Women taking estrogen had fewer signs of Alzheimer’s in their brains
Women using estrogen-only hormone therapy in later life showed 39% lower odds of dementia diagnosis and 35% lower odds of Alzheimer's-related brain changes. A study of over 21,000 participants found hormone therapy users had reduced amyloid plaques and tau tangles at autopsy.

Blue and fin whales are being sighted with increasing frequency in the southeastern Atlantic more than 40 years after commercial whaling ended. Ninety-five percent of confirmed observations from a 60-year dataset were recorded since 2012, indicating recent population recovery in Namibian and South African waters.
Wheat gene behind Hessian fly resistance cloned after 50-year search
A wheat gene conferring resistance to Hessian fly larvae has been cloned after a 50-year search, with researchers demonstrating its direct interaction with an insect protein. The gene's identification was published in Science Advances on August 14, 2026, opening pathways for engineering pest resistance in wheat crops.
Engineered microbe speeds CO₂ capture and recovers critical metals
A genetically engineered bacterium rapidly breaks down feldspar, one of Earth's most abundant minerals, to simultaneously remove atmospheric carbon dioxide and recover critical elements for electric vehicle batteries. The engineered microbe accomplishes this through a single biological process rather than requiring separate industrial steps.
