New data from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) add detail — and complexity — to an intriguing puzzle that scientists have been seeking to solve: how the building blocks that make up a proton contribute to its spin. The results reveal that different 'flavors' of antiquarks contribute differently to the proton's overall spin — and in a way that's opposite to those flavors' relative abundance.
