    When it’s hot, plants become a surprisingly large source of air pollution

    During a heat wave, trees and shrubs can sharply raise ozone levels, a new study shows.

  7. HAT-P-26b illsutration
    Planetary Science

    Watery exoplanet’s skies suggest unexpected origin story

    Compared with Neptune, HAT-P-26b’s atmosphere has few heavy elements, suggesting it formed differently than the ice giants in Earth’s solar system.

    Paleontology

    ‘Baby Louie’ dinosaur identified as a new species

    A fossil embryo known as Baby Louie has been identified as a new species of dinosaur called Beibeilong sinensis.

  9. comet 67P
    Planetary Science

    Oxygen on comet 67P might not be ancient after all

    Molecular oxygen detected around comet 67P may not be a relic of the solar system’s birth. Instead, it may be generated by interactions of water, the solar wind and the comet’s surface.
