Submission + - Stanford bioengineers develop "Neurocore" chips 9,000 times faster than a PC

kelk1 writes: From the Stanford News Service:

Stanford bioengineers have developed faster, more energy-efficient microchips based on the human brain – 9,000 times faster and using significantly less power than a typical PC. This offers greater possibilities for advances in robotics and a new way of understanding the brain. For instance, a chip as fast and efficient as the human brain could drive prosthetic limbs with the speed and complexity of our own actions.

Boahen and his team have developed Neurogrid, a circuit board consisting of 16 custom-designed "Neurocore" chips. Together these 16 chips can simulate 1 million neurons and billions of synaptic connections. The team designed these chips with power efficiency in mind. (...) The result was Neurogrid – a device about the size of an iPad that can simulate orders of magnitude more neurons and synapses than other brain mimics on the power it takes to run a tablet computer.

But much work lies ahead. Each of the current million-neuron Neurogrid circuit boards cost about $40,000. (...) Neurogrid is based on 16 Neurocores, each of which supports 65,536 neurons. Those chips were made using 15-year-old fabrication technologies. By switching to modern manufacturing processes and fabricating the chips in large volumes, he could cut a Neurocore's cost 100-fold – suggesting a million-neuron board for $400 a copy. With that cheaper hardware and compiler software to make it easy to configure, these neuromorphic systems could find numerous applications.

Submission + - Microsoft continues to lose money with each Surface it sells, tablet share at 6% 1

DroidJason1 writes: Revealed from a 10-Q filed by Microsoft with the US Securities and Exchange Commission (SEC), Microsoft has been losing $300 million and counting for the Surface in the last nine months. Data from Strategy Analytics has also revealed that Microsoft's Windows-powered tablets now own a 6% global tablet share, in Q1 of 2014. Android, on the other hand, remains at the top with a 66% global share. Apple's iOS fell to 28%.

Submission + - Microsoft's Antivirus Flags Google.com as Malicious (krebsonsecurity.com)

tsu doh nimh writes: Computers running Microsoft‘s antivirus and security software may be flagging google.com — the world’s most-visited Web site — as malicious, apparently due to a faulty Valentine’s Day security update shipped by Microsoft. For several hours on Tuesday, PC users browsing with Internet Explorer on a machine equipped with Microsoft Security Essentials or Forefront and Internet Explorer saw warnings that Google.com was serving up a “severe” threat – Exploit:JS/Blacole.BW — basically that google.com was supposedly infected with a Blackhole exploit kit. The warning prompted users to "delete" the threat, although accepting the default action appeared to cause no ill result. The episode is more embarrassing than harmful, given that Microsoft is expected to ship antivirus technology with the next version of Windows.

Submission + - Facebook to share private data (allthingsd.com) 1

tomhudson writes: "If you're still looking for a reason to hate Facebook, allthingsd is reporting that Facebook has agreed to share users PRIVATE data with Politico.

Most notably, the Facebook-Politico data set will include Facebook users’ private status messages and comments.

every post and comment — both public and private — by a U.S. user that mentions a presidential candidate’s name will be fed through a sentiment analysis tool

Yes, they claim it will be anonymized. We've seen that doesn't really work in real life."

Submission + - Google Patents Caching MLK Day Search Results

theodp writes: Google remembers Dr. Martin Luther King, Jr. not only with its Doodles, but also with its patents. 'Right around the Martin Luther King Holiday,' explained Google in its application for a recently-granted patent on Discovery of Short-Term and Emerging Trends in Computer Network Traffic, 'there may be many searches about "Martin Luther King"...Thus, it would be useful to have better methods of detecting short term trends for the purposes of caching search results to making them more readily available to users.' You may call the invention of detecting and caching MLK Day Sale search results patently obvious, but the USPTO calls it U.S. Patent No. 8,082,342. Hey, at least it's arguably better than the patents issued to Microsoft and Google for avoiding walking or driving down Martin Luther King Boulevard!

The Continued Censorship of Huckleberry Finn 1073

eldavojohn writes "Over a hundred years after the death of its author, The Adventures of Huckleberry Finn will be released in a censored format, removing two derogatory racial slurs: 'injun' and 'nigger.' The latter appears some 219 times in the original novel but both will be replaced by the word 'slave.' An Alabama publisher named NewSouth Books will be editing and censoring the book so that schools and parents might provide their children the ability to study the classic without fear of properly addressing the torturous history of racism and slavery in The United States of America. The Forbes Blog speculates that e-readers could provide us this service automatically. Salon admirably provides point versus counterpoint while the internet at large is in an uproar over this seemingly large acceptance of censorship as necessary even on books a hundred years old. The legendary Samuel Langhorne Clemens himself once wrote, 'the difference between the almost right word and the right word is really a large matter,' and now his own writing shall test the truth in that today."

Scientists Overclock People's Brains 314

arshadk writes with this excerpt from the BBC about researchers at Oxford University who found that inducing a small current in a subject's parietal lobe boosted their capacity for numerical learning: "The current could not be felt, and had no measurable effect on other brain functions. As it was turned on, the volunteers tried to learn a puzzle which involved substituting numbers for symbols. Those given the current from right to left across the parietal lobe did significantly better when given, compared to those who were given no electrical stimulation. The direction of the current was important — those given stimulation running in the opposite direction, left to right, did markedly worse at these puzzles than those given no current, with their ability matching that of an average six-year-old. The effects were not short-lived, either. When the volunteers whose performance improved was re-tested six months later, the benefits appear to have persisted. There was no wider effect on general maths ability in either group, just on the ability to complete the puzzles learned as the current was applied."

Chip Allows Blind People To See 231

crabel writes "3 blind people have been implanted with a retinal chip that allowed them to see shapes and objects within days of the procedure. From the article: 'One of the patients surprised researchers by identifying and locating objects on a table; he was also able to walk around a room unaided, approach specific people, tell the time from a clock face, and describe seven different shades of gray in front of him.'"

Ozzy Osbourne's Genome Reveals Some Neanderthal Lineage 151

ByOhTek writes "CNN reports that in July, rocker Ozzy Osbourne became one of few to submit his blood to have his full genome sequenced and analyzed. The results are in, and it turns out his genome reveals some Neanderthal lineage. What does Ozzie have to say about it? 'I was curious, given the swimming pools of booze I've guzzled over the years - not to mention all of the cocaine, morphine, sleeping pills, cough syrup, LSD, Rohypnol... there's really no plausible medical reason why I should still be alive. Maybe my DNA could say why,' he wrote."

New Evidence Presented For Ancient Fossils In Mars Rocks 91

azoblue passes along a story in the Washington Post, which begins: "NASA's Mars Meteorite Research Team reopened a 14-year-old controversy on extraterrestrial life last week, reaffirming and offering support for its widely challenged assertion that a 4-billion-year-old meteorite that landed thousands of years ago on Antarctica shows evidence of microscopic life on Mars. In addition to presenting research that they said disproved some of their critics, the scientists reported that additional Martian meteorites appear to house distinct and identifiable microbial fossils that point even more strongly to the existence of life. 'We feel more confident than ever that Mars probably once was, and maybe still is, home to life,' team leader David McKay said at a NASA-sponsored conference on astrobiology."

Is the Line-in Jack On the Verge of Extinction? 411

SlashD0tter writes "Many older sound cards were shipped with line-out, microphone-in, and a line-in jacks. For years I've used such a line-in jack on an old Windows 2000 dinosaur desktop that I bought in 2000 (600 Mhz PIII) to capture the stereo audio signal from an old Technics receiver. I've used this arrangement to recover the audio from a slew of old vinyl LPs and even a few cassettes using some simple audio manipulating software from a small shop in Australia. I've noticed only recently, unfortunately, that all of the four laptops I've bought since then have omitted a line-in jack, forcing me to continue keeping this old desktop on life support. I've looked around for USB sound cards that include a line-in jack, but I haven't been too impressed by the selection. Is the line-in jack doomed to extinction, possibly due to lobbying from vested interests, or are there better thinking-outside-the-box alternatives available?"
