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

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 ...

Image of digital twin control, in which real plasma is controlled by virtual plasma reproduced on a computer. In this research, we developed a digital twin control system that can estimate optimal ...

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 ...

Electric (plasma) propulsion devices have been used for applications such as station-keeping and orbit transfer, in place of chemical rockets, because they provide a higher specific impulse. Detailed ...

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 ...

The sun's convection zone plays a key role in the generation and evolution of the Sun's magnetic field. Analyzing data sets spanning more than 20 years, researchers have obtained the most ...

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) ...

Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only ...
