According to the Mayo Clinic, stress can cause a number of health issues including high blood pressure, heart disease, obesity and diabetes. A new University of Georgia, Athens (UGA) study is being funded by the National Institutes of Health (NIH) to show how stress affects children’s immune system. This $2.3 million, Director’s New Innovator Award, will allow researchers to correlate acute stress with how children’s immune systems respond to vaccination.Read More

A pioneering new study at Ohio State University found a link between chronic stress and short-term memory issues. In the study, mice were subjected to repeated visits from an aggressive, larger intruder mouse. Researchers found that the mice repeatedly exposed to the intruder had more difficulty recalling where the escape hole was in a maze they’d mastered prior to the stressful period, compared to mice that had not been stressed.

In a potentially dangerous situation, many animals release stress hormones into the body to prepare the animal for raw survival. Sometimes these evoke defense mechanisms and sometimes they assist in fleeing from danger, hence the idea of a “fight or flight” response. Now, research at the University of Michigan, Ann Arbor shows that tadpoles instead choose a third option: physical transformation.
