...amygdalae, a pair of almond-shaped brain regions deep within each temporal lobe that control fear and the processing of emotion. It's your amygdalae that keep you from getting so close to another person that he could easily reach out, gouge an eye, and then drag your woman off by her hair. (See the top 10 scientific discoveries...
...what happens if you disable the amygdalae? This is not something you could (ethically) do to a research subject, but scientists have been studying a 42-year-old woman who has such severe damage to her amygdalae - due to a rare genetic condition called Urbach-Wiethe disease, which causes calcification in the temporal lobes - that they have stopped functioning. The patient's identity isn't public, but neuroscientists call her SM, and a new paper in the journal Nature Neuroscience reports the results of experiments judging her conception of personal space...
...team of scientists from Caltech put SM through a series of tests in which they asked her to indicate the position at which she became uncomfortable as another woman, a researcher, approached her. SM's preferred personal distance was 1.1 ft. (0.34 m), about half the preferred distance (2 ft., or 0.64 m) of a group of comparison subjects. At 1 ft., you can easily discern whether someone showered after the gym - although in the lab experiment, the Caltech researchers made sure the experimenter was well-scrubbed and had just chewed gum before interacting with SM.

...nothing like the opposite sex to curb our appetites, at least when we're single. In a study to be published in the October issue of Appetite, researchers at Montreal's McGill University secretly observed 460 college students eating in the campus cafeterias. They found that when a woman was with a man, she ate about 100 calories less than when she was with a woman. The more men present in larger eating groups, the fewer calories a woman had on her tray. Women ate roughly 100 fewer calories for each man at the table. But there was no such...
...study's author Meredith Young, a cognitive psychologist, says the social comfort of a same-sex lunch partner probably makes a difference - but evolutionary instincts are also at play. The women are using food as a signal of attractiveness. "In past studies, when you compare the exact same woman either eating a meatball sub or a dainty salad, people find the salad eater more alluring and more desirable as a friend," she says. Young thinks that men, on the other hand, are probably focused on spending more money on the food instead of eating it, because evolutionary biology says that...
