For many of us, maths is simply a subject we studied at school to help us learn how to count, add one thing to another, and carry out everyday tasks such as managing our personal finances. But if we look more deeply, maths has underpinned the way that humans understand and interpret the world for thousands of years. Without our knowledge of maths, we’d have no smartphones and no internet, our buildings wouldn’t stay sta...

For those of us who live in towns and cities, bogs may seem to be a rare environmental relic left over from times gone by, or perhaps something we’ve only encountered onscreen in spooky fantasy movies. The fact is that these peat-rich, often otherworldly landscapes are found in almost every corner of the globe, have had a deep influence on the development of human culture, and act as one of the planet’s unsung heroes in...

From the neatly curated English country garden to the wild jungles of the Amazon, the Earth is host to a staggeringly diverse range of plant life. One of the key reasons for the great evolutionary success of plants is the wide-ranging versatility and utility of the leaves that grow on them. In this episode we’re joined by Prof Jonathan Silvertown, an evolutionary ecologist based at the University of Edinburgh, to talk about ...

Every built environment we spend our time in, our homes, offices, music venues or sports stadiums – is designed and constructed after hours of consideration about form and function. Oftentimes, less consideration is given to the impact this has on the health of the planet. In this episode, we’re joined by Will Arnold, an environmentalist, engineer, and author, to talk about his latest book, Future Build – How Con...

A late summer sunset, a peaceful, verdant forest, or a Shakespearean sonnet – these are all things that move us emotionally thanks to what we perceive as their beauty. But why is this so, why do environments, art, music, and even ideas move us so emotionally? In this episode, we’re joined by Prof Nicholas Humphrey, an evolutionary psychologist and author, to talk about his latest book, Why Is the World So Beautiful? Ou...

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 asp...

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...

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 t...

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...

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 Pr...

Often in life, we find ourselves being accused of being lazy or accusing others of acting lazily, or maybe even becoming frustrated by what we see as laziness in our own actions. But what do we really mean by the term laziness, why is it viewed as a taboo that transcends cultures, and what effect does considering ourselves or others lazy have on our mental health? In this episode, we’re joined by Prof Katrien Devolder, an et...

No matter how gently or politely we live our lives, at one point or another, it’s inevitable that we’ll find ourselves in a situation in which we disagree with another person and find ourselves having to defend our opinion or perspective. For many of us, these situations are hugely uncomfortable, perceived as destructive, and are to be avoided at almost all costs. Why is this, could interpersonal conflicts actually be u...

When we know a certain fact about the world or hold a certain belief how do we know that others also know this, how do we base our thoughts and actions on our knowledge of what we assume others know, and what impact does this have on the way that society as a whole functions?

When most of us think about time our minds likely turn to thoughts of the second hand that ticks around a clock, or maybe the occasions we’ve been late to catch a bus. But if we stop to think about what time actually is things quickly get more subtle and complicated. Does time only exist in our minds as a psychological illusion, does it really only run forwards and not backwards, and how close is modern physics to helping us ...

Whenever a crime is committed, tiny traces of evidence are left behind at the scene, which, if pieced together correctly, can tell us exactly what happened, when it happened and who was responsible. This is the job of forensic scientists. But how exactly does this process work, how accurate are the portrayals of crime scene investigators we see on film and TV, and what happens if when mistakes are made? In this episode we’re...

Every several years, the surface temperatures of the Pacific Ocean rise, triggering a climate event that has a domino effect on weather patterns across the globe. This is known as El Niño – and this year, meteorologists predict we’re in for a big one. But how exactly do these events occur, how big an effect is climate change having on their frequency and impact, and what can we expect to see in the future? In this epis...

Though we’re often not aware of it, the ground beneath our feet is teeming with an abundance of life and activity – from the complex networks of fungi and tangled roots put down deep into the Earth by the plants that live on its surface to the staggering variety of organisms that make their homes in the damp and darkness of the soil.

It’s widely documented that during the time of the Third Reich, the Nazi Party employed a legion of scientists to aid them in their goals of military superiority and ethnic cleansing – particularly in their pursuit of eugenics and development of cruel nerve agents and chemical weapons.
