New feedback system can improve efficiency of fusion reactions

Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The ...

Strange radio burst raises new questions

Astronomers have found only the second example of a highly active, repeating fast radio burst (FRB) with a compact source of weaker but persistent radio emission between bursts. The discovery raises new questions about the ...

Hyperpolic shear polaritons in low-symmetry crystals

Scientists from the Fritz Haber Institute of the Max Planck Society, Vanderbilt University, City University of New York, University of Nebraska, and University of Iowa have just published new results on asymmetric light-matter ...
