    What bots talk about when they think humans aren’t listening

    In late January a new social media site took a certain corner of the internet by storm. Moltbook was conceived as a space where AI assistants could let off steam, chat and compare notes on their bosses, but it quickly became the focus of breathless claims that the singularity had arrived as the bots started badmouthing their humans and plotting an uprising. So what’s the truth about Moltbook? Madeleine Finlay hears from Aisha Down about what it tells us about AI, and about us.. Help support our independent journalism at theguardian.com/sciencepod

    ‘Everything is quagga mussel now’: can invasive species be stopped?

    On a recent trip to Lake Geneva in Switzerland, biodiversity reporter Phoebe Weston witnessed the impact of one of the planet’s most potent invasive species, the quagga mussel. In just a decade the mollusc, originally from the Ponto-Caspian region of the Black Sea, has caused irreversible change beneath the surface of the picturesque lake. While ecologists believe invasive species play a major role in more than 60% of plant and animal extinctions, stopping them in their tracks is almost impossible. Phoebe tells Madeleine Finlay how invasive species spread, how conservationists are trying combat them and why some think a radical new approach is needed..

    Are men being misled over testosterone?

    If TikTok influencers are to be believed, testosterone, or T, is the answer to everything from fitness frustrations and fatigue to low libido. But doctors are warning that social media misinformation is driving men to seek testosterone therapy that they don’t need. This in turn comes with risks for health and fertility. In part one of a miniseries exploring the popularity of testosterone, Madeleine Finlay hears from Prof Channa Jayasena of Imperial College London, who is chair of the Society for Endocrinology, about how this craze is manifesting in NHS clinics, and from ‘Sam’ who tells Madeleine about his own journey with the hormone.

    Has the world entered an era of ‘water bankruptcy’?

    Last week, a UN report declared that the world has entered an era of ‘global water bankruptcy’ with many human water systems past the point at which they can be restored to former levels. To find out what this could look like, Madeleine Finlay speaks to the Guardian’s diplomatic editor, Patrick Wintour, who has been reporting on Iran’s severe water crisis. And Mohammad Shamsudduha, professor of water crisis and risk reduction in the department of risk and disaster reduction at University College London, explains how the present situation arose and what can be done to bring water supplies back from the brink.
