From PBS Space Time, Jan. 6, 2020: Why is there something rather than nothing? The answer may be found in the weakest particle in the universe: the neutrino. In this 10-minute video, PBS Space Time host Matt O’Dowd and Fermilab scientist Don Lincoln explore the mysteries of the neutrino and how Fermilab is tackling them. The elusive neutrino may hold powerful secrets, from the unification of the forces of nature to the biggest question of all: Why is there something rather than nothing?

Underneath the vast, frozen landscape of the South Pole lies IceCube, a gigantic observatory dedicated to finding ghostly subatomic particles called neutrinos. Neutrinos stream through Earth from all directions, but they are lightweight, abundant and hardly interact with their surroundings. A forthcoming upgrade to the IceCube detector will provide deeper insights into the elusive particles.

From Black Hills Pioneer, Dec. 13, 2019: Scientists at Fermilab and the Sanford Underground Research Facility in South Dakota are eager to begin collecting data from the Long-Baseline Neutrino Facility and the international Deep Underground Neutrino Experiment, which is hosted by Fermilab. But before the world’s largest neutrino experiment can begin producing results, more than 800,000 tons of rock will need to be removed from the 4,850-foot level of a former mine to make room for the detectors.

Scientists on Fermilab’s MicroBooNE experiment have measured neutrino interactions on argon with unprecedented statistics and precision using data on the resultant muons — in particular, the muon’s momentum and angle. The experiment features the first liquid-argon time projection chamber with the resolution and statistics to carry out such a measurement. Researchers will use the result to improve simulations of neutrino interactions. These improvements are important for neutrino experiments in general, including the Short-Baseline Neutrino program experiments and the international Deep Underground Neutrino Experiment, both hosted by Fermilab.

From UC Riverside, Dec. 4, 2019: The University of California, Riverside is participating in the international Deep Underground Neutrino Experiment, which brings together more than 1,000 scientists from around the world to learn more about ghostly particles called neutrinos.

From The Mac Observer, Nov. 25, 2019: In this 30-minute podcast episode, Fermilab scientist Dan Hooper recounts how he caught the astrophysics bug as an undergraduate, landed a postdoc position at Oxford and was later hired at Fermilab. He chats about his interest in the interface between particle physics and cosmology, dark matter and what neutrinos can tell us about the early universe.
