Scientists have uncovered how too much sunlight can flip a hidden switch inside skin cells that makes inflammation spiral out of control and increases the risk of cancer. Their research reveals that UV radiation breaks down a protective protein ...

MIT scientists found that what we see is strongly influenced by how alert or active we are. Parts of the brain responsible for planning and control send specialized signals that either boost or quiet visual details. These areas seem to balance each . ...

Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified molecules that influence how long memories persist. ...

Scientists found that RSV infection early in life can set the stage for childhood asthma, particularly in kids already genetically prone to allergies. The virus appears to skew the developing immune system toward exaggerated responses to everyday ...

Researchers have found that ongoing thyroid hormone imbalance in pregnancy may be linked to higher autism risk in children. Treated thyroid disorders did not show the same effect. The longer the imbalance lasted across trimesters, the more the risk . ...

Researchers studying thousands of canine genomes discovered that wolf DNA is still present in most dog breeds. This ancient genetic influence shows up in traits like body size, behavior, and environmental resilience. Even dogs bred far from wolves, . ...

Millions face Medicare decisions each year, but many don't take advantage of tools that can save them money and stress. Insurance marketing often overshadows unbiased options like SHIP, leaving people unaware of better choices. Comparing real costs- ...

Scientists have identified new anti-aging compounds produced by a little-studied blood bacterium. These indole metabolites were able to reduce inflammation, oxidative stress, and collagen-damaging activity in skin cell cultures. Three of the ...

Researchers analyzed data from over six million people to see how close residents lived to cannabis retailers. Neighborhoods near these shops experienced higher cannabis-related emergency visits compared with those farther away. The effect was ...

Researchers found that repeated head impacts can disrupt a key system that helps the brain wash away waste. In professional fighters, this system initially seems to work harder after trauma, then declines over time. MRI scans revealed that these ...
