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.

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 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.

When most of us hear "scientific research", it conjures the image of serious men and women in meticulous labs using carefully prescribed methods to achieve rather predictable outcomes. We have an expectation that science is calculated and controlled. Yet some of the most influential scientific discoveries have been made entirely by accident. Does chance work alone or are other phenomenons at play? Combining dramatic re-creation with cheeky animation and cleverly manipulated archival images, Gone Sideways illustrates three areas of exploration: medicine, technology and natural science.

How can many stupid things combine to form smart things? How can proteins become living cells? How become lots of ants a colony? What is emergence?
In a Nutshell • 2017 • Science
A breakthrough called CRISPR opens the door to curing diseases, reshaping the biosphere, and designing our own children. A provocative exploration of its far-reaching implications, through the eyes of the scientists who discovered it.

They're cute, they're lovable, and judging by the 26 billion views on over 2 million YouTube videos of them, one thing is certain: cats are very entertaining. But their strange feline behaviors, both amusing and baffling, leave many of us asking: Why do cats do that? Tony Buffington explains the science behind some of your cat's strangest behaviors.
