Aerial drones are targeting a new enemy: malaria.
Four hundred feet above a Malaysian forest, a three-foot eBee drone hovers and takes pictures with a 16-megapixel camera every 10 to 20 seconds. But it's not gathering images of the mosquitoes that transmit malaria. Even today's best drones aren't capable of such a photographic marvel. Rather, the drone is looking at a changing landscape that holds clues to the disease's spread.

Baby Gammy might mean the end of Thailand's lucrative surrogacy business.
He's the child who was carried by a surrogate mom in Thailand-- and rejected by the Australian couple who had agreed to pay the mother $12,000. The reason: Prenatal testing showed that the baby, a twin, had Down syndrome.
Researchers have successfully decoded the genes of a 45,000-year-old man from Siberia. The results offer clues about early human life outside of Africa as well as how humans interacted with Neanderthals and other groups around at the time.
The complete set of genes is the oldest genome of its kind, according to Svante Pääbo, a director at the Max Planck Institute for Evolutionary Anthropology in Leipzig. "It's almost twice as old as the next oldest genome that has been sequenced."
