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…

It’s possible to get addicted to pot. Here’s what to know

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…

New nasal nanodrops wipe out brain tumors in mice

A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach the brain without invasive surgery. When paired with drugs that boost T-cell activity, the…

Stem cell therapy helps AMD patients see again

A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely affected patients. Participants gained measurable sight improvements in the treated eye.…

Just a few cigarettes a day can damage your heart for decades

People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see their risk of heart failure…
