Q&A: How machine learning helps scientists hunt for particles, wrangle floppy proteins and speed discovery

At the Department of Energy’s SLAC National Accelerator Laboratory, machine learning is opening new avenues to advance the lab’s unique scientific facilities and research.

First direct look at how light excites electrons to kick off a chemical reaction

The first step in many light-driven chemical reactions, like the ones that power photosynthesis and human vision, is a shift in the arrangement of a molecule’s electrons as they absorb the light’s energy. Now scientists have directly observed this first step.

First detailed electronic study of new nickelate superconductor finds 3D metallic state

It represents an entirely new type of ground state for transition metal oxides, and opens new directions for experiments and theoretical studies of how superconductivity arises and how it can be optimized in this system and possibly in other compounds.
