Whenever we buy a new product or use a service, we simply expect it to work as advertised, usually without giving much thought to how it came to being in the first place. However, behind the scenes, every piece of technology we use, be it a toaster, a lawnmower or even the aeroplane we travel in when we head off on our holidays, has gone through a rigorous series of tests to ensure its safety and efficacy. This often-overlooked aspect of our everyday existence is carried out by test engineers.

In this episode we’re joined by tech journalist and author Alex Davies to talk about his latest book, How to Keep a Plane in the Sky – Tales from the Wild, Unseen World of Test Engineering.

He tells us how engineers design the products we rely on to perform well beyond any expected limits of use, how they build in safeguards to account for almost every eventuality and the great lengths they go to to account for human unpredictability.

Currently, around one in ten of us are living with asthma. For many, the symptoms can be relatively mild, but for others, attacks can be severe, debilitating, and even life-threatening. For the most part, we’ve relied on the same method of treatment to manage the condition for the last few decades. However, new research is showing great promise in helping those who suffer from this often-overlooked condition.

In this episode, we’re joined by Dr Samantha Walker, director of research at Asthma + Lung UK.

She tells us how asthma occurs in several different forms, why we still have so much to learn about the root causes of asthma, and how new technology can help us to treat this often-misunderstood condition more effectively.

These days, supermarket shelves are filled with thousands of different products all vying for our attention; the options are almost endless. However, if we look back in time, we find that our early ancestors simply ate what they were able to hunt and gather and eventually farm. Thanks to the huge number of options we now have available, many of us choose to follow diet plans of various kinds, be it veganism, low-fat, low-carb, or the paleo diet, but what can we learn from evolutionary history about what we should really be eating if we want to live longer, healthier lives?

In this episode we’re joined by Prof Daniel Lieberman, an author and evolutionary biologist based at Harvard University, to talk about his latest book, Fed Up – What Evolution Reveals about Food, Diet and Eating Well.

He tells us why many of us find it so difficult to eliminate certain foodstuffs from our diets over the long-term, how humans evolved to store more body fat than other mammals, and why the good news is that humans are perhaps nature’s ultimate omnivores.

Though often thought of as the poor cousin to our other senses, our sense of smell has played a key role in human life since its very beginnings. It helps us to determine whether certain foods are safe to eat, protects us from environmental dangers such as fire, mould and toxic chemicals, and has even been weaponised for use as a form of racial or economic discrimination. Without it, the world would be a vastly different place.

In this episode we’re joined by Dr William Tullett, an historian and author based at the University of York, to talk about his new book, Sniff – A History of Smells.

He tells us how advances in technology over the last several centuries have resulted in significant impacts on the odours that pervade our everyday lives, how many of us would rather give up our sense of smell than our phones, and explains how we can all reconnect with our sense of smell to widen our experience of the world we live in.

The possibility that we may be living in a simulation created by a more technologically advanced civilisation has occupied the minds of scientists, philosophers and fiction writers for decades. We may never be able to satisfactorily answer this question, but perhaps the best way of investigating its feasibility is by looking at how we might go about creating a simulation universe ourselves.

In this episode we’re joined by Prof Catherine Heymans, Astronomer Royal for Scotland, who investigates this question in her new book, How to Design a Universe – The Science of Real and Virtual Worlds, the royalties of which will be given to the Royal Observatory Trust, which supports astronomy youth projects across Scotland.

She tells us what our current knowledge tells us about the way that the universe operates, explains why we’d need an enormous amount of computing power to generate a simulation universe, and investigates the question of why we, or a more advanced civilisation, might attempt to do this in the first place.
