Why the search for life on Mars is far from over

Instant Genius ·

2026/07/26

Way back in 1976, NASA’s Viking landers touched down on Mars to search for potential signs of microbial life that could currently exist on the planet’s surface. Despite the mission making a number of promising discoveries, so far, no further landers have returned to the surface of the Red Planet with the aim of repeating these fascinating experiments. As such, many questions still remain as to what organisms, if any, could potentially be living within the Martian soil.In this episode, we’re joined

2026/07/23

Every single day of our lives, we’re exposed to a vast multitude of experiences and interactions with the various people, objects and technologies in the wider world that surrounds us. The chances are that many of us give these moment-to-moment encounters very little thought. But could it be that our desire for convenience, efficiency and productivity has resulted in a widening rift that has ultimately disconnected us from many of the simple pleasures that life can provide?In this episode, we’re

2026/07/19

While largely viewed as a toxic waste product with no practical use, our urine is actually rich in all manner of valuable nutrients that, with a little effort, can be extracted, recycled and converted into fertiliser for use on food crops, used to make building materials or even used to generate electricity. In this episode, we’re joined by Kai Udert, a researcher based at the Swiss Federal Institute for Aquatic Science and Technology, to talk about the many ways we could be putting our pee to

2026/07/16

It’s clear to all of us that the rapid progress that technology has made over the last century or so has had profound impacts on almost every aspect of our lives. But often, the impact on our emotional well-being associated with these great changes is overlooked, or, if mentioned at all, portrayed in a largely negative light. Why is this? Is it simply down to our innate fear of the new or our natural tendency to see the downsides that accompany change? Could it be the case that this mode of thinking

The birth, evolution and future of microchips

2026/07/12

It’s a good bet that if most of us were to glance around our living rooms or offices, we’d quickly spot all manner of electronic devices that are powered by microchips. Since their introduction in the 1950s, chips have become one of the fundamental building blocks of the various digital technologies we rely on in our daily lives. What impact has this had on the development of technology, economics and global politics over the last several decades, and what roles will chips continue to play in our

2026/07/09

For most of us, music has a unique, almost supernatural, ability to trigger our emotions and memories and conjure up evocative images or even fantasies in our minds in a way that few other experiences or art forms can. But what exactly is happening in our brains when we listen to music, is there such a thing as a common musical experience that’s shared by people from different cultures and backgrounds, and can we use any of these powerful effects to help bolster our health and wellbeing?

Why the liver is the body’s most misunderstood organ

Instant Genius ·

2026/07/05

Most of us think about the liver as simply being the body’s filtration system that acts as a sponge that removes toxins from our bloodstreams. But the truth is it performs many more functions that are vital for our health such as acting as the primary organ in regulating our metabolisms, storing essential nutrients our bodies can draw from in times of need, and even producing proteins that help our blood to clot when we’re injured. However, changes in our lifestyles over the past several decades are

Despite affecting as many as 80 per cent of women by the age of 50, fibroids, lumps of tissue that grow in or around the womb, are not commonly discussed outside of specialist doctors’ offices. However, they can cause a whole host of health issues, such as heavy or painful periods, poor bladder control, chronic constipation, and even affect fertility and complicate childbirth.

The miraculous healing ability of our brains

Instant Genius ·

2026/06/28

It was previously thought that once our brains suffer an injury due to stroke or trauma, the potential for recovery was severely limited. But recent developments in medicine have proven that this isn’t the case; our brains are, in fact, capable of miraculous acts of healing. This is thanks to a process known as neuroplasticity, a concept that’s changing the way that medical practitioners are helping patients suffering from brain injuries regain their health.

2026/06/25

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.

How to keep your body younger for longer

2026/06/21

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

2026/06/18

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

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

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

What happens in our bodies when our hormones misfire

Instant Genius ·

2026/06/07

Every minute of every day, our bodies are flooded with a complex web of hormones – chemical messengers that travel through the bloodstream, coordinating everything from our blood pressure, body temperature, metabolic rate and even our emotions. When this system is functioning correctly, we barely notice its actions, but if it begins to misfire, it can lead to profound issues in everything from fluctuations in our energy levels or moods to the way our bodies develop as we age and even our

Becoming a parent is undoubtedly one of the biggest events that can occur in any of our lifetimes – suddenly we have a tiny living being to take care of that demands the majority of our thoughts, time and attention. Of course, this can at times feel overwhelming and often leads us to look for help and advice from our parents, grandparents or close friends. But what strategies do parents in the animal kingdom use to raise their young, and is there anything we humans can learn from them?As part of

Whether it’s the swab tests many of us use to help us piece together our family trees, the painstaking detective work carried out by forensic scientists, or its use in medical screening to look for signs of our predisposition to develop certain diseases, DNA science has become a regular fixture in news stories, pop culture and dinner table conversations in many of our homes.

Why ecoacoustics is the future of conservation

2026/05/24

Traditionally, ecologists wanting to take stock of the diversity, health and population levels of animal species within a given environment have needed to tie on their boots, get out in the field and painstakingly record what they are able to observe manually. But the emerging field of ecoacoustics – the use of sound recording to survey the biodiversity within ecosystems – is promising to be a game-changer in the way researchers are able to approach this work.As part of our Science of Sound
