Hello and welcome to another Working From Home episode of No Such Thing as a Fish,
a weekly podcast coming to you from four undisclosed locations in the UK.
My name is Dan Schreiber, I am sitting here with Andrew Hunter Murray,
James Harkin and Anna Chaginski and once again we have gathered round the microphones with our four favorite facts from the last seven days and in no particular order,
here we go.
Starting this week with my fact, my fact is, sand dunes are brilliant at social distancing.
So they're safe.
Sand dunes are inanimate objects.
Okay so I would suggest that if they're two meters apart they will always remain two meters apart.
Is that as in they're not moving are they?
They, sand dunes do move.
They constantly are traveling through the desert.
They are a body that falls over on itself and and travels.
So yeah sand dunes are constantly shifting and that's why when deserts encroach on places you've got these giant waves of sand dunes that head towards you.
It's like an army but scientists in Cambridge University have sort of simulated,
they've built an experiment whereby they've been able to study the movement of sand dunes and they've discovered
that basically they do communicate with each other in you know inverted commas,
communicate with each other by sending signals to not encroach on their patch so they don't collide.
We still fully don't understand why it is.
I mean it's pretty extraordinary.
