'Featherweight oxygen' discovery opens window on nuclear symmetry

Researchers at Washington University in St. Louis have discovered and characterized a new form of oxygen dubbed "featherweight oxygen"—the lightest-ever version of the familiar chemical element oxygen, with only three neutrons ...

Getting a big look at tiny particles

At the turn of the 20th century, scientists discovered that atoms were composed of smaller particles. They found that inside each atom, negatively charged electrons orbit a nucleus made of positively charged protons and neutral ...

Physicists discover new class of pentaquarks

Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding ...

Spin flipper upends protons

Protons spin. It's an intrinsic property that can affect experiments at accelerators that use beams of protons. Yet flipping proton spins could offer insights into nuclear physics experiments that study the first moments ...

Making a fast ion transporter

An international team of researchers at Institute for Molecular Science in Japan and Max Planck Institute of Biophysics in Germany has revealed an ion transport mechanism of sodium/proton antiporter by simulating its motion. ...

Optimizing proton beam therapy with mathematical models

Particle beam therapy is increasingly being used to treat many types of cancer. It consists in subjecting tumours to beams of high-energy charged particles such as protons. Although more targeted than conventional radiotherapy ...
