1. Earliest recorded ‘ice-out’ date on Douglas Lake at U-M Biological Station

    The ice-out, declared on March 16 this year, comes after the latest-recorded Douglas Lake “ice-in” occurred on Jan. 6 — making this the shortest season of lake ice cover recorded at the BioStation in Northern Michigan: just 70 days.

  2. Could riding older school buses hinder student performance?

    Students who ride newer, cleaner-air buses to school have improved academic performance, according to a U-M study that linked school bus funding information with standardized test scores and found improvements in reading/language arts and math scores when the oldest buses were replaced with newer vehicles.

  3. Legacy in land: Protecting rare fens, century farms, and other natural habitats in Michigan

    Prairie fens, which take thousands of years to develop, exist predominantly in southern lower Michigan and occur where cold, alkaline groundwater bubbles to the surface. The springs feed rivers and lakes with clean water. At the LaCroix Legacy Land Conservancy, alumna Susan Morley is dedicated to the voluntary conservation of locally important land.

  4. U-M Biological Station activates snowpack sensor to study changing winters

    Increasingly common rain-on-snow weather events are reducing snowpack and washing away nutrients from soils to our streams and lakes. This winter, snow science researchers at U-M’s Biological Station are tracking the snowpack at an hourly rate to get a deeper understanding of the complexities of global environmental change.

  5. Food from urban agriculture has surprisingly high carbon footprint

    A new U-M-led international study finds that fruits and vegetables grown in urban farms and gardens have a carbon footprint that is, on average, six times greater than conventionally grown produce. However, a few city-grown crops equaled or outperformed conventional agriculture under certain conditions.

  6. Art or infrastructure? Depends on the climate

    ‘Migration Stage,’ an outdoor installation along Seattle’s Elliot Bay, serves a once-and-future purpose, says artist Buster Simpson, MFA ’69. Its movable ‘kit of parts’ provides a unique place to gather, while it functions as ‘sea armor’ to protect shoreline infrastructure against extreme storms. (Image credit: Joe Freeman Jr.)

  7. Kris Sarri: Combating climate change with a policy pen

    A thriving environment depends on engaging people in its stewardship, says Kris Sarri, MPH ’97. She has spent two decades in Washington, D.C., where her commitment to public health weaves together environmental protection and community development.

  8. Space weather disrupts nocturnal bird migration, study finds

    Birds and other animals rely on Earth’s magnetic field for long-distance navigation during seasonal migrations. U-M researchers are now learning how periodic disruptions of the planet’s magnetic field, caused by solar flares and other energetic outbursts, affect the reliability of those biological navigation systems.

  9. Water conservation and access will be yearlong focus at UMSI

    School of Information students are looking through the ‘lens of an information professional’ and using data to tackle urgent water-related issues in Michigan and around the globe. Partners in the school’s inaugural ‘theme year’ include representatives from the National Oceanic and Atmospheric Administration.
