    Tooth plaque shows drinking milk goes back 3,000 years in Mongolia

    The hardened plaque on teeth is helping scientists trace the history of dairying in Mongolia.

  2. Greenland ice sheet

    Greenland may have another massive crater hiding under its ice

    There may be yet another large crater buried beneath Greenland’s ice sheet. But it’s probably not related to the first one found last year.

  3. larsen c and iceberg A68

    An Antarctic expedition will search for what lived under the Larsen C ice shelf

    The fourth attempt to investigate the seafloor once hidden by the Larsen C iceberg may have the best chance yet of success.

  4. a photo of the Stange ice shelf

    Collapsing ice cliffs may not contribute to sea level rise

    Scientists debate a controversial hypothesis that suggests that massive crumbling ice cliffs could speed up future sea level rise.

  5. James Balog

    ‘The Human Element’ makes the impacts of climate change feel real

    Photographer James Balog puts a human face on the impacts of climate change in the documentary The Human Element.

  6. researchers in Prince Christian Sound

    Climate change might not slow ocean circulation as much as thought

    New measurements may call for a rethink of what controls ocean circulation in the North Atlantic.

  7. Earth's magnetic field

    Earth’s core may have hardened just in time to save its magnetic field

    Earth’s inner core began to solidify sometime after 565 million years ago — just in time to prevent the collapse of the planet’s magnetic field, a study finds.

  8. ancient marine reptile

    Tiny eyes make a bizarre, ancient platypus-like reptile even weirder

    An ancient oddball marine reptile had teeny-tiny eyes, suggesting it probably used senses other than sight to catch food.

  9. tetrapod robot

    A four-legged robot hints at how ancient tetrapods walked

    Using fossils, computer simulations and a life-size walking robot, researchers re-created how an early tetrapod may have made tracks.

  10. British Antarctic Survey’s Skytrain Ice Rise site

    A drill built for Mars is being used to bore into Antarctic bedrock

    An autonomous drill originally designed for work on Mars has its first mission in Antarctica.

  11. pterosaur illustration

    Pterosaurs may have been covered in fur and primitive feathers

    A new study provides evidence of plumelike structures in ancient flying reptiles.

  12. hurricane flooding

    Half a degree stole the climate spotlight in 2018

    Climate attribution studies and new data on global warming targets put climate change in the spotlight this year.
