Reproductive biologist Professor David Gardner explains what we're still learning about healthy embryo development, how it's being applied to improve IVF technologies, and the unexpected insights it may offer into how cells implant themselves and proliferate -- including how cancers take hold. Presented by Dr Andi Horvath.
Ecologist Prof. Peter Vitousek explores how living in the Anthropocene, a time in which human activity has become the key driver of planetary health, will force us to make our way with diminished natural resources. Peter also asks what we can learn from the historical experience of Pacific Islanders, whose cultural and agricultural practices were shaped by a profound understanding that their immediate horizons were in fact the very limits of their worlds. Presented by Dr Andi Horvath.
Environmental law researcher Erin O'Donnell and economist Julia Talbot-Jones explain what's behind recent moves to give legal personhood to rivers in India, New Zealand and elsewhere. With philosophical roots going back decades, new legal and legislative developments granting personhood to nature seek both to recognise indigenous or religious claims as well as provide new avenues for environmental protection. But what does this mean, and how will giving rights to nature be enforced? Can rivers now bring lawsuits, and can we, in turn, sue them? Presented by Lynne Haultain.
Economist Dr Lauren Johnston examines the evolving political and economic relationships between China and Africa, and how the East Asia giant is adapting its own model of aid, trade and investment to grow regional African markets and economies while securing a rising supply of energy and mineral resources for itself. Presented by Peter Clarke.
Population health researcher Professor Cassandra Szoeke outlines what ails women as they grow older, how men differ from women in age-related diseases, and how public awareness and personal lifestyle change have been shown to have a positive impact on women's quality of life in their later years. Presented by Dr Andi Horvath.
Geriatrician Professor Andrea Maier describes what happens to our cells as we age, and explains the causes of age-related diseases. She also discusses how positive lifestyle choices and preventive medical interventions can help us live healthier for longer. Presented by Dr Andi Horvath.
Sustainable agriculture expert Prof Tim Reeves discusses the profound changes required in agricultural practice, public policy and consumer behavior if we are to feed earth's ever-growing human population that is projected to exceed 9 billion in 2050. Business as usual won't pass muster anymore. With host Dr Andi Horvath.
Governance expert Prof Minxin Pei describes how collusion between China's political and business elites have resulted in the privatization of public assets for enormous personal gain. He also explains why the current crackdown on corruption is but a band-aid and that a free media and liberal democracy may be the key elements to a lasting solution. Presented by Peter Clarke.
Psychiatric epidemiologist Professor Michael King discusses the devastating psychological harm suffered by victims of homophobia and transphobia. He also examines the role of families, governments and religion in curbing the problem. Presented by Lynne Haultain. 
Molecular biologist Prof Jacob Corn describes how gene editing is carried out with CRISPR-Cas9. He explains why this technology has the potential of revolutionizing the treatment of diseases such as sickle cell anemia and malaria. Besides human health, CRISPR-Cas9 can also contribute to improving agriculture and, consequently, food security. Jacob also discusses the possible ethical challenges posed by the widespread application of gene editing. Presented by Dr Andi Horvath.
