Black hole fashions stellar beads on a string

Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive ...

Quantum dark states lead to an advantage in noise reduction

While atomic clocks are already the most precise timekeeping devices in the universe, physicists are working hard to improve their accuracy even further. One way is by leveraging spin-squeezed states in clock atoms.

Early evolution of cicadas revealed by analyses of new fossils

To clarify the early evolutionary history of Cicadoidea fossils, the phylogenetic relationships between Mesozoic fossils and extant Cicadoidea, the macroevolution of body structure adaptations, and their relationship with ...

The tale of two clocks: Advancing the precision of timekeeping

Historically, JILA (a joint institute established by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) has been a world leader in precision timekeeping using optical atomic ...
