The two newest superheavy elements, elements 113 and 115, were recently discovered through a collaborative effort between scientists from the Glenn T. Seaborg Institute and the Chemistry and Materials Science Directorate at the Lawrence Livermore National Laboratory and researchers from the Joint Institute for Nuclear Research in Russia.
