Researchers warn generative tools are helping militant groups from neo-Nazis to the Islamic State spread ideology

While the artificial intelligence boom is upending sections of the music industry, voice generating bots are also becoming a boon to another unlikely corner of the internet: extremist movements that are using them to recreate the voices and speeches of major figures in their milieu, and experts say it is helping them grow.

“The adoption of AI-enabled translation by terrorists and extremists marks a significant evolution in digital propaganda strategies,” said Lucas Webber, a senior threat intelligence analyst at Tech Against Terrorism and a research fellow at the Soufan Center. Webber specializes in monitoring the online tools of terrorist groups and extremists around the world.

• Vonn places third again in super-G at Val-d’Isère

• 41-year-old logs 142nd World Cup podium finish

• Milan-Cortina Olympics firmly in sight for US star

Sofia Goggia finally got the win her fast skiing this season deserved in a World Cup super-G on Sunday and Lindsey Vonn was third for the second straight day.

The two former Olympic downhill champions were split on a high-class podium by runner-up Alice Robinson, who is already a two-time winner this season on the World Cup circuit.

Attackers wound 10 others in Bekkersdal after opening fire at people in a bar and ‘randomly’ shooting in the street, police say

Nine people have been killed after gunmen opened fire at a bar near Johannesburg in the second mass shooting in South Africa this month.

Ten more were wounded in the early morning attack at the tavern in the impoverished Bekkersdal township in a gold mining area about 25 miles (40km) south-west of Johannesburg.

Group of 120 experts including Joseph Stiglitz urge fresh debt restructuring plan given scale of destruction

A group of the world’s top economists – including the Nobel prize winner Joseph Stiglitz – have called for Sri Lanka’s debt payments to be suspended as it tackles the devastation caused by Cyclone Ditwah.

More than 600 people were killed and hundreds of thousands of homes destroyed across the island, in what Sri Lanka’s president, Anura Kumara Dissanayake, called the “largest and most challenging natural disaster in our history”.

Maria Farmer, whose sister Annie was abused by Epstein and Ghislaine Maxwell, says Epstein ‘stole’ nude images

While Donald Trump’s justice department did not deliver on a legal requirement to disclose all Jeffrey Epstein-related files by Friday, one document in an otherwise underwhelming disclosure lifted the veil on authorities’ inaction – and its dire consequences for dozens of teen girls.

That document is an FBI report from Maria Farmer, a painter who worked for Epstein around 1996.

The commercialisation of the cosmos is already underway, and our current laws aren’t fit for purpose

If there is one thing we can rely on in this world, it is human hubris, and space and astronomy are no exception.

The ancients believed that everything revolved around Earth. In the 16th century, Copernicus and his peers overturned that view with the heliocentric model. Since then, telescopes and spacecraft have revealed just how insignificant we are. There are hundreds of billions of stars in our galaxy, the Milky Way, each star a sun like ours, many with planets orbiting them. In 1995, the Hubble space telescope captured its first deep-field image: this showed us that there are hundreds of billions of galaxies in our known universe, huge wheeling collections of stars dispersed through space.

From Emily Henry to Rebecca Yarros and Alison Espach’s The Wedding People – romance has dominated the book charts this year. So why is it still dismissed by critics?

People buy lipstick when the world is falling apart. This genuine economic theory, known as the “lipstick index”, was first noted by Leonard Lauder (son of the more famous Estée). When the world seems very bleak – in the weeks and months after the twin towers fell, for instance, or after the 2008 financial crash – and spending generally goes down, lipstick sales trend strongly upwards.

The psychological truth at the heart of this equation is real: when people have less than they need, they spend more on small, beautiful things. It’s easy, maybe, to dismiss this in the way most feminine-coded things are dismissed: frivolous, wasteful, foolish. But that would be a mistake. A single treasure, bright and gorgeous, is like a talisman; a candle in the night. It is possible, with your small candle, to make your way in the darkness. One delight, against all this. The world crumbles, and lipstick sales go up.

Fear that confrontation is on the cards as policing of ships becomes more aggressive and Russia challenges Europe

The “shadow fleet” used by Russia, Iran and Venezuela to avoid western sanctions and ship cargo to customers including China and India is “exploding” in its scale and scope, and there are concerns that efforts to counter it are drawing closer to dangerous military confrontations.

Complicating the issue is that Russia has begun putting its own flag on some former shadow fleet tankers, in an open challenge to Europe.

So this is Christmas. And what have we done? The Ashes is over. With two Tests still to come

When the moment finally came the visuals were perfect: clean lines, neat angles, figures picked out in crisp afternoon sun against the almost satirical splendour of Adelaide Oval.

Scott Boland took the final wicket to seal Australia’s unassailable 3-0 Ashes series lead, the 74th time this moment has been played out down the centuries, and immediately the white shapes converged to form a bobbing huddle. England’s batters stood in an attitude of formal deflation. The umpires began their priestly last-things walk, framed against that huge, empty, lime-green field.

As Congress cuts healthcare access to pay for tax cuts and poor Americans die earlier, billionaires invest in anti-ageing

There’s a weird disconnect to the public debate about health in the United States. In January, millions of Americans may drop their health insurance as premiums skyrocket following the Trump administration’s decision to end federal subsidies that helped some 20 million people afford insurance on the Obamacare marketplaces.

Earlier this year, Republicans in Congress agreed to cut more than $850bn from the 10-year budgets of Medicaid, the health insurance program for low-income people, and the Chip health insurance program for children, in order to pay for some tax cuts. Given the US’s budgetary rules, that cut means an additional $500bn in funding for Medicare is at risk.

As rising seas salinise the soils of the Venice lagoon, scientists and chefs are turning to long-forgotten wild herbs

On the scrubby banks of the rural swathes of the Venice lagoon, an evening chorus of cicadas underscores the distant whine of farmers’ three-wheeled minivans. Dotted along the brackish fringes of the cultivated plots are scatterings of silvery-green bushes – sea fennel.

This plant is a member of a group of remarkable organisms known as halophytes – plant species that thrive in saltwater. Long overlooked and found growing in the in-between spaces – saltmarshes, coastlines, the fringes of lagoons – halophytes straddle boundaries in both ecosystems and cuisines. But with shifting agricultural futures, this may be about to change.

The Norwegian star was considering giving up acting to be a carpenter when Joachim Trier wrote The Worst Person in the World for her. Now the pair have teamed up again – but she refuses to get carried away by all the praise

One day in July 2021, Renate Reinsve got up, read the Guardian and promptly vomited. It was – mostly – a happy kind of hurl. The Norwegian actor was at Cannes, where The Worst Person in the World had premiered the previous evening. Joachim Trier’s film, which follows Julie, a young woman on a capricious yet uncompromising quest for meaning and happiness, was the first Reinsve had ever starred in. During the screening, she decided “this movie is great, but I am shit!” Hours later she was confronting the possibility that she might be one of the greatest actors of her generation. This newspaper’s verdict – “A star is born” – was, she said, “too much to process, so I just started puking. My whole image of myself and what I could do just changed instantly.”

Reinsve went on to win the best actress prize at the festival. Her performance would later be shortlisted for a Bafta and a slew of other awards (the film itself received two Oscar nominations). The accolades certainly helped on the self-esteem front, but the 38-year-old knew she mustn’t let the acclaim go to her head. “I was very overwhelmed and then I sat with it and was like: OK, I need to keep a distance to this somehow,” she recalls, sitting on the sofa in a cavernous hotel suite in Soho, London. “You can’t take criticism too personally and you can’t take praise too personally.” Such affirmation, I imagine, must become addictive. “Yes. And everything in life shall pass. So the aim was to keep everything a little bit even and keep the image I have of myself intact.”

Jewish leaders call for federal royal commission into Bondi beach attack that killed 15 people as huge crowd marks one week anniversary

Jewish leaders have called for a federal royal commission into the Bondi terror attack, as some members of the crowd booed Anthony Albanese on arrival at the commemoration marking one week since 15 people were killed on the first day of Hanukah.

The president of the NSW Board of Jewish Deputies, David Ossip, said it “cannot be disputed” that a federal royal commission was needed, to loud cheers and applause from the crowd of up to 15,000 people gathered at Bondi, where a minute’s silence was held at 6.47pm, the time the attack began.

There’s some interesting debate raging below the line about the tempestuous meeting between Tottenham and Liverpool last night, where Xavi Simons and Cristian Romero were sent off but Micky van de Ven, whose challenge ended Alexander Isak’s involvement was not.

Thomas Frank was certainly of the view that Simons sending off was unjust. “I don’t like those types of red card because I think the game is gone if that’s a red card,” he told the BBC soon after the game finished. “I don’t think it’s a reckless tackle. I don’t think it’s exceptional force. We have the referee’s call and that was a yellow, so that’s why I don’t think that’s a red.”

The chancellor is pursuing a risky quest for European leadership, and last week’s setback over Russian reparations is unlikely to knock him off course

Friedrich Merz’s three-month bid to catapult Germany into the role of undisputed leader of Europe has come unstuck.

His call for Europe to hand Ukraine access to €201bn (£176bn) in frozen Russian central bank assets via a reparations loan was rejected at a decisive European Council meeting in Brussels.

• Tourists’ skipper ‘absolutely’ has energy to stay in role

• Head coach after defeat: ‘Sitting here 3-0, it didn’t work’

As Ben Stokes stressed his commitment to leading England after losing the Ashes inside 11 days, Brendon McCullum gave his first admission of regret. Poor preparation has been widely blamed for this failed tour of Australia and, in that regard, the head coach was prepared to hold his hand up.

Speaking after the 82-run defeat at Adelaide Oval that sees Australia 3-0 up with two Tests in Melbourne and Sydney to come, Stokes offered a simple “absolutely” when asked if he had the energy to continue as captain but played down England’s threadbare warmup period.

Former Manchester United player discusses culinary and cultural surprises, feeling more mature and how he learned Korean

Jesse Lingard says his Korean is decent, good enough to make himself understood when out for dinner and the shocks do not stop there. The former Manchester United and England midfielder was always going to throw himself into his K-League adventure with FC Seoul and now that it is over after two years, a new chapter beckoning when the January transfer window opens, the 33-year-old certainly has the tales to tell.

It was the little things as much as anything else, the cultural quirks. And the bigger ones, of course – such as the time he watched an octopus squirm in front of him before eating it. “The food is different, obviously, and I tried live octopus,” Lingard says. “It was moving. I was scared at first but it was all right.”

The feeling among fans is anticlimatic as ‘businessmen have appropriated the ball that used to belong to the people’

Jonathan Zamora was seven years old the last time Mexico hosted the World Cup in 1986. “I witnessed perhaps one of the most sublime moments in the history of football,” he says, retelling a story that has become a pillar of his life.

Zamora, a Mexican football fan, does not remember how his father, Antonio, got tickets to the 1986 World Cup quarter-final between Argentina and England at the Azteca Stadium in Mexico City. But he does clearly remember the goals: first when Diego Maradona used his “hand of God” to push the ball past England goalkeeper Peter Shilton. And then the “goal of the century”, where the Argentinian went on a slalom run, dribbling past half the England team before scoring.

PostNord’s decision to end service on 30 December comes after fear over ‘increasing digitalisation’ of Danish society

The Danish postal service will deliver its last letter on 30 December, ending a more than 400-year-old tradition.

Announcing the decision earlier this year to stop delivering letters, PostNord, formed in 2009 in a merger of the Swedish and Danish postal services, said it would cut 1,500 jobs in Denmark and remove 1,500 red postboxes amid the “increasing digitalisation” of Danish society.

You consider yourself wise to other scams, and have ignored texts claiming to be from him and asking for cash. But you can hear his voice and he is clearly in trouble.
