An international team of researchers has found it likely that bipedal dinosaurs swung their tails as they walked and ran to maintain their balance. In their paper published in the journal Science Advances, the group describes ...
Physicists have, for the first time, now built a theoretical construct of beams made of twisted atoms. These findings by Armen Hayrapetyan and colleagues at Ruprecht-Karls-University Heidelberg in Germany are about to be ...

(Phys.org)—A team of researchers with members from institutions in Germany and Israel has developed a way to launch plasmons with controlled amounts of angular momentum using spiral-like structures fashioned into a smooth ...
A University of Tokyo research group has successfully measured the spin Hall effect in a superconductor for the first time. The spin Hall effect is responsible for the conversion of magnetic flow to current flow and has not ...
