The first self-made female millionaire
Madam C. J. Walker was the first ever self-made female millionaire. She was born to former slaves in the USA and was orphaned at seven but against all the odds she went on to create her own business selling black hair-care products. By the time of her death in 1919 she'd become a famous philanthropist and civil rights campaigner. Claire Bowes has been speaking to her great great granddaughter A'Lelia Bundles.

The Way Ahead group: Modernising the Royal Family
Prince Harry and Meghan’s announcement that they will step back from their royal duties is not the first time the British royal family has tried to reform itself from within. In 1992 Queen Elizabeth had what she called her “annus horribilis” . It was the year that her sons Prince Charles and Prince Andrew both separated from their wives, while her daughter Princess Anne got divorced - and it was also the year that Windsor Castle caught fire. The Way Ahead group was set up by senior members of the royal family and some of their closest advisors to make sure that Britain’s monarchy stayed relevant in the modern age. Lucy Burns speaks to Charles Anson, who was the Queen’s press secretary at the time.(Photo: Queen Elizabeth II makes her "annus horribilis" speech at London's Guildhall, November 1992.

The frozen zoo
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.PHOTO: Northern White Rhino cells in the Frozen Zoo (San Diego Zoo Institute For Conservation Research)

How the dodo died out
A flightless bird, the dodo became extinct just decades after being discovered on the uninhabited island of Mauritius by European sailors. Because dodos couldn't fly they, and their eggs, were eaten by explorers and the cats and rats that came with them on board their ships. By the late 1600s there were none left. Simon Watts charts the demise and subsequent popularisation of the dodo.Image: An engraving of a dodo. Credit: Science Photo Library.
