Joe Tidy travels to El Salvador where almost everything can be paid for using the cryptocurrency Bitcoin. After President Bukele invested heavily in Bitcoin some people are questioning the long-term impact of such a move. For some money has flowed in from mysterious investors, but others like local economist Tatiana Maraquin think the country’s economy cannot handle the fluctuations in the value of the cryptocurrency. Joe visits a veterinary surgery, which offers huge discounts on treatment if it is bought using the Chivo bitcoin wallet app. Presenter/producer: Joe Tidy (Photo: Bitcoin poster)

Adaptive fashion, or stylish clothes for people who have a disability have not always been widely available, especially for those who use a wheelchair. Recently though, a fashion revolution has begun. We hear from the women pushing the industry to change.

Samso controls its own energy supply and advises other communities on how they can do the same. And we find out about a project in Tanzania run by Janet Maro. Janet's project powers a centre for training farmers using experimental technology to harness the energy from the sun and collect rain water.Presenter / Producer: Laura Heighton-Ginns Image: Janet Maro and her team; Credit: Janet Maro

Singapore has become the latest country to allow egg freezing for non-medical reasons. That is a method of preserving a woman’s fertility so she can try and have children at a later date. With an increasing number of companies offering this and other fertility benefits as a workplace perk, Ivana Davidovic asks if this always good news for women?Carol Chen, a businesswoman based in Singapore, explains why she would have loved to have had a chance to freeze her eggs closer to home, rather than have to travel thousands of miles to the US to do the procedure there. She also hopes that other counties in Asia will soon make the process more streamlined Just under 40% of large companies in the US - so those over 500 employees - offer fertility benefits and the numbers are rising fast. Now even Europe, with its much more generous national health services, is starting to follow suit. Co-founder of a fertility benefit company based in Berlin, Jenny Saft, explains why.American entertainment lawyer Nyasha Foy tells her egg freezing story and the role that her employer played, while also considering specific issues faced by black women. Lecturer Lucy van de Wiel warns that employers having influence over their staff's fertility choices may not always mean good news for women.And Californian fertility doctor Aimee Eyvazzadeh, also known as the “egg whisperer”, talks about why she throws egg freezing parties and why we might need to accept that women will increasingly give birth in their 40s and 50s.Presented and produced by Ivana DavidovicImage: A woman injecting hormones in preparation for egg extraction.

Oil and gas prices have risen sharply after Russia’s invasion of Ukraine, and as a result many countries have signalled a move towards more renewable energy. One of the challenges for the future will be how to store energy produced by wind and solar power so it can be used at the right times. Professor Seamus Garvey and a team at the University of Nottingham tell us about their prototype machine which uses compressed air and heated gravel to tackle this problem. We also hear from Professor Mara Prentiss of the University of Harvard on the science behind these new ideas, and Heymi Bahar of the International Energy Agency to give an overview of this sector at the moment.

Dense tropical rainforest in central Africa's Congo Basin is humid and rainy for much of the year. Underfoot lies one of the world’s biggest carbon sinks – muddy soil built up from layers of partly decomposed plant matter. Remote and uncultivated, the peatlands have survived for thousands of years, stretching over an area the size of England. Incredibly, the area contains 30 billion tonnes of carbon trapped underground, but this rare carbon store is now under threat as local authorities turn their attention to oil.
