The movements within Earth’s molten core have been resisting efforts to understand them for a long time, but agreement between a mathematical and physical model has led two physicists to claim they ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

In thin, two-dimensional semiconductors, electrons move, spin and synchronize in unusual ways. For researchers, understanding the way these electrons carry out their intricate dances— and learning to ...

Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum ...

UC Santa Cruz applied mathematicians produced the first self-consistent models of the Sun’s tachocline incorporating the ...

Researchers in South Korea have created magnetic nanohelices that can control electron spin at room temperature. Spintronics, also called spin electronics, explores information processing by using the ...

To their surprise, when the model was allowed to run under these conditions, a tachocline emerged on its own. Even more revealing, the simulations showed that the magnetic fields produced in the ...

We may finally know the secret to how migrating birds can sense Earth’s magnetic fields: a molecule in their eyes called cryptochrome 4 that is sensitive to magnetism, potentially giving the animals ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...
