Happy New Year! This week, the Unexpected Elements team is reflecting on 2024 and looking forward to 2025 for renewed chances to spot the northern lights while they're at their peak visibility in this current solar cycle, and we recap on cellular regeneration advancements and regulations in embryonic stem cell models. 

We chat to Professor Rene Oudmaijer from the Royal Observatory of Belgium who explains that stars also renew themselves... and this process is key to our lovely planet (and ourselves) existing!  

We also learn all about the potential of bogs and wetlands in the fight against climate change from Professor Christian Dunn of Bangor University. 

With another amazing year behind us, we reminisce about our favourite stories and listener correspondences in 2024. 

And finally, we’re wowed by the regenerative ‘superpowers’ of the magnificent axolotl who has the cellular capabilities to re-grow limbs! 

That, plus many more Unexpected Elements.
