With up to a million X-ray flashes per second, 8,000 times more than its predecessor, it transforms the ability of scientists to explore atomic-scale, ultrafast phenomena that are key to a broad range of applications, from quantum materials to clean...

A molecule with hooks that can grip and disable the virus’s pesky protease shows potential for fighting infection.

Researchers used cryo-EM (left) to discover how a chamber in human cells (right) directs protein folding. 

Powerful X-rays from SLAC’s synchrotron reveal that our immune system’s primary wiring seems to be no match for a brutal SARS-CoV-2 protein.

After almost two decades of synchrotron experiments, Caltech scientists have captured a clear picture of a cell’s nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell’s nucleus...

Researchers discover that a spot of molecular glue and a timely twist help a bacterial enzyme convert carbon dioxide into carbon compounds 20 times faster than plant enzymes do during photosynthesis. The results stand to accelerate progress toward converting carbon...

Sandwiching wiggly proteins between two other layers allows scientists to get the most detailed images yet of a protein that’s key to the spread of acute myeloid leukemia.

SLAC and Stanford scientists used it to zoom in on an iconic RNA catalyst and a piece of viral RNA that’s a potential target for COVID-19 treatments.

G6PD deficiency affects about 400M people worldwide and can pose serious health risks. Uncovering the causes of the most severe cases could finally lead to treatments.

The study, done on a mild-mannered relative of the virus that causes COVID-19, paves the way for seeing more clearly how spike proteins initiate infections, with an eye to preventing and treating them.

No human cell can function without these tiny machines, which cause disease when they go haywire and offer potential targets for therapeutic drugs.
