What tree rings can tell us about the spectacular death of stars

    From CNN, Nov. 28, 2020: The explosion of a supernova is so powerful that modern telescopes can see it half a universe away. A cautious person might wonder, “What would happen to Earth if this happened to a nearby star?” In this article, Fermilab scientist Don Lincoln discusses a paper from University of Colorado at Boulder’s Robert Brakenridge, who claims that he has found evidence here on Earth of nearby supernovae. What form does this evidence take? Ancient radioactive tree rings.

    Un gigantesco laboratorio de neutrinos en Dakota del Sur a kilómetro y medio de profundidad

      From Público, Nov. 24, 2020: Homestake fue la mayor y más profunda mina de oro de de Norteamérica hasta que se cerró en 2002 tras 125 años de funcionamiento. Este remoto lugar de Dakota del Sur se convirtió oficialmente en 2007 en un laboratorio subterráneo de física fundamental, aunque ya mucho antes se habían instalado en sus profundas cavernas algunos experimentos, incluido uno que mereció el premio Nobel. Ahora se anuncia la nueva etapa para convertir la mina en sede del megaproyecto científico más importante de las últimas décadas en Estados Unidos, el Long-Baseline Neutrino Facility, dedicado a estudiar las partículas fundamentales llamadas neutrinos.

      Carlos Henrique de Brito Cruz: an igniter of change

        From Pesquisa, November 2020: The FAPESP scientific director shares how he encouraged behaviors that helped improve research in São Paulo. With FAPESP encouragement, researchers in Brazil have held leadership positions in international collaborations, including in a photon detection system called Arapuca. Arapuca is a technology used in Fermilab’s Short-Baseline Near Detector and a baseline technology for the international Deep Underground Neutrino Experiment, hosted by Fermilab.

        Accelerator makes cross-country trek to enable laser upgrade

          From Jefferson Lab, Nov. 20, 2020: Thomas Jefferson National Accelerator Facility has shipped the final new section of accelerator that it has built for an upgrade of the Linac Coherent Light Source. The section of accelerator, called a cryomodule, has begun a cross-country road trip to SLAC National Accelerator Laboratory, where it will be installed in LCLS-II, the world’s brightest X-ray laser. The upgraded LCLS will boast 37 cryomodules in total. Of those, 18 are from Jefferson Lab (plus three spares), and the rest will come from Fermilab.

          Upgrades to Ross Shaft include new cage, skips and rope replacement

            From Sanford Underground Research Facility, Nov. 24, 2020: Another series of upgrades to the Ross Shaft is underway at the Sanford Underground Research Facility. Crews are working to outfit the shaft with new cage and skip conveyances and have replaced thousands of feet of hoist cables. The work prepares the Ross Shaft for its role as the main travel way for upcoming excavation and construction of the Long-Baseline Neutrino Facility to support the Deep Underground Neutrino Experiment, the world’s flagship neutrino experiment, which is hosted by Fermilab.

            Chicago Quantum Summit highlights new U.S. quantum centers, economic opportunities

              From Chicago Quantum Exchange, Nov. 23, 2020: The third annual Chicago Quantum Summit brought together more than 20 speakers from across the nation and attracted more than 1,000 attendees from 42 countries. This year’s summit comes on the heels of the announcement of five new Department of Energy National Quantum Information Science Research Centers, one of which is the Fermilab-led Superconducting Quantum Materials and Systems Center. At the summit, each center director gave an overview of their quantum center or institute goals, which included building qubit technologies, developing algorithms for quantum computation, and creating new quantum devices.
