Closer to a cure for morning sickness
Morning sickness affects 4 in 5 women at some point in pregnancy but until now we’ve known little about why. Now researchers in the USA, Sri Lanka and the UK have discovered that it could be linked to a hormone produced in the placenta, and the mother’s reaction to it. Dr Graham Easton explains how it could lead to new cures. He also brings Claudia Hammond news from Ukraine where the ongoing war has caused an increase in multidrug-resistant organisms. The US Center for Disease Control and Prevention, and the Center for Public Health of Ukraine are calling the spread of antimicrobial resistance in Ukraine an urgent crisis. People living in Port Sudan, the country’s biggest sea port city, have spent days struck by an unprecedented infestation of flies.

New Zealand backtracks on smoking ban
When former Prime Minister of New Zealand Jacinda Ardern passed legislation to reduce access to tobacco products, the policy was held up as an international example. So there was shock among health experts in New Zealand and across the world this week when the newly sworn in Government announced they would be scrapping the plans. Claudia Hammond asks Janet Hoek, Professor of Public Health at the University of Otago what the international impact will be.

Gene editing treatment approved for sickle cell
The UK has become the first country in the world to approve a gene editing treatment for people with the genetic conditions sickle cell disease and beta thalassemia. The news has been hailed as revolutionary, unthinkable just a decade ago. But will the new treatment provide a realistic option for the millions of people living with these haemoglobin disorders worldwide? BBC health reporter Philippa Roxby joins Claudia to look at the latest. She also brings new evidence from Australia on the health benefits of delayed cord clamping to new born premature babies. And a study drawing attention to the impact of surfing on surfers’ mental health. Could it add billions of dollars to the world economy? Losing a family member is a difficult experience for everyone but for people who no longer have a connection to the person who has died, it can cause a mixture of grief, sadness, guilt, or relief. Claudia talks to broadcaster and author, Professor Alice Roberts, about her experience of losing her mother after being estranged for 5 years. In the week that the World Health Organisation announced a new focus on the health impacts of loneliness, we noticed a familiar comparison in the headlines; that the health risks from being lonely are equivalent to smoking fifteen cigarettes a day. But what does that really mean? Claudia asks Professor Andrea Wigfield, Director of Centre for Loneliness Studies in the UK. Presenter: Claudia Hammond

Vaccinating children against chickenpox
The committee that advises on vaccinations in the UK has recommended that chickenpox is added to the standard list of childhood vaccinations; something which the USA and many European countries have been doing for some time.

They also hear from conversation analyst Charlotte Albury, a Senior Research Fellow at the University of Oxford, about how doctors communicate with patients with obesity can have a significant impact on their weight loss success. And with shortages of doctors in many parts of the world, are shared medical appointments - where a group of patients with the same condition see a doctor together - the answer? As Anupama Chandrasekaran reports from India, a trial carried out at Aravind Eye Hospital by ESMT Berlin, Harvard Business School and London Business School, found some surprising results.
