The light and smells in places like hospitals can often depress us. And, our favorite room at home keeps us sane. But why? Immunologist Esther Sternberg explains the scientific research revealing how physical spaces create stress and make us sick — and how good design can trigger our “brain’s internal pharmacies” and help heal us.

What happens when you bring together science and poetry on something like color or light? Arthur Zajonc is a physicist and contemplative. And he says we can all investigate life as vigorously from the inside as from the outside.

An unusual take on the mind-body connection with author and yoga teacher Matthew Sanford. He’s been a paraplegic since the age of 13. He shares his wisdom for us all on knowing the strength and grace of our bodies even in the face of illness, aging, and death.

Using stem cells, Doris Taylor brought the heart of a dead animal back to life and might one day revolutionize human organ transplantation. She takes us beyond lightning rod issues and into an unfolding frontier where science is learning how stem cells work reparatively in every body at every age.

With an Argentinean scientist, we explore the human landscape of forensic sciences and its emergence as a tool for human rights. Doretti has unearthed bones and stories of the dead and “the disappeared” in more than 30 countries, including victims of Argentina’s Dirty War, over two decades. She shares her perspective on reparation, the need to bury our dead, and the many facets of justice.

The American experience of stress has spawned a multi-billion dollar self-help industry. Wary of this, Esther Sternberg says that, until recently, modern science did not have the tools or the inclination to take emotional stress seriously. She shares fascinating new scientific insight into the molecular level of the mind-body connection.
