Liquids can follow twisted paths when flowing through porous media. Read More »
By injecting momentum into the fluid around an object, researchers can freely switch between obscuring the object’s presence and canceling hydrodynamic forces on it. Read More »
Fluid flows induced by nutrient gradients in the vicinity of microbial colonies help direct the expansion of those microbes into new territory. Read More »
Currents induced by an evaporating drop increase the efficiency of the Leidenfrost effect for liquid substrates. Read More »
Theorists have developed a model to explain how a protein structure keeps its position while being buffeted by currents. Read More »
A surprising effect traps dye particles within narrow bands in a tank of whirling fluid. Such focusing may influence chemical reactions and the motions of water vapor in the atmosphere. Read More »
A zigzag arrangement that appears spontaneously in a collection of magnetic particles and some other colloids is explained by the fluid flow around each particle. Read More »
Physicists develop a theory to make the seemingly random, thermally driven motion of particles in fluids predictable. Read More »
Computer modeling shows that surprisingly large regions can trap particles carried by a fluid that is moving steadily through a pipe junction. Read More »
The direction in which fluid circulates in binary drops doesn't change when the drops are tilted, implicating gravity—not surface tension—as the driver of flow in these systems. Read More »
