Protein Converts Pancreatic Cancer Cells Back Into Healthy Cells

Tue, 04/21/2015 - 12:39pm
An anonymous reader writes: Scientists working in the area of pancreatic cancer research have uncovered a technique that sees cancerous cells transform back into normal healthy cells. The method relies in the introduction of a protein called E47, which bonds with particular DNA sequences and reverts the cells back to their original state. The study (abstract) was a collaboration between researchers at the Sanford-Burnham Medical Research Institute, University of California San Diego and Purdue University. The scientists are hopeful that it could help combat the deadly disease in humans.

Concerns of an Artificial Intelligence Pioneer

Tue, 04/21/2015 - 11:57am
An anonymous reader writes: In January, the British-American computer scientist Stuart Russell drafted and became the first signatory of an open letter calling for researchers to look beyond the goal of merely making artificial intelligence more powerful. "We recommend expanded research aimed at ensuring that increasingly capable AI systems are robust and beneficial," the letter states. "Our AI systems must do what we want them to do." Thousands of people have since signed the letter, including leading artificial intelligence researchers at Google, Facebook, Microsoft and other industry hubs along with top computer scientists, physicists and philosophers around the world. By the end of March, about 300 research groups had applied to pursue new research into "keeping artificial intelligence beneficial" with funds contributed by the letter's 37th signatory, the inventor-entrepreneur Elon Musk. Russell, 53, a professor of computer science and founder of the Center for Intelligent Systems at the University of California, Berkeley, has long been contemplating the power and perils of thinking machines. He is the author of more than 200 papers as well as the field's standard textbook, Artificial Intelligence: A Modern Approach (with Peter Norvig, head of research at Google). But increasingly rapid advances in artificial intelligence have given Russell's longstanding concerns heightened urgency.

Maglev Train Exceeds 600km/h For World Record

Tue, 04/21/2015 - 11:14am
nojayuk writes: An experimental Japanese magnetic levitation train has reached a speed of 603 km/h, breaking the world speed record the same train set last week of 590 km/h. "Central Japan Railway (JR Central), which owns the trains, wants to introduce the service between Tokyo and the central city of Nagoya by 2027. The 280km journey would take only about 40 minutes, less than half the current time. However, passengers will not get to experience the maglev's record-breaking speeds because the company said its trains will operate at a maximum of 505km/h. In comparison, the fastest operating speed of a Japanese shinkansen, or "bullet train" is is 320km/h. ... Construction costs are estimated at nearly $100bn (£67bn) just for the stretch to Nagoya, with more than 80% of the route expected to go through costly tunnels, AFP news agency reports."

Twitter Rolls Out New Anti-Abuse Tools

Tue, 04/21/2015 - 10:32am
An anonymous reader writes: After facing criticism that it gives trolls and hatemongers a platform to intimidate people, Twitter has now rolled out a new set of tools and policies to handle abusive tweets. Previously, they only prohibited threats of violence that were "direct" and "specific," but now that's been expanded to all threats of violence or tweets promoting violence. They said, "Our previous policy was unduly narrow and limited our ability to act on certain kinds of threatening behavior." Twitter has also added non-permanent bans, as well as this: "[W]e have begun to test a product feature to help us identify suspected abusive Tweets and limit their reach. This feature takes into account a wide range of signals and context that frequently correlates with abuse including the age of the account itself, and the similarity of a Tweet to other content that our safety team has in the past independently determined to be abusive." Twitter's general counsel recently said, "Freedom of expression means little as our underlying philosophy if we continue to allow voices to be silenced because they are afraid to speak up. We need to do a better job combating abuse without chilling or silencing speech."

Supreme Court Rules Extending Traffic Stop For Dog Sniff Unconstitutional

Tue, 04/21/2015 - 9:50am
bmxeroh writes: The Supreme Court ruled today (PDF) that a police officer may not extend a traffic stop beyond the time needed to complete the tasks related to that stop for the purposes of allowing a trained dog to sniff for drugs. Justice Ruth Bader Ginsburg wrote for the majority (6-3) that police authority "ends when tasks tied to the traffic infraction are — or reasonably should have been — completed." The case, Rodriguez v. United States, 13-9972, all started with Rodriguez was stopped in Nebraska for driving out of his lane. After he was given the ticket for that infraction, he was made to wait an additional seven to eight minutes for a drug dog to arrive which promptly alerted to the presence of drugs in the car. Upon search, the officers found a small bag of methamphetamine in his possession.

Optical Tech Can Boost Wi-Fi Systems' Capacity With LEDs

Tue, 04/21/2015 - 9:07am
chasm22 writes: Researchers at Oregon State University have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The system can potentially send data at up to 100 megabits per second. Although some current WiFi systems have similar bandwidth, it has to be divided by the number of devices, so each user might be receiving just 5 to 10 megabits per second, whereas the hybrid system could deliver 50-100 megabits to each user.

Copyright For Sale: What the Sony Docs Say About MPAA Buying Political Influence

Tue, 04/21/2015 - 7:35am
An anonymous reader writes: The linkage between political funding and the major copyright lobby groups is not a new issue as for years there have been stories about how groups like the MPAA and RIAA fund politicians that advance their interests. Michael Geist digs into the Sony document leak to see how the MPAA coordinates widespread buying of politicians with political funding campaigns led by former Senator Christopher Dodd to federal and state politicians. The campaigns include efforts to circumvent donation limits by encouraging executives to spend thousands on influential politicians, leading to meetings with Barack Obama, the head of the USTR and world leaders.

Judge Recognizes Research Chimps As "Legal Persons"

Tue, 04/21/2015 - 4:51am
sciencehabit writes: In a decision that effectively recognizes chimpanzees as legal persons for the first time, a New York judge [Monday] granted a pair of Stony Brook University lab animals the right to have their day in court. The ruling marks the first time in U.S. history that an animal has been covered by a writ of habeus corpus, which typically allows human prisoners to challenge their detention. The judicial action could force the university, which is believed to be holding the chimps, to release the primates, and could sway additional judges to do the same with other research animals.

Robot Workers' Real Draw: Reducing Dependence on Human Workers

Tue, 04/21/2015 - 4:10am
HughPickens.com writes: Zeynep Tufekci writes in an op-ed at the NY Times that machines are getting better than humans at figuring out who to hire, who's in a mood to pay a little more for that sweater, and who needs a coupon to nudge them toward a sale. It turns out most of what we think of as expertise, knowledge and intuition is being deconstructed and recreated as an algorithmic competency, fueled by big data. "Machines aren't used because they perform some tasks that much better than humans, but because, in many cases, they do a "good enough" job while also being cheaper, more predictable and easier to control than quirky, pesky humans," writes Tufekci. "Technology in the workplace is as much about power and control as it is about productivity and efficiency." According to Tufekci technology is being used in many workplaces: to reduce the power of humans, and employers' dependency on them, whether by replacing, displacing or surveilling them. Optimists insist that we've been here before, during the Industrial Revolution, when machinery replaced manual labor, and all we need is a little more education and better skills. Tufekci points out that one historical example is no guarantee of future events. "Confronting the threat posed by machines, and the way in which the great data harvest has made them ever more able to compete with human workers, must be about our priorities," concludes Tufekci. "This problem is not us versus the machines, but between us, as humans, and how we value one another."

Tor Is Building the Next Generation Dark Net With Funding From DARPA

Tue, 04/21/2015 - 1:10am
Patrick O'Neill writes: After years of relative neglect, Tor has been able to dedicate increasing time and resources to its hidden services thanks to funding in part by DARPA, as well as an upcoming crowdfunding campaign. DARPA's funding lasts 1-3 years and covers several projects including security and usability upgrades that close the gap between hidden services and the everyday Internet. "Next-generation hidden services may be run from multiple hosts to better deal with denial of service attacks and high traffic in general, a potentially big power boost that further closes the gap between the Dark Net and normal websites. ... Hidden services, which make up about 4 percent of the entire Tor network, have until recently been relatively neglected when it comes to funding and developing."

Baltimore Police Used Stingrays For Phone Tracking Over 25,000 Times

Mon, 04/20/2015 - 8:11pm
An anonymous reader writes The Baltimore Police Department is starting to come clean about its use of cell-phone signal interceptors — commonly known as Stingrays — and the numbers are alarming. According to recent court testimony reported by The Baltimore Sun, the city's police have used Stingray devices with a court order more than 25,000 times. It's a massive number, representing an average of nearly nine uses a day for eight years (the BPD acquired the technology in 2007), and it doesn't include any emergency uses of the device, which would have proceeded without a court order.

For High-End CPUs, Qualcomm Ditches TSMC For Samsung

Mon, 04/20/2015 - 6:18pm
An anonymous reader writes: A report at Re/code says Qualcomm will have its next-gen Snapdragon 820 CPU made at Samsung's foundries, instead of TSMC's. The report points out a couple of good reasons for the switch: first of all, Samsung's plants run on a 14nm process, while TSMC still uses a 20nm process. Second — and more telling — Samsung recently ditched Qualcomm's Snapdragon processors for their new Galaxy S6 smartphone, opting to use their own Exynos chips instead. With the phone expected to sell upwards of 70 million units, that's a huge missed opportunity for Qualcomm. It's feasible Qualcomm could get Samsung to drop its own chips, because the Snapdragon 820 will have an onboard LTE modem. That would reduce the cost of assembling a phone, and also free up some space to make it smaller.

3.46-Billion-Year-Old 'Fossils' Were Not Created By Life Forms

Mon, 04/20/2015 - 5:16pm
sciencehabit writes: What are the oldest fossils on Earth? For a long time, a 3.46-billion-year-old rock from Western Australia seemed to hold the record. A 1993 Science paper (abstract) suggested that the Apex chert contained tiny, wormy structures that could have been fossilized cell walls of some of the world's first cyanobacteria. But now there is more evidence that these structures have nothing to do with life. The elongated filaments were instead created by minerals forming in hydrothermal systems, researchers report (abstract). After the minerals were formed, carbon glommed on to the edges, leaving behind an organic signature that looked suspiciously like cell walls.

Netflix Is Betting On Exclusive Programming

Mon, 04/20/2015 - 4:23pm
An anonymous reader writes: You may have heard of the recent launch of the new Daredevil TV show, and possibly the hit shows House of Cards and Orange is the New Black. They're all original programming from Netflix — the company that used to just mail DVDs to your door. But Netflix is now running a lot more than just those three shows — it has 320 hours of original programming planned for this year. This article discusses how Netflix is betting big on original, exclusive content, and what that means for the future of television. "Traditionally, television networks needed to stand for something to carve out an audience, he said, whereas the Internet allows brands to mean different things to different people because the service can be personalized for individual viewers. That means that for a conservative Christian family, Netflix should stand for wholesome entertainment, and, for a 20-year-old New York college student, it should be much more on the edge, he said.... 'We've had 80 years of linear TV, and it's been amazing, and in its day the fax machine was amazing,' he said. "The next 20 years will be this transformation from linear TV to Internet TV.'"

How Security Companies Peddle Snake Oil

Mon, 04/20/2015 - 3:40pm
penciling_in writes: There are no silver bullets in Internet security, warns Paul Vixie in a co-authored piece along with Cyber Security Specialist Frode Hommedal: "Just as 'data' is being sold as 'intelligence', a lot of security technologies are being sold as 'security solutions' rather than what they really are: very narrow-focused appliances that, as a best case, can be part of your broader security effort." We have to stop playing "cops and robbers" and pretending that all of us are potential targets of nation-states, or pretending that any of our security vendors are like NORAD, warn the authors. Vixie adds, "We in the Internet security business look for current attacks and learn from those how to detect and prevent those attacks and maybe how to predict, detect, and prevent what's coming next. But rest assured that there is no end game — we put one bad guy in prison for every hundred or so new bad guys who come into the field each month. There is no device or method, however powerful, which will offer a salient defense for more than a short time. The bad guys endlessly adapt; so must we. Importantly, the bad guys understand how our systems work; so must we."
