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."

On the good side

As a result, there is a huge interest in the technology from the military as well as energy researchers who believe the lasers could be used to kick-start nuclear fusion in a reactor.

Well, I'm not sure if letting the military get their hands on it is such a good thing, but the use to initiate nuclear fusion could be the key to cleaner power for everyone. The hardest part of initiating fusion has been pouring enough energy in to start the reaction and allow it to become self-sustaining. This discovery might lead to technology capable of generating the necessary energy.

Atoms?

So positronium is an atom composed of an electron and a positron. Is this then an atom without a nucleus?

Weird.
