From Bioengineer.org, March 21, 2023: Congratulations to Mary Bishai, distinguished scientist from Brookhaven National Laboratory, who has been elected co-spokesperson of the international project DUNE. Bishai began working on DUNE in 2012 and will lead DUNE’s 1,400-member international collaboration alongside Sergio Bertolucci, a physics professor at the University of Bologna.

From Scientific American, March 16, 2023: Big news about a smaller size: MINERvA researchers used a new and entirely independent method to measure a proton’s radius. The team’s measurement of the proton’s radius was 0.73 femtometer, even smaller than the 0.84-femtometer electric charge radius. In either case, it is almost 10,000 times smaller than a hydrogen atom.
From BBC Sky at Night Magazine, March 13, 2023: BBC speaks with Dr. Elena Gramellini, a Lederman Fellow at Fermilab, whose field of research is experimental particle physics and neutrino detectors. Dr. Gramellini explains neutrinos, cosmic building blocks and what they can tell us about the early Universe.
From Physics World, March 6, 2023: The MINERvA experiment at Fermilab has been used to study the structure of the proton using neutrinos. Teijin Cai and colleagues working on Fermilab’s MINERvA experiment have showed how information about the proton can be extracted from neutrinos that have been scattered by the detector’s plastic target.
The quest to understand the small mass of neutrinos is also a quest to discover new particles.
Most astronomers trek to the mountaintops to study the stars, but a group of physicists are seeking the secrets of the cosmos with a detector at the bottom of the ocean.
From Science Daily, Feb. 1, 2023: Yesterday, Nature posted new research which used a beam of neutrinos for the first time to investigate the structure of protons. With Fermilab’s MINERvA detector, scientists were able to precisely measure the proton’s size and structure using neutrinos with data gathered from thousands of neutrino-hydrogen scattering events.
For the first time, particle physicists have been able to precisely measure the proton’s size and structure using neutrinos with data gathered from thousands of neutrino-hydrogen scattering events collected by MINERvA, a particle physics experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory.
For decades, scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed.
From Laser Focus World, Jan. 12, 2023: What does the future of detectors look like and what problems will they solve? Advances in novel detectors are working on some of the most elusive mysteries in science—from quantum teleportation to neutrinos and dark matter. The long-baseline neutrino detectors of DUNE are part of this line up of international detectors.
