One in three of us will get cancer at some stage in our lives. From the moment of diagnosis the common cry is "why me?" Now, across the planet, a select group of scientists is hunting cancer-causing infections. Startling new evidence is revealing that viruses and bacteria are triggering some of the biggest killers of our time. And, believe it or not, this is good news.

Astonishingly, science has uncovered the key to unlimited life – and a secret of endless youth. Deep in the DNA of a humble pond creature an Australian-born scientist co-discovered an 'immortalising' enzyme, a chemical catalyst that can keep cells young, forever. In 2009 this discovery was awarded the Nobel Prize for Medicine. But, this is no simple 'cure' for ageing. For the same enzyme that fuels endless youth, also fuels cancer. Immortal reveals the inner workings of this biological paradox and its remarkable impact on ageing, stress, disease and cancer.
