Earth and Human Activity

  1. Animals

    Electronics may confuse a bird’s ‘compass’

    Birds use Earth’s magnetic field to help guide them as they migrate. A new study suggests that electromagnetic radiation given off by some electronic devices may act like “noise” and confuse the long-traveling birds.

  2. Tech

    The road less worn

    Two teens have found a new use for old tires. By grinding them up and adding them to asphalt, the old rubber can create stronger, longer-lived roads. And the bonus: The process recycles tires that might otherwise have been burned, creating pollution.

  3. Climate

    Arctic sends weird weather south

    Arctic warming is affecting weather farther south, where most of the world lives. The impacts are especially worrisome for agriculture.

    Intel STS finalist takes on arsenic poisoning

    Concerned about arsenic poisoning in Bangladesh, Intel Science Talent Search finalist Thabit Pulak invented an affordable filter to help people remove this toxic pollutant from their drinking water.

  5. Environment

    China exports pollution alongside goods

    Many companies have moved the plants that make their products to developing countries, such as China. But the pollution linked to making those products can travel around the world.

  6. Animals

    Birds versus windows

    Buildings in the United States can be deadly obstacles to flying birds. A new study estimates that as many as 1 billion birds die every year after colliding with windows. And low buildings — not skyscrapers — account for most of those deaths.

  7. Earth

    Mining metals amidst seafloor animals

    Miners may need to get their feet — and everything else — wet as they carefully seek out loads of copper and other valuable natural resources.

  8. Microbes

    Arctic thaw is spreading wildlife diseases

    Polar animals are encountering new, killer parasites as melting ice unlocks their access to new hosts.

  9. Animals

    First living fish leaves ‘endangered’ list

    Twenty-one years ago, a minnow facing a high risk of extinction was placed on the U.S. Endangered Species List. With help from scientists, the fish appears to have largely recovered. It’s the first ‘listed’ fish to do so.

  10. Life

    Caught in the act

    Scientists observe some evolutionary speed demons as they adapt over the course of just a few years to new environmental conditions.

    Explainer: People can sicken animals

    Wildlife can sometimes become infected with germs shed by people.

    Explainer: Ocean acidification

    Here’s why shellfish and other animals in the sea suffer when the ocean is forced to absorb too much carbon dioxide.
