The collapse of America’s health data system; How sleep affects your focus; Life on Mars in liquid veins?

Episode 329 America’s health data system is in crisis. The US government has been bleeding public health experts – many of whom run crucial public health surveys and databases which help identify, monitor and respond to health threats across the country. From drug use to food security and birth data, discover the 5 surveys most critically hit by the axing of over 20,000 jobs. If nothing is done to address this, vital health information will be missed and the results could be catastrophic. Do you find it difficult to concentrate after a bad night’s sleep? This might be really common, but scientists are still trying to figure out why it happens. A new finding suggests it might have something to do with the brain’s “rinse cycle” – a process where your brain washes away metabolic waste and toxic proteins. Although this usually happens while you sleep, researchers have discovered it may continue in the day if you’re sleep deprived. Life might exist on Mars right now, thanks to a network of liquid water on the Red Planet. Researchers examining Mars’ soil say there’s a good chance tiny veins of liquid water are hiding under the Martian permafrost and that they could support microbial life. This finding has scientists excited, with one suggesting “it’s not impossible that life could exist in the Martian near surface.” Chapters: (00:00) Intro (01:00) The collapse of America’s health data system (08:00) How sleep affects your focus (16:40) Best place to search for life on Mars Hosted by Penny Sarchet and Timothy Revell, with guests Grace Wade, Carissa Wong and Leah Crane.

How mRNA vaccines teach your body to kill cancer; Grim state of climate action; Why birds sing the dawn chorus

Episode 328 Not only has the mRNA covid vaccine saved 14 million lives, it may also help our bodies fight off cancer. A study of cancer patients undergoing immunotherapy treatment showed those who received an mRNA vaccine lived nearly twice as long - and this effect was discovered by accident. In a trial of cancer vaccines, Elias Sayour’s team at the University of Florida used standard mRNA vaccines as a control - they weren’t meant to do anything. Except they did - and the effect was huge. It’s still early days, but as we await more trial results, people are beginning to speculate how this might transform cancer treatment. Ahead of COP30, the World Resources Institute has published the State of Climate Action 2025 report - and it doesn’t make for good reading. It finds that we have failed to meet any of the goals laid out in the Paris agreement to avoid breaching 1.5°C of global warming. From deforestation to coal use, we’re not moving fast enough on anything. Hear from the authors of the report, who offer an important message of hope. Why do birds sing the dawn chorus? Many theories exist - 11 in fact - but a new one has emerged, after scientists were studying zebra finches in the lab. Hear their conclusion while enjoying the serenity of birdsong, recorded at some of the RSPB’s nature reserves. Chapters: (00:00) Intro (00:34) How mRNA vaccines fight cancer (10:00) State of Climate Action report (21:13) Why birds sing the dawn chorus Hosted by Rowan Hooper and Penny Sarchet, with guests Michael Le Page, Clea Schumer and Sophie Boehm.

First climate tipping point triggered; Man controls another person's body by brain implant; health worries over sumo wrestlers

Episode 326 The world’s first major climate tipping point has been triggered. The decimation of warm water coral populations caused by rising temperatures is now irreversible - passing the point of no return. The global consequences of widescale coral dieback could be catastrophic, so experts are sounding the alarm. But is anyone listening? A man with paralysis has telepathically controlled the hands of another person. Keith Thomas is unable to move or feel through his hands. But thanks to a new advancement, using brain and muscle electrodes, he was able to control the hands of a non-paralysed woman using his thoughts alone. Could this one day lead to Avatar-like body control technology? For only the second time in its 1,500-year history, professional Sumo wrestling has left Japan. A Grand Sumo Tournament is being held at London’s Albert Hall, where over 40 elite wrestlers are competing in a five day tournament. Sumo writer John Gunning discusses the physics of sumo, the incredible diets of the wrestlers and the worrying consequences of the sport on their longevity. Chapters: (00:00) Intro (01:34) Coral tipping point (11:23) Avatar brain implant (22:10) The longevity of sumo wrestlers Hosted by Rowan Hooper and Penny Sarchet, with guests Madeleine Cuff, Carissa Wong and John Gunning.

Mice with two dads; perfect your sleep with science; how lizards survived dinosaur-killing asteroid

Ep 309 A groundbreaking experiment in reproductive biology has resulted in mice being born from two biological fathers. By fusing sperm and putting them into an emptied egg cell, researchers in China have produced healthy and fertile offspring from two male mice. While it’s early days and the technique requires hundreds of embryos to get results, it opens up the possibility of same-sex reproduction in mammals, including humans, in the future. New insights into the power of sleep reveal how short naps can boost creativity. A study found that reaching a certain stage of sleep, known as N2, significantly increased people’s chances of having an “aha!” moment. It’s more evidence of how deeply intertwined sleep is with problem-solving and innovation, and why naps might be more productive than we thought. One ancient lizard family managed to survive the asteroid that killed the dinosaurs, and they’re still around today! Scientists have traced the lineage of night lizards back to over 90 million years ago. Their ability to shelter underground and survive on little energy may have helped them live through one of Earth’s biggest disasters. Chapters: (00:38) Same-sex reproduction breakthrough (12:09) Power naps and creativity (22:37) Ancient lizard survives dinosaur-killing asteroid Hosted by Rowan Hooper, Penny Sarchet, and Michael Le Page.

How Jane Goodall changed the world; How the universe ends; How “selfish sperm” affect male fertility

Episode 324 The legendary primatologist Jane Goodall died last week aged 91, leaving behind a remarkable legacy. Her work studying tool use in chimpanzees completely reshaped the way we view animal intelligence. Fiercely protective of the natural world, she was also responsible for a huge amount of advocacy during her life. Primatologist Alejandra Pascual-Garrido worked directly with Jane and shares the story of her life and work. Will the universe end with a bang, or a quiet whimper? Katie Mack is a cosmologist, science communicator and best-selling author of The End of Everything. She explores why she’s fascinated by how the universe might end, the most likely scenarios for how it happens and why it’s an exciting time for both physics and cosmology. She also offers her thoughts on the recently announced Nobel Prize in Physics - and teases her upcoming book How To Build A Universe. Older fathers may have a bigger impact on the health of their offspring than we realised. We know that sperm accumulates mutations as men age, but a study sheds new light on the risks. Men aged 70 are twice as likely to have children with serious genetic disorders. And it’s all to do with “selfish sperm”. Chapters: (00:51) Jane Goodall’s legacy (20:52) Kate Mack on the end of the universe (38:47) Selfish sperm Hosted by Rowan Hooper and Penny Sarchet, with guests Alejandra Pascual-Garrido, Katie Mack and Michael Le Page.

Emergency in Antarctica; How movement changes the brain; Why women live longer than men

Episode 323 Temperatures in Antarctica have soared by over 35°C. Scientists are concerned about how quickly things are changing on the continent as these warmer temperatures impact the polar vortex. Coupled with record lows in sea ice cover over the last decade, this could be a sign that Antarctic weather patterns have shifted permanently. What’s driving this change - and what happens if we have reached a tipping point of no return? Many mammals, including cats, can pivot their ears to focus on a particular sound. But our ears aren’t quite so flexible. But now it appears that a similar process happens inside our brain - ‘swivelling’ to focus on sounds from different directions. This has only recently been discovered thanks to new portable EEG equipment, as the process only happens when we’re moving. This finding may help us better understand how movement changes the brain - and could even help improve hearing aids. Why do women tend to live longer than men? It could have something to do with the very chromosomes that determine biological sex. By looking at birds, whose sex chromosomes differ from those of mammals, researchers have discovered an intriguing hint at what’s going on. But does their new hypothesis hold up? Alongside all the emerging science, Rowan shares his own theory. And the team discusses the disappearance of the Y chromosome - and what that really means for men. Chapters: (00:00) Intro (01:04) Emergency in Antarctica (10:46) How movement changes the brain (19:34) Why women live longer than men Hosted by Rowan Hooper and Penny Sarchet, with guests Madeleine Cuff, Edward Doddridge, Caroline Williams and Sam Wong.

First brain engineering in a mammal; landmark in fossil fuel lawsuits, the legacy of Pope Francis

Episode 300 The first genetically engineered synapses have been implanted in a mammal’s brain. Chemical brain signals have been bypassed in the brains of mice and replaced with electrical signals, changing their behaviour in incredible ways. Not only did they become more sociable, they were also less anxious and exhibited fewer OCD-like symptoms. This work has sparked hope that one day we could use this technology to help humans with mental health conditions. But would you want someone making permanent edits to your brain? For the first time, climate scientists can now link specific fossil fuel companies to climate-related economic damages in particular places. A new method has been developed that can show the exact impact these companies are having on our environment - which the world’s top five emitters linked to trillions of dollars of economic losses. Find out how scientists have managed to piece this together - and whether these companies are about to face massive lawsuits. As we reflect on the death of Pope Francis, we explore his legacy on scientific issues and his transformative stance on climate change. As the spiritual leader of 1.4 billion Catholics, he became an influential figure in advocating for better care to be taken of our planet. Will his legacy continue with the next Pope? Chapters: (00:28) First brain engineering in a mammal (10:57) Landmark in fossil fuel lawsuits (19:33) Climate legacy of Pope Francis Hosted by Rowan Hooper and Penny Sarchet, with guests Alexandra Thompson, James Dinneen, William Schafer, Chris Callahan, Justin Mankin and Miles Pattenden.

The evolutionary price we pay for longer lives; the asteroid coming VERY close to Earth; how dinosaurs shaped the ecosystem

Episode 321 Humans live a lot longer than other primates - and much of that is down to our immune system. But there’s a price we pay for the capacity to fight off infections: inflammation. Chronic inflammation is to blame for a range of health issues, especially those related to older age. And now research has revealed exactly why inflammation is good for longevity but bad for health. Find out how proteins called death-fold domains often malfunction - and what this could mean for the future of drug development. Bigger than the Eiffel Tower and closer than the moon - the asteroid Apophis will skim past Earth in 2029 and will be visible to the naked eye. Don’t worry, astronomers assure us it will NOT hit us. But it could be a good testbed for NASA’s asteroid deflection technology, helping us to prepare for more dangerous space rocks in the future. With two major space agencies due to visit Apophis - what will we find? If you thought there was nothing new to learn about the extinction of the dinosaurs, think again. Something we hadn’t yet considered was the impact dinosaurs had on the ecosystem. Given they were so massive, dinosaurs made wide-ranging changes to the planet’s landscapes, such as shifting rivers. So when they were wiped out, there were huge knock-on effects, which researchers have now been examining.
