Superbright and fast X-rays image single layer of proteins

In biology, a protein’s shape is key to understanding how it causes disease or toxicity. Researchers who use X-rays to takes snapshots of proteins need a billion copies of the same protein stacked and packed into a neat crystal. Now, scientists using exceptionally bright and fast X-rays can take a picture that rivals conventional methods with a sheet of proteins just one protein molecule thick.
