Last year in Italy the biggest anti-mafia trial in 30 years reached a climax. On the stand were the Calabrian ‘Ndrangheta: they are estimated to run 80 percent of Europe’s cocaine and to make more money in a year than McDonalds and Deutsche Bank put together. With access to mafioso-turned-collaborator Emanuele Mancuso, journalist Francisco Garcia looks at why Emanuele testified against his powerful family. What has this trial meant for the 'Ndrangheta? And has it changed life for Calabrians today?

The number of labels to describe different types of mental disorder has mushroomed in recent years. New categories include Oppositional Defiant Disorder, Prolonged Grief Disorder and Mild Cognitive Impairment. Many classifications have been created or influenced by a book called the Diagnostic and Statistical Manual of Mental Disorders (DSM). Advocates of DSM say labels help people take ownership of their situation, provide them with answers, treatments and social support. Critics think it creates stigma, medicalises normality and leads to a glut of unnecessary and harmful drug prescriptions. UK based musician Jay Emme asks if labels help or hinders in everyday life and whether it’s time to drop the terms ‘mental’ and ‘disorder’?

Hearing how North Koreans in the Hwanghae Province suffer from food shortage, he started throwing bottles filled with rice and a USB stick into the Yellow Sea, hoping they would land on North Korean shores.

Vast areas of the southern Brazilian state of Rio Grande do Sul remain under water after the worst flooding in 80 years. Homes have been destroyed, thousands are without power or drinking water, and entire towns remain cut-off. The torrential rains began in Rio Grande do Sul at the end of April, saturating the ground and bursting the banks of the Taquari and Caí rivers. Those rivers flow into the Guaíba, which has led to severe flooding in the state capital, Porto Alegre. We bring together three residents of Porto Alegre and volunteer rescue workers to share their experiences of the flooding.

When Father Père Basile was 12 years of age, he started thinking of a religious life. But it never crossed his mind that he would someday be living in a cloistered abbey in the south of France producing wine. This monastery has incredible history as it is the site of the oldest papal vineyard in the world, dating back to the 14th Century. When Pope Clement V moved the papal capital from Rome to Avignon in France, his palace needed a steady stream of wine and so the vineyard was planted in Le Barroux. Presenter Colm Flynn travels to the abbey to meet Fr Père Basile, and hears his amazing story of growing up as the son of wealthy, world-travelling diplomats, and turning his back on that to pursue a deeper calling in life.
