Robotic swimmer sheds light on microorganisms in motion

Just by moving around, microorganisms like bacteria and sperm are performing a remarkable feat. The effects of viscosity are amplified at small scales, which means a microorganism swimming in water is a bit like a person ...

Magnetic surprise revealed in 'magic-angle' graphene

When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called "magic-angle graphene" ...
