1. Acid rain threatens Great Lakes sugar maples

    Because they grow in calcium-rich soils, sugar maple forests in the Great Lakes region have largely been spared the damage caused by acid rain in the Northeast. But now, U-M ecologists has uncovered a different and previously unstudied mechanism by which acid rain harms sugar maple seedlings in Upper Great Lakes forests.

  2. 150 rivers in a lab

    More than 3,000 gallons of Huron River water were trucked to the U-M campus recently to create 150 mini-Hurons that are used to study how environmental changes affect freshwater habitats like rivers and streams.

  3. ‘Fingerprinting’ method tracks mercury emissions from coal-fired power plant

    For the first time, the chemical “fingerprints” of the element mercury can directly link environmental pollution to a specific coal-burning power plant. “We see a specific, distinct signature to the mercury that’s downwind of the power plant, and we can clearly conclude that mercury from that power plant is being deposited locally,” said U-M researcher Joel Blum.

  4. Careless disposal of antibiotics can create aquatic superbugs

    A wastewater treatment plant can provide the perfect mating ground for carelessly disposed of antibiotics to form superbugs that are eventually discharged into streams and lakes, says U-M researcher Chuanwu Xi.

  5. Back to basics in the kitchen and garden

    Seems more people are interested in eating fresh, healthy foods. An alumnus and his co-author wife, who have built their own “farmstead” offer tips to get you started on the healthy, do-a-little-bit-more-yourself lifestyle.

  6. Researchers predict record Gulf of Mexico 'dead zone' due to Mississippi River flooding

    Extreme flooding of the Mississippi River this spring is expected to result in the largest Gulf of Mexico “dead zone” on record, according to a University of Michigan aquatic ecologist and his colleagues.

  7. Great big trouble for the Great Lakes

    Already under stress by invasive species and pollution, the Great Lakes are now seeing the reappearance of a problem once believed solved: dead zones, where no life survives. Worse yet, climate projections indicate that the problem is likely to grow.

  8. America's heart

    When alumnus Bill Sparrow decided to kayak the entire length of the Mississippi River, he and his wife Laura expected adventure. But they didn’t expect a whole new understanding of their country, its grandeur and its people.

  9. What's going on with the weather?

    U-M weather expert professor Perry Samson responds to questions about extreme weather, including hurricanes, tornadoes and thunderstorms.
