The Pawlenty administration and others watching the Minnesota economy see biotechnology as one bright light on the horizon. And no single place better captures Minnesota's biotech dreams than a sprawling, abandoned building on the western edge of St. Paul. The city bought the building this month to serve as a non-profit "incubator." Officials hope the empty space will nurture fledgling biotech entrepreneurs into tomorrow's powerhouse corporations.

Space exploration

The Columbia accident has renewed the debate over manned space flight, and whether it's worth the risk and expense to send astronauts rather than robots into space. Former astronaut Katherine Sullivan says manned space flights--and other types of exploration--should continue. Katherine Sullivan was a member of the very first space shuttle astronaut class.

Eighteen-year-old Jeffrey Parson begins this week confined to his parents' home in Hopkins, prevented from any contact with computers.
