   Is collagen all hype?

   Collagen powders, gummies and pills have boomed in popularity in recent years boosted by claims that they smooth wrinkles, promote glossy hair and help with joint pain. Amid the noise it can be hard to figure out whether there’s any actual science behind the promise of looking younger for longer. Luckily Dr Xand van Tulleken has spent the past three years writing Make me well: a quest to understand the confusing world of wellness, and his chapter on collagen dives deep into the evidence. He tells Madeleine Finlay what collagen does in the body, how we can get it without splashing out on…

   ‘One of the biggest discoveries in science’: have scientists found dark matter?

   For decades physicists have been puzzling over the enigma of dark matter. We think it makes up 85% of the matter in the universe, but the mysterious substance cannot be seen or detected, and we know about it mainly through observations of the gravitational effects it has on other things. But now scientists believe they may be a step closer to detecting it. Science editor Ian Sample explains to Madeleine Finlay why, if confirmed, the finding could completely transform our understanding of the universe. And Dr Samuel Eriksen, senior research associate at the University of Bristol, and first…

   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…

   Could humans ever communicate with whales?

   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…

   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..
