    Earth’s inner core may be reversing its rotation

    In the past 13 years, the rotation of the planet’s solid inner core may have temporarily stopped and then started to reverse direction.

  12. An Amami rabbit sitting on the ground.

    A rare rabbit plays an important ecological role by spreading seeds

    Rabbits aren’t thought of as seed dispersers, but the Amami rabbit of Japan has now been recorded munching on a plant’s seeds and pooping them out.
