Mindfulness meditation, which involves becoming aware of the breath in the present moment, has been a core part of Eastern contemplative practices for thousands of years. Over recent decades however, it’s ‘exploded’ throughout the West as scientists have sought to prove the physical and mental benefits of regular practice - like feeling calmer, less stressed and feeling better able to manage emotions.

This week we look at some of the more surprising places where these simple techniques are having a big impact.

In Kenya, we learn about the ‘mindfulness revolution’ that took place in a men’s high security prison outside Nairobi after a group of inmates and guards were taught mindfulness techniques in 2015. They soon started teaching each other and ten years later it’s spread to prisons throughout the country and beyond.

And we visit Baltimore in the US, where a non-profit organisation has been teaching mindfulness and yoga in inner city schools for over twenty years, giving children growing up with violence and deprivation the tools to manage their emotions and heal trauma.

During the 1970s and 80s, thousands of Chilean babies were illegally kidnapped, trafficked and adopted. The practice was widespread during the rule of General Augusto Pinochet, who encouraged overseas adoptions to reduce poverty. A network of adoption brokers, hospital staff, social workers, judges, priests and nuns facilitated this trafficking.

Today many of Chile’s ‘stolen children’ are trying to trace their birth families - and their mothers are also looking for them. Hundreds of them have been successfully reunited with the help of a small Santiago-based NGO called Nos Buscamos. Using DNA testing kits, and a range of other techniques and technologies, they help track down families separated for decades. We meet Constanza del Rio - the founder of the project - and hear from the families they’ve helped to bring back together.

From Malawi, Myra Anubi takes a look at ways that technology is improving children’s education. Malawi has free primary schools - but almost 90% of 10 year olds are unable to read properly. So the government is distributing tablets to schools up and down the country. They use software that helps kids to learn maths and reading at their own speed and in their own language. Tests have shown that literacy and numeracy are improving and the children come to school more often.

Myra also visits the world’s first 3D printed school. In Malawi there aren't enough school buildings. Is 3D printing the solution to bringing better classrooms to where they are most needed?
