TLDR

Lifeboat News reports that SLAC researchers measured the shortest high-energy X-ray pulses recorded at an X-ray free-electron laser. A study author said the pulses are fast enough to record electronic motion. Interesting Engineering also describes record-breaking X-rays focused into a spot 100,000 times smaller than a hair.
