Plasma jets stabilize water to splash less

A study by KAIST researchers revealed that an ionized gas jet blowing onto water, also known as a 'plasma jet," produces a more stable interaction with the water's surface compared to a neutral gas jet. This finding reported ...

Understanding the utility of plasmas for medical applications

Plasma medicine is an emerging field, as plasmas show promise for use in a wide range of therapies from wound healing to cancer treatment. Plasma jets are the main plasma sources typically used in plasma-surface applications. ...

Spinning black hole powers jet by magnetic flux

Black holes are at the center of almost all galaxies that have been studied so far. They have an unimaginably large mass and therefore attract matter, gas and even light. But they can also emit matter in the form of plasma ...

Fossil fuel-free jet propulsion with air plasmas

Humans depend on fossil fuels as their primary energy source, especially in transportation. However, fossil fuels are both unsustainable and unsafe, serving as the largest source of greenhouse gas emissions and leading to ...

Astrophysicists wear 3-D glasses to watch quasars

A team of researchers from Russia and Greece reports a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3-D image by feeding each ...

Astronomers find quasars are not nailed to the sky

Until recently, quasars were thought to have essentially fixed positions in the sky. While near-Earth objects move along complex trajectories, quasars are so remote that they were believed to offer stable and reliable reference ...
