astroengine writes "Helped by the extensive coverage of eyewitness cameras, CCTV footage and a fortuitous observation made by the Meteosat-9 weather satellite, Jorge Zuluaga and Ignacio Ferrin of the University of Antioquia in Medellin, Colombia, have been able to reconstruct the most likely orbit of the meteoroid that slammed into the atmosphere over the Russian Urals region on Feb. 15. What's more, they know what type of space rock it was — the Chelyabinsk-bound meteoroid originated from an Apollo-class asteroid (PDF). Apollo asteroids are well-known near-Earth asteroids that cross the orbit of Earth. Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus — a 10 kilometer-wide monster that was discovered in 1972."
New submitter jollyrgr3 writes "If William Shatner gets his wish, one of Pluto's two new moons will be named Vulcan. The two small moons were discovered recently, and the SETI Institute launched an online poll to let people choose names. Captain Kirk himself suggested the names Vulcan and Romulus. Vulcan was accepted as a candidate, and Shatner exhorted his Twitter followers to vote. Vulcan ended up winning by a landslide, taking 174,000 of the 450,000 total responses. The next highest was Cerberus at just shy of 100,000. The names still have to be approved by the International Astronomical Union, as they have the final say. Leonard Nimoy approves."
AstroPhilosopher writes "In a move not far removed from the model T-101, U.S. researchers have succeeded in re-animating a dead sparrow. Duke scientists were studying male behavior aggression among sparrows. They cleverly decided to insert miniaturized robotics into an empty sparrow carcass and operate it like a puppet (abstract). It worked; they noticed wing movements were a primary sign of aggression. Fortunately the living won out this time. The experiment stopped after the real sparrows tore off the robosparrow's head. But there's always a newer model on the assembly-line. Good luck sparrows." Bad Horse has not yet made a decision on the researchers' application.
Hugh Pickens writes "UPI reports that for the first time in the history of Nobel Prize, one of the Nobel Prize medals, along with the diploma presented by the Nobel committee, is on auction — with an opening bid of $250,000. Awarded to Francis Crick, who along with James Watson and Maurice Wilkins won the Nobel Prize for medicine in 1962 'for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material,' the medal will be auctioned off in New York City, by Heritage Auctions. The medal has been kept in a safe deposit box in California since Crick's widow passed away in 2007 and a portion of the proceeds will go to the Francis Crick Institute of disease research scheduled to open in London in 2015. '"By auctioning his Nobel it will finally be made available for public display and be well looked after. Our hope is that, by having it available for display, it can be an inspiration to the next generation of scientists," says Crick's granddaughter, Kindra Crick. "My granddad was honored to have received the Nobel Prize, but he was not the type to display his awards; his office walls contained a large chalkboard, artwork and a portrait of Charles Darwin."'"
Billy the Mountain writes "A small UK company is bringing new technology online that could reduce the prices of tantalum and titanium ten-fold. According to this piece in The Economist: A tantalising prospect, the key is a technique similar to smelting aluminum with a new twist: The metallic oxides are not melted as with aluminum but blended in powder form with a molten salt that serves as a medium and electrolyte. This technology is known as the FFC Cambridge Process. Other metals include Neodymium, Tungsten, and Vanadium."
carmendrahl writes "Photos used to be second-class citizens in the art world, not considered as prestigious as paintings or sculpture. But that changed in the 1990s. As daguerrotypes and the like started selling for millions of dollars, fakes also slipped in. Unfortunately, the art world didn't have good ways of authenticating originals. Cultural heritage researchers had to play catch-up, and quickly. Two fraud cases, one involving avant garde photographer Man Ray, turned photo conservation from a niche field into a mature science."
