  • Can the climate survive AI’s thirst for energy?

    Can the climate survive AI’s thirst for energy?
    Jul 16 2024
    Artificial intelligence companies have lofty ambitions for what the technology could achieve, from curing diseases to eliminating poverty. But the energy required to power these innovations is threatening critical environmental targets. Madeleine Finlay hears from the Guardian’s energy correspondent, Jillian Ambrose, and UK technology editor, Alex Hern, to find out how big AI’s energy problem is, and whether it can be solved before it is too late.

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

    ‘Lesbian’ seagulls and ‘gay’ rams: the endless sexual diversity of nature
    Jul 11 2024
    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?

    ZOE and personalised nutrition: does the evidence on glucose tracking add up?
    Jul 9 2024
    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.
