From Big Think, Feb. 6, 2023: For the first time, the proton’s size and structure was measured using Fermilab’s MINERVA detector by studying proton/neutrino interactions. This new method, which studies weak force interactions, is a first step in which scientists can use to better understand the laws of the Universe.

Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced in a seminar at Fermilab on December 8, 2006 the first evidence of single top quarks produced in a rare subatomic process involving the weak nuclear force.
