Peter Mwai, a BBC reporter from Nairobi, explains how misinformation is driving a series of conspiracy theories.

There are so many foods and substances that people can be allergic to; peanuts, cows' milk, eggs, pollen, or animals. Even mangoes or bananas.

We are so much more aware of allergies now but there is also evidence that more people than ever have allergies. BBC journalist Frances Mao talks us through what allergies are - and why more of us are suffering with allergies. She also tells us about some new treatments being tested to treat them.

Australia is now described as the allergy capital of the world. Frances (who grew up in Australia) explains why. And Professor Kirsten Perrett, Director of the Australian National Allergy Centre of Excellence, tells us about the role of Vitamin D.

If you’ve got a serious allergy, it can be really stressful managing it and making sure the stuff you eat and come into contact with isn’t going to harm you. We hear from Mia Silverman (@AllergieswithMia) who is based in the US and allergic to 50 different food types.

And Maria Clara from the What in the World team tells us what it’s like to have immunotherapy for an allergy.

DeepSeek, a Chinese AI chatbot launched last week, has shaken up the tech world and fuelled a new AI race between China, Europe and the US. The creators of the app say that it cost just $6 million to make compared to the billions spent by giants like Microsoft and Google. Amid the buzz surrounding this new chatbot, there are concerns about security, personal data and censorship.

BBC’s cyber correspondent Joe Tidy explains what DeepSeek is and assesses the impact it’s had so far.

We also hear from Benny Lu, a BBC Chinese reporter based in Hong Kong. He tells us about the concerns that people in Taiwan have over the use of Chinese technology.

Huge clashes are taking place in the DRC, with the Congolese army facing the rebel group M23. M23 claims to have taken over the city of Goma in the eastern part of the country.

UN aid agencies say there are hundreds wounded, bodies in the streets, and an increase in rape and gender-based violence. The UN has long said M23 is backed by Rwanda, but the Rwandan government has always denied this.

The DRC is not unfamiliar to violence. The conflict has roots stretching back at least three decades. The country has huge amount of natural resources, with many trying to take advantage of it, including armed groups. BBC Monitoring journalist, Sam Lando in Nairobi takes us through the background to what’s going on.

2025 marks 80 years since the liberation of the Auschwitz-Birkenau death camp. It was at the centre of the Nazi campaign to eradicate Europe's Jewish population, and almost one million of those who died there were Jews - but Poles, Roma and Russian prisoners of war, among many others, also perished at the camp.

Memorials, historical documentation and testimony from survivors help preserve this troubled history. But disinformation and cultural amnesia mean many people deny that the Holocaust happened.

We hear from BBC presenter Jordan Dunbar, who visited the Auschwitz-Birkenau camp in Poland for a BBC documentary. He has been speaking to survivors of the Holocaust. He tells us about how this disinformation is spreading online, and what’s being done to preserve accurate accounts of history.

Plus, we also hear from Andy Pearce, an associate professor and historian at University College London’s Centre for Holocaust Education, about how to approach conversations where Holocaust misinformation or denial is present.

Dugongs are grey sea mammals, also called “sea cows”, partly because of how they look and because they graze on seagrass. The dugong can be found off the coast of 48 countries between East Africa and Vanuatu in Oceania. They are listed as Vulnerable on the IUCN Red List of Threatened Species.

There used to be common sightings off the coast of Thailand but now, at least 70 dugongs have been found dead along the southern coast of the Andaman Sea over a period of 22 months. In October 2024 alone, 30 dugongs were reported dead in Thailand. What’s behind this?

Panisa Aemocha from BBC Thai, explains the importance of dugongs to local eco-systems and why their numbers are declining. We also hear what the Thai government is trying to do to save them.

Numbers have also gone down in East Africa. Evan Trotzuk from the African Parks NGO, explains why and tells us about the measures being taken to protect dugong in Bazaruto Archipelago National Park, Mozambique.

There are about 12 million Uyghurs, mostly Muslim, living in Xinjiang. China has been accused of committing crimes against humanity and possibly genocide against them. This includes the use of ‘re-education camps’ to eradicate Uyghur identity and culture. China denies any human rights abuses.

Many Uyghurs have fled to countries including Turkey and Thailand. But once they get there they face new challenges. Shawn Yuan, a journalist from the BBC’s Global China Unit, joins us to explain why. We also hear why some Uyghurs in Thailand could face being sent back to China.
