Media Center PCs

The reason you own a personal computer has changed. These days, it’s far more likely to pump out music, photos and video than spreadsheets and text documents. Yet the way you interact with it hasn’t caught up: alone in an office, two feet from the screen, clicking away with a mouse and keyboard. There ought to be a better way. Companies have nibbled at the entertainment-focused PC interface before, but it took Microsoft to finally nail it, with the recently released Windows XP Media Center Edition 2005...

Can We Stop Storms?

With brutal hurricanes on the rise, scientists turn to far-out technologies to fight them off. Back in the 1960s and '70s, legions of scientists explored technologies to zap strength from hurricanes. Those efforts were scrapped both because experiments were inconclusive and because the cost of deploying a full-scale system to regularly battle the cyclones would have been staggering. In light of Katrina and Rita's $200-billion-plus swath of destruction—and a forecast of even more violent and catastrophic hurricanes to come—that steep price tag now seems like a bargain, and scientists are once again entertaining schemes to mitigate monster storms...

In July, Sullivan demonstrated the world's most advanced robotic arm, using his thoughts alone to maneuver it...

Sunny Future for Nanocrystal Solar Cells

Researchers with Berkeley Lab and the University of California, Berkeley, have developed the first ultra-thin solar cells comprised entirely of inorganic nanocrystals and spin-cast from solution. These dual nanocrystal solar cells are as cheap and easy to make as solar cells made from organic polymers and offer the added advantage of being stable in air because they contain no organic materials...
