MIT study finds children more vulnerable to cancer-causing chemical in water (opens in new tab)

A troubling new study from MIT reveals that a common environmental contaminant, NDMA—found in polluted water, certain medications, and even processed foods—may pose a far greater cancer risk to children than adults. In experiments with mice, young animals exposed to the chemical developed significantly more DNA damage and cancer, despite experiencing the same initial exposure as adults. The key difference lies in how rapidly children’s cells divide, which turns early DNA damage into dangerous...
