One of the best ways to figure out how parts of the brain work is to study people who have damage in those specific areas. Take a patient known as SM, a middle-aged woman with a rare condition called Urbach-Wiethe disease that has damaged the amygdala on both sides of her brain.A few years ago, SM told Justin Feinstein, then a graduate student at the University of Iowa in Iowa City, that she’d never felt fear, even when she’d been confronted by a knife-wielding assailant.
Feinstein put her claim to the test. His group had SM handle a snake, took her on a tour of a haunted house and showed her scenes from scary movies like The Shining. SM was unfazed.
But another University of Iowa researcher, neuroscientist John Wemmie, had a different test for SM: breathing carbon dioxide. In people without brain damage, exposure to high levels of carbon dioxide evokes fear and a hunger for air. In some, it can even set off a panic attack.

Today in hackings originating from China: The New York Times. The hacking incident began after The Times started working on this story about Chinese Prime Minister Wen Jiabao’s fortune. Every Times employee had their corporate password stolen, and 53 employees had their personal computers infiltrated, mostly outside of the office. So yeah, kind of a big story.
Jeebus…read the article. This is a big story.
