Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

New research findings show how higher viscosity, or resistance to flow, of the extracellular fluid that surrounds cells enables cancer cells to migrate more rapidly from a primary tumor to other sites ...

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey ...

To understand viscosity, laminar flow must be understood. This is when a gas or fluid flowing over a surface results in the molecules next to the surface having zero speed. As the distance from the ...

Rheology is the study of the flow and deformation of materials under applied forces, covering both liquids and solids. It examines how materials respond to stress, strain or flow, revealing ...
