New discoveries about the nature of light could improve methods for heating fusion plasma
Princeton Plasma Physics Laboratory

Scientists have made discoveries about light particles known as photons that could aid the quest for fusion energy.

Newswise: Precision Measurements of Radioactive Molecules for Fundamental Physics
Released: 22-May-2024 4:05 PM EDT
Precision Measurements of Radioactive Molecules for Fundamental Physics
Department of Energy, Office of Science

For the first time, nuclear physicists made precision measurements of the short-lived radioactive molecule, radium monofluoride (RaF). The researchers combined ion-trapping and specialized laser systems to measure the fine details of the quantum structure of RaF. This allowed them to study the rotational energy levels of RaF and determine its laser-cooling scheme.

Promethium bound: Rare earth element’s secrets exposed
Oak Ridge National Laboratory

Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.

Newswise: Recycling carbon dioxide into household chemicals

Recycling carbon dioxide into household chemicals
Argonne National Laboratory

Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.

Newswise: Tracking Down Toxic Metals From Tobacco Smoke

Tracking Down Toxic Metals From Tobacco Smoke
Lawrence Berkeley National Laboratory

Homes and public places where people smoke may have high levels of harmful trace metals from cigarettes, even after smoking stops, Berkeley Lab researchers have found. These metals include cadmium, arsenic, and chromium, and the levels may be above safety limits set by California.

Newswise: Seeing the Color of Entangled Photons in Molecular Systems
Released: 20-May-2024 2:05 PM EDT
Seeing the Color of Entangled Photons in Molecular Systems
Department of Energy, Office of Science

Spectroscopy allows scientists to study the structure of atoms and molecules, including the energy levels of their electrons. This research examines the potential of spectroscopy techniques that rely on quantum entanglement of these photons. These methods can reveal information about molecules not possible with traditional spectroscopy. They also reduce the damage spectroscopy causes to samples.

A waterfall lost and a river found
Oak Ridge National Laboratory

Matt and Brandon traveled to Ecuador's rainforests to map the Coca River with drones. The river is experiencing massive erosion and sedimentation problems after the San Rafael waterfall collapsed in 2020. Their work could help the country save a hydroelectric power plant that provides 30% of the country's electricity as well as roads and pipelines the area's people depend on for commerce and transportation.

Newswise: STAR Sees a Magnetic Imprint on Deconfined Nuclear Matter

STAR Sees a Magnetic Imprint on Deconfined Nuclear Matter
Department of Energy, Office of Science

Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in “deconfined” nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
