Storm in a cosmic teacup: A new paradigm for understanding plasma turbulence
On the path to writing his Ph.D. dissertation, Lucio Milanese made a discovery—one that refocused his research, and will now likely dominate his thesis.

Laser-wakefield accelerators have led to the development of compact, ultrashort X-ray or gamma-ray sources to deliver peak brilliance, similar to conventional synchrotron sources. However, such sources are withheld by low ...
Nearly 50 years ago, Brown University physicist Michael Kosterlitz and his colleagues used the mathematics of topology—the study of how objects can be deformed by stretching or twisting but not tearing or breaking—to ...

When a fire extinguisher is opened, the compressed carbon dioxide forms ice crystals around the nozzle, providing a visual example of the physics principle that gases and plasmas cool as they expand. When our sun expels plasma ...

Billions of years ago, in the center of a galaxy cluster far, far away (15 billion light-years, to be exact), a black hole spewed out jets of plasma. As the plasma rushed out of the black hole, it pushed away material, creating ...

Kinetic instabilities commonly arise from anisotropic (different properties in different directions) electron velocity distributions within ionospheric, cosmic and terrestrial plasmas. But only a handful of experiments have ...
How do researchers explore nature on its most fundamental level? They build "supermicroscopes" that can resolve atomic and subatomic details. This won't work with visible light, but they can probe the tiniest dimensions of ...
