Editorial Reviews

Host Neil deGrasse Tyson will tackle one of science's major challenges in each episode framed as a simple question that ordinary people wonder and worry about. Neil will guide us as he explores dramatic discoveries and the frontiers of research that connect each central provocative mystery. Episode includes: 1) ORIGINS OF LIFE - Scientists have long argued that billions of years ago life emerged on its own - from the self-assembly of non-living matter but no knows exactly how. Now in landmark discovery chemist John Sutherland has created the conditions in which the building blocks of RNA - one of the key molecules of life and the probable precursor to DNA - assemble themselves naturally. 2) BIRTH OF THE SOLAR SYSTEM - Could the key to our solar system's existence be the epic explosion of an ancient supernova? Combining chemical evidence from meteorites with the latest computer simulations scientists show how nearly five billion years ago a supernova shock wave could have swept through a cloud of dust and gas and caused it to collapse eventually forming the sun and the planets. We also see amazing Hubble images of nebulae where the same cycle is happening today. 3) LICE AND THE HAIRLESS APE - Fossil hominid bones tell us a lot about human evolution but still leave many questions unanswered like when we lost our hair and started wearing clothes. Thankfully there's another source - even if it's kind of gross. Most people especially the parents of young children are sworn enemies of head lice but the creepy critters - who've been sucking our blood for millions of years - are suddenly proving their value. Their DNA turns out to hold a treasure trove of clues about our evolution. 4) PROFILE: ANDRE FENTON - Can a simple injection erase a painful memory? Andre Fenton (SUNY Downstate) who grew up in Guyana South America says it can. But he isn't in the business of wiping out personal histories. He hopes that his work can help people struggling with dementia and Alzheimers and one day illuminate the biological root of memory itself.

I must confess that I am not a scientist. I majored in philosophy and took entomology to meet my science requirement in college. I got lucky here because lice play a major role in this DVD. Instead of trying to explain everything on this DVD, I will list the major topics found on it: meteorites, asteroids, Arizona desert, Iron 60 from a supernova, DNA and RNA, Charles Darwin, precooking in volcanic vents, mutations, sensory deprivation, neuroscience and rats, PKM ZETA and hippocanthus.
If you the reader find any of these topics interesting, get this DVD, then write a review for all of the philosophy majors on Amazon.

How do you combine studying the origin of our solar system, the start of life itself, what head, body, and pubic lice tell us about human evolution, and building/erasing memories? Neil Degrasse et al manage to do it in 60 minutes, while both educating and keeping one interested every minute. It's amazing what meteorites, rat research, and lice DNA can tell us about complex, long, long ago topics.

Great visuals and reinforces the curriculum. Nova keeps up with the topics that we needs to teach effectively and grabs the attention of our students.
