Oct. 6, 2026 — Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and ...

Oct. 5, 2026 — Predatory wasps are hijacking shelters built by tropical trees for their ant defenders, potentially disrupting an ancient partnership that protects the plants from hungry insects. The takeover is far more common in disturbed landscapes such as oil ...

Oct. 5, 2026 — Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a ...

Oct. 5, 2026 — Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK ...

Oct. 5, 2026 — NASA has selected the GIMLI project to investigate whether the Marius Hill Pit opens into a vast underground cave or lava tube. Using radar, seismic sensors, gravity measurements, and cameras, researchers will search beneath the lunar surface and ...

Oct. 4, 2026 — Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, ...

Oct. 4, 2026 — A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician ...

Oct. 4, 2026 — A 30-year forestry experiment in Australia found that heavily thinned mountain ash forests grew unusually large trees while recovering enough carbon to match or exceed untouched areas. The results suggest carefully managed thinning could support ...

Oct. 4, 2026 — A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades ...

Oct. 4, 2026 — A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn ...

Oct. 3, 2026 — A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors ...

Oct. 3, 2026 — A two-year randomized clinical trial involving 493 adults with overweight or obesity found that diet soft drinks were essentially as effective as water for long-term weight loss and weight maintenance. Participants drinking beverages sweetened with ...
