What you're looking at above is the exact moment that atoms for a covalent bond. It's the first time this intricate single-molecule transformation has been captured in the act. It's a breakthrough, it's informative, in many ways it's beautiful. And it was taken by sheer dumb luck.
As reported in this week's Science Felix Fischer and his team at the Department of Energy’s Lawrence Berkeley National Laboratory had set out to do what any enterprising young molecular chemist is doing these days: Create nanostructures made out of graphene, the wondermaterial of our times.
