From Department of Energy, June 28, 2021: DOE announces $93 million in funding for 71 research projects that will spur new discoveries in high-energy physics. The projects—housed at 50 colleges and universities across 29 states—are exploring the basics of energy science that underlie technological advancements in medicine, computing, energy technologies, manufacturing, national security and more.

From Kathimerini (Greece), June 14, 2021: A multinational team of 400 researchers from 25 research centers in seven countries announced the results of the DES study that looked at 226 million galaxies and thousands of supernova explosions. The DES measurements, like those of other similar galactic surveys, informed us that the current universe is less dense than our model predicts.
From Yahoo, May 30, 2021: Scientists from the Dark Energy Survey collaboration have just released the best dark matter map yet, but it’s not answering every question — if anything, the cosmos may be more mysterious than ever.
From Cosmos, May 29, 2021: The Dark Energy Survey collaboration released the most precise look at the universe’s evolution to understand dark matter and dark energy by studying how they shape the large-scale structure of the universe.
From Universe Today, May 30, 2021: The Dark Energy Survey camera (DECam) was funded by the Department of Energy (DOE) and was built and tested at Fermilab. The DES took place over 6 years from 2013 to 2019, and looked at over 1/8th of the night sky for a total of 758 night
The Dark Energy Survey collaboration has created the largest ever maps of the distribution and shapes of galaxies, tracing both ordinary and dark matter in the universe out to a distance of over 7 billion light years. The analysis, which includes the first three years of data from the survey, is consistent with predictions from the current best model of the universe, the standard cosmological model. Nevertheless, there remain hints from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.
From EIN Presswire, May 14, 2021; LBNL’s LArPix experiment result is a leap forward in how to detect and record signals in liquid argon time projection chambers (LArTPCs), a technology of choice for future neutrino and dark matter experiments such as Fermilab’s DUNE.
From Forbes, May 14, 2021: Fermilab senior scientist Don Lincoln discusses measuring the size of neutron stars and the result of a measurement showing that the centers of neutron stars are stiff and not squishy.
From Sanford Lab, May 10, 2021: Activities at the Sanford Underground Research Facility will have significant benefits for the state of South Dakota over the next decade.
From Forbes, April 29, 2021: Don Lincoln discusses a possible model of dark matter called a WIMP, short for weakly interacting massive particle.
