From Interesting Engineering, Oct. 4, 2020: Fermilab’s NOvA experiment is listed in this rundown of the world’s neutrino observatories.

A scientist, avid runner and Cajun food cook, Bryan Ramson is helping solve the universe’s mysteries as a member of two Fermilab-hosted neutrino experiments: NOvA and the international Deep Underground Neutrino Experiment. Eager to share the joy of science with others, Ramson is active in physics outreach in the Chicago community.

From Argonne National Laboratory, Sept. 28, 2020: A research team from four national laboratories, including Fermilab and Argonne, have undertaken work at two Fermilab neutrino experiments — MiniBooNE and NOvA — to construct a model of how neutrinos interact with atomic nuclei. This knowledge is essential to unravel an even bigger mystery: why during their journey through space or matter neutrinos magically morph from one into another of three possible types or flavors.

Handedness — and the related concept of chirality — are double-sided ways of understanding how matter breaks symmetries. Different-handed object pairs reveal some puzzling asymmetries in the way our universe works.

From Scientific American, Sept. 22, 2020: The Chinese JUNO experiment will aim to answer a mystery about the particles’ mass. It will be joined by the international Deep Underground Neutrino Experiment later this decade in its search for answers that neutrinos can provide. Fermilab Deputy Director Joe Lykken weighs in on how neutrinos will address the universe’s pressing questions.

Scientists are testing the components and systems for the international Deep Underground Neutrino Experiment, hosted by Fermilab, with other liquid-argon particle detectors. One such detector is ICEBERG, which is over 10,000 times smaller than DUNE will be. ICEBERG’s measurements are providing insight for future neutrino experiments.

From Spektrum, Sept. 16, 2020: Mit neuen Experimenten wollen Forscher herausfinden, ob es eine vierte Variante des Neutrinos gibt. Sollte sie existieren, könnte das Einblicke in den rätselhaften dunklen Sektor des Universums erlauben.

Particle physics is driven by surprise. Researchers in the 1960s studying tiny but ubiquitous particles called neutrinos found only a fraction of what they expected to be in their detector. That unexpected result eventually led to the discovery that neutrinos are shape-shifters, oscillating between three types as they travel. In this stop-motion video, Symmetry writer Zack Savitsky imagines a painter discovering a similar surprise among his art supplies.

From CERN Courier, Sept. 9, 2020: The first ICHEP meeting since the publication of the update of the European strategy for particle physics covered Higgs and neutrino physics, including results from the CMS collider experiment and the DUNE, NOvA and MicroBooNE neutrino experiments.

From Pour la Science, Aug. 24, 2020: Les neutrinos existent en trois variétés, mais certains indices suggèrent l’existence d’une quatrième, qui pourrait jouer un rôle important en cosmologie. Des expériences sont en cours afin de détecter ces hypothétiques particules. Les données de MiniBooNE n’ont fait qu’appuyer davantage les arguments en faveur de cette quatrième saveur de neutrino.
