New simulations suggest the Milky Way’s long-predicted collision with Andromeda might be less of a cosmic certainty than we thought. A massive marine heat wave in 2023 sent North Atlantic temperatures soaring—equal to two decades’ worth of typical warming—with weak winds and climate change largely to blame. And researchers reveal that the planet’s most abundant animals—nematodes—may use teamwork and tower-building to hitch rides to new homes.
