Amazing stuff!
"A team of nuclear physicists ... has discovered a previously unknown uranium isotope with atomic number 92 and mass 241. ...
it marks the first time since 1979 that a neutron-rich uranium isotope has been discovered. The researchers also calculated that uranium-241 likely has a half-life of just 40 minutes. ..."

From the abstract:
"The new isotope 241U was synthesized and systematic atomic mass measurements of nineteen neutron-rich Pa-Pu isotopes were performed in the multinucleon transfer reactions of the 238U+198Pt system at the KISS facility. The present experimental results demonstrate the crucial role of the multinucleon transfer reactions for accessing unexplored neutron-rich actinide isotopes toward the N=152 shell gap in this region of nuclides."
