Bacteria rule the world—that’s a lesson Kayla Miller, an assistant professor of biology at Dakota Wesleyan University, learned early in her studies. “Every organism in the world has a microbiome,” Miller said. “We don’t see them, we don’t think about them, but they are calling the shots.”

The Majorana Collaboration and the Sanford Underground Research Facility host a discussion of the experiment’s final results as published on Feb. 10, 2023, in Physical Review Letters. The Majorana Collaboration also announced new measurements from a search for the decay of nature’s rarest isotope: tantalum-180m.

Just outside the cavern where the Nobel Prize-winning Solar Neutrino Experiment took place, cosmologist Neta Bahcall tells the story of the science visionaries behind the experiment: her late husband, theorist John Bahcall, and experimentalist Raymond Davis Jr.

Cosmologist Neta Bahcall explores the research of her late husband John Bahcall, whose theory guided the Nobel-Prize-winning Solar Neutrino Experiment at Homestake Gold Mine in Lead, South Dakota, now home to the Sanford Underground Research Facility.
