Can Electricity Flow Without Electrons?

Department of Energy, Office of Science — Fri, 21 Mar 2025 18:20:40 EST

Scientists have long held that electricity is carried by individual electrons with discrete charges moving in a metal, even in the case of electrons clumped into quasiparticles. However, "strange metals" fail to obey this paradigm. Researchers have observed a radical quantum blurring of electrons in strange metal into a featureless liquid, potentially pointing toward a new theory of electrical transport.

UA Little Rock Reopens Historic Observatory Following Solar Eclipse Event

University of Arkansas at Little Rock — Thu, 20 Mar 2025 10:10:40 EST

The University of Arkansas at Little Rock is reopening its observatory after more than a decade of inactivity, thanks in part to the overwhelming enthusiasm sparked by the university's public event for the Great North American Eclipse on April 8, 2024. The observatory, located atop Stabler Hall, has undergone renovations and will officially celebrate its reopening March 31.

Testing the Possible Doubly Magic Nature of Tin-100, Researchers Study the Electromagnetic Properties of Indium Isotopes

Department of Energy, Office of Science — Wed, 19 Mar 2025 20:25:12 EST

Atomic nuclei with "magic numbers" of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists are especially interested in nuclei with doubly magic numbers--those that have full shells for both protons and neutrons. One example is the tin isotope Sn-100, which has 50 protons and 50 neutrons. To prepare for future work on Sn-100, researchers studied the properties of isotopes of indium as they approached 50 neutrons. This helps to demonstrate how adding single particles changes the properties of a nucleus.

Latest Dark Energy Survey Data Suggest Possible Variations in Dark Energy Over Time

NSF's NOIRLab — Wed, 19 Mar 2025 18:05:00 EST

A groundbreaking new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as ΛCDM. If confirmed, these findings could fundamentally alter our understanding of the Universe. DES was conducted using the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Victor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab.

DESI Opens Access to the Largest 3D Map of the Universe Yet

Tantalizing Hints That Dark Energy is Evolving -- New Results and Data Released by the DESI Project

NSF's NOIRLab — Wed, 19 Mar 2025 18:00:00 EST

The DESI collaboration has published a new analysis of dark energy using their first three years of collected data, which spans nearly 15 million galaxies and quasars. Combined with studies of the cosmic microwave background, supernovae, and weak lensing, the analysis hints that dark energy changes over time. Data Release 1, containing data from DESI's survey validation and first year of observations, has now been made available for scientists and the public to explore.

New DESI Results Strengthen Hints That Dark Energy May Evolve

Lawrence Berkeley National Laboratory — Wed, 19 Mar 2025 18:00:00 EST

The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining the DESI data with other experiments shows signs that the impact of dark energy may be weakening over time -- and the standard model of how the universe works may need an update.

LLNL and Verne Demonstrate Highly Efficient Hydrogen Densification Pathway with Less Required Energy

What's Behind the 'Pop and Slosh' When Opening a Swing-Top Bottle of Beer?

American Institute of Physics (AIP) — Tue, 18 Mar 2025 11:00:00 EST

In Physics of Fluids, researchers from the University of Gottingen in Germany decided to use a high-speed camera to capture what occurs while opening a swing-top bottle of beer. They found that the sound emitted by opening a pressurized bottle with a swing-top lid isn't a single shockwave, but rather a very quick "ah" sound.
