Brain Wave Sensor

A tiny sensor that can detect magnetic field changes as small as 70 Femtoteslas — equivalent to the brain waves of a person daydreaming — has been demonstrated at the National Institute of Standards and Technology (NIST). The sensor could operate on a single AA battery and reduce the costs of non-invasive...

Hot Stuff

Bite into a hot pepper, and you'll feel the burn. But then, your tongue will go numb. It is that numbing process that scientists are studying in an effort to reduce post-surgery pain. Scientists have found that the chemical that makes chile peppers so hot (capsaicin) can actually relieve the pain of surgery. Capsaicin is being dripped...
