Active flow control using plasma actuators offers a novel and increasingly influential method for manipulating aerodynamic flows. By utilising the dielectric barrier discharge mechanism, these devices ...

This news release is available in Japanese. Katsumi Ida and colleagues at the National Institute for Fusion Science (NIFS) of the National Institutes of Natural Sciences (NINS) and Shigeru Inagaki of ...

A Chinese-American collaboration has figured out how to run fusion reactors harder -- and more efficient at the same time. Share on Facebook (opens in a new window) Share on X (opens in a new window) ...

For 400 years people have tracked sunspots, the dark patches that appear for weeks at a time on the sun's surface. They have observed but been unable to explain why the number of spots peaks every 11 ...

Plasma arc cutting (PAC) is a thermal cutting technique widely used in manufacturing applications such as shipbuilding, ...

A promising technique for tracking boost-glide hypersonic vehicles involves detecting radio waves emitted by plasma in the wake. Passive detection would be a valuable capability, since existing ...

Beneath the Sun's outer shell, a layer of highly ionized, boiling hot gas flows all the way down to 200,000 kilometers below the surface of the star. Temperatures of this plasma can reach up to 45,000 ...

A helioseismology study maps the flow of plasma inside the Sun and supports a model that also explains the sunspot cycle. The results of a new helioseismology study suggest that the Sun’s meridional ...
