Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

  1. Ecosystems

    Underwater meadows appear to fight ocean germs

    The seagrasses that sway in coastal currents are more than aquatic groundcover. They can reduce harmful bacteria that might otherwise sicken neighboring animals, new data show.

  2. Environment

    Food-like smell on plastic may lure seabirds to eat it

    When plastic smells like supper, seabirds and other animals can be fooled into thinking it is food.

  3. Climate

    Predicting a wildfire with data from space

    When the West gets dry it can catch fire. A teen decided to find out if satellite data might show where a fire’s fuel might reside.

  4. Environment

    Ocean of the future may make shrimp small and colorful

    Carbon dioxide released into the air can end up in the ocean, making it more acidic. A teen showed that this acidification could shrink shrimp and make them more colorful.

  5. Animals

    Spidey sense: They can hear you!

    Surprise! At least some spiders can hear us. Even without eardrums, jumping spiders can still detect airborne sounds from across the room.

  6. Oceans

    Beaches can be a germy playground

    Infectious microbes can flourish on sandy beaches. Scientists are now exploring how to find and monitor these hotspots for pollution that can make vacationers sick.

  7. Oceans

    Creative ways to help coral reefs recover

    Coral reefs are under siege from threats ranging from climate change to explosives. But scientists are developing ways to rebuild reefs before they disappear.

  8. Environment

    Laundering clothes may send indoor pollutants outdoors

    Clothing absorbs pollutants from indoor air. During washing and drying, the fabric releases those chemicals into the outdoor environment, a new study finds.

  9. Health & Medicine

    U.S. to outlaw antibacterial soaps

    Soaps with germ-killing compounds promise cleaner hands. But manufacturers couldn’t show they offer any safety advantage. Now the U.S. government is banning them.

    Cool Jobs: Linking animal health to human health

    Scientists who watch out for diseases in wild animals also can play a role in keeping people from getting sick.
