Brain Scans Predict Women's Eating and Sexual Behavior
By measuring how women's brains respond to images of food and sex, researchers may be able to predict whether the women are set for weight gain or sexual activity in the months ahead.
What's the Latest Development?
Dartmouth University researchers have found a way to accurately predict the eating and sexual behavior of women using functional magnetic resonance brain scans. In an experiment, the brains of 48 women were scanned while the women were shown pictures of food, animals, nature scenes and people in sexual and nonsexual activities. "Women whose brains demonstrated greater activity in response to pictures of food were more likely to have gained weight six months later than those whose brains did not respond to the pictures."
What's the Big Idea?
Women who described themselves has having higher levels of sexual desires also responded more strongly to the sexual photos shown during the experiment. "Brain activity was also significantly higher in the 22 women who reported having sex in the following six months, compared with the 26 who did not." Lead author of the study and professor of psychology at Brown, Kathryn E. Demos said, "What’s novel here is that we can actually make predictions about behavior based on brain activity. ... These individual differences could give us clues to work on in developing treatments."

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.

A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
