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 ...

Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at ...

A new study published in theProceedings of the National Academy of Sciences provides evidence that a specific style of meditation may alter the circulation of fluids within the brain. The findings ...

Every fluid -- from Earth's atmosphere to blood pumping through the human body -- has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter ...

When we talk about climate change, we tend to focus on its more tangible effects: extreme heat, ocean warming, melting glaciers, and so on. But anywhere from 500 meters to a few kilometers beneath our ...

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, ...

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 ...
