Gemma Arterton’s latest acting role is in a play called Walden. It's on in London’s West End and it's the story of estranged twin sisters: one's a botanist for Nasa and the other's a former architect for Nasa. They meet up in a remote cabin in the woods sometime in the future, when the earth’s situation is looking bleak.We take a look at some of claims made yesterday by Dominic Cummings about care homes with Gisella Casciello Rogers whose 85 year old father died in one last year. And we also have Helen Wildbore from The Relatives and Residents Association. Prof Catherine Heymans, astrophysicist and world-leading expert in the so-called dark universe, is now the Astronomer Royal of Scotland. She's the first woman to hold this prestigious role, but the problem is she's still not entirely convinced she should have the job. She suffers from impostor syndrome, but we know she shouldn't! She talks to Emma about challenging the status quo and dealing with aggressive criticism.And we have Annie Macmanus (formerly known as Annie Mac, the DJ) and Esther Freud talking about their new novels which have common themes: motherhood and the risk of losing yourself.
