How to feed a black hole

A special magnetic effect, the so-called magnetorotational instability (MRI), plays a key role in the formation of stars and planetary systems. It is also what feeds the black holes in the center of galaxies. For the first time, this effect has been observed in a laboratory experiment at the Forschungszentrum Dresden-Rossendorf (Germany). These results have recently been published in Physical Review Letters.
