Capturing the coordinated dance between electrons and nuclei in a light-excited molecule

Using a high-speed "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, scientists have simultaneously captured the movements of electrons and nuclei in a molecule after it was excited with ...

Electrons break rotational symmetry in exotic low-temp superconductor

Scientists have discovered that the transport of electronic charge in a metallic superconductor containing strontium, ruthenium, and oxygen breaks the rotational symmetry of the underlying crystal lattice. The strontium ruthenate ...

Probing materials at deep-Earth conditions to decipher Earth's evolutionary tale

Far below the Earth's surface, about 1,800 miles deep, lies a roiling magmatic region sandwiched between the solid silicate-based mantle and molten iron-rich core: The core-mantle boundary. It's a remnant of olden times, ...

True colors: Using X-rays to trace the evolution of insects' structural colors

Many colors in nature are produced using pigments that absorb light to varying degrees and reflect the rest, creating shades of red and brown, for instance. Our clothes and other objects are colored the same way, using chemical ...
