Unraveling turbulence: New insights into how fluids transform from order to disorder
Turbulence is everywhere—it rattles our planes and makes tiny whirlpools in our bathtubs—but it is one of the least understood phenomena in classical physics.

Magnetic vortices are nanoscale whirls that gyrate like spinning tops, tracing out paths in a clockwise or counter-clockwise manner in nanometer-thick materials. Under certain conditions, this sense of gyration can flip repeatedly, ...

Acoustic tweezers are based on focused acoustic vortices and hold promise to precisely manipulate microorganisms and cells from the millimeter scale down to the submicron scale, without contact, and with unprecedented selectivity ...
Scientists at the U.S. Department of Energy's Ames Laboratory have developed a method to accurately measure the "exact edge" or onset at which a magnetic field enters a superconducting material. The knowledge of this threshold— ...
