Science Daily  December 8, 2020 A team of researchers in the US (University of Washington, University Maryland) used antennae from the Manduca sexta hawkmoth for Smellicopter. One scent molecule in a moth antenna can trigger lots of cellular responses amplifying chemical signals. This process is super-efficient, specific, and fast. Researchers placed moths in the fridge to anesthetize them before removing an antenna. Once separated from the live moth, the antenna stays biologically and chemically active for up to four hours which can be extended by storing antennae in the fridge. In tests the moth antenna reacted more quickly and took […]
