Nuclear physicist's voyage towards a mythical island
Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived atomic nuclei could give rise to a so-called ''island of stability'' far beyond the element uranium. However, a new study, led by nuclear physicists at Lund University, shows that a 50-year-old nuclear physics manifesto must now be revised. (2021-01-26)

Nuclear war could trigger big El Niño and decrease seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy - at least in the equatorial Pacific.
