Scientists Just Doubled Our Catalog of Black Hole and Neutron Star Collisions

Published

on

Colliding black holes were detected through spacetime ripples for the first time in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO), notes Space.com:


Since then, LIGO and its partner gravitational wave detectors Virgo in Italy and KAGRA (Kamioka Gravitational Wave Detector) in Japan have detected a multitude of gravitational waves from colliding black holes, merging neutron stars, and even the odd “mixed merger” between a black hole and a neutron star… During the first three observing runs of LIGO, Virgo and KAGRA, scientists had only “heard” 90 potential gravitational wave sources.

But now they’ve published new data from the LIGO-Virgo-KAGRA (LVK) Collaboration that includes 128 more gravitatational wave sources — some incredibly distant:

[Gravitational-Wave Transient Catalog-4.0, or GWTC-4] was collected during the fourth observational run of these gravitational wave detectors, which was conducted between May 2023 and Jan. 2024… Excitingly, GWTC-4 could technically have been even larger, as around 170 other gravitational wave detections made by LIGO, Virgo and KAGRA haven’t yet made their way into the catalog.

One aspect of GWTC-4 that really stands out is the variety of events that created these signals. Within this catalog are gravitational waves from mergers between the heaviest black hole binaries yet, each about 130 times as massive as the sun, lopsided mergers between black holes with seriously mismatched masses, and black holes that are spinning at incredible speeds of around 40% the speed of light. In these cases, scientists think the extreme characteristics of the black holes involved in these mergers are the result of prior collisions, providing evidence of merger chains that explain how some black holes grow to masses billions of times that of the sun… GWTC-4 also includes two new mixed mergers involving black holes and neutron stars.

[LVK member Daniel Williams, of the University of Glasgow in the U.K., said in their statement] “We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically interesting and unusual.” The catalog also demonstrates just how sensitive the LVK detectors have become. Some of the neutron star mergers occurred up to 1 billion light-years away, while some of the black hole mergers occurred up to 10 billion light-years away.
Einstein’s theory of general relativity can be tested with these detections, and “So far, the theory is passing all our tests,” says LVK member Aaron Zimmerman, of the University of Texas at Austin. “But we’re also learning that we have to make even more accurate predictions to keep up with all the data the universe is giving us.” And LVK member Rachel Gray, a lecturer at the University of Glasgow, says “every merging black hole gives us a measurement of the Hubble constant, and by combining all of the gravitational wave sources together, we can vastly improve how accurate this measurement is.”

In short, says LVK member Lucy Thomas of the California Institute of Technology (Caltech), “Each new gravitational-wave detection allows us to unlock another piece of the universe’s puzzle in ways we couldn’t just a decade ago.”

Schiit Asgard X Headphone Amp Packs Mjolnir Tech and Continuity A Power for Under $550 at CanJam NYC 2026

Published

on

At CanJam NYC 2026, Schiit Audio kept a lower profile than in past years, but the Texas based manufacturer still had something worth hearing. The company has now fully relocated operations from California to facilities in San Antonio and Corpus Christi, and judging by what we heard at the show, the move hasn’t slowed development one bit.

Front and center was the Schiit Asgard X headphone amplifier, a modular desktop amp that pulls technology directly from Schiit’s flagship Schiit Mjolnir headphone amplifier. The new model introduces Schiit’s Continuity A output stage and supports an optional internal DAC card that adds digital control through the company’s Schiit Forkbeard control system. The demo unit on the table included the DAC module and was paired with the Grado HP100 SE headphones we reviewed in 2025, making it one of the more interesting desktop headphone rigs on the show floor.

The result is a mid tier amplifier that looks familiar on the outside but carries more serious tech under the hood. With trickle down circuitry from the Mjolnir platform, app based control, and modular expandability, the Asgard X feels less like a routine update and more like Schiit raiding its own vault for parts. And judging by the crowd around the table, New York City still appreciates a little well engineered Schiit.

Schiit Audio Asgard X Class A Headphone Amp/DAC Silver Angle

Asgard X: Class A Power and a Little More Useful Schiit

Base price starts at $399, which gets you the amplifier and preamp functionality. Add the Mesh DAC card for $150, and the Asgard X turns into a compact all in one desktop rig with digital input and app control through Schiit’s Forkbeard control system. That’s where things get more interesting.

The DAC card introduces Schiit’s Mesh digital architecture, a custom filter design that is optimized in both the time and frequency domains rather than chasing the usual marketing buzzwords. The bigger change for day to day use is Forkbeard. Through the app you can control volume, balance, loudness, phase, NOS mode, and even adjust a full three band parametric EQ. In other words, the kind of controls people usually beg for once they realize their desktop stack requires three remotes and a flashlight.

Power output is more than adequate for most headphones:

  • 3.4W RMS at 16 ohms
  • 2.8W RMS at 32 ohms
  • 1.9W RMS at 50 ohms
  • 380mW RMS at 300 ohms
  • 200mW RMS at 600 ohms

Digital input is handled through Schiit’s Unison USB interface, supporting sample rates up to 384 kHz. No DSD. No MQA. We can hear Jason and Mike laughing all the way from Times Square.

No smoke machines, no Thor cosplay. Just a modular desktop amp with plenty of power, a DAC option that actually adds functionality, and enough control to keep both the Brooklyn headphone crowd and the Texas engineers reasonably happy.

Listening to the Asgard X: Class A Power, No Funny Schiit

Right off the bat, it was clear the Schiit Asgard X headphone amplifier had more than enough power and headroom to keep the Grado HP100 SE headphones fully under control. It didn’t try to goose the top end with extra sparkle, but where it really impressed was from the bass through the lower midrange. Black Sabbath and AC/DC had real weight and drive, while Deadmau5 and Kraftwerk showed just how well the amp handles pacing and rhythmic energy.

The treble could use a bit more air on some recordings, but the sense of space and impact made up for it. Percussion had real snap, kick drums landed with authority, and the overall timing kept everything moving forward with purpose. It’s the kind of presentation that makes you stop analyzing after a few tracks and just keep listening.

The Grado HP100 SE headphones have always handled vocals well, and that remained true here, though I did find myself wishing for a little more illumination at the top. Some higher notes came across slightly muted on certain tracks, but I’ll take that over a presentation that turns hard or brittle after a few minutes. Your mileage may vary depending on the recording, but in this setup the balance leaned toward smooth and listenable rather than aggressively detailed.

The Bottom Line

The Schiit Asgard X headphone amplifier is aimed squarely at listeners who want a powerful Class A desktop amp without turning their desk into a stack of separate components. At $399, it works well as a straightforward headphone amp and preamp, and the optional Mesh DAC card adds modern convenience through Schiit Forkbeard control system without complicating the design.

With solid power, modular flexibility, and a sound that favors weight, pacing, and long listening sessions over flashy treble, the Asgard X makes the most sense for desktop headphone listeners who value control and usability over chasing the last ounce of analytical detail.

Fascinating Look Back at the Compaq Presario 4402 from 1996, a Time When Compaq Put the Computer Inside the Monitor

Published

on

Compaq Presario 4402 All-in-One Computer 1996
In 1996, families looking for a home computer had the same old problem: a cluttered desk with different boxes, cables strung out everywhere, and setting it all up felt like launching a small rocket. Compaq responded with the Presario 4402, a stylish (for the time) all-in-one system that combined all of the necessary components into a single, large package.



Compaq introduced the Presario 4402 in mid-1996 as part of an effort to simplify home computing. It cost roughly $1,999, which is nearly $4,144 now, for a system that critics described as one of the few truly all-in-one packages available at the time. The design contained a 15-inch display, but only 13.8 inches showed a real image, and it was fastened on top of the computer’s internals, all squeezed into one enormous beige monstrosity. It was a mammoth, measuring 16 inches wide, 14.1 inches deep, and 15.2 inches tall, weighing a whopping 43 pounds.

Compaq Presario 4402 All-in-One Computer 1996
An Intel Pentium CPU ran at a respectable 133 MHz on a 66 MHz system bus, with RAM starting at 16 MB of EDO and expanding up to 128 MB with 60 ns modules. A 1.6 GB hard drive was used for storage, a 6x CD-ROM for software installation or audio disc playback, and a 1.44 MB floppy drive for file transfer to disk. The built-in speakers provided stereo sound, and a 33.6 kbps modem enabled dial-up access to the early internet and other services. Windows 95 came included with a Quick Restore CD to assist you fix problems if the system went wrong.

You could control the CD player from the front panel, so you could just insert an audio disc and modify the level without having to restart the computer. Finally, the system functioned as a speakerphone/answering machine, allowing you to keep your desk clutter-free. Then there came the matching remote, which allowed you to control several devices from across the room. The software bundle featured Microsoft Works for work and spreadsheets, Netscape Navigator for web browsing, and Compton’s Interactive Encyclopedia 1996 for quick lookups. You can also choose between CompuServe, America Online, and GNN internet access.

Critics at the time praised the Presario 4402 for its performance without requiring you to make too many compromises. One reviewer in particular stated that it was ideal for writing papers, playing games, or searching up information online, particularly if you were cramped in a small college dorm or family room with little space. The main disadvantage of the built-in display was that you couldn’t simply replace the screen when you needed to update; instead, you had to replace the entire system. Internal extension was feasible, however, thanks to a riser card that provided two ISA slots and one PCI slot for adding things like enhanced graphics.

Google made Gmail and Drive easier for AI agents to use

Published

on

A new command-line tool published to GitHub consolidates Workspace’s sprawling APIs into a single interface. It also signals how seriously the company is taking the agentic AI moment.


The tool, whose documentation describes it as “one CLI for all of Google Workspace, built for humans and AI agents,” is called gws. It provides unified command-line access to Gmail, Google Drive, Calendar, Docs, Sheets, Slides, Chat, and most other Workspace services.

But the more revealing detail is buried in the instructions: the documentation includes a dedicated integration guide for OpenClaw, the open-source AI agent that went viral in late January and has since become something of a Rorschach test for where agentic AI is headed.

Google’s decision to name-check OpenClaw in official documentation, even unofficial official documentation, is not something companies do by accident.

Why a command-line tool matters for AI agents

The 💜 of EU tech

The latest rumblings from the EU tech scene, a story from our wise ol’ founder Boris, and some questionable AI art. It’s free, every week, in your inbox. Sign up now!

Before GWS, an AI agent that wanted to search a Gmail inbox, pull a file from Drive, and update a Calendar event had to navigate three separate APIs, each with its own authentication flows, rate limits, and response formats. The process worked, but as PCWorld described it, it was “a royal pain.”

The new tool collapses that into a single interface. Every operation produces structured JSON output the format AI agents can parse reliably without the ambiguity that can derail graphical interfaces. Authentication is handled once via OAuth, then inherited by any agent that calls the tool.

Advertisement

The architecture has one particularly elegant feature: gws does not ship a static list of commands. Instead, it reads Google’s own Discovery Service at runtime and builds its entire command surface dynamically. When Google adds a new API endpoint, the tool picks it up automatically.

There is no version to update, no stale documentation to wrestle with. For agents designed to work across long time horizons, that self-updating quality is not a minor convenience; it is a meaningful reliability guarantee.

The repository also includes more than 100 pre-built “agent skills” covering common Workspace workflows: uploading files to Drive with automatic metadata, appending data to Sheets, scheduling Calendar events, forwarding Gmail attachments, and dozens of similar operations.

These are the discrete, composable building blocks that agent frameworks like OpenClaw are designed to chain together.

Advertisement

The OpenClaw connection

OpenClaw’s story has moved fast. The project was published in November 2025 by Peter Steinberger, an Austrian software developer, under the name Clawdbot, a name that drew a trademark complaint from Anthropic.

After a brief stint as Moltbot, it settled on OpenClaw in late January 2026. Within weeks, users had created 1.5 million agents using the platform; the GitHub repository accumulated nearly 200,000 stars. OpenClaw’s premise is simple enough to fit on a business card: AI that actually does things.

On 14 February, Sam Altman announced that Steinberger was joining OpenAI to lead the next generation of personal agents. OpenClaw would move into an independent open-source foundation that OpenAI would support. “The lobster is taking over the world,” Steinberger wrote in his farewell post. “My next mission is to build an agent that even my mum can use.”

Google’s Workspace CLI landing in the middle of that story, with OpenClaw integration instructions in the documentation, three weeks after Steinberger joined OpenAI, is the kind of timing that does not look accidental. Whether it reflects a deliberate competitive response, a coincidental release, or simply developers at Google shipping something that was already in progress is not confirmed.

Advertisement

What is clear is that a major platform company has now built infrastructure specifically to make its apps more useful for the open-source agent ecosystem that OpenAI just acquired the architect of.

MCP and the broader picture

Beyond OpenClaw, gws also functions as a Model Context Protocol server. MCP is the open standard for how AI agents communicate with external tools, originally developed by Anthropic and now adopted across the industry. Running gws mcp exposes Workspace APIs as structured tools that any MCP-compatible client, Claude Desktop, VS Code with AI extensions, or Google’s own Gemini CLI, can natively call.

That MCP support is significant because it means the tool is not merely an OpenClaw utility. It is infrastructure for the entire class of AI agents that is converging on MCP as a standard. Google is, in effect, making Workspace a first-class citizen in the emerging agent ecosystem, regardless of which model or framework is doing the work.

One important caveat: Google’s documentation explicitly notes that gws is “not an officially supported Google product.” It is published as a developer sample, meaning there are no guarantees of stability, security, or ongoing maintenance at the level of a production service. For individual developers and experimenters, that is a manageable risk.

Advertisement

For enterprises considering deploying AI agents against live Workspace data, it is a meaningful limitation, particularly given the ongoing concerns about OpenClaw’s security model, which a Cisco research team found vulnerable to data exfiltration and prompt injection via malicious third-party skills.

What Google is signalling

Addy Osmani, Director of Google Cloud AI, has framed his team’s focus as building infrastructure for agentic systems, those capable of generating command-line inputs and managing structured outputs across complex workflows. The Workspace CLI fits that vision directly.

The broader pattern is legible. Microsoft has Copilot Tasks. OpenAI now has the architect of OpenClaw. Google has its own Gemini agent stack, and now a CLI that makes its most widely-used productivity suite readable by any agent that speaks JSON and MCP.

The competition for where enterprise AI agents live and what data they can reach is accelerating, and the battleground increasingly looks like the infrastructure beneath the applications, not the applications themselves.

Advertisement

For now, gws is a GitHub repository with a caveat. But the 14,000 stars it accumulated before most journalists noticed suggest that developers who build agents for a living already understand what it means.

Grell OAE2 Open-Back Headphones Debut at CanJam NYC 2026 with Forward Projecting Soundstage You Have to Hear to Believe

Published

on

At CanJam NYC 2026 this past weekend, Grell’s latest design, the Grell OAE2 open back headphones, made their U.S. public debut. The $599 model builds on the original OAE1 and continues Grell’s pursuit of tonal accuracy, mechanical precision, and long-term listening comfort. The open back over ear design incorporates a newly optimized dynamic driver and an acoustically refined housing intended to improve airflow and project a more speaker like soundstage presentation in front of the listener.

Grell OAE2 Open-Back Headphones side
Grell OAE2

If you’ve spent enough time walking the halls at hi-fi shows, you know the routine. Every year a handful of startups promise they’ve reinvented the wheel and that what you’re about to hear will change everything you thought you knew about speakers or headphones. You nod politely, sit down, listen for a few minutes, and try not to roll your eyes when the demo playlist inevitably lands on Diana Krall, the Eagles, or Norah Jones.

But when the name on the badge is Axel Grell, you stop joking around and actually pay attention.

Grell is hardly another “trust us, it’s revolutionary” startup voice on a crowded show floor. Before launching his own brand, the veteran headphone engineer spent decades at Sennheiser, where he was responsible for developing some of the most respected high end headphones of the past few decades. Small German company. You might have heard of it. They also make a decent strudel.

How the Grell OAE2 Tries to Move the Soundstage Out of Your Head

Drop + Grell prototype headphone at CanJam SoCal 2023
Drop + Grell prototype headphone with forward mounted driver.

One of the biggest limitations of traditional headphones is the so called “in head” effect. Because the drivers sit millimeters from the ear and fire directly into the ear canal, most headphones create a listening perspective where instruments appear to originate from inside the listener’s head rather than from a believable space in front of them. While open back designs can widen the presentation and improve air and separation, they rarely change the fundamental geometry of how the sound reaches the ear. The result is often a presentation that feels spacious but still anchored inside the listener’s skull rather than resembling the externalized imaging produced by loudspeakers.

The Grell OAE2 open back headphones were engineered to address that specific limitation. Instead of following the conventional layout where the driver points straight into the ear canal, Axel Grell designed the acoustic structure so the output interacts more deliberately with the outer ear before entering the ear canal. This approach allows the pinna and surrounding ear structures to contribute to spatial cues in a way that more closely resembles how we hear speakers in a room.

In speaker listening, sound reaches the ear only after interacting with the head, shoulders, and outer ear, creating small timing, phase, and tonal variations that the brain uses to interpret direction, distance, and placement. By preserving more of those interactions inside the headphone structure, the OAE2 attempts to shift the listening perspective forward so that instruments appear positioned in front of the listener rather than inside the head.

The goal is not to artificially exaggerate soundstage width or create gimmicky spatial effects, but to maintain stable imaging, natural treble perception, and controlled low frequency behavior while presenting music in a way that resembles nearfield loudspeaker listening.

For listeners accustomed to the traditional headphone presentation, the perspective can initially feel unfamiliar, but the intention is that the brain adapts to the spatial cues over time, making the presentation feel more natural and less fatiguing during long listening sessions.

German Engineering, Replaceable Parts, and None of That Disposable Headphone Nonsense

Grell OAE2 Open-Back Headphones Flat

Beyond the acoustic design, the Grell OAE2 reflects Axel Grell’s long standing belief that premium headphones should be built to last. Instead of chasing short product cycles, the design emphasizes durability, serviceability, and long term ownership. In other words, the opposite of the sealed plastic approach that dominates much of the modern headphone market.

At the center of the OAE2 is a 40 mm wideband dynamic driver built around a bio cellulose diaphragm, paired with a carefully tuned damping system. Part of that system includes a precision manufactured stainless steel acoustic mesh produced in Germany, which helps regulate airflow and maintain consistent driver behavior. The goal is controlled acoustics rather than brute force tuning, supporting the headphone’s spatial presentation without introducing unwanted resonances or instability.

Construction follows a modular all metal architecture with replaceable components that can be serviced if parts wear out. The idea is simple: headphones should not become disposable because one component fails. Connectivity is equally straightforward. The OAE2 ships with two detachable 1.8 m cables, including a 3.5 mm single ended cable and a 4.4 mm balanced cable, along with a screw on 3.5 mm to 6.3 mm adapter for traditional headphone amplifiers and a protective carry case.

From a technical standpoint, the OAE2 remains close to the OAE1 but with small refinements. The circumaural open back design uses a dynamic transducer rated from 12 Hz to 34 kHz within ±3 dB, extending from 6 Hz to 46 kHz at -10 dB. Nominal impedance is 38 ohms with 100 dB sensitivity at 1 kHz (1 VRMS), making it compatible with portable players while still benefiting from a capable amplifier. Total harmonic distortion is rated at 0.05 percent at 1 kHz and 100 dB, and the headphone weighs 378 g (13.3 oz) without the cable attached. Slightly heavier than the OAE1 by three grams. German engineering apparently does not skip arm day.

The Germans Ran the Numbers. Now We Listen.

Grell OAE2 Headphones at CanJam NYC 2026
Grell OAE2 Headphones at CanJam NYC 2026

Grell kept things refreshingly simple at CanJam NYC 2026. No $30,000 source chain, no mystical demo playlist, and no attempt to overwhelm people with exotic gear. Just three pairs of the Grell OAE2, a few source devices, and a small stack of EarMen ST-Amp headphone amplifiers priced around $400.

The setup was about as straightforward as it gets for a show floor demo. The EarMen ST-Amp offers both single ended and balanced output options, rated at 0.5W into 32 ohms (4V) single ended and 1.85W into 32 ohms (7.75V) balanced, which is more than enough for a 38 ohm headphone like the OAE2. In other words, plenty of clean power but nothing exotic that might artificially inflate the listening experience.

Even the music selection avoided the usual trade show clichés. There were no sacred audiophile demo tracks looping endlessly in the background. Attendees could simply plug in their own phone and listen to whatever they wanted. Which I appreciated. I even spent a little time surfing through German tracks on the playlist. My German is… limited. Although if knowing Yiddish counts as partial credit, I was doing just fine.

A short run through Deadmau5, Daft Punk, and Aphex Twin was enough to get my attention. The OAE2 leans toward a neutral presentation without obvious boosts or dips across the spectrum. Clean, but not the sterile kind of clean that some German designs fall into. Bass is not tuned for exaggerated punch, but the definition and speed are excellent, especially with electronic music that depends on tight timing. The top end is equally well behaved. Detailed and open without any glare or hardness.

hirams-exterior

Then came the part that really mattered. Soundstage. The presentation is clearly wide, but not absurdly wide in the artificial sense. Think more East River to the IAC Building on the West Side Highway wide, not across the Hudson into New Jersey for chili dogs at Hiram’s wide. More important than width, however, is placement in front of the listener. If Axel Grell’s goal was to push the image outside the head and create what I would call a “nearface” listening perspective about 6 to 10 inches in front of you, the OAE2 largely succeeds.

Switching over to vocals confirmed that impression. Tracks from Amy Winehouse, Billie Holiday, Bjork, and Belinda Carlisle showed the same spatial behavior. Voices did not collapse into the center of the skull as they often do with headphones. Some appeared slightly closer, others further back, but the image remained focused and stable. Never diffuse. Always locked in dead center. And frankly, that was pretty impressive.

The Bottom Line

The Grell OAE2 stands out for one reason: it actually delivers on the promise of moving the soundstage out of your head and placing it slightly in front of the listener. The effect is not gimmicky or exaggerated. Instead, it feels closer to a nearfield speaker presentation with stable imaging and natural placement. Sonically the tuning leans neutral with clean treble, fast and well controlled bass, and no obvious peaks designed to impress in a quick demo.

Comfort was also encouraging. Clamping force is moderate, the headband is well padded, and the overall build quality feels appropriate for a headphone expected to retail for $599 / £499 / €499. Based on our first listen at CanJam NYC 2026, Axel Grell’s latest design shows real promise. A full review is coming later this month once we spend more time with a production unit.

5 Of The Worst Places To Store Your DeWalt Batteries

Published

on





We may receive a commission on purchases made from links.

Gone are the days when you had to be attached to the nearest wall whenever you needed to use a power tool. These days, the rise of electric power tools has introduced not just the convenience of a cordless workflow but also the benefits of a swappable battery system. With batteries that can work across multiple product lines, electric power tool fans can save time, effort, and storage space. Because of this, it’s no wonder that everyone from regular homeowners to professionals has invested in their own electric power tool systems, like DeWalt. However, it’s important to note that, while cordless power tools offer a lot of convenience, they still require maintenance.

While DeWalt is known for its trustworthiness, some of the most common issues with DeWalt power tool batteries include premature failure, overheating, and charging issues. And while some of these issues are just mildly annoying, others can cause harm both to you and your property. Like other power tool brands, DeWalt batteries are also at risk of typical lithium battery issues, including degradation, swelling, and fire. Apart from using it correctly and charging it only with legitimate chargers and tools, one of the most important things you can do to make your DeWalt batteries last longer is to keep them in the right place at the right time. So, if you’re committed to doing so, here are what you should avoid.

Advertisement

1. Inside your car (and other super hot places)

Leaving your power tool batteries inside vehicles can lead to many problems, from minor efficiency issues to permanent damage. However, the vehicle itself isn’t entirely the problem, but how it can be like an oven. After all, DeWalt states that anything above 105°F is a big no. According to DeWalt, this is because the chemicals inside it won’t be able to get the right reaction it needs to charge properly. In line with this, it’s best to keep the batteries out of the reach of anything that generates excessive heat, such as fireplaces or space heaters. It also goes without saying that you should avoid placing them anywhere else where they’re exposed to direct sunlight. For example, it’s best not to leave them outside on your workbench in the afternoon sun for too long.

If you do need to bring your DeWalt batteries with you for any reason, it’s also important to prepare them properly for transit, especially when traveling on a commercial plane. The United States Federal Aviation Administration (FAA) notes that, due to the inherent risk of lithium batteries, there are many restrictions on them. Because of this, DeWalt cautions FlexVolt battery users not to forget the red transport cap. Thankfully, if you do lose it, you can buy these separately. On Amazon, you can snag a replacement DeWalt 60V battery cap for under $10, which buyers have confirmed meets airline requirements.

2. Unheated garages or sheds

While heat can be a problem, the cold can also ruin your power tool batteries. In fact, DeWalt notes that anything below 40°F can cause similar problems to exposure to extreme heat. So, if you live in a country that regularly experiences freezing temperatures, you’ll need to be more mindful when moving your batteries to less volatile spaces. This can mean investing in insulating your garages, sheds, or workspaces.

If you have no choice but to leave your DeWalt batteries in a place with poor insulation, there are some things you can do that won’t break the bank. For example, some budget-friendly hacks for keeping your tool batteries safe in cold temperatures include using insulated bags or even a closed cooler. Similar to how these are designed to keep your beer cool in the summer, they’re also an ideal way to maintain a steady temperature in the winter. Just make sure no leftover ice or water is inside when you chuck your batteries in it.

But take note, it’s never a good idea to revive a power tool battery when it doesn’t seem to be charging, since the process can be both complicated and dangerous. Unless you’re a professional with access to the right parts or know the ins and outs of modern batteries, including the software, you’re likely better off sending it to the service center or replacing it with a fresh product.

3. Utility rooms

One common warning you’ll get from any lithium-powered battery is to keep it away from moisture and other liquids, which basically means humid environments are at the bottom of the list. Humidity can lead to corrosion that can affect the battery’s ability to function over time, leading to issues like battery deformation or even short circuiting. Because of this, places that tend to have fluctuating, humid temperatures, like utility rooms, should be avoided.

Like most of its portfolio, DeWalt batteries can’t be used when wet anymore. While there are cases of users claiming their batteries still work after dropping them in buckets or getting wet in the rain, this isn’t always the case. To help counter this, you can invest in something like DeWalt’s ToughSystem 2.0 Charger Box. Apart from being a charger for small electronic devices and your power tool batteries, the box itself is rated IP55. Although it still can’t be submerged and isn’t fully dust-tight, it does offer protection from low-pressure water jets (and a little bit of rain).

If you spot any corrosion you suspect is affecting your tool’s performance, it doesn’t mean you have to dispose of the batteries yet. After unplugging the battery from your tool or charger, you can use a baking soda paste to help remove it. But if it looks too far gone, you might as well send it over to the DeWalt service center for professional guidance (or at least free, guilt-free disposal).

4. Near potential fire hazards

For many of us, our garages house more than just our vehicles. Unless you’re a committed minimalist, it’s not uncommon for the average person to accumulate a lifetime’s worth of stuff, much of it functional and some of it sentimental. Because of this, it’s quite common to use the garages as a general storage space, including for tools. Unsurprisingly, many of us may find ourselves storing our power tool batteries alongside a ton of other items, which they probably should not be close to at all.

In general, there are certain things you should avoid storing in your garage or shed entirely, including your DeWalt batteries. Apart from temperature-sensitive perishables, like wine or food, it’s also good to find a home elsewhere for flammable items. If your DeWalt batteries do catch fire, things like paint cans, propane tanks, or even old paperwork can make the damage even more terrifying.

That said, this can be easier said than done, especially if you have a small space to begin with. To avoid this, it’s always a good idea to keep your garage organized to keep fires at bay, whether they are caused by your DeWalt batteries or not. By conducting regular inventories, creating designated workspaces, storing similar items together, and setting a maintenance schedule, you can both keep the clutter at bay and catch any issues with your power tools and their batteries.

5. Near conductive or corrosive items

In an ideal world, DeWalt batteries are supposed to last up to three years. However, among the many factors that can affect them are the number of charger cycles and small actions that can increase the rate of degradation, like not being careful with the terminals. If you’re wondering how to mess up this sensitive part of the battery, DeWalt mentions several ways to do so, such as avoiding conductive materials. In layman’s terms, this means things that can channel electricity, like keys or coins, should be stored away. For people who work with DeWalt batteries professionally, this can also mean hand tools or loose tools, such as nails, bolts, and screws. But while this can be a problem if you haphazardly throw your things into a random bag, this won’t be such a big concern if you are traveling with DeWalt’s TStak or ToughSystem.

Apart from this, it will also be a good idea to clean your DeWalt battery terminal regularly. Although things like sawdust, drywall dust, dirt, or oils are pretty common when you work with power tools, it’s important not to leave them on for too long. With just a few minutes of your time and a damp (not wet) cloth, you can remove particle buildup from your batteries. Just make sure to avoid any unnecessary solvents, so you don’t accidentally damage them.

NetEase is reportedly pulling funding for Yakuza creator’s studio

Published

on

The hype for Gang of Dragon, the debut game from Nagoshi Studio, may already be getting derailed. According to a Bloomberg report, Chinese tech giant NetEase is going to stop financing Nagoshi Studio starting in May. Bloomberg confirmed the news with the studio’s employees and a NetEase spokesperson.

The report explained that NetEase decided to cut funding to Nagoshi Studio, which was founded in 2021 by Yakuza franchise creator Toshihiro Nagoshi, after finding out the studio needed $44.4 million to complete the project. Bloomberg reported that Nagoshi Studio is trying to find new sponsors but hasn’t had any success so far. The report also added that the studio can continue the project on its own, but would be responsible for paying NetEase for any associated costs to hold onto the brand or assets.

While Nagoshi Studio may have been working on Gang of Dragon since the studio’s creation, the general public got a better look at the title through a trailer announcement during The Game Awards 2025. The action-adventure game set in Tokyo would star Ma Dong-Seok, a South Korean actor who starred in Train to Busan and Marvel’s Eternals. As of now, Nagoshi Studio might be at risk of joining other casualties stemming from NetEase’s executive decisions, like when the tech giant decided to shut down Ouka Studio in 2024.
