This week, the Soviet Internet that never was.

Why with all the motivations, means and mathematics to be able to build a computer network,

do the Soviet scientists stumble so badly?

And a year after a huge earthquake hit Nepal, the threat of landslides means it's still not safe.

What happens after the quake is just as important as what happens during the shaking.

Plus, locating where words live in the brain. This is the nature podcast for April

28, 2016. I'm Adam Levy. And I'm Kerry Smith.

Now, Charmany Bandell has become a bit brain obsessed this week. No, she's not turning into a zombie. She's been learning about language and where we

keep all the words in our heads. The internet is full of ways to procrastinate, and this week I have found a new one.

It's an online 3D model of a brain that Alexander Huth at the University of California, Berkeley, sent to me.

It's interactive, brightly coloured, and you can zoom around and click on different parts to make colourful words pop up.

A perfect distraction.

But it is actually serious science too.

I called Alexander to find out how his team came up with it and what it all means.

We wanted to map how the meaning of language is represented in the brain.

So we took subjects, we put them in an MRI scanner,

and we scanned their brains while they listen to hours of natural stories.

So we're recording essentially blood flow at different points in their brain.

And then we can use that to map out which parts of the brain seem to represent different

concepts or different types of words.

And that's how you've ended up with this beautiful model that I've been playing with all

week. You can click on different bits and see different words, but what did it actually show you?
