If you’re in a city or large town in England, chances are wood burning is strongly restricted in your area. Yet you could still walk into your local garden centre and buy firewood and a wood-burning stove. It’s very confusing and must be one of the easier rules to break, even by accident.

The confusion is partly because the tools used to control wood burning date back to the great smogs of the 1950s, says James Heydon of the University of Nottingham. Those rules were aimed at thick, industrial smog, not the tiny invisible particles emitted by wood fires – and this loophole persists today. With the use of wood-burning stoves growing fast, Heydon looks at the options.

“Scrambled eggs. Oh my baby how I love your legs…” Say it out loud. If the rhythm sounds familiar that’s because those were the original lyrics to Yesterday by the Beatles. Paul McCartney said he used them as a placeholder after the melody for the song suddenly came to him came to him one drowsy morning. Psychologists call this the “hypnagogic state”, and Steve Taylor of Leeds Beckett University says it’s responsible for many great discoveries and inventions.

Meanwhile, the dominance of the US dollar may be unravelling under Trump, as America can no longer be relied on to act predictably or responsibly. Fabian Pape of the University of Edinburgh and his co-authors explain why this is happening and why it matters.

Many artists and scientists have had breakthrough while in this drowsy state between sleep and waking.

Is the dominance of the US dollar unravelling under Trump?

The erosion of trust in the US as the steward of the liberal international order should be taken seriously.
