Co-author institution on fusion reactor axion paper

Fusion reactors might crack open the dark matter mystery without trying. University of Cincinnati physicist Jure Zupan and colleagues at Fermilab, MIT, and Technion just published a breakthrough showing how neutrons slamming into reactor walls could spawn axions—the hypothetical particles that may explain the 27% of the universe we can't see. The twist: we're already building these reactors for clean energy.
