Scientists have found that a mutation tied to Alzheimer's disrupts the production and quality of exosomes--tiny cell-made communication packets. Cells with the defective SORLA protein generate fewer exosomes and ones far less able to support nearby . ...

Ribosomes don't just make proteins--they can sense when something's wrong. When they collide, they send out stress signals that activate a molecule called ZAK. Researchers uncovered how ZAK recognizes these collisions and turns them into protective . ...

Scientists found that high-flavanol foods can prevent the decline in blood vessel function that occurs after prolonged sitting. Even physically fit men weren't protected unless they had consumed flavanols beforehand. A cocoa drink rich in these ...

Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even "unhealthy" ones, was strongly associated with greater ...

Scientists are uncovering what makes some carcinomas so resistant: their ability to change identity. Two new studies reveal crucial proteins and structures that could become targets for future therapies. These discoveries deepen understanding of how ...

Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely and malfunctioning. These disruptions resemble .. ...

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering repair within seconds. The mechanism works in both .. ...

A massive long-term study shows that Mediterranean and plant-based diets can help prevent chronic constipation in aging adults. Surprisingly, the benefits weren't explained by fiber alone. Western and inflammatory diets raised constipation risk, ...

Ultra-processed foods are rapidly becoming a global dietary staple, and new research links them to worsening health outcomes around the world. Scientists say only bold, coordinated policy action can counter corporate influence and shift food systems ...

Researchers have uncovered a surprising new role for the HSL protein: beyond breaking down fat, it also works inside the nucleus of fat cells to keep them functioning properly. When HSL is missing, fat tissue doesn't expand as expected-- instead, it ...
