Atomic scientists have reset the “Doomsday Clock,” moving its hands from 90 seconds to 89 seconds to midnight — symbolising how close they deem the world is to ending. Midnight marks the theoretical point of annihilation.

Each year, atomic scientists move the hands of the clock closer to — or further away from — midnight based on "existential" risks to Earth and humanity such as nuclear war and climate change, as well as disruptive technologies such as artificial intelligence and emerging biotechnology.
