African trypanosomiasis is making an unwelcome comeback. But unlike other returning diseases, this one has a drug treatment—eflornithine—that disappeared from the market when it failed to cure cancer. Yet like Viagra's origin from a curious side effect in a clinical trial, so too was eflornithine reborn. "When it was discovered that it removes mustaches in women, it suddenly had a market: western women with mustaches," says Morten Rostrup, president of the international council for M
