Summer picks: the science of ‘weird shit’

The psychologist Chris French has spent decades studying paranormal claims and mysterious experiences, from seemingly impossible coincidences to paintings that purportedly predict the future. In this episode from April 2024, Ian Sample sits down with French to explore why so many of us believe in what he terms ‘weird shit’, and what we can learn from understanding why we are drawn to mysterious and mystic phenomena.

Summer picks: what does the science say about birth order and personality?

We all know the cliches about older siblings being responsible, younger ones creative, and middle children being peacemakers. But is there any evidence our position in the family affects our personality? In this episode from March 2024, Madeleine Finlay meets Dr Julia Rohrer, a personality psychologist at the University of Leipzig, to unpick the science behind birth order.

What’s happened to all the butterflies?

Butterfly numbers in the UK appear to be at the lowest on record after a wet spring and summer dampened their chances of mating. This comes on top of a long and worrying trend of decline. To find out what’s going on and what we can all do to help butterflies cope with extreme weather patterns, Phoebe Weston speaks to Dr Richard Fox, the head of science for the charity Butterfly Conservation, and to Matthew Hayes, who is part of the Banking on Butterflies project, a collaboration between the Insect Ecology Group at the zoology department in Cambridge University and the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire.

Just how bad is alcohol for us?

For the regular drinker it is a source of great comfort: the fat pile of studies that say a daily tipple is better for a longer life than avoiding alcohol completely. But a new analysis challenges that thinking and says it was based on flawed research that compares drinkers with people who are sick and sober. Madeleine Finlay hears from the study’s lead author, Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research at the University of Victoria, to find out why scientists (including him) were so convinced, and what the actual risks of alcohol are.

George Monbiot on the record jail terms given to Just Stop Oil activists

Last week, five supporters of the Just Stop Oil climate campaign who conspired to cause gridlock on London’s orbital motorway were sentenced to lengthy jail terms by a judge who told them they had ‘crossed the line from concerned campaigner to fanatic’. Columnist and campaigner George Monbiot tells Ian Sample why the sentences are so significant, how they fit into a crackdown on protest in the UK in recent years, and what impact they could have on future climate activism in the UK.

Is there any point in taking multivitamins?

Multivitamins are cheap, convenient, and provide a little bit of reassurance if our diet isn’t quite as healthy as we’d like. But a recent study of nearly 400,000 people spanning 20 years found they didn’t help users live longer, and in fact appeared to show a 4% increased mortality risk. Ian Sample hears from JoAnn Manson, a professor of medicine at Harvard Medical School, to find out what the evidence tells us about the overall health benefits of multivitamins, and how consumers can navigate this large and sometimes confusing market.

‘Lesbian’ seagulls and ‘gay’ rams: the endless sexual diversity of nature

Same-sex sexual behaviours have been reported in a wide variety of species, and a new study suggests that, although animal scientists widely observe it, they seldom publish about same-sex sexual behaviour in primates and other mammals. To find out why and to hear about some of the examples of sexual diversity from the animal kingdom, Ian Sample hears from Josh Davis, a science writer at the Natural History Museum in London and author of the book A Little Gay Natural History.

ZOE and personalised nutrition: does the evidence on glucose tracking add up?

You might have noticed that everyone has recently become a bit obsessed with blood sugar, or glucose. Wellness firms such as ZOE here in the UK – as well as Nutrisense, Levels and Signos – claim to offer insights into how our bodies process food based on monitoring our blood glucose, among other things. But many researchers have begun to question the science behind this. To find out what we know about blood glucose levels and our health, and whether the science is nailed down on personalised nutrition, Ian Sample hears from philosopher Julian Baggini, academic dietician Dr Nicola Guess of Oxford University and ZOE’s chief scientist, and associate professor at Kings College London, Dr Sarah Berry.
