After a summer that has seen England and Wales experience the driest July since records began, rain is finally on the horizon. But with reservoirs at ‘exceptionally low’ levels, will there be enough rain to replenish stocks? Madeleine Finlay hears from Dr Anna Murgatroyd, a lecturer in hydrology at Newcastle University, about how much rain we need to see us through next summer, why we’re now at increased risk of floods, and what we can all be doing to take better care of our water supplies.

One of the UK’s best fossil collections has been sold overseas in what experts have called a loss to the nation. The collection, which is now on display at the Natural History Museum in Abu Dhabi, was gathered on Dorset’s Jurassic Coast. As dinosaur fossils sell to private collectors for increasingly large sums, scientists are worried that domestic museums are being priced out of the market, and in turn scientists are missing out on the opportunity to make new observations. To find out how fossils became big business and what it could mean for research, Madeleine Finlay hears from science correspondent Nicola Davis.

Books have never been trendier, but studies show that as more and more things compete for our frazzled attention spans, we’re reading less and less. This is a problem because reading has a wealth of cognitive benefits that we’re in danger of missing out on. To find out why declining literacy could affect everything from memory to IQ, Madeleine Finlay speaks to the Guardian’s science editor, Ian Sample. She also hears from Prof Falk Huettig, an experimental psychologist at the Max Planck Institute for Psycholinguistics and author of The Perks of Being a Bookworm.

Madeleine Finlay travels to the Rothbury estate in Northumberland, in north-east England. It’s a piece of land that has been in the same family for 700 years, but now it has been put up for sale and the UK’s Wildlife Trusts are trying to raise £30m to secure it intact. To find out what makes the area so special, Madeleine speaks to Katy Barke, the head of nature recovery for Northumberland Wildlife Trust. She also hears from Sam Turner, a professor of archaeology at Newcastle University, who is trying to work out how the land has been used across the centuries. This work will inform the strategy for nature recovery on the site. And Rosie Pearce, a farm liaison officer, explains how the project could bring more wildlife-friendly farming practices to the estate.
