A key hurdle facing fusion devices called stellarators — twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars — has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions. Now collaborative research by scientists at the U.S.

Magnetic field lines that wrap around the Earth protect our planet from cosmic rays. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have now found that beams of fast-moving particles launched toward Earth from a satellite could help map the precise shape of the field.

A long-standing puzzle in space science is what triggers fast magnetic reconnection, an explosive process that unfolds throughout the universe more rapidly than theory says it should. Solving the puzzle could enable scientists to better understand and anticipate the process, which ignites solar flares and magnetic space storms that can disrupt cell phone service and black out power grids on Earth.

A Princeton-led mission to study the interaction of the solar wind with the ancient cast-off winds of other stars, and the fundamental process of particle acceleration in space, has completed a critical NASA review and is now moving closer toward a scheduled launch in 2024.

When it comes to car and truck engines, not much has changed since Nikolaus Otto invented the modern internal combustion engine in 1876. But the internal combustion engine could, at least theoretically, be in for a big change.

Creating a star on Earth requires a delicate balance between pumping enormous amounts of energy into plasma to make it hot enough for fusion to occur and preventing that heat from escaping. Now, physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have identified a method by which instabilities can be tamed and heat can be prevented from leaking from the plasma, giving scientists a better grasp on how to optimize conditions for fusion in devices known as tokamaks.

Doughnut-shaped tokamaks — facilities designed to reproduce the fusion energy that powers the sun and stars on Earth — must withstand forces that can be stronger than hurricanes created by disruptions in the plasma that fuels fusion reactions. Recent findings by physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) show that certain forces released by disruptions act in a surprising manner.

Cutting carbon emissions quickly requires a price on carbon, experts from industry, government and academia said at the annual meeting of the Andlinger Center for Energy and the Environment last week. A carbon fee would provide a dual benefit: offer direct incentives to cut emissions, and also create a new market for firms that can monetize carbon dioxide as a resource by transforming the gas into products and fuels.
