A review of more than 200 studies reveals that olfactory receptors--proteins that bind to odors that aid the sense of smell--perform a wide range of mostly unknown functions outside the nose. The function of extra-nasal olfactory receptors has the potential to be used in the diagnosis and treatment of health conditions such as cancer.

The device, the NanoVelcro Chip, works by "grabbing" circulating tumor cells, which break away from tumors and travel through the bloodstream, looking … Continue reading New ‘blood biopsies’ with experimental device may improve cancer diagnosis and follow-up
