The standard model of particle physics passed one of its strictest tests yet
An experiment with a single electron, trapped for months on end, produced one of the most precise tests yet of the standard model of particle physics.

50 years ago, physicists found the speed of light
In the 1970s, scientists set a new maximum speed limit for light. Fifty years later, they continue putting light through its paces.

How ghostly neutrinos could explain the universe’s matter mystery
If neutrinos behave differently from their antimatter counterparts, it could help explain why our cosmos is full of stuff.

50 years ago, physicists got a whiff of what glues together protons
In 1972, particle smashups hinted at the gluon, which we now know not only holds together the innards of the proton, but also makes up more than a third of its mass.

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.

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.

A new dark matter experiment quashed earlier hints of new particles
Unlike its earlier incarnation, the XENONnT detector found no evidence of extra blips that scientists had hoped indicated new physics.

A supersensitive dark matter search found no signs of the substance — yet
The LZ experiment’s first measurement raises hopes that scientists are closer than ever to finding the source of much of the universe’s mass.

How neutrinos could ensure a submarine’s nuclear fuel isn’t weaponized
Nuclear submarines could be monitored with the help of neutrinos to ensure that the fuel isn’t diverted to nuclear weapons programs
