1. Climate

    It’s possible to reach net-zero carbon emissions. Here’s how

    Cutting carbon dioxide emissions to curb climate change and reach net zero is possible but not easy.

  2. Environment

    Recycling rare earth elements is hard. Science is trying to make it easier

    As demand grows, scientists are inventing new — and greener — ways to recycle rare earth elements.

  3. Environment

    Rare earth elements could be pulled from coal waste

    The scheme would provide valuable rare earth metals and help clean up coal mining’s dirty legacy.

  4. Climate

    Cyclones in the Arctic are becoming more intense and frequent

    Over the last 70 years, boreal storms have steadily grown stronger. And climate change may make them worse, threatening both people and sea ice.

  5. Earth

    Rare earth mining may be key to our renewable energy future. But at what cost?

    We take you inside Mountain Pass, the only rare earth mine in the United States.

  6. Climate

    2022’s biggest climate change bill pushes clean energy

    Experts weigh in on the pros and cons of the United States’ first major climate change legislation, the Inflation Reduction Act, signed this year.

  7. Animals

    Dry pet food may be more environmentally friendly than wet food

    The environmental cost of wet pet food is higher than dry food, scientists say. That may be because wet food gets most of its calories from animals.

  8. Health & Medicine

    Pollution mucks up the lungs’ immune defenses over time

    A study of immune tissue in the lungs reports that particulate matter buildup from air pollution may impair respiratory immunity in older adults.

  9. Animals

    These devices use an electric field to scare sharks from fishing hooks

    SharkGuard gadgets work by harnessing sharks’ ability to detect electric fields. That could save the animals’ lives, a study suggests.

  10. Climate

    Wind turbines could help capture carbon dioxide while providing power

    Turbulent wakes from wind turbines can concentrate CO2 from cities and factories, making it easier to remove the greenhouse gas from the atmosphere.

  11. Earth

    Landslides shaped a hidden landscape within Yellowstone

    Scientists have used lasers to get a detailed view of the national park’s topography, and they’ve spotted more than a thousand landslides.

  12. Environment

    Heat waves in U.S. rivers are on the rise. Here’s why that’s a problem

    In recent years, heat waves in U.S. rivers have gotten more frequent, causing trouble for fish, plants and water quality.
