Last week more than 400 scientists signed an open letter to political parties urging ambitious action on the environment to prevent making Britain and the world ‘more dangerous and insecure’. Now that the main parties’ manifestos have all been released, Ian Sample is joined by the global environment editor, Jon Watts, and the biodiversity reporter, Phoebe Weston, to find out what the manifestos have to say about nature and climate, and whether anyone is promising the level of action scientists are asking for.

Here in the UK talking about the weather is already a national pastime, but this month the water-cooler weather chat has ramped up a notch as rain, grey skies and biting temperatures have put summer firmly on hold. Ian Sample talks to Matt Patterson, a postdoctoral research scientist in the Department of Meteorology at the University of Reading, to find out what’s causing the chilly weather, whether it’s really as unusual as it seems, and whether any sun is on the horizon for the UK.

Ian Sample hears from Linda Geddes about her recent trip to the Netherlands to try cultivated meat sausages, courtesy of the company Meatable. Advocates say that cultivated meat could be the future of sustainable and ethical meat production.

A court in the Philippines has banned the commercial growth of golden rice, a genetically modified rice which was created to help tackle vitamin A deficiency in developing countries. It’s just the latest twist in a long and controversial journey for this rice. Ian Sample hears from the Observer science and environment editor, Robin McKie, and from Glenn Stone, a research professor of environmental science at Sweet Briar College in Virginia who is also an anthropologist who has studied golden rice, about why it has taken so long for this potentially life-saving technology to reach the fields, if it is the silver bullet so many had hoped for, and whether this ban is really the end of the story.

For a long time, western science and Indigenous knowledge have been seen as distinct ways of learning about the world. But as we plunge the planet deeper into environmental crises, it is becoming clear that it is time to pay attention to both. Bridging that gap has been the driving force behind the career of the botanist and author of Braiding Sweetgrass, Robin Wall Kimmerer. She tells Madeleine Finlay what we can learn from the most ancient plants on Earth, why we need to cultivate gratitude for the natural world and what western science can learn from Indigenous knowledge.

It’s been a busy week in the world of artificial intelligence. OpenAI found itself in hot water with Scarlett Johansson after launching its new chatbot, Sky, drawing comparisons to the Hollywood star’s character in the sci-fi film Her. In South Korea, the second global AI summit took place, and a report from the Alan Turing Institute explored how AI could influence elections. The Guardian’s UK technology editor, Alex Hern, tells Madeleine Finlay about what’s been happening. Help support our independent journalism at theguardian.com/sciencepod
