Everyone hates datacentres. Do we really need them?

AI companies have promised us world-shifting technology. But there’s a cost: loud, unsightly datacentres that drain environmental resources. As the government pushes their rapid growth, can local communities do anything to push back? Madeleine Finlay speaks to the Guardian’s global technology reporter Aisha Down about the backlash to datacentres across the UK and around the world.

It’s finally raining. Will it be enough to end the drought?

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.

The ultra rich are collecting fossils, and that’s bad for science

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.
