n the basement of an octagon-shaped building that squats amid woods on Milwaukee’s northwest side, 16 wires send low-level electric currents through a small glass tank filled with water, across which a device called a trolley shuttles to and fro. Aboard is a simulated woman’s breast with a tumor. From this research project, which outgrew its lab at the University of Wisconsin-Milwaukee, will emerge a surer way of detecting breast cancer – if all goes well. Success also would demonstrate the community payoff of academic research, which Chancellor Carlos Santiago wants to step up at UWM.
