UCLA life scientists have identified for the first time a particular gene’s link to optimism, self-esteem and “mastery,” the belief that one has control over one’s own life — three critical psychological resources for coping well with stress and depression.

“I have been looking for this gene for a few years, and it is not the gene I expected,” said Shelley E. Taylor, a distinguished professor of psychology at UCLA and senior author of the new research. “I knew there had to be a gene for these psychological resources.” (more…)

Knowing the right way to handle stress in the classroom and on the sports field can make the difference between success and failure for the millions of students going back to school this fall, new University of Chicago research shows.

“We found that cortisol, a hormone released in response to stress, can either be tied to a student’s poor performance on a math test or contribute to success, depending on the frame of mind of the student going into the test,” said Sian Beilock, associate professor in psychology and one of the nation’s leading experts on poor performance by otherwise talented people.

EAST LANSING, Mich. — While recent studies have shown long-term exposure to estrogen can be a danger to women – overturning physicians’ long-held beliefs that the hormone was good for their patients’ hearts – the process by which estrogen induces high blood pressure was unclear.

In a new study, Michigan State University researchers found long-term estrogen exposure generates excessive levels of the compound superoxide, which causes stress in the body. The buildup of this compound occurs in an area of the brain that is crucial to regulating blood pressure, suggesting that the estrogen-induced buildup causes increased blood pressure. (more…)
