After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

When it comes to weighing elementary particles, a set of scales is not much use. The mass of the electron, for instance, is about 10-30 kg and can only be determined by relying on its mathematical ...

In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental ...

Physicists in Germany say they have made the world’s most precise measurement of the deuteron mass by comparing it to the mass of the carbon-12 nucleus. The new work, which was carried out by ...

There’s a lot more to the story of the Higgs boson than just one man named Higgs. Despite the appeal of the “lone genius” narrative, it’s rare that a discovery can be attributed solely to the work of ...
