Summer heatwaves and missed bin collections have created panic in the press that rat numbers in the UK are increasing. We ask Steve Belmain, Professor of Ecology at the Natural Resources Institute at the University of Greenwich for the science.

This summer Wales became the first country in the UK to ban plastic in wet wipes, with the other nations pledging they will do the same. Over the past few weeks there’s been work to remove a giant mound of them, known as ‘Wet Wipe Island’ on the Thames in west London. Marnie Chesterton has been to find out how they got there and what damage they could be doing to the river’s ecosystem.

Professor Sadiah Quereshi, Chair in Modern British History at the University of Manchester explains why we should see the extinction of species as a modern, and often political phenomenon. Her book Vanished: An Unnatural History of Extinction is the second book we’re featuring from the shortlist for the 2025 Royal Society Trivedi Science Book Prize.

And Lizzie Gibney, senior physics reporter at Nature brings us a round up of the news causing a stir in science circles this week.
