Episode notes
Scientists have long referred to the Goldilocks zone – the region around a star where conditions are not too hot and not too cold but “just right” for life. Joined by a live audience at the Cheltenham Science Festival in the UK, Tom Whipple asks what are the true limitations of alien life? How do we spot it? And have we been looking too narrowly? Planetary scientist at MIT Sara Seagar discusses her team’s mission to Venus where, on the surface, temperatures can reach 500 degrees Celsius and it rains sulphuric acid. Above the rain, up in the clouds, Sara Seagar tells us how there could be…

The quest for dark matter
The quest for Dark Matter just got interesting. Researchers on an international project called the Lux-Zeplin (LZ) Dark Matter Experiment reported they may have discovered the signature of a bit of Dark Matter passing through an underground mine in South Dakota. Kimberly Palladino, professor of physics at Oxford and a member of that LZ collaboration, speaks to Roland Pease to explain how dark matter is being detected. Probiotics have long been all the rage in health advice, but this week we discovered they may also be good for corals. Microbiologist turned ecologist Erika Santoro has been…

The day of the datacentres
Reports about the impacts of datacentres, including carbon emissions, water usage and power consumption, vary drastically and the truth can be hard to decipher. Deborah Andrews, Emeritus Professor at London South Bank University, joins us for some myth busting. Plus, science journalist Caroline Steel has been scouring the journals and brings us some of this week’s most exciting science news, including the failed attempts to save the Swift space telescope. Presenter: Tom Whipple Producers: Alex Mansfield, Katie Tomsett, Keiran Manetta-Jones Editor: Ilan Goodman Production Co-ordinator: Jana…

Is the era of the cancer vaccine upon us?
This week Merck (known as MSD in Europe) and Moderna announced that a personalised cancer vaccine had significantly improved the outcomes of melanoma patients. Is the era of the cancer vaccine, at last, upon us? What does that mean? Anne Willis, a cancer cell biologist at the Medical Research Council, joins us to discuss. In just a few weeks the Royal Society will be putting out the red carpet as the most coveted prize in non-fiction science is about to be awarded. We will be speaking weekly to the shortlisted authors for the Royal Society Trivedi Book Prize, and we are starting with Kit…

Should we be scared of AI viruses?
The extreme possibilities of synthetic biology hit the headlines last week, when researchers at Stanford University in the US announced they had created new kinds of viruses designed by Artificial Intelligence. Roland Pease is joined by microbiologist Dr Simon Clarke from Reading University and Joy Zhang, Professor of Sociology at the University of Kent, to discuss whether we should be concerned about the prospect of AI viruses. Meanwhile, 50 years ago NASA's remarkable Viking space probes touched down on Mars, breaking new frontiers in space science. Claire Cousins, part of the European…

The state of our substrate: What is drought doing to our soil?
Large parts of Europe are in the grip of drought. According to the UK Meteorological Office, last week was the UK's driest July on record. Katie Field, professor of plant-soil processes at Sheffield University, joins us to discuss the state of our struggling substrate. Next week, a dramatic solar eclipse will be sweeping down the Atlantic. In the past, eclipses have been vital to astronomers exploring the outer reaches of the Sun. Now though, they can make their own on demand. Esther Bastida-Pertegaz, project engineer at the European Space Agency, discusses the flying formation Proba-3…

Testing testosterone testing
Secretary of Defence Pete Hegseth has announced that the US military will be screening military personnel aged 30 and older for testosterone deficiency. Those found with low testosterone levels will be offered voluntary hormone replacement therapy. The secretary says this is to ensure “a healthy, capable, and decisively dominant fighting force”. Tom Whipple is joined by Professor Joe Herbert from the University of Cambridge to discuss why jacking soldiers up with testosterone may or may not be the best idea. Marine Biologist Kathryn Ayres, from the non-profit organisation Beneath the Waves,…

How might we spot nukes in space?
A few years ago a satellite speeding through the Van Allen belt in earth orbit raised concerns that it may include a nuclear weapon. An explosion in that orbit would take out much of our global space infrastructure. The Outer Space Treaty of 1967 specifically prohibits such a thing, but it has proven technologically impossible to verify and monitor over the decades. Tom Whipple is joined by Prof Areg Danagoulian, Associate Professor of Nuclear Science and Engineering at MIT to explore a clever concept to spot such a thermonuclear device in orbit that he has published in this month’s Nature…

Are we one step closer to creating life in a lab?
Synthetic biologist Kate Adamal and her team at the University of Minnesota published their research into the lab-created ‘SpudCell’ in a significant step towards building life from scratch. Science journalist, Kai Kupferschmidt, joins us to discuss the implications of this research, as well as the controversies. Nature reporter Lizzie Gibney tells us how science has helped us better understand the route that the famous Carthaginian general, Hannibal – and not forgetting his elephants – took across the Alps. Plus, in this week’s scout of science stories behind the ‘beautiful game’ we learn…

How do you immortalise natural history?
During this year’s visit to the Royal Society Summer Science Exhibition in London, Tom Whipple discovers how sea urchins are being used to develop techniques to digitally preserve natural history, why we haven’t got robot butlers just yet, and what it takes to bottle lightning. Plus, in his ongoing quest to assemble a World Cup squad of science Tom recruits health reporter James Gallagher to scout out the best football science from around the world. This week, we want to know if there is robust evidence for a home advantage. We speak with Associate Professor of Cell & Developmental Biology…

Can we engineer ourselves out of a heatwave?
As the UK and Europe battles with extreme weather warnings, is it time for us to consider some more extreme tactics to tackle the heat? Tom Whipple is joined by Mark Maslin, Professor of Earth System Science at University College London, to explore if solar geoengineering can help. Also on the show, science journalist Lizzie Gibney discusses the "Salah effect", when exposure to celebrities from stigmatised groups can help increase tolerance. She also examines new research into how the atom nucleus contain energy which can be used for telling the time. Plus, how laughter in great apes may…
