This is a re-airing of a podcast originally released in February 2021.

Keeping you cosy this week is an episode all about warmth - emotional, physiological and geological.

We have an unexpected start to the show, with bees taking the spotlight, but it turns out these cold-blooded little insects can generate immense warmth when necessary.

The team then takes a much bigger view of warmth, discussing the heat of the planet, and of the many uses of geothermal energy.

Finally they wrap up by finding out what it takes to make a robot seem warm and friendly.

On the pod are Rowan Hooper, Anna Demming and Timothy Revell. Find out more at newscientist.com/podcasts
