Divers who hold breath for several minutes elevate a marker for brain damage

Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage, according to a new study from the Journal of Applied Physiology. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term.

Walk, don't drive! community promotion of physical activity has two-fold benefit

About half of the car trips in the U.S. are less than five miles - a distance easily navigated by walking or cycling. Reducing short-distance car trips has many benefits - it decreases car accidents, has positive benefits for the environment and increases physical health and activity, says communication professor Edward Maibach of George Mason University. An expert in climate change communication research, Maibach says that community leaders should make promotion of physical activity a priority.
