First antimatter chemical reaction

There am leido in Astroseti that scientists of the CERN have been able to combine antiprotons with hydrions producing the first chemical reaction matter-antimatter of history. This represents the first chemical reaction matter-antimatter, if the interaction of positrons with the ordinary matter is not counted. Previously helium atom antiprotons had been inserted but this really did not constitute chemical since the antiprotons only replaced an electron in the helium atom.

I have not been able to avoid to remember to the book Angels and Demons of polemic Dan Brown. The image is ambigrama created by John Langdon.
