Yes, many Americans are struggling, but it’s good to know the first family can still afford Earth’s most expensive provisions. Morale is everything, isn’t it?

In the absence of any clearly and consistently stated aims from the US administration, maybe each day of the Iran war just needs a moodboard description. In which case, Sunday was a tale of two nepo babies. In Iran, the high-level executive search for the new ayatollah concluded that the old ayatollah’s son was the best man for the position. It’s not for me to assess his job prospects, but you’d hope his supermarket order doesn’t contain any “ripen at home” pears.

Meanwhile, across the world, in LA, Donald Trump’s eldest granddaughter posted a YouTube video titled “I Brought My Secret Service to Erewhon”. By way of background, Erewhon is Earth’s most pretentiously extravagant hipster food shop, and, as Kai was at pains to brag, “the most expensive grocery store pretty much out there. Everything’s crazy expensive! So we’re going to get my favourite stuff.”

The raunchy 80s adaptation of smash hit novel A Woman of Substance drew the highest ratings Channel 4 has ever seen. As the broadcaster goes there again, the cast and creators talk feminism, revenge – and sex caves

Somewhere on the West Yorkshire moors is what the team behind A Woman of Substance nicknamed “the sex cave”. It is here that the heroine, Emma Harte, loses her virginity in the lavish new adaptation of Barbara Taylor Bradford’s bonkbuster. “It’s hidden away and beautiful,” says the showrunner, Katherine Jakeways. “The lighting in there almost looks like AI, but it’s real. Weirdly, it’s about a mile from my mother-in-law’s house. I haven’t told her yet that it’s a sex cave!”

This is just one of many unusual sites for sex scenes featured in the show. “Oh my God, I know,” laughs Jessica Reynolds, who plays the young Emma. “Not just the cave, but there’s a little love shack, too. The cave is the most stunning location, with sunlight coming through these arching rocks. I wonder if they used it in Wuthering Heights, too? If they didn’t, they should have.”

Remember the iPod? How about the Pippin? In the half-century since it launched its first PC, Apple has given us some amazing innovations. We round up its biggest triumphs and flops

Fifty years after Steve Jobs, Steve Wozniak and Ronald Wayne founded the company in Jobs’ parents’ garage in Los Altos, California, Apple has become a behemoth, and billions of us use its products every day. From the first successful home computers with colour screens, to the iPod, to the smartphone that set the template for the modern mobile era, the company has repeatedly reset consumer expectations.

As a result, the firm occupies a central position in the tech world, initiating trends and popularising products. Here are five of its most influential products from the past half-century – alongside some unusually big misses.

Oil markets have had some of the steepest price rises ever recorded as conflict in the Middle East escalated over the last week. Although the world is slowly becoming greener, fossil fuels are still the lifeblood of every economy so when oil and gas prices rise, the effect ripples through almost every aspect of our financial lives. Jillian Ambrose, energy correspondent for the Guardian, explains how the conflict may affect global costs.

• Oil prices ‘could breach $100 a barrel within days’ amid supply disruption from Iran war

Psychologist Leanne ten Brinke has spent decades studying toxic personality traits. What are the red flags to look out for among workmates, politicians and potential partners?

Coming face to face with a probable psychopath was enough to make Dr Leanne ten Brinke rethink her career choices. Early in her 20s, while studying forensic psychology in Halifax, in the Canadian province of Nova Scotia, Ten Brinke was volunteering at a parole office, which would hold weekly group meetings for released sex offenders. “Most of the men showed contrition,” says Ten Brinke. “They really seemed to recognise the damage that they had done.” Except for one. The treatment programme seemed “like a game to him”, she says. One week, in a discussion about the impact their crimes had on victims, this rapist stared at Ten Brinke and, smiling slightly, started to say how much his victim looked like her, “and how I was ‘his type’. Clearly he was trying to scare me, and he did.”

It put her off a career working with convicted criminals, but she remained fascinated with “dark personalities” – psychopathy, mainly, but also narcissism, machiavellianism (manipulating and exploiting others) and sadism. From politics to business to the media, it wasn’t as if there was a shortage of people to study. There were selfish, callous, impulsive and manipulative people everywhere, often presenting as gregarious and charming. “It started to occur to me that these traits aren’t just confined to an underworld. These traits appear in all aspects of our lives,” she says.

When Trump granted white South Africans refugee status, he was echoing a falsehood about Black people taking revenge for years of brutality. But no one flourishes in a repressive police state

There’s a little town in the scrub in South Africa – a full day’s drive from the country’s big cities – that has become perhaps the most scrutinised place on earth, given its size. It is 9 sq km (3.5 sq miles) of suburban-style houses harbouring about 3,000 people, with a main drag, a municipal swimming pool, one gas station and some pecan farms. Nothing of consequence ever really happens there, a fact the townspeople take as a point of pride. And yet over the past three decades, dozens of English-language news outlets have made a pilgrimage to it, often more than once. The New York Times alone has run four dedicated profiles. The essays have kept pace year after year, quoting the same people over and over, even as nothing of note occurred. There’s been no war, no disaster.

That changelessness is the point. No people of colour are allowed to live in the town, called Orania. The name is a nod to the river that runs nearby – and to the Orange Free State, the apartheid-era designation for the province in which it lies. Orania’s founders established it in 1991, the year after South Africa’s best-known Black liberation leader (and future president), Nelson Mandela, was freed following 27 years in prison.

The US defence secretary says the military is increasing attacks on the regime

• Pete Hegseth warns of day of ‘most intense’ US strikes on Iran yet

• How have you been affected by the latest Middle East events?

Investor hopes for a swift resolution to the Middle East conflict propelled Australian shares higher today, with the benchmark S&P/ASX 200 finishing the day up 1.1% and recovering about $35bn in value after yesterday’s $90bn plunge.

Oil prices surged to a four-year high early in the week before coming back down below $US90 a barrel after Donald Trump suggested the Iran conflict would end soon, sending global stock markets higher.

The government said a week ago the warship would be deployed but it is still at dock. What is happening?

• Middle East crisis – live updates

• UK politics live – latest updates

The pace at which HMS Dragon has been readied for deployment to defend a British military base in Cyprus from attacks by Iran has prompted claims that Britain’s proud naval history has been shamed.

It has been a week since the government said the Portsmouth-based Type 45 destroyer would be deployed, but it is still at dock and the ship is likely to take another five days or more to reach its destination.

Trump has blamed Iran for the mass killing at Shajareh Tayyebeh primary school but geolocation, videos and satellite imagery indicate otherwise

The bombing of a primary school in Minab on 28 February killed scores of people, most of them seven- to 12-year-old girls. The strike is the worst mass killing of the US and Israel’s war on Iran so far – and has been described by Unesco as a “grave violation” of international law.

On Saturday, the US president, Donald Trump, declared that Iran was responsible for the school bombing. “In my opinion, based on what I’ve seen, that was done by Iran … they’re very inaccurate, as you know, with their munitions. They have no accuracy whatsoever. It was done by Iran.”

Only two vessels not linked to Iran or Russia have braved ‘chicken run’ since US president’s promise on Friday

• Middle East crisis – live updates

Only two vessels not linked to Iran or Russia have made the “chicken run” through the strait of Hormuz since Donald Trump said he would “ensure the free flow of energy to the world”, according to maritime records.

One of those that braved the journey since the US president’s announcement of emergency measures on Friday went “dark” by switching off its transponder and a second signalled it was Chinese owned and crewed.
