Matrescence, Mexico's 'searching mothers', New novel The Night Nag

The BBC has had exclusive access to the world’s largest study scanning pregnant women’s brains. The BeMOther project is based in Spain and has found that women's brains change significantly through pregnancy and beyond. We learn more about the changes and ask why Matrescence - and the transformations that can come with pregnancy, birth and raising a child - are only just starting to receive attention as a distinct life-stage. There's even a campaign to get the word in US dictionaries. Nuala McGovern talks to Smitha Mundasad, a BBC health and science reporter who visited the trial in Spain for her documentary, Baby Brain: What’s Really Going On? and Lucy Jones, the journalist and author of Matrescence: On the Metamorphosis of Pregnancy, Childbirth and Motherhood. Hester Musson’s latest book is The Night Hag. It’s a Victorian Gothic novel which takes place in 19th century Scotland. It delves into themes including the budding science of archaeology, spiritualism and folklore legends, but at its heart is the question of the role of women in Victorian society. A major global study says more than a quarter of healthy years lost to breast cancer could be prevented through lifestyle changes like cutting red meat, staying active and not smoking. The Lancet Oncology analysis shows cases worldwide are set to rise by a third, reaching over 3.5 million by 2050. We are joined by Professor Jayant Vaidya, Professor of Surgery and Oncology at University College Hospital, London, Dr Liz O'Riordan, a former breast cancer surgeon who herself has had breast cancer and is currently in remission, and Claire Rowney, Breast Cancer Now’s chief executive, who has been recently diagnosed with breast cancer. Last week, news broke of the killing of one of Mexico’s most dangerous men - known as El Mencho. He was killed by the Mexican military. He ran one of Mexico’s most powerful drug cartels, the Jalisco Cartel New Generation. In response, members of his cartel torched businesses and buses across the country. But among the burnt-out cars, a new wave of posters appeared, with the faces and names of some of Mexico’s 130,000 people who are either missing or disappeared – a tactic used by criminal cartels. The people taping their faces to walls are often their mothers, part of groups fighting to find out what happened to their loved ones. They are known as 'madres buscadoras' or searching mothers. Journalist Andalusia Soloff joins us from Mexico City, she has been following stories like these for years.Presenter: Nuala McGovern Producer: Helen Fitzhenry
