An ambitious new government-led research initiative aims to fully map the human brain. The goal is to advance understanding of how the brain works and develop treatments for crippling neurological diseases. But for researchers, the Holy Grail is to understand the origins of human consciousness. Two leading neuroscientists join us to talk about this potentially groundbreaking project.

American astronaut Scott Kelly has allowed the human race an opportunity to live vicariously through his #YearInSpace travels by sending global images back to Earth through his Twitter and Instagram feeds. Sent from day 189 of his 12-month mission, Kelly shared this astonishing nighttime view of Chicago from space on Oct. 2.

When we think wildlife, most of us think national parks and far-off forests. But an interactive science project called Chicago Wildlife Watch wants to show us that wildlife is, quite literally, right in our own backyards and outside our high-rise balconies. Seth Magle, director of the Urban Wildlife Institute at the Lincoln Park Zoo, tells us about Chicago Wildlife Watch and how we can all answer the call of the wild.
