Biomolecules imaged at record-breaking resolution using localization atomic force microscopy
This is an article  from Physics World. We now have the ability to take really detailed images of molecules. This is really important, if not rather complex but we have made huge progress in this. Should aid study of molecules and perhaps open up new fields of research.
Back in 1989 IBM made their logo from Xenon atoms . So I guess this shows how much progress we have made since then.
