From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

Researchers at the University of Chicago say sleeping enables the brain to recover lost memories and appears to be essential for remembering names, telephone numbers and where you put the keys.
They found that people improved at memory experiments after a good night's sleep. In the journal Nature, the scientists, Kimberly Fenn, Howard Nusbaum and Daniel Margoliash, say: "Sleep consolidates memories, protecting them against subsequent interference or decay. Sleep also appears to 'recover' or restore memories."
Their study involved testing students who were asked to recognise the words spoken by a voice synthesiser which involved learning and remembering unusual speech patterns. Most remarkable was the loss of learning the students experienced during the day and then recovered.
