Scientists took blood cells from an 80-year-old and reset their molecular age to under 20 in the lab.

Story Snapshot University of Bonn team reprogrammed old human blood-cell precursors into youthful neural stem cells. Age “reset” was measured by molecular clocks that track DNA and epigenetic marks. The work used human cells, not mice, and produced cells that can form ne...

Scientists have found the exact molecular door that lets a common gut bacteria toxin break into colon cells and set off damage linked to cancer, solving a mystery that has puzzled researchers for 15 years.
