1. glitter

    This eco-friendly glitter gets its color from plants, not plastic

    Using cellulose extracted from wood pulp, researchers have created a greener alternative to traditional glitter.

  2. barren landscape with chunks that look like rocks

    An ancient exploding comet may explain why glass litters part of Chile

    A 75-kilometer-long corridor of chunks of glass in the Atacama Desert probably formed when a comet exploded 12,000 years ago, a study finds.

  3. A landscape shot of the Last Ice Area, with the sun setting or rising over ice

    Scientists are racing to save the Last Ice Area, an Arctic Noah’s Ark

    The Last Ice Area may be the final refuge for summer sea ice and the creatures that depend on it. Saving it is an ambitious goal with many hurdles.

    Climate change may be shrinking tropical birds

    Scientists had previously found that migratory birds are getting smaller as temperatures rise. Dozens of tropical, nonmigratory species are too.

  5. a slice of diamond with tiny gray blobs of a newfound mineral called davemaoite

    A mineral found in a diamond’s flaws contains the source of some of Earth’s heat

    A mineral theorized to exist in the mantle was found hiding in a diamond. Dubbed davemaoite, it could explain where some of Earth’s heat comes from.

  6. image of Earth's atmosphere with the troposphere visible in orange

    Earth’s lower atmosphere is rising due to climate change

    In the Northern Hemisphere, the upper boundary of the troposphere, the slice of sky closest to the ground, rose 50 to 60 meters a decade from 1980 to 2020.

  7. image of a flaming gas flare at an oil field in Texas

    Earth will warm 2.7 degrees Celsius based on current pledges to cut emissions

    The world still lags on its commitments to lower greenhouse gas emissions and forestall the worst effects of global warming, a new U.N. report shows.

  8. columns of ice mixed in with pebbles and dirt

    Here’s how ice needles sculpt patterns into cold, rocky landscapes

    Striking stone patterns decorate remote, frigid landscapes. The recipe for these naturally forming stripes and swirls: Freeze, thaw, repeat.

  9. Fish swimming around roots of red mangrove forest

    How these sea-loving mangroves ended up far from the coast

    On the Yucatán Peninsula, mangroves trapped nearly 200 kilometers from the ocean are part of a “relict ecosystem” that’s more than 100,000 years old.

  10. image of earthshine

    Earth is reflecting less light. It’s not clear if that’s a trend

    A decrease in Earth’s reflectance shows our planet is absorbing more solar radiation, but it’s not clear if the trend will last.

    Science & Society

    How our SN 10 scientists have responded to tumultuous times

    COVID-19, social justice movements and the realities of climate change have given our Scientists to Watch new perspective.

  12. visualization of ocean surface currents in the oceans around the Americas

    Work on complex systems, including Earth’s climate, wins the physics Nobel Prize

    Syukuro Manabe and Klaus Hasselmann pioneered work on computer simulations of Earth’s climate. Giorgio Parisi found hidden patterns in disordered complex materials.
