New Theory Explains Periodic Mass Extinctions 383

Posted by Zonk from the we're-not-due-for-a-little-while-yet dept.
i_like_spam writes "The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalactic cosmic rays causes mass extinctions. The original paper describing the findings is available online."

How to get a Refund on Your Unwanted Windows 409

Posted by Zonk from the breaking-the-window-and-climbing-out dept.
lisah writes "Serge Wroclawski recently contacted Dell to request a refund on the unwanted copy of Windows XP that came pre-installed on his computer. Somewhat surprisingly, Dell complied. Wroclawski admits that the $52.50 refund was more of a victory in principal than anything else, but it was a success nonetheless. Using his tips and techniques readers can try their hand at getting a refund of their own. Wroclawski cautions that you should be prepared for a long haul: the process could take hours."

Firefox 2.0 Wins Phishfight Against IE7 181

Posted by Zonk from the hi-ya dept.
An anonymous reader writes "A new study that pitted the anti-phishing technology in Firefox 2.0 against that of IE7 generated some interesting results. From the Washingtonpost.com story: 'Firefox blocked 243 phishing sites that IE7 overlooked, while IE7 locked 117 sites that Firefox did not.' Microsoft responded by pointing to its own supposed comparison study that put it in front of Mozilla and others in phish fighting, but the story notes: '3Sharp, the company that authored the Microsoft study, clearly state on their site that their goal in creating 3Sharp was "to use the robustness, flexibility, and sheer native capabilities of the Microsoft communication and collaboration technologies to enhance the business of our customers."'"
