Scientists used SLAC's LCLS X-ray laser to make the first snapshots of a chemical interaction between two biomolecules. It changes the shape of millions of molecular switches almost instantaneously, like synchronized swimmers performing the same move.

High-speed X-ray camera reveals ultrafast atomic motions at the root of organisms’ ability to turn light into biological function.

New insights into how bacteria interact with host cells could help fight off harmful microbes.

Scientists have determined in atomic detail how a potential drug molecule fits into and blocks a channel in cell membranes that Ebola and related “filoviruses” need to infect victims’ cells.

Ian Wilson explains how scientists have found a way to induce antibodies to fight a range of influenza viruses, which could some day eliminate the need for seasonal flu shots.

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

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

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.

Developed at SLAC’s LCLS, it could also yield new information from hard-to-study samples in materials science, chemistry and other fields.

An X-ray laser experiment could lead to new drugs that lessen the side effects caused by powerful painkillers like morphine.

Research reveals that the bacterial immune system can better destroy viral attackers by saving genetic records of previously encountered viruses.
