    US scientists have confirmed the discovery of element number 114, first made over a decade ago by a team in Russia. By smashing a high energy beam of calcium-48 ions into a plutonium-242 target, the US team managed to detect two nuclei of element 114, which is predicted by some to be bordering the so-called 'island of stability' for superheavy atoms.Yuri Oganessian and his team at Dubna, Russia, were the first to claim to have created nuclei of element 114 - but any such claim has to be thoroughly verified and the experiments repeated independently before the element can be considered for admission...
