A Black Hole's Spinning Heart of Darkness 121

sciencehabit writes "Like all invisible things that are only partly understood, black holes evoke a sense of mystery. Astronomers know that the tremendous gravitational pull of a black hole sucks matter in, and that the material falling in causes powerful jets of particles to shoot out of the hole at nearly the speed of light. But how exactly this phenomenon occurs remains a matter of conjecture, because astronomers have never quite managed to observe the details – until now. Astrophysicists have taken the closest look to date at the region where matter swirls around a black hole. By measuring the size of the base of a jet shooting out of the supermassive black hole at the center of the M87 galaxy (abstract), the researchers conclude that the black hole must be spinning and that the material orbiting must also be swirling in the same direction. Some of the material from this orbiting 'accretion disk' is also falling into the black hole, like water swirling down a drain."

HP Releases Open webOS 1.0 51

An anonymous reader writes "Hewlett-Packard has announced the release Open webOS version 1.0: 'We now have an OpenEmbedded build that allows a full webOS experience running inside an OE emulator. We have added core applications — email & browser — while continuing to support the desktop build environment. The 1.0 release also brings support for Enyo2. You can now take apps built on one of the best cross-platform JavaScript frameworks and easily run these same apps on Open webOS or other platforms. In the past 9 months, we have delivered over 75 Open webOS components. This totals over 450,000 lines of code. ... The source code for Open webOS can be found in Open webOS repositories on GitHub. Combining today's components with those from the previous releases, Open webOS can now be ported to new devices.' HP also reaffirmed plans to continue work on Open webOS, and to bring support for Qt5, WebKit2, open source media components, and more."

Patent Troll Goes After Facebook, Apple, Microsoft, Yahoo, IBM, Others 171

zaba writes "A company named PersonalWeb Technologies has decided to sue a host of heavy players in the tech industry, including Apple, Facebook, IBM, Microsoft and Yahoo! for patents it holds related to data processing. They have a previous suit against other big names like Amazon, Google and HP. Anyone care to guess where the company is based or where the suits were filed?" The company is also targeting GitHub, but seems to have accidentally sued Rackspace — GitHub's host — instead. Rackspace has responded, saying, "It’s apparent that the people filing the suit don’t understand the technology or the products enough to realize that Rackspace Cloud Servers and GitHub are completely different products from different companies."

Rewiring the Autistic Brain 139

sciencehabit writes "Signs of autism — such as impaired social skills and repetitive, ritualistic movements — usually begin to appear when a child is about 18 months old. Autism is thought to result from miswired connections in the developing brain, and many experts believe that therapies must begin during a 'critical window,' before the faulty circuits become fixed in place. But a new study (abstract) shows that at least one malfunctioning circuit can be repaired after that window closes, holding out hope that in some forms of autism, abnormal circuits in the brain can be corrected even after their development is complete."

Study: Online Social Influence Has the Strongest Effect On Voting Behavior 114

sciencehabit writes "Brace yourself for a tidal wave of Facebook campaigning before November's U.S. presidential election. A study of 61 million Facebook users finds that using online social networks to urge people to vote has a much stronger effect on their voting behavior than spamming them with information via television ads or phone calls."

Star Trek Tech That Exists Today 207

Esther Schindler writes "When Star Trek hit the air waves, talking computers were just a pipe dream. While teleportation remains elusive, several once-fictional technologies are changing the way people live and work. Here are some ways in which we're approaching the gizmos that Star Trek demonstrated. Speech recognition? Check. Holodeck? Sort of. Replicator? Workin' on it."

Intel Confirms Decline of Server Giants 152

An anonymous reader writes "A Wired article discusses the relative decline of Dell, HP, and IBM in the server market over the past few years. Whereas those three companies once provided 75% of Intel's server chip revenue, those revenues are now split between the big three and five other companies as well. Google is fifth on the list. 'It's the big web players that are moving away from the HPs and the Dells, and most of these same companies offer large "cloud" services that let other businesses run their operations without purchasing servers in the first place. To be sure, as the market shifts, HP, Dell, and IBM are working to reinvent themselves. Dell, for instance, launched a new business unit dedicated to building custom gear for the big web players — Dell Data Center Services — and all these outfits are now offering their own cloud services. But the tide is against them.'"

Drinking Too Much? Blame Your Glass 115

sciencehabit writes "Before you down that pint, check the shape of your glass—you might be drinking more beer than you realize. According to a new study of British beer drinkers, an optical illusion caused by the shape of a curved glass can dramatically increase the speed at which we swill. The researchers recruited 160 Brits, and asked them to watch a nature documentary while they drank beer from straight or curved glasses. The group drinking a full glass of lager out of curved flute glasses drank significantly faster than the other group--possibly because the curved glasses impaired their ability to pace themselves while drinking."

HP Launches Beta of Open webOS 56

puddingebola writes "HP done gone and released the open source version of webOS. From the article: 'Gone are the days of HP's TouchPad and Palm ambitions, but HP is moving ahead with its plans to make webOS, its beleaguered mobile operating system, live on as open-source supported platform. Today it's launching the beta release... The release will have 54 components available as open source, the blog says, some 450,000 lines of code under the Apache 2.0 license.'" There are two flavors: an OpenEmbedded based version for targeting mobile device (kudos there!), and a desktop build which runs Luna as an application on the desktop (how long until someone writes a rootless version?).

Calorie Restriction May Not Extend Lifespan 251

sciencehabit writes "Slash your food intake and you can live dramatically longer — at least if you're a mouse or a nematode. But a major study designed to determine whether this regimen, known as caloric restriction, works in primates suggests that it improves monkeys' health but doesn't extend their lives. Researchers not involved with the new paper say the results are still encouraging. Although the monkeys didn't evince an increase in life span, both studies show a major improvement in 'health span,' or the amount of time before age-related diseases set in. 'I certainly wouldn't give up on calorie restriction as a health promoter' based on these findings, says molecular biologist Leonard Guarente of the Massachusetts Institute of Technology in Cambridge."

The History of the Floppy Disk 204

Esther Schindler writes "Ready for a nostalgic trip into the wayback? We had floppy disks long before we had CDs, DVDs, or USB thumb-drives. Here's the evolution of the portable media that changed everything about personal computing. 'The 8-inch drive began to show up in 1971. Since they enabled developers and users to stop using the dreaded paper tape (which were easy to fold, spindle, and mutilate, not to mention to pirate) and the loathed IBM 5081 punch card. Everyone who had ever twisted a some tape or—the horror!—dropped a deck of Hollerith cards was happy to adopt 8-inch drives. Besides, the early single-sided 8-inch floppy could hold the data of up to 3,000 punch cards, or 80K to you.'"

Lexmark To Exit Inkjet Printer Market 228

Barence writes "Lexmark has announced it will stop making inkjet printers and cut 1,700 jobs as part of a cost-cutting restructuring move. Lexmark will stop all inkjet development worldwide by 2013, and close its Philippines-based inkjet supplies manufacturing plant by 2015. This will provide annual savings of $85 million, rising to $95 million by 2015. The total restructuring cost before tax is expected to be $160 million. The company is also looking into the possible sale of its inkjet-related technology." I know there are some purposes for which inkjets are good (modern home photo printing can be insanely good, and we've featured a lot of cool projects which use inkjets to print sensors, solar cells, antennae, and more), but I get just a little queasy whenever I see an inkjet printer purchased by an innocent friend or family member who doesn't realize quite how much it will end up costing them in the long run.

PC Makers In Desperate Need of a Reboot 622

nmpost writes in with a story about how hard it is to be a successful PC company in today's world. "Hewlett-Packard Co. used to be known as a place where innovative thinkers flocked to work on great ideas that opened new frontiers in technology. These days, HP is looking behind the times. Coming off a five-year stretch of miscalculations, HP is in such desperate need of a reboot that many investors have written off its chances of a comeback. Consider this: Since Apple Inc. shifted the direction of computing with the release of the iPhone in June 2007, HP's market value has plunged by 60 percent to $35 billion. During that time, HP has spent more than $40 billion on dozens of acquisitions that have largely turned out to be duds so far. HP might have been unchallenged for the ignominious title as technology's most troubled company if not for one its biggest rivals, Dell Inc. Like HP, Dell missed the trends that have turned selling PCs into one of technology's least profitable and slowest growing niches. As a result, Dell's market value has also plummeted by 60 percent, to about $20 billion, since the iPhone's release."

Logitech Releases Washable Keyboard 205

MrSeb writes "Logitech has released its first washable keyboard. We're not just talking about 'splash proof' either — you can take the K310, immerse it in up to 30cm of water (12in), and give it a good scrub. The only limitation is you can only use standard washing up liquid — oh, and Logitech says you should try to keep the USB connector out of the water, too. Once you've washed the keyboard, simply leave it to dry. The user guide says it takes eight hours to air dry, and that you shouldn't use a hair dryer. There are actually drainage holes on the backside of the K310, to help speed things along. This isn't the first washable keyboard — HP and Kensington have both had models on the market for a while — but the K310 does seem to be the first reasonably attractive, consumer-oriented washable keyboard. It goes on sale at the end of the month for $40."

Why Cell Phone Bans Don't Work 335

sciencehabit writes "You can take the driver away from the cell phone, but you can't take the risky behavior away from the driver. That's the conclusion of a new study, which finds that people who talk on their phones while driving may already be unsafe drivers who are nearly as prone to crash with or without the device. The findings may explain why laws banning cell phone use in motor vehicles have had little impact on accident rates."

Do Antibiotics Contribute To Obesity? 252

sciencehabit writes "Farmers have long used antibiotics to make cows, pigs, and turkeys gain weight faster. Now, scientists claim that receiving antibiotics early in life may also make children grow fat (abstract).

Cats Not Linked To Brain Cancer After All 102

sciencehabit writes with good news for cat owners everywhere. From the article: "Last year, cat owners got a scare when a team of French researchers reported a possible link between felines and brain cancer. Cat feces can harbor a single-celled parasite called Toxoplasma gondii, and the scientists found that nations with higher rates of human T. gondii infection also have higher incidences of brain cancer. A new study challenges those findings [paywalled after the first view]. Scientists examining a cohort of more than 600,000 British women found that cat owners were no more likely to develop brain cancer than their cat-free counterparts, despite their presumably greater risk of exposure to T. gondii." The study in question mostly just found that T. gondii infection rates aren't correlated with cat ownership after all, but there's still no word on whether our friend the parasite causes cancer or not.

HP Hires Ex-Nokia Exec, Spins Off WebOS, Reportedly Returning To Tablets 128

judgecorp writes "Hewlett-Packard is returning to tablets with a new unit that aims to make consumer devices under the leadership of former Nokia executive Alberto Torres." This particular Ex-Nokia exec was part of the Meego division. The newly founded HP Mobility will focus on consumer tablets; 'business' tablets (presumably running Windows 8) will remain in their current division. With the recent spinning off of the webOS team into Gram this might mean new webOS hardware.

How To Line a Thermonuclear Reactor 184

sciencehabit writes "One of the biggest question marks hanging over the ITER fusion reactor project — a giant international collaboration currently under construction in France — is over what material to use for coating its interior wall. After all, the reactor has to withstand temperatures of 100,000C and an intense particle bombardment. Researchers have now answered that question by refitting the current world's largest fusion device, the Joint European Torus (JET) near Oxford, U.K., with a lining akin to the one planned for ITER. JET's new 'ITER-like wall,' a combination of tungsten and beryllium, is eroding more slowly (PDF) and retaining less of the fuel than the lining used on earlier fusion reactors, the team reports."

Scientists Store Entire Textbook In DNA 160

sciencehabit writes with this mind-boggling bit from Science Magazine: "When it comes to storing information, hard drives don't hold a candle to DNA. Our genetic code packs billions of gigabytes into a single gram. A mere milligram of the molecule could encode the complete text of every book in the Library of Congress and have plenty of room to spare. All of this has been mostly theoretical—until now. In a new study, researchers stored an entire genetics textbook in less than a picogram of DNA — one trillionth of a gram — an advance that could revolutionize our ability to save data."
