A half-mile-long stretch of tunnel in Menlo Park, California is now colder than most of the universe.
This illustration shows snapshots of the light-triggered transition of the ring-shaped 1,3-cyclohexadiene (CHD) molecule (background) to its stretched-out 1,3,5-hexatriene (HT) form (foreground).
An animation shows how an infrared laser beam (orange) triggers atomic vibrations in a thin layer of iron selenide, which are then recorded by...
X-ray laser pulses probe water droplets like these to discover water’s hidden (and sometimes bizarre) properties.
Studies of atomic-level processes that drain battery life and efficiency help improve battery performance.
Ultra-bright X-ray laser pulses can be used to strip electrons away from atoms, creating ions with strong charges.
At LCLS, crystallized ribosomes travel through a capillary into the interaction region, where they are zapped with a beam of X-rays.
Researchers used SLAC’s ultrafast electron diffraction (UED) as an electron camera to take snapshots of a three-atom-thick layer of a promising material as it...
