sosaited writes "It has been widely believed that our ancestors originated out of Africa, but a paper published in Nature by Carnegie Museum of Natural History scientists puts this in doubt. The paper is based on the fossils of four primate species found in Asia which are 40 million years old, during which period Africa was thought to not have these species. The diversity and timing of the new anthropoids raises two scenarios. Anthropoids might simply have emerged in Africa much earlier than thought, and gone undiscovered by modern paleontologists. Or they could have crossed over from Asia, where evidence suggests that anthropoids lived 55 million years ago, flourishing and diversifying in the wide-open ecological niches of an anthropoid-free Africa."

baronvoncarson tips news that today Valve released an updated version of Alien Swarm, a popular Unreal Tournament 2004 total conversion mod. The creators of the mod were hired by Valve, and they've helped turn it into a stand-alone game running on the Source engine. Valve is also releasing the code base for Alien Swarm and an SDK. The game is available for free on Steam.

Elliot Chang writes "For Sony's newest display, the company decided to throw into the mix ultra-thinness (just 80m or a bit thinner than a human hair) and the energy-saving power of OLEDs. The new prototype is so bendy that it can be wrapped around a pencil while still streaming video!"

pinkstuff writes "The Navy unveiled its terror-fighting marine mammals at a two-day homeland security and disaster preparedness exercise in California this week. From the article: 'A Navy seal — actually a sea lion — took less than a minute to find a fake mine under a pier near San Francisco's AT&T Park. A dolphin quickly located a terrorist lurking in the black water before another sea lion, using a device carried in its mouth, cuffed the pretend saboteur's ankle so authorities could reel him in.' Queue the 'frickin lasers' jokes."

lurking_giant writes "The Seattle Times is reporting that the Men's 500 meter speed-skating competition was delayed more than an hour Monday evening by the breakdown of the two ice grooming machines at the skating oval. The real story is that the machines that failed were the latest state-of-the-art 'Resurfice Fume-Free Electric Groomers' leased to the Olympics committee. An old, propane-powered Zamboni had to be brought out to fix the ice. This makes two nights in a row with ice resurfacing machine failures. If you're going to spend twice as much on electric devices to replace non-green designs, at least test the things first."

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

Hugh Pickens writes "Science Daily reports that using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, astronomers have discovered what may be the coolest sub-stellar body ever found outside our own solar system. Too small to be stars and with insufficient mass to maintain hydrogen-burning nuclear fusion reactions in their cores, 'brown dwarfs' have masses smaller than stars but larger than gas giant planets like Jupiter, with an upper limit in between 75 and 80 Jupiter masses. 'This looks like the fourth time in three years that the UKIRT has made a record breaking discovery of the coolest known brown dwarf, with an estimated temperature not far above 200 degrees Celsius,' says Dr. Philip Lucas at the University of Hertfordshire. Due to their low temperature these objects are very faint in visible light, and are detected by their glow at infrared wavelengths. The object known as SDSS1416+13B is in a wide orbit around a somewhat brighter and warmer brown dwarf, SDSS1416+13A, and the pair is located between 15 and 50 light years from the solar system, which is quite close in astronomical terms."

kghapa writes "Still want to argue that video games shrink your brain? While video games have been previously shown to stimulate brain activity and improve coordination skills, a recently published study has directly linked structures in the human brain with video game aptitude. And yes, apparently size does matter in this case. Quoting: '... each subject received 20 hours of training to play a video game specifically created for research purposes, called Space Fortress. It's basically an Asteroids-type arcade game, in which the object is to knock down and destroy an enemy fortress while dodging space mines. However, the game has lots of extra twists that require close attention. Some of the players were told to focus exclusively on running up a high score, while others were told to shift their priorities between several goals. The result? The subjects who had more volume in an area called the nucleus accumbens did significantly better in the early stages of training. Meanwhile, those who were well-endowed in different areas of the striatum, known as the caudate nucleus and putamen, handled the shifting strategies better.'"

ajs writes "World of Warcraft's Wrath of the Lich King expansion was staggered into 4 phases. The fourth and final phase, patch 3.3, was released on Tuesday. This patch is significant in that it will be the first introduction of one of the most anticipated new features in the game since PvP arenas: the cross-realm random dungeon, as well as the release of new end-game dungeons for 5, 10 and 25-player groups. The patch notes have been posted, and so has a trailer. The ultimate fight against the expansion's antagonist, the Lich King a.k.a. Arthas, will be gated as each of the four wings of the final dungeon are opened in turn — a process that may take several months. The next major patch after 3.3 (presumably 4.0) will be the release of Cataclysm, the next expansion."

Mike writes "An ambitious Arizona company has recently revealed plans for a solar powered bullet train that will streak across the desert at 220 mph, traveling from Tuscon to Phoenix in 30 minutes flat. Proposed by Solar Bullet LLC, the system comprises a series of tracks that would serve stations including Chandler, Casa Grande, Red Rock, and Marana, and may one day be extended to Flagstaff and Nogales. The train would require 110 megawatts of electricity, which would be generated by solar panels mounted above the tracks." Local coverage of the plan takes a harder look, noting that Solar Bullet LLC is two guys who are now asking local governments in the towns at which such a train would potentially stop for $35K for a legal and feasibility study. Total cost is estimated at $27B.

oldspewey writes "A new skin disorder caused by use of games consoles has been identified by skin specialists. The condition, dubbed "PlayStation palmar hidradenitis", is described in the British Journal of Dermatology. Researchers outline the case of a 12-year-old girl who attended a Swiss hospital with intensely painful sores on the palms of her hands. The girl, who had been using a games console regularly, recovered fully after 10 days of abstinence. The doctors suspect that the problem was caused by tight and continuous grasping of the console's hand-grips, and repeated pushing of the buttons, alongside sweating caused by the tension of the game. Nina Goad, of the British Association of Dermatologists said: 'This is an interesting discovery and one that the researchers are keen to share ... If you're worried about soreness on your hands when playing a games console, it might be sensible to give your hands a break from time to time, and don't play excessively if your hands are prone to sweating.'" We called it Tekken thumb.

Clara writes "The YouTube blog has announced that YouTube is on its way to the PlayStation 3 and Wii. From the article: 'Have you ever wanted to just sit on your couch and watch YouTube on your TV? Well, now that's possible via YouTube for Television, initially available through the Sony PS3 and Nintendo Wii game consoles at www.youtube.com/tv. Currently in beta, the TV Website offers a dynamic, lean-back, 10-foot television viewing experience.' No YouTube for Xbox, however (Google must simply not have gotten around to Microsoft yet)."
