How does the brain clean itself during sleep? A new ultrafast MRI method tracks cerebrospinal fluid flow without contrast ...

A new, AI-based technique for measuring fluid flow in the brain could lead to treatments for diseases such as Alzheimer's. A new artificial intelligence-based technique for measuring fluid flow around ...

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 ...

Water makes up around 60% of the human body. More than half of this water is inside the cells that make up organs and tissues, and much of the remaining water flows in the spaces between cells. MIT ...

Scientific progress is not usually straightforward. Researchers pursue and abandon lines of inquiry. Results languish. Theories take decades to cohere. But sometimes the accumulation of scientific ...

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes.

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, ...

A new artificial intelligence-based technique for measuring fluid flow around the brain’s blood vessels could have big implications for developing treatments for diseases such as Alzheimer’s. The ...
