Sickle cell is an inherited blood disorder caused by abnormal red blood cells. It can cause sudden bouts of severe pain, as well as fatigue, a stroke, even death. It’s one of the most common genetic disorders in the world, but there’s still some stigma and a lot of misunderstanding around the condition.

We hear from Dunstan Nicol-Wilson, who was born with the condition, about what it’s like to grow up with sickle cell, and whether people’s attitudes are changing.

Around 80% of sickle cell cases worldwide are in sub-Saharan Africa. Makuochi Okafor, BBC Africa health reporter, tells us how it is inherited and what the symptoms can be. Nigeria has the largest population of individuals with sickle cell in the world, so he tells us how sickle cell is treated there.

Also last year the UK became the first country in the world to license a new gene-editing tool known as Crispr, as a treatment for sickle cell disease. Kesewaa Browne, a journalist in the U.K. tells us what treatments are already available and how Crispr could change things.

In 1980, Abebech Gobena was on a pilgrimage to Wollo in Ethiopia, when she witnessed the devastating effects of a severe famine and drought, one of the worst in the country's history. Within a year she had rescued 21 orphans and brought them to live with her in Addis Ababa. The organisation she founded has since raised thousands of Ethiopian orphans.

Dan Hardoon speaks to Hannah Merkana, one of the children raised in the orphanage, who considers herself one of Abebech's daughters.

Growing up in Devon’s sleepiest market-town, Mari has never felt she belongs. There’s the day-to-day trials that come with being a mixed-race kid in noughties rural England. And then there’s Baba, her larger-than-life Zimbabwean father – a local celebrity on the world music festival circuit.

Baba is desperate for Mari to learn his songs and follow in his footsteps, and Mari plays along. Literally. But she feels little connection to a country and a culture that Baba has always been strangely reluctant to talk about.

All that changes one blissful, teenage summer, when a daring distant cousin comes to visit from Zim. A fuse is lit in Mari that will blow the familiar certainties of her old life apart. When she swaps her dad’s world of festivals for uni in Plymouth, the town’s straight-talking, rough-edged gay scene offers a fresh sense of identity.

But will Mari’s new-found strength be enough to confront a dark family secret?

A story of multifaceted identities and what it means to truly make your own kind of music.

Emperor Haile Selassie fled to Bath in 1936, where he became "engrained" in the local community.

In 1936, Haile Selassie came to Bath in the west of England to escape Mussolini and the fascists who had invaded Ethiopia.

He bought a property – Fairfield House - and moved his entire family and staff there. He quickly became the talk of the town.

The local paper ran daily updates on the Emperor’s schedule and dispelled rumours such as the Emperor’s beard "having turned white with anguish" or that he was keeping lions in the basement.

Haile Selassie also made a point of indulging in local amusements and even took a trip to the Tropicana outdoor swimming pool in the seaside town of Weston-super-Mare.

Selassie returned to Ethiopia in 1940 after the British helped remove Mussolini. He never forgot his time in Bath and renamed one of his palaces Fairfield in tribute to the British city.

Presenter Myra Anubi visits western Kenya to see an innovative project that’s using hi-tech drones to deliver HIV drugs and testing kits. It’s an attempt to tackle the number of infections amongst young adults in the region. The drones are dropping HIV kits at youth-focused events such as football matches and concerts. The idea is to take away some of the stigma surrounding HIV/Aids and make treatment more accessible.

From the journey from cocoa to chocolate in Ivory Coast. The price of cocoa - the essential ingredient in chocolate - has more than quadrupled on the international market in the last two years. Yet many of those growing it have not benefitted. In fact, drought, disease and a lack of investment have led to catastrophic harvests and, therefore, a drop in income for many small producers of cocoa, especially in Ivory Coast. This West African country is the world’s largest producer of cocoa - up to 45% of the world’s total. Most of the growers are small-scale, poor farmers. There are now calls for these growers to get a bigger chunk of the chocolate bar and, in so doing, to help ensure future production. John Murphy travels to Ivory Coast to delve into the world of chocolate production.
