Researchers at SLAC have found a simple new way to study very delicate biological samples – like proteins at work in photosynthesis and components of protein-making machines called ribosomes – at the atomic scale using SLAC's X-ray laser.

X-ray research on 80-million-year-old fossilized burrows, likely the work of tiny marine worms, is helping scientists understand how living organisms affected the chemistry of the sea floor.

A tiny change in the length of a chemical bond makes a big difference in the activity of a molecule important in health, drug development and chemical synthesis

Using SLAC's X-ray laser, researchers have for the first time directly observed myoglobin move within quadrillionths of a second after a bond breaks and the protein releases a gas molecule.

A major international effort at SLAC is focused on improving our views of intact viruses, living bacteria and other tiny samples using the brightest X-ray light on Earth.

Graham George and Ingrid Pickering, a husband and wife X-ray research team, are co-leading a new study in Bangladesh to test whether selenium supplements can protect people from arsenic poisoning.

A biomedical breakthrough reveals never-before-seen details of the human body’s cellular switchboard that regulates sensory and hormonal responses.

Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled.

An experiment at SLAC’s X-ray laser provides new insight into the ultrafast motions of a muscle protein in a basic biochemical reaction.

A team led by Stanford University scientists is using software to breathe new life into results from past biological experiments at SLAC’s X-ray laser.

An experiment at SLAC's X-ray laser has revealed in atomic detail how a hypertension drug binds to a cellular receptor that plays a key role in regulating blood pressure.
