Facebook’s 'like' button is ubiquitous across the web. It’s how user data is collected, meaning adverts and newsfeeds can be targeted more effectively. Some say there’s nothing to worry about, but others point to the Cambridge Analytica scandal, suggesting how Facebook might shape our opinions. But is there something else we should be worried about? Approval from our friends and family can be addictive – so is the pursuit of “likes” on social media the reason we’re glued to our mobile phones? Tim Harford asks how should we manage our compulsions in this brave new online world.

Want a warm and waterproof wetsuit? Then take a look at how the sea otter does it! It’s all down to air-trapping hairs.

The Population Bomb, published by Stanford biologist Paul Ehrlich in 1968, predicted that populations would grow more quickly than food supplies, causing mass starvation. Ehrlich was wrong: food supplies kept pace. And that’s largely due to the years Norman Borlaug spent growing different strains of wheat in Mexico. The 'green revolution' vastly increased yields of wheat, corn and rice. Yet, as Tim Harford describes, worries about overpopulation continue. The world’s population is still growing, and food yields are now increasing more slowly – partly due to environmental problems the green revolution itself made worse. Will new technologies come to the rescue?
