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 ...

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, ...

Researchers at the Institute of Industrial Science, The University of Tokyo, used a sophisticated physical model to simulate the behavior of fluids moving through pipes. By including the possibility ...

WEST LAFAYETTE, Ind. — A blood vessel is an elastic tube, and its changing shape affects the properties of the fluid flowing inside it. Conversely, the fluid flow itself also affects the shape of the ...

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 ...

Viscosity is one of the most fundamental physical properties used to describe how materials flow. It governs the movement of ...

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 ...

You may be familiar with a common science demonstration done in classrooms: If you mix cornstarch and water together in the right proportions, you create a gooey material that seems to defy the rules ...

A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to ...
