When most of us think of parasites, our minds will likely turn to thoughts of the various icky creatures that can invade our bodies, make their homes there and end up making us ill. But the truth is that parasites make up a hugely significant part of all life on Earth and bring many benefits to the organisms they live in or alongside and the wider ecosystems they are a part of.

As part of the Nature’s Unsung Heroes miniseries, we’re joined by Timothy Brown, a researcher based at the University of Leeds and member of the IUCN Parasite Specialist Group who works on the conservation of parasite diversity, to talk about the many ways in which parasites influence life on Earth.

He tells us how our own bodies are host to trillions of different beneficial organisms, the key role parasites play in managing the balance of the animal life in the ecosystems they are part of and talks us through the most recent ideas researchers are working on to preserve these overlooked, but ecologically vital creatures.

When it comes to the effects of ageing on our bodies, there are many more factors at play than simply the number of years we’ve been alive. It turns out, that for some people, there is a huge gap between their chronological age and their biological age – the scientific measure of how well our cells, tissues and organs are functioning compared to the global average. But what are the main drivers of this difference, and what can we do to keep our bodies younger and healthier for longer?

In this episode, we’re joined by ageing and longevity expert and research director at Inserm in France, Jean-Marc Lemaitre to talk about his latest book, Choose Your Age – Unlocking the Cellular Science of Longevity.

He talks us through the many factors that lead to some of us ageing more quickly than others, tells us what researchers can learn from how the world’s centenarians live their lives, and explains why we still don’t know what the limit for the human lifespan could be.

The truth is, when most of us think of wasps, our minds will likely go to memories of irritating winged pests landing in our drinks when we’re trying to have a nice summer picnic or perhaps one of the times we got a nasty sting when we were out playing in the park as children. It’s fair to say wasps have a pretty bad rap. But if we look more closely, it soon becomes clear that most of us are getting these fascinating insects entirely wrong.

As part of our Nature’s Unsung Heroes miniseries, we’re joined by BBC broadcaster, author and entomologist based at the University of Gloucestershire Prof Adam Hart to talk about the many benefits wasps bring to the ecosystems they live in.

He tells us how wasps act as the wardens or guardians of our gardens and agricultural land by keeping pests under control, how they act as essential pollinators that help the ecosystems they live in thrive, and how they act as one of the natural world’s most sophisticated architects and engineers.

These days the supplement industry is booming – supermarket shelves are stacked high with all manner of pills and powders claiming to do everything from helping us to live longer or improving our digestive health to boosting our energy levels or even improving our ability to concentrate and focus. How have we reached this point, why do many of us feel our diets aren’t giving us everything we need to stay healthy and productive, and do these supplements live up to the bold claims that many manufacturers make for them?

In this episode, we’re joined by dietician and author Josie Porter to talk about her latest book, How Not to Take Supplements – A Dietician’s Guide to Thriving on Real Food.

She tells us how our busy lifestyles are leading more of us to turn to dietary supplements, talks us through the rise in the consumption of protein powders and meal replacement drinks, and explains how, underlying health conditions aside, we can all get everything our bodies need to stay healthy by eating a balanced diet.

Although it often goes unnoticed, plankton is the most abundant form of life in Earth’s oceans, making up 95 per cent of all oceanic biomass. These tiny organisms are responsible for generating around half of the planet’s oxygen, play a vital role in the oceans’ food chains and were around for millions of years before we humans came onto the scene. Simply put, without plankton, the world would be a very different place.

As part of our Nature's Unsung Heroes miniseries, we’re joined by senior advisor to the United Nations on oceans Vincent Doumeizel to talk about his latest book, The Power of Plankton – How Plankton Made Life on Earth Possible and Why It’s Key to Our Future.

He tells us how these often-ignored organisms played an essential part in the evolution of life on Earth, tells us the many ways plankton acts as the caretaker of the entire planet, and makes a passionate case for why we should be paying more attention to these fascinating, ancient organisms.
