eldavojohn writes "Space.com's Mystery Monday has an article proposing a hypothesis that our solar system's undulations directly affects biodiversity on earth through cosmic-ray exposure. There's data that, through the fossil record, shows us earth's biodiversity peaking again and again until a great cataclysmic period where it is greatly reduced. The theory essentially suggests that this 62 million year cycle can be attributed to how our solar system moves within the milky way galaxy which turns out to be a 64 million year cycle. It's a plausible explanation though very tough to prove, hopefully we don't have to wait around 64 million years to draw a conclusion on this hypothesis."

smooth wombat writes "A committee of the National Academy of Sciences, headed by Richard Anthens, has warned that 'the vitality of Earth science and application programs has been placed at substantial risk by a rapidly shrinking budget.' The list of Earth-observing satellite programs affected is a long one and includes satellite programs which observe nearly every aspect of Earth's climate. A delay in launching a replacement satellite or the disabling of a current satellite without a replacement could mean that data necessary to monitor or predict an upcoming event would be severely restricted. For its part NASA says that tight budgets force it to cut funding for all but the most vital programs. 'We simply cannot afford all of the missions that our scientific constituencies would like us to sponsor,' NASA administrator Michael Griffin told members of Congress when he testified before the House Science Committee February 16."

An anonymous reader writes "Reuters is reporting that chip giant Intel hopes to get back on track in their continued market share war with AMD when they unveil a new line of chips at their upcoming twice-annual developers forum. From the article: 'AMD, once content to mimic Intel's advances, has set the technological pace in recent years with innovations such as putting two processing cores in a single chip -- moves that have helped it gobble market share from its much-larger rival.'"

An anonymous reader writes "Capital Hill Blue is reporting that recently a retired Texas schoolteacher and his wife had a little run in with the Department of Homeland Security. The crime? Paying down some debt. From the article: 'The balance on their JCPenney Platinum MasterCard had gotten to an unhealthy level. So they sent in a large payment, a check for $6,522. And an alarm went off. A red flag went up. The Soehnges' behavior was found questionable. [...] They were told, as they moved up the managerial ladder at the call center, that the amount they had sent in was much larger than their normal monthly payment. And if the increase hits a certain percentage higher than that normal payment, Homeland Security has to be notified.'"

iamlucky13 writes "Private aerospace firm SpaceX has revealed that it has secretly been working on a crew and cargo vehicle since late 2004. Development of the capsule, named Dragon, has so far been funded by SpaceX and its partners, which includes the Canadian company that built the robotic arm for the International Space Station. Dragon would be launched atop a SpaceX Falcon 9 and dock at the ISS with assistance of the robotic arm. While SpaceX founder Elon Musk is prepared to complete development of the capsule with his own resources, SpaceX is seeking funding from NASA's Commercial Orbital Transportation Services program, which makes up to $500 million available through 2010 for private spacecraft development."

ninja_assault_kitten writes "ZDnet is running an article on how a Swedish Mac OS X enthusiast held a competition to prove how good security was on his new fully patched Mac Mini was. Unfortunately, 30 minutes after the competition began, a hacker known as 'gwerdna' had broken in and defaced the website, thus winning the contest. According to gwerdna, 'Mac OS X is easy pickings for bug finders. That said, it doesn't have the market share to really interest most serious bug finders.'." It's also worth noting a piece that says all the security news is much ado about nothing, in practical terms. The security contest also allowed people to have local access via SSH, so that had a lot to do with the crack.

deeptrace writes "The Living on Earth show on NPR recently had a segment on the future of Nuclear Energy. The nearly hour long show is available as an mp3 and in transcript form. It talks about hot fusion, cold fusion, and Pebble Bed Reactors. It provides a well balanced and informative overview of progress towards their use for future nuclear power generation. Most interestingly, they talk with Dr. Pamela Boss and Dr. Stanislaw Szpak at the Space and Naval Warfare Systems Center in San Diego. Dr. Szpak says of their cold fusion experiments: 'We have 100 percent reproducible results'."
