3D-printed particles propel themselves across the surface of a fluid
A small team of physicists at the University of Amsterdam has demonstrated the ability of 3D-printed particles to propel themselves across the surface of a fluid, given the right fuel. The group has posted a paper describing ...
Tiny rotating particles create vorticity in viscous fluids, yielding fascinating new behaviors
Vorticity, a measure of the local rotation or swirling motion in a fluid, has long been studied by physicists and mathematicians. The dynamics of vorticity is governed by the famed Navier-Stokes equations, which tell us that ...
How tiny droplets can deform ice: Findings show potential for cryopreservation and food engineering
When water freezes slowly, the location where water turns into ice—known as the freezing front—forms a straight line. Researchers from the University of Twente showed how droplets that interact with such a freezing front ...

Fluids thicken at the speed of light: A new theory extends Einstein's relativity to real fluids
The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length contraction and time dilation. If an object travels at a relative speed, which is a non-negligible ...
Experiment reveals how Earth's magnetic field influences flow in planet's core
A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth's magnetic field may be influencing internal ...
The secrets of baseball's magic mud: Study quantifies its properties to show it's not simply a superstition
The unique properties of baseball's famed "magic" mud have never been scientifically quantified—until now. In a paper in Proceedings of the National Academy of Sciences, researchers at the University of Pennsylvania School ...

New image recognition technique for counting particles provides diffusion information
A team of scientists have invented a technique to determine the dynamics of microscopic interacting particles by using image recognition to count the number of particles in an imaginary box. By changing the size of the observation ...
Study finds optimal standing positions in airport smoking lounges
While many smoking rooms in U.S. airports have closed in recent years, they are still common in other airports around the world. These lounges can be ventilated, but how much does it actually help the dispersion of smoke?

Scientists demonstrate precise control over artificial microswimmers using electric fields
In a new study in Physical Review Letters, scientists have demonstrated a method to control artificial microswimmers using electric fields and fluid flow. These microscopic droplets could pave the way for targeted drug delivery ...
Investigating the flow of fluids with non-monotonic, 'S-shaped' rheology
Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. ...
