Physicists push for underground testing facility

Pran Nath, the Matthews Distinguished Professor of Physics at Northeastern University, is among a group of leading theoretical physicists who have asked the Department of Energy to develop a large underground neutrino facility to maintain U.S. leadership in the frontier of particle physics. We asked Nath to explain the facility and its value.

Accidental Kakapo Death Lowers Population of Rare, Flightless Parrots to 127 Birds

The death of an adult female kakapo ( Strigops habroptila ) on New Zealand’s Anchor Island this past weekend brings the population of these rare flightless parrots down to just 127 birds. The late kakapo, known as Sandra, was killed when her transmitter harness got entangled in a tree. All kakapos are outfitted with transmitters to help rangers in the Kakapo Recovery program keep track of the birds.

Middle East Trails Again in Green Energy Growth

By Maha El Dahan and Daniel Fineren ABU DHABI/DUBAI (Reuters) - Talk of a Middle Eastern green energy boom is likely to prove no more than a mirage with little hope of the region saving clean technology companies from the shrinking project pools of Europe.

Magnetic random-access memory based on new spin transfer technology achieves higher storage density

Solid-state memory is seeing an increase in demand due to the emergence of portable devices such as tablet computers and smart phones. Spin-transfer torque magnetoresistive random-access memory (STT-MRAM) is a new type of solid-state memory that uses electrical currents to read and write data that are stored on magnetic moment of electrons. Rachid Sbiaa and co-workers at the A*STAR Data Storage Institute have now enhanced the storage density of STT-MRAM by packing multiple bits of information into each of its memory cells.

Researchers efficiently couple light from a plane wave into a surface plasmon mode

Researchers from the NIST Center for Nanoscale Science and Technology have made a grating coupler that transmits over 45 % of the incident optical energy from a plane wave into a single surface plasmon polariton (SPP) mode propagating on a flat gold surface, an order-of-magnitude increase over any SPP grating coupler reported to date.

Illusion Contest Offers Mind-Warping Visions (preview)

Jordan Suchow came to three rapid-fire conclusions as he watched his Macintosh laptop plummet toward the floor. First, in approximately 300 milliseconds he was going to be in a heap of trouble--the machine had been given to him by his thesis adviser, George Alvarez of Harvard University.

Tsunami Debris and North America: Is the Tail Wagging the Dog?

Recent weeks have seen a spate of news articles (three examples here , here , and here ) claiming that wreckage from the March 2011 Japanese tsunami has started arriving on the west coast of North America. Is that likely?
