A good dark matter detector has a lot in common with a good teleconference setup: You need a sensitive microphone and a quiet room. The SENSEI experiment has demonstrated world-leading sensitivity and the low background needed for an effective search for low-mass dark matter.

From The Great Courses Daily, June 2, 2020: Fermilab scientist Don Lincoln writes about modern science: how it is a process for fitting facts into some interconnected whole, for a bigger picture, why it’s an extremely powerful tool and the different terms for the meaning of basic scientific methods.

From Physics Today, June 1, 2020: Somewhere in the laws of physics, particles must be allowed to behave differently from their antiparticles. If they weren’t, the universe would contain equal amounts of matter and antimatter, all the particles and antiparticles would promptly annihilate one another, and none of us would exist. Fermilab’s NOvA neutrino experiment and the international Deep Underground Neutrino Experiment, hosted by Fermilab, are pinning down CP violation, the property that could explain the imbalance.

From Physics Today, June 1, 2020: Fermilab’s Chris Quigg and University of Chicago’s Mel Shochet recount the extraordinary career of Fermilab physicist and National Medal of Technology recipient Alvin Tollestrup, who died on Feb. 9.

The Dark Energy Spectroscopic Instrument, which will map millions of galaxies in 3-D, reaches final milestone toward its startup.
