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.

From Building Design and Construction, October 26, 2021: Fermilab’s Industrial Center Building Addition has received Novel 20 recognition as a new construction envelope project that achieved 20 percent above a code baseline. Better Buildings Building Envelope Campaign honorees were recognized by the U.S. Department of Energy. The award honors building teams for their leadership in envelope performance.

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?

From Yale News, October 27, 2021: On Oct. 27, the international MicroBooNE collaboration announced the first results of MicroBooNE’s search for an anomaly that could have indicated a fourth type of neutrino, a subatomic particle considered a fundamental building block of matter.

From the BBC, October 27, 2021: Yesterday, the MIcroBooNE collaboration opened a new chapter in physics with the announcement of their results; the search failed to find the particle, known as the sterile neutrino.

Four complementary analyses by Fermilab’s MicroBooNE show no signs of a theorized fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments.

A new analysis of the South Pole-based telescope’s observations has all but ruled out several popular models of inflation.

From Sanford Underground Research Facility, October 25, 2021: SURF will be hosting a gameshow-themed event. as part of the virtual event, “Deep Talks: Are you smarter than a dark matter physicist?” on Thursday, Oct. 28, from 6 to 7 p.m. MT. All are invited to attend the event where the audience will take part in a quiz about dark matter and the LUX-ZEPLIN (LZ) dark matter experiment.

From Tech Start Ups, October 24, 2021: How antimatter can one day power a rocket into space. Former Fermilab physicist Gerald Jackson believes testing an antimatter-based propulsion spacecraft could be a reality by 2050 if the high energy costs to produce antimatter weren’t a factor.

In early October, crews completed the raise-bore drilling of the vertical ventilation shaft at the Lead, South Dakota, LBNF/DUNE project site and unexpectedly uncovered a geological treasure during the process.
