Charles Darwin worried that the fossil record looked strangely abrupt, with complex animals appearing in a geological instant instead of gradually unfolding over deep time. A new idea about how ...

Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...

Time on Mars does not match time on Earth, and the difference is no longer a thought experiment. Precision calculations now show that clocks on the red planet tick measurably faster, confirming a ...

Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...
