jan_jes writes to note that The Planetary Society is attempting to crowdfund its own version of the light-powered space-craft popularized by Carl Sagan as a "solar sailer." (YouTube video, with the Society's CEO Bill Nye.) The current model is a CubeSat no bigger than a breadbox with four sails. If the team manages to raise enough money, LightSail will be sent to orbit aboard a SpaceX Falcon Heavy rocket in 2016. LightSail will be released into an orbit with an altitude of 720 kilometers (450 miles), high enough to escape most of the planet's atmospheric drag. Their crowdfunding goal has been far surpassed (more than $476,000 at this writing), but more can't hurt; maybe NASA could use some of the surplus.

masterwit writes "From Scientific American: 'An accidental find in a star-forming dwarf galaxy shows that black holes may mature early in galaxy evolution.' Also, 'if giant black holes in star-forming dwarf galaxies prove to be common — that is, if Henize 2-10 is not an outlier but a representative of a larger population — they may have much to tell about the formation of primordial black holes and galaxies in the early universe.'"

An anonymous reader writes "Micro-blogging site Twitter is opposing an order from a US court to reveal the account details of supporters of WikiLeaks. Twitter has called on Facebook and Google to reveal whether they also received similar court orders. As part of the US government's investigation into WikiLeaks, a court ordered Twitter, in mid-December, to give details of accounts owned by supporters of the whistle-blower site. Twitter has protested against the subpoena and informed the individuals whose account information has been requested, while raising the possibility that other social networking players have received similar orders."

aesoteric writes "An EMC test engineer has pleaded guilty to stealing almost $1 million worth of kit from his employer. He reportedly stole the unspecified goods from the storage giant's North Carolina factory using 'a small bag' to smuggle the kit out before selling it on the internet under a pseudonym."

diegocg writes "Version 2.6.37 of the Linux kernel has been released. This version includes SMP scalability improvements for Ext4 and XFS, the removal of the Big Kernel Lock, support for per-cgroup IO throttling, a networking block device based on top of the Ceph clustered filesystem, several Btrfs improvements, more efficient static probes, perf support to probe modules, LZO compression in the hibernation image, PPP over IPv4 support, several networking microoptimizations and many other small changes, improvements and new drivers for devices like the Brocade BNA 10GB ethernet, Topcliff PCH gigabit, Atheros CARL9170, Atheros AR6003 and RealTek RTL8712U. The fanotify API has also been enabled. See the full changelog for more details."

incuso writes "VisLab announced the most advanced challenge so far ever organized for autonomous vehicles. Two driverless electric cars will perform a trip from Italy to China to demonstrate the feasibility of autonomous driving in real traffic conditions. Each vehicle will be equipped with five laser scanners, seven cameras, GPS, inertial measurement unit, three Linux PCs, and an x-by-wire driving system. The mission will start on July 10 in Milan, Italy, and will reach Shanghai, China, on October 10 (10/10/10) on a 13,000 km route though Italy, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Romania, Ukraine, Russia, Kazakhstan, and finally China."

separsons writes "Scientists at the University of South Carolina recently transformed ordinary T-shirts into bulletproof armor. By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."

matsh sends word that PayPal has frozen the assets of wikileaks.org. From their Web site: "Paypal has as of 23rd of January 2010 frozen WikiLeaks assets. This is the second time that this happens. The last time we struggled for more than half a year to resolve this issue. By working with the respected and recognized German foundation Wau Holland Stiftung we tried to avoid this from happening again — apparently without avail." The submitter adds: "Hopefully we can pressure PayPal to resolve this quickly, since this seems like a dangerous political decision."
