The laws of physics have not always been symmetric, which may explain why you exist
For generations, physicists were sure the laws of physics were perfectly symmetric. Until they weren't.

A reflection always reproduces objects as a complete mirror image, rather than just its individual parts or individual parts in a completely different orientation. It's all or nothing, the mirror can't reflect just a little. ...

(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. ...
Precise information about the magnetic properties of nuclei is critical for studies of what's known as the 'weak force.' While people do not feel this force in the same way they feel electricity or gravity, its effects are ...

Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame. Measurements with ytterbium-174, an isotope with ...
