Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

For most fluids, an increase in pressure should lead to a burst of speed, like squeezing ketchup from a tube. But when flowing through porous materials such as soil or sedimentary rock, certain ...

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, ...

It's a common misconception that fluids with different flow rate requirements always need separate pumps. In reality, that's not necessarily the case. Image Credit: Fluid Metering, Inc. When working ...

A study finds chiral structures, with mirror-image configurations, can emerge from nonchiral systems, suggesting new ways to engineer these materials. Hold your hands out in front of you, and no ...
