U.S. counties located closer to operational nuclear power plants (NPPs) have higher rates of cancer mortality than those located farther away, according to a new study led by Harvard T.H. Chan School of Public Health. The study is the first of the 21st century to analyze proximity to NPPs and cancer mortality across all NPPs and every U.S. county. The researchers emphasized that the findings are not enough to establish causality but do highlight the need for further research into nuclear power’s health impacts.

Researchers from several partner institutions of the German Center for Diabetes Research (DZD) have collaborated with international colleagues to develop a new approach for visualizing subtle tissue changes in the pancreas in type 2 diabetes. The results provide new insights into the development of type 2 diabetes. The study has now been published in Nature Communications.
