It's been 50 years since the American paleoanthropologist Donald Johanson discovered the fossil of ancient hominin 'Lucy' in the Afar region of Ethiopia. The find took the story of human evolution back beyond 3 million years for the first time. Yet, despite largely centring on the African continent as the "cradle of mankind", the narrative of hominin fossil discovery is striking for its lack of African scientists.
In this week's episode, Yohannes Haile-Selassie, director of the Institute of Human Origins at Arizona State University in the US, explains why the story of ancient human origins is so western-centric, and why he's calling for the decolonisation of paleoanthropology.

For generations, cod fishing was a way of life in Newfoundland and Labrador, the easternmost province in Canada. But in 1992, after cod stocks in the north Atlantic plummeted, the federal government imposed a moratorium on cod fishing. It was to last for 32 years until June 2024, when the government lifted the ban in a controversial decision.
In this episode we speak to Tyler Eddy, a research scientist in fisheries science at Memorial University of Newfoundland, to shed light on what’s happened. It's a story that offers a cautionary tale for those politicians trying to balance the complex demands of protecting ecosystems that also support substantial economies.

Take a walk along a beach in parts of South Australia, and you may come across unusual patches of pink sand. When a team of geologists began analysing samples of this mysterious sand to find out where it comes from, their search took them back through time to a previously undiscovered mountain range in Antarctica. In this episode Sharmaine Verhaert, a PhD candidate in earth sciences at the University of Adelaide, explains how the discovery was made.

A rare and ancient plant has been waiting for its long-lost mate. The only known specimens of Encephalartos woodii, a rare and ancient species of cycad, are male, all clones of the same plant found over 100 years ago deep in a South African forest. Now a team of researchers is on a mission to find an elusive female version of the plant with the help of drones and artificial intelligence.
In this episode we speak to Laura Cinti, a research fellow at the University of Southampton in the UK, about her determined quest to save the species – called the world's "loneliest" plant.

An epidemic of mpox in the eastern Democratic Republic of Congo, is spreading quickly, particularly among young children. Mpox is a serious, at times fatal, virus – and the world knows how to prevent it. There are effective vaccines stockpiled in many western countries. Yet, after an earlier global epidemic in 2022 was largely brought under control in Europe and North America, the ongoing battle to protect people in Africa from mpox was ignored.
In this episode we ask a virologist and a paediatrician why Africa's mpox crisis was so neglected and what needs to happen now to save lives, particularly children's.
Featuring Nadia Adjoa Sam-Agudu, professor of paediatric infectious diseases at the University of Minnesota in the US and Wolfgang Preiser, head of the division of medical virology at Stellenbosch University in South Africa, with an introduction from Nadine Dreyer, health and medicine editor at The Conversation Africa.

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.

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.

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.
