Theoretical models of dark matter predict that its signals can be detected using low-background radiation detectors. By looking for specific types of dark matter and finding no signal, scientists operating the Majorana Demonstrator experiment have significantly narrowed the characteristics of potential dark matter particles. The results will help design future experiments.
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter. The evidence comes from measuring the way differently charged particles separate when emerging from collisions of atomic nuclei at this DOE Office of Science user facility.
Experiments at the Swiss Light Source SLS prove the existence of a new type of magnetism, with broad implications for technology and research.

Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) that may display possible aurorae, like the familiar Northern Lights on our world. This is an unexpected mystery because the brown dwarf, known as W1935, is an isolated object in space, with no nearby star to create an aurora.
As the particle physics community releases its strategic plan for the next 10 years and overall vision for the next 20, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have started planning how the Lab is positioned to contribute to a range of the plan’s science goals, new experiments, proposed research facilities, and ongoing projects.
Scientists have confirmed possible evidence of a new elementary particle, the sterile neutrino. The results from the Baksan Experiment on Sterile Transitions (BEST) found that the germanium 71 yield was 20% to 24% lower than expected based on the intensity of the neutrino source and on scientists’ knowledge of how neutrinos are absorbed. This is consistent with earlier results on the so-called gallium anomaly.
Spintronic devices are electronic devices that utilize the spin of electrons (an intrinsic form of angular momentum possessed by the electron) to achieve high-speed processing and low-cost data storage. In this regard, spin-transfer torque is a key phenomenon that enables ultrafast and low-power spintronic devices.
Tetraneutron is an elusive atomic nucleus consisting of four neutrons, whose existence has been highly debated by scientists. This stems primarily from our lack of knowledge about systems consisting of only neutrons, since most atomic nuclei are usually made of a combination of protons and neutrons.

New calculations predicting the spatial distributions of the charges, momentum, and other properties of the quarks within protons found that the up quarks are more symmetrically distributed and spread over a smaller distance within the proton than the down quark. The results imply that these two types of quarks contribute differently to a proton’s properties.

In APL Materials, researchers tested a molecular energy harvesting device that captures the energy from the natural motion of molecules in a liquid. Their work showed molecular motion can be used to generate a stable electric current. To create the device, they submerged nanoarrays of piezoelectric material in liquid, allowing the movement of the liquid to move the strands like seaweed waving in the ocean, except in this case the movement is on the molecular scale, and the strands are made of zinc oxide. When the zinc oxide material waves, bends, or deforms under motion, it generates electric potential.
