Newswise: Fighting Cancer on Earth and in Space Using High-Energy Protons
Released: 14-Oct-2022 9:55 AM EDT
Fighting Cancer on Earth and in Space Using High-Energy Protons
Department of Energy, Office of Science

Scientists use high-energy protons to create isotopes for cancer treatment. In space, such protons pose a risk to astronauts and spacecraft. To learn more about both the risks from these protons and about methods of using these protons to produce medical isotopes, scientists measured the cross sections (probabilities) for high-energy proton reactions used to produce radiopharmaceuticals. The research helps to optimize the quantity and purity of medical isotopes and improve the design of spacecraft shielding.

Machine Learning Takes Hold in Nuclear Physics
Thomas Jefferson National Accelerator Facility

Scientists have begun turning to new tools offered by machine learning to help save time and money. In the past several years, nuclear physics has seen a flurry of machine learning projects come online, with many papers published on the subject. Now, 18 authors from 11 institutions summarize this explosion of artificial intelligence-aided work in “Machine Learning in Nuclear Physics,” a paper recently published in Reviews of Modern Physics.

New measurements quantifying qudits provide glimpse of quantum future
Oak Ridge National Laboratory

Using existing experimental and computational resources, a multi-institutional team has developed an effective method for measuring high-dimensional qudits encoded in quantum frequency combs, which are a type of photon source, on a single optical chip.

Stability in asymmetry: Scientists extend qubit lifetimes
Argonne National Laboratory

Adaptable and versatile, molecular qubits hold promise for numerous quantum applications. By altering the qubit's host environment, a team supported by the Q-NEXT quantum center has extended the length of time these qubits can maintain information.

Newswise: Discovered Tetraneutron Resonance Confirms Theoretical Predictions

Discovered Tetraneutron Resonance Confirms Theoretical Predictions
Department of Energy, Office of Science

In a new experiment, scientists have finally found the long-sought tetraneutron predicted using theory and supercomputer support at least six years ago. The tetraneutron is a combination of four neutrally charged neutrons. Unlike individual neutrons and combinations of two or three neutrons, the tetraneutron has a stable state—called a resonant state—that is long enough to be determined by the new experiment. The results are an important advance for nuclear physics and understanding of the strong nuclear force.

New tool helps researchers investigate clouds, rain and climate change
Argonne National Laboratory

Climate scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, Pennsylvania State University and the NASA Goddard Institute for Space Studies created an open-source research platform to generate highly accurate climate models.

Engineering Duckweed to Produce Oil for Biofuels, Bioproducts
Brookhaven National Laboratory

Scientists at Brookhaven National Laboratory and collaborators at Cold Spring Harbor Laboratory have engineered duckweed to produce high yields of oil. The team added genes to one of nature's fastest growing aquatic plants to "push" the synthesis of fatty acids, "pull" those fatty acids into oils, and "protect" the oil from degradation.

Through thick and thin: X-rays track the behavior of soft materials
Argonne National Laboratory

In a pair of recently published papers, two independent research teams successfully used a powerful X-ray beam technique at the APS to uncover new insights about the dynamics of materials such as toothpaste and hair gel.

Newswise: Watching Plants Switch on Genes
Released: 7-Oct-2022 2:40 PM EDT
Watching Plants Switch on Genes
Department of Energy, Office of Science

Researchers attach green fluorescent protein (GFP), a protein that changes light from one color into another, to other proteins to observe how and where cells produce those proteins and thus how cells express genes. However, the use of GFP is time consuming and requires expensive equipment. Researchers have now designed and developed a special type of GFP visible with the unaided eye and a simple black light.
