    Zapping plastic with a laser forged tiny diamonds

    The technique could be used to manufacture nanodiamonds for use in quantum devices and other applications.

    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.

  3. Physics

    ‘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.

    Sea urchin skeletons’ splendid patterns may strengthen their structure

    “Voronoi” geometric patterns found in sea urchin skeletons yield strong yet lightweight structures that could inspire the creation of new materials.

  5. Particle Physics

    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.

  6. Physics

    Spiraling footballs wobble at one of two specific frequencies

    Researchers simulated the path of a flying football to study how pigskins wobble and why they drift sideways.

  7. Particle Physics

    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.

  8. Cosmology

    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.

  9. Physics

    Two black holes merged despite being born far apart in space

    A closer look at gravitational wave data reveals 10 overlooked mergers, including one between black holes that probably found each other late in life.

    This stick-on ultrasound patch could let you watch your own heart beat

    A new, coin-sized ultrasound probe can stick to the skin like a Band-Aid for up to two days straight, marking a milestone in personalized medicine.

  11. Space

    Amateur astronomers’ images of a rare double aurora may unlock its secrets

    With breathtaking videos, citizen scientists have shown researchers a new pattern of auroras that may solve the mystery behind a strange red glow.

  12. Quantum Physics

    Quantum entanglement makes quantum communication even more secure

    Bell tests proved that quantum mechanics really is “spooky.” Now they’ve made quantum communication even more hacker-proof.
