A new study finds that some people really are “mosquito magnets” and it probably has to do with the way they smell.
Scientists used "gene-editing" technology to disable the light receptors in the eyes of the aedes aegypti mosquito, an invasive species in much of the world that can carry diseases. UC Santa Barbara professor Craig Montell talks about the research that made mosquitoes unable to detect humans.
They asked 64 volunteers from the university and nearby to wear nylon stockings around their forearms to pick up their skin smells. The stockings were put in separate traps at the end of a long tube, then dozens of mosquitos were released. Scientists held a round-robin tournament and ended up with a striking gap: The biggest mosquito magnet was around 100 times more attractive to the mosquitoes than the last place finisher.
