All Stories by Carolyn Gramling

  1. Grand Canyon

    Soil eroded by glaciers may have kick-started plate tectonics

    How plate tectonics got going is a mystery. Now scientists say they’ve found a key part of the story: massive piles of sediment dumped in the ocean.

  2. Diplodocus in Smithsonian fossil hall
    Science & Society

    The Smithsonian’s ‘Deep Time’ exhibit gives dinosaurs new life

    The Smithsonian’s renovated fossil hall puts ancient dinosaurs and other creatures in context.

  3. tufted puffin

    Thousands of birds perished in the Bering Sea. Arctic warming may be to blame

    A mass die-off of puffins and other seabirds in the Bering Sea is probably linked to climate change, scientists say.

  4. Zanskar River in Himalayan mountains

    Himalayan glacier melting threatens water security for millions of people

    Asia’s glaciers are melting faster than they are accumulating new stores of snow and ice.

  5. Tableau Physique

    This iconic Humboldt map may need crucial updates

    A seminal, 212-year-old diagram of Andean plants by German explorer Alexander von Humboldt is still groundbreaking — but outdated, researchers say.

  6. red pigment in mouse fossil

    Signs of red pigment were spotted in a fossil for the first time

    For the first time, scientists have identified the chemical fingerprint of red pigment in a fossil.

  7. Apollo mission
    Planetary Science

    Apollo-era moonquakes reveal that the moon may be tectonically active

    Moonquakes recorded decades ago suggest the moon is tectonically active. Knowing more about that activity could help scientists identify where to land future spacecraft.

  8. Coco River in Brazil

    Only a third of Earth’s longest rivers still run free

    Mapping millions of kilometers of waterways shows that just 37 percent of rivers longer than 1,000 kilometers remain unchained by human activities.

  9. golden toad

    1 million species are under threat. Here are 5 ways we speed up extinctions

    One million of the world’s plant and animal species are now under threat of extinction, a new report finds.

  10. flamingo lagoon

    The search for new geologic sources of lithium could power a clean future

    Futuristic clean-energy visions of electric vehicles are driving the hunt for lithium.

  11. Corey Ford/Alamy

    A dinosaur’s running gait may reveal insights into the history of bird flight

    In what may have been a precursor to avian flight, a flightless winged dinosaur may have flapped its wings as it jogged.

  12. hippo

    Hippo poop cycles silicon through the East African environment

    By chowing down on grass and then excreting into rivers and lakes, hippos play a big role in transporting a nutrient crucial to the food web.
