Submission + - Colliding Particles Can Make Black Holes After All (sciencemag.org) 1

cremeglace writes: Particle physicists predict the world's new highest-energy atom smasher, the Large Hadron Collider (LHC) near Geneva, Switzerland, might create tiny black holes, which they say would be a fantastic discovery. Some doomsayers fear those black holes might gobble up Earth--physicist say that's impossible--and have petitioned the United Nations to stop the $5.5 billion LHC. Curiously, though, nobody had ever shown that the prevailing theory of gravity, Einstein's theory of general relativity, actually predicts that a black hole can be made this way. Now a computer model shows conclusively for the first time that a particle collision really can make a black hole. No need to stock up on canned beans for doomsday though--the black holes still require energies vastly exceeding what the LHC is capable of.

Submission + - Electromagnetic Pulse Gun To Help In Police Chases (motorauthority.com) 4

adeelarshad82 writes: In an attempt to put an end to dangerous police high speed chases, scientists at Eureka Aerospace have developed an electromagnetic pulse gun called the High Power Electromagnetic System, or HPEMS. It develops a high-intensity directed pulse of electricity designed to disable a car's microprocessor system, shutting down all of its systems. Right now the prototype seen in a video fills an entire lab, but they have plans to shrink its size to hand-held proportions. Some form of this is already featured in OnStar-equipped vehicles though the electromagnetic signal used to disable the vehicle is beamed via satellite, and doesn't cripple the in-car computer, but rather puts it into a mode that allows police to easily catch and then stop the fleeing criminal.

Prolonged Gaming Blamed For Rickets Rise 254

superapecommando writes "Too many hours spent playing videogames indoors is contributing to a rise in rickets, according to a new study by doctors. Professor Simon Pearce and Dr Tim Cheetham of Newcastle University have written a paper in the British Medical Journal which warns of the rickets uptake – a disease which sufferers get when deficient in Vitamin D. The study boils down to the fact that as more people play videogames indoors they don't get enough sunlight and this has meant the hospitals are now having to combat a disease that was last in the papers around the time Queen Victoria was on the throne." At least the kids are eating enough snacks with iodized salt that we don't have to worry about goiters.

80% of .gov Web Sites Miss DNSSEC Deadline 79

netbuzz writes "Eighty percent of US federal agencies — including the Department of Homeland Security — have missed a deadline to deploy DNS Security Extensions, a new authentication mechanism designed to prevent hackers from hijacking Web traffic. The deadline that whooshed by was Dec. 31, 2009. Experts disagree as to whether this level of deployment represents a failure or reasonable progress toward meeting a mandate set by the Office of Management and Budget in the summer of 2008. OMB officials declined to say why the agency hasn't enforced the DNSSEC deadline for executive branch departments."

Tor Users Urged To Update After Security Breach 161

An anonymous reader writes "If you use Tor, you're cautioned to update now due to a security breach. In a message on the Tor mailing list dated Jan 20, 2010, Tor developer Roger Dingledine outlines the issue and why you should upgrade to Tor 0.2.1.22 or 0.2.2.7-alpha now: 'In early January we discovered that two of the seven directory authorities were compromised (moria1 and gabelmoo), along with metrics.torproject.org, a new server we'd recently set up to serve metrics data and graphs. The three servers have since been reinstalled with service migrated to other servers.' Tor users should visit the download page and update ASAP."

The Apple Tablet Interface Must Be Like This 278

kylevh writes "On one side, there are the people who think that a traditional GUI—one built on windows, folders and the old desktop metaphor—is the only way to go for a tablet. In another camp, there are the ones who are dreaming about magic 3D interfaces and other experimental stuff, thinking that Apple would come up with a wondrous new interface that nobody can imagine now, one that will bring universal love, world peace and pancakes for everyone. Both camps are wrong: The iPhone started a UI revolution, and the tablet is just step two. Here's why." There are lots of cool UI ideas in there, even if it is entirely speculation. It's worth a read just to think about what the future could be like.

FBI Obtains Phone Records With a Post-it Note 187

angry tapir writes "The FBI was so cavalier — and telecom companies so eager to help — that a verbal request or even one written on a Post-it note was enough for operators to hand over customer phone records, according to a damning report (PDF) released on Wednesday by the US Department of Justice Office of the Inspector General."

Microsoft Sues TiVo To Help AT&T 168

Julie188 writes "Microsoft is suing TiVo, claiming patent infringement. Microsoft is doing this because TiVo has sued AT&T — and AT&T happens to be Microsoft's largest customer of Microsoft's Mediaroom IPTV technology. Microsoft says that TiVo has copied Microsoft's Mediaroom IPTV technology in its DVRs. If Microsoft wins, it would effectively block TiVo from selling DVRs without a licensing deal with Microsoft."

Apple Patches Massive Holes In OS X 246

Trailrunner7 writes with this snippet from ThreatPost: "Apple's first Mac OS X security update for 2010 is out, providing cover for at least 12 serious vulnerabilities. The update, rated critical, plugs security holes that could lead to code execution vulnerabilities if a Mac user is tricked into opening audio files or surfing to a rigged Web site."

Obama DOJ Sides With RIAA Again In Tenenbaum 528

NewYorkCountryLawyer writes "Despite having had some time to get their act together, Obama's Department of Justice has filed yet another brief defending the RIAA's outlandish statutory damages theory — that someone who downloaded an mp3 with a 99-cent retail value, causing a maximum possible damages of 35 cents, is liable for from $750 to $150,000 for each such file downloaded, in SONY BMG Music Entertainment v. Tenenbaum. The 25- page brief (PDF) continues the DOJ's practice of (a) ignoring the case law which holds that the Supreme Court's due process jurisprudence is applicable to statutory damages, (b) ignoring the law review articles to like effect, (c) ignoring the actual holding of the 1919 case they rely upon, (d) ignoring the fact that the RIAA failed to prove 'distribution' as defined by the Copyright Act, and (e) ignoring the actual wording and reasoning of the Supreme Court in its leading Gore and Campbell decisions. Jon Newton of p2pnet.net attributes the Justice Department's 'oversights' to the 'eye-popping number of people [in its employ] who worked for, and/or are directly connected with, Vivendi Universal, EMI, Warner Music and Sony Music's RIAA.'"
