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 . ...

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 ...

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 ...

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 climb sharply. While . ...

Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone's activity was blocked. The findings help explain how ...

A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection--reducing heart attack, stroke, and death in adults with type 2 diabetes. While companies have claimed large ...

Researchers discovered that the common amino acid arginine can block harmful A aggregation and reduce its toxic effects in Alzheimer's disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved behavior ...

Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept their nerves healthier. A drug already being ...

A new airflow device from UBC Okanagan engineers traps exhaled aerosols almost immediately, sharply reducing pathogen exposure in indoor spaces. Early simulations suggest it could outperform existing ventilation systems by a wide margin.

Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut disease.
