The electron transport chain (ETC) is crucial for life, as it is essential for cellular ATP production. Most ETC enzymes are large multi-subunit protein assemblies. Of these, complex I is the largest ...

Physicists used MINERvA, a Fermilab neutrino experiment, to measure the proton’s size and structure using a neutrino-scattering technique. For the first time, particle physicists have been able to ...
