The new Dark Energy Survey year five results used machine learning to obtain a new measurement that offers insights into the density of the mysterious force driving the Universe’s expansion. The results were presented recently at the 243rd meeting of the American Astronomical Society meeting. What does this all mean? Don Lincoln explains.

In the culmination of a decade’s worth of effort, the DES collaboration of scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.

Don Lincoln explores the mysteries of black holes and if we will ever really know what lies in the center of these enormous cosmic regions in space.

Interesting Engineering lists the top seven amazing innovations that pushed the boundaries of science and technology in 2023. Included in this line up is the latest announcement from the Muon g-2 collaboration with more evidence of a new force of nature that could revolutionize our understanding of the universe.

To determine whether sterile neutrinos exist, researchers at Fermilab have constructed two new detectors as part of the Short-Baseline Neutrino (SBN) Program that they hope will resolve the situation once and for all.

The major part of the excavation of the caverns for the Long Baseline Neutrino Facility at SURF is nearing completion. The caverns will house the very large detectors for the Deep Underground Neutrino Experiment in Lead, South Dakota.

Fermilab research and announcements have helped promote the mystery of muons by studying how they wobble as they move through the magnetic ring. With science announcements in 2021 and 2023, science interested readers are wanting to learn more about the heavy cousins of electrons that are constantly raining down on Earth’s surface.

The most recent P5 report suggests funding support for research at Argonne and Fermilab, showing Chicagoland as a hub for the future of particle physics. The report recommended exploring the possibility of building a revolutionary new particle collider at Fermilab, more powerful than the LHC, and reinforced support of the Fermilab led DUNE project.

Fermilab’s MINERvA experiment was chosen as one of the nine runners up as part of the Physics World 2023 Breakthrough of the Year. The MINERvA research shows how information about the internal structure of the proton can be gleaned from neutrinos scattering from a plastic target.

The recent report published by the Particle Physics Project Prioritization Panel highlights the important role that Sanford Underground Research Facility plays in the advancement of U.S. particles physics and its support of the DUNE project. The P5 report recommends continued support for DUNE and funding for expansion of research space at SURF that will enable the U.S. to be an international host for neutrino and dark matter experiments.
