The Mosquito Conundrum
The doctors put mosquitoes on trial, as listener Cathy in the UK asks, ‘What is the point of mosquitoes?’ in response to our show about wasps. Mosquitoes have undeniably played a role in killing millions of people. Malaria is the single biggest cause of death in human history. But Erica McAlister, senior curator of flies and fleas at the UK’s Natural History Museum, reveals that not all mosquitoes are interested in biting us for a blood meal, or are involved in transmitting disease. Only the females of about 10 species are the most problematic for humanity, from around 3600 true species of mosquito. Limited research indicates that many play important roles in ecosystems, for example as pollinators on land and as food sources during their larval stage in aquatic environments. Nonetheless, those roughly 10 species cause devastating disease. Kate Jones’ research at University College London examines the interface of ecology and human health. Malaria and dengue fever alone cause over 300 million infections annually. And there are many more diseases transmitted by mosquitoes: Zika, West Nile fever, Yellow fever, Japanese encephalitis – the list goes on, and with urbanisation and climate change, the picture is constantly changing. So what can be done? Should we try to annihilate the disease-carrying species? Insecticide use has historic and ongoing controversy, as the difficulties of needing to stop deaths in the short term risks longer term environmental damage, with unforeseen and possibly greater consequences for humanity. So Adam turns to new, genetic technology with zoologist Matthew Cobb. Can and should we modify mosquitoes to wipe themselves out, by wrecking local populations with sterile males, or use a technique called a gene drive to perpetuate debilitation through generations? Or could life find a way to evolve past our attempts at control, and cause greater problems? The doctors deliberate and try to decide a verdict on mosquitoes’ fate.

The Scientific Exploration of Astrology
Astrology – could there be something to it? asks Dan from Australia. Rutherford and Fry investigate the science that has investigated astrology. Professor Richard Wiseman, (sceptical of all things paranormal and a Virgo) and Professor in the Public Understanding of Psychology at the University of Hertfordshire, explains the long history of the scientific investigation of astrology. He has also run his own experiments to test whether astrology can help you play the stock market and to investigate if people born in the summer are luckier than those born in the winter – the results may surprise you. Journalist and author, Jo Marchant (Leo and fascinated non-believer) has written all about the history of astrology in her new book – 'The Human Cosmos – A Secret History to the Stars'. In the beginning astrology and astronomy were one and the same. She explains how astrology flourished with the elite and ruling classes of ancient Babylon, Egypt and Greece. Data scientist, Alex Boxer (Taurus and cautious astrology tourist) explains that astrology may have been humanity's first attempt to predict the future with algorithms, something we’re doing more and more of now. In his book, ‘A scheme of heaven, astrology and the birth of science’, he describes how astrological and scientific algorithms are all just big data science looking for patterns. The issue lies in what that data is. Presenters: Hannah Fry (Pisces) & Adam Rutherford (Capricorn) Producer: Fiona Roberts (Libra)

The Noises That Make Us Cringe
Why do some people find noises like a fork scraping a plate so terrible? asks Findlay in Aberdeenshire. Rutherford and Fry endure some horrible noises to find out the answer. Warning - This episode contains some horrible sounds Trevor Cox, Professor of Acoustic Engineering at the University of Salford, has run experiments to find out the worst, most cringe-making sound. He divided horrible sounds into three categories: scraping sounds, like nails down a blackboard; disgusting sounds like a snotty sniffy nose; and sounds that make us cringe because of what we associate them with, like the dentist’s drill. All horrible sounds have some sort of association whether it’s a primal scream or fear of catching a disease, and they’re dealt with in the ancient part of the brain – the amygdala. Professor Tim Griffiths is a Cognitive Neurologist at Newcastle University’s Auditory Cognition Group. He has been studying people with misophonia, a condition where ordinary, everyday sounds, such as someone eating or breathing causes a severe anxiety and anger response. Misophonia may affect around 15% of the population and Tim thinks that different parts of the brain – the insula and the motor cortex - are involved in this fight or flight response to seemingly innocuous sounds. Cat Thomas’s job is to make horrible sounds. She is a foley artist at Boompost. If you watch Call the Midwife or Peaky Blinders, all the incidental sounds are created by Cat and her team. She also created some of the sounds for the horror film Camilla, which involved evisceration and disembowelling with the aid of some squishy oranges and bananas. Adam Rutherford and Hannah Fry try their own horror sounds when they chop off a finger with the aid of some large pasta shells, an orange and a knife.

The Pizza Diet
Can I make a pizza that contains my recommended daily intake of everything? asks listener Paul in Manchester. We investigate whether a pizza can meet our full dietary requirements. The optimum diet for humans has been long contested. From William the Conqueror's alcohol diet to the infamous apple cider vinegar diet, discovering the healthiest nutrition is a centuries-long work in progress. So could The Pizza Diet be the next food fad? We investigate a theory that a basic margherita pizza – with its components of a flour-filled base, along with a cheese topping – should meet our needs for carbohydrate, protein and fat. Adam meets up with body-weight geneticist Giles Yeo from their respective kitchens for a remote cook-off to find out if it's possible to make this mythical one-meal wonder in practice. On closer inspection of the evidence-based government dietary requirements, this task appears somewhat challenging. Dietitian Clare Thornton-Wood analyses the components of a margherita and unsurprisingly finds they do not entirely meet the guidance. She then scrutinises our attempt to retrofit a recipe that might do the job. Giles attempts to put our proposed pizza into practice. He has to ad-lib, as the resultant mountain of eclectic toppings – chickpea and sweetcorn pizza, anyone? – and giant base won’t fit in his oven. Disappointingly for hardcore pizza fans like Paul who may be attempting healthier eating habits in 2021, it seems that this particular approach is not the way forward. Food choice psychologist Suzanna Forwood explains why there is so much more to our dietary decisions than digestive physiology, and offers tips for listeners hoping to make seasonal steps in a healthy direction.

The Good and Bad in Fungi
"Why are some fungi helpful and others harmful?" asks Paul Glaister in Reading. Rutherford and Fry try to outdo each other with fungal top trumps to get to grips with the answer. Decomposition ecologist Lynne Boddy, Professor of Microbial Ecology at Cardiff University, helps Hannah calculate the amount of dead plant material we’d be buried in across the globe, if we didn’t have fungi to recycle it. And she describes her first fungal encounter in her student flat which was riddled with dry rot, and explains how without fungi, we wouldn’t have plants. On Adam’s team is Curator of Mycology, Dr. Bryn Dentiger, at the Natural History Museum of Utah. Bryn tells Adam that he can’t think of a single food that doesn’t have some association with fungus. And the links are mostly positive rather than just mould on the top of your jam or rotten fruit in your fridge. He introduces Adam to the Humungous Fungus – the biggest living organism on Earth - and they get excited at the prospect of 20,000 different fungal sexes. The pros and cons of fungi don’t stop there. Microbiologist Dr. Ada Hagan,in Michigan lists some of the fungal diseases we’re prone to, and the numerous drugs derived from fungi that help treat a whole host of common diseases.

The Martian Mission
What would it take for humans to live permanently on Mars? asks Martin in Weston-super-Mare, UK. The doctors dig into requirements and possibilities of a long-term Martian outpost. We know that many missions to Mars have failed, for a range of reasons – malfunctions, crashes and even a mix-up between imperial and metric units. Getting to Mars – let alone decelerating from 30,000 miles per hour to a safe landing speed in about seven minutes – is not straightforward. Aerospace engineer Anita Sengupta helped land NASA’s Curiosity rover on Mars. She knows first-hand the challenges of putting a robot on the red planet. But getting robots to Mars is an easier proposition than doing the same for humans. Even if we work out how to survive the radiation exposure on the eight-month journey and the pulverising descent, Mars’ surface isn’t easily habitable. Principal investigator for NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) Bruce Jakosky describes the conditions on Mars: Freezing, with an atmosphere containing mostly carbon dioxide and very little water, and subject to annual global dust storms. However, this isn’t deterring space agencies and private companies from researching the challenge. The European Space Agency and Russian Institute for Biomedical Problems focussed on finding out the physiological and psychological tolls by selecting six candidates to spend 520 days in a simulated spacecraft and landing module. Diego Urbina explains the personal challenge of taking part in the Mars500 experiment. Some private company owners have gone even further. As well as making technology based on the current physical conditions, could those constraints themselves be altered? Could Mars be terraformed, or warmed, for easier human survival? Bruce Jakosky shares just what that would take – and compares these requirements with what’s actually available.

The Hamster Power Hypothesis
"How many hamsters on wheels would it take to power London?" asks Judah from Virginia in the USA. Rutherford & Fry return with engineering, ethics and economics to answer this electric query. Smart grid engineer Lynne McDonald helps keep the lights on for 8.3 million homes and businesses across London at UK Power Networks. She explains how the kilowatt hours we see on our electricity bills relate to the thousands of gigawatt hours required when thinking about powering the whole of London. In theory, a hamster in a wheel might be able to produce about half a watt of power – enough to run a small LED light bulb. Whilst the doctors argue the case on the resultant practicalities and ethics of even considering such a scenario – as, for example, the required cubic kilometre stack of hamster habitats would cover Canary Wharf – Royal Veterinary College researcher Zoe Davies points out some biological and anatomical home truths. As an expert in biomechanics currently investigating athletic performance in racehorses, she walks Adam through the impossibilities of using pretty much any animal, bird or insect as a source of power. There may be one exception though: humans. Veteran lecturer of undergraduate chemistry for biologists and cycling enthusiast, Andrea Sella discusses whether human power might realistically work. We consider what this or other more realistic sources of renewable energy could mean for the future of our national grid.

The Zedonk Problem
‘Today I learnt that tigons and ligers are what you get when lions and tigers interbreed?!’ surprised listener Jamz G tells the doctors. ‘What determines whether species can interbreed?’ Geneticist Aoife McLysaght studies molecular evolution. She explains the modern definition of a species, built on ideas from Aristotle, Linnaeus and Darwin: a species is a group of organisms capable of interbreeding to produce fertile offspring. Hybrids – such as ligons and tigers – are usually infertile, because their common ancestors long ago diverged into the lions and tigers we know today. However, this definition isn’t absolute, and there are many ways a new species can be formed. Hybrids also offer rich study subjects for scientists. Mathematical biologist Kit Yates discusses why he’s been reading research papers about hebras and zorses (horse x zebra) as their patterns offer insights into how cells spread and develop into organisms, building on a prediction made by codebreaking mathematician Alan Turing. And it turns out that these hybrids are even more intriguing. As speciation and evolution expert Joana Meier explains, hybrids are not always infertile. Hybridisation can lead to successful new species arising, such as in Lake Victoria’s cichlid fish, who it seems have been having a wild evolutionary party for the last 15,000 years. And the picture gets even murkier when we discover that modern genetics reveals our human ancestors successfully mated with Neanderthals.

The End of Everything
Everyone knows about the Big Bang being the beginning of the universe and time - but when and how is it going to end? ask brothers Raffie and Xe from Rome. For this series, with lockdown learning in mind, Drs Rutherford and Fry are investigating scientific mysteries for students of all ages. The doctors sift science from philosophy to find out. Cosmologist Jo Dunkley studies the origins and evolution of the universe. She explains how astrophysical ideas and techniques have evolved to tell us what we now know about our galaxy and far beyond, from the elegant parallax technique to standard candles. This particular distance measure, which uses stars of a known brightness to work out how far away other objects in the universe are, was discovered by American astronomer Henrietta Swan Leavitt in 1912, who worked at the Harvard University as one of several “computers” – women who processed and calculated data and made significant contributions to astronomy. Curious Cases’ universal guru Andrew Pontzen puts this into context. Because the universe is so enormous, it turns out that these measurements are just the first steps on the cosmic distance ladder – a suite of tools that astrophysicists use to determine distances to celestial objects. Scientists know that objects are moving away from us because the wavelengths of light from them get stretched and appear redder in our telescopes – the so-called red shift effect. But having a handle on the distances to and between those objects allows cosmologists to monitor what’s happening to them over time. And it turns out that not only are they getting further apart, indicating that the universe is expanding, but that this process is accelerating. So what might happen in the end? Expansion and then collapse – a big crunch? Expansion into the void – a big freeze, or a big rip? Or what if there is more than one universe – might a new one bubble up with totally different laws of physics that would cause our own to cease existing? It turns out that when dealing with predictions for something involving infinite space and time, the possibilities are largely limited by human imagination alone. Ideas are where science starts, but experiments are required to build evidence confirming or rejecting them as fact. The doctors discuss how gravitational wave detectors and quantum computers might one day provide this. Presenters: Hannah Fry & Adam Rutherford Producer: Jen Whyntie

The Sting in the Tail
"What’s the point of wasps?" asks listener Andrew, who is fed up with being pestered. For this series, with lockdown learning in mind, Drs Rutherford and Fry are investigating scientific mysteries for students of all ages. Do wasps do anything to justify their presence as a picnic menace? Ecologist Seirian Sumner researches social wasp behaviour and champions their existence. Not only do yellow jacket wasps perform important ecological services as generalist pest controllers of aphids, caterpillars and flies in the UK, they have complex societies and may even perform pollination services, making them more like their better-loved bee cousins than many might think. However, much remains unknown about wasps’ contribution to our ecosystem. Seirian works with entomologist Adam Hart, and together they run The Big Wasp Survey each summer, a citizen science project dedicated to finding out more about UK wasp species and their populations. Prof Hart sets up an experimental picnic with Dr Rutherford to try and attract some native wasps and discusses why they are so maligned. But in some parts of the world UK wasp species have become a major problem. Just after World War II, having unwittingly chosen some aircraft parts destined for New Zealand as their overwintering home, some wasp queens woke up in the city of Hamilton. With no natural predators or competitors, they quickly established a growing population. Fast forward to today, and by late summer the biomass of wasps becomes greater than all the birds, rodents and stoats in the southern island’s honeydew beech forests. Multiyear nests have been discovered that are over three metres tall and contain millions of wasps. Researcher Bob Brown is digging into wasp nests back in the UK to discover which species keep wasps in check here, and whether they might work as biological control. This causes the doctors to ponder the problems of humans moving species around the planet. Accidental or even well-meaning introductions all too often become invasive. As climate change and urbanisation accelerate, wasps may become more helpful in some ways and more harmful in others. Presenters: Hannah Fry, Adam Rutherford Producer: Jen Whyntie

The Seeded Cloud
"Could you make a machine to make it rain in minutes?" asks listener Alexander from Hampshire, aged 12. For this series, with lockdown learning in mind, Drs Rutherford and Fry are investigating scientific mysteries for students of all ages. Rutherford and Fry dive into the clouded story of weather modification. First, we need to decide where and when we might deploy any rain machine. Liz Bentley, Chief Executive of the Royal Meteorological society, takes us through the science, maths and art of predicting the weather. Hannah heads down to the BBC Weather Centre to meet meteorologist Helen Willetts, who takes us through the highs and lows of forecasting. And then for the technology itself. Mark Miodownik, scientist and author of Liquid: The Delightful and Dangerous Substances The Flow Through Our Lives, reveals that a technique called cloud seeding has almost certainly been tried in different places around the world for decades. But, whilst it’s supposed to induce showers and even clear the way for sunny spells, the results aren’t always reliable. And even if we can make it rain, Liz explains why messing with the weather may be at our peril. Presenters: Hannah Fry, Adam Rutherford Producer: Jen Whyntie

The Growling Stomach
"Why do our tummies rumble - and when they do, does it always mean we are hungry?" asks listener James, aged 12. For this series, with lockdown learning in mind, Drs Rutherford and Fry are investigating scientific mysteries for students of all ages. To get to the bottom of this noisy problem, the doctors tune in to our guts. Geneticist Giles Yeo studies food intake and obesity. He explains the wavy workings of our digestive system, and how those audible rumbles are a sign that digestion is taking place – a phenomenon thought to be onomatopoeically named 'borborygmi' by the ancient Greeks, and explored further in the gruesome 19th century experiments of surgeon William Beaumont. However, tuning in to the gut’s sounds can tell us more than whether we need a snack. Family doctor Margaret McCartney takes us through the process of how and why she and her medical colleagues may use a stethoscope to listen to your abdomen for both particular noises and silence. Microbiologist Barry Marshall has taken medical listening one step further in his Noisy Guts Project. Inspired by microphones used to listen for termites hiding in walls, the Nobel Prize-winning scientist is trialling an acoustic belt, which could be worn to help diagnose and treat Irritable Bowel Syndrome.

The Exotic Wormhole
"What are wormholes and do they really exist?" asks Manlee-Fidel Spence, aged 12. In this exotic episode, the doctors investigate how wormholes would work. Cosmologist Andrew Pontzen explains why wormholes could allow you to travel through time as well as space. And physicist Jim AlKhalili outlines the infinite problems this could generate. When it comes to wormholes and time travel, many science fiction stories have married solid science and successful storytelling, as Jennifer Oullette describes, but others really have defied the laws of physics. Jim also reveals why some quantum physicists now think that wormholes could be everywhere. But don't expect to jump back to 1955 any time soon.

A Cold Case Part 2
Two cold callers feature in this episode. Jennifer Langston from Ontario in Canada sent this message to "My husband has just taken up cold water swimming and he'll swim in temperatures as low as 6 degrees Celsius. I worry that it's too cold for him, but he claims that 'swimming in cold water is good for you', which drives me bonkers. Can you tell us if there is any scientific proof behind this?” Adam takes a trip to his local lido and asks the locals why they get a kick out of a chilly winter dip. Meanwhile, Hannah calls the Antarctic to talk to meteorologist Richard Warren about the perils of a frozen beard. Our second cold caller, Sarah Dudley, asks why women get cold feet in bed. Thermal physiologist Heather Massey is on hand with the answer. But when it comes to the natural world, other animals are masters of sub-zero living. Frozen Planet producer Kathryn Jeffs, from the BBC's Natural History Unit, explains why polar bears are perfectly designed for the Arctic. And we discover why Paddington Bear is better suited to Peru. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

A Cold Case Part 1
“I suppose a cold is called a cold because we catch it in the winter," writes Alison Evans from St Albans. "But why is it that we get more colds in winter than in the summer?” This week's Cold Case is all about the common cold, a set of symptoms caused by hundreds of different strains of cold and flu viruses. Adam uncovers the stinky history of infectious disease with medical historian Claire Jones. Virologists Jonathan Ball and Wendy Barclay describe how spiky viruses lock on to our cells, but why many of the symptoms of a common cold are due to our own body's overreaction. Plus, we delve into the science of sneezing with nose doctor Carl Philpott. Presenters: Adam Rutherford, Hannah Fry Producer: Michelle Martin

The ASMRnswer
"My question is about something I became aware of at a young age," explains Samantha Richter from Cambridgeshire. "I was sitting on the carpet at school, being read a story by the teacher. My hair felt as though it was standing on end as waves of a tingly sensation washed over my head. I subsequently found certain scenes in films had this effect, when actors were talking softly, or someone was having their hair brushed." "Then, a few years ago, I discovered that there is a name for the tingles, it's called ASMR. My question is, what is ASMR, and why do we experience it?" In this episode, we explore the world of Autonomous Sensory Meridian Response. It's a trend which has risen quickly on YouTube, with devoted subscribers following their favourite 'ASMRtists' whose videos receive millions of plays. Hannah speaks to Dr Nick Davis, who published the very first research paper on the phenomenon in 2015. And Adam is put to the test by Dr Giulia Poerio, to see if he is susceptible to the sensation of ASMR. Are there any proven benefits for devoted fans, or is it just a YouTube fad? We've concocted our very own Curious recordings so you can find out if your brain begins to tingle, You'll find them in our normal podstream, where you can enjoy Adam and Hannah crafting a very ASMRy cocktail for your listening pleasure.

The Power of Love
Two questions about love and heartbreak in this episode for our Valentine's special edition. Jessica Glasco, aged 29, wrote in to ask about the power of love and how it affects our brain. Hannah tracks down Dr Helen Fisher, who conducted some of the first MRI studies on love by putting besotted couples into the brain scanner. Adam talks to broadcaster Claudia Hammond, author of Emotional Rollercoaster, to find out how psychologists have grappled with the messy business of love. And we hear why a small furry vole was thought to hold the answer to the mystery of monogamy. Our second question concerns the pain of heartbreak - why does our heart ache? Can emotional hurt cause physical pain? On call is our very own agony aunt, Irene Tracey, Prof of Pain Research. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

The Golden Secret
"How do you make gold?" asks curious listener, Paul Ruddick. Inspired by the promise of riches, Hannah and Adam embark on a mission to discover the origin of gold. It's a tale that takes them from the clandestine codes of Aristotle to the alchemy of Isaac Newton, alongside materials scientist Mark Miodownik. They boldly go into the cosmos with astronomers Lucie Green and Andrew Pontzen, to learn what happens in the most exotic areas of space. By the end one thing is for sure - you'll never look at your gold jewellery in quite the same way again. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

The End of the World
"What would become the dominant species if, or when, humans go extinct?" This cheery question leads Drs Rutherford and Fry to embark on an evolutionary thought experiment. Zoologist Matthew Cobb questions whether humans really are the dominant species. Ecologist Kate Jones explains why some species are more extinction-prone than others. Plus Phil Plait, AKA The Bad Astronomer, busts some myths about why the dinosaurs went extinct.

The Trouble Sum Weather
"Why is it so difficult to predict the weather?" asks Isabella Webber, aged 21 from Vienna. "I am sure there are many intelligent meteorologists and it seems rather straight forward to calculate wind speed, look at the clouds, and data from the past to make accurate predictions, but yet it’s not possible." Adam delves into the history of forecasting with author Andrew Blum, beginning with the mystery of a lost hot air balloon full of Arctic explorers. Hannah visits the BBC Weather Centre to talk to meteorologist and presenter Helen Willetts about how forecasting has changed, and whether people get annoyed at her if she gets the forecast wrong. Plus mathematician Steven Strogatz suggests a chaotic explanation as to why we can't produce the perfect forecast. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

The Heart of the Antimatter
"How do you make antimatter?' asks Scott Matheson, aged 21 from Utah. The team takes charge of this question with a spin through the history of antimatter. Adam talks to physicist Frank Close, author of 'Antimatter', about its origins in the equations of Dirac to its manufacture in the first particle accelerator, the Bevatron. Cosmologist Andrew Pontzen tells Hannah why physicists today are busy pondering the mystery of the missing antimatter. Anyone who discovers why the Universe is made of matter, rather than antimatter, is in line for the Nobel Prize. Plus, neuroscientist Sophie Scott describes how antimatter has been put to good use down here on Earth to peer into people's brains. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

Stephen Fry's Identity Crisis
Stephen Fry (no relation) asks Adam and Hannah to investigate the following question: "All my life I have been mildly plagued by the fact that I have a quite appalling ability to remember faces. I cut people I should know well dead in the street, or at least fail to recognise them in a way which must often be hurtful. At a party I can talk to someone for ten minutes and then see them again twenty later and have no idea who they are unless I’ve made an effort to fix some accessory or item of their dress in my mind. If I see them the next day in another context I’ll have no idea who they are. It’s distressing for me inasmuch as I hate the idea that people might think I am blanking them, or think little of them, don’t consider them significant and so forth. I’d be very grateful if my sister-in-surname and her eximious partner Adam could investigate prosopagnosia for me and offer any hint add to as to its cause or even possible – I won’t say “cure” as I am sure it’s chronic and untreatable – but at least any interesting ways of relieving it." Hannah and Adam call in the experts, neuroscientists Sophie Scott and Brad Duchaine. Why is it that some people struggle with prosopagnosia, whilst others never forget a face?

A Frytful Scare Part 2
Rutherford and Fry delve into the history of roller coasters in the second instalment of their investigation into why we enjoy being scared. Amelie Xenakis asks: "Why do people enjoy roller coasters? I am a thrill-seeker and I am always terrified before riding a roller coaster but I enjoy the ride itself. (I would like BOTH of you to ride a roller coaster if possible)." Never ones to shy away from a challenge, the pair attempt to channel their inner adrenaline junkies with a trip on one the UK's scariest roller coasters at Thorpe Park. They discover the birth of the roller coaster in the 18th century, when Catherine the Great enjoyed careering down Russian Ice Mountains covered in snow. Adam talks to scary sociologist Margee Kerr, author of 'Scream! The Science of Fear', about how the modern roller coaster evolved. David Poeppel from New York University studies the science of screaming, and we discover what makes screams uniquely terrifying. Plus, psychologist and broadcaster Claudia Hammond describes some early experiments which tested how fear affects our body. Presenters: Adam Rutherford, Hannah Fry Producer: Michelle Martin

A Frytful Scare Part 1
It was a dark and stormy night around the time of Halloween. A secret message arrived addressed to Rutherford & Fry from a mysterious woman called Heidi Daugh, who demanded to know: "Why do people like to be scared? For example, going on scary amusement park rides and watching horror movies that make you jump.” What followed was an investigation over two chapters, which would test our intrepid duo to their very limits. In this first instalment, they explore the history of horror, starting with its literary origins in the Gothic fiction classic 'The Castle of Otranto'. Adam challenges Hannah to watch a horror film without hiding behind a cushion. She quizzes horror scholar Mathias Clasen to find out why some people love the feeling of terror, whilst it leaves other cold. Sociologist Margee Kerr and psychologist Claudia Hammond are also on hand to explore why scary movies are so powerful and popular. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

Jurassic Squawk
"Is there is any way of knowing what noises, if any, dinosaurs would have made?" asks Freddie Quinn, aged 8 from Cambridge in New Zealand. From Jurassic Park to Walking with Dinosaurs, the roars of gigantic dinosaurs like T.Rex are designed to evoke fear and terror. But did dinosaurs actually roar? And how do paleontologists investigate what noises these extinct animals may have produced? Hannah and Adam talk to dinosaur experts Steve Brusatte and Julia Clarke to find out.

The Lunar Land Pt2
In the second installment of our double episode on the Moon we ask what life would be like if we had more than one Moon. From the tides to the seasons, the Moon shapes our world in ways that often go unnoticed. And, as we'll find out, it played a vital role in the creation of life itself. This week we celebrate the many ways the Moon and the Earth are linked. If one Moon is so great, why not have two? We discover why multiple moons could spell disaster for our planet, from giant volcanoes to cataclysmic collisions. Featuring astronomer Brendan Owens from the Royal Observatory Greenwich and physicist Neil Comins, author of 'What if the Earth had two Moons?'. Presenters: Adam Rutherford, Hannah Fry Producer: Michelle Martin

The Horrible Hangover
"My name is Ava and I've never had a hangover," writes Ava Karuso. "I'm a 25 year-old Australian and I enjoy going out for drinks. However, the next day when everyone else sleeps in and licks their wounds, I get up early and get right back to my normal routine.” Drs Rutherford and Fry investigate the ancient origins of alcohol, from Sumerians drinking beer through straws, to Aristotle's teachings ‘On Intoxication’. But what can modern science tell us about how alcohol affects our brains? What causes the morning-after hangover and do some drinks make you feel worse than others? Are there any hangover cures that have been scientifically validated? Featuring health psychologist and hangover researcher Sally Adams, chemist Andrea Sella and science writer Adam Rogers, author of 'Proof: The Science of Booze'.

Two Infinities and Beyond Part 2
This is the second part of our eternal quest to investigate infinity, inspired by this question from father and son duo Sorley and Tom Watson from Edinburgh: “Is anything in the Universe truly infinite, or is infinity something that only exists in mathematics?” Hannah and Adam try and find something that is truly infinite, from the infinitely small particles that live in the subatomic world to the infinitely dense heart of a black hole. But how about the Universe itself? We find out how physicists go about measuring the shape of the Universe, with the help of an orange and a game of Asteroids. Plus, we consider the possibility that the Universe might be finite and have an edge. If so, what's on the other side? Theoretical physicist Sean Carroll from Caltech and cosmologist Andrew Pontzen from University College London help us navigate our biggest question yet. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin

The Déjà Vu
"Do we know what causes déjà vu?" asks Floyd Kitchen from Queenstown in New Zealand. Drs Rutherford and Fry investigate this familiar feeling by speaking to world-leading reseacher Chris Moulin from the University of Grenoble in France and memory expert Catherine Loveday from Westminster University. Plus, they find out why early investigations classed déjà vu as a type of paranormal phenomenon. For most of us, it's a fleetingly strange experience, but for some people it can become a serious problem. Lisa from Hulme in Manchester started experiencing déjà vu when she was 22 with episodes that could last all day. The origin of her déjà vu has been the key to helping psychologists investigate its cause. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Human Instrument
"What happens to the human voice as we age? If I hear a voice on the radio, I can guess roughly how old they are. But singer's voices seem to stay relatively unchanged as they age. Why is this?" All these questions were sent to by Jonathan Crain from Long Island in New York. The Doctors discover how the human voice is produced and listen to how our voice sounds when it emerges from our vocal cords. Acoustic engineer Trevor Cox, author of 'Now You're Talking', explains why German and French babies have a different accent. And neuroscientist Sophie Scott describes what happens when boys' voices break, and why a similar thing can happen to women during the menopause. Finally, our voices often change dramatically in later life, as demonstrated by impressionist Duncan Wisbey from Radio 4's Dead Ringers. Expect cameos from David Attenborough, Dumbledore and Paul McCartney. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Fifth Dimension
"What is the fifth dimension?" asks Lena Komaier-Peeters from East Sussex. Proving the existence of extra dimensions, beyond our 3D universe, is one of the most exciting and controversial areas in modern physics. Hannah and Adam head to CERN, the scientific cathedral for quantum weirdness, to try and find them. Theoretical physicist Rakhi Mahbubani explains why we think that dimensions beyond our own might exist. Adam meets Sam Harper, who has spent 14 years hunting for an elusive particle called the 'graviton', which could provide a portal to these extra dimensions. But if they exist, where have these extra dimensions been hiding? Sean Carroll from Caltech explains various ideas that have been dreamt up by physicists, from minuscule hidden planes to gigantic parallel worlds. Producer: Michelle Martin Presenters: Hannah Fry, Adam Rutherford.

The Cosmic Egg
"How do we measure the age of the Universe?" asks Simon Whitehead. A hundred years ago this wouldn't even have been considered a valid question, because we didn't think the Universe had a beginning at all. Even Einstein thought that space was eternal and unchanging. This is the tale of how we discovered that the Universe had a beginning, and why calculating its age has been one of the greatest challenges in modern astronomy. We also uncover the mysterious dark energy that pervades the cosmos and discover why it's been putting a scientific spanner in the works. Helping to unravel today's question are physicists Andrew Pontzen, Jo Dunkley and Jim Al-Khalili. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Atomic Blade
"What makes things sharp? Why are thinner knives sharper? What happens on the molecular level when you cut something?" All these questions came from Joshua Schwartz in New York City. The ability to create sharp tools allowed us to fashion clothing, make shelters and hunt for food, all essential for the development of human civilisation, according to materials scientist Mark Miodownik. We hear from IBM scientist Chris Lutz, who has used one of the sharpest blades in the world to slice up individual atoms. Plus palaeoarchaeologist Becky Wragg Sykes reveals the sharpest natural object in the world, a volcanic glass used by the Aztecs called obsidian. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Tiniest Dinosaur
"What is the tiniest dinosaur?" asks younger listener Ellie Cook, aged 11. Today's hunt takes us from the discovery of dinosaurs right up to the present day, which is being hailed as a 'golden age' for palaeontology. One new species of dinosaur is currently being unearthed on average every single week. But what's the smallest dino? And what can size reveal about the life of extinct animals? Hannah goes underground at the Natural History Museum to look through their vaults in search of the tiniest dinosaur with palaeontologist Susie Maidment. Meanwhile Adam chats to dinosaur expert Steve Brusatte from Edinburgh University about why size really does matter, especially when it comes to fossils. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Enigma of Sex, Part 2
The second instalment in our double bill on the science of sex, answering this question from Robert Turner, a Curio from Leeds: "Why do we only have two sexes?" Drs Rutherford and Fry look for anomalies in the animal kingdom that go beyond the traditional mechanics of human reproduction. Biologist and author Carin Bondar describes some of the wild and somewhat disturbing ways other animals like to do it. Take the hermaphrodite sea slug who races to stab its penis into its partner's brain during sex, or the female redback spider who loves to indulge in a spot of post-coital cannibalism. But the greatest number of different sexes is found in the world of fungi. Some species can have hundreds of distinct mating types. Fungal ecologist Lynne Boddy explains how mushrooms have sex and why on earth they need so many polygamous partners. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Enigma of Sex, Part 1
"Why do we only have two sexes and are there any anomalies in the animal kingdom?" asks Robert Turner from Leeds. From reptilian virgin births to hermaphrodite sea slugs, over the next two episodes Drs Rutherford and Fry examine the weird ways other creatures reproduce. In this first instalment, they tackle what's been called 'the hardest problem in evolutionary biology' - why does sex exist? Why aren't we all one single sex that clone ourselves to produce offspring? It makes perfect evolutionary sense - you could pass on all of your genes and don't need to bother finding a partner. Hannah visits London Zoo to meet a fierce komodo dragon named Ganas, the result of a virgin birth. And Adam meets some tiny bdelloid rotifers, microscopic worm-like females who have survived for 50 million years by cloning themselves.

Goldfinger's Moon Laser
"The other day I was watching the James Bond film Goldfinger. He boasts a laser powerful enough to project a spot on the Moon. Is this possible? If so, just how powerful would such a laser need to be?" This curious question was sent to by Eddie Griffith from Hinckley in Leicestershire. Adam visits one of the most powerful lasers in the world, the Gemini Super Intense Laser at the aptly named Rutherford Appleton Laboratory in Didcot, Oxfordshire. Plasma physicist Ceri Brenner gives him a quick zap, whilst explaining what would happen if they attempted to shoot their quadrillion watt laser at the Moon. Hannah talks to Tom Murphy from the University of California San Diego, who fires lasers at the Moon for a living. However, unlike Goldfinger, he's not using his Moon Laser for crime, he's using it for science. Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin.

The Dreadful Vegetable
"Why don't children like vegetables?" asks Penny Young from Croydon, and every parent ever. This week Rutherford and Fry dig into the science of taste and discover that there may be more to this question than meets the eye. Children and adults have a different taste experience when they eat the same foods. When you're young, foods can taste saltier and more bitter. What's more, as Jackie Blisset, Professor of Childhood Eating Behaviour explains, there are even evolutionary reasons why toddlers avoid vegetables. For most children it's a phase, but a minority of adults are also labelled as fussy eaters. According to food psychologist Linda Bartoshuk, they are probably what's known as 'supertasters'. Supertasters live in a neon taste world where vegetables are more bitter, and chillies are unbearably hot. Adam sets out on a quest to find potential supertasters in the Radio 4 offices. First stop, the Today programme where Nick Robinson and Sarah Montague become his experimental guinea pigs, with surprising results.

The Cat Who Came Back
"How on earth do cats find their way back to their previous home when they move house?" asks Vicky Cole from Nairobi in Kenya. Our enduring love for our feline friends began when Egyptian pharaohs began to welcome domesticated moggies into their homes. Pictured reclining in baskets at the feet of royalty, pet cats soon became fashionable throughout society in Egypt. Today they are the most popular pet in the world, and home is definitely where their hearts lie. "Whereas dogs are bonded to people, cats are bonded to place," explains zoologist Dr John Bradshaw. "It's very typical for them to try and find their way back to their old house when you move." But how do they do it? And if their navigational skills are so good, why do they get lost?

The Astronomical Balloon
"How far up can a helium balloon go? Could it go out to space?" asks Juliet Gok, aged 9. This calls for some fieldwork! Adam travels to the Meteorology Department at the University of Reading where Dr Keri Nicholl helps him launch a party balloon and track its ascent. But this experiment doesn't quite go to plan. Meanwhile, Hannah consults Public Astronomer Dr Marek Kukula, from the Royal Observatory Greenwich, to discover where space begins. And she decides to take matters into her own hands, with the help of a helium canister and some trusty equations, to help answer Juliet's question.

The Broken Stool
"Science tells us that our body houses microbial organisms. Then how much our weight is really our weight? If I am overweight, is it because of my own body cells or excess microflora?" asks Ajay Mathur from Mumbai in India. Adam bravely sends off a sample to the 'Map My Gut' project at St Thomas' Hospital to have his microbes mapped. Prof Tim Spector reveals the shocking results - a diet of fried breakfasts and fizzy drinks has left his guts in disarray. But help is at hand to makeover his bacterial lodgers. Science writer Ed Yong, author of 'I Contain Multitudes', reveals how much our microbes weigh. We're just beginning to discover the vast array of vital functions they perform, from controlling our weight, immune system and perhaps even influencing our mood and behaviour.

The Lost Producer
Why do some people have a terrible sense of direction? The team receive a mysterious message from an anonymous listener who constantly gets lost. Can they help her find the answer? This listener may, or may not, be the team's producer, Michelle. She would like to state that it's not her fault that she has been dealt a bad genetic hand which has led to faulty place cells developing in her brain. And head direction cells that appear to be pointing the wrong way. More understanding should surely be afforded to those who are navigationally challenged. Hugo Spiers from University College London, has devised a free game called 'Sea Hero Quest' which anyone can use to test their navigational skills. Plus Catherine Loveday from the University of Westminster suggests strategies to help those who tend to get lost.

The Hunt for Nothing, Part 2
In the last episode the team started investigating the following inquiry, sent in to 'Is there any such thing as nothing?' They discovered why quantum fluctuations and the Higgs field mean that nothing is impossible. But how about in mathematics? The story of zero is fraught with inspiration, competition and controversy. Banned in Florence and hated by the Church, zero had a rocky road to acceptance after its genesis in India. Hannah talks to author Alex Bellos and hears about his journey to India to see the birth of zero, featuring archive from 'Nirvana by Numbers' on BBC Radio 4. Plus, Adam is sent on a mission to understand calculus and enlists the help of Jeff Heys from Montana State University.

The Hunt for Nothing, Part 1
"Is there any such thing as nothing?" This question from Bill Keck sparked so much head scratching that we have devoted two episodes to this curious quandary. In the first programme, the team considers the philosophy and physics of nothing. As Prof Frank Close, author of "Nothing: A Very Short Introduction" explains, nothing has intrigued great thinkers for thousands of years, from the Ancient Greeks to today's particle physicists. Otto Von Geuricke, the Mayor of Magdeburg in Germany, invented the artificial vacuum pump in the 17th century and presented spectacular displays to demonstrate the awesome power of nothing. Cosmologist Andrew Pontzen helps Hannah search for nothing in the depths of space and inside the atom. However, as they find out, recent discoveries in physics involving quantum fluctuations and the Higgs field have proved that nothing is impossible.

The Melodic Mystery
'Why is my mother tone deaf?' asks listener Simon, 'and can I do anything to ensure my son can at least carry a tune?' Hannah Fry has a singing lesson with teacher Michael Bonshor to see if he can improve her vocal tone, although things don't quite go to plan.* We meet Martin who dislikes music intensely because he has the clinical form of tone deafness, known as amusia. Just as people with dyslexia see words differently to other people, if you have amusia you don't hear melodies in the same way. Adam talks to music psychologist Dr Vicky Williamson from Sheffield University who studies Martin, and others like him, to try and discover why their brains operate differently.

The Strongest Substance
"What is the strongest substance in the universe? Some people say it is spiderweb, because it is stronger than steel. Is it iron? Is it flint? Is it diamond because diamond can be only be cut by diamond?" asks Françoise Michel. Adam and Hannah put a variety of materials, from biscuits to spider web, under the hammer to test their strength. In their quest to find the strongest substance they quiz materials scientist Mark Miodownik, engineer Danielle George and spidergoat creator, Dr Randy Lewis from Utah. Features archive from 'Horizon: Playing God', first broadcast in January 2012.

The Space Pirate
Listener Paul Don asks: "I'm wondering what's the feasibility of terraforming another planet i.e. Mars and if it's possible to do the same thing with something like the moon? Or, why isn't there already a moon-base? Surely that's easier." Adam & Hannah consider moving to another planet, and discover what challenges they would need to overcome to live in space. They consult engineer Prof Danielle George from the University of Manchester and Dr Louisa Preston, UK Space Agency Aurora Research Fellow in Astrobiology. Adam also hears about attempts to recreate a Martian base on a volcano in Hawaii. He calls HI-SEAS crew member Tristan Bassingthwaighte, who has just emerged from a year of isolation.

The Sinister Hand Part 2
In the previous episode the team started investigating the following enquiry, sent in to "What determines left or right handedness and why are us lefties in the minority?" They considered cockatoos, chimpanzees and Hannah's dog, Molly, to discover that humans are unique, with just one in ten of us being left-handed. Today, they look inside the left-handed brain. Some researchers point to a link between left-handedness and impairments like autism or dyslexia. Others claim that lefties are more creative and artistic. So what's the truth? The team consults Professors Sophie Scott, Chris McManus and Dorothy Bishop to find out. Presenter: Adam Rutherford & Hannah Fry Producer: Michelle Martin.

The Sinister Hand Part 1
Neal Shepperson asks, "What determines left or right handedness and why are us lefties in the minority?" When we started investigating this question it became clear that there were just too many scientific mysteries to squeeze into one episode. So there are two whole episodes devoted to this very Curious Case. One in ten people are left-handed, but where does this ratio come from and when did it appear in our evolutionary past? Hannah talks to primatologist Prof Linda Marchant from Miami University about Neanderthal teeth and termite fishing. Adam consults handedness expert Prof Chris McManus from University College London. He's been trying to track down the genes responsible for whether we're right or left handed.

The Tea Leaf Mystery
Today the team examine the chemistry of tea, in answer to the following question sent in by Fred Rickaby from North Carolina: "When we are preparing a cup of tea and the cup contains nothing but hot, brewed tea we need to add milk and sugar. My wife always adds the sugar first, stirs the cup to make sure it is dissolved and then add the milk. So, is that an optimum strategy for adding milk and sugar to a cup of tea?” Adam consults Prof Andrea Sella from University College London about the perfect formula for a cup of tea. Inside his tea factory in Kent, Master Blender Alex Probyn teaches Hannah an unusual method for tasting tea. Most importantly, the duo discovers whether you should add milk first or last. But can tea professionals really tell the difference? If you have any questions for Drs Rutherford & Fry to investigate send them to Presenters: Hannah Fry, Adam Rutherford Producer: Michelle Martin
