Laura Cinti, a research fellow at the University of Southampton, is on a mission to save the world's 'loneliest' plant, Encephalartos woodii, which has no known female counterpart. She discusses the challenges of locating this ancient cycad, all while employing cutting-edge drones and AI technology. Cinti shares compelling anecdotes about the detective work involved in this quest and emphasizes the urgent need for biodiversity conservation. This intriguing conversation highlights the intersection of science and art in preserving our planet's unique flora.

Join virologist Wolfgang Preiser and pediatrician Nadia Adjoa Sam-Agudu as they discuss the ignored epidemic of mpox in the Democratic Republic of Congo, which is devastating young children. They reveal how existing vaccines are stockpiled in the West while Africa suffers. The conversation highlights the urgent need for child vaccination, treatment options, and a shift towards equitable health practices. Their insights emphasize the tragic consequences of global health neglect and call for immediate action to save vulnerable lives.

Dating apps are having a rocky moment, with some of the biggest struggling to attract paying users. In this episode, we hear from researchers exploring how dating apps have changed modern dating and the expectations around it. And we find out why some dating app users aren’t actually there looking for love, but keep on swiping anyway.Featuring Treena Orchard, associate professor at the School of Health Studies at Western University in Canada, and Carolina Bandinelli associate professor in media and creative industries at the University of Warwick in the UK.This episode was written and produced by Mend Mariwany, with assistance from Katie Flood and sound design by Michelle Macklem.

In the second of two episodes on geoengineering, we hear the case against trying to reflect sunlight to cool the Earth.Solar radiation modification has attracted attention and investment in recent years as a way to potential reverse the effects of climate change, but it remains a controversial idea.We hear from researchers pushing a non-use agreement for solar geoengineering who explain why they believe these types of technologies are a dangerous distraction from what needs to be done to reduce fossil fuel emissions. Featuring Chukwumerije Okereke, professor in global governance and public policy at the University of Bristol, and Co-Director at the Center for Climate Change and Development at Alex Ekwueme Federal University in Nigeria and Aarti Gupta, professor of global environmental governance at Wageningen University in the Netherlands.

Geoengineering, the modification of the climate using technological interventions to reverse climate change, is a hugely divisive issue and we’ve decided to explore it in two episodes. In this first episode, we talk to scientists working on potential geoengineering technologies who argue the case for conducting research into these interventions. We speak to Shaun Fitzgerald, director of the Centre for Climate Repair at the University of Cambridge in the UK and Hugh Hunt, deputy director at the Centre, as well as Ben Kravitz, assistant professor of Earth and atmospheric sciences at Indiana University in the US. We're also joined by Stacy Morford, environment and climate editor at The Conversation in the US.Part two, out tomorrow, will focus on the case against a particular type of solar geoengineering called solar radiation management. This episode was written and produced by Katie Flood, Mend Mariwany and Gemma Ware, with sound design by Michelle Macklem. Our theme music is by Neeta Sarl.

As we take a short production break in August, we're re-running an episode from 2023 about Neanderthals, and what new discoveries about their research could tell us about Homo Sapiens. For generations, Neanderthals have been a source of fascination for scientists. This species of ancient hominim inhabited the world for around 500,000 years until they suddenly disappeared 42,000 years ago. Today, the cause of their extinction remains a mystery.Archaeologist Ludovic Slimak at the University of Toulouse III, Paul Sabatier in France and his team have spent three decades excavating caves, studying ancient artefacts and delving into the world of Neanderthals and they've recently published provocative new findings. He tells us more about how Neanderthals lived, what happened to them and why their extinction might hold profound insights into the story of own species, Homo Sapiens.This episode was produced and written by Mend Mariwany with assistance from Katie Flood. The executive producer was Gemma Ware. Sound design was by Eloise Stevens and our theme music is by Neeta Sarl. Full credits for this episode are available here. A transcript is now available.

As The Conversation Weekly takes a short production break in August, we're bringing you a recent episode from our partners at the Borders and Belonging podcast about Japan’s evolving stance on immigration.With a rapidly ageing population and a shrinking workforce, Japan is facing an unprecedented crisis: by 2030, it's projected to have a shortfall of nearly 6.4 million workers. But despite Japan’s reputation for being closed off to migrants, there are signs that the country’s national immigration policy is starting to shift.Each episode of Borders and Belonging takes an in-depth look at a different regional migration issue and puts it into a global context. They do this through interviewing people with deep knowledge and experience of the region, including a couple of academic experts. The show is hosted by Maggie Perzyna, a researcher with the Canada Excellence Research Chair in Migration and integration programme at Toronto Metropolitan University in Canada.This episode features Nicholas A. R. Fraser, a senior research associate at Toronto Metropolitan University, Ito Peng, professor of sociology and public policy at the University of Toronto and Nana Oishi, associate professor in Japanese Studies at the University of Melbourne.Borders and Belonging is produced by CERC Migration in collaboration with Lead Podcasting. Sound design for this episode of The Conversation Weekly was by Michelle Macklem, with production by Mend Mariwany. Sign up for a free daily newsletter from The Conversation and to support what we do, please consider donating to The Conversation.

Momentum is growing against clauses in investment treaties that permit companies to sue a state if it decides to keep fossil fuels in the ground. In this episode, we revisit the secretive world of investor-state dispute settlement (ISDS), which some experts are worried could jeopardise global efforts to save the climate and cost countries billions of dollars in the process. Kyla Tienhaara, Canada research chair in economy and environment at Queen's University, Ontario in Canada, comes back on The Conversation Weekly to update us on the latest resistance to these clauses. Part of this episode was first aired in October 2022. You can listen to the original episode here. It was produced by Gemma Ware and Mend Mariwany, with sound design by Eloise Stevens.
