Science Magazine (July 24) -- A National Academies of Sciences, Engineering, and Medicine committee glowingly approved of the science that could be done with a proposed Electron-Ion Collider, a billion-dollar accelerator that would probe the innards of protons and neutrons. The EIC would help maintain U.S. expertise in colliding beams, says Gordon Baym, a theorist at the U. of I. and co-chair of the report committee. “It’s the only collider in the U.S. that’s being considered for the next 50 years or so.”
