Sleep is one of the most important aspects of our life, health and longevity and yet it is increasingly neglected in 21st century society, with devastating consequences: every major disease in the developed world - Alzheimer's, cancer, obesity, diabetes - has very strong causal links to deficient sleep. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why its absence is so damaging to our health. Compared to the other basic drives in life - eating, drinking and reproducing - the purpose of sleep remained elusive.

Nobel Prize winner Dr Elizabeth Blackburn and leading health psychologist Dr Elissa Epel have discovered biological markers called telomeres, which can help us to understand how healthy our cells are and what we can do to improve them. The Telomere Effect looks at ideas including how biological age is not chronological age, a biological basis for the mind-body connection and how sleep and diet can affect telomeres.

In Mitochondria and the Future of Medicine, naturopathic doctor Lee Know tells the epic story of mitochondria - the widely misunderstood and often-overlooked powerhouses of our cells.

Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy.

Ageing - not cancer, not heart disease - is the world’s leading cause of death and suffering. We accept as inevitable that as we get older our bodies and minds begin to deteriorate, and we are increasingly likely to be struck by dementia or disease. Ageing is so deeply ingrained in human experience that we never think to ask: is it necessary?
