Memories may be maintained in the brain through a mechanism familiar to any engineer — negative and positive feedback loops, according to researchers Sukbin Lim and Mark Goldman at the UC Davis Center ...

Engineers use feedback loops — typically negative feedback is more useful, but positive feedback is needed for oscillators.

Negative feedback is a universal control mechanism that lets a system's output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it ...

In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing ...

“The only way to discover the limits of the possible is to go beyond them into the impossible.” – Arthur C. Clarke Even worse: some of these laws go back decades with little to no effort to improve ...
