From design to execution, engineers only had a year to complete the world's largest solar power plant but between the worst monsoon season in over 100 years and a partial solar eclipse this task might be harder than they ever imagined.

Rob Bell uncovers the pioneering history of the London Underground - with special access to its hidden workings, and meeting the staff who know and love it. He explores the construction of the world's first deep Tube line - known today as the Northern Line. The Northern Line runs for 60km through London, connecting north and south across the Thames and 700,000 passengers rely on it every day. But to build it, its Victorian engineers had to overcome unbelievable obstacles. One man, James Greathead, pioneered a new kind of tunnelling machine, that allowed deep tunnels to be built faster and more safely than ever before. But the new Tube line needed newfangled electric trains, lifts and escalators to make it work too. Rob discovers the remains of the first-ever station on the Northern Line, King William Street, just before it is sealed up forever. He gets down on the tracks with the maintenance team at Camden Junction, who toil on this Spaghetti Junction of the Tube every night to keep it working, and opens the sealed tunnels of an abandoned extension of the line in north London. And he meets the station manager at Balham to hear the story of how one of the worst tragedies on the Tube unfolded during the Blitz. Finally he's allowed into the latest tunnelling work, as the Northern Line is extended to Battersea Power Station - where the oldest deep Tube in the world is becoming the newest.

We all know who invented the telephone, the light bulb and the airplane. But what about the computer? This is the story of John Atanasoff, and how in 1937 he unleashed the digital revolution. A story of deceit, greed, academic fraud and perhaps even murder as we try to piece together the origins of the computer and how its creator was denied his rightful place in history.

Spring is in the air and it's the season for sex. In the coastal rainforests, rising humidity kick-starts life in the undergrowth, while out on the water, the rising water temperature is priming the reef for reproduction.

Like many, Michael Mosley wants to get fitter and healthier but can't face hours on the treadmill or trips to the gym. Help may be at hand. He uncovers the surprising new research which suggests many of us could benefit from just three minutes of high intensity exercise a week. He discovers the hidden power of simple activities like walking and fidgeting, and finds out why some of us don't respond to exercise at all. Using himself as a guinea pig, Michael uncovers the surprising new research about exercise that has the power to make us all live longer and healthier lives.

It's summer in North Queensland - the time when the tropics heave with energy and runoff from rainforests pumps nutrients into this supercharged marine ecosystem. Large predators such as sailfish come in from all over the Pacific to feed in the waters. The attack then comes from the sky, where a flock of hungry seabirds wait for their opportunity to strike.

Time gives rhythm to the world around us. But how do we really know what time it is? Professor Brian Cox goes in search of the answer to a question you wouldn't give a passing thought. From our historical dictator of time - the Sun - to the world's irregular flutters and the physical definition of a second by an atomic clock, Brian discovers telling the time is a tricky business. But why do we need to know what time it is so very accurately? Without correct time signals, aircraft, telecommunications systems, the world's global financial systems, global positioning and many other systems we use and rely on everyday wouldn't work. They all depend on knowing the time. Exactly. In this entertaining film, Brian pushes our understanding of time to the depths of our imagination.

Michael Mosley and the doctors undertake the most ambitious experiment yet of the series - testing whether the spice turmeric could help protect us against cancer, with the help of nearly 100 volunteers, several UK universities and some brand-new technology. Gabriel Weston learns how one of these methods, based on a new understanding of the very beginnings of cancer, could soon provide us all with personalised cancer tests. Chris van Tulleken investigates whether glucosamine pills really help with joint pain, and Saleyha Ahsan looks at whether cheap painkillers are as good as expensive brands. Guest Zoe Williams, meanwhile, tries out home cholesterol test kits.

One of the world's top wildlife photographers, Cyril Ruoso, is partnered up with a scientific journalist for an adventurous journey through three of the most extreme ecosystems on our planet, the impenetrable rainforest of the Amazon, the skyscraping glaciers of the Andes, and the desert plains of the Pacific Coast of Peru. During their search for rare and uncommon species, they meet with scientists and discover what links all three ecosystems together. Finally, they understand the need to preserve them when climate change and human activity are threatening their very existence.
