NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...

Researchers control biofilm formation using optical traps

Biofilms—slimy layers formed when bacteria stick together on a surface—allow bacteria to shield themselves from extreme environments and even evade antibiotics. In a new study, researchers have shown that laser light ...

Observing macroscopic quantum effects in the dark

Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in a potential ...

Probing for THz radiation directly at the source

The search for and development of efficient terahertz (THz) sources is one of the major scientific goals of the 21st century. The THz region of the electromagnetic spectrum is composed of light frequencies in between the ...

Shining a light on NASA's deep space demo

NASA's Psyche mission launched on 13 October 2023 on a journey to explore what could be the exposed metallic core of an ancient planet.
