As young people take on a messy dating landscape, they’ve created their own lexicon to match. Here’s like what phrases ‘bird theory’ and ‘monkey branching’ mean

This year marked a decade since the term “ghosting” hit the mainstream. At the time, the idea that someone could abruptly cease communication with a lover without explanation seemed like the peak of indignity. How naive we were. In the 10 years since, finding a partner has only become more confounding – an oftentimes fruitless exercise in humiliation that is increasingly pigeonholed by social media jargon.

Gen Z, a cohort who came of age during a loneliness epidemic, a masculinity crisis, and a coordinated attack on the rights of women and the LGBTQ+ community, faces a far messier landscape than their millennial predecessors could ever imagine. And so their dating glossary has grown longer and more deranged, with phrases like “Shrekking” and “monkey branching” testing the limits of your sanity.

Red flags – Behavioral quirks indicating a potential partner is bad news. Examples include calling their exes crazy, subpar tipping habits, a love of Woody Allen films, a burgeoning DJ career …

Green flags – These quirks validate your decision to pursue a mate. Examples include checking in to make sure you got home safe after a date, low screen time, owning a bed frame …

Beige flags – These usually describe niche, mostly benign quirks. Examples include being an enthusiastic birdwatcher, still carrying around a pen in their purse, paying rent in cash …

From freezing rents to free buses and municipal grocery stores – a recap of the policies that won Mamdani the office

Zohran Mamdani was sworn into office as New York’s 111th mayor at the stroke of midnight, the first Muslim mayor as well as the first to take office as a Democrat bearing the credentials of a democratic socialist.

The 34-year-old was sworn in by Letitia James, the state attorney general, in a disused subway station beneath city hall that acts as turnaround for the local 5 train, to be followed by a first-of-its-kind public block party along Broadway’s “Canyon of Heroes”.

The new mayor embraces social justice, and rejects hate and nationalism. That’s why we’re so excited to see what he’ll do in office

On a cold Saturday morning, a little over a week before the New York City mayoral election in November, I was at a park in Queens to speak at a fundraiser for Asiyah Women’s Centre, the oldest and largest shelter providing support for American Muslim female victims of domestic violence. Vendors selling everything from chai to embroidered Palestinian handicrafts turned out to support the fundraiser; a DJ blasted music and artists painted children’s faces with the colours of Halloween.

I chose the vendor with the most protein on offer because I lift and squat more than my bodyweight and must meet a daily goal. “Our kebab is one of Zohran’s favourites,” the man at the King of Kebab stand told me, proudly and unprompted, as he piled my plate with meat.

The continent’s problems are not caused by immigration or cultural politics but by economic and technological decline

Donald Trump’s new national security strategy offers a misguided assessment of Europe, long regarded as the US’s most reliable ally. Unrestrained immigration and other policies derided by administration officials as “woke”, it warns, could lead to “civilisational erasure” within a few decades.

That argument rests on a fundamental misreading of Europe’s current predicament. While the EU does face an existential threat, it has little to do with immigration or cultural politics. In fact, the share of foreign-born residents in the US is slightly higher than in Europe.

New mayor, 34, was sworn in by state attorney general Letitia James in old beaux-arts city hall subway station

Zohran Mamdani was sworn in as mayor of New York City soon after midnight in a private ceremony in an abandoned beaux-arts subway station – a prelude to daylong celebrations set to include a second, public swearing-in and a block party outside city hall.

Mamdani, 34, was sworn into office by the New York attorney general, Letitia James, surrounded by wife, Rama Duwaji, members of his immediate family, including Mira Nair, his mother and a film-maker, and his father, Mahmood Mamdani, a professor of African studies at Columbia University.

Colorado lawmaker, who pushed for Epstein files release, points to bill’s unanimous passage through US House and Senate

Republican representative Lauren Boebert has fired back at Donald Trump for vetoing a bill that would have funded a drinking water project in her Colorado district, implying the president was playing at political retaliation.

The bill was aimed at funding a decades-long project to bring safe drinking water to 39 communities in Colorado’s eastern plains, where the groundwater is high in salt and wells sometimes unleash radioactivity into the water supply.

Ex-special counsel testified in front of judiciary committee about aborted federal prosecution of Donald Trump

Jack Smith, the former justice department special counsel who led the aborted federal prosecution of Donald Trump, told a congressional committee that he never spoke to Joe Biden about his cases, according to the transcript of a deposition released on Wednesday.

In his behind-closed-doors testimony to the House judiciary committee earlier this month, Smith defended the charges he brought against Trump for allegedly possessing classified documents and attempting to overturn the 2020 election, while warning of the consequences of allowing election meddling to go unpunished.

I’ve spent six years writing about environmental justice. The uncomfortable truth is that we’re not all in it together – but people power is reshaping the fight

It’s been another year of climate chaos and inadequate political action. And it’s hard not to feel despondent and powerless.

I joined the Guardian full time in 2019, as the paper’s first environmental justice correspondent, and have reported from across the US and the region over the past six years. It’s been painful to see so many families – and entire communities – devastated by fires, floods, extreme heat, sea level rise and food shortages. But what’s given me hope during these six years of reporting as both an environmental and climate justice reporter are the people fighting to save our planet from catastrophe – in their communities, on the streets and in courtrooms across the world.

Demonstrations against deteriorating living conditions have widened to include criticism of how Iran is governed

Alborz, a textile merchant in the central Iranian city of Isfahan, decided he could no longer sit on the sidelines. He closed his shop and took to the streets, joining merchants across Iran who shuttered their stores and students who took over their campuses to protest against declining economic conditions.

The sudden loss of purchasing power pushed Alborz and tens of thousands of other Iranians into the streets, where protests are now entering their fourth day. Students have paralysed university campuses, traders have shut down their stores and demonstrators have blocked off streets in defiance of police. Protests have spread from the capital, Tehran, to cities across Iran.

Fifty-two black bears were killed in three-week hunt state officials said was necessary to reduce ursine population

Wildlife officials in Florida say the slaughter of dozens of black bears during a controversial three-week hunt this month was a success, despite the opposition of protesters who condemned the “heartbreaking, bloody spectacle”.

The Florida fish and wildlife conservation commission (FWC) on Tuesday announced that 52 bears were killed between 6 and 28 December, and promised to release a “full harvest report” in the coming months that will provide details about where and how the animals died.

Tesla endured tough year in part thanks to some consumers’ distaste for Elon Musk’s embrace of rightwing politics

Tesla has taken the unusual step of publishing sales forecasts that suggest 2025 deliveries will be lower than expected and future years’ sales will be well below targets set by its chief executive, Elon Musk.

The US electric vehicle maker published figures from analysts suggesting it will announce 423,000 deliveries during the fourth quarter of 2025, in a new “consensus” section on its investor website. That would represent a 16% decline from the final quarter of 2024.

Guardian US readers share how global heating and biodiversity loss affected their lives in ways that don’t always make the headlines

The past year was another one of record-setting heat and catastrophic storms. But across the US, the climate crisis showed up in smaller, deeply personal ways too.

Campfires that once defined summer trips were never lit due to wildfire risks. There were no bites where fish were once abundant, forests turned to meadows after a big burn and childhood memories of winter wonderlands turned to slush.

How the tech CEO and ‘Dogefather’ made a mess of the year – from an apparent Nazi salute during his White House tenure to Tesla sales slumps and Starship explosions

The year of 2025 was dizzying for Elon Musk. The tech titan began the year holding court with Donald Trump in Washington DC. As the months ticked by, one public appearance after another baffled the US and the world. Musk appeared to give a Nazi salute at Trump’s inauguration, staunchly championed a 19-year-old staffer nicknamed “Big Balls,” denied reports of being a drug addict while advising the president, and showed up at a White House press conference with a black eye – all in the first half of the year alone.

“Elon’s attitude is you have to get it done fast. If you’re an incrementalist, you just won’t get your rocket to the moon,” Susie Wiles, Trump’s chief of staff, told Vanity Fair in an expansive interview earlier this month. “And so with that attitude, you’re going to break some china.”

Environmental advocates notched key wins at local and state levels this year despite Trump rollbacks

As 2025 draws to a close, environmental advocates across the US find themselves weighing a year marked by both setbacks and successes.

Despite major environmental reversals taken by the Donald Trump administration including loosening fossil fuel rules and weakening endangered-species safeguards, conservationists, lawmakers and researchers still notched key wins at local and state levels.

In documentary I’m Chevy Chase and You’re Not, the actor and his family revealed that doctors told them to ‘prepare yourselves for the worst’

Chevy Chase suffered “near fatal” heart failure which led to him being placed in an induced coma during the pandemic in 2021, according to a new film about the American actor and comedian.

As documented in I’m Chevy Chase and You’re Not, the star of films such as Caddyshack and the National Lampoon movies, who hosted the Oscars twice, spent a total of five weeks in hospital.
