(PhysOrg.com) -- "Brownian motion is a very old concept," Klaus Kroy tells PhysOrg.com. "The laws explaining it were formulated more than a century ago by Albert Einstein. However, we are finding some interesting divergences ...
Stirring can allow the dispersion of substances evenly in liquid. Einstein's tea leaf paradox is a concept that shows how tea leaves can concentrate in a doughnut shape through a secondary flow effect during stirring. In ...
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating ...
Physicists from the University of Utrecht and the Faculty of Physics at the University of Warsaw have observed—for the first time experimentally—the Brazil nut effect in a mixture of charged colloidal particles.

A team of researchers at Macquarie University, in Australia, working with two colleagues from Universität Hamburg, in Germany, has uncovered the means by which the Australian ant-slayer spider is able to capture and eat ...
Researchers in Japan have discovered that the local DNA motion inside of human cells remains steady throughout interphase, where the cell grows and replicates its DNA for cell division. The study suggests that this steady-state ...

Using the Rozhen National Astronomical Observatory (NAO) in Bulgaria, astronomers have performed long-term monitoring of the quasar QSO B1312+7837 and have detected a periodic variability of this source. The finding is reported ...
University of Colorado Boulder researchers have discovered that minuscule, self-propelled particles called "nanoswimmers" can escape from mazes as much as 20 times faster than other passive particles, paving the way for their ...
