The unpredictable nature of life during the coronavirus pandemic is particularly challenging for many people. Not everyone can cope equally well with the uncertainty and loss of control. Research has shown that while a large segment of the population turns out to be resilient in times of stress and potentially traumatic events, others are less robust and develop stress-related illnesses.

The rate of suicide among post-9/11 military veterans has been rising for nearly a decade. While there are a number of factors associated with suicide, veterans have unique experiences that may contribute to them thinking about killing themselves. Compared to their civilian peers, veterans are more likely to report having experienced traumatic adverse childhood experiences (ACEs) such as physical and […]

In their day jobs, research psychologists don’t typically need safety goggles, much less pith helmets or Indiana Jones bullwhips. There’s no rappelling into caves to uncover buried scrolls, no prowling the ocean floor in spherical subs, no tuning of immense, underground magnets in the hunt for ghostly subatomic particles. Still, psychologists do occasionally excavate the habits of lost civilizations. In […]

The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today in Nature Methods. The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever […]

The brain has a knack for safekeeping our most treasured memories, from a first kiss to a child’s birth. In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain maintain these kinds of long-term memories. By observing the activity of nerve cells of the brain, called neurons, that were extracted […]

Working with mouse and human tissue, Johns Hopkins Medicine researchers report new evidence that a protein pumped out of some — but not all — populations of “helper” cells in the brain, called astrocytes, plays a specific role in directing the formation of connections among neurons needed for learning and forming new memories. Using mice genetically engineered and bred with […]

As we age, our eyes lose their ability to focus up close. It’s a condition called presbyopia, and it’s both extremely common and relatively easy to fix, with solutions like reading glasses, bifocals, or progressive lenses. Another common correction, called monovision, solves the problem with different lenses in each eye, one that focuses nearby, the other that focuses far away. […]

Doctors have known for years that some patients who become unresponsive after a severe brain injury nonetheless retain a “covert consciousness,” a degree of cognitive function that is important to recovery but is not detectable by standard bedside exams. As a result, a profound uncertainty often haunts the wrenching decisions that families must make when an unresponsive loved one needs […]
