Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

Researchers at the UK’s National Physical Laboratory (NPL) have created a tiny atomic fountain clock. It is only 5 percent the size of a normal one but keeps the same high-precision time. The clock’s ...

Atomic scientists set their "Doomsday Clock" on Tuesday closer than ever to midnight, citing aggressive behavior by nuclear powers Russia, China and the United States, fraying nuclear arms control, ...

A Chicago-based group of scientists have once again warned the world is closer than ever to human-made destruction by moving the symbolic “Doomsday Clock” up to 85 seconds to midnight.

At the dawn of the nuclear age, scientists created the Doomsday Clock as a symbolic representation of how close humanity is to destroying the world. On Tuesday, nearly eight decades later, the clock ...
