Data suggests firms are turning away from CEST as critics say it fails to reflect recent court rulings

Use of HMRC’s own tool for checking compliance with the UK’s controversial IR35 freelancer tax rules has fallen sharply, according to Freedom of Information data obtained by tax adviser IR35 Shield.

The Check Employment Status for Tax tool, better known as CEST, was created to help firms decide whether contractors should be taxed like employees. But usage fell 43 percent during the 2025-26 tax year, and dropped 71 percent between 2023-24 and 2024-25, from 458,894 determinations to 135,178.

The findings suggest that firms continue to abandon CEST in favor of alternative status assessment solutions and more comprehensive compliance processes, IR35 Shield said.

CEO Dave Chaplin said: “The majority of firms we speak to for the first time are either lifting blanket bans or seeking to move away from using CEST, having realized it is not compulsory to use, nor does it give them the level of certainty they need.”

The decline is not the result of changes to the tool or legislation, according to IR35 Shield.

“The underlying CEST logic has not been updated since November 2019 and was based on HMRC’s view of the law at that time. Despite the courts dismissing HMRC’s position in key areas, upon which the tool was based, the tool has not been updated,” Chaplin said.

IR35 Shield pointed out that HMRC lost a recent employment status case with Professional Game Match Officials Limited (PGMOL). Entering the facts of the case into CEST would have produced an indeterminate result, it said.

In 2022, the Public Accounts Committee Committee (PAC) found that central government was spending hundreds of millions of pounds to cover tax owed for individuals wrongly assessed as self-employed. “Government departments and agencies owed, or expected to owe, HMRC £263 million in 2020-21 due to incorrect administration of the rules,” the House of Commons spending watchdog said.

Part of the compliance problem was down to HMRC’s guidance and the CEST tool. “Some questions within CEST were difficult to interpret correctly, and the guidance was long, too general in scope and not integrated into CEST itself,” the PAC said.

In a statement sent to The Register, a spokesperson at HMRC, said: 

“We always expected use of the tool to reduce as employers familiarised themselves with the 2021 off-payroll working reforms, and the majority of those who use the tool are satisfied with the service they receive.

“The tool is rigorously tested against case law and we’ll stand by the tool’s results, so long as the information provided is correct in accordance with our guidance.” ®

Polymarket has been paying online creators to post deceptive videos that show them making lucrative bets on the prediction market, according to a new investigation in the Wall Street Journal.

The WSJ said that it analyzed 1,100 videos about Polymarket and also viewed instructional materials that the company provided to creators. Many of those videos were reportedly filmed on “near-perfect copies” of the Polymarket website, while featuring trades and winnings that were not real. The creator videos were then amplified by a “social-media army” deployed by a marketing contractor.

The WSJ said the company also told those creators not to specify that they’d been paid by Polymarket, although the creators started adding “@polymarket partner” to their bios after journalists began asking questions.

Razeen Khan, a college student and creator who worked with Polymarket until March, compared the practice to commercials that make fast food look more appealing than it is in real life: “We’re depicting what actually happens.”

Polymarket said it is “committed to maintaining accurate, fair, and transparent markets” and plans to conduct an audit of its promotional content.

Access to safe drinking water remains a challenge for billions of people worldwide, but a new invention from researchers in South Korea could make the process much simpler. A self-powered floating capsule that fits in the palm of a hand can reportedly test water quality and disinfect unsafe water without relying on batteries, external power, or chemical treatments.

A simple shake is all this water purification capsule needs

According to a recent paper published in Nature Water, the device, called the Floating-induced Detection-Guided Disinfection (FDGD) capsule, generates electricity when shaken. An internal magnet moves through a coil to produce enough power to activate a built-in sensor that measures the water’s electrical conductivity, giving users an indication of its quality through a connected smartphone or smartwatch.

If the water passes the initial safety check, the capsule can simply be left floating inside it. Gentle movement from waves or even walking while carrying the container generates static electricity, powering microscopic nanorods on the capsule’s surface. These create strong electrostatic forces that damage the membranes of nearby bacteria and viruses through a process known as electroporation, effectively neutralizing them without adding chemicals.

In laboratory testing involving containers holding up to four liters of water, researchers reported that the device successfully inactivated 99.9999% of bacteria and viruses, including E. coli, across multiple water samples. The technology was detailed in the journal Nature Water, with researchers describing it as an affordable, decentralized solution for regions where conventional water treatment infrastructure is unavailable.

The clever part isn’t the disinfection, it’s the lack of dependencies

Interestingly, plenty of portable water purifiers already exist, but most depend on disposable filters, chemicals, UV lamps, or rechargeable batteries. This capsule sidesteps all of those requirements by harvesting energy from simple physical movement, making it particularly attractive for disaster relief, camping, remote communities, or humanitarian deployments where electricity isn’t guaranteed.

Of course, the FDGD capsule is still a research prototype and has yet to prove itself outside controlled testing. But if it can be commercialized at the low cost envisioned by its creators, it could put a reliable water testing and purification tool into millions of hands. Sometimes, the biggest breakthroughs aren’t massive treatment plants or billion-dollar infrastructure projects. Sometimes, they’re small enough to fit in your pocket.

• Fraunhofer introduces quantum random generator targeting future cryptographic security challenges
• Q-Dice uses vacuum fluctuations instead of software algorithms for randomness
• New system delivers over 4 Gbit/s quantum-generated random number output

As concerns grow about the security implications of future quantum computers, researchers continue searching for stronger sources of cryptographic protection.

One critical requirement involves generating truly unpredictable random numbers that can withstand increasingly sophisticated attacks against modern digital systems.

It’s no secret that Snap has been working on a pair of AR-powered smart glasses for quite some time now – the dev kits for the hardware have been available for the past few years, and CEO Evan Spiegel always claimed that they’d be available by the end of 2026.

Well, we’ve just had our first official look at the super high-tech Specs – specs that Snap spent literally billions of dollars on over years of R&D – ahead of release later this year and, let’s just say, reactions are… mixed. 

There’s no getting around it; the glasses don’t look as sleek or as stylish as many were expecting, especially with companies like Meta and Ray-Ban coming out with some pretty slick-looking (albeit comparatively basic) smart specs. It’s actually the opposite; the glasses are massive, chunky and look overly large on the head – even when modelled by Spiegel on stage at the announcement.

As you’d expect, the reaction memes are strong, and opinions are divided online. Even Snap’s stock dropped by 5% after the announcement, suggesting that Snap might’ve been drinking its own kool-aid for a little too long, focusing too much on the smarts and not the fact that, y’know, these actually need to be worn, in public, where people can actually see them on your face. 

The problem is that I know the software experience on the Specs is fantastic, unlike anything else I’ve ever seen or used – but will people actually give it a go when they look like that? I think we all know the answer to that question.

Snap’s software is leagues ahead of the competition

Back in September 2025, I got to try the Spects dev kit at Snap’s London HQ, and Snap OS 2.0 feels closer to the sci-fi AR we were promised a decade ago than anything I’ve used since. While most rivals are serving up green, single‑colour overlays and static notification panels, Snap is running a full operating system that understands the world around you.

Full‑colour graphics aren’t just floating in your periphery; they’re anchored to real objects and surfaces. Pin a window next to your desk or drop a widget onto a coffee table and it stays there, even as you look or walk away. It sounds like a small thing, but that persistence makes the specs feel like genuine mixed‑reality interfaces rather than glorified heads‑up displays.

Then there’s the built-in AI, which, believe it or not, is actually quite good. Much like Google Gemini’s Live Mode on mobile, Snap’s Spatial Tips feature doesn’t just answer questions in a floating chat box; it understands what you’re looking at and overlays help directly onto it.

When I asked how to do an ollie on a skateboard, it didn’t spit out a wall of text – it drew the steps onto the board itself, showing where my feet should go at each stage. The same approach applies to things like flat‑pack furniture, car engines or household repairs: you look at the thing you’re stuck on, and the instructions appear right where you need them.

On top of that, real‑time translation features can caption conversations and translate signs or menus with real-world overlays, with text that sticks to people and objects as they move. Compared to the mostly static, widget‑driven software on Even Realities’ G2 or Rokid’s AR specs, Snap OS 2.0 feels way more polished, mature and genuinely useful.

So when I say Snap’s software is leagues ahead of the competition, I really do mean it.

Comparing the Snap Specs to existing smart glasses like the Meta Display specs and Even Realities G2 is like comparing an iPhone 17 Pro to a Nokia 3410; they’re in totally different leagues.

In fact, in terms of the tech and mixed-reality experience on offer, they’re closer to the likes of the Apple Vision Pro and Samsung Galaxy XR – relatively large VR-style headsets that you certainly couldn’t wear on a night out or a trip – than existing smart glasses.

Like the proper headsets, Snap’s specs have high-end full-colour screens rather than the single-colour panels used by most existing manufacturers, and like those headsets, it can run a plethora of first- and third-party apps – there’s a reason why Snap got those dev kits out so early, after all.

It actually goes a step further with its semi-transparent lenses, rather than using passthrough camera feeds and regular screens like the existing ultra-premium headsets. With electrochromic dimming on the lenses, it’s not hard to imagine they could offer a more immersive mode for watching movies and the like. 

When you look at the Specs through that lens (pun intended), they look more like a phenomenal feat of engineering than a bulky pair of smart glasses.

… but there’s no argument, they’re ugly and expensive

Snap has tried its best to frame these as fashionable, collaborating with the likes of Kaia Gerber, Jimmy Butler, Imogen Heap, Jack Harlow, and Hoyeon to model the Specs in marketing images – but, let’s be honest, they’re still some pretty ugly. 

Compared to regular glasses that most people currently wear, these are much thicker – not just in the frame housing the screens but also in the arms of the glasses. The arms also look way longer than they should – on Spiegel’s head at the reveal, anyway – with very little in terms of a hook at the end to wrap around your ear for extra stability.

The slightly rounded, curved shape of the specs is quite nice in my eyes, but they’re just too big, chunky and obviously-smart to be worn by the average Joe. And with an eye-watering price tag of £1,995/$2,195, they’re not attainable for the average consumer either.

Of course, these are first-gen specs, and if Snap does power through and keep iterating on the design and hardware, this is the worst the Specs will ever be.

Just think about how much better the Apple Watch Series 11 is compared to the Apple Watch – it’s the same here. The core concept is there, and Snap’s software is a shining beacon in a sea of lazy AR concepts; it just needs the time to properly cook. 

That said, I reckon the Snap Specs will be a big hit with die-hard techies with money to burn, and I imagine I’ll be seeing execs from companies sporting the Specs at events like MWC in 2027 – but will I see anyone actually wearing them in day-to-day life? I doubt it, and that’s a shame.
