When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

A strange molecular pattern, first mistaken for an error, led researchers to an unexpected discovery: molecules forming ...

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this 'Einstein problem' was discovered for the first time.
