Why it matters that Trump fired data chief

On Friday 1st August the US Bureau of Labor Statistics put out their job report data for August. It included revisions to their estimates for the jobs created in May and June which stated there were 258,000 fewer jobs than they had previously estimated. This news was not received well by the White House. President Trump fired the head of the bureau, Erika McEntarfer, calling the numbers ‘phony, rigged, a scam’ and spreading conspiracy theories that McEntarfer had fudged the data. We speak to economist Michael Strain from the American Enterprise Institute, to understand why the revisions happened and the potential consequences of throwing doubt on one of the US’s most important statistical agencies. If you’ve seen a number in the news you think we should take a look at, email the team: moreorless@bbc.co.uk Presenter: Lizzy McNeill Producer: Lizzy McNeill Series Producer: Tom Colls Production Co-ordinator: Rosie Strawbridge Sound mix: Neil Churchill Editor: Sam Bonham

Are abortion numbers rising in the US?

In June 2022 the United States Supreme Court passed what became known as ‘the Dobbs decision’. In doing so they overturned the long standing constitutional right for women to access abortion in the US. Since then a number of states have banned abortion completely with many others having highly prohibitive rules. You’d expect the numbers of abortions to go down. They haven’t. How is it possible that more people are accessing abortions in a post Dobbs society and why is it not true that states which have total bans have zero abortions per year? Presenter: Lizzy McNeill Producer: Lizzy McNeill Series Producer: Tom Colls Production Co-ordinator: Rosie Strawbridge Studio Manager: Neil Churchill Editor: Richard Vadon, Bridget Harney.

Does a single AI query use a bottle of water?

We’re living through boom-times for Artificial Intelligence, with more and more of us using AI assistants like ChatGPT, DeepSeek, Grok and Copilot to do basic research and writing tasks. But what is the environmental impact of these technologies? Many listeners have got in touch with More or Less to ask us to investigate various claims about the energy and water use of AI. One claim in particular has caught your attention - the idea that the equivalent of a small bottle of drinking water is consumed by computer processors every time you ask an AI a question, or get it to write a simple email. So, where does that claim come from, and is it true? Reporter: Paul Connolly Producer: Tom Colls Production co-ordinator: Brenda Brown Sound mix: Donald McDonald Editor: Richard Vadon

Liker at det er både Podcaster (godt utvalg) og lydbøker i samme app, pluss at man kan holde Podcaster og lydbøker atskilt i biblioteket.
Bra app. Oversiktlig og ryddig. MYE bra innhold⭐️⭐️⭐️
