Today we’re talking talc… that white powder that is sometimes found in make-up. There’s been a lot of chat recently about the safety of talc. So, in this episode we find out why it’s in our make-up and cosmetics, and whether we should be avoiding it.

BBC journalist Phoebe Keane, who produced the podcast series Talc Tales, explains what talc is and its link to asbestos, a known carcinogen. We also discuss the different tests that are used to determine if talc has been contaminated with asbestos.

The World Health Organization has classified talc as “probably carcinogenic to humans”. Several companies, including Johnson & Johnson, Chanel and L’Oreal have been quietly moving away from using talc-based products in recent years. But do consumers care about this? We hear from Savannah, a PhD student and make-up content creator. And what can you use if you want to avoid talc in make-up? Jen Novakovich, a science communicator and cosmetic scientist, suggests some alternatives.

Hippos were first introduced to Colombia by drug lord Pablo Escobar. After his death in 1993, the hippos were left roaming free on his abandoned estate and their population kept on growing.

Colombia is the only country outside of Africa with a wild hippo population and they’ve become a tourist attraction there. But like other invasive species, they are an issue - tearing through villages and competing with native wildlife. The government has tried sterilising and relocating them but this has been expensive and unsuccessful. So now, they’ve decided to cull around 80 hippos to limit their growth but animal rights groups think other options might still be possible.

We speak to the BBC’s Climate and Science reporter, Esme Stallard, who explains how these decisions are made and why invasive species can be such an issue. And we hear from Manuel Rueda, a freelance journalist in Bogota, who has previously visited the hippos.

India has the biggest youth population in the world and more and more people are graduating from colleges and universities. 5 million people are coming out of education each year, but nearly 40% of graduates aged between 15-25 can’t get a job. In fact, the unemployment rates are way higher for graduates than for people who are less educated.

White-collar job creation - graduate office jobs - has fallen from 11% growth before 2020 to just 1% today, according to Naukri Jobspeak Index. Big employers like Tata Consultancy Services, Infosys and Wipro are all cutting jobs or freezing recruitment. And AI is also playing a role here. The Indian government estimates that by 2031, AI could eliminate close to three million IT and customer service jobs.

So what’s it like to be an unemployed graduate in India right now? How do you get through the daily grind of job applications and interviews? How do you deal with pressure from your family to find a job? We chat to Karmanya Batra, Anjali Mekala and Bhadra Ashok Kumar.
