  9. photo of Thwaites Glacier
    Climate

    Antarctica’s Thwaites Glacier ice shelf could collapse within five years

    The loss of Thwaites’ buttressing ice shelf could hasten the demise of the “Doomsday Glacier” and raise the risk of dramatic sea level rise.

    Paleontology

    Mammoths may have gone extinct much earlier than DNA suggests

    Ancient DNA in sediments may be leading paleontologists astray in attempts to figure out when woolly mammoths and woolly rhinos died out, a new study argues.

  11. Glassy debris creates the bluish tinge and radiating black stripes around an impact crater on Mars
    Planetary Science

    Asteroid impacts might have created some of Mars’ sand

    Roughly a quarter of the Red Planet’s sand is spherical bits of glass forged in violent impacts, new observations reveal.
