| Malaria Mosquito |
Dr. Fredros Okumu, the head of the research project at Tanzania's Ifakara Health Institute, discovered that the stinky smell of a human foot attracted many mosquitoes and 95% of those mosquitoes were poisoned by the said foot pungent odor.
He learned this experiment from Dr. Bart Knols, a Dutch scientist who made the first discovery by standing in a dark room naked and found out that mosquitoes bit mainly his feet, which were emitting a stinky odor.
