Stateside with Kai and Carter: Stacey Abrams on why gutting of the US Voting Rights Act is ‘evil’
16 mei 2026 · 36 min
The US supreme court dealt a devastating blow to the 1965 Voting Rights Act when it ruled in Louisiana v Callais in April that states cannot consider race in redistricting. Southern states from Tennessee to Alabama have rushed to erase majority-Black districts, sparking chaos for the midterm elections. Kai Wright talks to Stacey Abrams, a voting rights activist and former Georgia house minority leader, about the fallout from the decision, and why, despite it all, she still believes the way forward lies in engaging more voters to participate in democracy. ‘They have fractured communities and said we’re going to scatter these seeds. Our job is to grow,’ she says. Help support our independent journalism at theguardian.com/sciencepod Lees meer

Strange trip: why Trump is backing psychedelics
12 mei 2026 · 18 min
Last month President Trump signed an executive order designed to fast track both research and access to psychedelic drugs as treatments for mental health illnesses. The most prominent in the order was ibogaine, a drug derived from the root bark of a West African shrub, that has shown some promise in relieving the long term effects of traumatic brain injury. Madeleine Finlay talks to journalist Mattha Busby about podcaster Joe Rogan’s role in the story, what else is behind the President’s interest in psychedelic research, and what the order will change in practice for scientists and researchers.

28 april 2026 · 18 min
Social media is awash with content about food intolerances and the symptoms to look out for. But figuring out whether you actually have one, and what’s triggering it, is surprisingly difficult. One avenue people are gravitating towards is at-home testing. Madeleine Finlay sits down with health and lifestyle journalist Rebecca Seal to unpick the science behind these tests. Rebecca explains how they purport to work, how accurate they actually are, and how we can all investigate what we might be intolerant to, without breaking the bank.

Mythos: are fears over new AI model panic or PR?
21 april 2026 · 16 min
Earlier this month the AI company Anthropic said it had created a model so powerful that, out of a sense of responsibility, it was not going to release it to the public. Anthropic says the model, Mythos Preview, excels at spotting and exploiting vulnerabilities in software, and could pose a severe risk to economies, public safety and national security. But is this the whole story? Some experts have expressed scepticism about the extent of the model’s capabilities. Ian Sample hears from Aisha Down, a reporter covering artificial intelligence for the Guardian, to find what the decision to limit access to Mythos reveals about Anthropic’s strategy, and whether the model might finally spur more regulation of the industry..

Helium: the invisible gas that powers AI, and why it’s in short supply
14 april 2026 · 16 min
Alongside the oil and gas stranded in the strait of Hormuz is another commodity vital to today’s economy: helium.

Can we eradicate a second human disease?
7 april 2026 · 16 min
The number of human cases of guinea worm, a painful and debilitating tropical illness, fell to a record low of just 10 last year, according to the Carter Centre, the foundation set up by the late former US president Jimmy Carter.

Does going to the moon still matter?
31 maart 2026 · 20 min
If all goes to plan, Artemis II, Nasa’s mission to return humans to the moon, will launch this week. The mission will mark the farthest that humans have travelled from Earth, and the first return to the moon in more than 50 years.

What sets human consciousness apart from AI?
24 maart 2026 · 21 min
Why is it like something to be ourselves and how do physical processes create our subjective experience? These questions get to the heart of the knotty problem of consciousness, and they provided the spark for the latest book from award-winning author and journalist Michael Pollan. In A World Appears, Pollan goes in search of answers about what we do and don’t know about consciousness, and why it has proven such an elusive phenomenon. He tells Ian Sample how thoughts and feelings shape our conscious experience, whether we can learn anything about human consciousness from AI, and why he thinks our minds need to be defended in today’s technology saturated world.

Will China own the green energy future?
5 maart 2026 · 17 min
The conflict in the Middle East has sent energy prices soaring, and for countries that import a high proportion of their fuel, it’s a reminder of the perils of energy dependence. As the recipient of almost 90% of Iran’s crude oil, China knows this only too well. Which partly explains why the country spent the last decade heavily investing in clean power. To find out what else could be driving the strategy, Madeleine Finlay speaks to senior China correspondent Amy Hawkins.

Does Trump want to wage an AI-powered war?
3 maart 2026 · 16 min
In the past three months, Donald Trump’s White House has reportedly used AI twice to effect regime change – once in its capture of Venezuela’s president, Nicolás Maduro, and more recently to help plan the strikes that killed Iran’s supreme leader, Ayatollah Ali Khamenei. The most recent strikes coincided with the end of the Pentagon’s relationship with the AI company Anthropic over concerns its AI tool Claude was being used for purposes the company had explicitly prohibited. The government swiftly signed a new contract with Open AI. To find out what this means for the use of AI in forthcoming conflicts, Madeleine Finlay speaks to technology journalist Chris Stokel-Walker.

Can degrowth save the climate?
26 februari 2026 · 18 min
Since the 1960s, global GDP has been rapidly rising and living standards have reached record highs. But something else has been rocketing up too – carbon emissions. For years, scientists and economists have been asking: is it possible to grow without heating and polluting the Earth? And as the climate becomes more unstable, the issue is only becoming more urgent. Madeleine Finlay hears from two economists arguing for a change in how we measure a country’s success. Nick Stern is professor of economics and government at the London School of Economics and an advocate of green growth, an approach to growth that prioritises green industry. Jason Hickel is a political economist and professor at the Autonomous University of Barcelona who advocates degrowth, shrinking parts of the economy that do not advance our social and ecological goals..
