Laser sniffs out toxic gases from afar

Scientists have developed a way to sniff out tiny amounts of toxic gases—a whiff of nerve gas, for example, or a hint of a chemical spill—from up to one kilometer away.

New research facility houses largest plasma wind tunnel in the US

In hypersonic flight, an aircraft or spacecraft moves at least five times faster than the speed of sound—producing extreme heat that can push the craft beyond its physical limits. The difficulty and importance of protecting ...
