Scientists from Germany, Japan, and India have demonstrated that femtosecond laser pulses can force an entire layer of molecules to rotate in unison on a two-dimensional quantum material, a result ...

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

Researchers have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, called ...

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 ...
