The physics of salad dressing

Researchers at the University of Tokyo have shown that in phase separation in liquids, as is seen when oil and water separate, occurs as a result of the ordered motion of droplets. Initially, a great number of small droplets ...

Scientists prove possibility of 'impossible' dust transition in turbulent flow

Researchers from MIPT and the Weizmann Institute of Science (Israel) have predicted the possibility of negative turbophoresis, a phenomenon where impurity particles inside a turbulent flow move in an "impossible" direction. ...

Inside the cell, an ocean of buffeting waves

Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study led ...
