Lake sturgeon are amazing fish. They can weigh several hundred pounds and they can live to be 100 years old.

Sturgeon used to be abundant throughout the Great Lakes region. But they were overfished, and construction of dams on rivers where they spawn hurt their reproduction. They’re now a state threatened species.

Tim Cwalinski is a fisheries biologist with the Michigan Department of Natural Resources. He says these days, sturgeon are carefully managed.  There are a few fishing seasons for sturgeon in different parts of the state.

The season for sturgeon in Black Lake in Cheboygan County opens February 2nd. Tim Cwalinski says there are about 1,200 adult sturgeon in the lake.  The quota this year is just six fish total for all the fishermen combined.

ANN ARBOR, Mich. (AP) - Researchers affiliated with a new $28 million research center led by the University of Michigan will work to design the computers of 2025.

The Center for Future Architectures Research is opening Thursday. While the center is headquartered at Michigan, it includes researchers from top universities across the U.S.

C-FAR's goal is to harness the power and boost the reliability of the smallest transistors that'll emerge over the next decade. Transistors are the building blocks of modern electronics. More than a billion of them compose each integrated circuit in mobile phones and personal computers.
