Per la prima volta è stato prodotto e intrappolato un fascio di atomi di antidrogeno. C'è riuscito il CERN di Ginevra, che segna un altro punto dopo la scoperta del bosone di Higgs.
Si rende così possibile osservare più da vicino i segreti della materia nella quale, come in uno specchio, le particelle hanno la stessa massa, ma opposta carica elettrica rispetto a quella ordinaria, e che potrebbe diventare una straordinaria fonte d'energia.
Il risultato è stato ottenuto nell'ambito dell'esperimento denominato ASACUSA, frutto di una collaborazione internazionale.
