-Lucent's, it was three times that of the next highest bidder: HP, at $41 million.'"

sciencehabit writes "A tonic of gut microbes may be the secret recipe for treating a common hospital scourge. Researchers have pinpointed the exact mix of microbes required to cure mice of chronic infection by Clostridium difficile. The hard-to-treat bacterium infects alomst 336,000 in the US each year and causes bloating, pain, & diarrhea. A similar bacterial cocktail may be able to replace the current controversial treatment involving the intake of a healthy person's fecal matter to restore the right balance of microbes in the gut."

sciencehabit writes "Science Magazine has crowned the winner of its annual 'Dance Your Ph.D.' contest. Scientists from around the globe are invited to submit videos of themselves interpreting their graduate theses in dance form. The results are often hilarious--and highly entertaining--and this year is no exception. This year's winner is Peter Liddicoat, a materials scientist at the University of Sydney in Australia, whose 'Evolution of nanostructural architecture in 7000 series aluminum alloys during strengthening by age-hardening and severe plastic deformation' is interpreted as a performance that employs juggling, clowning, and a big dance number—representing the crystal lattices that he studies with atomic microscopy."

walterbyrd writes "The Nano is currently powered by a 37 hp two-cylinder engine and lacks common safety features such as power steering, traction control and airbags. It was originally designed to compete in the Indian market against scooters and motorcycles. . . Along with added safety equipment, it's likely the car will get a larger, less polluting engine for export markets. Unfortunately, that means the price will increase, as well, possibly tripling by the time it goes on sale in the U.S.."

sciencehabit writes "Four young boys with a rare, fatal brain condition have made it through a dangerous ordeal. Scientists have safely transplanted human neural stem cells into their brains. Twelve months after the surgeries, the boys have more myelin—a fatty insulating protein that coats nerve fibers and speeds up electric signals between neurons—and show improved brain function, a new study in Science Translational Medicine reports. The preliminary trial paves the way for future research into potential stem cell treatments for the disorder, which overlaps with more common diseases such as Parkinson's disease and multiple sclerosis."

angry tapir writes "Lenovo has taken the crown from Hewlett-Packard to become the world's top seller of PCs, research firm Gartner said in a study released this week. Lenovo took the top spot during a quarter in which PC shipments dropped overall due to a weak economy and pressure from mobile devices. Of the top four PC vendors, only Lenovo was able to grow its shipments. Its PC sales increased by almost 10 percent to 13.77 million units, giving it 15.7 percent of the market, Gartner said." Not so fast, says analysis firm IDC. They say that HP is still in the lead but Lenovo is very close.

dcblogs writes "Hewlett-Packard CEO Meg Whitman told financial analysts today that it will take until 2016 to turn the company around. Surprisingly, Whitman put some of the blame for the company's woes on its IT systems, which she said have hurt its internal operations. To fix its IT problems, Whitman said the company is adopting Salesforce and HR system Workday. The company also plans to cut product lines. It said it makes 2,100 different laser printers alone; it wants to reduce that by half. 'In every business we're going to benefit from focusing on a smaller number of offerings that we can invest in and really make matter,' said Whitman."

New submitter clam666 writes "White House sources partly confirmed that U.S. government computers — reportedly including systems used by the military for nuclear commands — were breached by Chinese hackers. From the article: 'The attempted hack used 'spear phishing,' in which an attacker sends an email to a specific target that uses familiar phrases in hopes that the recipient will follow links or download attachments that unleash the hacker's malware. None of the White House's secure, classified computer systems were affected, said the official, who reached out to POLITICO after the Free Beacon story appeared — without having been asked for comment. Nor had there been any attempted breach of a classified system, according to the official.'"
