The Air Force is pushing to weaponize space. Programs are in the works to 1) make radio waves lethal, 2) build planes that "strike from halfway around the world in 45 minutes," 3) use blimps and mirrors to aim lasers at earth targets, and 4) fire heavy-element cylinders "striking at speeds of about 7,200 miles an hour with the force of a small nuclear weapon."

U.S. military associations are fighting restrictions on women in combat. A new bill would tighten the official ban. A retired general says it's too hard to enforce the ban strictly, since troops can now be attacked anywhere.

Scientists are debating  the evolutionary logic of the femaleorgasm. Some think it motivates women to have sex; others think it improves sperm retention; others think it's "phasing out."

A CIA flying drone killed an al-Qaida operative in Pakistan. The drone was "operated from a secret base hundreds of miles" away. The Air Force will buy 59 more drones over the next five years and arm them with up to 3,000 pounds of precision-guided munitions.

Major drugstores will movemore than 100 cold medicines behind the counter to help stop methamphetamine production. The medicines include Advil, Benadryl, Contac, Claritin, Motrin, Sudafed, and Tylenol products. The companies want uniform policies because they can't keep track of new state laws on these products.
