  1. three diamonds in varying shades of pink

    To form pink diamonds, build and destroy a supercontinent

    The Argyle deposit in Australia formed about 1.3 billion years ago, a study shows, along a rift zone that sundered the supercontinent Nuna.

  2. dinobird illustration

    This newfound birdlike dinosaur had surprisingly long legs

    Early birdlike dinosaurs are mostly short-limbed and thought to have lived in trees, but Fujianvenator prodigiosus may have run or waded in swamps.

  3. Two yellowish branches of a finger coral from the species Porites compressa are pictured.

    Adult corals have been safely frozen and revived for the first time

    Chunks of living corals could be frozen for safekeeping and revived later to restore reef ecosystems that are withering in warming seas.

  4. photo of large leaves from a tropical plant taken from below the forest canopy

    Some leaves in tropical forests may be getting too hot for photosynthesis

    Climate change may be forcing some tropical leaves to stop photosynthesis and die. It’s still unclear what effect this will have on entire forests.

  5. An illustration of the convergence of two black holes and yellow gravitational waves rippling through space.

    Recoiling black holes could move at nearly one-tenth the speed of light

    Knowing black holes’ speed after being kicked by gravitational waves can reveal how much energy converging black holes can release.

  6. A photo of a busy street with people walking around and cars on the road. Heat haze can be seen on the road.

    July 2023 nailed an unfortunate world record: hottest month ever recorded

    Roughly 6.5 billion people, or 4 out of 5 humans, felt the touch of climate change via hotter temperatures during July.

  7. A photo of a man facing away from the camera and pouring water out of a 2-liter jug onto his head.

    Here’s how much climate change increases the odds of brutally hot summers

    Climate change made 2023’s record-breaking heat waves in the United States, Mexico, China and southern Europe much more likely, new simulations show.

  8. A photo of a temperature board in Phoenix, Arizona showing 110 degrees and the time 1:22 p.m.

    What’s causing this summer’s extreme heat waves?

    Climate change and meandering jet streams are fomenting this summer’s extreme waves of heat.

  9. A digitally illustrated image of the Earth in a frying pan hovering over an open set of flames.

    Last week was the hottest ever recorded — here’s why we keep smashing records

    Global temperature records are being shattered as El Niño and climate change combine to push the Earth into uncharted territory, researchers say.

  10. An illustration of an Anomalocaris canadensis underwater.

    This ancient, Lovecraftian apex predator chased and pierced soft prey

    Half a billion years ago, Anomalocaris canadensis probably used its bizarre headgear to reach out and snag soft prey with its spiky clutches.

  11. A drone photo of a southern stretch of the North American boreal forest burnt by wildfires.

    The snow forest of North America may be about to shrink

    From 2000 to 2019, the boreal forest’s northern boundary didn’t move while southern tree cover thinned due to climate change, wildfires and logging.

  12. A photo of a dusty barren ground with the tree line seen in the middle distance.

    The Amazon might not have a ‘tipping point.’ But it’s still in trouble

    Scientists race to foretell the fate of the vast forest facing deforestation and climate change.
