Why do so many people believe in conspiracy theories? It’s a question researchers have wrestled with for decades. And they’ve uncovered many contributing factors, including personality, cognitive biases, social influences and social media use.

There’s been less focus, however, on subtle, everyday influences, such as stress levels or sleep. Now a study has uncovered a link between sleeping badly and believing in conspiracy theories. And while correlation isn’t necessarily causation, the authors argue sleep-focused interventions, such as insomnia therapy, could help counter conspiratorial thinking.

How fast could early human ancestors run? Researchers have worked out that the species Australopithecus afarensis (which the skeleton known as Lucy belongs too), was much slower than modern humans.

And after the US and Ukraine signed a 30-day ceasefire proposal, we look at the factors Russian president Vladimir Putin will now have to weigh up as he considers whether to accept the deal.

By prioritising good sleep we may be able to boost our ability to think critically and resist misinformation.

There has been much debate over the years as to exactly how “Lucy” walked.
