NASA's Radar Found 4 Men Trapped in Rubble in Nepal By Their Heartbeats

A couple years ago, NASA and DHS unveiled a portable radar unit based on technology used to monitor spacecraft. This radar unit, though, would be used closer to home—to find people burried under rubble. In the first real-world demonstration of its use, the device helped save 4 men trapped under earthquake rubble in… »5/06/15 11:35am

Radar-Enabled Light Bulbs Automatically Detect When the Elderly Fall

Even when the elderly are being tended to by a caregiver, it's almost impossible to keep an eye on them 100 percent of the time. So a Japanese company has developed a pair of LED light bulbs featuring built-in laser-based radar to track the movements of someone in its vicinity, and automatically send alerts when they… »11/11/14 12:43pm

Mysterious Radar Cloud Over the Midwest Was Actually... Butterflies

Can Radar and RFID Stop Drivers From Killing Cyclists?

Last month, London reached a grim milestone: Six cyclists were killed within 14 days, sparking a massive "die-in" protest. London isn't alone; 176 cyclists or pedestrians were killed in NYC last year. The rapidly rising death toll is spurring a race to build a technology to warn drivers before they hit someone on foot… »12/31/13 2:30pm

Dolphins Inspire a New Kind of Radar That Detects Hidden Electronics
