As black holes feed, they pull material into a disk around them. The material orbiting in this disk gets heated to extreme temperatures, and so it becomes a plasma — a state of matter in which some of ...

Plasma, often regarded as the fourth state of matter, exhibits complex dynamics when interacting with magnetic fields. These interactions underpin numerous natural and technological processes, from ...

Helicon plasma propulsion represents a promising and multifaceted approach in the domain of electric space propulsion. At its core, the technology utilises helicon waves to generate high-density ...

Precisely tuning the spacing between iron oxide nanoparticles optimizes their magnetic interactions to enhance MRI contrast, offering a simpler path to better imaging agents. (Nanowerk News) Magnetic ...

A research team at the University of Tokyo has built a fluorescence microscopy system that can detect fleeting magnetic ...

Mechanisms of macrophage regulation mediated by iron-based mag netic nanomaterials. SOD, superoxide dismutase; POD, peroxidase; CAT, cata lase; NF-κB, nuclear factor-kappa B; MAPK, mitogen-activated ...

Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Earth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth’s sliver of life-sustaining atmosphere by deflecting high energy ...
