New computer code for mechanics of tissues and cells in three dimensions

Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of ...

Fluid dynamics researchers shed light on how partially submerged objects experience drag

One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing it to a steady flow to measure its resistance in the form of ...

Manipulating chromosomes in living cells reveals that they are fluid

For the first time, scientists from CNRS, Institut Curie and Sorbonne Université have been able to act physically on chromosomes in living cells. By subjecting the chromosomes to different forces using magnets, they discovered ...

Two-dimensional chiral fluid mostly follows hydrodynamics theories

A team of researchers with members from several institutions in the U.S. and one in France has created a two-dimensional chiral fluid that mostly follows hydrodynamics theories. In their paper published in the journal Nature ...

Computer model suggests earthquakes are triggered well beyond fluid injection zones

Using data from field experiments and modeling of ground faults, researchers at Tufts University have discovered that the practice of subsurface fluid injection used in 'fracking' and wastewater disposal for oil and gas exploration ...

Putting some skin in the turbulence game

An algorithm that improves simulations of turbulent flows by enabling the accurate calculation of a parameter called skin friction has been developed by KAUST researchers in collaboration with researchers at the California ...

Hundred-year-old law on fluid flow overturned by new research

Engineers from Imperial College London have dispelled a 100-year-old scientific law used to describe how fluid flows through rocks.

Sneezing produces complex fluid cascade, not a simple spray

Here's some incentive to cover your mouth the next time you sneeze: New high-speed videos captured by MIT researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long filaments ...
