The synthesis of two new isotopes, osmium-160 and tungsten-156, by scientists at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators has provided new insights into nuclear structure and raised the possibility that lead-164 could be a doubly magic nucleus with enhanced stability.

Physicists Just Found The Lightest Known Form of Uranium, And It Has Unique Behaviors

Scientists have discovered a new type of uranium that is the lightest ever known. The discovery could reveal more about a weird alpha particle that gets ejected from certain radioactive elements as they decay.
The newfound uranium, called uranium-214, is an isotope, or a variant of the element, with 30 more neutrons than protons, one fewer neutron than the next-lightest known uranium isotope. Because neutrons have mass, uranium-214 is much lighter than more common uranium isotopes, including uranium-235, which is used in nuclear reactors and has 51 extra neutrons.
