Why the search for life on Mars is far from over
2w ago00:34:20Tap to summarizeWay 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 by astrobiochemist and author Steven A. Benner to talk about his latest book, Meet the Neighbours – Life on Mars and How to Find it. He talks us through some of the scientific debates surrounding the Viking data that continue to this day, tells us how our knowledge of the evolution of life on Earth informs our search for life elsewhere in the Solar System, and explains how recent innovations in the democratisation of spacecraft technology may reignite our search for life on Mars.

Transcribe →Why rediscovering simple pleasures may be the key to happiness
2w ago00:32:52Tap to summarizeEvery 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 joined by Prof Ian Bogost, a computer science and design researcher based at Washington University and author, to talk about his latest book, The Small Stuff – The Sensory Enchantment of Everyday Life. He tells us why he proposes that our lives have been incrementally dematerialised thanks to the relentless technological drive for efficiency, why we find pleasure and gratification in sensory experiences, and how, by paying more attention to the simple act of doing rather than the final outcome of our actions, we can all live more deeply enriching lives.

Transcribe →Why human urine may be our most untapped natural resource
3w ago00:26:33Tap to summarizeWhile 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 better use. He tells us how our current systems of dealing with wastewater came into being, what happens to our urine once we flush it down the toilet, and talks us through some ways in which we may be able to make more use of this common, overlooked resource.

Transcribe →How new technology can change our emotional lives for the better
3w ago00:29:08Tap to summarizeIt’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 is leading us to miss the many ways in which new technology can help our emotional lives to flourish? In this episode, we’re joined by Pamela Pavliscak, a researcher and author whose work focusses on the intersection of technology and our emotions, to talk about her latest book, All the Feels – How Technology Can Change our Emotional Lives for the Better. She tells us how often the arguments surrounding issues such as screentime and its impact on our emotional lives are lacking in nuance, how the sharing of memes and gifs has given us a new means of expressing our many complicated emotions, and how the advent of AI chatbots is, more than ever, having profound effects on the way we emotionally engage with technology.

Transcribe →The birth, evolution and future of microchips
4w ago00:29:30Tap to summarizeIt’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 global future? In today’s episode, we’re joined by Prof Rakesh Kumar, John Bardeen Faculty Scholar in the Electrical and Computer Engineering Department at the University of Illinois, to talk about his latest book, The Chip Age – How Chips Shaped Our Past and Will Define Our Future. He tells us about the key role the space race played in the rapid development of microchips, explains how the production of chips involves collaboration between countries in almost every part of the world and talks us through some of the various economic, political and environmental issues that may influence the future of this vital technology.

4w ago00:26:11Tap to summarizeFor 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? In this episode, we’re joined by Prof Elizabeth Margulis, director of the Music Cognition Lab at Princeton University, to talk about her latest book, Transported – The Everyday Magic of Musical Daydreams. She tells us how, while we may think of listening to music as a highly subjective experience, there are many universal ways people from all walks of life are affected by it, how researchers are studying this fascinating phenomenon, and how we may be able to harness these deeply human effects to help boost our mental health, wellbeing and even creativity.

Transcribe →Why the liver is the body’s most misunderstood organ
Jul 500:30:36Tap to summarizeMost 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 leading to an alarming rise in the prevalence of damage and disease to this essential organ. In this episode, we’re joined by Dr Quin Wills, a researcher and CEO of the biotech company Ochre Bio, who specialises in developing innovative new treatments to combat liver disease. He talks us through the many functions the liver performs in our bodies, explains some of the most common causes of the rise in chronic liver disease and looks forward to the future to detail some of the cutting-edge treatments that may be on the horizon to combat this growing issue.

Transcribe →Why this common women’s health condition is so misunderstood
Jul 200:42:12Tap to summarizeDespite 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. In this episode, we’re joined by Dr Michelle Griffin, a women's health expert, author and former BBC Science Focus columnist, to talk about her latest book, Fibroids – Everything You Need to Know, From Symptoms to Diagnosis and Beyond. She tells us how the location of fibroids determines the specific symptoms and complications associated with them; the role hormones play in their development and growth and talks us through some of the latest developments in treating this common but overlooked condition.

Transcribe →The miraculous healing ability of our brains
Jun 2800:34:35Tap to summarizeIt 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. In this episode, we’re joined by neurologist and author Orlando Swayne to talk about his latest book, How to Use a Fork – Stories of Mending the Broken Brain. He tells us what happens in our brains following injury, how learning new skills can change the structure of our brains, and how we can use this process to help people recover from strokes, aneurysms and other debilitating brain injuries.

How parasites play a vital role as caretakers of Earth’s ecosystems
Jun 2500:40:50Tap to summarizeWhen 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 our 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.
