  1. A photo of white opaque balloon with a wire and small contraption just below rising into a blue sky.

    50 years ago, a balloon circumnavigated the world for science

    A 1973 high-altitude flight kicked off an era of useful stratospheric balloon science. Some scientists worry that heightened concerns over alleged spy balloons might hamper that.

  2. A flooded street with stormy skies overhead

    By flying over atmospheric rivers, scientists aim to improve forecasts

    Drenching atmospheric rivers are slamming the U.S. West Coast, bringing needed water but dangerous flooding. Here’s how scientists study these storms.

  3. An illustration of Earth's center with lines running through it from on overlay map of North America.

    Earth’s inner core may be more complex than researchers thought

    Seismic waves suggest that Earth has a hidden heart, a distinct region within the solid part of the planet’s core.

  4. a huge column of smoke reaching into the stratosphere over Australia

    How wildfires deplete the Earth’s ozone layer

    Scientists detail the chain of chemical reactions that occur when wildfire smoke enters the stratosphere.

  5. A fossilized leaf of the extinct plant Gigantonoclea guizhouensis, with holes in pairs along the center

    Insect bites in plant fossils reveal leaves could fold shut millions of years ago

    The 252-million-year-old fossil leaves have symmetrical holes, which suggest an insect bit through the leaves when they were folded.

  6. A photo of a green backhoe parked next to a pile of rubble while search and rescue workers stand nearby.

    What to know about Turkey’s recent devastating earthquake

    Science News spoke with U.S. Geological Survey seismologist Susan Hough about the fatal February 6 earthquake near the Turkey-Syria border

  7. The Pantheon in Rome still stands including its soaring dome.

    These chemists cracked the code to long-lasting Roman concrete

    Roman concrete has stood the test of time, so scientists searched ruins to unlock the ancient recipe that could help architecture and climate change.

  8. An aerial view of Mountain Pass rare earth mine in southeastern California,

    Rare earth mining may be key to our renewable energy future. But at what cost?

    We take you inside Mountain Pass, the only rare earth mine in the United States.

  9. photo of cars backed up on a freeway with a sign above that reads, "EXTREME HEAT SAVE POWER 4-9PM STAY COOL"

    Extreme weather in 2022 showed the global impact of climate change

    Heat waves, floods, wildfires and drought around the world were exacerbated by Earth’s changing climate.

  10. An illustration of Shonisaurus popularis, ancient dolphinlike reptiles, swimming in water

    Mysterious ichthyosaur graveyard may have been a breeding ground

    Some 230 million years ago, massive dolphinlike reptiles gathered to breed in safe waters — just like many modern whales do, a study finds.

  11. The surface of Jupiter's moon Europa, showing cracks and ridges in the ice

    NASA’s Juno spacecraft’s mission has lasted longer than expected

    NASA’s Juno spacecraft continues to send back revealing new close-ups of Jupiter and its closest moons.

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

    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.
