An anonymous reader writes: The italian economic journal "Il sole 24 ore" published an article about a successful cold fusion experiment performed by Yoshiaki Arata in Japan. They seems to have pumped high pressure deutherium gas in a nanometric matrix of palladium and zyrcon oxide. The experiments generates a considerable amount of energy and they found the presence of Elium-4 in the matrix ( as sign of the fusion ). Here are the articles: first second( in italian ). I was not able to found other articles about this but the journal is very authoritative in Italy. Google translations: first, second.
