In 50 years from now, cities will be home to 70% of all human beings. They will have seven billion mouths to feed and will face an immense challenge in terms of food supply. Are hydroponics and vertical farming going to solve this challenge?
Megalopolises are spreading out and becoming denser -- and there is nowhere left to park. Luckily, the technology is there to deal with this growing chaos. Technological urbanism promises hyper-rational cities that are 100% sustainable and perfectly safe. They are known as smart cities.

Inhospitable environments that would normally be unreachable become accessible thanks to a new class of robot - Robot Explorers. Robots can help us in difficult tasks like search and rescue operations. Is there any danger in letting machines handle so many tasks that used to belong to us?
Looks at the black market website known as the Silk Road, which emerged on the darknet in 2011. This 'Amazon of illegal drugs' was the brainchild of a mysterious, libertarian intellectual operating under the avatar The Dread Pirate Roberts. Promising its users complete anonymity and total freedom from government regulation or scrutiny, Silk Road became a million-dollar digital drugs cartel. Homeland Security, the DEA, the FBI and even the Secret Service mounted multiple investigations in the largest online manhunt the world had ever seen. But it would be a young tax inspector from the IRS, who had grown up in the projects of Brooklyn, who would finally crack the case and unmask 'DPR'.

Catch a first-time glimpse at smart technology that will put android helpers in the home, network commuters and entire cities to the Web, and bring us entertainment systems that can virtually make dreams come true. Advances in artificial intelligence are creating machines with near human-like mental agility. Intelligence will be embedded everywhere -- even in our clothing, thanks to smaller, more powerful computers.
From the Stone Age to the Silicon Age, materials have helped drive forward our civilisation. By manipulating materials we have been able to transform our world and our lives - and never more so than in the past century when we have discovered and designed more materials than at any other time in human history. (Part 1: Metal) Professor Mark Miodownik travels to Israel to trace the history of our love affair with gleaming, lustrous metal. He learns how we first extracted glinting copper from dull rock and used it to shape our world and reveals how our eternal quest for lighter, stronger metals led us to forge hard, sharp steel from malleable iron and to create complex alloys in order to conquer the skies. He investigates metals at the atomic level to reveal mysterious properties such as why they get stronger when they are hit, and he discovers how metal crystals can be grown to survive inside one of our most extreme environments - the jet engine.
