Designer ‘Super-Smeller’ Mice Could Detect Explosives, Disease

Researchers have genetically engineered mice to be super smellers, and they could one day be used to help detect land mines, diagnosis diseases or make perfume with just the right amount of musk.

A team led by biologist Paul Feinstein of Hunter College in New York modified the genetic code of mouse embryos to produce mice with more neurons tuned to detect specific odors. Apart from homing in on targeted scents, the so-called MouSensor mice could also help answer basic questions about how
