Wow! What’s everyone been up to, cos there’s an enormous amount in this month’s issue!
Science & Natural World
We all know that a vast many parrots and parakeets are bright green. But how did they get this way when so few other creatures are so colourful? [Long read]

Talking of green … there’s a lot more to trees than meets the eye: they have a whole underground communications network. [Long read]
And still with green things … the whole world was changed by a glass terrarium that made it possible to successfully transport plants across the globe.

Our body clocks are related to sleep. And sleep is still a mystery to be untangled.
Do you suffer from exploding head syndrome? If so there’s a group of researchers who want to hear from you.

Food & Drink
Delia Smith doesn’t like modern cookery, describing it as “poncey” and “chefy”. For once I agree with her.
