A newly designed optical centrifuge allows scientists to control molecular rotation inside superfluid helium nano-droplets.

Using centuries old equations of fluid motion, supercomputers can be used to simulate turbulent flow in fine detail. But theoretical physicists are still unsure as to how these equations actually work ...

Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ...

American researchers have measured a tiny electrical voltage by exploiting Earth's magnetic field in the planet's rotational motion. This discovery, though modest, revives a scientific debate nearly ...
