Stateside with Kai and Carter: Stacey Abrams on why gutting of the US Voting Rights Act is ‘evil’

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 [https://www.theguardian.com/sciencepod]

Strange trip: why Trump is backing psychedelics

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.
