<description>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.

<description>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.

<description>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.

<description>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.
