In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry's most beautiful intellectual creations - the periodic table.

Just 92 elements made up the world, but the belief that were only four - earth, fire, air and water - persisted until the 19th Century. Professor Al-Khalili retraces the footsteps of the alchemists who first began to question the notion of the elements in their search for the secret of everlasting life. He reveals the red herrings and rivalries which dogged scientific progress, and explores how new approaches to splitting matter brought us both remarkable elements and the new science of chemistry.

In the final part, Professor Al-Khalili uncovers tales of success and heartache in the story of chemists' battle to control and combine the elements, and build our modern world. He reveals the dramatic breakthroughs which harnessed their might to release almost unimaginable power, and he journeys to the centre of modern day alchemy, where scientists are attempting to command the extreme forces of nature and create brand new elements.

In the non-coding 98% of our DNA, we have countless switches to promote or suppress the physiological reactions of our bodies. Interestingly, we can change the states of these switches through our own efforts and even can affect the DNA conditions of our offspring before their birth.

How does altruism begin. Is it biological? Is it taught? Researchers are trying to understand the DNA of altruism by studying toddlers.

The brain was once thought to be the body's control tower, issuing commands to the other organs. But scientists are discovering that communication flows between all the organs in our bodies. They transmit messages that can boost immunity, improve memory, strengthen bones and even lengthen lifespan.
Are we in fact living in a simulation? This is the question postulated, wrestled with, and ultimately argued for in the latest provocation from acclaimed documentary stylist Rodney Ascher (Room 237, The Nightmare) through archival footage, compelling interviews with real people shrouded in digital avatars, and a collection of cases from some of our most iconoclastic figures in contemporary culture.
