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 ...

A new technique combined with changes in material design is making reversible viscosity modulations possible, according to researchers from the University of Guelph in Ontario, Canada. By connecting ...

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 ...

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, ...

Every fleet owner should know the basics about the viscosity of the lubricants they are using and why the viscosity matters. Fleets—especially mixed ones—require a variety of lubricants. This ranges ...

In the 1960s, drillers noticed that certain fluids would firm up if they flowed too fast. Researchers have finally explained why. Fluids can be roughly divided into two categories: regular ones and ...
