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 ...

A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate. Encased in the skull, perched atop the spine, the brain has a ...

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 ...

The famed Navier-Stokes equations can lead to cases where more than one result is possible, but only in an extremely narrow set of situations. For nearly two centuries, all kinds of researchers ...

For more than 250 years, mathematicians have been trying to “blow up” some of the most important equations in physics: those that describe how fluids flow. If they succeed, then they will have ...

In the most basic of terms, rheology can be considered the study of flow behavior in materials, whether solid, liquid, or gas. Rheology recognizes that certain solids respond with plastic flow in ...

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 ...
