Scientists Watch Bacterial Sensor Respond to Light

A number of important biological processes, such as photosynthesis and vision, depend on light. But it’s hard to capture responses of biomolecules to light because they happen almost instantaneously.

Now, researchers have made a giant leap forward in taking snapshots of these ultrafast...
