Volunteers and new recruits come together for ‘wikithon’ to put more detail about industry into public domain

“Anyone can edit Wikipedia,” the adage goes. But, it turns out, a relatively small number actually do.

What is worthy of a digital page in the world’s largest and most-read encyclopedia is decided by roughly 270,000 active volunteers, enthusiasts who populate the online resource with information on anything from 19th-century medicine to TikTok trends. Inevitably, some subjects are sidelined – the global south, notable women – but a new batch of Wikipedian recruits are waging war on one neglected topic: the arms industry.

Last week, in a classroom in central London, two dozen volunteers huddled around laptops and free servings of vegan Ethiopian food for what is known as a “wikithon”, an event of collective and in-person Wikipedia editing. Some were veteran editors in their 70s, others young students who had never registered an account before. But their targets include subjects such as Palantir, Project Maven and Nitro-Chem.

Action needed to avoid disastrous overshoot of climate targets, according to organisation’s environment body

The world needs to cut carbon emissions by nearly a fifth in the next four years, and by close to half within a decade, to avoid overshooting climate targets by a disastrous margin.

Although the “window has closed” on holding temperature rises to 1.5C, in line with scientific advice, limiting the “overshoot” of that target is still possible, according to the UN Environment Programme (Unep).

Archaeologist says skeleton inside coffin inscribed to Valerius Amandinus is likely to be remains of 11th-century abbot

It has all the ingredients of a chilling mystery: the skeleton of an unknown man discovered within a Roman sarcophagus unearthed in the grounds of Westminster Abbey.

Now an expert has said he has solved the longstanding “who-is-it”, suggesting the remains belonged to a medieval abbot.

Marine Le Pen and Donald Trump are arsonists who play at being firefighters. Nigel Farage is finding that act harder to pull off in Andy Burnham’s Britain

An election where one side represents chaos will nearly always be won by the party that promises order instead. Public fatigue after years of turbulent Tory rule accounted for Labour’s 2024 landslide victory more than any policy in Keir Starmer’s manifesto. Across the Channel, Marine Le Pen, leader of the far-right National Rally (RN), is currently on course to win next year’s presidential poll with a pledge of “restored authority and security” for a country that has spent years cycling between enervating stasis and explosive crisis.

Le Pen has been boosted in recent days by scenes of city centres ablaze and shops being looted as student demonstrations mutated into riots. Street confrontation is a more standard feature of the political repertoire in France than in most settled democracies, but the destruction was disturbing by any measure.

A tangy mushroom stew with potato pancakes for dipping, and a rustic but versatile cabbage and mushroom soup

A thick, creamy and tangy wild mushroom stew, inspired by Belarusian mačanka and traditionally served with thick buckwheat pancakes for dipping. My version, however, features another Slovak dish in the form of lokše, which are crepes or flatbreads made with mashed potato dough. The result is so good. Then, a simple, seasonal soup made with just a handful of ingredients that captures the heart and soul of eastern European soup making. While it doesn’t belong to any single location, I hope it will taste like “home” to readers connected to the region.

Shortages caused by the country’s lack of hard currency have escalated into a national emergency, with drivers waiting for a fuel tanker that may never arrive

From the driver’s seat of his rusted minibus, Sido Sombeja stares out at a stationary sea of rear lights stretching for almost a mile down the road. It is 3am in Zomba, the old capital of Malawi, and cold night air comes through the cracked windscreen. For eight consecutive days and nights, the 40-year-old father of four has lived out of this vehicle, waiting for a fuel tanker that may never arrive.

Sombeja chews on a cold piece of fried mandazi – a doughy snack that has been the only food available. The Meru petrol station is no longer just a place of transit; it has transformed into a makeshift village of drivers in parked vehicles. In these queues, strangers form uneasy alliances. Motorists group together to guard one another’s vehicles during rare bathroom breaks, and coordinate to aggressively block any queue-jumpers. Men sleep under the bellies of trucks. They wash their faces with bottled water on the kerbside and gather around charcoal braziers (mbaula) at night.

Despite US-Israeli airstrikes and Tehran’s attacks on shipping, the waterway still has to provide a lifeline for those that live and work there

Capt Farouq turns the wheel as he watches the ferry terminal of Bandar Abbas grow smaller, its bright lights flickering in the distance.

In front of him, the navigation radar beeps periodically, its green and pink lights glowing in the darkness. The ferry, today at about half capacity with roughly 100 passengers, turns and heads into the darkness of the strait of Hormuz.

Adriana Retyte took her own life after viewing ‘high-risk’ material on the video-sharing platform TikTok

A 14-year-old schoolgirl’s death after TikTok served her suicide content has prompted renewed calls for UK watchdogs to crack down on “toxic” social media feeds.

Adriana Retyte, a pupil at Langley school in Norfolk, took her own life after she viewed videos and images related to suicide on the video-sharing platform, according to a coroner who last week found her access to the material on TikTok “may have played a significant part in her decision to take her life”.

Lula’s supporters suspect tech firm meddling on behalf of US president Donald Trump, who has close ties to Bolsonaro family

Five days after his defeat in the first round of the Brazilian presidential election, leftwing president Luiz Inácio Lula da Silva spent almost 24 hours unable to boost his Instagram posts, while his opponent, far-right senator Flávio Bolsonaro, could.

Lula’s lawyers included the episode in a list of incidents that they submitted to the electoral court and international observers as “evidence” that Meta, Instagram’s owner, was actively trying to interfere in Brazil’s election in Bolsonaro’s favour.
