Episode notes
Ever since the earliest known recording of whale song was made in 1949, researchers have been captivated by the wails, rumbles, clicks, grunts and squeals of their communication. As technology improves, scientists are decoding the intricate patterns that make different species’ vocalisations distinctive. Madeleine Finlay hears from Emma Bryce, a journalist who has spent months investigating human efforts to understand whale song. She explains how this knowledge could help us better protect whales from human-made harms. Credits: 1. Copyright 1978 National Geographic Society and 1977 Capitol…

Are rich people really worse behaved? Here’s the science
Who’s more likely to steal sweets from a child? According to science, it’s the rich. A study seemingly confirming our suspicions about the moral behaviour of the wealthy was one of the winners of the 2026 Ig Nobel prizes, which honour research that makes you laugh and then think. Science editor Ian Sample tells Madeleine Finlay what the researchers think could be behind the phenomenon, and they explore some of the other awards, including one for a surprising quality we look for in our friends and another for a biomechanical definition of kissing.

There’s a quick way to slow climate change. Why isn’t everyone doing it?
Methane is a potent greenhouse gas that traps more than 80 times as much heat than carbon dioxide over a 20-year period and causes 25% of global heating today. We definitely don’t want this gas spewing needlessly into the atmosphere, but in 2023 that’s exactly what environment editor Damian Carrington found was happening when he reported on 1,000 super-emitting methane leaks across the globe. Now Turkmenistan, the worst country for mega-leaks, has begun to plug them. Damian tells Madeleine Finlay why some experts call stopping leaks the climate ‘emergency brake’ and reveals which countries…

Everyone hates datacentres. Do we really need them?
AI companies have promised us world-shifting technology. But there’s a cost: loud, unsightly datacentres that drain environmental resources. As the government pushes their rapid growth, can local communities do anything to push back? Madeleine Finlay speaks to the Guardian’s global technology reporter Aisha Down about the backlash to datacentres across the UK and around the world.

Creatine: is there truth behind the hype?
Creatine has become the go-to supplement for anyone wanting to give their fitness a boost and build muscle. It’s even made it out of the gym, with influencers touting its cognitive benefits. But what’s the science behind creatine, and does the evidence stack up? Madeleine Finlay hears from science editor Ian Sample and Dr Justin Roberts, professor of nutritional physiology at Anglia Ruskin University.

It’s finally raining. Will it be enough to end the drought?
After a summer that has seen England and Wales experience the driest July since records began, rain is finally on the horizon. But with reservoirs at ‘exceptionally low’ levels, will there be enough rain to replenish stocks? Madeleine Finlay hears from Dr Anna Murgatroyd, a lecturer in hydrology at Newcastle University, about how much rain we need to see us through next summer, why we’re now at increased risk of floods, and what we can all be doing to take better care of our water supplies.

Today in Focus: Should we be worried about a plague outbreak?
Several hospitals in eastern Russia are under quarantine after a lab worker fell ill at a plague research centre following a reported accident and died. Russia’s health watchdog has said Darya Shipilova, 28, died of ‘pneumonia of unknown aetiology’, but there is speculation about a possible plague infection. Science Weekly co-host Madeleine Finlay tells Lucy Hough, the host of Today in Focus: The Latest, how concerned we should be.

Narcolepsy: why you’ve been thinking about it all wrong
The sleep disorder has been the butt of jokes and a comedic plot point, but the reality of living with narcolepsy is anything but funny. Things could be about to change for people with the condition though, after the US Food and Drug Administration (FDA) approved the first ever drug to treat narcolepsy itself, rather than just its symptoms. Madeleine Finlay tells Ian Sample how the scientific breakthrough came about, and Julie Flygare, who has narcolepsy and founded the non-profit Project Sleep, explains what it is like to live with the condition and how the drug could be gamechanger.

The incredible science of memory manipulation
Madeleine Finlay hears from Steve Ramirez, an associate professor of psychological and brain sciences at Boston University, whose book How to Change a Memory was shortlisted for this year’s Royal Society Trivedi science book prize. He explains how scientists have been able to locate memories in the brains of rodents, trigger them artificially and even remove them, and reveals what the practical applications of this science could one day be for humans..
