If you’re a longtime Apple user, you know the mix of anticipation and dread that accompanies any interface update. Oftentimes, the frustration of waking up to find your iPhone updated to the latest operating system is enough to turn any tech-savvy customer into a begrudging Luddite. iOS 26, for instance, was particularly contentious. Introducing the company’s Liquid Glass redesign and a barrage of Apple Intelligence AI features, iOS 26 was the most dramatic shift in the company’s operating system design since iOS 7. And while some hailed the system as ushering in the next era of Apple products, others were less impressed. Complaints ranged from finicky performance to battery-hungry.

Part of this redesign meant a series of shifts, changing both the aesthetics and capabilities of several customer favorites. One such revamp involved Apple’s beloved Wallet application, which is beefed up with several helpful features to complement its new look. Apple’s boarding pass system saw several changes, adding a host of new features. However, not every boarding pass is included in the update, as the Apple allowed individual airlines to decide whether to support the new application. To date, four North American airlines have rolled out revamped boarding passes, including Air Canada, American Airlines, Southwest Airlines, and United Airlines.

Reportedly, several airlines are sure to follow, like JetBlue, Jetstar, Lufthansa, Qantas, and Virgin Australia. Meanwhile, Delta introduced the new features before withdrawing its updated application due to software glitches. However, Delta is expected to return to the new Wallet format soon. Overall, it is a rare software update to a fan favorite application that might actually be more helpful than frustrating.

A new digital boarding pass experience

The first thing users are likely to see when opening a new boarding pass is its revamped look. Like other Liquid Glass applications that received a new design, Apple’s new Wallet provides a more aesthetic experience that Apple claims is “more dynamic and configurable than ever before.” One area of improvement is boarding pass’s integration of popular Apple applications. For example, Wallet allows users to track luggage via the FindMy app. The application has integrated with Apple Maps, allowing users to navigate to, and within, airport terminals. An airline services and updates section at the bottom of the boarding pass enables travelers to customize flight experiences. In this window, users can adjust flight details, change seats, add baggage, or upgrade to priority boarding directly in the Wallet application.

A major capabilities shift is in the system’s live updates. Integrating with Apple’s flight services, the new boarding passes automatically update whenever a flight changes gates or experiences a delay, keeping an itinerary up to date. A new live activity feature shows users’ flight information throughout a trip. Users can then share this information via Messages, allowing loved ones to track the progress of their flight. With this feature, users who add an updated boarding pass subscribe to the flight’s updated flight status. Updates are automatically showcased on both the pass itself and the live activity feature. No more pestering your family members about arrival times when a flight gets delayed or trying to calculate how much time you have to clean the house before your a friend arrives for a cross-country vacation.

Additional changes to Wallet

In addition to its boarding pass update, Apple has delivered several changes to Wallet that enhance the user experience. For travelers, updates like Digital ID allow travelers to create an identification card via their U.S. passport. Users can present this ID at TSA checkpoints and other accepting locations. Similarly, wallet has made it easier to securely verify user’s identities when using web applications. According to Apple’s developer page, “instead of requiring people to scan documents or take selfies, websites can reduce friction and abandonment by letting people complete verification with a user-friendly and simple experience.” Such functionalities extend to the business side as well, as its ID Verifier functionalities allow organizations to securely verify a customer’s identity without burdensome hardware.

Along the same lines as the boarding pass update, Apple has added several features to its ticketing practices. For instance, Wallet can now hold multiple events in a single ticket. This means that season ticket holders can easily manage a sequence, as each game or event ticket retains a “comprehensive event guide, seating information, and unique ticket management link” despite sitting in the same location in your Wallet. Apple also made it easier for developers to integrate tickets into Wallet’s API, expanding functionalities to everything from loyalty cards to car rental passes.

As with Apple’s integration of FindMy and Maps into its boarding pass experience, it’s also expanding the functionalities of its Wallet application. For instance, Wallet’s integration of Mail will allow consumers to track packages and orders. Using Apple Intelligence, Wallet can display key information about your order, including merchant names, tracking numbers, and shipping status. FinanceKit, meanwhile, allows financial management applications using Apple Wallet to share information.

It’s always fun to buy some new accessories for your PC setup, though buying every single accessory that catches your eye will probably rack up a rather unpleasant bill. 3D printing can yield all sorts of useful tools and gadgets, though even some 3D prints can have hidden costs, whether it’s an internal Raspberry Pi or even just a set of screws. If you’re feeling particularly thrifty, you can still source all manner of accessories, from keycap pullers to headphone stands, for no more than the cost of the filament you use, and very little filament at that.

Owning a 3D printer allows you to craft bespoke solutions to life’s many little headaches. Rather than having to source an external solution from a store or online for whatever’s annoying you about your computer setup, you can create something simple, streamlined, and cost-effective to perfectly suit your needs. If you need some ideas for minimalistic projects, you can find them on 3D printing enthusiast websites like Printables.

Keycap puller supreme

If you own a mechanical keyboard with hot-swappable keys, you can remove those keys for both repair and customization purposes, such as adding decorative keycaps over keys you don’t normally use. However, if you want to do this, you can’t just yank off keys with your fingers. You need a dedicated keycap puller tool, which you can create using a 3D printer.

Printables user Braga3Dprint wanted a simple and effective tool for removing keys from any mechanical keyboard, so they designed the Keycap Puller Supreme. Despite the fancy name, it’s a very simple, user-friendly tool, designed to be used without damaging your keycaps. Just insert the tabs into the notches between keys, give it a squeeze, and the cap should pop right off.

The project includes two variations of the keycap puller: a short one and a longer one, to accommodate different sizes of mechanical keyboards and keycaps. As an added perk, the puller’s basic ring-like shape uses very little filament, so it’d almost definitely be cheaper to make than to buy a similar tool.

Modern monitor stand

While most computer monitors come with some sort of stand, it’s a bit of a toss-up whether that stand will actually raise the display to eye level. Sometimes, you need to add a little extra elevation beneath your monitor, and if you’re going to do that, why not do it with a little modern style by 3D printing the Modern Monitor Stand?

Printables user 8042 designed a small desktop monitor stand based on the Sotheby’s Furtif Desk, copying its stylish, modern design in a compact package. Despite its unusual shape, it’s strong enough to keep a monitor safely propped up, with the flat panels easy to scale up if you need something a little larger. 8042 printed the stand with a 5% gyroid infill to give it sufficient strength to lift their approximately 5kg monitor (approx. 11 lbs), though they suggest using a higher infill percentage with a more complex pattern to make it thicker if you have a larger, heavier monitor. Another Printables user in the comments noted that, since this design is so easy to print, they made two and used them to prop up their laptop.

Ergonomic mouse wrist rest

Working a desk job and constantly moving your mouse can be absolute murder on your wrist over the long term, which is why ergonomics are so important when shopping for PC accessories. Unfortunately, ergonomics is not an all-encompassing science; what fits one hand perfectly might not be as comfortable for another. Rather than buying a bunch of wrist rests at random, try making one with your 3D printer and customizing it to your preferences.

Printables user Referentiel wanted a simple way to avoid wrist pain while working at a computer all day, so they created an equally simple solution: an ergonomic mouse wrist rest. It’s exactly what it sounds like: a no-frills stand to place behind your mouse on your desk, where you can rest your wrist while working. Just having a smooth, ergonomic surface where you can rest your hand is already helpful, but since this project has a very simple design, it’s also very easy to customize. Users in the comments have added various simple modifications, such as adding gripping pads to the bottom, which you can find at your local hardware store for around $3.

Cable tag set

The more complicated your PC setup gets, the more assorted cables you’re going to have snaking around behind your desk. While a cable organizer can help keep them from getting tangled, it can still be difficult to discern which cables are connected to what at a glance. You could try wrapping colored ties around them, but instead of having to invent a color-coding system for yourself, just 3D print some cable tags with simple pictures on them.

Printables user Alego designed a set of 29 assorted cable tags, each consisting of a small illustration attached to a hook sized for cables ranging from 3 to 9 mm in diameter. These tags can denote just about any cable you could possibly find behind a computer desk or entertainment center, including, but not limited to, power cables, Ethernet cables, Raspberry Pi cables, monitor cables, and, of course, 3D printer cables. Alego cautions that, due to the cables’ small size and flat design, they can be a little tricky to remove from your 3D printer’s bed. They recommend printing them on a smooth steel sheet, then carefully working the tags and hooks off using a spatula. Using the right surface is a great way to improve your 3D printer’s print quality.

Minimalist desk headphone stand

Minimalism is the way of the future for many, with both home decor and gadgets for minimalists becoming popular purchases. It makes sense; opting for minimalist designs is a great way to reduce clutter in your living and work spaces. One particular spot that could probably do with a decluttering is your desk, especially if you usually leave your work or gaming headset lying on it. Free up some space by 3D printing a minimalist headphone stand.

Printables user xxoticlucas was tired of their loose headphones cluttering their desk, so they designed a straightforward, sturdy mounting point to keep them propped up and free up some space. This headphone stand has no frills, bells, or whistles; it’s a thick pole with a solid, flat bottom and a curved hook on top that keeps your headphones anchored to your desk while taking up a fraction of the space. It requires no additional components or much filament, making it the perfect budget option for sprucing up your computer space.

The United States has a road fatality problem. Heightened safety regulations, anti-impaired driving laws, and road design improvements have forced traffic-related deaths to decline, cutting deaths per capita in half since 1972. However, vehicular deaths have also increased by over 10% between 2019 and 2023. 12,000 of these deaths, almost 30%, were related to excessive speeds. And while some lawmakers are adding automated cameras to address speeding, others have opted for a more direct approach.

One increasingly popular fix is mandating speed limiters for drivers convicted of reckless driving. Speed assistant devices limit a car’s maximum speed to prevent it from reaching dangerous levels. A new strain of smart speed limiters, dubbed intelligent speed assistance (ISA) devices, utilizes GPS tracking to adjust caps based on posted speed limits. The technology has proven to be a powerful tool in Europe, where the European Commission’s Vehicle General Safety Regulations mandate ISAs be installed in all new European vehicles since 2024.

American lawmakers are pushing to utilize these technologies to halt reckless drivers in their tracks. To date, Virginia, Washington, and Washington, D.C. have begun rolling out ISA pilot programs, while at least 10 other states are considering speed limiter legislation. For the most part, American regulators favor targeted enforcement, focusing on drivers with dangerous histories. Federal lawmakers continue to grapple over whether to deploy speed limiters in the commercial trucking sector. 

Speed limiters: an overview

Intelligent speed assistance devices prevent drivers from reaching dangerously excessive speeds. They also collate data from a variety of sources to accurately determine the speed limit. Typically, ISAs utilize GPS, camera-based traffic sign recognition software, and digitally mapped speed limits to determine the appropriate driving speed. Speed limiters filter said information through the engine’s computer system, which regulates the fuel and air used to accelerate. Some systems allow drivers to toggle these functions. 

ISA devices take several approaches to preventing reckless driving. The least invasive are dubbed ‘open systems,’ in which ISAs provide visual or auditory signals to alert drivers when they exceed the speed limit. Such a warning can take place via dashboard lights, loud beeps, or even pedal vibrations. A second approach, similar to cruise control, is a ‘half open system,’ in which an ISA adds physical resistance to the accelerator to prevent excessive speeding. Mandatory speed compliance systems prevent drivers from exceeding driving limits by physically curtailing the car’s maximum speed. Critically, ISAs do not engage a vehicle’s brake system. These systems provide significant advantages to speed governors, as they allow speed restrictions to adjust depending on a driver’s location. 

According to the National Highway Traffic Safety Administration, studies have shown ISAs to be an effective means of reducing speeding, and “suggest widespread or universal deployment of ISA could lead to significant crash, fatality, and injury reductions.” Meanwhile, the European Transport Safety Council expects the EU’s ISA regulations to reduce road deaths by 20%. 

The U.S. speed limiter landscape

Washington, D.C., implemented the country’s first ISA law in October 2025. Following DC’s successful Ignition Interlock Device Program, which mandates that drivers with DUI convictions install an ignition interlock device, the pilot program requires drivers convicted of aggravated reckless driving to install an ISA. Both Washington and Virginia enacted similar ISA regulations. In both cases, ISA enrollment serves as an alternative to suspending a driver’s license following severe driving convictions. Maryland, meanwhile, passed its Stop Super Speeders bill in April 2026. The law now awaits Governor Wes Moore’s signature.

As it stands, several states are considering ISA programs to slow down super speeders, including Arizona, New York, Vermont, Wisconsin, Pennsylvania, New Hampshire, Hawaii, Connecticut, and Illinois. California, meanwhile, attempted to follow Europe’s lead and mandate that ISAs be installed in every new vehicle, but Governor Gavin Newsom vetoed the law in 2024. Now, the state’s assembly will consider the Stop Super Speeders Act, a more targeted ISA program similar to those implemented in Virginia and Washington. Meanwhile, Georgia Governor Brian Kemp vetoed his state’s speed limiter law in 2025.

Not every lawmaker is enthusiastic about speed limiters. The Trump administration’s Department of Transportation, for instance, nixed potential mandates requiring trucks with a gross weight over 26,001 pounds to install speed limiters. The controversial proposal, an Obama-era suggestion reupped by the Biden administration, saw safety and trucking advocates tussle over the merits of mandating speed limiters in the commercial sector. Republican lawmakers doubled down on this decision by proposing the DRIVE Act to bar federal agencies from imposing speed-limiter regulations. Interestingly, the DOT included intelligent speed assist strategies in its April 2026 Pathways to Safer Streets” initiative announcement. In either sense, if state-level regulations are any indicator, the technology is likely here to stay.

Scientists say they may be able to design DNA without copying it, opening the door for major advancements in biology and biotech. Specific enzymes can sometimes create DNA that strays from a given template — a process called untemplated DNA synthesis or doodling. Scientists have treated doodling as little more than a curiosity since its discovery in the 1960s, but now researchers at the University of Bristol believe they may be able to influence doodling to help design DNA, as reported in a study published in Nature Communications. For decades, scientists relied on enzymes called polymerases to build DNA one nucleotide at a time, following an existing template. However, the study suggests they may not need a template, and doodling can produce DNA strands up to 85,364 nucleotides long. Chemically synthesized strands typically max out at 200 nucleotides, though a recent record from another study topped 1,700 nucleotides.

Scientists have only tested the process in labs, using specific enzymes and carefully tuned conditions to guide doodles. Translating the results into living cells is a different challenge, though. Polymerases will face a living system that wants to eliminate doodles. During the DNA replication process, polymerases check their own work as they go. Mismatched or doodled DNA will be removed almost immediately. Certain proteins also keep DNA creation clamped to a template, making it more difficult to doodle. And there are cell-cycle checkpoints, where a cell can pause the process if replication looks abnormal. Despite the difficulties ahead, the implications of this study could have an incredible impact on our lives.

How doodled DNA could transform medicine

DNA design often relies on trial and error. Scientists work from existing sequences, modifying them and testing what works. The discovery suggests scientists may not have to start with existing DNA to create something new. To be clear, the breakthrough doesn’t mean doctors will be able to erase your family’s history of colon cancer. And don’t expect scientists to doodle new organs, even as other research explores 3D printing inside your body. This discovery is more about moving research forward.

Drug development currently requires a lot of luck. Researchers test thousands of compounds to see what works. If they can control doodling, it could allow them to design DNA sequences more predictably. In theory, that would mean building biological therapies faster, including utilizing gene-editing systems like CRISPR (which another study says might be able to treat cancer), as well as antibodies that can detect and block viruses, dangerous bacteria, and cancer cells. Instead of mass-producing treatments, designed DNA could establish therapies to match your genetic profile, such as drugs that fit your metabolism and immune response, and dosing with fewer side effects.

The biggest advancement could happen outside of your body, though. The study suggests the background noise doodling creates could be filtered out, eliminating false positives in testing. It would make early cancer screenings and infection tests more reliable, potentially stopping diseases before they cause damage. Scientists still have years of research before controlled doodling reaches everyday applications, but the breakthrough pushes DNA research into new territory, much like recent breakthroughs in the creation of artificial DNA.

If your PC is chugging along and trying its best to load programs and play games, but it struggles to boot up, you don’t have to buy a new one. There are several upgrades you can make to an outdated computer that can improve its performance, making it like new once again. That’s one of the greatest features of a desktop: They’re customizable, so all you may need to do is replace one part to have your older model operating more smoothly.

There are many components you could replace to beef up your PC. Even with AI leading to rising prices of RAM and storage like DDR4 RAM, there are options to make sure your PC operates at its best potential without spending thousands on parts. One essential piece of technology you may want to look into first when deciding to upgrade is a solid-state drive (SSD) or hard disk drive (HDD).

Solid-state drives are the norm for more modern PCs built in recent years, but older models are more prone to feature spinning hard disk drives. Upgrading either the SSD or HDD for your PC is a great first option if you’re looking to expand the capabilities, speed, and latency of your PC. Both drive types serve a similar purpose when it comes to storing data, games, and files, but they operate rather differently when it comes to load times and booting up the system and applications.

The differences and similarities between SSD and HDD

Upgrading the SSD or HDD of a dying PC is a great way to ensure it continues to operate at or near peak efficiency. You’re free to decide between them as both serve the same purpose of expanding storage for your PC. However, there are key components to take note of when choosing which drive works best for you. One operates more quickly than the other, but all that speed comes at a cost.

Knowing how you intend to use your PC will help you decide on a drive. If you just need to save documents or shuttle some pictures off to long-term storage, you may not need an expensive SSD since HDDs work best for containing data at a much lower price tag. However, they tend to be slower than SSDs and may work best as an additional drive to your previously installed one, mainly for backup or overflow storage. If you’re after enhanced performance, an SSD provides quicker boot times, enhanced program launch speed, and faster file transfers. Yet all of that does come with a steeper price point, but there are cheap, reliable SSD brands available. Both drive types are available as external or internal upgrades and, in many cases, if your PC feels outdated or is struggling to perform, upgrading its storage can make it more reliable.

What to replace after SSD and HDD

Drives are just the tip of the iceberg when it comes to upgrading an outdated PC. They are a great starting point, though, and once you’re through adding your drive of choice, you can move on to additional upgrades. You really should replace these popular GPUs in 2026, then pick up some RAM, once your SSD or HDD is installed. Adding new parts can save you money and time in the long run when compared to outright purchasing a brand-new PC.

If your PC is running out of memory and you want to improve the performance of your applications and overall system, adding more RAM is vital. While SSD and HDD can be added to just about any PC — desktops and even laptops — RAM is a more specialized component. You’ll need to make sure it is compatible with your computer before purchasing so it will function properly. Often, RAM slots into your PC easily, and you can add multiple memory cards for additional capacity, but adding RAM to your laptop can be a bit complicated.

For those who have older PCs that may seem to be getting slower as time passes by, you don’t have to be stuck with a dinosaur or spend your hard-earned cash on a new machine. If you’re looking to breathe new life into your dying computer, replacing parts is one of the best things you can do, starting by adding an upgraded SSD or HDD.

Whenever you visit a website for the first time, your browser downloads the data needed to display it. If the website has a lot of graphic elements, this can take a while, which is why websites load slower the first time you open them (especially if you have a slow Wi-Fi connection). Downloading the same data each time you visit the same website isn’t efficient, and waiting for the same images to load while your browser redownloads them isn’t ideal either. Fortunately, your browser is quite smart and uses cached data to deal with this.

While certainly a useful feature, there are many reasons you might want to clear your browser cache. For example, if Chrome is suddenly slow or a website isn’t loading, one of the most common troubleshooting methods is clearing the browser’s cache. Fortunately, Google makes doing so very straightforward. On a PC or laptop, click on the three vertically aligned dots on the top-right corner of your browser window, then go to Settings and open the Privacy and security submenu on the left before clicking on Delete browsing data.

This will open a prompt where you can choose what to delete (cached images, browser history, or cookies) and also what time period you want to clear the selected options for (the last hour, the last month, or all time). You can follow the same steps to clear Google Chrome cache on a Mac, but you also get a Delete browsing data shortcut right when you click the three dots in the top-right corner.

How to clear Google Chrome cache on your phone

Deleting Google Chrome cache on your phone is similar to how the process works on Windows or Mac. On Android, tap the three vertical dots in the top-right corner of your screen, then scroll down and open Settings. Here, tap on Privacy and security and then Delete browsing data.

On iOS, you’ll find the three dots in the bottom-right corner instead. Tap these and select Settings from the menu that appears. Just like with Android, scroll down and tap Privacy and security and then select Delete browsing data. Just like on a computer, you can select the type of data to be deleted and how far back you want the deletion to go, regardless of whether the phone’s running Android or iOS.

Alternatively, if you just want to quickly delete the cached images and other storage-hoarding files and don’t care about targeting specific areas, you can delete your browser cache from your phone’s settings, but this only works on Android. To do this, open the Settings app on your phone and select Apps, then choose Google Chrome from the list — if you don’t see it, you may have to tap See all apps first. Next, tap on Storage or Storage & cache. You can then select Clear cache to get rid of excess temporary files, or tap on Clear user data to get rid of cache while resetting the browser.

When to clear your Google Chrome cache

There’s not a straightforward answer as to when you should clear your Google Chrome cache. Generally, you only need to clear your browser cache when you’re facing an issue that might be caused by this cache. This can be a laggy or slow browser, specific sites refusing to load, or an issue with images and videos being displayed. You might also want to clear your browser cache if a website loads properly, but always defaults back to a specific anchor each time you do so — such as your Slack or Discord showing old messages each time you reload the website.

If you’re not facing any issue, then it’s completely fine to not worry about clearing your browser cache. It’s still a good idea to do cleanups every month or so, because older cache can become corrupted with time, leading to slower load times. This cache can also pile up and lead to storage issues, especially if you’re on a phone with limited storage space and often visit sites that display lots of images or play large videos.

If there’s a particular genre of serialized television that seems to have remarkable pop-culture staying power, it’s sci-fi, from the many iterations of “Star Trek” to the cult-classic “Firefly.” Amongst these beloved shows, a name that frequently pops up from the mid-90s is “Sliders,” a sci-fi series that ran from 1995 to 2000, following the exploits of a young genius, played by Jerry O’Connell, who “slides” between parallel Earths and attempts to return home. Next to his childhood role in Rob Reiner’s “Stand By Me,” it’s one of O’Connell’s most notable performances.

“Sliders” ran for five seasons in total: the first three on Fox and the last two on the Sci-Fi Channel. The show was a fan-favorite in its time thanks to its novel premise and some clever social commentary, though behind the scenes, there were routine disagreements between the actors, the writers, and the network that created an overall rocky production. There are a number of factors that one could attribute the show’s ultimate cancellation to, but at the very least, it does still maintain cult-classic status in the sci-fi community.

Sliders followed a group jumping through various parallel realities

The initial premise of “Sliders” focused on Jerry O’Connell’s character, Quinn Mallory, a genius physics student whose experiments inadvertently open a wormhole through the fabric of space and time, through which is a parallel version of Earth. Quinn enters the hole alongside his companions, Professor Arturo (John Rhys-Davies), Wade (Sabrina Lloyd), and Rembrandt (Cleavant Derricks), using a device that allows them to return home after a set period. However, when the group uses the device earlier than anticipated, it loses the coordinates for their home dimension, sending them to a completely different Earth. Stranded and with no clear path home, they have no choice but to keep sliding in the hope that they will make it back to their Earth.

Each episode of the show focused on a different parallel Earth with a unique setting and history. Some episodes would have radically different histories, such as the pilot episode, in which the United States is ruled by the Soviet Union, while others would present ostensibly normal Earths with unusual circumstances, such as one about to be impacted by a catastrophic asteroid. This allowed the show to present some interesting social commentary and conundrums, which was a major element that endeared it to fans. It was certainly a more nuanced take on a multiverse than what we see these days from the MCU.

While the strong premise of “Sliders” helped it find its fans, the behind-the-scenes production was notoriously contentious. Part of the initial problem was that the first few episodes of the first season on Fox aired out of order, despite the show being serialized, which confused viewers. The corporate meddling would continue in the third season, which saw a major shift from thought-provoking stories to mindless action. It was this particular shift that John Rhys-Davies found objectionable, leaving the show midway through the third season due to conflicts with the writing staff, and costing it one of its most beloved characters, Professor Arturo.

Fox ultimately canceled the show after the third season, but it was picked up by the Sci-Fi Channel, which ordered two more seasons. Unfortunately, Sabrina Lloyd wasn’t interested in continuing, so the show dropped Wade, and at the end of season four, even its protagonist, Jerry O’Connell, was out. For the fifth season, O’Connell was replaced by Robert Floyd, with a hand-waving explanation for why the character of Quinn Mallory suddenly looked different. Despite the season ending on a cliffhanger, the Sci-Fi Channel canceled “Sliders,” leaving the story unresolved over 20 years later.

Despite everything, both Jerry O’Connell and John Rhys-Davies have expressed fondness for the show at its peak, with Rhys-Davies even floating the idea of a modern revival in the spirit of the early seasons. For the time being, the show is available to stream on Peacock, where newer fans can appreciate it for what it was.

Since Amazon unveiled the Kindle Colorsoft, the ereader has seen quite a bit of hype. Not only do some argue it’s the first Kindle they want to buy, but the device finally makes it easier to enjoy the colorful illustrations of books and covers that you previously had to read on a tablet or physical edition to make the most of. However, there’s one big feature that has been missing from the Colorsoft since its launch a couple of years ago: dark mode. Thankfully, Colorsoft owners will soon be able to take full advantage of the more night-reading-friendly theme, and some are already seeing it on their devices.

The new feature is currently being pushed out to both Kindle Colorsoft and Kindle Scribe Colorsoft, reports note, and once it arrives on your Kindle, you should be able to enable it from the quick settings panel (accessed by swiping down from the top of the screen). Once enabled, it will affect your home screen, reading screen, and even your library, though you should be able to customize it so that it does not affect your notebooks on the Scribe Colorsoft.

A meaningful update

While dark mode might seem like a small feature, it’s almost a must-have for night-time readers, especially if you prefer to read in darker environments. While it is believed to be easier on the eyes, the jury is still out on exactly how scientifically backed the assumption that it’s better for your eyes is. Still, there’s no arguing that dark mode has become a bit of a staple on devices these days, and while the Kindle’s starker white light mode can be genuinely useful in bright environments, it can feel almost blinding in dimmer rooms.

Unfortunately, Amazon hasn’t shared an exact rollout timetable for the update that brings dark mode to the Kindle Colorsoft and Scribe Colorsoft. You can check out the latest update details for all Kindles on Amazon’s website, where the company will post the full patch notes once they are live. As for when it will roll out, reports suggest it should arrive on devices within the next few weeks, and that it has already appeared on some Colorsoft devices within the last week or two.

While dark mode has taken a bit to get to the Kindle Colorsoft, the arrival just means one less reason to read on your smartphone, and it could make upgrading to the Colorsoft now that Amazon is killing support for some older Kindles even more appealing.

While the Artemis II mission captured the public’s imagination and revitalized interest in space exploration, it’s only the first step. The ultimate goal of the Artemis program is to establish a permanent footprint on the moon by way of a base on the lunar South Pole. However, any such colony will require sustained nuclear power to drive vital systems like life support. Despite slashing the agency’s budget, the White House has tasked NASA with providing said lunar nuclear development.

Nuclear power is the only viable solution to power a moon base because of the challenges presented by other fuel sources. Continuously transporting traditional fossil fuels from Earth is unfeasible due to the logistics and expense of such a project, and because the lunar surface alternates between two weeks of sunlight and two weeks of night, solar is out as well. There’s also no wind nor flowing water on the moon’s surface to drive turbines, leaving nuclear as the only realistic option.

The White House has instructed agencies to begin prototyping nuclear reactors that can be deployed to the lunar orbit as soon as 2028, with surface reactors following by 2030. Here’s how Washington envisions the timeline, giving us a better idea of NASA’s future of space exploration including an eventual mission to Mars.

The blueprint for lunar nuclear power by 2030

To achieve its goal of deploying nuclear power to the moon for an eventual lunar base, the White House has created a program dubbed the National Initiative for American Space Nuclear Power. As part of the initiative, the White House has instructed NASA to begin prototyping nuclear reactors with the goal of developing a mid-power reactor suitable for the moon’s surface by 2030. In the memorandum laying out the mission, NASA defines a mid-power reactor as capable of generating at least 20 kWe (kilowatts electrical) — enough power to run about 10–15 average U.S. homes at once — “during at least 3 years in orbit and at least 5 years on the lunar surface.”

As a stepping stone, the memo recommends that NASA consider developing low-power (1 kWe) reactors that can share components or development insights with higher-powered reactors. The ultimate goal of the program is to supply more potent generators, capable of outputting 100 kWe or more, enough power for 60-90 average U.S. homes. Low- to mid-power reactors should all be built, according to the memo, with extensibility to a higher output level in mind.

NASA’s long term nuclear ambitions

The initiative was revealed in an executive order issued on December 18, 2025, and it was formalized at an event in April by Office of Science and Technology Policy (OSTP) Director Michael Kratsios and NASA Administrator Jared Isaacman. An early goal is to create nuclear electric propulsion (NEP) systems alongside the reactors, which will pair with “launch vehicles that are or will be readily available by 2029”. Part of the NEP side of the program is repurposing the Power and Propulsion Element that was originally developed for the Gateway (a scrapped space station meant to orbit the moon) by 2028.

It will become the Space Reactor 1 Freedom (SR-1), an NEP system featuring a 20-kWe fission reactor at one end that will power ion thrusters at the other. The SR-1 will deposit three robot helicopters on Mars before continuing its journey further into the solar system. The Ingenuity-class helicopters will scout the Marian surface for potential landing sites for future human missions as part of a project called Skyfall.

NASA has released a “user’s guide” that lays out three phases of research, development, and deployment all building to an operational moon base. According to the guide, a moon colony will allow researchers to “develop, test, and demonstrate needed technologies, capabilities, systems, and operational paradigms for future human missions to Mars” and “provide experts with data needed to understand the impacts of long-duration spaceflight missions on human explorers.”
