Is the National Security Agency collecting cellphone tracking information on millions of Americans?
After a Senate Intelligence Committee hearing, we still can't be sure. Sen. Ron Wyden, D-Ore., has been trying to get intelligence officials to confirm or deny the existence or nonexistence of such a program.

One thing you can say about the diminutive speckled sea louse: it's always on time.
Scientists studying the tiny crustacean, a marine cousin of the wood-louse, found that it runs not one, but two internal clocks. Not only does the creature have a circadian rhythm, or so called "body clock" like most land-dwelling animals, including humans, but it also has a circatidal clock that follows the 12.4-hour cycle of the tide.
But the study also finds that strikes carried out by unmanned aerial vehicles cause fewer civilian casualties than other kinds of combat and that those deaths don't appear to be linked to further violence against U.S. forces and allies.
