Dec 4, 2013 — Is the brain a sort of quantum computer? What is consciousness? Marcelo Gleiser's brain is buzzing with big questions after participating in a conference that asked if quantum physics plays a role in how we think.
Nov 22, 2013 — What is a brain but a cloud of elementary particles? If that's the case, then isn't the world a just figment, an image or a confabulation? Commentator Alva NoŽ asks if our world, the world described by science, is any more real than the stories in the Bible.
Nov 20, 2013 — Life on Earth is connected to the stars in ways we couldn't imagine a thousand years ago. Physicist Marcelo Gleiser says the journey to understanding our relationship with the cosmos has transformed how we see ourselves and all that surrounds us.
Nov 19, 2013 — When Philip Gould knew the end was coming, he managed to use his predicament as a catalyst for seeing life more clearly. A film documenting his final days also opened commentator Adam Frank's eyes. What will it do for you?

Oct 11, 2013 — Do dogs think and feel? Are they persons? And if you are unsure, would the results of brain studies on dogs help you make up your mind?

Sep 29, 2013 — Can everything that happens in the universe (like the working of your mind) be understood merely as an expression of interactions at the level of elementary particles? Astrophysicist Adam Frank doesn't think so. He's skeptical of reductionism and takes heart from a new theory that sees cause-and-effect flowing both ways.
