  1. bryophyte

    Early land plants led to the rise of mud

    New research suggests early land plants called bryophytes, which include modern mosses, helped shape Earth’s surface by creating clay-rich river deposits.

  2. fishing map

    New mapping shows just how much fishing impacts the world’s seas

    Industrial fishing now occurs across 55 percent of the world’s ocean area while only 34 percent of Earth’s land area is used for agriculture or grazing.

  3. dino illustration

    New fossils are redefining what makes a dinosaur

    While some researchers question what characteristics define the dinosaurs, others are uprooting the dino family tree altogether.

  4. seal pup

    Strong winds send migrating seal pups on lengthier trips

    Prevailing winds can send northern fur seal pups on an epic journey.

  5. Gentoo penguin

    Look to penguins to track Antarctic changes

    Scientists say carbon and nitrogen isotopes found in penguin tissues can indicate shifts in the Antarctic environment.

  6. dwarf pines

    Ancient ozone holes may have sterilized forests 252 million years ago

    Swaths of barren forest may have led to Earth’s greatest mass extinction.

  7. algal bloom

    Humans are overloading the world’s freshwater bodies with phosphorus

    Human activities are driving phosphorus levels in the world’s lakes and other freshwater bodies to a critical point.

  8. agricultural fields

    Gassy farm soils are a shockingly large source of these air pollutants

    California’s farm soils produce a surprisingly large amount of smog-causing air pollutants.

  9. illustration of hellscape

    Life may have been possible in Earth’s earliest, most hellish eon

    Heat from asteroid bombardment during Earth’s earliest eon wasn’t too intense for life to exist on the planet, a new study suggests.

  10. ominous clouds

    Overlooked air pollution may be fueling more powerful storms

    The tiniest particles in air pollution aren’t just a health threat. They also strengthen thunderstorms, new research suggests.

  11. fracked well

    Volume of fracking fluid pumped underground tied to Canada quakes

    Study links volume of fracking fluid injected underground with hundreds of quakes in central Canada, and not the rate at which the fluids were injected.

  12. daphnia

    Rising CO2 in lakes could keep water fleas from raising their spiky defenses

    Rising CO2 in freshwaters may change how predators and prey interact in lakes.
