    Amorina Kingdon on the grunting, growling and singing world underwater
    Sep 9 2024
    Have you ever heard a haddock knock? What about a cusk eel’s chatter? Sound travels four-and-a-half times faster through water than air and can be heard across huge distances. It’s how whales are able to communicate hundreds of kilometres apart. Yet, for all its wonder, much of the underwater acoustic world remains a mystery to scientists. Although human ears can’t detect most marine sounds, the invention of hydrophones – microphones designed to capture underwater audio – is helping scientists begin to unravel this hidden world. So how does sound move through water? And how do underwater creatures perceive and use sound? Amorina Kingdon’s new book ‘Sing Like Fish’ explores these questions, revealing how marine life depends on ingenious uses of sound to communicate, navigate, and thrive. In this episode, Kingdon and host Christie Taylor explore the fascinating ways fish and other marine animals produce sound, the physics of underwater ears, and how humans are impacting critical underwater soundscapes. Plus, samples of some of the most captivating underwater sounds she’s encountered in her research. To read about subjects like this and much more, visit newscientist.com.

Adolescence is a crucial, yet often misunderstood, phase of life. Adolescent psychologist Lucy Foulkes’s new book ‘Coming of Age: How Adolescence Shapes Us’ will leave you reflecting on your own formative years in a whole new light – and offers insights that may help settle your anxieties as a parent of teens. In this episode, Foulkes explains to New Scientist editor Catherine de Lange why adolescence is often such a challenging period, explains how these struggles are essential for self-discovery and shares tips on how adults can help the young people in their lives navigate this tricky period.

  • Carlo Rovelli on the link between quantum physics and world peace

    Carlo Rovelli on the link between quantum physics and world peace
    Jul 29 2024
    Quantum theory describes the tiny building blocks that make up everything around us. It has made many successful predictions but could a new, more radical idea help us make better sense of the world around us? Could it even be the answer to creating world peace? Carlo Rovelli is an Italian theoretical physicist and writer behind the relational interpretation of quantum mechanics. His idea suggests that the fundamental building blocks of the universe are not particles or objects as many of us are taught in school, but relationships and interactions between them. In this episode, Rovelli explains why he believes we should all be applying his theory to our everyday lives and relationships. And how it could even help improve international relations.

  • The incredible, intelligent abilities of plants with Zoë Schlanger

    The incredible, intelligent abilities of plants with Zoë Schlanger
    Jul 15 2024
    What if we told you plants can hear and see? And memorise information? And track time to adapt their pollination techniques? And even look out for their family members? These are just some of the remarkable behaviours plants are capable of – many of which we’re only just learning about now. Science journalist Zoë Schlanger’s new book The Light Eaters will make you question everything you currently assume about the green life around us, and even what “intelligence” can mean. In this episode, Schlanger walks us through some of the incredible abilities and behaviours plants employ to not only survive, but thrive – from orchids sexually deceiving wasps, to shape-shifting vines that flew under the radar of researchers for decades. And, she suggests, it might be time to rethink how we do science to accommodate the seemingly endless adaptability of plants. To read about subjects like this and much more, visit newscientist.com.

  • Sonifying Mars, symphonically, with David Ibbett

    Sonifying Mars, symphonically, with David Ibbett
    Jul 1 2024
    Despite humans having never set foot on Mars, scientists have been working for decades to paint a picture of life on the red planet. With the help of photos and videos from robotic rovers, scientists now know more than ever about its rocky terrain, early history and current climate. Now, experts are painting a fuller picture of the dusty planet by using audio recordings captured by these rovers. Composer David Ibbett has used that data in epic fashion: to create an immersive concert that harnesses the sounds of Mars and transforms them into musical instruments and melodies. In this episode, Ibbett explains to host Bethan Ackerley how ‘Mars Symphony’ includes the real sounds of Mars’ winds, dust devils and seismic rumbles and takes the audience on an interplanetary journey through the past, present and future of the red planet. Still curious? Attend an upcoming performance or experience the music of Mars from your computer, at MarsSymphony.com. To read about subjects like this and much more, visit newscientist.com.

  • The catastrophic health consequences of racism with Layal Liverpool

    The catastrophic health consequences of racism with Layal Liverpool
    Jun 17 2024
    We like to think of science and medicine as unbiased, unaffected by social constructs. But we see evidence to the contrary everyday, from false yet persistent claims that black people’s bones are denser to the reality that the covid-19 pandemic disproportionately impacted people of colour. In her debut book Systemic: How Racism is Making Us Ill, science journalist Layal Liverpool explores the health consequences of racism. She showcases how fatal stereotypes can leave people of colour in need of medical care undiagnosed, untreated and unsafe. In this episode, Liverpool explains how race and racism infiltrate every aspect of health – from living in polluted areas to being dismissed by doctors in the hospital. She lays out the problematic history of medicine and health science. And she highlights the many ways people are beginning to make meaningful change.

  • On the hunt for alien life with Lisa Kaltenegger

    On the hunt for alien life with Lisa Kaltenegger
    Jun 3 2024
    If (or maybe when) we find alien life in the universe, will it look like us? As telescopes become bigger, our ability to peer into the cosmos is only getting better. So the question may not be “will we find something?” but rather “what exactly should we be looking for?” Lisa Kaltenegger is an astrophysicist and founding director of Cornell University's Carl Sagan Institute. She even works out of Sagan’s old office and shares the same optimism and enthusiasm he brought to the search for extraterrestrial life. Abby Beall speaks to her about her new book Alien Earths: Planet Hunting in the Cosmos, which takes readers on a cosmic adventure to faraway exoplanets with oceans of lava and multiple suns. Through the conversation Lisa explains how Earth’s geological history can help inform our search for life, while acknowledging alien life may not look the same as us. She discusses the technology that has allowed us to enter a new epoch of exploration – and what technological advancements are needed to help advance our search for alien life. And she examines the alien worlds that feature in various science fiction worlds, like those in Star Wars and Avatar, and whether they could actually exist somewhere in the universe.
