All Stories by Sid Perkins

  1. Earth

    A rapid rise for the Andes

    New evidence suggests that the South American mountain chain shot up 2.5 kilometers in a geological blink of an eye.

  2. Earth

    Tunguska, a century later

    Asteroid or comet blamed for Siberian blast of 1908

  3. Earth

    Slip, Slide, Shake

    Analyses of GPS and seismic data about one of Antarctica’s largest and most dynamic glaciers provide new insights into the ice stream’s lurching march to the sea.

  4. Earth

    Lucky Shot

    Satellite catches pyroclastic flow in motion.

  5. Earth

    Natural heat

    Heat from the decay of radioactive elements deep within the planet could meet Earth’s energy needs almost three times over — if we could harness all of it.

  6. Earth

    Virtual seismometer

    A new supercomputer simulation of the large quake that struck central China earlier this month could help researchers estimate the size of the ground motions experienced in areas that didn’t have seismic instruments.

  7. Earth

    Death downwind

    Pollutants generated by human activity in Europe significantly boost ozone concentrations downwind, harming people’s health and causing thousands of premature deaths in North Africa, the Near East and the Middle East.

  8. Archaeology

    Footprints in the ash

    Humans may have been walking around what is now central Mexico 40,000 years ago.

  9. Life

    Killer bee colonization

    A NASA project will combine satellite observations of plant growth in the continental United States and projections of how climate might change in coming years to estimate where “killer bees” could ultimately survive in the wild.

  10. Earth

    Life down deep

    Deep-sea sediments provide a habitat for diverse and abundant populations of microorganisms and may be home to as much as 70 percent of the bacteria on the planet, new studies suggest.

  11. Paleontology

    Walking tall

    Some types of the largest flying reptiles ever known were well adapted to life on the ground.

  12. Ecosystems

    That sinking feeling

    The sea level rise expected in the coming century will swamp the Everglades unless current management is adjusted or climate change is curbed.
