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 …

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which sen…
