A research group has demonstrated that spontaneously excited plasma waves may be the solution to a long-associated problem with magnetic nozzle plasma thrusters, turning conventional thinking on its head.
Details of their research were published in the journal Scientific Reports on December 5, 2022.

The English poet William Blake famously implored readers to "see the world in a grain of sand." In Physics of Fluids, by AIP Publishing, scientists from the University of Campinas, in Brazil, and the University of California, Los Angeles, have been doing just that - studying the "granular" dynamics of how crescent-shaped sand dunes are formed.

In the Mojave Desert, the sun beats down on the ground and makes pockets of low pressure. Cool air rushes into these areas, where it warms and rises, creating vortices that pick up dust. These types of dust devils aren't limited to Earth: They are found on Mars at sizes reaching 1,600 meters in diameter.
