Following on from CB's post above on computing, new technology allows scientists to cool atoms and then glue them together somehow.

The method is called photoassociation: two atoms are merged using lasers to induce a chemical bond between them, forming a molecule. These molecules may contain two of the same types of atoms -- making them homonuclear -- or they can contain two different types of atoms, heteronuclear, such as the case with the lithium-rubidium molecules created by the team.
Again way above my head but sounds promising perhaps!
