Story summary

A groundbreaking study reveals that as we age, gut bacteria release a metabolite called ADP-heptose into the bloodstream, fueling the growth of pre-leukemic cells associated with a condition known as clonal hematopoiesis of indeterminate potential (CHIP). This affects 10-20% of adults over 70, heightening the risk of blood cancers and heart disease. Unraveling this link could pave the way for innovative preventive measures.
