Using a two-step method, China has managed to nearly eradicate the species from two islands. The females were first sterilised using x-rays and then the males infected with a bacterium that prevented them from reproducing and carrying the disease. More on Nature.

HIV’s genome fully sequenced, points to virus first spreading to humans in 1900s
