Hello and welcome to Mysteries of Science. My name's Dan and I'm the editor of Science and Nature,

the monthly magazine from the team behind the week junior. And I'm Michael, the acting deputy editor.

And I'm Jenny, the features editor. On this podcast, we explore the strange phenomena and bizarre events

that have left scientists scratching their heads.

And despite their best efforts, remain well and truly unsolved.

We're on a mid-season break right now, but we thought we'd give you all a little Christmas present.

Yeah, this is a bonus episode of Mysteries of Science, where we look back at some of our favourite moments from 2023.

And play some unheard snippets from our expert interviews. This is Mysteries of Science. This is mysteries of science. This is mysteries of science.

I remember back in 2023, way back then, it's still 2023 now, way back in January 2020.

That's right, where we spoke to Yuval Noah Harari.

I was really impressed we managed to get him on the podcast. Thanks to you, Michael.

And we talked to him about his new book, Unstoppable Us.

And he told us why it's perfectly normal to be scared of monsters under the bed.

Well, Unstoppable Us tells the story of all of us, of human beings, how we came to rule the world. And I wanted to write about this

for young people to help them understand the world and to also help them understand themselves.

You know, many people think that history is about things that happened a long time ago,

but actually it's about what is happening to us

every day and every night.

You know, if you wake up in the middle of the night,

afraid that there is a monster under the bed,

this is actually history.

This is actually a historical memory
