Revisited: the endless sexual diversity of nature

In this episode from July, Ian Sample talks to Josh Davis, a science writer at the Natural History Museum in London and author of the book A Little Gay Natural History. A study published in June 2024 suggested that, although animal scientists widely observe same-sex sexual behaviour in primates and other mammals, they seldom publish about it. Josh considers why this might be and describes some of his favourite examples of sexual diversity from the animal kingdom.. Help support our independent journalism at theguardian.com/sciencepod

Revisited: are the world’s oldest people really that old?

In this episode from September, Madeleine Finlay speaks to Dr Saul Newman, an interdisciplinary researcher at University College London and the University of Oxford, who has recently won an Ig Nobel prize – given to scientific research that ‘first makes people laugh, and then makes them think’ – for his work showing that many claims of people living extraordinarily long lives come from places with short lifespans, no birth certificates, and where clerical errors and pension fraud abound.

‘Soft and calorie dense’: Chris van Tulleken on how ultra-processed foods keep us hooked

Dr Chris van Tulleken has been at the forefront of the campaign to change our food system and better regulate the sale of ultra-processed foods (UPF). This year he will be giving the Royal Institution Christmas lectures, Britain’s most prestigious public science lectures, in which he’ll be investigating how food has fundamentally shaped human evolution, the importance of our microbiome – as the extra ‘organ’ we didn’t know we had – and how we can all eat better in future, for the sake of our own health and the health of the planet. Nicola Davis sat down with Van Tulleken to discuss the lectures, the challenge of understanding the impact of UPFs on our health, and his top tip for Christmas dinner. Madeleine Finlay hears from them both in this Christmas special edition of Science Weekly. Help support our independent journalism at theguardian.com/sciencepod

Is our model of the universe wrong?

For the past 10 years cosmologists have been left scratching their heads over why two methods for measuring the universe’s rate of expansion provide totally different results. There are two possible solutions to the puzzle, known as the Hubble tension: either something is wrong with the measurements or something is wrong with our model of the universe. It was hoped that observations from the James Webb space telescope might shed some light on the problem, but instead results published last week have continued to muddy the waters. To understand why the expansion rate of the universe remains a mystery, and what might be needed to finally pin it down, Madeleine Finlay speaks to Catherine Heymans, the astronomer royal for Scotland and a professor of astrophysics at the University of Edinburgh.

Does Google’s ‘mindboggling’ new chip bring quantum computers any closer?

On Monday Google unveiled its Willow quantum computing chip. The new chip takes just five minutes to complete tasks that would take 10 septillion years for some of the world’s fastest conventional computers to complete. But despite its impressive power, it’s not clear the chip has any practical applications. So does it bring quantum computing any closer? To find out Ian Sample speaks to Winfried Hensinger, professor of quantum technologies at the University of Sussex. Because of industrial action taking place by members of the National Union of Journalists at the Guardian and Observer this week, you may notice some disruption to the availability of new episodes in your Guardian podcast feeds in the coming days. All the work on this episode was done before the strike action began. For more information please head to theguardian.com. Help support our independent journalism at theguardian.com/sciencepod

S2024!!!

The guardian science is one of the best podcasts out there. They’re pretty short, well written, detail and character, they make science come alive, and they also tackled some of the biggest challenges of our world today – aging, the environment, climate, food and agriculture,sustainability and technology, the brain, etc. The journey with our thoughtful and it’s clear they worked really hard. You should definitely drive!

So sad, yet not surprised, about the global decline in the sounds, the bird call etc, the Biophony of the woodlands. And so glad to have learned the word and its meaning, and the impact human activity has had on the natural world.
