Genetically engineered mice can detect explosives 500 times better than normal mice

Scientists inserted a gene into odor sensing neurons in mice that could drastically increase their ability to smell TNT.

Mice have been genetically modified by scientists in hopes of increasing their ability to smell TNT with 500 times the sensitivity of normal mice. If successful, the mice could provide a cheap and effective way to sniff out landmines and other explosive devices that haunt nations all over the world.

An Implantable Biosensor Could Alert Doctors to Signs of Disease

silk biosensor

A biosensor made from silk and gold can pick up tiny signals from proteins and chemicals in the body.

Silk and gold, usually a pairing for the runways of Milan, are now the main ingredients for a new kind of implantable biosensor. Researchers at Tufts University have crafted a small antenna from liquid silk and micropatterned gold. The antenna is designed to spot specific proteins and chemicals in the body, and alert doctors wirelessly to signs of disease. Scientists say the implant could someday help patients with diabetes track their glucose levels without having to test themselves daily.
