Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to people by smelling the carbon dioxide we exhale. This is the outcome of a new study.
Some diseases can modify animal odors in subtle ways. In one study, it has been shown that infection with avian influenza (AIV) alters fecal odors in mallards. This could lead to a new detection method to root out infected birds.
Researchers have developed a chemical 'smell' which they have called “olfactory white”. Olfactory white is a mixture of many different smelly compounds. The compound has the remarkable potential to combat other strong odors.
