Compact electron accelerator reaches new speeds with nothing but light

An image from a simulation in which a laser pulse (red) drives a plasma wave, accelerating electrons in its wake. The bright yellow spot is the area with the highest concentration of electrons. In an experiment, scientists used this technique to accelerate electrons to nearly the speed of light over a span of just 20 …

Scientists Reveal The First Images of Atoms ‘Swimming’ in Liquid

The motion of single atoms through liquid has been caught on camera for the first time. Using a sandwich of materials so thin they’re effectively two-dimensional, scientists trapped and observed platinum atoms ‘swimming’ along a surface under different pressures. The results will help us better understand how the presence of liquid alters the behavior of …
