CHIP-SCALE MAGNETIC SENSOR DRAWS ON MINI CLOCK DESIGN, December 29
A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas - a million times weaker than the Earth's magnetic field - has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the Dec. 27 issue of Applied Physics Letters, the device can be powered with batteries and is about 100 times smaller than current atom-based sensors with similar sensitivities, which typically weigh several kilograms (about 6 pounds).

MAJOR ADVANCE MADE IN TRANSPARENT ELECTRONICS, December 29
Researchers at Oregon State University and Hewlett Packard have reported their first example of an entirely new class of materials which could be used to make transparent transistors that are inexpensive, stable, and environmentally benign. This could lead to new industries and a broad range of new consumer products, scientists say.
The possibilities include electronic devices produced so cheaply they could almost be one-time "throw away" products, better large-area electronics such as flat panel screens, or flexible electronics that could be folded up for ease of transport.
