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.How The Light Gets In: https://howthelightgetsin.org/festivals/london Hosted on Acast.

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. To read about subjects like this and much more, visit newscientist.com. Hosted on Acast. See acast.com/privacy for more information.

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.

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?

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. To read about subjects like this and much more, visit newscientist.com. Hosted on Acast.
