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.
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.
Seventy years ago, when the coldest thing in your house was a pantry, most of the food we ate was harvested, sent straight to the shops and would have been on our plates before it started to go off. However, the advent of the home freezer and advances in various preservation techniques changed all of that and now we’re used to eating what we want, when we want, regardless of the time of year when the food is actually grown. So how do they keep the food for so long? And does the quality stay the same?
