This week, we’re looking at examples of innovative thinking in medicine. A new, non-invasive device could help people with paralysis to regain movement. And as Namibia passes a critical milestone, we look back on one of the biggest developments in preventing mother-to-child transmission of HIV.

Also on the programme, an update on the Korean doctors’ strike, and a summit looks to tackle the often-overlooked problem of indoor air pollution.
