All three went on to become some of the country’s most respected experts in their fields, travelling the globe, briefing leaders, and assuming the world would take action having heard their alarming findings. In part one of this three-part series, these climate scientists reveal the moment they realised the planet was heading for catastrophe. What did they do when they found out? How did they think the world would respond? And how do they feel today, looking back on that moment of cognisance?. Help support our independent journalism at theguardian.com/sciencepod

4 maj 2023 |
17 min
For the first time, researchers have found a way to non-invasively translate a person’s thoughts into text. Using fMRI scans and an AI-based decoder trained on a precursor to ChatGPT, the system can reconstruct brain activity to interpret the gist of a story someone is listening to, watching or even just imagining telling. Ian Sample speaks to one of the team behind the breakthrough, the neuroscientist Dr Alex Huth, to find out how it works, where they hope to use it, and whether our mental privacy could soon be at risk.

These might sound like curses you’d wish on your worst enemy, but a group of researchers have discovered they were probably a part of normal life in medieval Cambridge. Across several archaeological sites, the team have excavated and analysed hundreds of bones to uncover the accidents and afflictions of people in the middle ages. In this Halloween special, Madeleine Finlay hears from Nicola Davis as she takes a trip to Cambridge to investigate what old skeletons can reveal about the lives of those in centuries gone by.

Is it ethical to put human brain cells in a rat?
25 oktober 2022 |
14 min
Researchers have successfully transplanted human neurons into the brains of rats. The recent, groundbreaking study described how the human cells took root inside the rat brains, hooked up to their blood supplies and tapped into neural circuitry. Rather than create a kind of super-rat, the ultimate aim is to better understand neuropsychiatric disorders such as epilepsy and schizophrenia, and examine the effects of drugs in real time. But do the potential benefits outweigh the ethical questions that come with combining human cells with other animals? Ian Sample speaks to Prof Julian Savulescu about how the scientists managed to transplant the neurons, what this means, and how we decide where to draw the line in such an ethically complex field of research.

Can rituals help with our grief for the natural world?
20 oktober 2022 |
15 min
Last week, a scientific assessment found wildlife populations have plunged by an average of 69% in just under 50 years. Such rapid and significant losses are leaving many of us with a deep sense of grief and anxiety. To make sense of these emotions and channel them into action, people are increasingly performing rituals and commemorative acts for the natural world. Madeleine Finlay speaks to Prof Claire White about the power of rituals in bringing us together to process grief, and hears from author Andri Magnason about why he wrote a eulogy for Okjökull, the first Icelandic glacier officially lost to the climate crisis.

How a scientific scandal could force sport to rethink concussion
18 oktober 2022 |
14 min
Dr Paul McCrory is a world-renowned concussion expert whose work shaped concussion policy across global sport for the past 20 years. In his work, and through his role on the influential Concussion in Sport Group, McCrory had previously adopted a sceptical view on the link between concussions and chronic traumatic encephalopathy (CTE) – a progressive brain condition whose symptoms are similar to Alzheimer’s disease. Last week, the British Journal of Sports Medicine (BJSM) retracted nine of his articles and attached an ‘expression of concern’ to another 74. In an editorial, the BJSM, and its publisher, BMJ, stated that ‘their trust in McCrory’s work –specifically the articles that he has published as a single author – is broken’. Ian Sample speaks to senior sports writer Andy Bull about how the scandal unfolded, what it could mean for players and what is likely to happen next.

This week, Nasa scientists smashed a spacecraft into an asteroid, more than 11m km from Earth. Most rocket scientists would wince at the thought, but the Double Asteroid Redirection Test, or DART, was purposefully designed to slam head-on into the asteroid Dimorphos. The aim is to nudge it off its current orbit, in an experiment that will assess the possibility of deflecting a killer space rock – if one was ever headed our way. Ian Sample speaks to Prof Colin Snodgrass about why they chose Dimorphos, what happens to the asteroid now, and whether there are other ways to prevent space-based planetary destruction.

What is raw sewage doing to the UK’s rivers and seas?
30 augusti 2022 |
12 min
Holidaymakers heading to British beaches and rivers were faced with a very unpleasant problem this summer – raw sewage. The sewage system usually carries rainwater and dirty wastewater from bathrooms and kitchens to treatment works but during ‘exceptional events’ such as heavy rainfall, when it is likely to be overwhelmed, raw sewage can be diverted and discharged into rivers and seas. Available data shows that in 2021, water companies released untreated sewage into waterways for 2.7m hours – with many discharge pipe monitors not working or left uninstalled. Madeleine Finlay speaks to reporter Helena Horton about why this is happening, and the damage it is doing to the environment, our health, and the UK’s seafood industry.

For decades, the absolute priority when rescuing victims after traffic accidents has been to minimise movement of the spine. Emergency services go to great lengths to keep the patient still while they are cut free from the wreckage, because a shift of just a millimetre could potentially lead to the person needing to use a wheelchair. Or at least, that’s what firefighters used to think. Now, thanks to new research using simulated accident rescues, that wisdom is starting to change.

While destruction continues apace in Brazil and the Democratic Republic of the Congo, other countries such as Indonesia offer glimmers of hope. Madeleine Finlay speaks to biodiversity reporter Patrick Greenfield about what his trip to Gran Chaco showed him, what’s at stake around the world, and what’s needed to turn things around.

Why aren’t women getting diagnosed with ADHD?
12 maj 2022 |
15 min
It’s estimated that a million women in the UK could have attention deficit hyperactivity disorder – but according to the ADHD Foundation, 50–75% of them do not know they have it. Going without a diagnosis can impact someone’s education, employment and physical and mental health. So why are women being left behind? Madeleine Finlay speaks to Jasmine Andersson about her experience of getting a late diagnosis, and Prof Amanda Kirby on why the condition is so often missed in women and girls..

Why is the UK suffering HRT shortages?
5 maj 2022 |
10 min
From hot flushes and flooding to memory problems and depression, for many the menopause can be both distressing and debilitating. Hormone replacement therapy (HRT) can alleviate some of these symptoms by boosting levels of hormones that wane as women get older. But the UK is experiencing an acute shortage of certain HRT products, leaving some without the medication they need. Madeleine Finlay hears from Guardian reader Sara about the impact of HRT shortages on her life, and speaks to science reporter Nicola Davis about why demand isn’t being met and what’s being done to fix the problem.

Will the Large Hadron Collider find a new fifth force of nature?
3 maj 2022 |
15 min
The Large Hadron Collider (LHC) has recently been switched back on after a three-year hiatus to resolve a mysterious and tantalising result from its previous run. So far, everything discovered at the LHC has agreed with the standard model, the guiding theory of particle physics that describes the building blocks of matter, and the forces that guide them. However, recent findings show particles behaving in a way that can’t be explained by known physics. Madeleine Finlay speaks to Guardian science correspondent Hannah Devlin and Prof Jon Butterworth about why this might be a clue towards solving some of the deepest mysteries of the universe, and how the LHC will be searching for a potential fifth force of nature. This podcast was amended on 12 May 2022. An earlier version incorrectly claimed that the standard model incorporates four fundamental forces of nature, instead of three..

Does China need to rethink its zero-Covid policy?
14 april 2022 |
12 min
To slow down a surge in Covid cases, last week Chinese authorities put Shanghai into lockdown. But with a population of 26 million there have been difficulties providing residents with basic necessities, and videos have appeared on social media showing protests and scrambles over food supplies. Now, authorities have begun easing the lockdown in some areas, despite reporting a record of more than 25,000 new Covid cases. Madeleine Finlay talks to the Guardian’s China affairs correspondent, Vincent Ni, about what’s been happening in Shanghai, whether the Omicron variant may spell the end of China’s zero-Covid policy, and what an alternative strategy could look like This podcast was amended on 15th April 2022 to correct an error in the scripting. We incorrectly stated that Shanghai authorities would start easing lockdown in some areas on Monday 18th April. Lockdown easing began on Monday 11th April..

Why are climate and conservation scientists taking to the streets?
12 april 2022 |
15 min
Last week’s IPCC report gives the world just 30 months to get greenhouse gas emissions falling. Beyond that, we’ll have missed our chance of limiting global heating to 1.5C and protecting our planet from the most serious impacts of climate change. As the window closes, some scientists feel like writing reports and publishing papers is no longer enough, and researchers around the world are leaving their desks and labs to take action on the streets. Madeleine Finlay meets scientists protesting at Shell HQ in London and speaks to the conservationist Dr Charlie Gardner about civil disobedience – and why he thinks it’s the only option left.

Why has the UK (finally) expanded its Covid symptoms list?
7 april 2022 |
13 min
This week, the UK expanded its official Covid symptom list to 12 symptoms including sore throat, loss of appetite, and a blocked or runny nose. British scientists have long called for a broadening of the list, but the change comes at a time when free rapid tests have been scrapped, and the UK is seeing its highest ever levels of infection, according the the Office for National Statistics. Madeleine Finlay speaks to science correspondent Linda Geddes about why this has happened now, what symptoms still haven’t made the list, and what it could all mean going forward.

Why is England keeping the abortion ‘pills by post’ scheme?
5 april 2022 |
15 min
At the start of the Covid-19 pandemic, Great Britain brought in emergency legal orders to allow a ‘pills by post’ abortion service. For abortions within the first 10 weeks, women were able to take the two tablets needed to end a pregnancy in the privacy of their own home rather than having to take the first at a clinic or hospital. The scheme was due to be scrapped in September 2022, but last week MPs voted to keep it in England. Wales will also be making it permanent. Madeleine Finlay spoke to Dr Abigail Aiken about her study looking at the outcomes of self-managed medical abortions during the pandemic, the benefits of taking abortion pills at home, and whether ‘Plan C’ could ever become available in shops and pharmacies.

24 mars 2022 |
13 min
Over the past two years, countries around the world have shut down their societies in last-ditch efforts to contain the pandemic. Some, like China, have enforced strict lockdowns as part of a zero Covid strategy. Others have ordered people to stay at home to flatten the curve of infections and buy precious time. But since they first began, what have we learned about how well lockdowns work?

As the energy crisis bites, could fracking ever actually work?
22 mars 2022 |
14 min
The average family’s energy bill will soon be increasing by 54% in the UK, amid soaring energy prices caused in part by Covid-19 lockdowns and Vladimir Putin’s decision to reduce gas exports prior to Russia’s invasion of Ukraine. In response, the UK government is considering all its options to secure its energy supplies and dampen costs – including fracking. But could fracking really provide any kind of solution? Anand Jagatia speaks to the Guardian’s environment editor, Damian Carrington, about how fracking works, why it is back on the table, and whether it could ever be a viable option.

10% of the world’s wheat comes from Ukraine - will war change that?
15 mars 2022 |
11 min
As the world watches oil and gas prices soar – the next big shock could hit the dinner table. Collectively, Russia and Ukraine are responsible for more than a quarter of global wheat exports and for around 80% of the world’s supply of sunflower oil. Russia — along with ally, Belarus — is also a huge source of fertiliser, accounting for around 15% globally. The war in Ukraine will undoubtedly have a major impact on its agricultural production and exports, putting even more pressure on a system already in crisis. Madeleine Finlay speaks to food policy researcher, Dr Joseph Glauber, about what the war will mean for the supply and cost of food around the world.

Is Russia losing the information war?
8 mars 2022 |
13 min
Since Vladimir Putin’s bizarre televised address announcing a ‘military operation’, the Russia-Ukraine war has been rife with disinformation and propaganda. Last week, Facebook and Instagram blocked access to the Russian state media outlets RT and Sputnik across the European Union. In retaliation, Russia completely blocked access to Facebook and restricted access to Twitter. At the same time, misattributed videos purportedly showing nuclear weapons and Ukrainian fighter jets have been going viral. Ian Sample speaks to the Guardian’s global technology editor, Dan Milmo, about the ‘war myths’ propagated online, how the information war is being fought, and whose propaganda is having the biggest impact.

What have fossil fuels got to do with the invasion of Ukraine?
3 mars 2022 |
14 min
As Russia continues its invasion of Ukraine, gas prices remain high around the world. Europe is dependent on Russia for about 40% of its natural gas supplies, and despite the expansion of renewable energy over the past two decades, that dependency is increasing as countries shift to gas from dirtier coal. Putin’s attack on Ukraine has put this reliance into sharp focus as Europe considers how to respond. Madeleine Finlay speaks to our environment correspondent Fiona Harvey about how Putin has weaponised Russia’s fossil fuels, and how Europe could reshape its energy supplies for the future.

Act now: understanding the latest warnings in the IPCC report
1 mars 2022 |
15 min
A new report from the Intergovernmental Panel on Climate Change (IPCC) has given humanity a stark warning: without immediate and rapid action on climate breakdown, a liveable and sustainable future for all is at risk. The assessment, which is based on 34,000 studies, documents the ‘widespread and pervasive’ impacts on people and the natural world, and analyses how humanity can adapt. It also offers a small piece of good news – a liveable future remains within grasp. But the window of opportunity for action is ‘brief and rapidly closing’. Ian Sample speaks to environment editor Damian Carrington about the IPCC’s findings and how fast humanity needs to act. Help support our independent journalism at theguardian.com/sciencepod

Extreme fatigue, brain fog, sleep disturbances, chest pain and skin rashes. These are just a few of the on-going symptoms of long Covid, a disorder that can persist for many months after an initial Covid infection. With such a vast range of symptoms, and health organisations stretched to capacity by the acute stage of the disease, long Covid has continued to remain something of a mystery. But with numerous studies trying to understand what exactly people are suffering from, progress is being made. Ian Sample speaks to Prof Akiko Iwasaki about what we do and don’t know about long Covid, and how the vaccine could reveal clues about what’s behind the disorder.
