For Protons and Neutrons, Things Aren't the Same Inside Nuclei
Quarks are distributed differently in free protons and neutrons versus those inside nuclei, something called "the EMC effect." Scientists previously thought that the EMC effect treated the up and down quarks in protons and neutrons equally. New high-precision data from the MARATHON experiment indicates that the EMC effect may exert more influence on the distribution of down quarks compared to up quarks inside nuclei.

The Interplay Between Epidemics, Prevention Information, and Mass Media
When an epidemic strikes, more than just infections spread. As cases mount, information about the disease, how to spot it, and how to prevent it propagates rapidly among people in affected areas as well.
HK Tech Forum on Quantum Physics and Complex Systems
A central theme of quantum science and technology is the investigation of the properties and the uses of quantum interactions, the characteristic correlations among constituents of a quantum system that have no analogous counterparts in classical systems.
Monitoring "frothy" magma gases could help evade disaster
Volcanic eruptions are dangerous and difficult to predict. A team at the University of Tokyo has found that the ratio of atoms in specific gases released from volcanic fumaroles (gaps in the Earth's surface) can provide an indicator of what is happening to the magma deep below -- similar to taking a blood test to check your health.
Simplified process shines light on new catalyst opportunities
Theory-guided development of an easier, more versatile process for synthesizing unsymmetric ligands provides new avenues of exploration in transitional metal catalysis.
New quantum tool developed in groundbreaking experimental achievement
For the first time in experimental history, researchers at the Institute for Quantum Computing (IQC) have created a device that generates twisted neutrons with well-defined orbital angular momentum.
Theorists Propose a Novel Way to Measure Gluons' Orbital Motion
Subatomic particles' spin dictates how they propagate, interact, and form bound states. But how proton spin arises from quarks and gluons is a mystery, and experimental measurements of the individual contributions of quark and gluon spin don't add up to the proton's total spin. The orbital motion of quarks and gluons in the proton may account for the rest. Theorists have now proposed a way to measure this property using the future Electron-Ion Collider.
Jefferson Lab Welcomes a 'New' Hall Group Leader
After an extensive international search, the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has appointed Mark Jones as the new group leader of the lab's Experimental Halls A and C. He began his tenure Nov. 1.

The award winners, including San Diego Supercomputer Center at UC San Diego, have been recognized in the annual HPCwire Readers' and Editors' Choice Awards, presented at the 2022 International Conference for High Performance Computing, Networking, Storage, and Analysis (SC22), in Dallas, Texas.
Predicting Explosive Energy Bursts in Compact Fusion Power Plants
Edge localized modes (ELMs) associated with plasma instabilities in tokamak fusion reactors can damage reactor walls, a challenge in the design of future fusion power plants. Scientists have now discovered that internal resistance of the plasma can cause additional instabilities that drive ELMs in the National Spherical Torus Experiment. This will help researchers mitigate and control ELMs in spherical tokamaks.
Department of Energy Announces Early Career Research Program for FY 2023
Today, the U.S. Department of Energy (DOE) announced it is accepting applications for the 2023 DOE Office of Science Early Career Research Program to support the research of outstanding scientists early in their careers. The program will support over 80 early career researchers for five years at U.S. academic institutions, DOE national laboratories, and Office of Science user facilities.
Reducing Redundancy to Accelerate Complicated Computations
Computers help physicists solve complicated calculations. But some of these calculations are so complex, a regular computer is not enough. In fact, some advanced calculations tax even the largest supercomputers. Now, scientists at Jefferson Lab and William & Mary have developed MemHC, a new tool that uses memory optimization methods to allow GPU-based computers to calculate the structures of neutrons and protons ten times faster.
