From World Nuclear News, December 7, 2021: A neutrino detection kit has been installed in the containment of Argentina’s Atucha 2 reactor in support of a US-Argentine experiment to learn more about the mysterious particles. Scientists of the vIOLETTA Project are using sensitive Skipper CCD equipment designed and prepared by Fermilab and Berkeley labs. It will be able to detect interactions between neutrinos and a silicon matrix. The experimental arrangement will give them insights on neutrinos at previously unexplored low energy ranges.

As part of the international Deep Underground Neutrino Experiment, a UK-US collaboration is preparing for industrial scale production of large particle detector components. This fall, it’s taking the first ones for a final test-drive.
From Physics World, December 1, 2021: Researchers say there are gaps in the theory of neutrino-nucleus interactions and that improving this theory is crucial if next-generation neutrino detectors such as the Deep Underground Neutrino Experiment (DUNE) in the U.S. and Hyper-Kamiokande in Japan are to realize their full potential.
From Universe Today, November 5, 2021: Neutrinos might make up a small portion of dark matter, but most dark matter must be something else. Because neutrinos are so close to satisfying the properties of dark matter, some scientists have argued dark matter might be a yet undiscovered variety known as sterile neutrinos.What did Fermilab’s newest experiment MicroBooNE see?
From Le Scienze (France), November 4, 2021: The preliminary analysis of three years of data from the MicroBooNE experiment show no signs of the existence of a fourth type of neutrino. The standard model of particle physics remains confirmed but it has not excluded clues to exotic physical phenomena may emerge.
From Scientific American, November 4, 2021: Physicists have wondered if neutrino particles come in a mysterious fourth variety. Now new experimental findings complicate the question.

Physicists have wondered if neutrino particles come in a mysterious fourth variety. The MicroBooNE experiment findings announced last week by Fermilab heightened the mystery of why too many particles showed up in a detector during an experiment on the 1990s.
From Quanta, October 28, 2021: In 1993, Los Alamos National Laboratory saw hints of a fourth kind of neutrino which led to MiniBooNE. Now the results of MicroBooNE reveal sterile neutrinos alone cannot account for the MiniBooNE anomaly and the results are consistent with the possibility that only half of MiniBooNE’s events are due to neutrino oscillations.
From Newsweek, October 28, 2021: Physicists were left with more questions than answers after a longsearch for an elusive theoretical particle called a sterile neutrino. The results were released last week by scientists working with the MicroBooNE neutrino experiment based at Fermilab.
From Forbes, October 27, 2021: Fermilab’s Don Lincoln discusses the journey of the hypothetical sterile neutrino and the results of the MicroBooNE experiment hosted at Fermilab. Have sterile neutrinos been ruled out?
