Researchers at SLAC’s LCLS-II facility use an ultrafast, powerful X-ray laser to record “molecular movies” in real time. By firing extremely short femtosecond pulses, the system captures how electrons move and how chemical reactions unfold, allowing scientists to observe processes as they happen rather than only after the fact.
Both outlets describe tours and explanations of how the facility works and what scientists can see with it. CNET emphasizes the connection between the laser’s ability to produce ultrafast femtosecond pulses and the resulting images of molecular motion. Mashable also focuses on the same core capability—real-time molecular movies from the LCLS facility—framed as an inside look at the world’s most powerful X-ray laser. While they both highlight the science of recording dynamic reactions, neither provides detailed results beyond describing the mechanism and purpose.
