As scientists can see more and more into the brain through imaging, they are learning that some teens are hard-wired to be more likely to use drugs, including alcohol, and become addicted.
Researchers have found diminished activity in the part of the brain that deals with impulse control. Teens with ADHD, which comes from a different part of the brain, also have difficulty inhibiting behavior.
Brain research is important and comes at a time when the number of pregnant women addicted to opiates such as Oxycodone has increased five-fold in the last decade, so their babies are born addicted as well.
The newborns have severe withdrawals symptoms and could suffer long-term brain damage. Neurobiologists are working on vaccines for drug addiction that show promise.
If you're a women and you're obese, a new study finds you will be faced with all sorts of discrimination in the workplace.
It is less likely that you will be hired, more likely that you'll make a lower starting salary, and less likely that you'll be in a leadership role. Of course research is showing more and more that obesity is tied to genetics.
And finally, do you want a better brain? Then put down the crossword puzzles and go for a jog. Scientists have now found that exercise appears to build a brain tissue that resists shrinkage and helps cognitive flexibility. Exercise, they say, does more to help thinking than thinking does.
