Rambo Tribble writes Researchers from the University of Zurich, ETH Zurich, and University of Fribourg have found evidence that smartphone use changes the way your brain interacts with your thumbs. Using electroencephalography to study brain activity in smartphone users vs. feature-phone users, they found apparently persistent, increased activity in areas of the brain associated with the thumbs. Of course, this may well be true of other repetitive activities, like keyboard use. Reuters provide a bit more approachable coverage.

Lasrick writes: John Mecklin details exactly how nuclear weapons modernization is kick-starting a new arms race, and how modernizing these weapons to make them more accurate and stealthy puts the world at even greater risk of nuclear war: "[T]his is precisely why the U.S. Congress rejected the Air Force’s requests for low-yield, precision-guided nuclear weapons in the 1990s: Their very accuracy increases the temptation to use them." The issue is not getting very much attention, but the patience of the non-nuclear states is wearing thin, and a breakthrough in public awareness may be on the horizon: "The disarmament debate is likely to make this spring's NPT conference a contentious one and just might be loud enough to make the public aware that a new type of nuclear arms race is unfolding around the world."

schwit1 points out a new piece of bipartisan legislation that aims to repeal the Patriot Act and the FISA Amendments Act, which the NSA has used to justify broad domestic surveillance. House Representatives Thomas Massie (R-KY) and Mark Pocan (D-WI) introduced the bill yesterday, calling it the Surveillance State Repeal Act (PDF). Pocan said, "This isn't just tinkering around the edges. This is a meaningful overhaul of the system, getting rid of essentially all parameters of the Patriot Act." The bill also attempts to dramatically strengthen whistleblower protections, so situations like Edward Snowden's and Thomas Drake's don't happen in the future. This legislation is not expected to get the support of Congressional leaders, but supporters hope it will at least inspire some debate about several provisions of the Patriot Act coming up for renewal in June.

angry tapir writes: Researchers at Stanford University have come up with a new way to make chips and solar panels using gallium arsenide, a semiconductor that beats silicon in several important areas but is typically too expensive for widespread use. "[I]t can cost about $5,000 to make a wafer of gallium arsenide 8 inches in diameter, versus $5 for a silicon wafer, according to Aneesh Nainani, who teaches semiconductor manufacturing at Stanford. The new Stanford process (abstract) seeks to lessen this thousand-to-one cost differential by reusing that $5,000 wafer. Today the working electronic circuits in a gallium arsenide device are grown on top of this wafer. Manufacturers make this circuitry layer by flowing gaseous gallium arsenide and other materials across the wafer surface. This material condenses into thin layer of circuitry atop the wafer. In this scenario, the wafer is only a backing. The thin layer of circuitry on top of this costly platter contains all of the electronics."

schwit1 points out a report from Ars Technica on how they used a public records request to acquire an entire License Plate Reader dataset from the Oakland Police Department. The dataset includes 4.6 million total reads from 1.1 million unique plates. They built a custom visualization tool to demonstrate how this data could be abused. "For instance, during a meeting with an Oakland city council member, Ars was able to accurately guess the block where the council member lives after less than a minute of research using his license plate data. Similarly, while "working" at an Oakland bar mere blocks from Oakland police headquarters, we ran a plate from a car parked in the bar's driveway through our tool. The plate had been read 48 times over two years in two small clusters: one near the bar and a much larger cluster 24 blocks north in a residential area—likely the driver's home." Though the Oakland PD has periodically deleted data to free up space — the 4.6 million records were strewn across 18 different Excel spreadsheets with hundreds of thousands of lines each — there is no formal retention limit.

ErnieKey writes: One of the major reasons 3D printing hasn't really caught on is because it's an incredibly slow process. Just last week a company called Carbon3D unveiled a super fast new 3D printing process that utilizes oxygen and light. Now, another company — Gizmo 3D — has unveiled an even faster 3D printing process which is claimed to be more reliable than the process presented by Carbon3D. It can print 30mm in height at a 50 micron resolution in just 6 minutes.

An anonymous reader sends word of Ford's new "Intelligent Speed Limiter" technology, which they say will prevent drivers from unintentionally exceeding the speed limit. When the system is activated (voluntarily) by the driver, it asks for a current maximum speed. From then on, a camera mounted on the windshield will scan the road ahead for speed signs, and automatically adjust the maximum speed to match them. The system can also pull speed limit data from navigation systems. When the system detects the car exceeding the speed limit, it won't automatically apply the brakes — rather, it will deliver less fuel to the engine until the vehicle's speed drops below the limit. If the speed still doesn't drop, a warning noise will sound. The driver can override the speed limit by pressing "firmly" on the accelerator. The technology is being launched in Europe with the Ford S-MAX.

HughPickens.com writes: The atom bomb — leveler of Hiroshima and instant killer of some 80,000 people — is just a pale cousin compared to the hydrogen bomb, which easily packs the punch of a thousand Hiroshimas. That is why Washington has for decades done everything in its power to keep the details of its design out of the public domain. Now William J. Broad reports in the NY Times that Kenneth W. Ford has defied a federal order to cut material from his new book that the government says teems with thermonuclear secrets. Ford says he included the disputed material because it had already been disclosed elsewhere and helped him paint a fuller picture of an important chapter of American history. But after he volunteered the manuscript for a security review, federal officials told him to remove about 10 percent of the text, or roughly 5,000 words. "They wanted to eviscerate the book," says Ford. "My first thought was, 'This is so ridiculous I won't even respond.'" For instance, the federal agency wanted him to strike a reference to the size of the first hydrogen test device — its base was seven feet wide and 20 feet high. Dr. Ford responded that public photographs of the device, with men, jeeps and a forklift nearby, gave a scale of comparison that clearly revealed its overall dimensions.

Though difficult to make, hydrogen bombs are attractive to nations and militaries because their fuel is relatively cheap. Inside a thick metal casing, the weapon relies on a small atom bomb that works like a match to ignite the hydrogen fuel. Today, Britain, China, France, Russia and the United States are the only declared members of the thermonuclear club, each possessing hundreds or thousands of hydrogen bombs. Military experts suspect that Israel has dozens of hydrogen bombs. India, Pakistan and North Korea are seen as interested in acquiring the potent weapon. The big secret the book discusses is thermal equilibrium, the discovery that the temperature of the hydrogen fuel and the radiation could match each other during the explosion (PDF). World Scientific, a publisher in Singapore, recently made Dr. Ford's book public in electronic form, with print versions to follow. Ford remains convinced the book "contains nothing whatsoever whose dissemination could, by any stretch of the imagination, damage the United States or help a country that is trying to build a hydrogen bomb." "Were I to follow all — or even most — of your suggestions," says Ford, "it would destroy the book."

An anonymous reader writes: Fox announced today that The X-Files will return with six new episodes. David Duchovny and Gillian Anderson will both reprise their roles as Mulder and Scully, respectively, and show creator Chris Carter will return as well. Production begins this summer, but air dates are not yet known. The X-Files originally started in 1993 and ran for 9 seasons, spawning two feature films and a short-lived spinoff called The Lone Gunmen. It won 16 Emmy awards and 5 Golden Globe awards before critical reception soured over the last few seasons. Carter said, "I think of it as a 13-year commercial break. The good news is the world has only gotten that much stranger, a perfect time to tell these six stories."

Lucas123 writes Rooftop solar distributor SolarCity announced a new service where it will build a centrally-controllable power grid for cities, business campuses and even islands. Marketing its GridLogic service by calling attention to the recent uptick in natural disasters and the extended power outages that resulted from them, SolarCity said its "microgrids" are fully independent power infrastructures fed by solar panels with lithium-ion backup batteries (courtesy of Tesla). SolarCity claims its GridLogic program can provide electricity to communities and businesses for less than they pay for utility power and the facilities can still be connected to their area's utility power grid as an added backup.

An anonymous reader sends this report from Reuters: IBM Corp will share technology with Chinese firms and will actively help build China's industry, CEO Virginia Rometty said in Beijing as she set out a strategy for one of the foreign firms hardest hit by China's shifting technology policies. IBM must help China build its IT industry rather than viewing the country solely as a sales destination or manufacturing base, Rometty said. ... [Her] remarks were among the clearest acknowledgements to date by a high-ranking foreign technology executive that companies must adopt a different tack if they are to continue in China amid growing political pressure. A number of U.S. technology companies operating in China are forming alliances with domestic operators, hoping a local partner will make it easier to operate in the increasingly tough environment for foreign businesses.

jones_supa writes: A year ago, animation studio Pixar promised its RenderMan animation and rendering suite would eventually become free for non-commercial use. This was originally scheduled to happen in the SIGGRAPH 2014 computer graphics conference, but things got delayed. Nevertheless, today Pixar is releasing the free version into the wild. Free, non-commercial RenderMan can be used for research, education, evaluation, plug-in development, and any personal projects that do not generate commercial profits. This version is fully featured, without a watermark or any kind of artificial limits. Featuring Pixar's new RIS technology, RenderMan delivers extremely fast global illumination and interactive shading and lighting for artists. The software is available for Mac, Linux, and Windows. In conjunction with the release, Pixar has also launched a new RenderMan Community site where users can exchange knowledge and resources, showcase their own work, share assets such as shaders and scripts, and learn about RenderMan from tutorials.
