Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.

Stay inside all the time? Never take your shoes off? Feel fatigued? You could have Natural Deficit Disorder. Learn how the earth can help neutralize the disease-causing radicals in the body, by doing something as simple as swimming or walking barefoot.

Richard Feynman was a scientific genius with - in his words - a "limited intelligence". This dichotomy is just one of the characteristics that made him a fascinating subject. The Pleasure of Finding Things Out exposes us to many more of these intriguing attributes by featuring an extensive conversation with the acclaimed Nobel Prize winner. During the course of the interview, which was conducted in 1981, Feynman uses the undeniable power of the personal to convey otherwise challenging scientific theories. His colorful and lucid stories make abstract concepts tangible, and his warm presence is sure to inspire interest and awe from even the most reluctant student of science. His insights are profound, but his delivery is anything but dry and ostentatious.

Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.

Dr Helen Czerski delves into the Horizon archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history.

The region of Lake Turkana, located in Kenya and Ethiopia, is considered to be “the Cradle of Humankind”. Among other finds, primate fossils from millions of years ago have been discovered in the region. But what about the region’s modern inhabitants and their relationship to their environment? Iiris Härmä, whose previous work includes the award-winning Leaving Africa, had the chance of joining Helsinki University’s researchers, Álvaro Fernández-Llamazares and Mar Cabeza, on their pre-pandemic trip to study the Daasanach people’s relationship to their environment through traditional animal tales. The researchers hope that storytelling would help to bridge the gap between people’s everyday lives and conservation efforts.

Using engaging interviews and arresting visuals, this documentary investigates the case for milk as a nutritious food. Is milk good for us or not?

From Raymond Baxter live on Tomorrow's World testing a new-fangled bulletproof vest on a nervous inventor to Doctor Who's contemporary spin on the War on Terror, British television and the Great British public have been fascinated with the brave new world offered up by science on TV. Narrated by Robert Webb, this documentary takes a fantastic, incisive and funny voyage through the rich heritage of science TV in the UK, from real science programmes (including The Sky At Night, Horizon, Tomorrow's World, The Ascent of Man) to science-fiction (such as The Quatermass Experiment, Doctor Who, Doomwatch, Blake's 7, The Hitchhiker's Guide to the Galaxy), to find out what it tells us about Britain over the last 60 years.
