  • Written in bone

    Researchers are reconstructing the migrations that carried agriculture into Europe by analyzing DNA from the skeletons of early farmers and the people they displaced.

  • Europa

    The ice of a distant moon

    Jupiter’s moon Europa hides a liquid ocean, and conceivably life, under kilometers of ice. The challenge for engineers is how to penetrate that frozen barrier with technology that can be launched into space and operated remotely.
