We're nowhere near ready to hand over the core of our democratic process-voting-to electronic systems.
Hybrid devices that are part machine, part living cells, offer new hope to patients for whom purely artificial treatments like dialysis aren't good enough.
Despite staunch opposition from the computer science community, ATM-style electronic voting may offer the best hope for escaping the mess inflicted by paper-based balloting systems.
Hewlett-Packard is betting that it can build computers whose functionality rests on the workings of individual molecules. It's blue-sky research, but if it works, it will push computing far beyond the limits of silicon.
The 7E7 could set new efficiency standards, thanks to lightweight materials, smarter sensors, and a streamlined design process. But can it pull Boeing out of a market nosedive and revitalize struggling airlines?
Straight from the Lab: Technology's First Draft
New transistors made from oxide semiconductors-rather than the usual silicon-are yielding transparent electronics.
Electronic seals and tracking efforts boost cargo security.
Massachusetts General Hospital doctors lead a tour of what they hope will be the world's most efficient operating room.
