Brian Jones, Jimi Hendrix, Janis Joplin and Jim Morrison all died at the age of 27 between 1969 and 1971. At the time, the coincidence gave rise to some comment, but it was not until the death of Kurt Cobain, about two and a half decades later, that the idea of a '27 Club' began to catch on in public perception, reignited with the death of Amy Winehouse in 2011.
Through interviews with people who knew them, such as music stars, critics, medical experts and unseen footage, the lives, music, and artistry of those who died at 27 are investigated with a bid to find answers.

The search for extraterrestrial life is an age-old quest. But recent breakthroughs make today an era like no other in the history of astronomy. From the exhilarating probing of our own solar system and the Kepler mission’s astounding discovery of thousands of extrasolar planets, to the next-generation telescopes under development, the prospects for finding life beyond Earth have never been stronger.
Still, daunting hurdles remain. How can we study anything light years away, let alone a little planet? In the vast universe, where should we even start to look? Is our failure to hear any other voices in the galaxy a sign that we are special? Join leading explorers now searching the galaxy for life and intelligence on other planets—and asks, if we do find other life in the universe... what would that mean?

Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches... the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence?
The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. The documentary looks at how far we’ve come and where machines are headed as their software becomes ever more... cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?

We humans often like to think we're the end of the line when it comes to evolution. But if we rewind through our short time on Earth as a species, and the many changes that have occurred to us along the way, we find we're still very much a work in progress. Renowned geneticist and author Spencer Wells reveals how changes in our genetic code have fuelled major changes in our appearance and capabilities over time, and why scientists believe we're continuing to rapidly evolve today. By understanding these changes, we are better prepared for the future.

Bitcoin is the world's leading virtual currency, but unlike real money, it is not backed by a government or properly regulated. Bitcoin is exchanged and held digitally by users - which is attractive to criminals selling drugs, pornography and arms. But now Bitcoin is moving into the mainstream and being openly marketed as an investment opportunity. The film investigates what Bitcoin is and what it means, going inside a Bitcoin mine in Iceland - where currency is made - and spending time with the Bitcoin millionaires of Silicon Valley.
The programme also hears from others who have been scammed out of their life savings and investors who think the cryptocurrency is an enormous scam and that the writing is on the wall. Around the world, authorities are sounding the alarm that Bitcoin is too risky - is it too late, or too crazy, to try to become a Bitcoin millionaire?
