Maybe you have a deep, booming voice. Or perhaps itâs light and mellifluous. Some peopleâs voices are honey-smooth while others are as rough as gravel. But why does your voice sound the way it does? CrowdScience listener Hannah in Berlin is training as a teacher and will be using her voice a lot in the classroom in future. She wants to understand more about it: how can she improve the quality of her voice and protect it? And what factors - physical, genetic and environmental - determine the sound of your voice in the first place?
Together with presenter Marnie Chesterton, Hannah pays a visit to speech tutor Prof Viola Schmidt at the Ernst Busch University for the Performing Arts in Berlin. Viola and actor Aurelius give us a masterclass in just what your voice can do, as they throw words and sounds to each other across the rehearsal room at a dizzying pace. And Viola gives Hannah a few top tips on using her voice clearly and authentically in the classroom.
Hannahâs isnât the only voice-related question in this episode. Peter from the Kingdom of Eswatini thinks people there speak more loudly than in other countries, and wonders why. To answer Peterâs question we turn to Prof Caleb Everett from the University of Miami. The juryâs out on whether people in some countries really do turn up the volume, but Caleb shares evidence of a link between the climate of a particular region and the sound of its native language. And finally, listener Jonathan has an unusual question for Marnie. When listening to CrowdScience, he canât tell whether heâs hearing Marnie or fellow presenter Caroline Steel. This got him wondering whether itâs common for two people to sound very similar. Marnie gives Caroline a call, and together they set out to discover if your voice really is unique to you. Caroline tracks down a forensic speech scientist - Dr Jess Wormald from the University of York in the UK â while Marnie speaks to Dr Melanie Weirich from the Friedrich Schiller University of Jena in Germany. And both experts agree that Jonathan may be onto something!

CrowdScience listeners David and Tatiana have long been captivated by an unusual dinner table discussion: the peculiar change theyâve noticed over the past 16 years in the sunlight streaming through their bedroom window in Ostend, Belgium. Theyâre convinced that the room has not only become sunnier but that the actual angle of sunlight has shifted.
Intrigued by their observations, we head to Ostend. Our mission: to investigate three of their theories, enlisting expert help along the way.
Theory 1 â A celestial anomaly?RenĂ© Oudmaijer at the Royal Observatory of Belgium considers whether our shifting position in the solar system might explain the change.
Theory 2 â Movement in the Earthâs crust?Alejandra Tovar from the Geological Survey of Belgium examines tectonic data to see if the Earthâs crust is moving enough to alter the angle of sunlight.
Theory 3 â Subsidence?Structural engineer Kath Hannigan helps us inspect the building for signs that it may be sinking or twisting.
And we explore one final theory of our own, enlisting memory expert Julia Shaw to examine whether it could all be a trick of the mind.Will the team crack the case?

Fungi are a mysterious and understudied life form. And to add to the intrigue, some of them actually glow in the dark. This phenomenon has sparked CrowdScience listener Derek's curiosity, and he's asked us to investigate.
Presenter Caroline Steel gets on the case. This is just one example of the natural wonder that is bioluminescence â living organisms that glow. How do they produce their light, and is there any reason for it? Caroline visits a bioluminescent bay in Puerto Rico, and Dr Brenda Soler-Figueroa explains what makes it sparkle.
But it turns out there are many different explanations for why living things glow. Fungi, which listener Derek is particularly interested in, are neither plants nor animals, but an entirely different kingdom of life that we know much less about. Professor Katie Field takes on the task of trying to grow us some bioluminescent mushrooms, while Prof Cassius Stevani explains how â and importantly, why â they glow.
And finally â could we ever harness the power of bioluminescence to our advantage in the future?

Can learning new languages make us forget our mother tongue? CrowdScience listener Nakombe in Cameroon is concerned that his first language, Balue, is slipping from his grasp. He has learned multiple languages through his life, but Balue is the language of his family and home. Itâs central to his identity and sense of belonging. So why does it seem to be fading from him, and what can he do to get it back?
We search for answers, investigating what happens in our brains when we struggle to recall languages, as well as the social and economic factors that lead to language loss. Presenter Anand Jagatia asks Michael Anderson from the University of Cambridge, an expert on memory and forgetting, whether forgotten languages disappear from our brain, or just become difficult to access. Linguist Monika Schmid from the University of York takes us through the phenomenon of first language attrition, and has words of reassurance and advice for Nakombe and others in his situation.
And we meet Larry Kimura from the University of Hawaiâi at Hilo, a pioneer of Hawaiian language revitalization, and Gabriela PĂ©rez BĂĄez, an expert in indigenous languages and language revitalization at the University of Oregon. They explain why languages around the world become threatened, and how to keep them alive.

While there is a myriad of deodorants, shower gels and perfumes helping us stay fresh and fragrant today, that hasnât always been the case. How did humans stay clean in the past, or did they not care so much? And is there an evolutionary reason for human body odour in the first place?
These are questions that CrowdScience listener Sarah has pondered on trips in her camper van, when she wants to keep clean, but washing isnât always convenient.
In search of answers, presenter Anand Jagatia delves into the sweaty details: where body odour comes from, why some people's armpits don't smell, and whether this heady stink serves any purpose. Could our natural odour really help to attract a partner, or is it just a smelly bacterial by-product?
Anand explores the intriguing mystery of human pheromones, and hears how for hundreds of years, Europeans were terrified of washing.

2024 is the biggest election year in history. From Taiwan to India, the USA to Ghana, by the end of the year almost half of the worldâs population will have had the chance to choose who governs them. But there are a huge number of possible voting systems â and listener James wants CrowdScience to find out which is the fairest. To do so, we create a fictional country called CrowdLand to try out different electoral systems. Presenter Caroline Steel consults mathematician David McCune and political scientists Eric Linhart and Simon Hix, and we hear from listeners around the world about how they vote in their respective countries. Can we find the perfect voting system for CrowdLand?

With huge heads on top of spindly stalks, how do sunflowers defy gravity to stay standing? That was a question sent to CrowdScience by listener Frank, whose curiosity was piqued by the towering sunflowers on his neighbourâs deck. They stay up not only when the weather is fine, but, even more impressively, during strong winds. Could this feat of strength, flexibility and balance inspire the construction of tall buildings?
It's a question that takes presenter Anand Jagatia to a sunflower festival in England, to see how the sunflowerâs long evolutionary lineage has honed its structure. And from tall flowers to tall buildings, we turn to structural engineers, asking how these concepts factor into the design of the worldâs tallest skyscrapers. Can ideas drawn from sunflowers or other natural structures help buildings withstand wind, or even storm surges?

The Moon and Earth are drifting gradually further apart. Every year the gap between them increases by a few centimetres. We know that the Moonâs gravity has an important effect on Earth - from controlling the tides to affecting the planetâs rotation - but slowly, imperceptibly, over billions of years, that influence will diminish as the Moon moves away. For CrowdScience listener Tony in the UK that idea poses another question. What if we were to look back in time? What effects did the Moon have when it was closer to Earth? Would it counteract the planetâs gravity more so that, at the time of the dinosaurs, a Brontosaurus would weigh a little less that it would if it existed now? Itâs an intriguing question. And, given that it involves both the Moon AND dinosaurs, itâs one thatâs got presenter Anand Jagatia really excited!
Anand begins his journey on Brighton beach on the South coast of the UK. Heâs there to watch the full Moon rise - and get a few insights on Tonyâs question - from astronomer Darren Baskill and astrophotographer (and cellist) Ivana Perenic.
Anand talks to Darren about the influence of the Moonâs gravity on Earth today. As they stand on the beach, with the sea lapping at their feet, they can certainly see its effect on the ocean tides. But did you know that the Moon also causes tides on the land as well? Every time itâs overhead the ground youâre standing on is higher by a few centimetres.
Professor Neil Comins, author of the book What If the Moon Didnât Exist, explains why the tides are the reason the Moon is moving away from Earth â and it has been ever since it was first formed.
And how was it formed anyhow? We turn back time with Prof. Sara Russell from the Natural History Museum in London to discover one of the most dramatic events in the early history of our solar system... when two worlds collided.
And, of course, it helps to know what a dinosaur weighed in the first place. Anand turns to paleontologist Nicolas Campione, whoâs been puzzling over the most accurate way to calculate the bulk of a Brontosaurus.

18 is the age of majority, or maturity, in most countries around the world. Depending where you live, it might be when you can vote, buy alcohol, or get married. But what's so special about 18 that makes it the beginning of adulthood? CrowdScience listener Lynda didn't feel very mature back then. She recalls a difficult decision that made her wonder what science has to say about when weâre truly grown up. How developed are we, physically, mentally and emotionally, by the age of 18? And how much does this differ between people, or from culture to culture? Presenter Caroline Steel digs around for answers with the aid of neuroscientist Sarah-Jayne Blakemore, biological anthropologist Barry Bogin, and cultural anthropologist Bonnie Hewlett. And even some teenagers.

An apex predator is a killer. Usually large and terrifying, they enjoy the privilege of life at the top of a food chain. Nothing will eat them, leaving them free to wreak carnage on more vulnerable creatures.
In biology, itâs a term normally reserved for animals like polar bears, tigers and wolves. But CrowdScience listener Eoin wonders whether thereâs a non-animal candidate for apex predator: the car. After all, worldwide, more than 1.5 million humans die on the roads each year, while pollution from traffic kills millions more. And thatâs just the impact on us. What are cars doing to all the other species on this planet?
Host Anand Jagatia hits the road to investigate. En route, weâll be picking up some scientists to help answer the question. It turns out to be so much more than a question of roadkill: cars, and the infrastructure built to support them, are destroying animals in ways science is only now revealing.
How did the wildlife cross the road? We go verge-side to test four different approaches. And we hear how cars manage to kill, not just on the roadside, but, in the case of some salmon species, from many miles away. Gathering as much evidence as possible, we pass judgement on whether the car truly is an apex predator.

Many of us experience an inner voice: we silently talk to ourselves as we go about our daily lives. CrowdScience listener Fredrick has been wondering about the science behind this interior dialogue. We hear from psychologists researching our inner voice and discover that itâs something that begins in early childhood. Presenter Caroline Steel meets Russell Hurlburt, a pioneering scientist who devised a method of researching this - and volunteers to monitor her own inner speech to figure out whatâs going on in her mind. She discovers that speech is just part of whatâs going on in our heads, much of our inner world in fact doesnât involve language at all but includes images, sensations and feelings. Caroline talks to psychologist Charles Fernyhough, who explains one theory for how we develop an interior dialogue as young children: first speaking out loud to ourselves and then learning to keep that conversation going silently. No one really knows how this evolved, but keeping our thoughts quiet may have been a way of staying safe from predators and enemies. Using MRI scanning, Charles and Russell have peered inside peopleâs brains to understand this interior voice and found something surprising: inner dialogue appears to have more in common with listening than with speaking.
Caroline also has an encounter with a robot that has been programmed to dialogue with itself. Which leads us to some deep questions: is our inner voice part of what makes us human, and if so, what are the consequences of robots developing this ability? Scientist Arianna Pipitone describes it as a step towards artificial consciousness.

It would be quite a superpower to regrow entire body parts. CrowdScience listener Kelly started pondering this after a discussion with her friend on whether human tongues could regrow. Finding out that they couldn't, she asked us to investigate the extent of human regenerative abilities.
Presenter Alex Lathbridge travels to Vienna, a hotbed of research in this area. He meets an animal with much better powers of regeneration than humans - the axolotl. In Elly Tanakaâs lab he finds out how she studies their incredible abilities â and shows off his new axolotl tattoo.
Why can these sweet-looking salamanders regrow entire limbs while we canât even regrow our tongues? Palaeontologist Nadia Fröbisch has looked into the evolutionary origins of regeneration, and it goes a lot further back than you might think.
And in fact, even humans are constantly regenerating, by renewing the building blocks of our bodies: cells. New cells grow and replace old ones all the time â although, in some parts of the body, we do keep hold of the same cells throughout our lives.
However, cell turnover isnât the same as regrowing entire organs or limbs. But can we grow new body parts in the lab instead? We meet Sasha Mendjan, who creates heart organoids using our cellsâ innate ability to self-organise. How far off are we from implanting organs, grown from a patientâs stem cells, back into the human body?

Why do we have two eyes? Two ears? Two arms and two legs? Why is one side of the human body â externally at least â pretty much a mirror image of the other side?
CrowdScience listener Kevin from Trinidad and Tobago is intrigued. He wants to know why human beings â and indeed most animals - have a line of symmetry in their bodies. Yet, beyond their flowers and fruits, plants donât seem to have any obvious symmetry. It seems that they can branch in any direction.
Anand Jagatia sets out to find out why the animal kingdom settled on bilateral symmetry as the ideal body plan. And it takes him into the deep oceans of 570 million years ago. Paleobiologist Dr. Frankie Dunn is his guide to a time when animal life was experimenting with all sorts of different body plans and symmetries.
Frankie shows Anand a fossil of the animals which changed everything. When creatures with bilateral symmetry emerged they began to re-engineer their environment, outcompeting everything else and dooming them to extinction.
Well... nearly everything else. One very successful group of animals which have an utterly different symmetry are the echinoderms. That includes animals with pentaradial - or five-fold - symmetry like starfish and sea urchins. And that body shape poses some intriguing questions... like âwhereâs a starfishâs head?â Dr. Imran Rahman introduces us to the extraordinary, weird world of echinoderms.
To answer the second part of Kevinâs question - why plants donât seem to have symmetry â Anand turns to botanist Prof. Sophie Nadot. She tells him that there is symmetry in plants... you just have to know where to look! Beyond flowers and fruits, thereâs also symmetry in a plants leaves and stem. The overall shape of a plant might start out symmetrical but environmental factors like wind, the direction of the sun and grazing by animals throws it off-kilter.
And, while the human body may be symmetrical on the outside, when you look inside, itâs a very different story. As listener Kevin says, âour internal organs are a bit all over the place!â Prof. Mike Levin studies the mechanisms which control biological asymmetry. He tells Anand why asymmetry is so important... and also why itâs so difficult to achieve consistently.

It's a simple metal box that moves nearly all of our goods around the world. Designed for uniformity and interchangeability, the shipping container has reshaped global trade and our lives in the nearly 70 years since its creation.
But listener Paul wants to know if these heavy steel containers could be made with lighter materials to cut down on the fuel needed to transport them, especially when they're empty. Could we make shipping containers a more efficient process and reduce the shipping industryâs sizable greenhouse gas emissions?
Host Anand Jagatia travels to Europe's largest port in Rotterdam looking for answers. Speaking to environmental scientists and industry insiders along the way, he takes a look at how the humble container might be modified to once again remake global shipping, from materials, to designs, to how itâs shipped. And thinking outside the box, we explore which innovations might benefit the whole system â from machine learning to new, carbon-free energy sources.
For an industry thatâs not always quick to change, we speak with the changemakers trying to disrupt the way 90% of the stuff we buy moves, in hope of a greener future.

When listener Watum heard about the Titan submersible implosion in the news in 2023, a question popped up in his mind: if a machine that we specifically built for this purpose cannot sustain the water pressure of the deep ocean, how do fish survive down there?
In this episode, we travel with marine biologist Alan Jamieson to the second deepest place in our oceans: the Tonga trench. Meanwhile, presenter Caroline Steel speaks to Edie Widder about the creatures that illuminate our oceans, and travels to Copenhagen to take a closer look one of the strangest deep sea creatures and its deep sea adaptations.
But even fish have their limits! Scientist Paul Yancey correctly predicted the deepest point that fish can live, and it all comes down to one particular molecule.
So is there anything living beyond these depths? Well, there is only one way to find outâŠ

CrowdScience listener Azeddine from Algeria has had bad handwriting since he was a child. In fact, it was so untidy that, when he later became a chemistry lecturer, his university students complained that they could not read his lecture notes. That was when he decided he had to do something about it. And it got him wondering⊠why do some of us have very neat handwriting while other peopleâs is almost unreadable? Why do his sisters all write beautifully when his natural style is quite the opposite? Presenter Alex Lathbridge sets out to answer Azeddineâs question. He explores the different factors which determine how well we write. How much of it is inherited? What part does family and education play? And what is actually going on in our brains when we apply pen to paper? Alex talks to anthropologist Monika Saini of the National Institute of Health and Family Welfare, Delhi, who has analysed writing styles within families and in different regions across India. She tells him about the genetic and cultural factors which seem to influence our handwriting. We also hear from neuroscientist Marieke Longcamp of Aix Marseille UniversitĂ©, France, who uses MRI scanning to find out which parts of our brains are involved when we write by hand. She has looked at what is happening in the brains of people who write in more than one script â for example in French and Arabic, like Azeddine. Another neuroscientist, Karin Harman James, from Indiana University, USA ,has been looking at the link between learning something by writing it down compared to typing it on a tablet or laptop. And Alex meets handwriting tutor Cherrell Avery to find out if itâs possible to improve your writing â even as an adult.

In many languages across the world, all nouns are classed as either male or female, or sometimes neuter. The English language, however, only signals gender in its pronouns - he, she, it or they. For inanimate objects, gender just crops up in occasional examples like ships or countries, which, for some reason, are deemed female. This lack of gender in English intrigued CrowdScience listener Stuart, since the other languages he knows all highlight whether something is male or female. Did English ever have gender, and if so, where did it go? Presenter Anand Jagatia dives into some Old English texts to uncover the idiosyncrasies of its masculine and feminine nouns, and learns why these gradually fell out of use. But why do other languages assign gender to nouns â male, female, and sometimes many more categories too? And does this affect the way we think?

Buildings inspire many emotions, like awe, serenity or even dread. CrowdScience listener Siobhan was struck by this as she passed a huge apartment block with tiny windows; it reminded her of a prison. So, she asked us to investigate the feelings that buildings can trigger. Architects have long considered how the effect of buildings on their occupants or passersby: asking whether certain features elicit feelings of wonder or joy... or sadness and fear. And now modern neuroscience has started to interrogate these very questions, too. How much of the way we feel about a building is to do with its intrinsic design, and how much is due to our individual brain chemistry and life experiences? Presenter Caroline Steel talks to designer Thomas Heatherwick about his ideas for improving public spaces; enters a virtual reality simulation in Denmark to learn about the emerging field of âneuroarchitectureâ; and finds out why people just canât agree what makes a âgoodâ or âbadâ building.

How do you think about the internet? What does the word conjure up? Maybe a cloud? Or the flashing router in the corner of your front room? Or this magic power that connects over 5 billion people on all the continents of this planet? We might not think of it at all, beyond whether we can connect our phones to it.
Another chance to hear one of our favourite episodes, inspired by a question from CrowdScience listener Simon: how much does the internet weigh?
First of all, this means deciding what counts as the internet. If it is purely the electrons that form those TikTok videos and cat memes, then you might be surprised to hear that you could easily lift the internet with your little finger. But presenters Caroline Steel and Marnie Chesterton argue that there might be more, which sends them on a journey.
They meet Andrew Blum, the author of the book Tubes â Behind the Scenes at the Internet, about his journey to trace the physical internet. And enlist vital help from cable-loving analyst Lane Burdette at TeleGeography, who maps the internet.
To find those cables under the oceans, they travel to Porthcurno, once an uninhabited valley in rural Cornwall, now home to the Museum of Global Communications thanks to its status as a hub in the modern map of worldwide communications. With the museumâs Susan Heritage-Tilley, they compare original telegraph cables and modern fibre optics.
The team also head to a remote Canadian post office, so correspondent Meral Jamal can intercept folk picking up their satellite internet receivers, and ask to weigh them. A seemingly innocuous question becomes the quest for everything that connects us... and its weight!

Snakes are often seen as slithery, slimy and scary. But these intriguing non-legged creatures have made CrowdScience listener Okello from Uganda wonder how they move â more specifically, he wants to know how they climb trees so easily, and so fast.
Presenter Caroline Steel meets snake expert Mark OâShea to investigate the ingenious methods different snakes use to scale a tree trunk, and gets a demonstration from a very agreeable corn snake at a zoo.
Snake movement isnât just your typical S-shaped slithering: these reptiles move in a remarkably diverse range of ways. Melissa Miller from the University of Florida explains all the range of motion snakes can employ to effectively travel along the ground as well as at height.
Caroline witnesses this in action as we pay a steamy visit to the Everglades National Park in Florida, USA, tracking pythons across the vast swamps there. We find out why understanding these pythonsâ movement is vitally important for conserving the local ecosystem.
