Kiera Wilmot, the Florida high school student who was expelled from her school
after an unauthorized science experiment was misperceived as a weapon (at least for purposes of arrest and charging), won't be going to jail. She will, though, be going to Space Camp
, thanks to a crowdfunding campaign started by author and former NASA engineer Homer Hickham
. All charges against her have been dropped.Read Replies (0)

In the past few days, several readers have submitted word of a paper published on Arxiv allegedly confirming the efficacy
of Andrea Rossi's "E-Cat
," a device Rossi says transmutes nickel into copper, producing cheap energy in the process. (Mentioned before on Slashdot
.) Ethan Siegel of ScienceBlogs takes a skeptical look at the buzz surrounding this paper, and asks some seemingly obvious questions, pointing out various ways in which the cold-fusion / cheap-energy claims could be either confirmed or debunked. First time accepted submitter CdXiminez writes with a capsule of Siegel's points: "What would it take to convince a reasonable observer that you've got a controlled nuclear reaction going on here? Things not shown in the earlier report: Show that nuclear transmutation has in fact taken place; Start the device operating by whatever means you want, then disconnect all external power to it, and allow it to run; Place a gamma-ray detector around the device; Accurately monitor the power drawn from all sources to the device at all times, while also monitoring the energy output from the device at all times."Read Replies (0)

Vigile writes "When NVIDIA released the GTX Titan in February, it was the first consumer graphics card to use the GK110 GPU from NVIDIA that included 2,688 CUDA cores / shaders and an impressive 6GB of GDDR5 frame buffer. However, it also had a $1000 price tag that was the limiting specification for most gamers. With today's release of the GeForce GTX 780 they are hoping to utilize more of the GK110 silicon they are getting from TSMC while offering a lower cost version with performance within spitting range. The GTX 780 uses the same chip but disables a handful more compute units to bring the shader count down to 2,304 — still an impressive bump over the 1,536 of the GTX 680. The 384-bit memory bus remains though the frame buffer is cut in half to 3GB. Overall, the performance of the new card sits squarely between the GTX Titan ($1000) and AMD's Radeon HD 7970 GHz Edition ($439), just like its price. The question is, are PC gamers willing to shell out $220+ dollars MORE than the HD 7970 for somewhere in the range of 15-25% more performance?"
As you might guess, there's similarly spec-laden coverage at lots of other sites, including Tom's

Nyder writes "Kim Dotcom posted via Twitter, with a link to Torrentfreak, that he owns a security patent US6078908, titled 'Method for authorizing in data transmission systems.'"
Techdirt points out that Dotcom isn't just asking
for financial help: Instead, he's asking companies which use two-factor authentication "to help fund his defense, in exchange for not getting sued for the patent
. He points out that his actual funds are still frozen by the DOJ and (more importantly) that his case actually matters a great deal to Google, Facebook and Twitter, because the eventual ruling will likely set a precedent that may impact them -- especially around the DMCA."

: Why is this relevant to Twitter? If you're not an active Twitter user, you might not realize that (after some well publicized twitter-account hijackings), the company is trying to regain some ground on security. Nerval's Lobster writes
