The patients couldn't produce physical activity, as you or I would. But they could produce mental activity. They could use the brain as a kind of tablet, writing ''tennis'' on their supplementary motor area or ''navigation'' on their parahippocampal gyrus. That's the real genius of the European study: The mind can use the brain as a communication ...

Pam Tebow's story certainly is moving. But as a guide to making abortion decisions, it's misleading. Doctors are right to worry about continuing pregnancies like hers. Placental abruption has killed thousands of women and fetuses. No doubt some of these women trusted in God and said no to abortion, as she did. But they didn't end up with ...

In more and more places, machines are running the world. On stock exchanges, high-speed computers armed with trading algorithms and superior pattern recognition are thrashing human competitors. Airline autopilots have become so reliable that human pilots can check out. In cars, software is beginning to assume responsibility for steering, braking, ...

The bombing of the CIA base, like the November massacre at Fort Hood, Texas, was an act of war. It was also espionage. But it wasn't terrorism. Terrorism targets civilians. The CIA officers killed at the Afghan base, like the soldiers shot down at Fort Hood, were not civilians. They were running a war. More here.

Now the Taliban seem to have come up with a new strategy: using the drones' human intelligence networks to infiltrate the program and kill the people who run it. Last week, a suicide bomber blew up seven CIA officers at a U.S. military base in Afghanistan near the Pakistan border. It looked like just another insurgent attack. But it was more than ...

You'll have to start showing your gonads when you go to the airport. You won't have to show them to the people standing next to you. But you'll have to show them to the Transportation Security Administration. You'll stand in front of a machine that sees through your clothes. It will capture every contour of your body and relay this picture to a ...

According to a photo posted by ABC News, the bomb allegedly smuggled on board Northwest Flight 253 last week was a packet of powder sewn into the bomber's underwear. Note the packet's location: right in the crotch, where a TSA pat-down is least likely to catch you. How do you find a nonmetallic bomb tucked into such a private place? By ...

After trillions of dollars, decades of debate, and months of legislative haggling, the fate of health care in the United States is coming down to an old-fashioned moral issue. Pro-lifers and pro-choicers are fighting over insurance coverage of abortions. Each camp seems capable of killing the legislation pending in Congress. Abortion, we're told, ...

You've heard of planes that vanished into thin air? Here's a truer, scarier story: On Oct. 21, 2009, two pilots flying from San Diego to Minneapolis vanished into cyberspace. Their plane was fine. Ground controllers tracked it the whole time. The passengers and flight attendants in the main cabin noticed nothing unusual. And the pilots' bodies ...

Today's highlights in science, medicine, and technology: 1. Adultery and texting. Tiger Woods isn't the first guy to cheat on his wife or get caught by his own text messages. Look at Kwame Kilpatrick and John Ensign. And for poetic value, don't forget Mark Sanford. Wise up, cheaters: Your tryst is soon over, but your text messages are ...
