The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature. The ...

Summary: A multidisciplinary neuroengineering study has broken a major imaging barrier by mapping the exact flow velocity of the brain’s waste-clearing infrastructure. The research utilizes ...

From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the ...

Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...
