The first chemical reactions in the wake of the Big Bang have been recreated for the first time in conditions similar to those in the baby Universe. A team of physicists led by Florian Grussie of the ...

For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...

In Wednesday's issue of Nature, a new paper describes a potentially useful way of measuring the interactions between normal matter and exotic particles, like antiprotons and unstable items like kaons ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is ...

At temperatures below the depths of space just a few degrees above absolute zero researchers have replicated the universe’s first molecule, and the findings have turned conventional understanding of ...

Physicists at the Australian National University have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule – or 10-35 ...
