Mark Evans joins the bio-prospectors in Central America exploring the untapped reserves of the oceans for life-changing drugs; Aarathi Prasad meets the remarkable old people who could hold the secret to a long and healthy life; and Robert Winston explores how our behaviour and environment may be influencing the genes of future generations in ways we once thought impossible.

Astronaut and neurologist Roberta Bondar explores the new science of heart regeneration - scientists in Dallas have discovered that baby mice can repair their own hearts; could this work for humans too?

And Richard Dawkins and Aarathi Prasad celebrate the achievements of synthetic biology and the work of one man who has learned how to get E. Coli to produce oil.

From the shores of the Pacific to the ice storms of Canada, the programme explores how scientists are using the secrets of our cells to change life as we know it.
