  1. A photo from a high angle of the Grand Prismatic Hot Spring
    Earth

    No, Yellowstone isn’t about to erupt, even after more magma was found

    A new study offers the best views yet of what lurks beneath the Yellowstone supervolcano.

  2. A photo of the eruption of Hunga Tonga-Hunga Ha’apai volcano.
    Earth

    The Hunga Tonga volcano eruption touched space and spawned a lightning blitz

    The eruption of the Hunga Tonga-Hunga Ha’apai volcano in the Pacific Ocean earlier this year was one for the record books — in several surprising ways.

  3. A blonde woman points at a tooth on T. rex skull dubbed Maximus
    Paleontology

    Why the sale of a T. rex fossil could be a big loss for science

    At least half of the roughly 120 known T. rex fossils are owned privately and not available to the public. “Maximus” may join them.

  4. Lava spewing from a fissure with smoke rising
    Earth

    Hawaii’s Mauna Loa volcano is erupting. Here’s what you need to know

    A geophysicist with the U.S. Geological Survey answers questions about the recent eruption of the world's largest active volcano.

  5. Iceberg A68a in the Southern Ocean during July 2020
    Climate

    Here’s what happened to the Delaware-sized iceberg that broke off Antarctica

    The powerful pull of currents in the Southern Ocean probably pulled apart the largest remnant of a massive iceberg that split off Antarctica in 2017.

  6. illustration of two Scleromochlus taylori reptiles surrounded by fern leaves
    Paleontology

    Pterosaurs may have evolved from tiny, fast-running reptiles

    A mysterious little ground-dwelling reptile unearthed in a Scottish sandstone over 100 years ago turns out to be part of a famous flying family.

  7. illustration of brown and tan Xiushanosteus mirabilis fish underwater
    Paleontology

    Ancient fish fossils highlight the strangeness of our vertebrate ancestors

    New fossils are revealing the earliest jawed vertebrates — a group that encompasses 99 percent of all living vertebrates on Earth, including humans.

  8. photo of Mount Nyiragongo erupting
    Earth

    In 2021, a deadly volcano erupted with no warning. Here’s why

    Before the Nyiragongo eruption, underground magma was already close to the surface and so didn’t trigger instruments that look for lava movement.

  9. Buildings with mountains in the background in Nuuk, Greenland
    Earth

    The Arctic is warming even faster than scientists realized

    The Arctic isn’t just heating up two to three times as quickly as the rest of the planet. New analyses show that warming is almost four times as fast.

  10. a man in a red shirt and a black cap standing in front of a misting fan
    Climate

    Humans may not be able to handle as much heat as scientists thought

    Humans’ capacity to endure heat stress may be lower than previously thought — bad news as climate change leads to more heat waves around the globe.

  11. an illustration of a mammal ancestor, with a rodent-like head and long furry body, exhaling hot air on a cold night
    Paleontology

    Mammal ancestors’ shrinking inner ears may reveal when warm-bloodedness arose

    An abrupt shift in inner ear shape of mammal ancestors 233 million years ago, during a time of climate swings, points to evolution of warm-bloodedness.

  12. An illustration of Meraxes gigas, a large dinosaur with a big head, fearsome teeth and tiny arms similar to a T. rex, roaring, with other dinosaurs in the background
    Paleontology

    A newfound dinosaur had tiny arms before T. rex made them cool

    A predecessor to Tyrannosaurus rex, Meraxes gigas had a giant head and puny but muscular arms, suggesting the limbs served some purpose.
