  1. Health & Medicine

    False teeth could double as hearing aids

    Dental implants can conduct sound through jawbone, making them candidates for discreet, high-quality hearing aids, researchers say.

  2. Quantum Physics

    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.

  3. Physics

    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.

  4. 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.

  5. 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.

  6. Health & Medicine

    Tiny amoebas move faster when carrying cargo than without

    A new study of the carrying capacity of single-celled amoebas may help scientists develop mini “trucks” to precisely target disease in the human body.

  7. Physics

    Why even small sonic booms are more annoying in cities

    Quieter sonic booms from next-generation planes could still be annoying in cities thanks to narrow streets and tall buildings, simulations suggest.

  8. Science & Society

    Growing wildfire threats loom over the birthplace of the atomic bomb

    Climate change is expected to make wildfires worse across much of the Southwest United States. A key nuclear weapons lab could be in the hot zone.

  9. Health & Medicine

    How to wash chicken in the kitchen more safely, according to physics

    Despite the advice of health experts, most people who cook chicken at home wash it. New research offers ways to reduce spreading dangerous germs.

  10. Plants

    Leonardo da Vinci’s rule for how trees branch was close, but wrong

    An update to da Vinci’s elegant, 500-year-old “rule of trees” offers a powerful, new way to describe the structure of almost any leafy tree.
