    How biology breaks the ‘cerebral mystique’

    The Biological Mind rejects the idea of the brain as the lone organ that makes us who we are. Our body and environment also factor in, Alan Jasanoff says.

  2. Ptiloris paradiseus
    Animals

    Why some birds of paradise have ultrablack feathers

    Birds of paradise have superblack feathers because of tilted, spiky microscopic features in their feathers.

    Planetary Science

    See a new mosaic of images of comet 67P from the Rosetta mission

    A montage of images taken by the Rosetta spacecraft and its lander, Philae, recap the daring mission to comet 67P.

    Scientists create the most cubic form of ice crystals yet

    Ice has taken on a strange structure, with its water molecules arranged in nearly perfect cubes.

  9. Planetary Science

    Mars has nighttime snow storms

    When clouds of water-ice particles cool at night, snow starts to fall rapidly on Mars, simulations suggest. The squalls could explain observations made by the Phoenix lander in 2008.

    Planetary Science

    Moon had a magnetic field for at least a billion years longer than thought

    The moon’s magnetic field could have lasted until about a billion years ago.

    Climate

    South Asia could face deadly heat and humidity by the end of this century

    If climate change is left unchecked, simulations show extreme heat waves in densely populated agricultural regions of India and Pakistan.
