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 compounds, including two never seen before, showed particularly…
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 strongest where multiple stores were packed…
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 changes…
Most of us think of orange juice as a simple breakfast habit, something you pour without much thought. Yet scientists are discovering that this everyday drink may be doing far more in the body than quenching thirst.
When we talk about “patient engagement” in research, it can sound like a slogan on a grant application rather than something that changes people’s lives.
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 nearby proteins in a…
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 flare up, track…
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 treatment also reduced plaque levels…
Dr. Smita Das often hears the same myth: You can’t get hooked on pot. And the misconception has become more widespread as a growing number of states legalize marijuana. Around half now allow recreational use for adults and 40 states…
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 key…
