Superconducting Chips To Become Reality
Most chemical elements become superconducting at low temperatures or high pressures, but until now, copper, silver, gold, and the semiconductor germanium, for example, have all refused superconductivity. Scientists at the Forschungszentrum Dresden-Rossendorf (FZD) research center…

World’s Most Complex Silicon Phased-array Chip Developed
electrical engineers have developed the world’s most complex “phased array” — or radio frequency integrated circuit. This DARPA-funded advance is expected to find its way into U.S. defense satellite communication and radar systems. In addition,…

Storing Data On Atomic Roundabouts
There are right-handed and left-handed yoghurts, right-handed and left-handed snail shells, and right-handed and (occasionally) left-handed screws. Scientists at the University of Bonn have now demonstrated the existence of right-handed and left-handed “magnetic vortices”. Through…

Ancients Engineered Sophisticated Machines
Move over, Archimedes. A researcher at Harvard University is finding that ancient Greek craftsmen were able to engineer sophisticated machines without necessarily understanding the mathematical theory behind their construction. Recent analysis of technical treatises and…

Fight Phishing Attacks With Phishing Tactics
Early findings by Carnegie Mellon University researchers suggest that people who are suckered by a spoof email into visiting a counterfeit Web site are also people who are ready to learn their lesson about “phishing”…

Any Digital Camera Can Take Multibillion-pixel Shots With New Device
Researchers at Carnegie Mellon University, in collaboration with scientists at NASA’s Ames Research Center, have built a low-cost robotic device that enables any digital camera to produce breathtaking gigapixel (billions of pixels) panoramas, called GigaPans.…
