Summit finds no easy solutions to Green Bay dead zone

Scientists were studying the factors that influence water quality in the bay, including oxygen levels. A longer-lasting dead zone is predicted in the bay this summer. MARK HOFFMAN

The tide of nutrients from tributaries will help create the latest, and most likely, longest-lasting dead zone in Green Bay this summer. Last week U.S. Rep.

U-M wants to recycle pee for use as food fertilizer


The University of Michigan wants to harvest your pee. The urine will be part of a research project to investigate whether disinfected urine samples could be safely recycled and used to fertilize crops for human consumption. The school is working with four other institutions in the first large-scale pilot project of its kind in the U.S.


Tapping into mine water for geothermal energy

Abandoned and choked with water, old mining tunnels are often viewed as a dangerous legacy. But the water in these mines could actually be a major geothermal resource. Michigan Technological University has created the first comprehensive guidebook communities can use to explore tapping into this resource.
