Ah, Benny's parents, thanks for coming.

Hiya.

So, Benny has really blossomed this term.

You're telling me, he outgrew his bike. We sold it, on eBay.

Oh, that's not quite what I meant.

It's free to sell on there.

Free to sell?

Easy too. Sold Benny's bike, your guitar, my jacket.

You sold my guitar?

Shall we talk about Benny?

When it's this easy to sell for free, you can't help but say when it's eBay.

Things people love.

T's and Cs apply, exclusive vehicles.

Another thing about E. coli is that to understand what it means for it to be alive is to understand how it's alive with other E. coli.

For a long time, scientists just thought about E. coli just as this little chemical factory.

You just feed it and it grows and it replicates and it grows and it replicates and you look at the proteins that it uses to do all that, and that's it. But if you actually look at all the genes in

E. coli, a lot of them have nothing to do with that kind of process. They, for example, have

genes to make signals that they can send to other E. coli, in a sense, talk to each other,

and they use the information that they get from each

other to make group decisions. So, for example, when the E. coli come into your body and settle down,

they might start talking to each other and, as a group, decide to make something called a biofilm.

So what they do is they switch on a bunch of genes to make this weird kind of glue substance.
