A new study from Michigan State University (MSU) researchers reveals that honeybees can detect lung cancer biomarkers in a person’s breath. The insects can also distinguish between healthy and lung cancer cells just by smelling a cell culture. Unlike humans, honeybees don’t have a nose. They smell with their antennae, which function similarly to vertebrate noses. Molecules in the air enter tiny pores in their antennae and interact with receptors on olfactory neurons. These neurons are sensitive to very small concentrations and a broad range of different molecules. “When a honeybee smells anyth…
