Biologists claim that humans can perceive and distinguish a trillion different odours, but little is known about the underlying chemical processes involved. Researchers from The City College of New York, Duke University and Hebrew University have found an unexpected chemical strategy employed by the mammalian nose to detect chemicals known as aldehydes. The current study, published in the journal ACS Chemical Biology, found that some of … Continue reading Chemists discover new mode of detection in nose for common class of odours.
