And finally, a study from the University of Michigan finds that if you talk to yourself in the third person by name, you’ll be less likely to cave in to tempting foods.
The availability of consumer DNA tests and databases has allowed long-hidden family secrets to be revealed, including mistaken paternity and unknown siblings.

When most of us think of genetic testing for health, we imagine tests to detect whether we’ve inherited genes that predispose us for cancer or other serious disease.

Experts explain how they hope to tap this knowledge.
