Deborah Anderson is one of this year’s winners of the famous Ig Nobel prize (the annual award given by the Annals of Improbable Research magazine towards unusual scientific achievements). Anderson is an obstetrics and gynecology professor at Boston University’s School of Medicine. She and her team proved that Coca-Cola acts as a spermicide. Also, surprisingly enough, they have found that Diet Coke worked even better. Of course, Coke is still not recommended as a birth control method.
