How does the brain clean itself during sleep? A new ultrafast MRI method tracks cerebrospinal fluid flow without contrast agents, revealing how vasomotor waves drive the brain's "nightly wash." ...

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 ...

New work could help design electronic devices in which heat can be guided in certain directions, minimizing heat loss ...

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 ...

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 ...

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 ...

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 ...
