Exclusive: Guardian investigation finds AI Overviews provided inaccurate and false information when queried over blood tests

Google has removed some of its artificial intelligence health summaries after a Guardian investigation found people were being put at risk of harm by false and misleading information.

The company has said its AI Overviews, which use generative AI to provide snapshots of essential information about a topic or question, are “helpful� and “reliable�.

Exclusive: US vice-president ‘sympathetic’ to concerns over Grok-generated pornography, says deputy PM

JD Vance, the US vice-president, has agreed that it is “entirely unacceptable� for platforms such as X to allow the proliferation of AI-generated sexualised images of women and children, David Lammy has told the Guardian.

The deputy prime minister said Vance, usually known as an AI enthusiast, expressed concern about how the technology was being used to fuel “hyper-pornographied slop� online when they met in Washington on Thursday.

As synthetic personas become an increasingly normal part of life, meet the people falling for their chatbot lovers

Lamar remembered the moment of betrayal like it was yesterday. He’d gone to the party with his girlfriend but hadn’t seen her for over an hour, and it wasn’t like her to disappear. He slipped down the hallway to check his phone. At that point, he heard murmurs coming from one of the bedrooms and thought he recognised his best friend Jason’s low voice. As he pushed the door ajar, they were both still scrambling to throw their clothes on; her shirt was unbuttoned, while Jason struggled to cover himself. The image of his girlfriend and best friend together hit Lamar like a blow to the chest. He left without saying a word.

Two years on, when he spoke to me, the memory remained raw. He was still seething with anger, as if telling the story for the first time. “I got betrayed by humans,� Lamar insisted. “I introduced my best friend to her, and this is what they did?!� In the meantime, he drifted towards a different kind of companionship, one where emotions were simple, where things were predictable. AI was easier. It did what he wanted, when he wanted. There were no lies, no betrayals. He didn’t need to second-guess a machine.

The ‘put her in a bikini’ trend rapidly evolved into hundreds of thousands of requests to strip clothes from photos of women, horrifying those targeted

Like thousands of women across the world, Evie, a 22-year-old photographer from Lincolnshire, woke up on New Year’s Day, looked at her phone and was alarmed to see that fully clothed photographs of her had been digitally manipulated by Elon Musk’s AI tool, Grok, to show her in just a bikini.

The “put her in a bikini� trend began quietly at the end of last year before exploding at the start of 2026. Within days, hundreds of thousands of requests were being made to the Grok chatbot, asking it to strip the clothes from photographs of women. The fake, sexualised images were posted publicly on X, freely available for millions of people to inspect.

Labour Greater Manchester mayor says he agrees with Kemi Badenoch about need to protect under 16s

No 10 is facing renewed pressure to ban social media for under-16s after the Conservatives and the Labour mayor of Greater Manchester, Andy Burnham, supported limits to prevent harm to children.

The government is understood to have no plans for a “blanket ban� on social media use by under 16s. However, sources said it was closely monitoring the impact of moves taken to prevent children setting up accounts on Facebook, Instagram, Kick, Reddit, Snapchat, Threads, TikTok, X, YouTube and Twitch.

Nick and Brooke Shirley have for years published conspiracy-minded takes on hot-button rightwing issues

YouTube influencer Nick Shirley, whose viral video alleging fraud by daycare centers servicing Minneapolis’s Somali American community came days ahead of the Trump administration’s declaration of a national funding freeze, has for years published conspiracy-minded takes on hot-button rightwing issues.

He also has close ties to the White House, Republicans, and to representatives of an earlier generation of rightwing partisan “ambush journalists� such as James O’Keefe. He worked with Minnesota Republicans to produce the viral video on Somali-run daycares.

Some experts have voiced fears a tech meltdown could hit our savings and pensions – here’s how to protect yourself

The new year has started as 2025 ended – with share prices booming amid warnings from some that the growth is being driven by overvalued technology stocks. Fears of an “AI bubble� have been voiced by people from the governor of the Bank of England to the head of Google’s parent company, Alphabet.

Even if you have not actively invested in technology shares, the chances are you have some exposure to companies operating in the sphere. Even if you do not, a collapse could take down other companies’ values.

Each week we cut through the noise to bring you smart, practical recommendations on how to live better – from what is worth buying to the tools, habits and ideas that actually last.

At this time last year, I was a full-time student, throwing on the requisite leggings and an oversized sweatshirt for evening classes and late-night library sessions. This year, I’ve joined countless others in office life, zipping in and out of conference rooms and hopping on video calls for interviews and meetings. I love any excuse to shop, but many office-friendly pieces, including pricey blazers and crisp button-downs, are far outside my price range.

The long-running series in which readers answer other readers’ questions tackles a road safety issue

• Read this week’s replies: Can you really fake it to make it?

What’s the point of having speed limits if camera-warning signs and apps allow drivers to slow down in advance – then just continue speeding? Maybe the UK government in its new consultations on road safety should add the question of hiding speed cameras to their list of concerns. I’m a driver, but also a pedestrian and cyclist and get fed up with seeing cars zooming down local roads at way more than 20 or 30mph. There are flashing lights that tell drivers what speed they’re doing, but there’s no penalty for going over at those points. Amy, Cornwall

Zurich-based firm taps into latest robot tech to ‘fibre-spray’ high-end sports shoes worn by the likes of Roger Federer

A robot leg whirs around in a complex ballet as an almost invisible spray of “flying fibre� builds a hi-tech £300 sports shoe at its foot.

This nearly entirely automated process – like a sci-fi future brought to life – is part of the gameplan from On, the Swiss sports brand that is taking on the sector’s mighty champions Nike and Adidas with a mix of technology and chutzpah.

Swedish producer is trying to to accelerate the process of extracting the elements vital for hi-tech products

It is deep winter with temperatures dropping to -20C. The sun never rises above the horizon, instead bathing Sweden’s most northerly town of Kiruna in a blue crepuscular light, or “civil twilight� as it is known, for two or three hours a day stretching visibility a few metres, notwithstanding heavy snow.

But 900 metres below the arctic conditions, a team of 20 gather every day, forgoing the brief glimpse of natural light and spearheading the EU’s race to mine its own rare earths. Despite identification of several deposits around the continent, and some rare earth refineries including Solvay in France, there are no operational rare earth mines in Europe.

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.

• The 15 best games to play on the Nintendo Switch in 2025

This landmark role-playing game remains a revolutionary tour de force

At first glance, Final Fantasy Tactics: The Ivalice Chronicles, first released in 1997 and now available in newly remastered guise, does little to separate itself from other boilerplate fantasy fiction. There is a hero, Ramza – an idealistic nobleman with luscious blond hair who cavorts about the medieval-inspired realm of Ivalice in search of high adventure. But quickly, and with narrative elegance, the picture complicates: peasant revolutionaries duke it out with gilded monarchists; machiavellian plots plunge the kingdom into chaos. Ramza must navigate this knotty political matrix, all while experiencing his own ideological awakening.

There is a strong case to be made that Final Fantasy Tactics tells a better story than the landmark Final Fantasy VII (which saw Cloud Strife and a ragtag bunch of eco-terrorist pals taking on the shady megacorporation Shinra). And with our real-world political focus shifting from the looming threat of the climate crisis to the more pressing rise of fascism (though the two are inextricably linked), one can make the argument that Tactics is now also the more timely game.

In this week’s newsletter: Stranger Things’ climactic showdown is the latest pop culture spectacle to feel like its been ported straight from a console. The industries’ reciprocally influential relationship can be to everyone’s gain

It had begun to feel like an endurance test by the end, but nonetheless, like the sucker I am, I watched the Stranger Things finale last week. And spoiler warning: I’m going to talk about it in general terms in this newsletter. Because approximately 80% of the final season comprised twentysomething “teenagers� explaining things to each other while using random 1980s objects to illustrate convoluted plans and plot points, my expectations were not high. After an interminable hour, finally, something fun happens, as the not-kids arm themselves with machine guns and molotovs and face off against a monstrously gigantic demon-crab. Aha, I thought – the final boss battle!

The fight was like something out of Monster Hunter, all scale and spectacle with a touch of desperation. For a very long time, video games sought to imitate cinema. Now cinema (and TV) often feels like a video game. The structure of Stranger Things’ final season reminded me a lot of Resident Evil: long periods of walking slowly through corridors, with characters exchanging plot information aloud on their way to the action, and occasional explosions of gunfire, screeching monsters or car chases. Those long periods of relative inaction are much more tolerable when you’ve got a controller in your hands. I am all for TV and film embracing the excitement, spectacle and dynamism of video games, but do they have to embrace the unnecessary side-quests and open-world bloat, too?

This now venerable hardware remains an ideal platform for classics such as Minecraft and daring experiments from the brightest new developers

Whether you’re after tense psychological horror or wild escapism, it’s all here and more.
