Scientists Discover Hidden Behavior in Water That Helps Explain Why Ice Floats
Around 70% of Earth’s surface is covered in water, a uniquely anomalous substance that often behaves differently compared…
Lasing of a cavity-based X-ray source
Shortly after the free-electron laser (FEL) concept was proposed in the 1970s11, the first FEL oscillator was developed12…
Coherent nonlinear X-ray four-photon interaction with core-shell electrons

XMM-Newton Offers Incredible X-ray View of Interstellar Comet 3I/ATLAS
Astronomers using ESA’s XMM-Newton observatory have captured an X-ray image of 3I/ATLAS, the third confirmed interstellar object to…
Self-compressed waveform-stable light transients enabling water-window attosecond spectroscopy
We first demonstrate the creation and field-resolved characterization of light transients, focusing on generating sub-cycle pulses. For this…
What happens when you cross the point of no return?
Black holes form when massive stars exhaust their nuclear fuel and collapse under their own gravity. This collapse…
