Researchers have directly visualized a rare type of chemical bond between some of the heaviest elements in the periodic table, providing experimental evidence of how these atoms share electrons in ...

Researchers at the University of Manchester in the UK have directly visualized thorium-thorium bonding, ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite ...

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form ...

(koto_feja/Getty Images) A breakthrough in chronometry decades in the making could redefine the limits of how we keep time.

First dreamed up decades ago, the world's first nuclear clocks are set to improve quickly, becoming more precise and aiding the hunt for dark matter.

For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons ...

Raising the energy state of an atom’s nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, ...
