A topical drug that removes aging, damaged cells helped older mice heal skin wounds significantly faster. The treatment appeared to reactivate repair pathways involved in inflammation, collagen production, and new blood vessel growth.

A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug sensitivity in resistant lung cancer cells, and ...

Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep. Individual sensitivity varies dramatically, meaning . ...

A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood vessels associated with inflammation, GAE can ...

Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that . ...

Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar . ...

A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the medications, patients had a 22% higher risk of heart .. ...

A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists a more precise, less invasive way to study the .. ...

Chronic inflammation tied to stress, lifestyle, mental health, and socioeconomic conditions may silently change the heart for years before any symptoms appear. People with the highest inflammation levels faced a 43% greater risk of heart attack and . ...

Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also allowed researchers to grow human hindbrain ...
