BBC Inside Science Folgen

The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener: What effect is space travel having on our climate? We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate. How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be? Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way.But is it too good to be true? And will people even eat it? In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is.

Today incredible images were beamed around the world of civilians walking in space – for the very first time. All eyes were on businessman Jared Isaacman and engineer Sarah Gillis as they ventured outside a Space X capsule. But is this an historic space exploration milestone - or just a very exciting holiday for a billionaire? We'll find out more from the BBC’s own expert space-watcher Jonathan Amos. Also this week, we visit Sellafield which processes and stores more radioactive material per square metre than any other site in Europe. But it is getting full. So where is our nuclear waste going to go in future? As the UK searches for a new potential site, we look at the science of what we do with nuclear waste and why. We’ll also delve into the fascinating world of nuclear semiotics. How can we communicate the dangers of nuclear waste to people living 100,000 years from now?
