Canadarm2 and HTV-3
NASA – In the grasp of the International Space Station‘s robotic Canadarm2, the HTV-3 Exposed Pallet is moved for installation on the Japan Aerospace Exploration Agency (JAXA) H-II Transfer Vehicle (HTV-3) currently docked to the space station. Earth’s horizon and the blackness of space provide the backdrop for the scene.

R&D Mag – Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell uses mechanical energy more efficiently than systems using separate generators and batteries.
“People are accustomed to considering electrical generation and storage as two separate operations done in two separate units,” says Zhong Lin Wang, a Regents professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. “We have put them together in a single hybrid unit to create a self-charging power cell, demonstrating a new technique for charge conversion and storage in one integrated unit.”
The research was reported in Nano Letters. more> http://tinyurl.com/8b7ys5d

By Carolyn Duffy Marsan – The number of college students pursuing computer science degrees at U.S. universities rose in 2008 for the first time in six years, according to a just released study. Academia and policymakers are hailing the news, but the question facing CIOs and others in charge of IT hiring is: How much do computer science degrees matter? more> http://tinyurl.com/dd5ss7
