Building ultralow power wireless networks

August 29, 2012 4:16 am | News | Comments

Engineering researchers at the University of Arkansas have received funding from the National Science Foundation to create distortion-tolerant communications for wireless networks that use very little power. The research will improve wireless sensors deployed in remote areas where these systems must rely on batteries or energy-harvesting devices for power.

Magnetic vortex reveals key to spintronic speed limit

August 28, 2012 12:08 pm | News | Comments

Spintronic devices use electron spin, a subtle quantum characteristic, to write and read information. But to mobilize this emerging technology, scientists must understand exactly how to manipulate spin as a reliable carrier of computer code. Now, scientists at Brookhaven National Laboratory have precisely measured a key parameter of electron interactions called non-adiabatic spin torque that is essential to the future development of spintronic devices.

Stanford researchers discover the 'anternet'

August 27, 2012 4:27 am | News | Comments

A collaboration between a Stanford University ant biologist and a computer scientist has revealed that the behavior of harvester ant as they forage for food mirrors the protocols that control traffic on the Internet.

How to feed data-hungry mobile devices

August 23, 2012 6:13 am | News | Comments

Researchers from Rice University unveiled a new multi-antenna technology that could help wireless providers keep pace with the voracious demands of data-hungry smartphones and tablets. The technology aims to dramatically increase network capacity by allowing cell towers to simultaneously beam signals to more than a dozen customers on the same frequency.

Shelley, Stanford's robotic racecar, hits the track

August 14, 2012 8:37 am | by Bjorn Carey | News | Comments

Only a few decals and antennas set Stanford University’s white Audi TTS apart from any other Audi coupe.
