Direct photons point to positive gluon polarization

A new publication by the PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC) provides definitive evidence that gluon "spins" are aligned in the same direction as the spin of the proton they're in. The result, ...

What coffee with cream can teach us about quantum physics

Add a dash of creamer to your morning coffee, and clouds of white liquid will swirl around your cup. But give it a few seconds, and those swirls will disappear, leaving you with an ordinary mug of brown liquid.

Using machine learning to better understand how water behaves

Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100C, water might be able to separate into two liquid phases of different densities. ...

How stiff is the proton?

The proton is a composite particle made up of fundamental building blocks of quarks and gluons. These components and their interactions determine the proton's structure, including its electrical charges and currents. This ...

Skepticism about Microsoft results regarding robust quantum bits

In March 2022, Microsoft published research results about the realization of a special type of particle that might be used to make particularly robust quantum bits. Researchers at the University of Basel are now calling these ...
