Researchers have discovered a new way to help liquid flow in only one direction, but without using the flaps that engines and our circulatory system rely upon to prevent fluid backup. The team created ...

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in only one direction, making them essential for tasks like rectification, ...

Flaps perform essential jobs. From pumping hearts to revving engines, flaps help fluid flow in one direction. Without them, keeping liquids going in the right direction is challenging to do.
