Chronic pain affects hundreds of millions of people around the world. But the opioid crisis in North America led many health care providers to realize they relied too heavily on drugs to help patients manage their pain.

In this episode, a pain management specialist discusses new developments in pain treatment and why there’s hope for patients with chronic pain. Rachael Rzasa Lynn Associate Professor of Anesthesiology, University of Colorado Anschutz Medical Campus speaks to Amanda Mascarelli Senior Health and Medicine Editor at The Conversation in the US about emerging chronic pain treatments.

Last month the United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its Synthesis Report of the Sixth Assessment Report. It showed global temperatures are now 1.1°C above pre-industrial levels. This warming has driven widespread and rapid global changes, including more frequent and intense weather extremes that are now impacting people and ecosystems all over the world. But when an extreme weather event hits, how certain can we be that it was made more likely by climate change? How do we know it wasn’t just a rare, naturally-occuring event that might have happened anyway?

Fear & Wonder is a new podcast from The Conversation that takes you inside the UN’s era-defining climate report via the hearts and minds of the scientists who wrote it. In this episode, we’re delving into one of the major shifts in the public communication of climate change – the attribution of extreme weather events to climate change.

Featuring Dr Friederike Otto, Senior Lecturer in Climate Science at the Grantham Institute at Imperial College London in the UK, David Karoly honorary Professor at the University of Melbourne in Australia, and Tannecia Stephenson, Physics Professor at the University of the West Indies, Jamaica.

Fear and Wonder is produced by Michael Green and is sponsored by the Climate Council, an independent, evidence-based organisation working on climate science, impacts and solutions.

The rise of drug-resistant infections is one of the biggest global threats to health, food security and development. Antibiotic-resistant superbugs were estimated to kill 1.27 million people in 2019, and the UN projects that drug-resistant diseases could cause 10 million deaths a year by 2050. In this episode, we hear from a microbiologist at a hospital in Nigeria working on the frontlines against antibiotic resistance, and find out about the new scientific techniques, including artificial intelligence, being deployed to find new potential antibiotics.

Featuring Nubwa Medugu, a clinical microbiologist at Nile University of Nigeria and André O. Hudson, dean of the College of Science and professor of biochemistry at Rochester Institute of Technology in the US.

Both the U.S. and China have plans to establish a permanent human presence on the Moon. You might be wondering: why now? The answer to that is the relatively recent discovery of water on the Moon. The question of how humanity will establish a Moon base is perhaps a deeper and more important one. We speak with two people, a planetary scientist who studies lunar geology and a scholar who works on space law and politics, about the challenges facing nations as humanity heads to the Moon.

Featuring Mahesh Anand, Professor of Planetary Science and Exploration at The Open University in the UK, and Michelle L.D. Hanlon, Professor of Air and Space Law at the University of Mississippi in the US.

If you like The Conversation Weekly, we encourage you to check out two limited series podcasts produced by The Conversation: Fear & Wonder and Great Mysteries of Physics. Available on Apple, Spotify, or wherever you like to listen to your podcasts.

It’s one of the biggest puzzles in cosmology. Why two different methods used to calculate the rate at which the universe is expanding don’t produce the same result. Known as the Hubble tension, the enigma suggests that there could be something wrong with the standard model of cosmology used to explain the forces in the universe. Now, recent observations using the new James Webb Space Telescope are shaking up the debate on how close the mystery is to being resolved.

In this episode, Vicent J. Martínez, professor of astronomy and astrophysics at the University of Valencia in Spain, and his former teacher, Bernard J.T. Jones, emeritus professor of astronomy at the University of Groningen in the Netherlands, explain why the Hubble tension matters so much for our understanding of the universe. Also featuring Lorena Sánchez, science editor at The Conversation in Spain.
