In two new papers, researchers used X-ray crystallography and cryogenic electron microscopy to reveal new details of the structure and function of molecular assembly lines that produce common antibiotics.

Four complementary analyses by Fermilab’s MicroBooNE show no signs of a theorized fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments.

Topological insulators conduct electricity on their surfaces but not through their interiors. SLAC scientists discovered that high harmonic generation produces a unique signature from the topological surface.

The results could lead to a better understanding of reactions with vital roles in chemistry and biology.
