Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy without a parent star, turning a once purely theoretical class of worlds into a ...

The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, ...

At the University of Oxford, Justin Benesch studies assemblies made between proteins called molecular chaperones and the proteins they protect in cells. These assemblies slow the formation of amyloid ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

Scientists at the Institute of Modern Physics (lMP) of the Chinese Academy of Sciences (CAS) and their collaborators have demonstrated the effectiveness of an innovative nuclear mass measurement ...

Automated mass photometry combines the unparalleled simplicity and sensitivity of Refeyn’s molecular mass measurement technology with the efficiency and ease of automation. This approach offers ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

This graphic shows how microlensing was used to measure the mass of a white dwarf star. The dwarf, called LAWD 37, is a burned-out star in the center of this Hubble Space Telescope image. Credits: ...

Scientists have achieved the most precise measurement to date of the mass of the W boson, one of nature's force-carrying particles. The measured value shows tension with the value expected based on ...

Precise values for the masses of the nuclei of the simplest atoms, such as hydrogen and helium, are crucial for experiments targeting big unsolved problems in physics. A technique known as ...

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 ...
