UrduResearchers have experimentally extracted the strength of the strong force, a quantity that firmly supports theories explaining how most of the mass or ordinary matter in the universe is generated. This quantity, known as the coupling of the strong force, describes how strongly two bodies interact or “couple” under this force. With Jefferson Lab data, the physicists were able to determine the strong force coupling at the largest distances yet.

Mouse Cell Studies Show That Correcting DNA Disorganization Could Aid Diagnosis and Treatment of Rare Inherited Diseases
Hopkins Medicine researchers say they have found that a protein that helps form a structural network under the surface of the cell’s “command center” — its nucleus — is key to ensuring that DNA inside it remains orderly.

Nuclear Physicists on the Hunt for Squeezed Protons
While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe. Now, researchers hunting for these squeezed protons have come up empty-handed, suggesting there’s more to the phenomenon than first thought. The result was recently published in Physical Review Letters.
Looking skin deep at the growth of neutron stars
Researchers leveraged data from nuclear scattering experiments to make stringent constraints on how neutrons and protons arrange themselves in the nucleus. Their predictions are tightly connected to how large neutron stars grow and what elements are likely synthesized in neutron star mergers.
Analyzing Matter’s Building Blocks
Nobuo Sato is working to put the know in femto. He’s just been awarded a five-year, multimillion dollar research grant by the Department of Energy to develop a “FemtoAnalyzer” that will help nuclear physicists image the three-dimensional internal structure of protons and neutrons. Now, Sato is among 76 scientists nationwide who have been awarded a grant through the DOE Office of Science’s Early Career Research Program to pursue their research.
