When cancer-driving proteins resist various treatments, Northwestern University scientists have uncovered a new solution. Don't fight them—throw them in the cellular trash. In a new study published in Nature Communications, ...

ChatGPT Health, a widely used consumer artificial intelligence (AI) tool that provides health guidance directly to the public—including advice about how urgently to seek medical care—may fail to direct users appropriately ...

So-called "yo-yo dieting" confers long-term health benefits, according to a new study by Ben-Gurion University of the Negev researchers. "Yo-yo dieting" is a pattern in which individuals lose weight through lifestyle interventions ...

Understanding the connection between behavior and brain cell activity is a major goal of neuroscience. To make progress, neuroscientists often choose simple, transparent lab animals because it's possible to see all their ...

A Dartmouth study challenges the conventional view that the amygdala—the two-sided structure deep in the brain involved in emotion, learning, and decision making—is simply the brain's primitive "fear center," reflexively ...

Subtle changes in how blood flows through the brain and how brain tissue uses oxygen may be closely linked to Alzheimer's disease risk, according to new research from the Mark and Mary Stevens Neuroimaging and Informatics ...

Never-before-seen 3D reconstructions of human liver tissue have been created at a cellular level. The details obtained by a team of UW Medicine and University of Washington engineers and physicians capture the spatial microstructure ...

Researchers with the Knight Initiative for Brain Resilience have modified a well-known immune protein to spark the growth of new neurons, ease brain inflammation, and improve cognition in old mice. The findings, published ...

In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.

Eating unhealthy foods early in life leaves lasting brain and feeding changes, but gut bacteria can help restore healthy eating, a new University College Cork (UCC) research study finds. A high-fat, high-sugar diet during ...

When we learn a new motor skill—whether mastering a piano passage or refining balance while walking—the brain must reorganize the circuits that control movement. For decades, this process of synaptic remodeling has been ...

A unique study imaging brain activity in children born with upper limb difference—for example, one hand—has shown the amazing ability of the brain to adapt to compensate and support their daily lives. The research, led ...
