How Big Is a Proton? Neutrinos Weigh In
A first-of-its-kind probe brings physicists one step closer to solving the proton radius puzzleOne of two magnetic focusing horns used in the beamline at Fermilab that produces intense neutrino beams for MINERvA and other neutrino experiments.

Gamma rays and neutrinos from mellow supermassive black holes
The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain unexplained. Now, an international research team has proposed a scenario that explains these; black holes with low activity act as major factories of high-energy cosmic particles. Details of their research were…
