  1. A rendering of the Earth with a quarter section removed to show the inner workings of the core.
    Earth

    Earth’s inner core may be reversing its rotation

    In the past 13 years, the rotation of the planet’s solid inner core may have temporarily stopped and then started to reverse direction.

  2. A satellite view of an arctic cyclone taken in August 2012.
    Climate

    Cyclones in the Arctic are becoming more intense and frequent

    Over the last 70 years, boreal storms have steadily grown stronger. And climate change may make them worse, threatening both people and sea ice.

  3. A photo of China's maglev train as it comes into a station with several people standing at balcony of a nearby platform.
    Chemistry

    How rare earth elements’ hidden properties make modern technology possible

    Because of their unique chemistry, the rare earth elements can fine-tune light for many different purposes and generate powerful magnetic fields.

    Physics

    Rare ‘dark lightning’ might briefly touch passengers when flying

    Gamma-ray blasts from thunderstorms might occasionally zap passing airplanes, briefly exposing passengers to unsafe levels of radiation.

  5. A volcano erupts (blue) on Jupiter’s innermost moon, Io, in this picture from NASA’s Galileo spacecraft.
    Space

    Io may have an underworld magma ocean or a hot metal heart

    New calculations support dueling ideas for what powers the ubiquitous volcanoes on the hellish surface of Jupiter’s innermost moon.

  6. Enceladus, the moon of Saturn, shown partly illuminated against the backdrop of space
    Planetary Science

    The last vital ingredient for life has been discovered on Enceladus

    The underground ocean on Saturn’s icy moon may contain phosphorus in concentrations thousands of times greater than those found in Earth’s ocean.

  7. A photo of President Joe Biden signing the Inflation Reduction Act into law with a group of four men and one women standing around him.
    Climate

    2022’s biggest climate change bill pushes clean energy

    Experts weigh in on the pros and cons of the United States’ first major climate change legislation, the Inflation Reduction Act, signed this year.

  8. Physics

    50 years ago, physicists found the speed of light

    In the 1970s, scientists set a new maximum speed limit for light. Fifty years later, they continue putting light through its paces.

  9. A photo of a variety of zinc snowflake shapes crystallized in liquid gallium.
    Chemistry

    How to make tiny metal snowflakes

    In a pool of molten gallium, researchers grew symmetrical, hexagonal zinc nanostructures that resemble natural snowflakes.

  10. An illustration of a Natovenator polydontus sitting on top of a body of water with its feet visible below the water line
    Paleontology

    This dinosaur may have had a body like a duck’s

    Natovenator polydontus may have been adapted for life in the water, challenging the popular idea that all dinos were landlubbers.

  11. An underwater photo of a tiger shark with an orange camera on its side
    Ecosystems

    Tiger sharks helped discover the world’s largest seagrass prairie

    Instrument-equipped sharks went where divers couldn’t to survey the Bahama Banks seagrass ecosystem.

  12. An aerial photo of the Nioghalvfjerdsfjord glacier
    Climate

    Greenland’s frozen hinterlands are bleeding worse than we thought

    An inland swath of the Northeast Greenland Ice Stream is accelerating and thinning. It could contribute much more to sea level rise than estimated.
