Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard numbers.

A built-in "compass" made of magnetic nanoparticles helps them to reliably find the optimal habitat. Researchers at the University of Basel have now unlocked the magnetic properties of individual ...
