Gut Feeling

Following the release of his book on the gut, Dr Michael Mosley returns to Insight for a discussion with fellow experts and ordinary Australians about how the gut can play an integral role in our overall physical and mental health.Increasingly, research is shedding light on the previously mysterious world of the gut and the 1-2 kilograms of microbes that live there, forming each person's unique microbiome , the genetic ecosystem of bacteria, viruses, fungi and other organisms that lives inside and on our bodies from birth. This week's Insight tackles the ground-breaking science and personal stories around the gut's potential to change our lives.

10 Things You Need to Know about the Future

Horizon looks at the issues that will change the way we live our lives in the future. Rather than relying on the minds of science fiction writers, mathematician Hannah Fry delves into the data we have today to provide an evidence-based vision of tomorrow. With the help of the BBC's science experts - and a few surprise guests - Hannah investigates the questions the British public want answered about the future. Hannah tries to discover whether we could ever live forever or if there will ever be a cure for cancer. She finds out how research into the human brain may one day help with mental health, and if it is possible to ever ditch fossil fuels. Hannah and her guests also discover the future of transport - and when, if ever, we really will see flying cars. She discovers whether a robot will take your job or if, as some believe, we will all one day actually become cyborgs. The programme predicts what the weather will be like and discovers if we are on the verge of another mass extinction. Hannah's tenth prediction is something she - and Horizon - are confident will definitely happen, and that is to expect the unexpected!

Nature's Candy

Episode 4 – reveals the surprising impact sugar can have on our health. The added sugars in most packaged foods are one of the deadliest ingredients in our modern diet. But the naturally-occurring sugars, antioxidants and nutrients found in most fruits and berries make these sweet treats some of the healthiest foods on our planet.

Episode 3 – spotlights some of nature's tiniest packages that deliver a powerful protein punch. Protein is an essential component of our diet, and for centuries, products of animal origin were thought to be one of the best sources. But, new evidence proves diets high in beans are one of the most important dietary predictors of survival for older people around the world.

The Mystery of Dark Energy

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up. The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics. The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge - someone who can write a new theory explaining the mystery of the dark energy.

The Secret Rules of Modern Living: Algorithms

Without us noticing, modern life has been taken over. Algorithms run everything from search engines on the internet to satnavs and credit card data security - they even help us travel the world, find love and save lives. Professor Marcus du Sautoy demystifies the hidden world of algorithms. By showing us some of the algorithms most essential to our lives, he reveals where these 2,000-year-old problem solvers came from, how they work, what they have achieved and how they are now so advanced they can even programme themselves.

Decoding the Brain

After millennia of speculation about what goes on inside the human brain, we now have the tools to explore its hidden reaches. These tools are leading to research that may help those suffering from afflictions such as epilepsy and Alzheimer's disease. They are also shedding light on the mystery of consciousness and what makes us who we are.

Are We Alone

Brian Cox explores the ingredients needed for an intelligent civilisation to evolve in the universe - the need for a benign star, for a habitable planet, for life to spontaneously arise on such a planet and the time required for intelligent life to evolve and build a civilisation. Brian weighs the evidence and arrives at his own provocative answer to the puzzle of our apparent solitude.

The Lost Tribes of Humanity

Alice Roberts explores the latest discoveries in the study of human origins, revealing the transformation that has been brought about in this field by genetics. Traditional paleo-anthropology, based on fossils, is being transformed by advanced genome sequencing techniques. We now know that there were at least four other distinct species of human on the planet at the same time as us - some of them identified from astonishingly well-preserved DNA extracted from 50,000-year-old bones, others hinted at by archaic sections of DNA hidden in our modern genome. What's more, we now know that our ancestors met and interacted with these other humans, in ways that still have ramifications today. Alice uses these revelations to update our picture of the human family tree.

How to Find Love Online

Dr Xand Van Tulleken is single and looking for love. Mathematician Dr Hannah Fry wants to use him as her guinea pig to test whether the algorithms that dating sites use to match people actually work. While Hannah builds a dating site, Xand meets the scientists investigating online dating - and learns what pictures to use and what to write in his profile. He tries out a 'bot' that has automated a swiping app and has an MRI scan to find out whether his brain is equipped for love. 50 members of the public take part in some mini experiments at a date night - and Xand goes on various dates to test whether the algorithm is better than him choosing randomly.
