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. Rebecca’s book Irritated: The Allergy Epidemic and What We Can Do About It, is out now.. Help support our independent journalism at theguardian.com/sciencepod

Madeleine Finlay sits down with co-host and Guardian science editor Ian Sample to talk through three eye-catching stories from the week, including the news that the number of years people in the UK are spending in good health has declined compared with a decade ago. Also on the agenda is the science, tech and nutrition behind two runners at this weekend’s London marathon breaking the two-hour threshold, and an answer to why some old houses feel particularly spooky.

The transition towards renewable energy received a boost last week when representatives from 57 countries met in Santa Marta, Colombia, for a world-first climate meeting aimed at bringing the fossil fuels era to an end. Madeleine Finlay hears from the Guardian’s global environment editor, Jon Watts, about how the landmark conference came about, who was missing, and whether the optimism can translate into real world action.

Three people have died after an outbreak of hantavirus onboard a cruise ship travelling from Argentina to Cape Verde. The World Health Organization says a total of seven cases – two confirmed by laboratory testing and five suspected – have been identified on the cruise ship so far. It is also investigating whether rare human-to-human transmission of the virus could be behind the cases. Madeleine Finlay talks to Prof Jonathan Ball from Liverpool School of Tropical Medicine to find out where the virus comes from, how it is transmitted to humans, and what health agencies will be doing to try to contain it.

In this episode of Science Quickly, journalist Evan Ratliff joins Kendra Pierre-Louis to discuss his audacious experiment: launching a start‑up staffed entirely by autonomous artificial intelligence agents. Ratliff shares what happened when these agents tried to build a product, manage a human intern, pitch investors and even operate on LinkedIn—sometimes with surprising competence and sometimes with outright fabrication.

Our bodily systems are rife with mutations. In fact, your DNA is mutating right now. These errors, and attempts to repair them, are a key to understanding immune function, aging, and even how heart disease develops. Gene mutations can even mitigate the harm caused by some inherited diseases.
Host Ira Flatow goes on a journey through the illuminating science of genetic mutations with Roxanne Khamsi, science writer and author of “Beyond Inheritance: Our Ever-Mutating Cells and a New Understanding of Health.”
Guest:
Roxanne Khamsi is a science writer and author of the book, “Beyond Inheritance: Our Ever-Mutating Cells and a New Understanding of Health.”

Comparing a backyard sparrow to a fearsome velociraptor seems odd, but modern birds are indeed living dinosaurs. Scientists are finding more and more connections between the past physiology of dinos and the present physiology of birds.
Joining Ira Flatow to talk about some forgotten species from the past tens of millions of years—think gorilla-sized penguins—is Steve Brusatte, paleontologist and author of “The Story of Birds: A New History from their Dinosaur Origins to the Present.”

In mid-April, President Trump issued an executive order to set aside funding and loosen the bureaucratic process at the FDA to fast-track psychedelic therapy research. One obscure psychedelic got a particularly bright spotlight: ibogaine.
Originating from the root bark of the iboga plant of central Africa, the psychedelic has shown promise for curbing opioid addiction and treating PTSD. But it also can be risky to take, and hasn’t made it to the medical mainstream like psilocybin or ketamine. So what’s the story with this drug?
Joining Host Flora Lichtman to talk about its history is neurologist and pharmacologist Deborah Mash, who secured the first FDA approval for clinical trials involving ibogaine in the 1990s. And to tell us how it fits in with the growing interest in medical psychedelics is Jane Hu, journalist for The Microdose newsletter. (Disclosure: Deborah Mash is founder and CEO of a company that’s developing a therapeutic drug based on ibogaine.)
Guests:
Jane C. Hu is a journalist for the psychedelic science newsletter The Microdose, based in Seattle, WA.
Dr. Deborah Mash is professor emeritus of neurology and molecular and cellular pharmacology at the University of Miami School of Medicine. She is the also founder and CEO of DemeRx.

Have you ever seen a flamingo and thought — that can't be a real animal? The colour alone is almost too much. That particular shade of pink, standing in the water, reflected back up from the surface. It looks like something someone painted. But they are real, and in this episode we are going to find out all about them.

Jim Tews is a comedian, Coast Guard veteran, and New York Times bestselling author who’s not shy to talk about ADHD in his stand-up act. Jim shares how he went from doing admin work in the Ohio Coast Guard to community college, where panic attacks finally led to his ADHD diagnosis. Jim shares what it was like trying medication for the first time and why he thinks he wasn’t diagnosed sooner. (“I had girl ADHD.”)
These days, he’s channeling all of it into comedy. With a new special (With Pictures) and album (Without Pictures), Jim talks about how stand-up keeps him grounded and what he’s learned along the way. He also looks back on a childhood full of distractions — like hiding behind doors and watching squirrels — and how those moments still show up in his life and work.

She is set to be the first ever teacher in space. But Christa never makes it to orbit.
In the wake of an unprecedented disaster, questions start to be asked.
Should this mission have been launched in the first place?

Studies detecting microplastics throughout human bodies have made for alarming reading in recent years. But last week, the Guardian’s environment editor, Damian Carrington, reported on major doubts among a group of scientists about how some of this research has been conducted. Damian tells Ian Sample how he first heard about the concerns, why the scientists think the discoveries are probably the result of contamination and false positives, and where it leaves the field. He also reflects on how we should now think about our exposure to microplastics. Help support our independent journalism at theguardian.com/sciencepod

Last week, a UN report declared that the world has entered an era of ‘global water bankruptcy’ with many human water systems past the point at which they can be restored to former levels. To find out what this could look like, Madeleine Finlay speaks to the Guardian’s diplomatic editor, Patrick Wintour, who has been reporting on Iran’s severe water crisis. And Mohammad Shamsudduha, professor of water crisis and risk reduction in the department of risk and disaster reduction at University College London, explains how the present situation arose and what can be done to bring water supplies back from the brink.
