An anonymous reader writes: Biologists have discovered that just like humans, plants can also recognize their relatives.

Matter Discovered Traveling at Near Light Speed 403

mcgrew writes to mention New Scientist is reporting that scientists have clocked matter traveling at 99.999% the speed of light. "The fastest flows of matter in the universe shoot out of dying stars at more than 99.999% the speed of light, new observations reveal. When a massive star runs out of fuel, it collapses to form a black hole or a neutron star. In the process, some of the matter from the star also explodes outward at blistering speeds, producing an intense burst of gamma rays and other radiation."

Submission + - Safari 3 vs. Firefox 2 and IE7 (arstechnica.com)

Bobcat writes: Ars Technica has a 'first look' at Safari for Windows, which is interesting because it's written from the perspective of someone new to Safari. It was tested against Firefox 2 and IE7 and aside from the slightly faster page loading, Ars didn't find much to recommend it to Windows users. 'The modest increase in rendering performance is hardly worth the deficiencies, and Safari's user interface simply doesn't provide the usability or flexibility of competing products. If the folks at Apple think that providing Windows users with a taste of Mac OS X through Safari is going to entice them to buy a Mac, it's going to take a better effort than the Safari 3 beta. Even if the final release is more polished and completely bug-free, it still won't be as powerful or feature-loaded as Opera or Firefox.'
