NASA Offers Careers Program For Texas High School Juniors

NASA is offering high school juniors in Texas an opportunity to explore their interests in space exploration and careers through the High School Aerospace Scholars program.

Three NASA Airborne Earth Science Missions Focus of Jan. 25 Media Day

NASA is inviting media to look behind-the-scenes at several active Earth science missions that will take to the air next month to study climate change and air pollution. These airborne missions are all based at NASA's Dryden Flight Research Center in Southern California.

Fermi Improves its Vision for Thunderstorm Gamma-Ray Flashes

Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA's Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief outbursts of high-energy light mysteriously produced above thunderstorms.

Making insulator conduct

(Phys.org)—New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz domain.

Watch This: Joy to the World From the International Space Station

http://vimeo.com/54269169

The crew of the International Space Station would like to wish you very happy holidays this year, and it comes in the form of this pretty timelapse video. On their wishlist? World peace. They'd like to see a little more cooperation on the beautiful blue marble they orbit.

Fastest light-driven process ever

A discovery that promises transistors -- the fundamental part of all modern electronics -- controlled by laser pulses that will be 10,000 faster than today's fastest transistors has now been made.

Proliferation warnings on nuclear 'wonder-fuel', thorium

Thorium is being touted as an ideal fuel for a new generation of nuclear power plants, but new research suggests it may not be as benign as portrayed.

Speeding up electronics to light frequencies

New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz domain.

Next scientific fashion could be designer nanocrystals

Three chemistry professors hope that their separate research trajectories will converge to create a new way of assembling what they call “designer atoms” into materials with a broad array of potentially useful properties and functions.

Data storage: Electrically enhanced recall

Random-access memory (RAM) is a fast electronic device used in computers to temporarily store data. Traditional RAM is based on the flow of electrical current for data processing. To make RAM faster, more energy efficient and capable of storing more information in a smaller volume, hardware developers are investigating RAM based on magnetic fields. Miniaturization of these devices, however, is hampered by thermal instabilities.
