Theory and experiment combine to shine a new light on proton spin

Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a new method that combines experimental data with state-of-the-art calculations has revealed a more detailed picture of spin contributions ...

Atomic-resolution imaging shows why ice is so slippery

A team of physicists affiliated with several institutions in China has uncovered the reason behind the slipperiness of ice. In their study, published in the journal Nature, the group used atomic force microscopy to get a ...
