In 1975, San Diego Zoo began placing tissue samples of rare animals in cryogenic storage for the benefit of future generations. Called the Frozen Zoo, the refrigeration system now contains the cells of more than 1000 species ranging from the white rhinoceros to the black-footed ferret. Scientists are now using the collection to try to save species threatened by extinction. Simon Watts talks to Dr Oliver Ryder, who has worked at the Frozen Zoo from the very beginning.

Brenda Fassie: Madonna of the townships

In August 2002, the remains of an indigenous South African woman called Sarah Baartman were returned to South Africa after almost 200 years away. Sarah died in Paris in 1815 after being forced to perform in European 'freak shows' where people considered to be biological rarities were paraded for entertainment. She had been subjected to racist and degrading treatment and her remains were exhibited at a French museum until 1976.  When Nelson Mandela became the president of South Africa in 1994, he requested that Sarah's remains be returned to her homeland. However, by 1998 that had not happened. Poet Diana Ferrus decided to write about Sarah’s limbo. Her poem became so popular that it was noticed by politicians in France. Diana shares her memories of that time with Matt Pintus.

When South African schoolchildren marched in protest against having to study Afrikaans in 1976, they were gunned down by the police. The killings sparked a cycle of protests across the country against the racist apartheid regime. In 2010, march organiser Bongi Mkhabela told Alan Johnston about her memories of the Soweto uprising.

On 18 March 1992, white South Africans overwhelmingly backed a mandate for political reforms to end apartheid and create a power-sharing multi-racial government.  It was a high-stakes referendum coming on the back of three by-elections where the ruling National Party had lost to the right wing Conservative party.  In a speech after the polling victory, President FW de Klerk said: “Today we have closed the book on apartheid”. His communications adviser, David Steward speaks to Josephine McDermott.
