The inside of a proton endures more pressure than anything else we’ve seen
For the first time, scientists used experimental data to estimate the pressure inside a proton.
- Particle Physics
The proton’s weak side is just as feeble as physicists thought
Scientists make the most precise measurement yet of the proton’s weak charge and find it agrees with predictions.

The quest to identify the nature of the neutrino’s alter ego is heating up
The search is on for a rare nuclear decay that could prove neutrinos are their own antiparticles and shed light on the universe’s antimatter mystery.
- Astronomy
Universes with no weak force might still have stars and life
An alternate universe that lacks one of the four fundamental forces might still have galaxies, stars, planets and perhaps life, a new study suggests.
- Particle Physics
Clumps of dark matter could be lurking undetected in our galaxy
Dark matter, assumed to form featureless blobs, might clump together into smaller objects.
- Astronomy
Mysterious high-energy particles could come from black hole jets
Three types of high-energy cosmic particles could all have the same source: black holes in galaxy clusters.
- Particle Physics
Magnets with a single pole are still giving physicists the slip
Using data from particle accelerators and dead stars, scientists eliminate some possible masses for magnetic monopoles.
