Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...

With a powerful enough light, you can see things that people once thought would be impossible. Large-scale light source facilities generate that powerful light, and scientists use it to create more ...

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...

Vinod M. Menon and his research group at The City College of New York shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses ...

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These giants — some are billions of times heavier than our sun — can shoot out ...

Discover how to build a magnetic repulsion motor capable of lighting LED bulbs using only magnets and basic components. This step-by-step tutorial covers the construction of the magnetic base, the ...

In 1929, Ernest Orlando Lawrence invented the cyclotron: a compact, efficient particle accelerator that used magnets. Two years later, he founded what ...
