Sea Quark Surprise Reveals Deeper Complexity in Proton Spin Puzzle

Image - The proton spin puzzle: Scientists want to know how different constituents of the proton contribute to its spin, a fundamental property that plays a role in how these building blocks give rise to nearly all visible matter in the universe. Pieces of the puzzle include the orbital angular momentum of quarks and gluons (top left), gluon spin (top right) and quark and antiquark spin (bottom). The latest data from RHIC reveal that the antiquarks' contribution is more complex than previously thought. (Credit: Brookhaven National Laboratory)

Preparing for a New Tool to Study the ‘Glue That Binds Us All’

Image - At left is a 1980s conception of the structure of the proton, which is a positively charged particle found in atomic nuclei. At right is our current understanding of the various subatomic particles – including quarks, antiquarks, and gluons – that make up the proton and contribute to a fundamental property known as spin.

How to Escape a Black Hole: Simulations Provide New Clues to What’s Driving Powerful Plasma Jets

Image - This visualization of a general-relativistic collisionless plasma simulation shows the density of positrons near the event horizon of a rotating black hole. Plasma instabilities produce island-like structures in the region of intense electric current. (Credit: Kyle Parfrey et al./Berkeley Lab)
