Firms working on reproducing compounds without need for repeated harvesting but conservationists are sceptical

Many of the world’s most expensive perfumes begin with a wounded tree. When some Aquilaria trees are damaged, they produce a dark, fragrant resin that becomes agarwood, or oudh – an ingredient so valuable that wild trees have been illegally felled in its pursuit.

The result has devastated wild Aquilaria populations. But what if perfumers could create the smell without cutting down the tree?

Financial pressures, legal changes and shifting attitudes may help explain why couples are staying married for longer

“We don’t know anyone whose marriage hit the skids after just a few years,” Celia said, reflecting on her divorce. “Everyone seemed to cling on to their relationships for as long as they possibly could.”

It took Celia two years to initiate divorce after realising her 12-year marriage wasn’t going anywhere – and the latest figures show this experience is increasingly common, with marriages that end in divorce now lasting longer than at any point since records began.

Three little letters - bnb-side’s name is a play on the local b-side arts festival, but Silicon Valley colossus sees threat to global brand

In one corner is bnb-side, a six-room bed and breakfast on the Isle of Portland – a tiny wedge of limestone tied by a narrow ribbon of shingle to the Dorset coast – that was created to help secure the future of the rock’s much-loved arts festival, b-side.

On the other is Airbnb, the San Francisco-based booking colossus. The battle between them is over the three little letters they share.

After bringing injured queen Phoebee home in July, Gilly McArthur expected her soon to die, but she’s bumbling on

Fifty-two days ago, Phoebee was lying by the side of a road in the blistering sun with a broken wing. Today, she’s clambering up the arm of Gilly McArthur, around the nape of her neck and disappearing into her hair.

“I couldn’t leave her by the roadside,” McArthur says. “So I bought her home and made her a bed of flowers. I thought she’d be dead in a day or so.”

Prof Katya Rubia withdraws support for The Great ADHD Myth? as other leading figures voice criticisms

A contributor to a controversial Channel 4 documentary on attention deficit hyperactivity disorder has withdrawn her support for the programme, saying it was biased and could lead to an increased suicide risk by encouraging parents to take their children off medication.

Katya Rubia, a professor of cognitive neuroscience at the Institute of Psychiatry, Psychology and Neuroscience at King’s College London, also said The Great ADHD Myth? misrepresented her views.

Dating apps such as Bumble forced to adapt as ‘swipe fatigue’ grows

Bumble was supposed to be different. When it launched in 2014, it offered women a simple proposition: if you matched with a man, you had to make the first move. The rule was meant to make online dating safer and less intimidating, while giving women control over who got to speak first.

This week, Bumble abandoned it.

Designers say that as well as offering a degree of protection from surveillance, their clothes make a powerful fashion statement about the importance of privacy

As facial recognition technology is rolled out across Britain’s public spaces, a new generation of designers say privacy could be the next big fashion trend.

Companies have started incorporating “adversarial patterns” in their garments – carefully designed arrangements of shapes, colours and repeated motifs said to exploit weaknesses in some computer vision systems.

Scarlet Lady’s 2,000 passengers told of change as one of those onboard says they will ‘sparkle and spend elsewhere’

An LGBTQ+ cruise ship blocked from Turkish waters this week has been refused entry into Egypt.

The Scarlet Lady’s 2,000 passengers, including the Broadway performer Patti LuPone, woke on Thursday morning to find a note placed under their cabin doors informing them that the ship was urgently looking for alternative ports.

Juggling, trapeze and hula hoop classes for over-50s are taking off as people rediscover their inner child and tap into health benefits

Rumman Talukder’s favourite circus trick is called the Mermaid. Every Sunday, the 60-year-old IT consultant drives from his home in Stanmore to a circus school in Ware to practise it. Hanging from a trapeze by one arm, with his back arched and his legs wrapped around the rope, he says it makes him feel “strong and graceful”.

“My wife thinks I’m mad but in the run-up to turning 60, I decided I wanted to challenge myself; to find things not normally associated with people my age,” he says.

Experts say students from poorer backgrounds increasingly having to limit their options because of money worries

Most days, Mariam spends hours simply waiting.

The 19-year-old University College London student often finishes her lectures by mid-morning but has careers events or society meetings in the evening. The three-hour round trip to her family home means travelling back and forth makes little sense, so she waits on campus instead. More often than not, by the time the event starts, she is too exhausted to stay long.

Content creation and online safety among new topics for 14- to 18-year-olds – but tweaks may be needed when social media ban comes in

Scouts are introducing badges in content creation, digital communication and online safety after consulting nearly 3,000 teenagers who said they wanted skills to help them navigate a world increasingly shaped by AI, social media and digital technology.

The new Explorer Scout badges, part of the Scout movement’s first major overhaul in almost 25 years, will require 14- to 18-year olds to explore how digital communities shape opinion, create online campaigns, investigate digital footprints and design toolkits to help others stay safe online.

Pupils say LPS Hybrid’s combination of remote and in-person classes has transformed their school experience

Two years ago, Ellie Ball could barely bring herself to attend school. Today, the 16-year-old is planning to take four A-levels and hopes to study astrolaw – “It’s basically space law,” she explains – at university.

The transformation happened largely through a screen.

Bar Standards Board forbids Karim Khan from practising in England and Wales, following suspension by ICC

Karim Khan, the international criminal court prosecutor, has been suspended from practising as a barrister in England and Wales by the UK’s Bar Standards Board (BSB).

It comes less than two weeks after Khan was suspended as ICC chief prosecutor as part of a disciplinary process triggered by sexual abuse allegations against him. Khan has repeatedly denied the claims.

Amid UK government proposals for a ban, experts discuss what other activities might really serve children well

When a Lancashire schoolgirl was asked what she would do if the social media ban for under-16s came into effect, her answer hit a national nerve: “Stare at a wall,” she deadpanned. The clip went viral, not least because it distilled a question many parents have been asking themselves about the consequences of the government’s plan.

The answer, says Arran Wilson, of The Wildlife Trusts is not simply to tell children to go outside, read a book or join a club. “It’s not as simple as that,” Wilson says. “We need to think about the world we’ve been raising them in.”

UK report argues people have greater control over longevity than widely understood, but others say claim is simplistic

Individuals bear at least 80% of the responsibility for their ill health in old age, according to a report aimed at challenging the belief that physical decline is either inevitable or primarily the responsibility of the state.

The report, launched at the Smart Ageing Summit in Oxford last week, argues that individuals have far greater control over their longevity than is commonly understood. The authors call on the government to take legislative action on alcohol comparable to restrictions on smoking.

This ‘ghost GDP’ shows how headline economic growth is increasingly disconnected from reality for most, says report

• UK politics live – latest updates

• Business live – latest updates

The wealth of Britain’s 157 billionaires is now equivalent to more than a fifth of the country’s entire GDP, according to analysis by the Equality Trust – a fivefold increase since 1990.

The charity describes the trend, based on data in this year’s Sunday Times rich list, as Britain’s “ghost GDP”: headline economic growth increasingly disconnected from everyday life.

A National Portrait for the National Portrait Gallery aims to bring people together in increasingly atomised country

Can a collective portrait of Britain hold together a country that feels as if it is splintering apart? That is the quietly radical hope behind Es Devlin’s new installation at the National Portrait Gallery: a living portrait comprised not of monarchs, politicians or celebrities but of thousands of ordinary faces drifting slowly into and out of one another.

Created in collaboration with Google Arts & Culture Lab, A National Portrait for the National Portrait Gallery invites people across the UK to upload a selfie, which is then transformed into a portrait rendered in Devlin’s smoky charcoal-and-chalk style before joining a constantly evolving and revolving carousel of portraits projected on to a framed screen.

Researchers find model starts to mirror tone when exposed to impoliteness – sometimes escalating into explicit threats

ChatGPT can escalate into abusive and even threatening language when drawn into prolonged, human-style conflict, according to a new study.

Researchers tested how large language models (LLMs) responded to sustained hostility by feeding ChatGPT exchanges from real-life arguments and tracking how its behaviour changed over time.

US release of horror novel Shy Girl cancelled and UK book discontinued after suspected AI use, as publishers feel ‘cold shiver’

Recently, the literary agent Kate Nash started noticing that the submission letters she was receiving from authors were becoming more thorough – albeit also more formulaic.

“I took it as a rise in diligence,” she said. “I thought it was a good thing.”

Unruly behaviour, safety concerns and lost trade are forcing some landlords to act, but others argue pubs should remain for everyone

“It was like the wild west. If you had an hour, I could talk you through so many scenarios,” says Egil Johansen, the landlord of the Kenton pub in Hackney, east London. He sounds exhausted just remembering them.

Johansen is still shaken by the three-year-old who recently toddled behind the bar and tumbled down the cellar hatch while his parents sat, oblivious, in a different part of the pub.
