    The National Weather Service has launched its new U.S. forecasting model

    The United States has finally unveiled its new, highly touted weather prediction model, but some scientists worry that it’s not ready for prime time.

  2. 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.

    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.

  5. Zanskar River in Himalayan mountains
    Climate

    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.

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seminal, 212-year-old diagram of Andean plants by German explorer Alexander von Humboldt is still groundbreaking — but outdated, researchers say.

  7. red pigment in mouse fossil
    Paleontology

    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.

  8. 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.

  9. Coco River in Brazil
    Earth

    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.
