  1. visualization of Alaska’s Yukon Delta

    A stunning visualization of Alaska’s Yukon Delta shows a land in transition

    Water and ice helped form the Yukon River’s delta. Now, climate change is reshaping it.

  2. illustration of flamingo-like flying dinosaurs, with two in the foreground and several in the background

    Pterosaurs may have been able to fly as soon as they hatched

    A fossil analysis shows the flying reptile hatchlings had a stronger bone crucial for lift-off that adults and shorter, broader wings for agility.

  3. close-up of wings of large banded grasshopper

    Insects had flashy, noise-making wings as early as 310 million years ago

    The structure of a grasshopper-like insect’s fossilized wing suggests it crackled and reflected light, perhaps to attract mates or warn off predators.

  4. a satellite photo of a hurricane over Central America

    Hurricanes may not be becoming more frequent, but they’re still more dangerous

    A new study suggests that there aren’t more hurricanes now than there were roughly 150 years ago.

  5. satellite images from before and after drainage of an ice-covered lake in Antarctica

    Satellites show how a massive lake in Antarctica vanished in days

    Within six days, an Antarctic lake with twice the volume of San Diego Bay drained away, leaving a deep sinkhole filled with fractured ice.

  6. a view to the tops of several tall, skinny trees with light green leaves

    Why planting tons of trees isn’t enough to solve climate change

    Massive projects need much more planning and follow-through to succeed – and other tree protections need to happen too.

  7. map of the heat wave that hit the Pacific Northwestern United States in June

    Human-driven climate change sent Pacific Northwest temperatures soaring

    As scientists dissect what pushed temperatures up to 5 degrees Celsius above previous records, they may have to revamp how to predict heat waves.

  8. black and white photo of a man in a cap with glasses leaning over a tabletop device while another man looks on

    A WWII submarine-hunting device helped prove the theory of plate tectonics

    With a boost from World War II, the fluxgate magnetometer became a portable and invaluable tool.

  9. Portland residents cooling off in the Oregon Convention Center

    3 things to know about the record-smashing heat wave baking the Pacific Northwest

    Road-buckling, cable-melting, life-threatening heat waves in the Pacific Northwest may become more common as global temperatures rise.

  10. illustration of a lizard sitting on a branch. shown is its head and neck with sap dripping down around it

    An ancient creature thought to be a teeny dinosaur turns out to be a lizard

    CT scans of hummingbird-sized specimens trapped in amber reveal that the 99-million-year-old fossils have a number of lizardlike features.

  11. photo of damage at a hydroelectric power plant in the mountains

    Scientists have found the origins of a mysterious, deadly flood in India

    A landslide of rock and ice caused the deadly flood that washed out two hydroelectric power plants in an Indian Himalayan state in February.

  12. hammerhead shark swimming in the ocean

    Something mysteriously wiped out about 90 percent of sharks 19 million years ago

    Deep sediments beneath the Pacific Ocean revealed a mystery: a massive shark die-off with no obvious cause.
