Aedes aegypti is the dog of the mosquito world. It acts as if it's man's best friend.

"It's been with us for a long time, probably for at least 5,000 years when we started keeping water next to our homes [ideal for laying eggs] and it's adapted to people," says Marten Edwards, an entomologist at Muhlenberg College in Allentown, Pa. "It loves us. It loves our cities. It loves our blood. It functions very well with us."

For years, Thai police have been trying to track down a master passport forger known only as "The Doctor."

Former Los Angeles County Sheriff Lee Baca, who has been embroiled in a scandal involving reports of prisoner abuse and an alleged conspiracy to cover it up, has pleaded guilty to making false statements, the Department of Justice announced Wednesday.

The single count against him relates to statements made regarding a federal investigation into corruption and violence at LA County jails. Baca has confessed to lying multiple times when he said he did not know about the actions of those within his department. He was still serving as sheriff at the time.
