High-viscosity fluids, on the other hand, behave quite differently. They flow slowly, resist deformation, and, in some cases, act more like solids than liquids, posing challenges when it comes to ...

The viscosity of extracellular fluid is a key physical cue, but its impact on cell function and cancer-cell dissemination has remained largely unknown. Experiments in various systems reveal that ...

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, ...

New research findings show how higher viscosity, or resistance to flow, of the extracellular fluid that surrounds cells enables cancer cells to migrate more rapidly from a primary tumor to other sites ...

In three spatial dimensions, it is a close relative of the quark-gluon plasma, the super-hot state of matter that hasn’t existed since the tiniest fraction of a second after the big bang that started ...

Ketchup is famous for being hard to get out of the bottle even when there is plenty of it left. In fact, all liquid foods—from red wine to cooking oil—leave some residue in the container. The reason ...
