For Protons and Neutrons, Things Aren’t the Same Inside Nuclei
Department of Energy, Office of Science

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.

Monitoring “frothy” magma gases could help evade disaster
University of Tokyo

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.

Theorists Propose a Novel Way to Measure Gluons’ Orbital Motion
Department of Energy, Office of Science

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.

Predicting Explosive Energy Bursts in Compact Fusion Power Plants
Department of Energy, Office of Science

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.

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.
