Elements 115 and 113 discovered in Dubna
3 February 2004

A team of Russian and American physicists that discovered elements 114 and 116 in 1998 and 2000 now believe they may have created two other superheavy elements - 113 and 115. If confirmed, these results would lend even more weight to the idea of an "island of stability" at the edge of the periodic table (Y Oganessian et al. 2003 Phys. Rev. C 69 021601)
