Mapping Out Neutrino Hotspots Here on Earth
Scientists have been chasing neutrino particles that were spewed out after the formation of the universe. But neutrinos also form on our own planet, by the natural decay of radioactive elements and as byproducts from nuclear power plants. Reporting in Scientific Reports, a team of scientists mapped out both “geoneutrinos” and manmade neutrinos. Physicist Stephen Dye, an author on that study, explains how neutrinos can be used to probe the deepest parts of the earth, as well as to keep an eye on global nuclear projects.

Stephen Dye is physics professor at Hawaii Pacific University and the University of Hawaii. He’s based in Honolulu, Hawaii.
