1. Ecosystems

    Warming pushes lobsters and other species to seek cooler homes

    Plants and animals are moving toward the poles, changing timing of important events and more — all in response to climate change.

  2. Environment

    Life on Earth is mostly green

    A new survey of life on Earth finds that plants and microbes dominate. But even though humans are in the minority, they still play a major role.

  3. Plants

    This houseplant can clean indoor air

    Houseplants may be able to help clean up polluted indoor air. Scientists gave this one a boost by givng it a gene from a rabbit.

  4. Plants

    Rare-plant hunters race against time to save at-risk species

    One in five plants is at risk of extinction. Meet the rare plant hunters who rappel down cliffs and trek through forests to save them.

  5. Plants

    Scientists Say: Nectar

    Nectar is a fluid filled with sugar that plants — especially flowers — produce. They use it to attract animals that will then spread their pollen to another plant.

  6. Plants

    Plants don’t grow well when always on high alert

    Plants make bitter-tasting chemicals to defend themselves against hungry bugs. But they pay a cost for always being on alert, scientists find.

  7. Plants

    The plant world has some true speed demons

    Some plants can fling, snap and hop at dizzying speeds. Such botanical gymnastics gives lie to the idea that all plants are slow, boring stick-in-the-muds.

  8. Plants

    Ouch! Lemons and other plants can cause a special sunburn

    These are among a host of plants (many found in the refrigerator vegetable drawer) that produce chemicals that will kill skin cells when activated by sunlight. The result can be a serious, localized sunburn — sometimes with blistering.

  9. Physics

    An ancient plant inspires a new lab tool

    Researchers have designed a lab tool that moves liquids from one place to another by mimicking a plant called a liverwort.

  10. Plants

    Scientists Say: Invasive species

    These are foreign species that are causing problems for native organisms and ecosystems.

  11. Climate

    Analyze This: Climate change could make food less healthy

    Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.

  12. Plants

    Venus flytraps tend not to eat their pollinators

    A first-ever study of what pollinates a Venus flytrap finds little overlap between the critters that serve as pollinators and those that are prey.
