Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins align ...

Calculating a proton's spin used to be an easy college assignment. In fact, Carl Gagliardi remembers answering that question when he was a physics graduate student in the 1970s. But the real answer ...

A view inside a proton moving at nearly the speed of light toward the viewer with its spin pointing horizontally shows differences in the spatial distributions of the momentum of up (left) and down ...

As man voyages farther toward the stars, and faster across the face of his own earth, the instruments by which he steers become vastly more important. And on planes or ships or spacecraft, the heart ...

Protons play a central role in energy production within cells. A team of researchers has discovered that their movement is influenced by electron spin, a quantum property. This interaction occurs in ...

The famed collider at Brookhaven National Laboratory has ended operations, but if all goes to plan, a new collider will rise ...
