Mounting evidence suggests neutrinos are key to why antimatter is rare
The source of matter’s dominance over antimatter might be revealed by the tiny subatomic particles.

Physicists have found quasiparticles that mimic hypothetical dark matter axions
These subatomic particles could make up dark matter in the cosmos. A mathematically similar phenomenon occurs in a solid material.

A new experiment slashes the maximum possible mass of tiny neutrinos
The KATRIN experiment suggests that the tiny subatomic particles have masses a minuscule fraction of an electron’s.

How an astrophysicist chased a star from the Halo games to real life
Julián Alvarado Gómez has devoted his career to a star called Iota Horologii. His former life as a Halo video gamer helps fuel that devotion.

How a 2017 radioactive plume may be tied to Russia and nixed neutrino research
A botched attempt at producing radioactive material needed for a neutrino experiment may have released ruthenium-106 to the atmosphere in 2017.

Dark matter particles won’t kill you. If they could, they would have already
The fact that no one has been killed by shots of dark matter suggests the mysterious substance is relatively small and light.

The highest-energy photons ever seen hail from the Crab Nebula
An experiment in Tibet spotted photons with over 100 trillion electron volts of energy.

Diamond detectors could aid the search for dark matter
Elusive dark matter particles could be spotted when they slam into electrons or atomic nuclei within diamond, scientists say.

Physicists have finally figured out how pentaquarks are built
The particles are made of up two smaller particles, stuck together like atoms in a molecule.

An experiment hints at quantum entanglement inside protons
Particles inside protons seem to be linked on a scale smaller than a trillionth of a millimeter.

This is the slowest radioactive decay ever spotted
Scientists have made the first direct observations of an exotic type of radioactive decay called two-neutrino double electron capture.

How a proton gets its spin is surprisingly complicated
Pinning down the source of protons’ spin is surprisingly hard to do.
