30 分钟Hello and welcome to another episode of No Such Things a Fish,
a weekly podcast coming to you from the QI offices in Covent Garden.
My name's Anna, I'm here today with Andy, James and fellow QIL, Alice Campbell-Davies.
And once again,
we've gathered around the mics with our four favourite facts from the last seven days and in no particular order here we go,
starting with you, Alice.
So my fact is humans should be able to sense magnetic fields.
Should be.
Should be.
So there's been a little bit of research into this, not that much actually,
but we have cryptochrome in our retinal cells which is what's responsible for pigeons, migration and that kind of thing.
And we also have magnetite in our brains,
which is a magnetic nanoparticle which helps direct other animals like bacteria.
So why the disappointing lack?
Why can't I say where I live from here?
Well, Andy.
You live south, can you point south from here?
Yes, I can actually.
But only because you know where the river is.
I know where the river is.
