Exclusive: German research into responses to health queries raises fresh questions about summaries seen by 2bn people a month

• How the ‘confident authority’ of AI Overviews is putting public health at risk

Google’s search feature AI Overviews cites YouTube more than any medical website when answering queries about health conditions, according to research that raises fresh questions about a tool seen by 2 billion people each month.

The company has said its AI summaries, which appear at the top of search results and use generative AI to answer questions from users, are “reliable� and cite reputable medical sources such as the Centers for Disease Control and Prevention and the Mayo Clinic.

Guardian found OpenAI’s platform cited Grokipedia on topics including Iran and Holocaust deniers

The latest model of ChatGPT has begun to cite Elon Musk’s Grokipedia as a source on a wide range of queries, including on Iranian conglomerates and Holocaust deniers, raising concerns about misinformation on the platform.

In tests done by the Guardian, GPT-5.2 cited Grokipedia nine times in response to more than a dozen different questions. These included queries on political structures in Iran, such as salaries of the Basij paramilitary force and the ownership of the Mostazafan Foundation, and questions on the biography of Sir Richard Evans, a British historian and expert witness against Holocaust denier David Irving in his libel trial.

Majority US-owned venture includes Larry Ellison’s Oracle, private-equity group Silver Lake and Abu Dhabi’s MGX

TikTok announced on Thursday it had closed a deal to establish a new US entity, allowing it to sidestep a ban and ending a long legal battle.

The deal finalized by ByteDance, TikTok’s Chinese owner, sets up a majority American-owned venture, with investors including Larry Ellison’s Oracle, the private-equity group Silver Lake and Abu Dhabi’s MGX owning 80.1% of the new entity, while ByteDance will own 19.9%.

This article was amended on 23 January 2026 to clarify that the new board includes a senior advisor to TPG, not a current TPG executive.

Kristalina Georgieva says research suggests 60% of jobs in advanced economies will be affected, with many entry-level roles wiped out

Artificial intelligence will be a “tsunami hitting the labour market�, with young people worst affected, the head of the International Monetary Fund warned the World Economic Forum on Friday.

Kristalina Georgieva told delegates in Davos that the IMF’s own research suggested there would be a big transformation of demand for skills, as the technology becomes increasingly widespread.

US aerospace tech company reportedly held talks last year over private share sale that values business at $800bn

Elon Musk’s SpaceX is reportedly lining up four Wall Street banks to help the company list on the stock market as investors prepare for an expected rush of US tech listings.

SpaceX is considering Bank of America, JP Morgan, Goldman Sachs and Morgan Stanley for leading roles in an initial public offering, according to the Financial Times and Reuters.

Misinformation technology could be deployed at scale to disrupt 2028 US presidential election, AI researchers say

Political leaders could soon launch swarms of human-imitating AI agents to reshape public opinion in a way that threatens to undermine democracy, a high profile group of experts in AI and online misinformation has warned.

The Nobel peace prize-winning free-speech activist Maria Ressa, and leading AI and social science researchers from Berkeley, Harvard, Oxford, Cambridge and Yale are among a global consortium flagging the new “disruptive threat� posed by hard-to-detect, malicious “AI swarms� infesting social media and messaging channels.

OpenAI, Anthropic, SpaceX and Stripe are rumoured to be among ten of the biggest companies considering IPOs

You’ve probably heard of “unicorns� – technology startups valued at more than $1bn – but 2026 is shaping up to be the year of the “hectocorn�, with several US and European companies potentially floating on stock markets at valuations over $100bn (£75bn).

OpenAI, Anthropic, SpaceX and Stripe are among the big names said to be considering an initial public offering (IPO) this year.

Experts say tool can give ‘completely wrong’ medical advice which could put users at risk of serious harm

• AI Overviews cite YouTube more than any medical site, study suggests

Do I have the flu or Covid? Why do I wake up feeling tired? What is causing the pain in my chest? For more than two decades, typing medical questions into the world’s most popular search engine has served up a list of links to websites with the answers. Google those health queries today and the response will likely be written by artificial intelligence.

Sundar Pichai, Google’s chief executive, first set out the company’s plans to enmesh AI into its search engine at its annual conference in Mountain View, California, in May 2024. Starting that month, he said, US users would see a new feature, AI Overviews, which would provide information summaries above traditional search results. The change marked the biggest shake-up of Google’s core product in a quarter of a century. By July 2025, the technology had expanded to more than 200 countries in 40 languages, with 2 billion people served AI Overviews each month.

Partnership with tech giant speaks to push to engage younger fans but also has wider strategic goals in mind

In this World Cup year, Fifa has come out of the blocks quickly. In the past few weeks any number of initiatives have been announced or activated, from a data partnership with Opta to facilitate more betting, to the Fifa Pass for speeding up visa applications for the US this summer, to the unveiling of the official Lego World Cup trophy. Among the ever-expanding list is an intriguing deal with TikTok, a partnership that will give digital creators front-row seats at the 104-match tournament.

In Fifa language its partnership with the short-form video platform will make “the most inclusive event in football history … even more accessible�. According to TikTok’s global head of content, James Stafford, it will bring fans “closer to the action in ways they can’t get anywhere else�. It plans to do so by granting an unspecified number of online personalities behind-the-scenes access, giving them archive and highlights footage to use in their content and, in return, requesting an avalanche of posts that will make the World Cup inescapable for TikTok users.

Politicians call for more infrastructure funding amid anger that county is seen as ‘holiday playground’

Accessed by a steep, winding lane, the tiny settlement of Cucurrian in the far-west of Cornwall feels remote at the best of times. But over the last two weeks, the people who live here have felt even more isolated after they were left without a way of communicating with the outside world as a result of Storm Goretti.

“I think people feel let down, angry, failed,� said Mark Pugh, an audiobook producer, who has spent more hours than he would care to tot up carefully picking his way out of Cucurrian and sitting in his car in a layby to find a mobile signal good enough to work from. “This storm has shown that Cornwall isn’t resilient enough. A lot is promised, but not enough is delivered.�

AI evangelist Peter Kyle wants to scale up businesses, attract overseas investors and look out for UK’s poorer regions

The UK business secretary, Peter Kyle, has said he is “betting big� and “picking winners� as the government takes direct stakes in growing businesses to boost economic growth.

Speaking at the World Economic Forum in Davos, where he and the chancellor, Rachel Reeves, have been talking up Britain’s prospects, Kyle said ministers were taking an “activist� approach to industrial policy.

Book-style Android with cutting-edge AI, good cameras and great tablet screen for media and multitasking on the go

Google’s third-generation folding phone promises to be more durable than all others as the first with full water and dust resistance while also packing lots of advanced AI and an adaptable set of cameras.

The Pixel 10 Pro Fold builds on last year’s excellent 9 Pro Fold by doing away with gears in the hinge along its spine allowing it to deal with dust, which has been the achilles heel of all foldable phones until now, gumming up the works in a way that just isn’t a problem for regular slab phones.

Standard iPhone levels up to Pro models with big screen upgrade, double the storage and more top features than ever

It may not look as different as the redesigned Pro models this year or be as wafer thin as the new iPhone Air, but the iPhone 17 marks a big year for the standard Apple smartphone.

That’s because Apple has finally brought one of the best features of modern smartphones to its base-model flagship phone: a super-smooth 120Hz screen.

Screen: 6.3in Super Retina XDR (120Hz OLED) (460ppi)

Processor: Apple A19

RAM: 8GB

Storage: 256 or 512GB

Operating system: iOS 26

Camera: 48MP main + 48MP UW; 18MP front-facing

Connectivity: 5G, wifi 7, NFC, Bluetooth 6, Thread, USB-C, Satellite, UWB and GNSS

Water resistance: IP68 (6 metres for 30 mins)

Dimensions: 149.6 x 71.5 x 7.95mm

Weight: 177g

Ultra-slim and light smartphone feels special, but cuts to camera and battery may be too hard to ignore for most

The iPhone Air is a technical and design marvel that asks: how much are you willing to give up for a lightweight and ultra-slender profile?

Beyond the obvious engineering effort that has gone into creating one of the slimmest phones ever made, the Air is a reductive exercise that boils down the iPhone into the absolute essentials in a premium body.

First new design in ages, upgraded camera, serious performance and longer battery life make it a standout year

The 17 Pro is Apple’s biggest redesign of the iPhone in years, chucking out the old titanium sides and all-glass backs for a new aluminium unibody design, a huge full-width camera lump on the back and some bolder colours.

That alone will make the iPhone 17 Pro popular for those looking to upgrade and be seen with the newest model. But with the change comes an increase in price to £1,099 (€1,299/$1,099/A$1,999), crossing the £1,000 barrier for the first time for Apple’s smallest Pro phone, which now comes with double the starting storage.

Cut-price watch offers most of what makes the Series 11 great, including an always-on screen, watchOS 26 and wrist-flick gesture

Apple’s entry level Watch SE has been updated with almost everything from its excellent mid-range Series 11 but costs about 40% less, making it the bargain of iPhone smartwatches.

The new Watch SE 3 costs from £219 (€269/$249/A$399), making it one of the cheapest brand-new fully fledged smartwatches available for the iPhone and undercutting the £369 Series 11 and the top-of-the-line £749 Apple Watch Ultra 3.

Camera-equipped sports shades have secure fit, open-ear speakers, mics and advanced Garmin and Strava integration

The Oakley Meta Vanguard are new displayless AI glasses designed for running, cycling and action sports with deep Garmin and Strava integration, which may make them the first smart glasses for sport that actually work.

They are a replacement for running glasses, open-ear headphones and a head-mounted action cam all in one, and are the latest product of Meta’s partnership with the sunglasses conglomerate EssilorLuxottica, the owner of Ray-Ban, Oakley and many other top brands.

Third-gen watch adds 5G, satellite SOS and messaging, a bigger screen and longer battery life in same rugged design

The biggest, baddest and boldest Apple Watch is back for its third generation, adding a bigger screen, longer battery life and satellite messaging for when lost in the wilderness.

The Ultra 3 is Apple’s answer to adventure watches such as Garmin’s Fenix 8 Pro while being a full smartwatch for the iPhone with all the trimmings. As such, it is not cheap, costing from £749 (€899/$799/A$1,399) – £50 less than 2023’s model – sitting above the £369-plus Series 11 and £219 Watch SE 3.

Top adventure watch upgraded with 4G calls, messages, live tracking, satellite texts and SOS for going off the grid

The latest update to Garmin’s class-leading Fenix adventure watch adds something that could save your life: phone-free communications and emergency messaging on 4G or via satellite.

The Fenix 8 Pro takes the already fantastic Fenix 8 and adds in the new cellular tech, plus the option of a cutting-edge microLED screen in a special edition of the watch. It is Garmin’s top model and designed to be the only tool you need to more-or-less go anywhere and track anything.

Video game publisher to cancel Prince of Persia remake and close studios after several difficult years

The video game publisher behind the Assassin’s Creed series has cancelled six projects including a remake of Prince of Persia: The Sands of Time as it fights to stay competitive in the global gaming market.

Ubisoft announced a sweeping reorganisation and said it would cancel six games, sending its shares to their lowest level in more than a decade on Thursday.

Quake Brutalist Jam began as a celebration of old-fashioned shooter level design, but its latest version is one step away from being a game in its own right

A lone concrete spire stands in a shallow bowl of rock, sheltering a rusted trapdoor from the elements. Standing on the trapdoor causes it to yawn open like iron jaws, dropping you through a vertical shaft into a subterranean museum. Here, dozens of doors line the walls of three vaulted grey galleries, each leading to a pocket dimension of dizzying virtual architecture and fierce gladiatorial combat.

Welcome to Quake Brutalist Jam, the hottest community event for lovers of id Software’s classic first-person shooter from 1996. First run in 2022, the Jam started out as a celebration of old-school 3D level design, where veteran game developers, aspiring level designers and enthusiast modders gather to construct new maps and missions themed around the austere minimalism of brutalist architecture.

After years away​ revisiting my abandoned island uncovers new features, old memories and the quiet reassurance that ​you can go home again

• Don’t get Pushing Buttons delivered to your inbox? Sign up here

Nintendo’s pandemic-era hit Animal Crossing: New Horizons got another major update last week, along with a £5 Switch 2 upgrade that makes it look and run better on the new console. Last year, I threw a new year’s party for my children in the game, but apart from that I have barely touched my island since the depths of lockdown, when sunny Alba was my preferred escape from the monotonous misery of the real world. Back then, I spent more than 200 hours on this island. Stepping out of her (now massive) house, my avatar’s hair is all ruffled and her eyes sleepy after a long, long time aslumber.

I half-expected Alba to be practically in ruins, but it’s not that bad. Aside from a few cockroaches in the basement and a bunch of weeds poking up from the snow, everything is as it was. The paths that I had laid out around the island still lead me to the shop, the tailors, the museum; I stop by to visit Blathers the curatorial owl, and he gives me a new mission to find a pigeon called Brewster so that we can open a museum cafe. “It’s been four years and eight months!� exclaims one of my longtime residents, a penguin called Aurora. That can’t be right, can it? Have I really been ignoring her since summer 2021? Thankfully, Animal Crossing characters are very forgiving. I get the impression they’ve been getting along perfectly fine without me.

The UK game developer’s latest is a database mystery constructed from an archive of fictional books. Their combined contents threaten to crack the code of reality

Bletchley Park: famed home of the Enigma machine, Colossus computer, and, according to the premise of TR-49, an altogether stranger piece of tech. Two engineers created a machine that feeds on the most esoteric books: treatises on quantum computing, meditations on dark matter, pulp sci-fi novels and more. In the mid-2010s, when the game is set, Britain finds itself again engulfed by war, this time with itself. The arcane tool may hold the key to victory.

You play as budding codebreaker Abbi, a straight-talking northerner who is sifting through the machine now moved to a crypt beneath Manchester Cathedral. She has no idea how it works and neither do you. So you start tinkering. You input a four-digit code – two letters followed by two numbers. What do these correspond to? The initials of people and the year of a particular book’s publication. Input a code correctly and you are whisked away to the corresponding page, as if using a particularly speedy microfiche reader. These pages – say, by famed fictional physicist, Joshua Silverton – are filled with clues and, should you get lucky, further codes and even the titles of particular works. Your primary goal is to match codes with the corresponding book title in a bid to find the most crucial text of all, Endpeace, the key to understanding the erudite ghosts of this machine.
