All living tissues give off photons as excited molecules shed excess energy. The phenomenon is so subtle – roughly a million times dimmer than the threshold of human vision – that researchers call it ultra-weak photon emission (UPE). Because the brain consumes an exceptionally high metabolic budget and is packed with photoactive compounds such as flavins and serotonin, scientists have …

By almost any measure, living through a once-in-a-century pandemic emergency that killed 7 million people — including 1.1 million in the U.S. alone — was a harrowing experience. Now, there’s new evidence suggesting our brains bear the scars of that ordeal. Living through the pandemic aged our brains faster — even among people who never became sick with COVID-19, according …

The devastation of the COVID-19 pandemic may have left a significant mark on our brains, even if we didn’t get sick. Fatal cases of COVID-19 look scarily like old age in the brain, and now, new research suggests that the mental, social, and financial stresses of the pandemic may have aged our brains as well. A team led by researchers …

Scientists watched the pandemic reshape hospitals, jobs, and politics, but a new set of brain scans hints that it also reshaped the organ inside our skulls. People who were never infected with SARS-CoV-2 showed brains that looked a few months older than expected. This suggests that merely living through lockdowns, uncertainty, and social upheaval left a subtle neurological …

Brain aging may have sped up during the pandemic, even in people who didn’t get sick from Covid, a new study suggests. Using brain scans from a very large database, British researchers determined that during the pandemic years of 2021 and 2022, people’s brains showed signs of aging, including shrinkage, according to the report published in Nature Communications. People who …

Dopamine is one of the most extensively studied chemical messengers in the human brain, and yet scientists are still figuring out how it works to accomplish so much. For years, the classic view has been that, when released, dopamine slowly diffuses through the brain like a chemical megaphone, broadcasting information far and wide to numerous target cells. Recently, however, that …

Found in everything from protein bars to energy drinks, erythritol has long been considered a safe alternative to sugar. But new research suggests this widely used sweetener may be quietly undermining one of the body’s most crucial protective barriers – with potentially serious consequences for heart health and stroke risk. A recent study from the University of Colorado suggests erythritol …

Summary: Researchers have identified ripple-type brain waves as key to how humans segment and store memories. By recording brain activity in epilepsy patients watching a TV episode, they found ripples marked event boundaries in the hippocampus while supporting information processing in cortical areas. This segmentation acts like punctuation, helping organize experiences into coherent episodes. The findings may inform therapies for …
