  • Reading magma, predicting giant eruptions
    Reading magma, predicting giant eruptions

    Volcanic eruptions are unpredictable, but here’s a new view of the historic eruption of a Mediterranean monster. About 3,500 years ago, Santorini’s eruption left a giant caldera and 60-meter layers of pumice. A new study of tiny crystals tracks the movement of molten magma before the cataclysm.

  • Ocean fish in hot water
    Ocean fish in hot water

    The ocean’s most valuable fish are caught in a vise. Areas known as dead zones are encroaching on their living zones and pinning them closer to the surface, where they are more vulnerable to becoming the day’s catch. The predicament is yet another side effect of climate change.

    Science on the road!

    Hitting the road? What could be more enlightening than gawking at a cave, exploring a desert, or eyeballing the largest telescope in the world? Need proof that science is not just books and websites or equations and software? Get moving!

  • Tornado prediction
    Tornado prediction

    Tornadoes need wet air, dry air, and wind shear. What explains the big improvement in tornado prediction? Is climate change boosting these storms?

  • Tsunami: The killer wave
    Tsunami: The killer wave

    After earthquakes caused horrific tsunamis in Sumatra and Japan, we wonder where tsunamis get their power, how warning systems work, and what’s left after the cataclysm.

  • Climate: Simple = beautiful?
    Climate: Simple = beautiful?

    Earth’s orbit subtly changes over thousands of years, in complex cycles that affect the timing and delivery of sunlight to various regions of the globe. Climatologists have said that when this “Milankovitch cycle” warms the Arctic, it somehow warms the Antarctic. A new study finds that the cycle acts more directly.

  • State of the rivers: Ruinous?
    State of the rivers: Ruinous?

    Rivers bring water. They house amazing biodiversity. And they are being polluted, tapped, dammed and diverted at a frightening rate. What does a new study of global rivers tell us about something we can’t afford to lose?

  • When earthquakes break…
    When earthquakes break…

    How do rocks move? What governs how long and violent an earthquake will be? Should we worry about a powder between the grinding rocks? Why do a few earthquakes grow into monsters?

  • Energy and climate: The hidden stories
    Energy and climate: The hidden stories

    Climate scientists worry about feedbacks, glacial melting, sea level rise, using tax policy to slow warming, and the complexity of climate science. Is it realistic to base our economy on endless growth? What does human behavior tell us about dealing with warming?
