A two-hour special from the producers of "Making Stuff" Where do nature's building blocks, called the elements, come from? They're the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. To unlock their secrets, David Pogue, technology columnist and lively host of Nova’s popular "Making Stuff" series, spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe's most abundant elements, and the rarest of the rare—substances cooked up in atom smashers that flicker into existence for only fractions of a second.

Professor Sue Black is joined by Silent Witness's Emilia Fox to reveal the secrets of forensic science. Sue shows how the stories of our lives are hidden in the very fabric of our bodies by examining an archaeological skeleton, using techniques she uses in modern-day forensic investigations. She gradually builds up its identity until a pile of old bones once again becomes a real person. She explains how extraordinary clues in our bones can reveal everything from our age and our sex to our diets and our ancestry – there's even a bone in our ear that can reveal where our mother lived while she was pregnant. Professor Black's investigations into the trauma marks visible in the 1,000-year-old skeleton's bones reveal where this person died, and how they died. In the process, she tells this individual's extraordinary life story and sheds light on one of the darkest days in English history. The Christmas Lectures date back to 1825 when Michael Faraday founded the lectures for children at the Royal Institution. They are the world's longest running science television series, which today use demonstrations and interactive experiments with the live theatre audience.
