What if a material that looks solid could actually flow… over nearly a century? Launched in 1927 by an Australian professor to illustrate viscosity, an experiment of disarming simplicity has become a ...

Viscosity and rheology are critical in formulation, especially as syringeability and manufacturability of high-concentration, subcutaneous biologics are in focus. Classic viscometers require large ...

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, ...

The observations were so unbelievable that the researchers needed to repeat the experiments to "make sure it was real.” ...
