For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

Numerical simulations provide a mechanism that explains how celestial objects such as stars and galaxies can generate ordered, macroscopic magnetic fields. The mechanism arises from turbulence — ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

A newly developed model defines the upper limit to the strength of planetary magnetic fields. The model can help better ...
