New view on electron interactions in graphene

Electrons in graphene—an atomically thin, flexible and incredibly strong substance that has captured the imagination of materials scientists and physicists alike—move at the speed of light, and behave like they have no ...

Microbots individually controlled using 'mini force fields'

Researchers are using a technology likened to "mini force fields" to independently control individual microrobots operating within groups, an advance aimed at using the tiny machines in areas including manufacturing and medicine.

Surprisingly strong magnetic fields challenge black holes' pull

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched ...
