With summer waiting in the wings, we’re getting excited to don some short pants and sleeveless tops. Unfortunately, all that bare skin often brings with it less-than-savory mosquito bites. However, getting those suckers to bugger off doesn’t have to mean dousing yourself in chemicals or forgoing style. A Cornell University scientist from Kenya and a Gambian designer have developed a stylish purple-and-gold hooded bodysuit steeped with insecticides at the nano level. Designed to repel mosquitoes infected with malaria, the suit can be worn all day, and unlike spray-on repellants that disappear within hours, these nano-particles are built to stick around.
