Lab-Grown Smell Receptors Could Pave the Way for Artificial Noses

Anosmiacs, rejoice. MIT’s biological engineers, moving us ever closer to our transhuman future, have mass-produced lab-grown smell receptors — a breakthrough that will greatly increase their ability to study the way these proteins react to odor. Their goal is not only to unlock the secrets of olfaction, but also to… » 10/01/08 7:00am 10/01/08 7:00am
