Wayne State University researcher receives NSF CAREER Award to redesign wireless networking
The World Health Organization estimated in a 2009 report that each year more than 1.2 million people die of road traffic injuries. To combat this trend, the WHO encourages stricter enforcement of more comprehensive traffic laws. At WSU, one researcher is working on another emerging idea: helping vehicles avoid collisions. He is developing a central component of active safety -- wireless networks systems. (2011-05-25)

A tracking device that fits on the head of a pin
Prof. Koby Scheuer of Tel Aviv University has developed nano-sized optical gyroscopes that can fit on the head of a pin -- and, more usefully, on an average-sized computer chip -- without compromising the device's sensitivity. These gyroscopes will have the ability to pick up smaller rotation rates, delivering higher accuracy while maintaining smaller dimensions. (2010-10-05)

World of lights in the microcosmos

The other display could lead to self-powered electronic billboards. (2007-05-02)

A code to keep your fingerprints secure
It could soon become much harder for thieves to steal your digital identity. Unlike conventional biometrics that store the raw details of a fingerprint or iris scan, a new technique generates a unique code that cannot be used to reconstruct the original fingerprint or scan. An America company have created an algorithm that ensures the raw details need never be stored - making the code useless to anyone but the owner of the original body part. (2006-05-31)

MIT material puts new spin on electronics

Hello? Their phones have changed, but teenaged girls have not
Cellphones come in many shapes, colors and sizes now, but the teenaged girls who use them may not be very different than the young women who were learning how to use telephones more than 40 years ago. (2006-05-18)

New University of Toronto research a 'pore' excuse for engineering
A new study by chemists and engineers at the University of Toronto describes a nanoscale material they've created that could help satisfy society's never-ending hunger for smaller digital devices and cellphones, and could even lead to new methods for delivering medications via skin patches. (2006-03-21)

MIT researchers map city by cellphone
Researchers at MIT may not be able to hear your cellphone call, but they have found a way to see it. They mapped a city in real time by tracking tens of thousands of people traveling about carrying cellphones. Using anonymous cellphone data provided by the leading cellphone operator in Austria, A1/Mobilkom, the researchers developed the Mobile Landscapes project, creating electronic maps of cellphone use in the metropolitan area of Graz, Austria. (2005-09-14)

Carnegie Mellon researchers develop new software to detect viruses
New types of insidious programs are burrowing into a variety of embedded systems in cars and cellphones, creating all sorts of problems. Carnegie Mellon engineering researchers are combating the problem. (2005-03-10)

Researchers invent energy-saving computer chip
