Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become ...
Physicists from Germany, Denmark, and Austria have succeeded in creating a kind of turnstile for light in glass fibers that allows the light particles to only pass through one at a time

Light exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and knock out an electron, the molecule flies ...
