This environmentally friendly quantum sensor runs on sunlight
Quantum sensors often rely on power-hungry lasers to make measurements. A new quantum magnetometer uses sunlight to measure magnetic fields instead.

Falling objects in orbit show Einstein was right — again
For more than two years, a pair of metal cylinders fell at the same rate in space, confirming the equivalence principle, a key tenet of general relativity.

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.

Physicists dispute a claim of detecting a black hole’s ‘photon ring’
A thin ring of light around a black hole, which would probe gravity in a new way, has been found, one team claims. Skeptics aren’t convinced.

‘Chameleon’ forces remain elusive in a new dark energy experiment
A hypothetical fifth force associated with “chameleon” dark energy and that morphs based on its environment didn’t turn up in a sensitive experiment.
