Not to be outdone by his one-time rival, Sonic’s new racing game takes the fight to Mario with genuinely surprising mechanics we've not seen before in the genreTech20:00, 07 Jun 2025Where will you end up?Who doesn’t love a kart racer? The trouble is, they’ve started to fall into a pretty staid rhythm now. You battle it out for lap one, everything sort of settles down in lap 2, and then lap 3 can be similarly formulaic if you don’t get hit by a power-up or two.While Nintendo Switch 2's launch title Mario Kart World has moved to change this with a system that links tracks together, iconic hedgehog Sonic is doing something a little different with his return to karting.‌Not only does it make for much more chaotic racing, but there’s more going on under the hood than it first seems.‌Tracks are varied, making jumping from one to the other very excitingSonic Racing CrossWorlds initially starts off like most other kart racers. Players pick their character from a starting roster of 23 characters, pick their vehicle, and then head off.And, while the first lap plays out as you’d expect, whoever is winning gets to pick lap 2’s location, meaning racers drive through a Travel Ring and end up on a different track, before coming back for lap 3.Article continues belowGetting ahead of another vehicle so you can pick a track you know better for the next stage of the race is great, as are the ‘Rival’ you’ll be assigned at the start of each Grand Prix.Not only do these racers react more aggressively to you, but they’ll also offer unique dialog when you appear out of nowhere to overtake them, hit them with an item, or fall behind the pack.This track sees you travel through a Dragon‌Once the Grand Prix is done, there’s a chance to secure further points by racing across each track from the prior Grand Prix in a sort of three-lap sprint.In my limited playtime, I was locked alongside my rival for points before pulling out the win thanks to that final spring.More competitive racers may baulk at such randomness creeping into tracks they’ve rehearsed, but it’s a breath of fresh air for the genre and stops those middle laps feeling too predictable.‌Each vehicle can be customised furtherAside from the Travel Rings, it doesn’t hurt that Sonic Racing CrossWorlds is a fantastic racer in its own right.Drifting to earn a boost and pulling off tricks to zip past rivals is great fun, although it did take a moment to knock me out of my Mario Kart muscle memory.‌Vehicles fall into a variety of categories, and each has customisable paint jobs, too, letting you make each feel bespoke. Want a purple car for Big the Cat? Go for it. Looking to add some colour to Shadow’s vehicle? You can do it.There are also gadgets you can use to tie into your playstyle, like hoovering up rings from further away, or simply improving your smallest boost.Is it a bird? Is it a plane? No, it's a hedgehog with a driver's licence!‌The game also brings back the “Land, Sea, and Air” transformation modes for vehicles, meaning one minute you’re driving, then sailing, and then flying.The latter is particularly enjoyable, letting your character of choice navigate jump hoops and tight turns, while there are secrets to find throughout each track to encourage replayability.Sonic’s video games feel like they’re in a pretty good spot at the moment, and CrossWorlds looks to be another fine addition.Article continues belowMuch will hinge on how fun its tracks are, but early signs are very, very promising that this will be a racer that shakes up the genre just as well as anyone else can.Previewed on PS5.

So, you’ve braved the pre-order sites, or maybe you’ve just gotten lucky while waiting in line—either way, you’ve got yourself a Nintendo Switch 2. Congratulations! But before you start gaming, there are a few things you’ll need to keep in mind while setting up your console. Nintendo is known for being user friendly, but also a bit particular. Case in point: You can only do a full transfer of your Switch 1 data to your Switch 2 during setup, and if you miss this opportunity, you’ll have to reset your device to try again, or manually copy over your games and save data piece-by-piece later on.Luckily, I’ve got your back. Read on for a quick guide on how to set up your Nintendo Switch 2, and the three other features you should set up before you start playing.How to start setting up a Nintendo Switch 2For the most part, setting up a new Switch 2 out of the box is straightforward, but you’ll still want to pay close attention to each step before moving on, especially when it comes to transferring console data.First, remove your Switch 2 and your joy-con controllers from their packaging. Then, plug your joy-cons into their respective slots (they’ll attach magnetically, so it’s much simpler than on the first Switch). If you don’t know which joy-con goes where, the one with red highlights goes to the right of the screen, and the one with blue highlights goes to the left.Next, plug your Switch into power using the included charging brick and cable, and power it on. On the screens that follow, select your language and region, then read and accept the end-user license agreement. Credit: Michelle Ehrhardt You’ll see a screen to connect to the internet and download the console’s day-one system update. This technically isn’t mandatory, and skipping it (with the X button on the right joy-con) will instead take you to time zone settings. However, most features will be locked down, including backward compatibility, until you download it, so I recommend doing it during setup if possible. If you do skip this step, you can access the update later under Settings > System > System Update.Once you’re connected to the internet and you’ve started downloading the update, you’ll be able to continue setup while it downloads. Now, you’ll pick your time zone and click through a couple of tutorial pages. These will instruct you about portable and TV play, tell you how to use the kickstand and extra USB-C port, and walk you through detaching your joy-con from the console (press in the button on the back of the joy-con, underneath the trigger, and pull). You can also click through an optional tutorial on connecting your Switch 2 to a TV, if you like, after which you’ll get quick guides on using the included joy-con grip accessory and the joy-con wrist straps.If your console hasn’t finished updating, it’ll finish that now, and then take you to your first big decision: do you want to transfer your Switch 1 data to your Switch 2?Transferring Switch 1 data to the Switch 2During Switch 2 setup, Nintendo will allow you to transfer your Switch 1 data to your Switch 2, but there are a few caveats.You’ll know you’re ready for this once your system update is downloaded and you’re on a screen that says “To Nintendo Switch Console Owners,” above a graphic of someone holding a Switch 1 and Switch 2. Next to the graphic, you’ll see two buttons: Begin System Transfer, Don’t Transfer Data, plus a third button below that explains the process to you, but leaves out a few key details.Before you make your decision, the most important thing to remember is this: There are actually two ways to transfer data from the Switch 1 to the Switch 2, and despite what you might have read elsewhere, locally transferring your Switch 1 data to the Switch 2 during setup will not factory reset your original Switch. Unless you’ve taken extra steps beforehand, this is the option Nintendo’s setup process will recommend to you, so most users don’t need to be scared about accidentally erasing their original consoles. Credit: Michelle Ehrhardt If you stick with a local transfer, it will simply copy over your data to your Switch 2, so that it exists on both systems. There are a few specific cases where some data will get removed from your original device as it makes its way over to your new one, but for the most part, you’ll be able to keep using your original device as usual after the transfer, and there are ways to get that data back later on (I’ll get into that). Just know that save data for specific games, as well as some free-to-play games, may have been deleted from your Switch 1 and moved over to your Switch 2. Don’t worry— Nintendo will warn you about which software will be affected during the transfer process. Additionally, screenshots and video captures stored on a microSD card attached to the Switch 1 will need to be moved over manually later on.How to transfer your Switch 1 data locallyWith that in mind, if you want to transfer your data locally, which is what most people should do, click the Begin System Transfer button and follow the instructions—this involves signing into your Nintendo account, keeping your original Switch powered on and in close proximity to the Switch 2, and activating the transfer on your original Switch under Settings > System Settings > System Transfer to Nintendo Switch 2.How to transfer your Switch 1 data using Nintendo's serversThe confusion about factory resets comes from this data transfer option, which involves using the Nintendo servers. This will factory reset your Switch, and is best if you plan to sell it anyway, or if you expect to be away from your original Switch during Switch 2 setup and don’t mind setting up your original console from scratch when you get back to it. To start this kind of transfer, power on your original Switch, navigate to the System Transfer page mentioned above, then select I don’t have a Nintendo Switch 2 yet. Take note of the Download Deadline for later. Conveniently, that does point to one upside to this method: you can start it before you even have a Switch 2 in hand.Now, click Next, then Upload Data, then OK, followed by another OK. Click Start Initialization to begin factory resetting your original Switch. From here, your original Switch will revert to how it was before you bought it, and you’ll need to move over to your Switch 2, click Begin System Transfer, and sign into your Nintendo account. If the system detects that you have transfer data to download from the cloud, it’ll walk you through the process. Note, however, that if you don’t download your transfer data before the deadline you jotted down earlier, you’ll lose access to it.If you want to skip the data transfer process...If you’d rather not transfer your data, that’s also fine, but you won’t have an opportunity to do so later, and will instead need to move games and save data over manually. Click the Don’t Transfer Data button, then Continue to move to the next step.Adding a user and parental controlsWith system transfers out of the way, you’re through the hardest part of setting up your new console. Now, you’ll be prompted to add a user to the system. Here, you can sign in with your Nintendo Account to get access to your Switch Online subscription and your collection of downloadable games, or create a local user profile. After that, you can add more users as you like, or you can save that for later (simply navigate to System Settings > User > Add User).Next up, parental controls. Like with additional users, you can set these up later under System Settings > Parental Controls, but there’s no harm to setting them up now as well. To do so, click Set Parental Controls.  Credit: Michelle Ehrhardt You’ll have a few options. Most of these will prompt you to use Nintendo’s Parental Controls app, but you can also click the X button on the right-hand joy-con to set up limited parental controls directly on the console. Doing so will allow you to select from a number of presets that will block access to certain games and communication features, but not much else. Using the app, meanwhile, will let you set a daily play time limit, bedtime settings, restrictions on the new GameChat feature, and see reports on play time and games played. It also doesn’t require a Switch Online subscription, so it’s worth using if you have a smart device.To set up parental controls using the app, first download it for either iOS or Android using the information on the screen, then click the “If You’ve Already Downloaded the App” button. Enter the registration code from your app into your Switch 2 system, then follow the instructions in the app to finish setup. Which buttons you’ll need to click will depend on the controls you’d like to activate, as well as for which users and systems, but it’s fairly straightforward.MicroSD card limitationsJust a couple more screens. First, a quick warning about microSD cards. Unlike the Switch 1, the Switch 2 is only compatible with microSD Express cards, which are faster, but options for them are also a bit more limited—in other words, there’s a good chance you won’t be able to use the same microSD card from your Switch 1 on your Switch 2. To use a microSD card on Switch 2, it’ll need either of the two logos shown in the image below. A bit of a bummer, but at least a microSD card is optional (it’ll help you store more games, but the included storage on the Switch 2 is more generous than on the Switch 1). Credit: Michelle Ehrhardt Oh, and like on the Switch 1, the microSD slot is hidden under the kickstand, in case you’re having trouble finding it.Virtual Game CardsYou’re technically through setup at this point, but there are still a few features you’ll probably want to configure before you start gaming. The most obvious of these is Virtual Game Cards, Nintendo’s new system for managing games purchased digitally.Essentially, like the name implies, these work similarly to physical game cards, but over the internet. This means that, unlike with your Steam library, you can only load a game to one console at a time. "Loading" is Nintendo specific term, but for the most part, it just means your game is downloaded and ready to play."(Technically, you can still play the same game on two separate consoles at the same time, even if it isn't loaded on one, but doing so is a bit obtuse—click through here for more details.)To access your Virtual Game Cards, click the Virtual Game Card icon in the bottom row on your Switch 2’s home screen—it’ll look like a game cartridge. From here, if you’ve signed into your Nintendo account, you’ll see all your digital purchases and will be able to download and play them from here. If you haven’t signed into your Nintendo Account, you’ll have the option to do so. Credit: Michelle Ehrhardt Now, you’ll have a few options. First, if a game isn’t loaded onto your original Switch, you can simply download it to your Switch 2 by clicking Load to This Console. If the console isn’t set as your primary device (likely the case if you didn’t do a transfer), you might see a warning if you try to open a game, depending on how up-to-date your original Switch's software is. If your original Switch doesn't have the Virtual Game Cards update yet, you can click the If You Don’t Have That Console button to download your game anyway. It will simply cease being playable on the other console while you use it on this one, although that’s always the case when moving a Virtual Game Card between systems. Otherwise, you might need to link your two systems by bringing them close together and following the instructions on screen before you can load a Virtual Game Card on your new device. If you're not able to do this, like if you've gotten rid of your original Switch while it's still set as your primary device, you can remove your old Switch from your account by deregistering it. After deregistering your old console, you can set your Switch 2 as your new primary device by connecting it to the eShop. If you're able to link your old console to your new one, this won’t be necessary for simply accessing your library, but it will extend any Nintendo Online benefits to all users on your new primary device, rather than the one associated with your Nintendo Account. Credit: Michelle Ehrhardt Alternatively, if you've managed to link your devices, you can use the device that currently has your Virtual Game Card (i.e. your Switch 1) on it to load it to your new one (i.e. your Switch 2). Simply open your games, click Load to Another Console, and follow the instructions on screen. This will have the same effect as the Load to This Console Button. Also, if you'd like to be able to continue playing a game on a device even after moving its Virtual Game Card to another device, you can enable Use Online License under System Settings > User Settings > Online License Settings to do just that. You'll need to be connected to the internet for this to work, whereas you can play a Virtual Game Card offline, but it's better than nothing. Plus, this enables that workaround from earlier in this section that allows you to play the same game on both devices at once.How to lend a Virtual Game Card to someone elseYou’ll also notice that you can lend a Virtual Game Card to members of a “Family Group.” To do this, you’ll first need to set up a Family Group online. On Nintendo’s website, log into your Nintendo Account, then click the Family Group tab on the left hand side of your account page. Here, you can invite members to join your Family Group via email, or create a Family Group account for your child. Note that if you have a Nintendo Switch online Family Plan subscription, members of your Family Group will be able to use its benefits (for up to eight accounts), although accounts that are part of your family group can also still use their individual subscriptions.With a Family Group set up, on the Virtual Game Card page, click the game you’d like to lend out, then Lend to a Family Group Member. Next, bring your Switch 2 in close proximity with that Family Group Member’s device—this needs to be done in person.Finally, click Select a User to Lend to. You can lend up to three games to three different accounts at once, and borrowers will be able to play these games for 14 days. During that time, you won’t be able to play the Game Card, and the borrower won’t get access to your save data while borrowing. However, they will keep their own save data for their next borrowing period, or if they choose to buy the game themselves. There are no limits to how often you can lend out a game, and you can re-lend games immediately upon the borrowing period expiring. Also, while you’ll need to lend out your games in person, they’ll return to you remotely.Transferring save dataEven if you didn’t transfer your Switch 1 data to your Switch 2 during setup, you can still access its save data on your new device. You have a couple of options here.First, the free option. On your original Switch, go to System Settings > Data Management > Transfer Your Save Data. Click Send Data to Another Console, then pick the user whose saves you want to send to your Switch 2. Pick the saves you want to send over, then click OK. Note that these saves will be deleted from your original console once moved over.Next, with your Switch 2 in close proximity to your Switch 1 (this also needs to be done in person), navigate to System Settings > Data Management > Transfer Your Save Data. Click Receive Save Data. To move data from your Switch 2 to your Switch 1, simply perform these steps in reverse.Second, the paid option. If you have a Nintendo Switch Online membership, you can also use cloud saves to move save data between devices. By default, these are enabled automatically and will keep both of your systems up to date with the most recent saves. However, you can also manually download cloud saves either from a game’s software menu (press + or - while hovering over it on the Switch home screen) or from System Settings > Data Management > Save Data Cloud. You can also disable automatic save data download from here, if you like.Lock your home screen behind a passcodeFinally, you can lock your Switch 2 with a PIN for some added security, kind of like a cell phone. To set this up, simply go to Settings > System > Console Lock. Click OK, then follow the instructions on the screen that pops up to enter your PIN.There’s plenty more to dive into with the Switch 2, which I’ll cover over the following week. For now, though, this should be enough to get you started. Happy gaming!

Taurine supplements have been considered promising for delaying ageing, but that may not be the caseShutterstock / Eugeniusz Dudzinski The amino acid taurine was once thought to decline with age, and animal research suggested that taurine supplements could delay ageing. But a new study shows that the decline doesn’t happen consistently. In fact, taurine levels tend to increase in people over time, suggesting that low levels of the nutrient aren’t a driver of ageing. Previous research has shown that taurine concentrations decline in men as they age and that people with higher taurine levels at 60 years old tend to have better health outcomes. This, along with evidence that taurine supplements extend lifespan in mice and monkeys, suggested that low taurine contributes to ageing.Advertisement The trouble is that taurine fluctuates in response to other factors too, such as illness, stress and diet – therefore, declines in this key amino acid may not be due to ageing. Maria Emilia Fernandez at the National Institute on Aging in Maryland and her colleagues analysed taurine levels in 742 people between 26 and 100 years old. The participants, about half of whom were women, didn’t have underlying health conditions and provided three to five blood samples between January 2006 and October 2018. On average, taurine levels were almost 27 per cent higher in women at 100 years old than at 26 years old and rose about 6 per cent in men between the ages of 30 and 97. Similar results were seen in 32 monkeys that underwent three to seven blood draws between 3 and 32 years of age. Between 5 and 30 years of age, taurine levels rose 72 per cent in female monkeys and 27 per cent in male monkeys, on average. Together, these findings indicate that taurine levels are not a reliable indication of ageing. What’s more, taurine levels also varied widely between people and even within individuals over time, suggesting that other environmental factors influence them, says Fernandez.

Sign up to newsletter However, some people may still benefit from taurine supplementation, says Fernandez, pointing to studies that show it helps regulate blood sugar in people with type 2 diabetes or obesity. But whether it can delay ageing in otherwise healthy people is an open question. Vijay Yadav at Rutgers University in New Jersey says he and his colleagues are currently conducting a clinical trial of taurine supplementation in middle-aged adults. “We hope to finish the trial by the end of 2025,” he says. “Hopefully it will generate sufficiently rigorous data to show whether or not taurine supplementation delays the pace of ageing in humans or increases health and fitness.” Journal reference:Science DOI: 10.1126/science.adl2116 Article amended on 5 June 2025We corrected Vijay Yadav's affiliationTopics:

A significant cyber breach at His Majesty’s Revenue and Customs (HMRC) that saw scammers cheat the public purse out of approximately £47m has been met with dismay from security experts thanks to the sheer simplicity of the attack, which originated via account takeover attempts on legitimate taxpayers. HMRC disclosed the breach to a Treasury Select Committee this week, revealing that hackers accessed the online accounts of about 100,000 people via phishing attacks and managed to claim a significant amount of money in tax rebates before being stopped. It is understood that those individuals affected have been contacted by HMRC – they have not personally lost any money and are not themselves in any trouble. Arrests in the case have already been made. During proceedings, HMRC also came in for criticism by the committee’s chair Meg Hillier, who had learned about the via an earlier news report on the matter, over the length of time taken to come clean over the incident. With phishing emails sent to unwitting taxpayers identified as the initial attack vector for the scammers, HMRC might feel relieved that it has dodged full blame for the incident. But according to Will Richmond-Coggan, a partner specialising in data and cyber disputes at law firm Freeths, even though the tax office had gone to pains to stress its own systems were never actually compromised, the incident underscored just how widespread the consequences of cyber attacks can be – snowballing from simple origins into a multimillion pound loss. “It is clear from HMRC's explanation that the crime against HMRC was only possible because of earlier data breaches and cyber attacks,” said Richmond-Coggan. “Those earlier attacks put personal data in the hands of the criminals which enabled them to impersonate tax payers and apply successfully to claim back tax.” Meanwhile, Gerasim Hovhannisyan, CEO of EasyDMARC, an email security provider, pointed out that phishing against both private individuals and businesses and other organisations had long ago moved beyond the domain of scammers chancing their luck. While this type of scattergun fraud remains a potent threat, particularly to consumers who may not be informed about cyber security matters – the scale of the HMRC phish surely suggests a targeted operation, likely using carefully crafted email purporting to represent HMRC itself, designed to lure self-assessment taxpayers into handing over their accounts. Not only that, but generative artificial intelligence (GenAI) means targeted phishing operations have become exponentially more dangerous in a very short space of time, added Hovhannisyan. “[It] has made [phishing] scalable, polished, and dangerously convincing, often indistinguishable from legitimate communication. And while many organisations have strengthened their security perimeters, email remains the most consistently exploited and underestimated attack vector,” he said. “These scams exploit human trust, using urgency, authority, and increasingly realistic impersonation tactics. If HMRC can be phished, anyone can.” Added Hovhannisyan: “What’s more alarming is that the Treasury Select Committee only learned of the breach through the news. When £47m is stolen through impersonation, institutions can’t afford to stay quiet. Delayed disclosure erodes trust, stalls response, and gives attackers room to manoeuvre.” Once again a service’s end-users have turned out to be the source of a cyber attack and as such, whether they are internal or – as in this case – external, are often considered an organisation’s first line of defence. However, it is not always wise to take this approach, and for an organisation like HMRC daily engaging with members of the public, it is also not really possible. Security education is a difficult proposition at the best of times and although the UK’s National Cyber Security Centre (NCSC) provides extensive advice and guidance on spotting and dealing with phishing emails for consumers – it also operates a phishing reporting service that as of April 2025 has received over 41 million scam reports – bodies like HMRC cannot rely on everybody having visited the NCSC’s website. As such, Mike Britton, chief information officer (CIO) at Abnormal AI, a specialist in phishing, social engineering and account takeover prevention, argued that HMRC could and should have done more from a technical perspective. “Governments will always be a high tier target for cyber criminals due to the valuable information they hold. In fact, attacks against this sector are rising,” he said. “In this case, it looks like criminals utilised account take over to conduct fraud. To combat this, multifactor authentication (MFA) is key, but as attacks grow more sophisticated, further steps must be taken.” Britton said organisations like HMRC really needed to consider adopting more layered security strategies, not only including MFA but also incorporating wider visibility and unified controls across its IT systems. Account takeover attacks such as the ones seen in this incident can unfold quickly, he added, so its cyber function should also be equipped with the tools to identify and remediate compromised accounts on the fly.

A healthy dose of judicious skepticism is crucial to preventing phishing attacks, said David Fine, supervisory special agent at the FBI, during a presentation at a HIMSS event. Exchange admins got a boost from Microsoft when it improved how it handles DMARC authentication failures to help organisations fight back from email-based attacks on their users.
