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.

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.

Clumps of dark matter could be lurking undetected in our galaxy
Dark matter, assumed to form featureless blobs, might clump together into smaller objects.

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.

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.

Ultrahigh energy cosmic rays come from outside the Milky Way
The biggest cosmic ray haul ever points toward other galaxies as the source of the rays, not our own.

The sun’s strongest flare in 11 years might help explain a solar paradox
The sun tends to release its biggest flares at the ends of solar cycles — and we might finally be able to test why.
