Sitting still or going hunting: Which works better?

For the kinds of animals that are most familiar to us—ones that are big enough to see—it's a no-brainer: Is it better to sit around and wait for food to come to you, or to move around and find it? Larger animals that ...

A new way to identify stresses in complex fluids

Fluid dynamics researchers use many techniques to study turbulent flows like ocean currents, or the swirling atmosphere of other planets. Arezoo Adrekani's team has discovered that a mathematical construct used in these fields ...

Simulating the shear destruction of red blood cells

Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular ...

How flow shapes bacterial biofilms

EPFL biophysicists have taken a systematic look into how bacterial biofilms are affected by fluid flow. The findings can give us clues about the physical rules guiding biofilm architecture, but also about the social dynamics ...

Researchers crack an enduring physics enigma

For decades, physicists, engineers and mathematicians have failed to explain a remarkable phenomenon in fluid mechanics: the natural tendency of turbulence in fluids to move from disordered chaos to perfectly parallel patterns ...
