An anonymous reader writes “The Empathic Systems Project a Northwestern University demonstrate up to 50% power savings by controlling CPU frequency scaling based upon the end user. They measure the user with eye trackers, galvanic skin response, and force sensors to find a CPU frequency that the user is satisfied with. They are currently studying user activity and system performance on mobile architectures, specifically the Android G1 phone.”

An anonymous reader writes “Space Shuttle Atlantis has finally caught up with the Hubble Space Telescope after following it for several hours. The ‘link up’ between the Space Shuttle and Hubble was a very delicate one as the two were flying through space at 17,200 MPH, 300 miles above the Earth’s surface. The robotic arm of the shuttle grappled the telescope at 1:14 PM EDT today. The telescope will be latched to a high-tech lLzy Susan device known as the Flight Support System for the duration of the servicing work.”
