Medicine and Science from The BMJ

Australia has been in the vanguard of legislation to try and reduce the influence of social media on children and young people - their ban for under 16s was introduced on the 10th of December 2025, to great fanfare, and a lot of interest around the world.

But how effective are these bans at keeping children away from social media?

New research just published on BMJ.com has looked at that question of efficacy - finding that children are using the most simple tactics to evade the ban.

To dicuss what that means, we're joined by two of the authors of that research Courtney Barnes and Luke Wolfenden from the University of Newcastle, Australia.

We’re also joined by Amrit Purba, from the London School of Hygiene and Tropical Medicine, and Louise Holly, from the Digital Transformations for Health Lab, in Geneva, who have written commentaries to go with that research.

The US military’s Operation “Epic Fury” highlighted the devastating cost of using artificial intelligence for rapid military planning. Thomas Adamkiewicz, associate professor at Morehouse School of Medicine, and Zulfiqar Bhutta, Robert Harding Inaugural Chair in Global Child Health at the Hospital for Sick Children, Toronto, to discuss why international humanitarian law is lagging dangerously behind technology, and why we urgently need a new era of legal frameworks to govern AI use in war.

 

Direct-to-consumer (DTC) advertising of prescription medicines is strictly illegal everywhere in the world except for the United States and New Zealand. Deborah Cohen, investigative journalist, joins us to explain how global social media platforms are making borders porous, allowing Hollywood celebrities and high-profile influencers to broadcast drug endorsements directly into the feeds of UK citizens.

 

Finally, Between 2020 and 2023, the UK government allocated £1.7 billion specifically intended for frontline doctor training. However, a deep-dive investigation has revealed that a staggering £400 million of that funding is completely unaccounted for - David Hutchison, paediatrics registrar, and Jonathan De Oliveira, GP trainee, join us to describe what they found.

The heated debate on prostate cancer screening boils down to one question: should men be routinely screened?

Two recent position statements from the UK’s national screening committee published in the BMJ show that screening decisions are steeped in complexity. 

The benefits of screening may be easier to grasp, but the harms of overdiagnosis and overtreatment are given less attention. Can we close the divide between the public and academic discourse?

 

Guest: Sian Taylor-Phillips is professor of population health at the University of Warwick and a member of the UK national screening committee.

New estimates of Global Patterns in Neonatal, Child, and Adolescent Mortality have been published - and while there has been a huge improvement, those gains are in danger - and we’re seeing worrying trends.

 

Kate Strong, a Scientist at the World Health Organization and Lucia Hug, a specialist in statistics and monitoring for UNICEF, join us to explain the data - and why they are worried about our ability to measure this in the future.

 

Helen Sharman is the first British Astronaut to make it to space - this week she was at the Royal College of GPs giving the General Medical Council's annual Marx lecture. She joins us to discuss how research in space might impact healthcare on Earth, and what the NHS can learn from cosmonaut teamwork. 

 

Finally, The government and doctors in England are not getting on well - we’ve had a series of strikes from the resident doctors, GPs are in dispute about the imposition of a new contract, and now consultants are being polled on industrial action.  BMA Consultants Committee co-chairs Shanu Dutta and Helen Neary explain why.

Does healthcare have a moral emergency?

In this episode of the Medicine and Science podcast, Kamran Abbasi sits down with healthcare leaders Maureen Bisognano, president emerita of the Institute for Healthcare Improvement and Bob Klaber, director of strategy at Imperial College Healthcare NHS Trust, to discuss why they're calling the lack of humanity in medicine an emergency.

We ask why this dangerous imbalance between the rational (efficiency, data, and metrics) and the relational (human connection, empathy, and listening) has developed in modern medicine. We also learn how simple changes, like asking "What matters to you?" instead of just "What's the matter?, can help us put the humanity back into healthcare.
