    Dim lighting may raise the risk of a West Nile virus exposure

    Dimly lit nights increased risk of West Nile virus exposure in chickens. Artificial light proved a better predictor of risk than population or paving.

    A year after Australia’s wildfires, extinction threatens hundreds of species

    As experts piece together a fuller picture of the scale of damage to wildlife, more than 500 species may need to be listed as endangered.

    Modified genes can distort wild cotton’s interactions with insects

    In a Yucatan nature park, engineered genes influence nectar production, affecting ants’ and maybe pollinators’ attraction to the wild cotton plants.

    Animals

    50 years ago, scientists made the case for a landlubbing Brontosaurus

    In 1971, a scientist argued for a landbound Brontosaurus instead of a swampy swimmer. Recent evidence comes from studies of its ancient environment.

    Ocean acidification may make some species glow brighter

    Ocean organisms use bioluminescence for hunting, defense and more. A new analysis shows that declines in water pH might change who glows and how much.

    Clearing land to feed a growing human population will threaten thousands of species

    Changing where, how and what food is grown could largely avoid biodiversity losses, scientists say.

    Plastic waste forms huge, deadly masses in camel guts

    Eating plastic isn’t just a sea animal problem. Researchers found suitcase-sized masses of plastic in dromedaries’ guts in the United Arab Emirates.

    Plastics are showing up in the world’s most remote places, including Mount Everest

    From the snow on Mount Everest to the guts of critters in the Mariana Trench, tiny fragments called microplastics are almost everywhere.

    A new map shows where Asian giant hornets could thrive in the U.S.

    Suitable habitat along the Pacific West Coast means so-called “murder hornets” could get a foothold in North America if they aren’t eradicated.
