Making an object invisible under fluid flow

The invisibility cloak is an artifact that can make the wearer transparent, rendering it undetectable to observers outside. Perhaps, one of the most well-known examples is the invisibility cloak possessed by Harry Potter ...

Aerodynamicists reveal link between fish scales and aircraft drag

The team's findings have been published in Nature: Scientific Reports: "Transition delay using biomimetic fish scale arrays," and in the Journal of Experimental Biology: "Streak formation in flow over biomimetic fish scale ...

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 ...
