Astrophysicists work toward unification of turbulence framework—weak-to-strong transition discovered in turbulence

Turbulence is ubiquitous in nature. It exists everywhere, from our daily lives to the distant universe, while being labeled as "the last great unsolved problem of classical physics" by Richard Feynman. Prof. Dr. Huirong Yan ...

Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved

In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, ...

Liquid droplets shape how cells respond to change, shows study

Healthy cells respond appropriately to changes in their environment. They do this by sensing what's happening outside and relaying a command to the precise biomolecule in the precise domain that can carry out the necessary ...

Two-dimensional nanomaterial sets expansion record

It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist ...

NASA observations find what helps heat roots of 'moss' on sun

Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified ...

Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares

Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected ...

BepiColombo detects escaping oxygen and carbon in unexplored region of Venus's magnetosphere

A fleeting visit of the ESA/JAXA BepiColombo mission to Venus has revealed surprising insights into how gases are stripped away from the upper layers of the planet's atmosphere.

Exoplanets true to size: New model calculations shows impact of star's brightness and magnetic activity

In the constellation Virgo, 700 light years away from Earth, the planet WASP-39b orbits the star WASP-39. The gas giant, which takes little more than four days to complete one orbit, is one of the best-studied exoplanets. ...
