Studying the tetraneutron, once thought unlikely to exist, may improve our understanding of interneutron forces, from unstable two- and three-neutron systems to...

This image shows the basic setup that enables researchers to use lasers as optical "tweezers" to pick individual atoms out from a cloud and hold them in place. The atoms are imaged onto a camera, and the traps are...
This image shows the results of scanning X-ray microdiffraction (μSXRD) with submicron spatial resolution. Lauediffraction (a) from an unconstrained Sb2S3 single crystal (top) and laser fabricated RLS crystal Sb2S3 (bottom).Magnified images (b) of selected reflection (852) extracted from Laue...

It's a common swimming pool game: Force a buoyant ball underwater and let it go. The ball springs to the surface and jumps into the air. But, submerge the ball...

Researchers at the Department of Energy's Oak Ridge National Laboratory have demonstrated that permanent magnets produced by...
Researchers at the University of Houston have reported a new method for inducing superconductivity in non-superconducting materials, demonstrating a concept proposed decades ago but never proven.
The technique can also be used to boost the efficiency of known superconducting materials,...
