Extra-width spectator seating, bariatric ambulances and oversized coffins are in growing demand

• More than half of adults will be overweight or obese by 2050 – report

With a study predicting that by 2050 more than half of adults and a third of children and young people worldwide will be overweight or obese, a swathe of industries are adapting to accommodate larger bodies. From hospitals to transport, stadiums to crematoriums, here are some of the adjustments being made.

A decade after Chinese investment, La Mosquitia’s processing plant is sitting idle and jobs have been lost as the climate crisis takes its toll

In 2014, Chinese investors visited La Mosquitia, a remote region in eastern Honduras. Amazed by the abundant jellyfish, they eagerly installed a processing plant to export the product to China, where they are served as a delicacy.

Encouraged by the new investments, local communities adopted jellyfish fishing, which quickly became a critical source of income. The trade provided economic benefits in an area with few jobs, increasing local incomes and building community resilience, despite concerns that large-scale jellyfish fishing can disturb marine ecosystems by disrupting food chains.

Angry, rude and addicted to web troll-ery, the vice-president has the Make America Awful Again portfolio. Seems a perfect fit

You may well be aware that Backpfeifengesicht is the German word for a face that is worthy of being slapped. Even so, how has this not been internationalised? Or at the very least Americanised, where its dictionary definition would presumably be adorned by a picture of the face of US vice-president JD Vance – already faultlessly playing the role of worst American at your hotel. You can immediately picture him at breakfast, can’t you? Every single other guest on the terrace with their shoulders up round their ears, just thinking: “Where is he now? How unbearable is he being NOW?” Next, imagine breakfast lasting four years.

I say the Backpfeifengesicht definition would be accompanied by JD Vance’s face … but then again, what is the face of JD Vance? The internet is awash with people suffering an acute case of not being able to remember it any more, having seen so many hideous comic distortions of Vance that those meme versions are not simply the only results on the first page of your own mental Google search, but stretch deep beyond the second and into the third. Somewhere on page four, where you might as well publish the nuclear codes or pictures of Taylor Swift giving cocaine to babies, is an unmodified snap of what JD Vance actually looks like. Or at least what he looks like with eyeliner.
