After we've printed out toys for all the kids, it's time to ask an important question: why is Google building a robot army? Or at least, why is it buying up so many robotics companies?

Next, we go 10 floors up in the world's most futuristic building material... wood. Seriously, wood, done right is superior to concrete, steel, almost anything. Find out how in our huge feature.

We also examine the science of sleep - everyone does it for as much as a third of their life, but are too many people in West now doing it wrong? How much value should we put on a good night's sleep anyway?

And if that's not enough, we have a massively in-depth feature on plastic. Just plastic. Well, not just plastic - specifically what the hell we're going to do about all the plastic, and can't we recycle the stuff more effectively because after all, old plastic is essentially the same as new plastic. That's the problem. One man thinks he might have the answer, though.

Plus Peugeot's new air-powered car, the future of inflatable technology, and ultralight Chromebooks and computer glasses that aren't the Google ones - reviewed and ranked!
