Scientists have improved their ability to detect underground nuclear explosions set off  by rogue nations,  a development sure to be of interest next week, when the Nuclear Security Summit kicks off its 2016 meeting in Washington D.C.

A team led by Charles R. Carrigan at Lawrence Livermore National Laboratory (LLNL) used field experiments to build a new, complex model that predicts isotopic ratios of noble gases that would be released from such explosions . . .
