Scientists just broke a textbook rule of physics

Scientists have defied a long-standing rule of laser physics by generating X-rays with much higher energies than conventional theory predicts. The surprising discovery reveals how two electrons working together can overcome a previously accepted limit, opening new possibilities f

CubeSat achieves challenging laser link to ground

Despite the complexity of the operation, ERMIS-3, an 8U CubeSat developed by the National and Kapodistrian University of Athens, has established a link with an optical ground station, marking an important step in validating optical communications on small satellites. The demonstr
