What Is Life?

Life is all around us, abundant and diverse. It is truly a marvel. But what does it actually mean to be alive, and how do we decide what is living and what is not?

After a lifetime of studying life, Nobel Prize-winner Sir Paul Nurse, one of the world’s leading scientists, has taken on the challenge of defining it. Written with great personality and charm, his accessible guide takes readers on a journey to discover biology’s five great building blocks, demonstrates how biology has changed and is changing the world, and reveals where research is headed next.

To survive all the challenges that face the human race today - population growth, pandemics, food shortages, climate change - it is vital that we first understand what life is. Never before has the question ‘What is life?’ been answered with such insight, clarity, and humanity, and never at a time more urgent than now.

‘A nearly perfect guide to the wonder and complexity of existence.’ -Bill Bryson
