Wild Inside: The Aphid

Wild Inside: The Aphid

2024-04-1527:51

The tiny sap-sucking aphid, at just a few millimetres long, is the scourge of many gardeners and crop-growers worldwide, spreading astonishingly rapidly and inflicting huge damage as it seeks to outwit many host plants’ natural defences. With insights and guidance from aphid expert George Seddon-Roberts at the John Innes Centre, Norwich, some delicate dissecting tools, and a state of the art microscope, Professor Ben Garrod and Dr Jess French delve inside this herbivorous insect to unravel the anatomy and physiology that’s secured its extraordinary reproductive success, whilst offering new clues as to how we could curtail its damaging impact in the future.Co-Presenters: Ben Garrod and Jess French Executive Producer: Adrian Washbourne Producer: Ella Hubber Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth
Ominously called the lamb vulture, there are many myths and misconceptions surrounding the bearded vulture. Flying the mountainous ranges across central Asia and eastern Africa, with a wingspan of almost three meters, the bearded vulture is am impressive Old World vulture. Prof Ben Garrod and Dr Jess French are looking past the beautifully coloured plumage, and delving deep inside to learn what this bird of prey really eats and what keeps its great wings aloft.
Wild Inside returns for a new series to take a look at some of our planet’s most exceptional and unusual creatures from an entirely new perspective: the inside. Whilst we can learn a lot from observing the outside, the secrets to the success of any animal – whether they swim, fly, or hop – lies in their complex internal anatomy. How do these wild animals survive and thrive in harsh and changing environments? To truly understand we need to delve inside.Professor Ben Garrod, evolutionary biologist from the University of East Anglia, and expert veterinary surgeon Dr Jess French, open up and investigate what makes each of these animals unique, in terms of their extraordinary anatomy, behaviour and their evolutionary history. Along the way, they reveal some unique adaptations which give each species a leg (or claw) up in surviving in the big, wild world.The series begins with an icon of the outback – known best for its hopping, boxing, and cosy pouch – the red kangaroo. Despite the immense heat and lack of water, these marsupials dominate Australia, with their evolutionary history driving them to success. From the powerful legs which allow them to hop up to 40km an hour, to an unexpected reproductive system that keeps their populations plentiful, Ben, Jess and marsupial expert Dr Jack Ashby reveal a mammalian anatomy which holds many surprises.

Hannah Fry explores two tales of data and discovery.A young researcher gains access to a secretive data set and discovers a system causing harm to the very people it is supposed to help. One day a student makes a discovery which, if true, could shake the intellectual foundations of a global movement, and undermine politicians around the world.Producer: Lauren Armstrong Carter
Millions of women around the world experience the menopause each year; it’s an important milestone, which marks the end of their reproductive years.But every individual's experience of it is personal and unique. In some cultures, there's a stigma about this life stage – it's viewed with trepidation and as something to be dreaded. In other cultures, it's considered to be a fresh start - a time of greater freedom when women no longer have to worry about their menstrual cycles.In this edition, recorded at Northern Ireland Science Festival in Belfast, Claudia Hammond and her expert panel take a global look at the science of the menopause and debunk some myths along the way.As Claudia and her guests navigate their way through the menopause maze, they look at the most recent academic research in this area. They also discuss the physical and psychological symptoms, the lifestyle changes women can make and the different treatments available, including Hormone Replacement Therapy.Claudia also speaks to the American biological anthropologist who has dedicated an impressive 35 years of her life to studying the average age of the menopause in different countries - and finds out how hot flushes vary in different cultures. She also speaks to a doctor who is working hard to make women’s health less of a taboo subject in the community where she works. And she hears from a Professor of Reproductive Science who is setting up the UK's first menopause school.Producer: Sarah Parfitt Co-ordinator: Siobhan Maguire Editor: Holly Squire Sound engineers: Andrew Saunderson and Bill Maul Mix engineer: Bob NettlesImage used with permission of the Northern Ireland Science Festival
Hannah Fry explores two more tales of data and discovery.Gossip and rumour are plaguing a tile manufacturing company. The chatter is pulling morale to new lows, and amid it all, a question hangs in the air: who is spreading it? Can the science of networks find out? And, what is the secret to ageing well? One man believes he may have found the beginnings of an answer, and it is hiding in a convent.Produced by: Ilan Goodman and Lauren Armstrong Carter
Hannah Fry explores two tales of data and discovery.Do orangutans - or humans - experience a midlife crisis? Hidden deep in the data, two economists have found a surprising pattern: happiness is U shaped. And, John Carter has a terrible choice to make. One path offers glory, the other to death. His decision hinges on one graph, but can it help him take the right road?Produced by: Ilan Goodman and Lauren Armstrong Carter
Hannah Fry explores two tales of data and discovery.Two couples are brought together by a tragedy and a tatty piece of paper, which reveals a serial murderer hiding in plain sight. And, across the world in Singapore, a metro system is misbehaving wildly. The rail engineers and company officials are flummoxed. Can data save the day? Produced by: Ilan Goodman and Lauren Armstrong Carter
Hannah Fry explores two tales of data and discovery.In a few specific years across the 20th Century, the proportion of boys born, mysteriously spiked. We follow one researcher’s obsessive quest to find out why. And next, a tale of science and skulduggery. Michael Mann was a respected climate scientist, unknown outside of a small academic circle, until he produced a graph that shocked the world and changed his life forever. Producer: Ilan Goodman
Humans have a long-held fascination with the idea of Artificial Intelligence (AI) as a dystopian threat - from Mary Shelley's Frankenstein, through to the Terminator movies. But somehow, we still often think of this technology as 'futuristic', whereas in fact, it's already woven into the fabric of our daily lives, from facial recognition software to translator apps. And if we get too caught up in the entertaining sci-fi narrative around AI and the potential threat from machines, there is a more pressing danger that we overlook real and present concerns - from deep fakes to electoral disinformation. Michael Wooldridge is determined to demystify AI and explain how it can improve our lives, in a whole host of different ways. A professor of Computer Science at the University of Oxford, and the director of Foundational AI Research at the Alan Turing Institute, Mike believes the most common fears around this technology are "misplaced". In a special 300th edition of The Life Scientific, recorded in front of an audience at London's Royal Institution (RI), Mike tells Jim al-Khalili how he will use this year's prestigious RI Christmas Lectures to lift the lid on modern AI technology and discuss how far it could go in future. Mike also reminiscences about the days when sending an email was a thrilling novelty, discusses why people love talking to him about the Terminator at parties, and is even challenged to think up a novel future use of AI by ChatGPT.Presenter: Jim al-Khalili Producer: Lucy Taylor Audio editor: Sophie Ormiston Production co-ordinator: Jonathan Harris
How do you solve a problem like CO2? As the curtain closes on the world’s most important climate summit, we talk to a scientist who was at COP 28 and is working to solve our carbon dioxide problem. Professor Mercedes Maroto-Valer thinks saving the planet is still Mission Possible - but key to success is turning excess of the climate-busting gas, carbon dioxide, into something useful. And as Director of the Research Centre for Carbon Solutions at Heriot-Watt University and the UK’s Decarbonisation Champion, she has lots of innovative ideas on how to do this. She also has a great climate-themed suggestion for what you should say when someone asks your age… Presenter: Jim Al-Khalili Producer: Gerry Holt Audio editor: Sophie Ormiston Production Co-ordinator: Jonathan Harris
The Life Scientific zooms in to explore the intricate atomic make-up of metal alloys, with complex crystalline arrangements that can literally make or break structures integral to our everyday lives. Professor Sir Harry Bhadeshia is Professor of Metallurgy at Queen Mary University of London and Emeritus Tata Steel Professor of Metallurgy at the University of Cambridge. He’s been described as a ‘steel innovator’ – developing multiple new alloys with a host of real-world applications, from rail tracks to military armour. Harry’s prolific work in the field has earned him widespread recognition and a Knighthood; but it's not always been an easy ride... From his childhood in Kenya and an enforced move to the UK as a teenager, to the years standing up to those seeking to discredit the new path he was forging in steel research - Jim Al-Khalili discovers that Harry's achievements have required significant determination, as well as hard work. Presenter: Jim Al-Khalili Producer: Lucy Taylor Audio editor: Sophie Ormiston Production Co-ordinator: Jonathan Harris
“Big data” and “data science” are terms we hear more and more these days. The idea that we can use these vast amounts of information to understand and analyse phenomena, and find solutions to problems, is gaining prominence, both in business and academia. Cathie Sudlow, Professor of Neurology and Clinical Epidemiology at the University of Edinburgh, has been at the forefront of enabling health-related research using ever-increasing datasets. She tells presenter Jim Al-Khalili why this type of research matters and how the COVID-19 pandemic changed attitudes towards data in healthcare. Over the course of her career, Cathie has held a variety of roles at different organisations, and she is currently Chief Scientist and Deputy Director at Health Data Research UK. She believes that there is no room for prima donnas in science, and wants her field to be open and collaborative, to have the most impact on patients’ lives.Presenter: Jim Al-Khalili Producer: Florian Bohr Production Co-ordinator: Jonathan Harris
Professor Jim Al-Khalili meets one of Britain's greatest physicists, Sir Michael Berry. His work uncovers 'the arcane in the mundane', revealing the science that underpins phenomena in the world around us such as rainbows, and through his popular science lectures he joyfully explains the role of quantum mechanics in phones, computers and the technology that shapes the modern world. He is famed for the 'Berry phase' which is a key concept in quantum mechanics and one Sir Michael likes to explain through an analogy of holding a cat upside down and dropping it, or parallel parking a car.Presenter: Jim Al-Khalili Studio Producer: Tom Bonnett Audio Editor: Gerry Holt Production Co-ordinator: Jonathan Harris
People around the world are living longer and, on the whole, having fewer children. What does this mean for future populations? Sarah Harper CBE, Professor in Gerontology at the University of Oxford, tells presenter Jim Al-Khalili how it could affect pensions, why it might mean we work for longer, and discusses the ways modern life is changing global attitudes to when we have children, and whether we have them at all. Fertility and ageing have been Sarah's life's work and she tells her story of giving up a career in the media to carry out in-depth research, and going on to study population change in the UK and China, setting up the Oxford Institute of Population Ageing and later becoming a Scientific Advisor to UK Government.Presenter: Jim Al-Khalili Producer: Tom Bonnett Production Co-ordinator: Jonathan Harris
Our primate cousins fascinate us, with their uncanny similarities to us. Studying other apes and monkeys also helps us figure out the evolutionary puzzle of what makes us uniquely human. Sarah Blaffer Hrdy’s work brings a female perspective to this puzzle, correcting sexist stereotypes like the aggressive, philandering male and the coy, passive female. Sarah is professor emerita of anthropology at the University of California, Davis, and studies female primate behaviour to create a richer picture of our evolutionary history, as well as what it means to be a woman or a parent today. Her overarching aim is to understand the human condition, a goal she initially planned to pursue by writing novels. Instead, she found her way into science: her ground-breaking study of infanticide among langur monkeys in northern India overturned assumptions about these monkeys’ murderous motivations. Later in her career, she looked into reproductive and parenting strategies across species. We humans are primed by evolution, she believes, to need a lot of support raising our children. And that is a concern she found reflected in her own life, juggling family commitments with her career ambitions as a field researcher, teacher, and science writer.
The Life Scientific returns with a special episode from the USA; Princeton, New Jersey, to be precise. Here, the Institute for Advanced Study has hosted some of the greatest scientific minds of our time - Einstein was one of its first professors, J. Robert Oppenheimer its longest-serving director - and today's guest counts among them. Edward Witten is professor emeritus at the institute and the physicist behind M-Theory, a leading contender for what is commonly referred to as ‘the theory of everything’, uniting quantum mechanics and Einstein’s theory of gravity. He talks to Jim al-Khalili about a career that’s spanned some of the most exciting periods in modern theoretical physics - and about one particular problem that has obsessed and eluded him since his days as a student.Producer: Lucy Taylor
Exercise in older age is high on the agenda, but the idea that with age comes bags of time and a desire to ‘get out there’ isn’t true for a lot of us. How do you juggle exercise around caring for partners, grandchildren or staying in work? What if you haven’t exercised for years? What can your body take, and how has it changed with age? James Gallagher hears how octogenarian athlete ‘Irongran’ keeps going, he explores the mental and physical barriers that stop us exercising and he finds out what he might feel like in 40 years as he pulls on an ageing suit.(Photo: Elderly man going for a run.

How many hours do you spend sitting down per day? Six? Maybe eight? Or 10? Between commuting, working and relaxing, sitting can soon add up to hours and hours. James Gallagher delves into the science to find out exactly how much sitting is too much; when does it become worrying for our health? James visits a lab to explore what prolonged sitting does to the body and he’ll find out whether there’s anything you can do to offset the effects of sitting a lot. We’ll hear about the origins of sitting research - and just because we like to explore every angle on a topic, we’ll hear all about why standing too much can also be a worry.(Photo: Woman sitting at desk in office.

Can you imagine being able to do fusion at such a complex level that your byproduct would be gold? Philosopher's stone, anyone?

This is either clever, or totally stupid: So, I know the pressure even at the bottom of the Mariana Trench is still ridiculously tiny compared to a star, but I wonder if there would be any benefit to trying to make fusion work there? (obviously, it would not be easy or cheap to operate at the bottom of the ocean, I'm just wondering if there would be qny benefits)

Many plus and minus to this plan. You can't pay off a computer to get what you want. A plus. We've seen how often we face glitches and crashes with machines. Huge minus.

The US, seeing it's post WWII hegemony diminish, is now following in the steps of Rome, engaging in excessive militarism and squandering it's resources on a huge military build up in the Pacific while fighting a futile proxy war with Russia in the Ukraine. Like Rome, it will ultimately be surpassed, most likely by China. All the pathetic anti-Chinese rhetoric in the world, pumped out by US government officials and echoed by the corporate MSM will not change this fact. The Chinese are bigger, older, and smarter over all. Most science PhDs in the US are now awarded to students from abroad. Like Rome in it decline, the US military is made up mainly of poor Black Americans (30%) Hispanics (many not even citizens) and other ethnic minorities. Still, it will take many decades for this scenario to play out. Before that time, we may all be destroyed by the climate change brought about by western excesses and corruption.

I happened to listen to this podcast about the primitive, cannibalistic RCC (Roman Catholic Corporation) Injustices on the SCOTUS overturned Roe. This backward group of theocrats wants to drag America back 250 years to the dark ages of slavery and patriarchy. So Ms. Rubenstein this is not just an intellectual fis agreement between science and religion but a life and death struggle between the forces of light and knowledge (science) and superstition and darkness (religion). This court pretends on religious grounds to be concerned about innocent life and yet it hypocritically promotes gun violence by refusing to allow states to restrict guns. America has become a dystopian freak show run by religious nutters, war mongers, weapons makers, oligarchs and climate destroying fossil fuel corporations.

While this story attempts to cast shade on China's use of AI in facial recognition, especially concerning the awareness of the number of Uighurs in a certain location, the US and UK tolerate the collection of vast amounts of private data by corporations about private citizens. The quaint idea that this is only for commercial purposes was blown up by the use of this data in the 2016 US Presidential election when Facebook sold data to the British company Cambridge Analytica which it used to build up psychological profiles of people sympathetic to Dump's messsge of racial hatred and white supremacy, leading to Dump's election. Are these people totally clueless or just willfully unself aware?
