Using a new state-of-the-art atomic force microscope, scientists at UC Berkeley were able to capture the first images of a molecule just before and after it reacts. The images show the molecule's structure in detail, even the bonds connecting atoms. Until now, scientists have only been able to infer this type of information.

The series of images on the left side (labeled A) show the molecule before, while the images on the right (labeled B) display the after.
