    Scientists in Tanzania have a plan to foil malaria-infected mosquitoes without fancy equipmen

    Malaria kills an estimated 800,000 people worldwide every year. But it might have met its match in an unlikely team that includes Bill Gates, and a whole lot of stinky feet. Here, a brief guide:

    What does foot odor have to do with malaria?
    People might find smelly shoes and socks disgusting, but mosquitoes find them irresistible. Studies have found that mosquitoes are attracted to dirty socks up to four times as much as they are to humans. In an experiment in three Tanzanian village where the locals get up to 350 bites a year from malaria-infected mosquitoes, scientists are going to test traps using stinky socks as bait.

    How exactly do the traps work?
    They're just wooden boxes that look like commercial beehives. The scientists plan to put smelly socks worn by adults in some. They'll also try a human-odor bait concocted by the researchers using simple chemicals, such as lactic acid, ammonia, and propionic acid, to mimic a distinctly human smell. Once the mosquitoes fly into the traps, they'll be killed using poisons, which do them in quickly, or by a fungus that infects the bugs and kills them over the course of several days. By using various formulae, the researchers will be able to tell which design catches the most bugs.

    Where does Bill Gates come in?
    The research team, led by entomoligist Fredros Okumu of Tanzania's Ifakara Health Institute, has won a grant from Grand Challenges Canada and the Bill & Melinda Gates Foundation to try out their contraptions. If Okumu's design works, he hopes his box-like traps can be cheaply produced all over East Africa, giving small, remote towns a way to prevent the spread of malaria using resources they already have. "It's a bold idea," says Peter A. Singer, a physician who heads Grand Challenges Canada, a government development agency. "Who would have thought there was a life-saving technology working in your laundry basket?"

    May be yes or no.
