  • Teens use science to worm through plastic waste

    PHOENIX, Ariz. — Four teens set out to study what turns mealworms into plastic eating powerhouses. The right worm could munch through a plastic mountain, they found. But all worms aren’t the right ones. Another surprise: Bigger isn’t always better.

    The high-school students showed off their results here, last month, at the Intel International Science and Engineering Fair. Created by...

  • Catching ‘Dory’ fish can poison entire coral reef ecosystems

    The popularity of animated kids’ movies — Finding Nemo and its new sequel, Finding Dory — could spell doom for many coral reef communities, a new study warns. But even without families trying to bring home the types of fish portrayed in these films, coral-reef species are in trouble. The aquarium industry has been harvesting fish as pets. And more than half of the saltwater fish sold as U.S....

  • Fighting big farm pollution with a tiny plant

    PHOENIX, Ariz. — Sometimes a tap water ban can prove a scientific wakeup call.

    When Toledo, Ohio told its residents not to drink tap water in 2014, Julia Hunckler, 17, took notice. This Marian High School junior lived across the state line in Mishawaka, Ind. The Ohio ban was due to toxins in Lake Erie. A summer bloom of algae had tainted the lake, which was used as a source of drinking...

  • Concrete science

    PHOENIX, Ariz. — Concrete is the most common artificial material on the planet. It’s used to make roads, bridges and dams. It anchors fence posts and makes durable outdoor stairs. Chances are, concrete forms the foundation of the building you live in. Humans use billions of tons of it each year. That’s enough for each man, woman and child on Earth to have their own personal concrete cube...

  • “Couch potatoes” tend to be TV-energy hogs

    Television brings us lots of news and entertainment. It also eats up electricity. A new analysis now offers a bright idea for lowering the electricity used by TV viewers: Focus on the couch potatoes.

    Energy-efficiency programs reward people for doing things to use less electricity. For example, new TV sets tend to use far less electricity than older ones. So an energy-efficiency program...

  • How ancient African fish feed today’s Amazon

    The second of two parts on the impacts of intercontinental plumes of dust. Find part 1 here.

    It begins with a darkening sky, then a distant roar. Leaves rustle as monkeys scamper through the trees above. Drops of their pee sprinkle down through the leaves. Then they start to howl. It is more like a deafening yowl. Unseen in the trees overhead, a chorus of howler monkeys scream at the...

  • Microbes mine treasure from waste

    Moldy food, dirty toilet water and bags of garbage. What do these disgusting things have in common? Tiny, one-celled microbes called bacteria love them. These germs are too small to see with your eyes, but they live all around you. Bacteria set up camp in sewage pipes, ponds and dirt. They also live in your house, on your food, in your mouth and in your gut. Some of these germs make you sick....

  • A shock to the food system

    WASHINGTON, D.C. — Feeding the world’s population is a big challenge, and it’s about to get bigger. Right now, a little more than 7.3 billion people share the planet. Most nights, many go to bed hungry. By 2050, some scientists estimate, the world’s population may reach 9 billion. Earth’s changing climate will probably make feeding this far greater number a very daunting task. That was the...

  • Powered by poop and pee?


    Every day, people visit the toilet. Or, in developing nations, the field, pit or other location where they can relieve themselves. With more than 7 billion people on the planet, that’s a lot of waste. Mixed with water, these wastes are known as sewage. Because they host germs, they can’t just be left lying around. If they taint the water people use for eating, drinking and bathing...

  • Paris meeting yields climate agreement

    On December 12, delegates to the United Nations climate change meeting outside Paris, France, came to a final agreement. They agreed to curb the worst effects of climate change by limiting global warming to “well below” 2° Celsius (3.4 °Fahrenheit). Representatives of 195 countries agreed to the blueprint for action.

    For perspective, last year, the average temperature across all land and...
