An artist's rendering of a protein reacting to light

Scientists have been able to capture the highest resolution image of a protein using an X-ray laser ever.

This picture was taken using a Linac Coherent Light Source (LCLS) with lasers that are about one billion times brighter than conventional X-rays and allowed the team to understand changes to the protein within millionths of a second of it being exposed to light - an important breakthrough.

Proteins, known as the "molecules of life", are present in all the chemical reactions that take place in the human body, according to the Lawrence Livermore National Laboratory who helped carry out the research.

These results establish that we can use this same method with all kinds of biological molecules, including medically and pharmaceutically important proteins.

We are on the verge of opening up a whole new unexplored territory in biology, where we can study small but important reactions at ultrafast timescales.
