After more than a decade of global consultation, polycystic ovary syndrome – which affects as many as one in eight women – has been renamed. The condition is caused by high levels of androgens, which can lead to symptoms such as excess hair, weight gain and irregular periods. To understand why campaigners wanted it renamed, and what its new name – polyendocrine metabolic ovarian syndrome (PMOS) – could mean for patients, Madeleine Finlay hears from the Guardian’s science correspondent, Nicola Davis, and Rachel, a campaigner from the charity Verity.

An outbreak of Ebola has emerged in the Democratic Republic of Congo and Uganda, leading to nearly 400 confirmed cases and more than 100 deaths.

The US supreme court dealt a devastating blow to the 1965 Voting Rights Act when it ruled in Louisiana v Callais in April that states cannot consider race in redistricting. Southern states from Tennessee to Alabama have rushed to erase majority-Black districts, sparking chaos for the midterm elections. Kai Wright talks to Stacey Abrams, a voting rights activist and former Georgia house minority leader, about the fallout from the decision, and why, despite it all, she still believes the way forward lies in engaging more voters to participate in democracy. ‘They have fractured communities and said we’re going to scatter these seeds. Our job is to grow,’ she says. Help support our independent journalism at theguardian.com/sciencepod

Madeleine Finlay sits down with co-host and science editor Ian Sample to discuss three eyecatching stories from the week, including an update on hantavirus. Also on the agenda is the Pentagon’s release of a tranche of never before seen documents relating to UFOs, and a study looking at the link between taking part in cultural activities and slower biological ageing.

Last month President Trump signed an executive order designed to fast track both research and access to psychedelic drugs as treatments for mental health illnesses. The most prominent in the order was ibogaine, a drug derived from the root bark of a West African shrub, that has shown some promise in relieving the long term effects of traumatic brain injury. Madeleine Finlay talks to journalist Mattha Busby about podcaster Joe Rogan’s role in the story, what else is behind the President’s interest in psychedelic research, and what the order will change in practice for scientists and researchers.
