For three weeks, I wore stickers on my skin supposed to address all sorts of conditions. Are they a panacea, problem or performance?

This morning, I woke up feeling a little groggy. My go-to remedy is usually a coffee and cold-water face plunge, followed by a compulsive phone scroll. But today called for something more, so I unpeeled a small, yellow “energy” patch the size of a walnut, popped it on to my upper arm and hoped for the best.

The patch (£12 for 30) contains – so the packaging says – vitamins B5, B3 and a “microdose” of caffeine. It is made by Kind Patches, which is one brand in an increasingly crowded market of wellness stickers that claim to treat everything from lack of sleep to period pains to pimples. They are coin-sized, and often come in TikTok-friendly shades of sunflower yellow and peachy orange: you may have seen a teenager sporting a star-shaped one on their face to treat spots, or influencers patting blue magnesium ones on their wrists before bed.

The idea that the liberal rules-based order can survive his presidency now seems complacent. This is a historic moment – and a time to act

A European-wide chorus of resistance, led this morning by Keir Starmer, has greeted Donald Trump’s plan to take over Greenland, by force if necessary, and to start a tariff war if any country stands in his way. Have no doubt, this is a moment: if pursued as a non-negotiable demand, Trump’s plan ends any lingering hope that the liberal rules-based order can stumble on through his remaining time in office. The real question now is whether the 2020s will be defined by the complete collapse of the order’s already crumbling pillars and the atrocities accompanying it, or whether an international coalition of the willing can come together to build a new global framework in its place.

For, in quick succession, the US has abandoned its longstanding championing of the rule of law, human rights, democracy and the territorial integrity of nation states. Gone is its erstwhile support for humanitarian aid and environmental stewardship. Gone, too, is the founding principle of the postwar settlement: that countries choose diplomacy and multilateral cooperation over aggression and unilateral action. We cannot doubt any longer that the president meant it when he said he doesn’t “need international law”, and that the only constraint on his exercise of power would be “my own morality, my own mind”.

Years of civil war have turned whole areas of the city into rows of empty husks. But after the fall of Assad, Syrians have returned to their old homes determined to rebuild

The kebab stall stood in the shadow of a building whose three upper floors had been sheared in half, leaving behind concrete slabs that seemed to hang in mid-air. Under a tarpaulin, its edges weighted with cinder blocks, stood a thin man with a thick white beard. Smiling, he stoked the fire in a narrow grill. Walking back and forth to a table set atop a wheelbarrow, he tenderly inspected a dish laid out with tomatoes, greens and a few skewers of meat. A torn mat covered the floor, while a plastic ice box and a few more cinder blocks provided seating for the customers who were yet to appear.

The streets were largely deserted here in Amiriya, a dilapidated suburb of Aleppo that once formed the frontline between the rebel-held enclave and government-controlled areas. But there were a few signs of life: children hopping on and off a rusty motorcycle, a woman selling cigarettes and water from a shack, a young man digging through the rubble with his hands, pulling out pieces of limestone and stacking them in a neat pile to use later in rebuilding his own house. “They are much better than the new ones,” he told me.

Tom Burgis on Donald Trump’s friend Ronald Lauder, a billionaire with business interests in Greenland

“The thing to remember, always, with Trump is that everything is about the psychodrama,” the Guardian investigations correspondent Tom Burgis tells Helen Pidd. “Everything is who’s in his ear, what bit of his vanity or insecurity has been activated.”

In this episode, Tom explains the backstory to the US president’s interest in Greenland. According to John Bolton, the former national security adviser, the story began in 2018 with a conversation between Trump and the billionaire Ronald Lauder.

Concentrated among 1,000 people in the remote Daliwe valley, siPhuthi has gained a dictionary, a Bible translation and official recognition thanks to intrepid linguists and activists

Tsotleho Mohale was addressing a group of people gathered on a mountainside still damp from an intense rainstorm that morning. The peaks on the other side of the steep valley were draped in cloud. Mohale was speaking in siPhuthi, a language spoken by just a few thousand people in parts of southern Lesotho and the north of South Africa’s Eastern Cape province, about the plants he used and the ailments he cured as a traditional healer.

The questions came from Sheena Shah, a British linguist, and were translated into siPhuthi by Mohale’s grandson Atlehang. Shah’s German colleague Matthias Brenzinger was filming the exchange. The two academics have been travelling regularly to Daliwe, a remote valley in Lesotho about 15 miles from the nearest paved road, since 2016, working with local interpreters and activists to document siPhuthi.

The Glory was a haven for outlandish self-expression and the early stomping ground for many of the UK’s most infamous drag queens. It made me ready for life

In a packed pub, revellers chat, sip lager and look at their phones. Suddenly a side door crashes open, and in walks drag sensation John Sizzle, dressed as a hair-raisingly accurate Diana, Princess of Wales. She saunters demurely to a halo, fashioned from tinsel and coat hangers and stuck to the wall, stands under it, and starts lip-syncing to Beyoncé’s Halo. The crowd erupts.

US president says the UK’s decision to hand over sovereignity of the islands is among a ‘long line’ of reasons why Greenland ‘has to be acquired’

• Donald Trump links Greenland threats to Nobel snub as EU trade war looms

Reform UK, led by Nigel Farage, has vowed to overturn the Chagos Islands agreement, saying the costly agreement was fuelled by a misplaced feeling of “postcolonial guilt” in a government “run by human rights lawyers”.

In a post to X this morning, Farage, who has a close relationship with Donald Trump, said: “Thank goodness Trump has vetoed the surrender of the Chagos islands.”

Exclusive: Green party leader advocates leaving Nato and says Britain should wean itself off its reliance on the US

The UK should consider expelling the US from British military bases, the leader of the Green party has said, as he advocated leaving Nato and spending less on American weapons as part of a wider dismantling of the two countries’ defence alliance.

Zack Polanski told the Guardian he believed Britain should wean itself off its reliance on American military cooperation, though would not say whether he supported spending more money to replace that capability.

Plans to speed up airspace changes for Heathrow expansion could mean industry influences decisions on noise and routes

Aviation campaigners have warned that communities risk being locked out of decisions about new flight paths as the government accelerates reforms that will allow a third runway at Heathrow to go ahead.

Airspace around the UK will be reconfigured as part of a long-running modernisation process to allow planes to fly more efficiently and minimise delays, and the London airport has said progress in this area is essential for its expansion.
