Submission + - SPAM: Researchers Teach Human Brain Cells in a Dish to Play "Pong"

Hmmmmmm writes: Researchers at the biotechnology startup Cortical Labs have created “mini-brains“ consisting of 800,000 to one million living human brain cells in a petri dish, New Scientist reports. The cells are placed on top of a microelectrode array that analyzes the neural activity.

To teach the mini-brains the game, the team created a simplified version of “Pong” with no opponent. A signal is sent to either the right or left of the array to indicate where the ball is, and the neurons from the brain cells send signals back to move the paddle.

Kagan said that while the mini-brains can’t play the game as well as a human, they do learn faster than some AIs.

“The amazon aspect is how quickly it learns, in five minutes, in real time,” he told New Scientist. “That’s really an amazing thing that biology can do.”

While this is certainly some amazing Twitch fodder, the team at Cortical Labs hope to use their findings to develop sophisticated technology using “live biological neurons integrated with traditional silicon computing,” according to the outfit’s website.

Submission + - SPAM: Forget dogs: These rats could be the future of search and rescue

sciencehabit writes: Think search and rescue animal, and you’re likely to picture a dog in an orange vest. But a Tanzanian nonprofit wants you to imagine something else: the African giant pouched rat. Donna Kean and her colleagues at APOPO, a nonprofit that trains pouched rats to save lives, have spent the past 2 decades working with the curious animals (Cricetomys ansorgei) to sniff out tuberculosis and track down land mines. Now, they’re moving on to search and rescue.

Science caught up with Kean to chat about the new project, known as RescueRats. Topics include, jus how to train a rat, what advantages they have over dogs, and whether people would be freaked out about a rodent coming to save them.

Submission + - The war over Chinese Wikipedia (fastcompany.com)

harrymcc writes: Earlier this year, the Wikimedia Foundation banned or demoted many of its editors responsible for the Chinese version of the encyclopedia. The foundation accused these volunteers of biasing it in favor of the Chinese government’s viewpoint. Over at Fast Company, we’ve published Alex Pasternack’s investigation into the story behind this incident, which involves beatings, doxxings, and harassment designed to ensure pro-Beijing content. With Wikipedia versions in other countries also under pressure of a variety of sorts, what’s happening in China is big—but hardly unique.

Could There Be Life On Titan? 122

Adam Korbitz writes "Astrobiology Magazine reports on new research indicating extremophile microbes may be able to live on Titan, the sixth and largest moon of Saturn — in spite of the fact that the moon is largely ice and covered with lakes of liquid methane. Titan joins Mars, Venus, Europa and Enceladus as a potential home to extremophile life in our solar system."

Nvidia Claims Intel's Larrabee Is "a GPU From 2006" 278

Barence sends this excerpt from PC Pro: "Nvidia has delivered a scathing criticism of Intel's Larrabee, dismissing the multi-core CPU/GPU as wishful thinking — while admitting it needs to catch up with AMD's current Radeon graphics cards. 'Intel is not a stupid company,' conceded John Mottram, chief architect for the company's GT200 core. 'They've put a lot of people behind this, so clearly they believe it's viable. But the products on our roadmap are competitive to this thing as they've painted it. And the reality is going to fall short of the optimistic way they've painted it. As [blogger and CPU architect] Peter Glaskowsky said, the "large" Larrabee in 2010 will have roughly the same performance as a 2006 GPU from Nvidia or ATI.' Speaking ahead of the opening of the annual NVISION expo on Monday, he also admitted Nvidia 'underestimated ATI with respect to their product.'"

Best Western Loses Details On 8 Million Customers 180

Albanach writes "Scotland's Sunday Herald newspaper has an exclusive report that the Best Western hotel chain has lost the personal details of each and every guest who has stayed at any of its 1300 hotels in the past 12 months. This amounts to details on 8 million customers and includes information such as name, address, credit card details and employment details. The data even includes future booking details, causing speculation that homes could be targeted for burglary when it's anticipated they will be unoccupied. A Best Western spokesperson is quoted as saying 'Best Western took immediate action to disable the compromised log-in account in question. We are currently in the process of working with our credit card partners to ensure that all relevant procedural standards are met, and that the interests of our guests are protected.'"

How To See In Four Dimensions 227

An anonymous reader writes "Think it's impossible to see four-dimensional objects? These videos will show you otherwise. Some mathematicians work with four-dimensional objects all the time, and they've developed some clever tricks to get a feeling for what they're like. The techniques begin by imagining how two-dimensional creatures, like those in Edwin Abbot's 'Flatland,' could get a feeling for three-dimensional objects. When those techniques are transferred up a dimension, the results are gorgeous."

A Turning Point for Touch Screens, Says the NYT 129

The New York Times has a story up on the suddenly brisk market for touch screens and the devices which can make use of them, which it says "has grown quietly for years, both in commercial applications and in consumer devices." Besides the obvious (the iPhone, and Apple's use of multi-touch generally), the article also mentions the recent inclusion of Israeli company N-Trig's version of multi-touch technology in a Dell notebook computer, and some of the other places you can expect to see touchscreens instead of display-only ones in the near future — if the price drops quickly enough.

Solving Sudoku With dpkg 190

Reader Otter points out in his journal a very neat use for the logic contained in Debian's package dependency resolver: solving sudoku puzzles. To me at least, this is much more interesting than the sudoku puzzles themselves. Update: 08/24 02:51 GMT by T : Hackaday just ran a story that might tickle the same parts of your brain on a game played entirely with MySQL database queries.

Full Facial Transplant Is One Step Closer 113

Hugh Pickens writes "A Chinese medical team led by Shuzhong Guo of the Fourth Military Medical University in Xi'an has successfully completed the first transplant to include facial bone in a transplant on a man whose face was slashed by a bear. The Chinese graft included muscles, nerves, blood vessels, cartilage and skin and included an intact salivary gland, another first. Two years after the procedure, the man can eat, drink and speak, thanks to the gradual fusing of transplanted nerves and muscles with what remained of the patient's own. This transplant together with the another ground breaking transplant last year by French doctors that removed a huge tumor that had completely infiltrated and disfigured their patient's face, now sets the stage for a full facial transplant."

5 Ways Newspapers Botched the Web 136

nicholas.m.carlson writes "Remember Knight-Ridder and AT&T's Viewtron from 1983? With a $900 terminal and $12 a month, you could access news from the Miami Herald and the New York Times, online shopping, banking and food delivery, via a 300-baud modem. After sinking $16 million a year into the project, Knight-Ridder shut it down in 1986. That's just the earliest of the 5 newspaper failures on the Web that Valleywag details in this post, writing: 'each tale ends the same way: A promising start, shuttered amid fear, uncertainty, and doubt.'"

MediaSentry Defied Michigan Investigation For Months 97

NewYorkCountryLawyer writes "You may recall that MediaSentry, the RIAA's unlicensed investigator, has been the subject of an investigation by Michigan's Department of Labor and Economic Growth for its conduct of investigations without an investigator's license, an investigation in which it has made contradictory and false statements to the government's investigators. Well apparently this didn't deter MediaSentry from simply continuing its practice of conducting 'investigations' without a license. In Michigan, no less. We have learned from court papers (PDF) filed in Michigan that the practice continued for months after the DLEG had begun questioning the practice."

A Full-Time 2-Way Video Link To Grandparents? 240

uid7306m writes "We have elderly parents who live a long way off. However, my technological radar tells me that it's possible to set up a 24/7 video link between our kitchen and theirs. It'd be good for our kids and good for the parents, and we can now get pretty cheap nearly unlimited broadband connections at this end (UK). What's the best way to do it? Has anyone tried it? On the far end, it ought to have, in Dilbert's(TM) immortal words 'One big button on it, and we push it for you in the factory.'"
