From CERN, March 24, 2021: A memorandum of understanding (MoU) between CERN and Fermilab, signed on 23 March, details Fermilab’s contributions to the High-Luminosity LHC project.

From Huxiu.com, March 15, 2021: Fermilab’s SeaQuest experiment is hailed for discovering a “sea” of quarks surging inside the proton.
An experiment that will contribute vital knowledge about something deceptively simple – a proton’s spin – will soon come online at Fermilab. The experiment may either begin to validate the “potato salad” model of proton spin or force scientists to develop a new model entirely.
From NewScientist, March 8, 2021: The recent experiment results of asymmetry in protons published in Nature calling out the new research used to improve measurement techniques from Fermilab’s SeaQuest detector.
From Science & Vie, March 4, 2021: Fermilab was included with other accelerator labs for their discoveries of new particles and materials in this French science magazine.
From the Science of the Francis Mule, March 1, 2021: Scientists at Fermilab and Argonne publish new results from SeaQuest experiment showing the asymmetry of protons.
From Reccom Magazine, Feb. 26, 2021: Chuck Brown of the Fermilab SeaQuest research team is quoted in this piece on the sea of quarks inside the proton. The article discusses Fermilab’s contributions to the SeaQuest and NuSea experiments.
From Los Alamos Laboratory News, Feb. 24, 2021: The E-906/SeaQuest experiment, hosted by Fermilab, has produced results that are the opposite of what had previously been understood about proton structure and the dynamics of strong interacting antiquarks and gluons.
Protons are built from three quarks — two “up” quarks and one “down” quark. But they also contain a roiling sea of transient quarks and antiquarks that fluctuate into existence before swiftly annihilating one another. At the Fermilab-hosted SeaQuest experiment, researchers report that that lopsidedness persists in a realm of previously unexplored quark momenta.
Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it.
