Scientists Create Di-positronium Molecules

doxology writes "The BBC reports that scientists have been able to create di-positronium molecules. A di-positronium molecule consists of two positronium atoms, exotic atoms which are made from an electron and a positron (the anti-particle of the electron). A potential use of these molecules is to make extremely powerful gamma-ray lasers, possibly on sharks."

"Putting one on a satellite and blasting ICBMs in orbit, however, could be a very different story"

I doubt it. If you can't focus the bean, you don't have much chance of using it at distance.
