Quantum technology is expected to transform our world, and Chicago appears to be at the center of this quantum acceleration, thanks to funding from the Department of Energy to establish two quantum research centers locally.

Monday's storm caused widespread damage, including in Chicago’s Lincoln Square, where a Weatherbug station recorded an 85 mph wind gust. (Patty Wetli / WTTW News)

The National Weather Service has confirmed that a tornado touched down in Rogers Park during Monday’s powerful storm. Thousands of Chicagoans remained without power Tuesday morning.
