Radiolab
Life in a Barrel

little details, little doodles of rock.

Radiolab
Life in a Barrel

They're beautiful things to look at.

The amazing thing about these vents is they mimic the structure of cells in that it's kind of a round space with a wall around it.

Radiolab
Life in a Barrel

And you can think of a cell as a kind of a bag of solution with a membrane around it.

Radiolab
Life in a Barrel

That's making these gases react together to form organic molecules, which are forming inside the pores themselves.

Radiolab

They will form spontaneously in this kind of environment into what we call protocells, a little bit optimistically maybe, but effectively a membrane around a bag of water.

with some stuff inside.

Radiolab
Life in a Barrel

Yes, it's got the right materials and it's got the structure.

Radiolab

And I think that's what's been missing from the chemistry and it's what's missing from the soup and it's what's missing from, you know, delivery of organic molecules from space by panspermia.

Radiolab

It ends up in a soup.

Radiolab

How does that soup form structure?

Radiolab
Life in a Barrel

Well, the earth itself forms the structure for you in the first place in these hydrothermal vents.

there is a beautiful link between the geology of the planet with active volcanic systems and active turnover of the surface of the planet and the bottom of the oceans and the way that living cells work.

Radiolab
Life in a Barrel

a living planet gives rise to living cells, which have the same structure.

Radiolab
Life in a Barrel

Both the planet and the cell is a little bit like a battery.

Radiolab
Life in a Barrel

It's got a positive charge outside, a negative charge inside, a membrane surrounding it.

Radiolab
Life in a Barrel

And they're both like that.

Radiolab
Life in a Barrel

And there's a lovely, lovely sense of continuity that a planet gives rise to living cells.

Radiolab
You and Me and Mr. Self-esteem

That you are a horrible person if you touch yourself, if you engage with anybody else in any kind of sex whatsoever outside of marriage.
