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.

Superconductors that work by themselves: Scientists discover new possibilities in cryoelectronics

Scientists have experimentally demonstrated a new type of superconducting element -- named the phi-Josephson junction. Implemented in cryogenic devices, this element will make superconducting electronic circuits work practically "by themselves" and improve functionality.

NASA Offers High School Girls A Chance To Jump-Start Their Future

NASA is offering high school junior girls from across the United States an opportunity to jump-start their future by participating in the Women In STEM High School (WISH) Aerospace Scholars program for 2013.
