Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once.

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.

From Rapid City Journal-Our Northern Hills, November 4, 2021: Excavation crews at the underground site of DUNE reached an important milestone. They completed the careful excavation of the ventilation shaft with just one drill bit during the entire four-and-a-half-month process. Crews also uncovered a 1-1/2 foot thick chunk of quartz crystal during the process that miraculously was not damaged by the reamer head, nor by the 300-foot fall it sustained, marking it a gem of the milestone.

From CNN, November 4, 2021: Fermilab’s Don Lincoln examines the astronomical measurements recorded from a laboratory at the South Pole to explain one of the theories of, “How did the universe come into existence?”

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 Innovation News Network, November 1, 2021: The MPOD/MMS universal low/high voltage multichannel power supply system is helping to drive research and science at some of the world’s most highly respected laboratories, including CERN and Fermilab.

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 the US Department of Energy, October 29, 2021: The US DOE announced $6 million for collaborative research in high energy physics that involves substantial collaboration with Japanese investigators. Research supported under this initiative is expected to include experimental work at DOE’s Fermi National Accelerator Laboratory and at the Japan Proton Accelerator Research Complex (J-PARC) in Japan, as well as the study of rare particles produced at the SuperKEKB collider at the High Energy Accelerator Research Organization (KEK) in Japan.

From DOE, October 29, 2021: Dark Matter Day was October 31, and the Department of Energy’s national labs are dedicated to studying the dark energy and dark matter that makes up the unknown part of our Universe.
