Some of the world's most eminent scientists are about to announce whether the world is closer to oblivion than it ever was before.
The Bulletin of the Atomic Scientists – a group of leading thinkers convened after the creation of the nuclear bomb – is set to announce whether it will reset the "Doomsday Clock". That clock is a way of showing just how at risk humanity is of apocalypse from nuclear warfare, climate change or a range of other threats.
The clock counts forward to midnight, or oblivion. It currently stands at three minutes to midnight, which is most at-risk humanity has been since the height of the Cold War.
The announcement will begin at 1.30pm eastern time, or 6.30pm in the UK.

The event will be hosted by speakers including:
