The molecular hydrogen ion H₂⁺ is the simplest molecule. This simplicity makes it a perfect study object for physicists, as ...

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe. By Katrina Miller Katrina Miller studied neutrinos in graduate school, but ...

Negative mass was something physicists never thought they would find – let alone create. For more than a century, physics has operated on the foundation that mass is always positive. From Newton’s ...

All the tech we rely on, from cars to smartphones, was engineered using physics. You don’t need to know the science to use these things. But a well-rounded human should understand at least some of the ...

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...

For three decades, researchers hunted in vain for new elementary particles that would have explained why nature looks the way it does. As physicists confront that failure, they’re reexamining a ...
