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 ...

Scientists have uncovered how leukemia cells manage to escape one of the most commonly used treatments. Over time, these cancer cells subtly change the shape of their mitochondria to avoid dying when the drug tries to kill them. By identifying the .. ...

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage ...

Researchers discovered that raising the protein Sox9 can help the brain's astrocytes clear out toxic plaque buildup linked to Alzheimer's. In mouse models that already showed memory problems, activating these cells improved cognitive performance. The ...

Scientists discovered that lowering a specific molecule helps microglia switch into a protective state that quiets brain inflammation in Alzheimer's. A small group of these cells seems to have an outsized ability to keep the brain healthier. When a . ...
