Protons contain intrinsic charm quarks, a new study suggests
The massive quarks — counterintuitively heavier than the proton itself — might carry about 0.6 percent of a proton’s momentum.

Spiraling footballs wobble at one of two specific frequencies
Researchers simulated the path of a flying football to study how pigskins wobble and why they drift sideways.

Physicists spotted rare W boson trios at the Large Hadron Collider
By measuring how often triplets of particles called W bosons appear, scientists can check physics’ standard model for any cracks.

The Windchime experiment could use gravity to hunt for dark matter ‘wind’
Though decades away, the project hopes to use an array of ultrasensitive sensors as a “wind chime,” jostled by dark matter blowing past Earth.
