ANN ARBOR, Mich. (AP) -- Hundreds of thousands of people are about to converge on Ann Arbor for the city's annual art fairs.
Four days' worth of art, music and food kick off Wednesday.
There actually are four different fairs: the Ann Arbor Street Art Fair, the Ann Arbor Summer Art Fair, the State Street Area Art Fair and the South University Art Fair.
One of the fairs' booths features art for sale that isn't just beautiful. It might also save lives.
It's called Bioartography. It features prints and notecards with scientific images taken through microscopes and scanners by University of Michigan Medical School scientists and their colleagues.
The proceeds of the sale help young scientists travel to conferences where they can share their work and make career connections.
