    How do you convert CO2 to rock?

    11/03/2026 | 13 mins.
    We're living in an age of rapid technological development which - alongside many benefits - comes at an environmental cost. We speak to Dr Shurui Miao, an experimental chemist who aims to decouple technological advancement from the impacts of increased carbon emissions, by finding a way to safely store carbon underground. As he explains, by finding a way to convert CO2 from the atmosphere into minerals, we could store carbon securely and sustainably into the future, and ultimately begin to mitigate the effects of climate change.

Milk on the Move explores milk's deep cultural roots, evolving scientific narratives and the systems that shape its production today. Hosts Johanna Zetterstrom-Sharp and JC Niala uncover the fascinating interaction of tradition, knowledge and morality that makes milk so much more than just an everyday drink. Available on Apple Podcast, Spotify or head to milkingit.org for more information.

    What was Einstein doing in Oxford?

    25/02/2026 | 11 mins.
    If you've had the chance to visit Oxford's History of Science Museum, you may have found yourself gazing upon a rather special blackboard. Featuring equations that connect the age, size and density of the Universe, the penmanship is that of Albert Einstein himself, who used the blackboard during a lecture on 16th May 1931. But what was Einstein doing in Oxford, and how did he spend his time there? We chat to Dr JC Niala, Head of Research, Teaching and Collections at the History of Science Museum, to find out more about the man (and musician!) behind the genius. 
    Dr JC Niala also hosts her own brilliant podcast, alongside Dr Johanna Zetterstrom-Sharp, called 'Milk on the Move'. You can listen to an episode ('Purity and Danger') right here on our playlist, or find out more at milkingit.org.

    Where do baby penguins come from?

    11/02/2026 | 15 mins.
    For this year's Valentine's Day episode, we are getting up close and personal with those most beloved of birds - penguins. Giving us an insight into the love lives of our feathered friends are penguinologists (yes, that's a real word) Dr Ignacio Juarez Martinez and Dr Fiona Suttle, who have both graduated from Oxford's Department of Biology, and spent multiple field seasons in Antarctica monitoring penguin breeding behaviour. We hear how penguin breeding patterns appear to be shifting with changing temperatures, and how you can get involved in their research - just head to Penguin Watch to take part.

    How can I use AI to raise my salary?

    28/01/2026 | 13 mins.
    How much more money could you earn - doing the exact same role - if you're in possession of some solid AI skills? That's one of the core questions that Dr Fabian Stephany, a researcher at the Oxford Internet Institute, hopes to answer. Leading the 'SkillScale' project, Fabian looks into the impact of AI tools on the labour market, with the ultimate hope of advising workers on the best ways to secure jobs and increase their salaries. So, far from a discussion about 'AI stealing our jobs', we ask Fabian - how can we use AI to secure a bigger pay packet?
