Capillary suspensions are defined by a small volume of an immiscible secondary fluid introduced to a particle–fluid suspension, triggering the formation of liquid bridges that interconnect particles ...

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have ...

Artificial tissues can mimic muscle, liver, kidney and skin, but they still face a basic survival problem: cells need blood vessels. Without a dense vascular network, oxygen and nutrients cannot ...
