Obama looking at cooling air to fight warming (AP)

April 13, 2009 5:36 am | by SETH BORENSTEIN, AP Science Writer Seth Borenstein, Ap Science Writer – Thu Apr 9, 6:17 am ET | Blogs | Comments

Tinkering with Earth's climate to chill runaway global warming — a radical idea once dismissed out of hand — is being discussed by the White House as a potential emergency option, the president's new science adviser said Wednesday. That's because global warming is happening so rapidly, John Holdren told The Associated Press in his first interview since being confirmed last month. The concept of using technology to purposely cool the climate is called geoengineering

Autonomous military robots: A short survey

April 10, 2009 8:18 am | by Jason Lomberg, Technical Editor | Articles | Comments

The four soldiers move from their concealed position and “stack” themselves, one behind the other, parallel to the door. The #2 man throws an M84 grenade (flashbang) into the room, then yells “frag out!” The flashbang detonates, and the fire team storms through the “fatal funnel” (door). In those first moments, the #1 man must instantaneously...
