Scientists discover hidden wolf DNA in most dogs

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, including tiny…

Millions are about to choose the wrong Medicare plan

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—not just premiums—can prevent…

Hidden blood molecules show surprising anti-aging power

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…

Where cannabis stores cluster, emergency visits climb

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…

Repeated head impacts may quietly break the brain’s cleanup system

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…

Your daily orange juice could be helping your heart

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.

A tiny enzyme may hold the key to safer pain relief

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 capture stunning real-time images of DNA damage and repair

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…

Boosting one protein helps the brain protect itself from Alzheimer’s

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…
