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.

Everything you need to know about Artemis II so far

This week Artemis II’s four-astronaut crew broke Apollo 13’s distance record, becoming the humans to travel the farthest from Earth. Now on their way home, the team has experienced tech malfunctions, views like no other and moments of intense emotion, all in under 10 days. To find out about all the highs and lows of the mission, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample. Help support our independent journalism at theguardian.com/sciencepod

Can we eradicate a second human disease?

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. But despite years-long declines, it remains almost impossible to completely eradicate the parasite. Only one human illness has been entirely eradicated: smallpox. Why is it so difficult, and could guinea worm one day be the second? Ian Sample hears from co-host Madeleine Finlay, and David Molyneux, emeritus professor of tropical disease microbiology at the Liverpool School of Tropical Medicine.

Sauna and cold plunge: where does the evidence stand?

Saunas and cold plunge pools are popping up everywhere in the UK, bringing fiery heat and icy cold to a beach, city farm or park near you. Their users will be ready with all the reasons why it’s good for both the mind and the body. But what’s the evidence for the benefits of sauna and cold plunge? Madeleine Finlay hears from Ian Sample and from Dr Heather Massey, associate professor at the University of Portsmouth’s extreme environments laboratory..

Does going to the moon still matter?

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. It will also pave the way for landing on the moon again as soon as 2028. But given the Apollo missions have already achieved that feat, does going back to the moon still matter today? To find out, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample, the Atlantic journalist Ross Andersen, and Jan Wörner, a former director general of the European Space Agency.

Transporting the most expensive and volatile substance on Earth

A box the size of a filing cabinet was lifted by crane, slowly moved and placed very carefully in the back of an unassuming lorry earlier this week. What looked like a casual drive around the Cern campus was actually a world-first experiment in transporting antimatter, the most expensive and volatile substance on Earth. To find out why scientists wanted to achieve this milestone, and what happened on the journey, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample, and the Cern physicist Dr Christian Smorra..

Terrible decision to use a fame-seeker’s name in episode title

13/11/2025

etherdog

Generally Science Weekly is held in the highest regard but someone messed up massively by including the name of a notorious fame-seeker (KK) in the episode title. Everyone responsible should be sacked or held accountable for the egregious breach of trust.

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!
Science Weekly is excellent !

Biophony

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.
