Scientists team up to track fish

LANSING — Biologists and scientists have teamed up to track fish across the Great Lakes using sound—a literal Great Lakes echo.

It’s like the world’s biggest game of Marco Polo, but with fish.

The Great Lakes Acoustic Telemetry Observation Systems, or GLATOS, is a network of researchers sharing fish-tracking data from across the Great Lakes basin.

Acoustic telemetry tracks fish by surgically inserting a tracker into them before releasing them back into the water. As the fish travels, it emits an audible ping that can be picked up by markers placed in bodies of water across the region. Continue reading

UP scientists writes guide to fruit flies

LANSING — A common ancestor of fruit flies and humans emerged about 600 million years ago, long before the formation of the earth’s continents as we know them today.

Scientists discovered the link in the early 1900s, opening the floodgates to genetic research.

Fruit flies are cheap, grow rapidly and are easy to mutate. Their genetic likeness to humans allows researchers to study diseases like cancer, diabetes and immune resistance.

That makes them a model species for genetic research, said Thomas Werner, a professor of genetics and developmental biology at Michigan Technological University.

Werner recently co-authored a book “Drosophilids of the Midwest and Northeast,” which gives fruit flies overdue accolades. Continue reading

Seeking ‘Eureka!’ cries to solve environmental problems

LANSING — The state’s $1 million incentive for anyone who comes up with a new and innovative solution to prevent Asian carp from entering the Great Lakes.is part of a trend in using cash incentives to crowdsource and solve natural resource problems.

For instance, Michigan State University recently sponsored a challenge to redesign water foundations. The winning team won $15,000.

“The students are innovative and energetic and we were very excited to support student team learning and effort through problem solving,” said Professor Joan Rose, an MSU expert in water quality and public health safety.

Another example: The Michigan Design Council has sponsored contests for K-12 students to develop products to better enjoy the state’s water and winter. Continue reading

Invasive species gang up on native crayfish

LANSING — Invasive species in the Great Lakes are ganging up against native species.

A new study looking into invasive zebra and quagga mussels’ relationship with invasive rusty crayfish illustrates how the harm they cause together can be greater than either of them alone.

“What we found was that these invasive crayfish are really good at exploiting the resources provided by the (invasive) mussels,” said Mael Glon, who worked on this research while pursuing a master’s degree at Central Michigan University. “I don’t just mean eating them, because they are eating them, but they’re also eating what grows from what’s filtered from the mussels.”

The study was a collaboration between Central Michigan University (CMU) and Chicago’s Shedd Aquarium. It tested how the presence of the invasive mussels affected the growth and activity of both the invasive rusty crayfish and the native virile crayfish. The study funded by Michigan Sea Grant found that the mussels’ presence led to increased growth and activity of the invasive crayfish, but not the native ones. Continue reading

Detroit architect honored in new book

LANSING — Admirers of architect Wirt Rowland finally have the biography they were looking for. It was a long time coming.

Rowland was arguably the premier skyscraper architect of the early 20th century. He designed prominent buildings around the country for years. Yet his name is hardly known outside of architectural circles, and no one had bothered to write a book about the man.

That’s what struck Michael G. Smith of Bloomfield Hills and led him to write the just-released, “Designing Detroit: Wirt Rowland and the Rise of Modern American Architecture” (Wayne State University Press, $44.99).

The tome is comprehensive and meticulously detailed as Smith explores the rise of Rowland through the ranks of the architectural world and his work in Detroit. Despite his lack of training, Rowland earned a position in the city as an apprentice draftsman in 1901. Four years later, he was the lead designer for the two largest construction projects in Michigan. He went on to work for some of the most prominent architectural firms in the city, designing five of Detroit’s 16 prominent skyscrapers Continue reading
