Engineers reinvent the 5,000-year-old gear using fluids instead of solid teeth.
A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The ...

They used sound to lift stones - was this the secret to the pyramids?
Ancient civilizations moved stones weighing hundreds of tons without cranes, pulleys, or modern machines. One theory? They used sound. And shockingly, science now shows acoustic levitation is real — ...
Abstract: Current signal processing algorithms excel at impairment compensation when the parameters of optical fiber systems are precisely defined. However, their effectiveness diminishes considerably ...
Abstract: Current non-destructive tomography sensing systems, particularly in the domain of eddy current sensing, lack the capability to dynamically and intelligently optimize sensing parameters in ...
Far from the Sun’s heat, orbiting the outer planets of the solar system, are moons with oceans of liquid water beneath their frozen surfaces. Keith Cooper finds out how planetary scientists are ...

The simplest self-braking pulley
A hands-on physics experiment demonstrates how a basic self-braking pulley works, explaining the forces and friction that allow it to stop itself without extra mechanisms. New Objects Detected in ...
