In the wake of the Grateful Dead's final shows, we reflect on the weekend with a music industry professional and a dedicated Deadhead.

When it comes to treating our sewage, Chicago has a history of thinking big from reversing the flow of the Chicago River to the creation of Deep Tunnel. Jay Shefsky visited the Thornton Quarry and went to the bottom of Deep Tunnel to see where the water will flow into the new reservoir later this year. We revisit that story.    

The state's failure to reach a budget agreement has caused a government shutdown, and now top officials are hashing out in court what exactly can and can't stay open.

At five CPS neighborhood high schools, students are earning college credit through a number of dual-credit courses. Those schools are also providing those students with a focused education on the science, technology, engineering, and math fields, or STEM for short.

Chicago Public Schools was able to make its $634 million pension payment on Tuesday after using borrowed funds and cutting 1,400 jobs.

We talk with Chicago Tonight correspondents Carol Marin and Amanda Vinicky.
