  1. illustration of Tupandactylus imperator

    Pterosaurs may have had brightly colored feathers on their heads

    The fossil skull of a flying reptile hints that feathers originated about 100 million years earlier than scientists thought.

  2. a fossil spider, with an inset showing the fossil in ultraviolet light that revealed a substance possibly produced by diatoms

    Glowing spider fossils may exist thanks to tiny algae’s goo 

    Analyzing 22-million-year-old spider fossils from France revealed that they were covered in a tarry black substance that fluoresces.

  3. photo of several people standing on an overturned vehicle covered in debris amid floodwaters

    Climate change intensified deadly storms in Africa in early 2022

    Tropical storms battered southeast Africa in quick succession from January through March, leading to hundreds of deaths and widespread damage.

  4. aerial photo of floating solar panels on a lake in Haltern, Germany

    A UN report says stopping climate change is possible but action is needed now

    We already have a broad array of tools to reduce global greenhouse gas emissions in half by 2030, a new report finds. Now we just have to use them.

  5. Arctocyon primaevus skull

    Mammals’ bodies outpaced their brains right after the dinosaurs died

    Fossils show that mammals’ brains and bodies did not balloon together. The animals’ brains grew bigger later.

  6. illustration of Spinosaurus, a dinosaur with a large fin, hunting fish

    Spinosaurus’ dense bones fuel debate over whether some dinosaurs could swim

    New evidence that Spinosaurus and its kin hunted underwater won't be the last word on whether some dinosaurs were swimmers.

  7. photo of a police car in the foreground with cloud of smoke billowing above Yanderra township buildings

    Smoke from Australia’s intense fires in 2019 and 2020 damaged the ozone layer

    Massive fires like those that raged in Australia in 2019–2020 can eat away at Earth’s protective ozone layer, researchers find.

  8. map of light pollution in the North Sea

    Even the sea has light pollution. These new maps show its extent

    Coastal cities and offshore development create enough light to potentially alter behavior of tiny organisms dozens of meters below the surface.

  9. pebbles in the foreground with Greenland's ice sheet in the background

    The mysterious Hiawatha crater in Greenland is 58 million years old

    An impact crater spotted in 2015 in Greenland is far too old to be connected to the Younger Dryas cold snap from 13,000 years ago, a study suggests.

  10. illustration of a giant crocodile eating a dinosaur

    Fossils show a crocodile ancestor dined on a young dinosaur

    The 100-million-year-old fossil of a crocodile ancestor contains the first indisputable evidence that dinosaurs were on the menu.

  11. aerial photo of a U.S. Coast Guard boat collecting spilled oil from Deepwater Horizon

    Sunlight helps clean up oil spills in the ocean more than previously thought

    Solar radiation dissolved as much as 17 percent of the surface oil slick spilled after the 2010 Deepwater Horizon explosion, a new study suggests.

  12. images of adult and juvenile pterosaur fossils with arrows pointing to fossilized gastric pellets

    Fossils reveal that pterosaurs puked pellets

    Fish scale–filled pellets found by two pterosaurs are the first fossil evidence the flying reptiles regurgitated undigestible food, like some modern birds.
