Reducing Arsenic in Drinking Water Cuts Risk of Death, Even After Years of Chronic Exposure
Published today in JAMA, a 20-year study of nearly 11,000 adults in Bangladesh found that lowering arsenic levels in drinking water reduced the risk of death from chronic illnesses, compared with continued exposure.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
