Scientists at the University of California at San Diego and the nearby Veterans Affairs Medical Healthcare System in La Jolla recently concluded that magnetic nanoparticles may be hazardous to your health.
IBM uses 'racetrack' to advance memory storage
News & Analysis  
4/11/2007   Post a comment
IBM recently demonstrated the ability to move magnetic domains along a nanowire memory called a racetrack, thereby promising to obsolete hard drives and other nonvolatile memories, such as flash, MRAM and PRAM.
Nanogenerator harvests power from waves
News & Analysis  
4/9/2007   Post a comment
A nanogenerator devised in a Georgia Tech lab havests energy from vibrations or ultrasound to move a piezoelectric nanowire array that responds by outputting voltage, advancing efforts to power devices without batteries.
M/A-COM qualifies MEMS oscillator for smart munitions
News & Analysis  
4/9/2007   Post a comment
The world's first design win for microelectromechanical-system oscillators is a high-reliability military application--a wireless transmitter that streams real-time telemetry data back from smart munitions to remotely guide them to their target. Discera Inc. will announce today that M/A-COM (Lowell, Mass.) will use its MOS-1 MEMS oscillator in a wireless transmitter built for smart munitions. During testing, M/A-COM removed some warheads, allowing munitions to be retrieved after impact--and Di
Power Sources : Power-harvesting technology enters phase two
Product News  
4/9/2007   Post a comment
Many years of innovation in power harvesting have brought some maturity to solar, wind, geothermal and even wave technologies. Solar panels have become ubiquitous, General Electric has mastered the megawatt-caliber wind and geothermal turbine, and younger companies like Finavera Renewables have harnessed ocean-wave motion with electrical- generator technologies.

Nanotech researchers report advances
News & Analysis

Several nanotechology advances have been reported, including a nanoneedle invisibility cloak, the brightest nanoparticle and the highest temperature superconductor.
First bandpass filter in 'terahertz gap' demonstrated
News & Analysis  
4/2/2007   Post a comment
Scientists at the University of Utah have demonstrated the world's first bandpass filter to employ an unused gap in the electromagnetic spectrum. Working in the terahertz gap, which is centered on 1 trillion cycles/second, the scientists have harnessed surface plasmon polaritons to realize one of the three essential components required for communications systems.
