Submission + - Physicists claim detection of dark matter (

grouchomarxist writes: Physicists at the University of Michigan claim that they have made the first detection of dark matter. 'Dark matter, whose composition is still a mystery, doesn't emit or absorb light, so astronomers can't see it directly with telescopes. They deduce that it exists based on how its gravity affects visible matter. Scientists estimate that dark matter makes up more than 80 percent of the universe. To "see" the dark matter component of the filament that connects the clusters Abell 222 and 223, Dietrich and his colleagues took advantage of a phenomenon called gravitational lensing. They were able to determine the extent to which the supercluster distorted galaxies, and with that information, they could plot the gravitational field and the mass of the Abell 222 and 223 clusters. "It looks like there's a bridge that shows that there is additional mass beyond what the clusters contain, the clusters alone cannot explain this additional mass," Dietrich said.'

Feed Engadget: Zune vs. iPod specification smackdown (

Filed under: Features, Portable Audio, Portable Video

The new Zunes are official so let's get to it: a spec-by-spec scrap between Redmond's new Zunes and Cupertino's formidable iPod foe. Unfortunately, Microsoft failed to mention the all important battery performance of their new gear in addition to a few other minor details. Microsoft fans will tell you that's due to an iPhone-like surprise close to the November launch while haters will jump to the conclusion that this is a definite sign of trouble. Still even without that morsel, there's plenty of data to masticate for comparison. The Zune 80GB certainly holds its own when pitted against the 80GB iPod classic on a specification table. That's not the case, however, with the iPod touch as long as you're willing to sacrifice the bytes for the touch's bigger display and heftier price tag. It's a tougher call on the flash-based Zune vs. the iPod nano -- just how important is WiFi to you on a 1.8-inch display? None of this, of course, accounts for the oh so important user experience or the ecosystems supporting their respective players. As such, we'll reserve final judgment until we have the new Zunes in-hand. Until then you'd best dig in fanboys, that November release is a long way off. The tables that follow will provide the fuel to fight the flame wars for the weeks to come.
