  1. Animals

    DNA reveals donkeys were domesticated 7,000 years ago in East Africa

    When and where donkeys were domesticated has been a long-standing mystery. DNA now reveals they were tamed much earlier than horses.

  2. Space

    How balloons could one day detect quakes on Venus

    A new study opens the door for future balloon-based missions to study the geology of other worlds.

  3. Animals

    Whale sharks may be the world’s largest omnivores

    An analysis of the sharks’ skin shows that the animals eat and digest algae.

  4. Climate

    Vikings may have fled Greenland to escape rising seas

    Vikings abandoned Greenland in the 15th century. Lower temperatures, an expanding ice sheet and rising sea levels may have played a role in their departure.

  5. Life

    Fungi may be crucial to storing carbon in soil as the Earth warms

    Fungi help soil-making bacteria churn out carbon compounds that are resilient to heat, keeping those compounds in the ground, a study suggests.

  6. Space

    An ancient exploding comet may explain why glass litters part of Chile

    A 75-kilometer-long corridor of chunks of glass in the Atacama Desert probably formed when a comet exploded 12,000 years ago, a study finds.

  7. Earth

    Scientists are racing to save the Last Ice Area, an Arctic Noah’s Ark

    The Last Ice Area may be the final refuge for summer sea ice and the creatures that depend on it. Saving it is an ambitious goal with many hurdles.

  8. Earth

    Earth’s lower atmosphere is rising due to climate change

    In the Northern Hemisphere, the upper boundary of the troposphere, the slice of sky closest to the ground, rose 50 to 60 meters a decade from 1980 to 2020.

  9. Life

    Gene-edited stem cells help geckos regrow more perfect tails

    Regenerated gecko tails are a far cry from perfect. Now experiments have coaxed geckos to regrow better ones with nerve tissue and bonelike cartilage.

  10. Planetary Science

    What the Perseverance rover’s quiet landing reveals about meteor strikes on Mars

    InSight tried to detect seismic waves created by the arrival of its sister mission, helping scientists uncover how Mars absorbs energy from impacts.

  11. Archaeology

    Dog DNA reveals ancient trade network connecting the Arctic to the outside world

    People in Siberia were exchanging canines and probably other goods as early as 7,000 years ago with cultures as far off as Europe and the Near East.

  12. Astronomy

    China’s lunar rock samples show lava flowed on the moon 2 billion years ago

    The first lunar rocks returned to Earth in more than 40 years show that the moon was volcanically active later than scientists thought.
