    Ants don’t make decisions on the move

    Worker ants stand still while processing environmental cues and planning their next moves, a new study suggests.

  5. Mount Etna
    Earth

    Succession of satellites keep eye on Earth

    50 years after plans were laid for the first Earth-observing spacecraft, the youngest Landsat satellites are still flying and imaging the planet’s surface.
