Changes to the bacteria that live inside all of us are responsible for increasing the number of people with allergies, suggests new research. The programme investigates this claim by conducting a unique experiment with two allergic families in order to find out just what it is in the modern world that is to blame.
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. Innovative treatments are being developed to harness the power of this hidden network. But what happens when there's a communication breakdown? We look for clues using the latest technology.

But these aren’t just nasty hitch-hikers. Many are crucial to your survival. Evidence suggests that a diverse microbiome can keep you healthy and, conversely, a damaged one could kill you. NOVA Wonders peers into this microscopic world to discover the fascinating, bizarre, and downright surprising secrets of the human microbiome, including the world’s largest stool bank, which transforms raw stool into life-saving poop pills.
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.

When you breathe, you transport oxygen to the body’s cells to keep them working, while also clearing your system of the carbon dioxide that this work generates. How do we accomplish this crucial and complex task without even thinking about it? Emma Bryce takes us into the lungs to investigate how they help keep us alive.
