Navy Gets 8-Megajoule Rail Gun Working 650

prototypo writes "The Free Lance-Star newspaper is reporting that the Navy Surface Warfare Center in Dahlgren, Virginia has successfully demonstrated an 8-megajoule electromagnetic rail gun. A 32-megajoule version is due to be tested in June. A 64-megajoule version is anticipated to extend the range of naval gunfire (currently about 15 nautical miles for a 5-inch naval gun) to more than 200 nautical miles by 2020. The projectiles are small, but go so fast that have enough kinetic punch to replace a Tomahawk missile at a fraction of the cost. In the final version, they will apex at 95 miles altitude, well into space. These systems were initially part of Reagan's SDI program ("Star Wars"). An interesting tidbit in the article is that the rail gun is only expected to fire ten times or less per day, presumably because of the amount of electricity needed. I guess we now need a warp core to power them."

Seagate Claims 2.5" SCSI Drive is World's Fastest 218

theraindog writes "Seagate has announced a 2.5" SCSI hard drive that spins at an astounding 15,000RPM. The Savvio 15K is the first 2.5" hard drive with a 15K-RPM spindle speed, but what's more interesting is that Seagate claims it's the fastest hard drive on the market. Indeed, the drive boasts an impressive 2.9ms seek time, which is more than half a millisecond quicker than that of comparable 3.5" SCSI drives. The Savvio 15K also features perpendicular recording technology and a claimed Mean Time Between Failures of 1.6 million hours."

YouTube Leaves Google Vulnerable? 208

PreacherTom writes "Yesterday's big news was Google's $1.65 billion deal to acquire popular video hosting service YouTube. But will it be a good deal? The market thinks so, as Google's stock rose about $10 per share after the purchase. On the other hand, YouTube increases Google's risk of copyright infringement, opening the door for significant liability...if Google cannot solve this issue. Will their planned video 'fingerprinting' be enough, or just a billion dollar mistake?" From the article: "YouTube's policy is to remove copyrighted clips once alerted to their existence. Content providers say the company needs to be even more proactive ... Todd Dagres, general partner at Boston's Spark Capital, says that Google's large market cap of $130 billion makes it much more vulnerable to lawsuits than a private company such as YouTube. 'Once Google starts to apply its monetization machine, there is going to be more money at stake and people are going to go after it,' says Dagres. 'You cannot monetize other people's content without their approval.'"

Want to Experience Zero G? Stay in Bed 132

mrogers writes "New Scientist Space is reporting that the health effects of microgravity can be reproduced by staying in bed. Inclining the bed at an angle of 6 degrees with the head at the lower end produces bone and muscle loss, decreases in cardiovascular activity, and reduced capacity to exercise similar to those produced by prolonged spaceflight. (Valeri Polyakov was not available for comment at the time of going to press.)"

Aging Japan Looks to Bots For Care 139

An anonymous reader writes to mention a Yahoo! news article about robotics in Japan. While many research bots are working on interacting with their environment, some of Japan's commercial robotics are focusing on building bots for elderly care. From the article: "The 100-kilogram (220-pound) robot can also distinguish eight different kinds of smells, can tell which direction a voice is coming from and uses powers of sight to follow a human face. 'In the future, we would like to develop a capacity to detect a human's health condition through his breath,' Mukai said. Japan is bracing for a major increase in needs for elderly care due to a declining birth rate and a population that is among the world's longest living." That sure sounds familiar.
