Intel To Buy Smartphone Chipmaker Infineon For $2B 95

sylverboss writes "Intel Corp., the world's largest chipmaker, is close to an agreement to buy Infineon Technologies AG's wireless business, three people with direct knowledge of the discussions said. When it comes to desktop, laptop and server chips, Intel's pretty much got a lock on the market but everyone can see the writing on the wall: mobile chips and architectures are the future of computing thanks to the popularity of smartphones, but Intel doesn't have anything to offer in that regard. Don't know Infineon? You should: they are the guys who have supplied Apple with their iPhone baseband chips since 2007."

The Fuel Cost of Obesity 285

thecarchik writes "America loves to complain about gas mileage and the cost of gasoline. As it turns out, part of the problem is us. How much does it really matter? A study by the Centers for Disease Control and Prevention found a 1.1 percent increase in self-reported obesity, which translates into extra weight that your vehicle has to haul around. The study estimates that 1 billion extra gallons of fuel were needed to compensate for passenger weight gained between 1960 and 2002."

Spinal-Fluid Test Confirmed To Predict Alzheimer's 138

omnibit writes "The New York Times reports that researchers have found a spinal-fluid test can be 100 percent accurate in identifying patients with significant memory loss who are on their way to developing Alzheimer's disease. The new study included more than 300 patients in their seventies, 114 with normal memories, 200 with memory problems, and 102 with Alzheimer's disease. Their spinal fluid was analyzed for amyloid beta, which forms plaques in the brain, and for tau, another protein that accumulates in dead and dying nerve cells in the brain. Nearly every person with Alzheimer's had the characteristic spinal fluid protein levels."

Claimed Proof That P != NP 457

morsch writes "Researcher Vinay Deolalikar from HP Labs claims proof that P != NP. The 100-page paper has apparently not been peer-reviewed yet, so feel free to dig in and find some flaws. However, the attempt seems to be quite genuine, and Deolalikar has published papers in the same field in the past. So this may be the real thing. Given that $1M from the Millennium Prize is involved, it will certainly get enough scrutiny. Greg Baker broke the story on his blog, including the email Deolalikar sent around."

Global Warming 'Undeniable,' Report Says 1657

BergZ writes "Scientists from around the world are providing even more evidence of global warming. 'A comprehensive review of key climate indicators confirms the world is warming and the past decade was the warmest on record,' the annual State of the Climate report declares. Compiled by more than 300 scientists from 48 countries, including Canada, the report from the National Oceanic and Atmospheric Administration said its analysis of 10 indicators that are 'clearly and directly related to surface temperatures, all tell the same story: Global warming is undeniable.'"

Nokia Siemens To Buy Motorola Unit For $1.2B 70

sylverboss writes with news that Nokia Siemens is buying Motorola's wireless networks division for $1.2 billion. "The deal gives Nokia — the world's leading supplier of mobile handsets — an invigorated entrance to the US market where it has lagged far behind other handset suppliers." According to BusinessWeek, "Motorola’s sale of the wireless-network unit prepares it for a broader restructuring. The company is planning to spin off its mobile-phone and set-top box operations into a company that will be led by co-Chief Executive Officer Sanjay Jha. The spinoff is on schedule for the first quarter, Jha said last month."

Caffeine Addicts Get No Additional Perk, Only a Return To Baseline 506

Dthief writes "Bristol University researchers found that coffee drinkers develop a tolerance to both the anxiety-producing and the stimulating effects of caffeine, meaning that it only brings them back to baseline levels of alertness, not above them. 'Although frequent consumers feel alerted by caffeine, especially by their morning tea, coffee, or other caffeine-containing drink, evidence suggests that this is actually merely the reversal of the fatiguing effects of acute caffeine withdrawal,' wrote the scientists, led by Peter Rogers of Bristol's department of experimental psychology."

Smokescreen, a JavaScript-Based Flash Player 356

Tumbleweed writes "How to make Steve Jobs your mortal enemy: Smokescreen, a 175KB, 8,000-line JavaScript-based Flash player written by Chris Smoak at RevShock, a mobile ad startup, and to be open-sourced 'in the near future.' From Simon's blog: 'It runs entirely in the browser, reads in SWF binaries, unzips them (in native JS), extracts images and embedded audio, and turns them into base64 encoded data: URIs, then stitches the vector graphics back together as animated SVG. ... Smokescreen even implements its own ActionScript bytecode interpreter.' Badass!"

Man Builds His Own Subway 174

jerryjamesstone writes "Everybody is into rail these days; it is the greenest way to get around next to a bike. Leonid Mulyanchik has been into it for years since before the Berlin Wall fell, since before the first Macintosh, building his own private underground Metro railway system. English-Russia says that he has been doing it with his pension, that it is all legal and approved and that he is still at it. Gizmodo calls it 'Partly the traditional, inspiring, one man against all odds type of persistence, but more the obsessive, borderline insane persistence.'" Update: 06/02 07:33 GMT by T : And if you're the type to visit Burning Man, you can actually ride a home-made monorail this summer, too.
