Recent research has suggested a global reproductive crisis could be in the offing, with researchers in Israel saying average sperm counts may have more than halved in the past 40 years. But a study published last month appears to call this narrative into question. Ian Sample is joined by the Guardian’s science correspondent Nicola Davis to unpick why these studies have come to different conclusions – and what could be causing the crisis, if declines are as dramatic as they appear.

Folge vom 27.06.2024The surprising psychology behind extremism, and how politics is driving itPsychologists usually expect ambivalence to be a driver of political apathy. But a new study appears to show a link between ambivalence in our views and the likelihood that we’ll support extremist actions. Madeleine Finlay speaks to the study’s co-author Richard Petty, professor of psychology at Ohio State University, to find out what pushes people to take extreme actions, how politics could be driving this behaviour and how it could be combated.

Folge vom 25.06.2024The infection that affects half of women and its link to antibiotic resistanceAnyone who has had a urinary tract infection knows how agonising they can be. Some infections go away on their own, but many need antibiotics. Beneath the surface of this very common infection lie many mysteries, unanswered questions, and unnecessary suffering. And it gets to the heart of the challenge of tackling antimicrobial resistance. Madeleine Finlay speaks to Dr Jennifer Rohn, head of the centre for urological biology at University College London, about what we now understand about how UTIs take hold, and the complexity surrounding their treatment.
