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.”

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.

Neuroscience of reality; Quest for dark matter; Folklore of geoscience (New Scientist Live Special)
Episode 327
A special episode recorded on October 18 at New Scientist Live in London, featuring experts in geoscience, dark matter and neuroscience.
Anjana Khatwa is an Earth scientist and TV presenter. In her new book, The Whispers of Rock, she brings together Western scientific knowledge about the evolution of our Earth and indigenous knowledge and stories. She demonstrates this connection by exploring the volcanic formation of the Hawaiian islands, and the fascinating folklore attached to their origin.
Chamkaur Ghag is a Professor of Physics at University College London and an expert on dark matter. He discusses the LZ Dark Matter Experiment, which is operating one mile under the Black Hills of South Dakota, in the search for a signal of this illusive particle.
Daniel Yon is a psychologist and neuroscientist at Birkbeck, University of London. He explains how your brain influences your perception of reality - and how particular neurochemicals in the brain control our willingness to change, or to believe in a conspiracy theory.
Hosted by Rowan Hooper and Penny Sarchet on the Engage Stage at the Excel Centre.

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.

Space 2075: How Humanity Will Live, Work and Make Drugs off-planet | Live Recording at the Royal Society
A special episode all about the future of space exploration, recorded in front of a live audience at the Royal Society in London.
Earlier this year, the Royal Society published ‘The Space: 2075 report’, which recognises the huge changes we’re seeing in space exploration, and urges for action to be taken to make sure the next 50 years of activity in space is sustainable and benefits all of humanity. We brought together a panel of space experts to discuss the accelerated advances we’re seeing.
Helen Sharman, the first British astronaut, blasted off Earth on a Soyuz rocket in 1991. She explains what it’s like to journey into space, the various ways it impacts the body and why humans still have the edge over robots for certain missions.
Irene Di Giulio is a Biomedical Engineer at King's College London. She explores her work helping to get the first disabled astronaut to space and why it’s critical we push towards making space flight accessible.
And Katie King is Co-Founder and CEO of BioOrbit, a pharmaceutical company which plans to make drugs in space. Discover why space is the perfect place to create drugs - potentially bringing at-home cancer treatments to the market.
Hosted by Rowan Hooper and Abby Beall.
