Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.

New clues on the source of the universe's magnetic fields      (via sciencedaily.com) 

Researchers offer insight into the source of cosmic magnetic fields. The research team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Their simulations showed that, in addition to generating new magnetic fields, the turbulence of those plasmas can also amplify magnetic fields once they've been generated, which helps explain how magnetic fields that originate on small scales can sometimes eventually reach to stretch across vast distances.

New algorithm ensnares its first 'potentially hazardous' asteroid      (via sciencedaily.com) 

An asteroid discovery algorithm -- designed to uncover near-Earth asteroids for the Vera C. Rubin Observatory's upcoming 10-year survey of the night sky -- has identified its first 'potentially hazardous' asteroid, a term for space rocks in Earth's vicinity that scientists like to keep an eye on. The roughly 600-foot-long asteroid, designated 2022 SF289, was discovered during a test drive of the algorithm with the ATLAS survey in Hawaii. Finding 2022 SF289, which poses no risk to Earth for the foreseeable future, confirms that the next-generation algorithm, known as HelioLinc3D, can identify near-Earth asteroids with fewer and more dispersed observations than required by today's methods.

When electrons slowly vanish during cooling      (via sciencedaily.com) 

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

James Webb Space Telescope sees Jupiter moons in a new light      (via sciencedaily.com) 

Last year, JWST made spectral observations of Ganymede and infrared observations of Io. Absorption lines of hydrogen peroxide at Ganymede's poles indicate radiolysis of water ice by charged particles funneled by the moon's magnetic field. Io had two major eruptions, one associated with a forbidden emission line of sulfur monoxide. The latter supports a theory that SO is produced at volcanic vents in a thin atmosphere that allows forbidden emission before collisions destroy the excited state.

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

Listen to a star 'twinkle'      (via sciencedaily.com)     Original source 

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.
