In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...

A chemical element is one of those squares on the periodic table that adorns many a classroom wall. Sure. But what is an element really? It is a more subtle question that you might realise. To get to ...
