New research reveals that cells of the same chronological age can follow dramatically different biological aging paths, offering new insights into cancer, neurodegeneration, and the fundamental biology of aging. Rather than aging uniformly, tissues become a mosaic of biologically younger and older cells, with some individual cells aging much faster than others—a discovery that could reshape how scientists understand aging and the earliest origins of age-related disease.

An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical first days after birth.

Researchers discovered an unexpected role for TRF2 in preserving muscle stem cell identity, offering new insights into muscle regeneration and muscular dystrophy.

Researchers at the University of Tartu have discovered a mechanism in bacteria that helps them adapt to fluoride, which is toxic to most organisms above relatively low threshold concentrations. Their discovery may represent a significant milestone in bioindustry, as it could help reduce the use of petrochemical products.
