The bottom of the ocean is cold, dark and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At the deepest point, the pressure of 36,200 feet of seawater is greater than the weight of an elephant on every square inch of your body. Yet Earth’s deepest places are home to life uniquely suited to these challenging conditions. Scientists have studied how the...

It is late at night. You are alone and wandering empty streets in search of your parked car when you hear footsteps creeping up from behind. Your heart pounds, your blood pressure skyrockets. Goose bumps appear on your arms, sweat on your palms. Your stomach knots and your muscles coil, ready to sprint or fight. Now imagine the same scene, but without any of the body’s innate responses to an...

During traumatic periods and their aftermath, our brains can fall into habitual ways of thinking that may be helpful in the short run but become maladaptive years later. For the brain to readjust to new situations later in life, it needs to be restored to the malleable state it was in when the habits first formed. That is exactly what Gül Dölen, a neuroscientist and psychiatric researcher at the...

Recent research into the true causes of depression is finding clues in other neurotransmitters and the realization that the brain is much more...
