Jan. 23, 2026 Chemotherapy’s gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels ...

This One Gene May Explain Most Alzheimer’s Cases

Jan. 23, 2026 Alzheimer’s may be driven far more by genetics than previously thought, with one gene playing an outsized role. Researchers found that up to nine in ten cases could be linked to the APOE gene — ...

The Bottled Water Everyone Trusts May Be the Riskiest
