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.

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.
