  1. Earth

    Naked planet

    Scientists officially launch OneGeology, a project that will produce a single digital map of the planet’s geological formations.

  2. Life

    Time to chill

    Well-preserved fossils deposited in an Antarctic lake about 14 million years ago pin down when a large part of the now-icy continent most recently dipped below freezing.

  3. Paleontology

    Soft tissue in fossils still mysterious

    New research suggests modern biofilms could contaminate ancient fossils.

  4. Earth

    Seafloor chronicles

    Survey of ocean floor reveals long history, from a geological fault to the wreckage of the Lusitania.

  5. Oceans

    Death by magma

    Widespread extinctions in the world’s oceans millions of years ago may have been triggered by massive underwater volcanic eruptions that created much of the Caribbean seafloor.

  6. Climate

    Another climate ailment

    Global warming may turn out to be more than just a pain in the neck: Rising average temperatures could trigger an increased prevalence of kidney stones.

  7. Earth

    Howdy, neighbor!

    About 800 million years ago, East Antarctica, now one of the coldest regions on Earth, abutted what is now Death Valley, Calif., one of the hottest.

  8. Earth

    Precious little gems

    Ancient microdiamonds embedded inside ancient zircons found in western Australia suggest that life may have existed on Earth up to 4.25 billion years ago.

  9. Physics

    Layers in a Stradivarius

    Slight differences in the wood from which violins are made might be what distinguishes a mellow-toned Stradivarius from an ordinary instrument.

  10. Earth

    Under Ice

    Cruising in an icebreaker to the top of the world, scientists identified the aftermath of an event once thought impossible: a violent volcanic eruption on the deep-sea floor.

  11. Life

    Fossil helps document shift from sea to land

    New fossils of an ancient, four-limbed creature help fill in the blanks of the evolutionary transition between fish and the first land-adapted vertebrates.

  12. Earth

    Unintended consequences

    A full recovery of the ozone hole over Antarctica in the coming years could significantly boost warming of the atmosphere over and around the icy continent.
