All Stories by Davide Castelvecchi

  1. Physics

    Left in the cold

    An optical trap lets atoms in but not out, and it can be used to study matter at ultracold temperatures.

  2. Physics

    Life’s code in soap

    The mathematics of soapy water yields some clues to the origin of the genetic code.

  3. Physics

    Suction hunters

    Scientists reveal new details on how extendable jaws help fish capture prey.

  4. Chemistry

    Small, But Super

    These 'atoms' can't leap tall buildings in a single bound, but they have special powers.

  5. Physics

    Tight deadline

    Light behaves like waves or particles, but it doesn’t know what it will do in advance.

  6. Humans

    BOOK REVIEW | Naked in the Woods: Joseph Knowles and the Legacy of Frontier Fakery

    Review by Davide Castelvecchi.

  7. Chemistry

    Slippery when dry

    Surfaces that mimic the back of an African beetle can collect water from fog.

  8. Chemistry

    Phlegmatic molecules

    Time-lapse snapshots of molecules show that they change shapes less often than theory predicted.

  9. Space

    Neutron tie-dye

    Neutrons can produce 3-D scans of a magnetic field, even inside a solid.

  10. Health & Medicine

    Testing nanoparticles

    Testing the toxicity of dozens of nanoparticles en masse may offer a faster track to medical applications.

  11. Humans

    The undeciders

    A country’s development seems tied to the size of its executive cabinet, and a mathematical model helps explain why.

  12. Math

    Less is more

    Researchers have shown that a grip that’s too tight can be counterproductive, especially on a microscopic object — but the findings could apply to fields ranging from ecology to sociology.
