A ground-breaking new medical trial has begun in the UK aimed at slowing the progress of multiple sclerosis. The Octopus trial is looking into whether existing drugs can be repurposed to help slow the progression of the condition. Alykhan, who was diagnosed with MS when he was still at school, is taking part in the study. He joins us in conversation with Professor Jeremy Chataway, from the National Hospital for Neurology and Neurosurgery in London, who is leading the trial.

In the heyday of the Sikh Empire, Kirtan (Sikh hymns) were performed using stringed instruments such as the sarangi, rabab and taus. The rich, complex tones these instruments create are said to evoke a deeper connection to Waheguru (God). But in the late 19th Century, these traditional instruments were replaced by European imports like the harmonium. Now a new generation of diaspora Sikhs is painstakingly rebuilding that musical heritage - restoring scores and meeting up to teach and learn traditional instruments. Monika Plaha meets one these musical pioneers, Harjinder Singh Lallie, and finds out how his beliefs fuel his work and how his music shapes his faith.

The Gran Chaco Forest is Latin America’s second largest ecosystem. It is a mix of hot and arid scrublands, forests and wetlands, part of the River Plata basin, so large it extends into Paraguay, Brazil, Argentina and Bolivia. Large parts of the forests have already been cleared to make way for farms. Now a new highway being driven through it is heralding further change. The so called Bioceanic Corridor will transport the produce of cattle ranchers and soya-bean farmers in Brazil and Paraguay across to ports on the west coast. Members of some indigenous communities like the Ayoreo see it as a further threat to their way of life. The new road is being cautiously welcomed by some members of the Mennonite Community, a Christian religious group who came to the Gran Chaco 100 years ago via Prussia, Russia and Canada and bought land from the government to farm. Will the impact of the road on the indigenous and Mennonite communities - and the environment - be worth the economic benefits? Jane Chambers travels across the Gran Chaco for Assignment. Produced by Bob Howard. The Paraguay producer was Santi Carneri.
