Hybrid device harvests both mechanical and magnetic energy

A new hybrid energy-harvesting device may one day replace the need for batteries in certain low-power electronics devices. The new device collects ambient wasted energy from both mechanical vibrations and magnetic fields to generate sustainable electricity, which could potentially provide enough power to run wireless sensors, cardio pacemakers, and other applications.

Understanding the universe through neutrinos

Determining features of the elusive particle known as a neutrino – through the observation of an extremely rare nuclear process called neutrinoless double-beta decay (NDBD)—could provide a glimpse into the nature of the universe during the earliest moments of the Big Bang.

Tuning into quantum: Scientists unlock signal frequency control of precision atom qubits

Scientists have achieved a new milestone in their approach to creating a quantum computer chip in silicon, demonstrating the ability to tune the control frequency of a qubit by engineering its atomic configuration.

Theorists publish highest-precision prediction of muon magnetic anomaly

Theoretical physicists at the U.S. Department of Energy's (DOE's) Brookhaven National Laboratory and their collaborators have just released the most precise prediction of how subatomic particles called muons—heavy cousins of electrons—"wobble" off their path in a powerful magnetic field. The calculations take into account how muons interact with all other known particles through three of nature's four fundamental forces (the strong nuclear force, the weak nuclear force, and electromagnetism) while reducing the greatest source of uncertainty in the prediction.

Students from Missouri, Mississippi to Call Space Station

Students in St. Louis and southern Mississippi will get to ask questions of NASA astronauts on the International Space Station during two events next week as part of NASA’s Year of Education on Station.

Theorists publish highest-precision prediction of muon magnetic anomaly

Latest calculation based on how subatomic muons interact with all known particles comes out just in time for comparison with precision measurements at new 'Muon g-2' experiment.

Researchers interpret new experimental data aimed at showing dark matter interacts with ordinary matter

An international team of scientists that includes University of California, Riverside, physicist Hai-Bo Yu has imposed conditions on how dark matter may interact with ordinary matter—constraints that can help identify the elusive dark matter particle and detect it on Earth.

How might dark matter interact with ordinary matter?

Scientists have imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM.

Researcher discusses IceCube neutrino sensor array

Dozens of scientists and engineers across multiple divisions at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) played a role in the design, development, and deployment of the IceCube neutrino sensor array at the South Pole. They pioneered the ice-embedded digital optical modules (DOMs) and circuitry that are IceCube's key enabling technologies. Berkeley Lab researchers also contributed to a predecessor experiment called AMANDA (the Antarctic Muon and Neutrino Detector Array).
