The surprising value of boring chats, ‘super El Niño’ and Alzheimer’s evidence reviewed

What is a food intolerance, and how do you know if you have one?

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..

Muons, massive waves and restored sight: the winners at the ‘Oscars of science’

Madeleine Finlay sits down with science editor Ian Sample to hear about some of the winners of the Breakthrough Prize, which held its ceremony in LA last weekend. Each prize is worth $3m and they’re awarded in physics, maths and life sciences. Madeleine and Ian hear from molecular biologist Jean Bennett, who shared a life sciences prize for her work developing the world’s first FDA-approved gene augmented therapy for sight loss. She explains how a chance encounter while dissecting a brain in medical school led her on a 25-year journey to develop the treatment..

Mythos: are fears over new AI model panic or PR?

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..

The surprising value of boring chats, ‘super El Niño’ and Alzheimer’s evidence reviewed

Madeleine Finlay sits down with co-host and science editor Ian Sample to discuss three eye-catching stories from the week, including a review into the effectiveness of a new class of Alzheimer’s drug that was once hailed as a game-changer in slowing the progress of the disease. Also on the agenda is the news that the world could be heading for a ‘super El Niño’ this summer and a study exploring whether conversations about dull topics really are as boring as we expect them to be.

Helium: the invisible gas that powers AI, and why it’s in short supply

Alongside the oil and gas stranded in the strait of Hormuz is another commodity vital to today’s economy: helium. It is a critical element in all kinds of areas from MRI machines to the Large Hadron Collider, and even deep-sea diving. It is also integral to the AI boom. And this isn’t the first time its fragile global supply chain has been threatened. So why is helium so useful, and what will happen if the shortage continues? Ian Sample hears from co-host Madeleine Finlay, and from Sophia Hayes, professor of chemistry at Washington University in St. Louis.
