A new study reveals that internalizing stress—especially feelings of hopelessness—may significantly speed up memory decline in older Chinese Americans. Surprisingly, factors like community support didn’t show the same impact. Researchers say cult…

Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with th…

A gut bacterium may be quietly fueling depression through an unexpected chemical twist. Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation—something strongly linked to …

Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain. By analyzing donated brain tissue with advanced genetic tools, the researc…

Engineers at Northwestern University have taken a striking leap toward merging machines with the human brain by printing artificial neurons that can actually communicate with real ones. These flexible, low-cost devices generate lifelike electrical sign…

Losing your sense of smell might signal Alzheimer’s far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in early…

A new study reveals that gut bacteria may play a key role in triggering ALS and frontotemporal dementia. Harmful sugars produced by these microbes can spark immune responses that damage the brain. This breakthrough explains why some genetically at-risk…

Scientists have uncovered a surprising new player in Alzheimer’s disease: a protein called CSE that helps produce tiny amounts of hydrogen sulfide gas in the brain. In experiments with genetically engineered mice, removing this protein led to memory …
