Why the search for dark matter depends on ancient shipwrecks

    From The Atlantic, Oct. 25, 2019: Errant particles from everyday radioactive materials are a major obstacle for particle physicists. The solution? Lead from the bottom of the sea. Fermilab archivist Valerie Higgins is quoted in this piece on materials from old ships reused for physics experiments.

    DOE funds new physics research in dark matter

      From Washington University’s The Source, Oct. 23, 2019: The Department of Energy has awarded new funding to boost research on dark matter, the mysterious substance that makes up an astounding 85% of the matter in the universe. The Axion Dark Matter eXperiment is one of the fund’s recipients, and a number of Washington University scientists are collaborating on the project.

      The future of particle physics is bright, bleak, and magical

        From Gizmodo, Oct. 23, 2019: Ahead lies a whole frontier in particle physics of grand unsolved mysteries, including why there’s more matter than antimatter in the universe, what the true identity of dark matter and dark energy is, or how the strange, ultraweak neutrino particles ended up so ghostly. The Fermilab-hosted DUNE and Muon g-2 experiments are among those looking for answers.

        How frozen atoms could help us learn more from gravitational waves

          From MIT Technology Review, Oct. 21, 2019: We’ve seen ripples in space-time only when the universe’s biggest events occur. Now there might be a way to spot them ahead of time. MAGIS-100 is a project designed to see whether shooting frozen atoms with lasers can be used to observe ultrasensitive signals that might be stretching through space-time. If successful, it could help usher in a new era of “atom interferometry” that could reveal some of the secrets of gravitational waves, dark matter, quantum mechanics, and other heady topics.
