Sony Honda Mobility, the automotive venture from two of Japan’s most storied companies, has swung the axe on its EV project. In a statement, it said it would “discontinue the development and launch” of the Afeela 1 and 2, its long-in-development electric cars. The company added it would review its “business direction,” and announce its future plans “at the earliest possible opportunity.” Which, if we’re honest, probably means the whole thing is going to be shut down, or scaled back so much it’s no longer worth talking about.

2026 has not been a great year for Honda. On March 12, it posted an up-to $15.7 billion loss as it wrote off a big chunk of its investment in EVs. The US’ pivot toward fossil fuels, removal of federal EV tax credits and the imposition of tariffs has hit its business pretty hard. Not to mention the high-profile embarrassment of its current F1 engine project with Aston Martin, which promised so much and has delivered less than nothing.

Sony’s journey into the automotive world began six years ago with the announcement of the Vision-S, the car which would eventually be re-christened Afeela. But while the product looked good on trade show stands, it stood still while the rest of the car world sprinted ahead. In January, Tim Stevens said Afeela 1 looked a little dated, and a little lacking in emotion, and a lot more expensive than comparable models from rivals. Not to mention that Afeela 1 is a sedan, being sold to a world that’s increasingly fallen out of love with the type in favor of higher-riding SUVs. In Sony’s statement, however, the SUV-aping Afeela 2 didn’t even get a mention by name, which hints that it was as much an afterthought for the company as we might have guessed when it was announced.

OpenAI is finally addressing one of the most frustrating things about working with files in ChatGPT. The company is rolling out two new features to help users quickly access previously uploaded files, including a Recent files menu and a dedicated Library tab.

How do ChatGPT’s new file management features work?

Until now, files in ChatGPT were largely tied to individual conversations, which meant finding them often involved going back to the original chat and scrolling through long threads. The new Recent files option in the attachment menu now lists some of the files you’ve used most recently, making it easier to jump back into ongoing work without digging through older chats.

On the web, there’s also a new Library tab in the sidebar. This acts as a central hub for all your uploaded and generated files, giving you a more organized view instead of tying everything to separate conversations. You can browse, search, and quickly attach files to new chats from this tab.

OpenAI also says ChatGPT can answer questions about files you’ve already uploaded, so you don’t need to reupload them every time you want more insights. Together, these changes make file reuse faster and far less tedious, especially if you regularly juggle files across multiple sessions.

Who’s getting access, and when?

The update is rolling out globally to ChatGPT Plus, Pro, and Business subscribers. Those in the EU, Switzerland, and the UK will have to wait a bit longer, with availability in these regions expected soon. There’s no word yet on whether these features will make their way to the free tier.

With these changes, OpenAI is continuing to position ChatGPT as more than just a chatbot, gradually turning it into a tool for managing ongoing work across conversations.

X is updating its revenue-sharing incentives to give more weight to engagement from a user’s home region, Nikita Bier, the company’s Head of Product has announced. Bier said the change in policy was to “encourage content that resonates with people in [the user’s] country, in neighboring countries and people who speak [their] language.”

Bier continued that while X appreciates everyone’s opinion on US politics, the company is hoping the new policy can “disincentivize gaming the attention of US or Japanese accounts.” The US and Japan have the largest number of users on X. Bier didn’t mention it outright, but dozens of popular accounts tweeting pro-Trump sentiments and commentaries focusing on US politics in general were revealed to be based outside the US late last year, when X rolled out a transparency feature that exposed users’ locations. Those accounts, which pretended to be from the US and garnered millions of likes, views and reposts, turned out to be based in countries like India, Kenya and Nigeria.

“X will be a much richer community when there’s relevant posts for people in all parts of the world,” Bier said. When one user responded to his post that some countries barely have any users, making it hard to earn money from the website, Bier just suggested that they should write about their day-to-day experiences. “Of course, you’re welcome to continue chiming in on America politics. We just won’t send money overseas for that content,” he said. X’s new policy will start taking effect on Thursday, March 26.

Since Donald Trump’s war on Iran started more than three weeks ago, United States military forces have allegedly attacked more than 9,000 sites, creating a climate of fear and constant uncertainty for Iranians in Tehran and across the country. Without an advanced warning system from the government, and amid the longest internet shutdown in Iran’s history, Iranians are left in an information void.

Even before Israel and the United States began dropping bombs, Iran’s lack of a public emergency alert tool and severe state-controlled digital oppression has impacted tens of millions of citizens. Since the 12-day Israel-Iran war last year, though, a group of Iranian digital rights activists and volunteers has been working to fill the gap with a dynamic, regularly updated mapping platform called Mahsa Alert. The project can’t replace real-time early alerts that could come from a coordinated government service, but the tool sends push notifications when Israeli forces warn about attacks, details some confirmed strike locations, and offers offline mapping capabilities.

“There is no emergency alert in Iran,” says Ahmad Ahmadian, the president and CEO of US-based digital rights group Holistic Resilience, which is behind Mahsa Alert and has been developing the platform since last summer. “This was where we saw the traction, we saw the need, and we continued working on it with the volunteers, with some [open source intelligence] experts, and used this to map the repression machinery ecosystem of Iran and surveillance.”

Mahsa Alert is a website but also has Android and iOS apps, which were intentionally designed to be lightweight and easy to use on any device. Given the heavy government connectivity control inside Iran and erratic access to the internet, volunteers also prioritized engineering the platform for offline use. And it can be easily updated if a user does get connectivity for a brief period by downloading APK files that contain new data. The team works to keep these updates extremely small; a recent release was 60 kilobytes, and Ahmadian says they are typically no more than 100 kilobytes.

One overlay on Mahsa Alerts plots the locations of “confirmed attacks” that Ahmadian says his team or other OSINT investigators have verified, using video footage or images that are submitted to a Telegram bot or shared on social media. There are also warnings about areas where Israeli forces have issued evacuation alerts, along with the crucial component of people submitting reports on what is happening around them.

“We have to go through a due diligence and verification process and tag them before putting them on the map,” Ahmadian says of the reported attacks and incidents, adding that the team has a backlog of more than 3,000 reports that it is working through or is unable to verify. Along with attempting to map strikes, the team behind Mahsa Alert have also plotted “danger zones” that could be at risk of attack—such as sites linked to Iran’s nuclear program or military—so ordinary citizens can stay away from them. Ahmadian claims 90 percent of attacks it has confirmed were at sites that were already present on the map. “Some of them that we can confirm, we do it because [a user] has shared a photo or they have shared some details that makes them verifiable,” he says.

The map also includes locations of thousands of CCTV cameras, suspected government checkpoints, and other domestic infrastructure. Medical facilities, such as hospitals and pharmacies, are included on the map along with other resources like the locations of religious sites and past protests.

Mahsa Alert has become more visible on global social media feeds as Iranians around the world share details from the map, encouraging people to look into the service and flagging it for friends and family who could use it as a resource. “The app went from near zero to over 100,000 daily active users in a matter of days,” Ahmadian says, adding that in total there have been around 335,000 users this year, with people first turning to the app during the Iranian regime’s brutal crackdown on anti-government protesters in January. Through the limited user information the app collects, Ahmadian claims there are signs that 28 percent of users are accessing the platform from inside Iran.

Last week’s Nvidia GTC conference highlighted new chip architectures to power AI. But as the chips become faster and more powerful, the remainder of data center infrastructure is playing catchup. The power delivery community is responding: Announcements from Delta, Vertiv, and Eaton showcased new designs for the AI era. Complex and inefficient AC to DC power conversions are gradually being replaced by DC configurations, at least in hyperscale data centers.

“While AC distribution remains deeply entrenched, advances in power electronics and the rising demands of AI infrastructure are accelerating interest in DC architectures,” says Chris Thompson, vice president of advanced technology and global microgrids at Vertiv.

AC to DC Conversion Challenges

Today, nearly all data centers are designed around AC utility power. The electrical path includes multiple conversions before power reaches the compute load. Power typically enters the data center as medium-voltage AC (1kV to 35kV), is stepped down to low-voltage AC (480V or 415V) using a transformer, converted to DC inside an uninterruptible power supply (UPS) for battery storage, converted back to AC, and converted again to low-voltage DC (typically 54 V DC) at the server, supplying the DC power computing chips actually require.

“The double conversion process ensures the output AC is clean, stable and suitable for data center servers,” says Luiz Fernando Huet de Bacellar, vice president of engineering and technology at Eaton.

That setup worked well enough for the amounts of power required by traditional data centers. Traditional data center computational racks draw on the order of 10 kW each. For AI, that is starting to approach 1 MW. At that scale, the energy losses, current levels, and copper requirements of AC to DC conversions become increasingly difficult to justify. Every conversion incurs some power loss. On top of that, as the amount of power that needs to be delivered grows, the sheer size of the convertors, as well as the connector requirements of copper busbars, becomes untenable. According to an Nvidia blog, a 1 MW rack could require as much as 200 kg of copper busbar. For a 1 GW data center, it could amount to 200,000 kg of copper.

Benefits of High-Voltage DC Power

By converting 13.8 kV AC grid power directly to 800 VDC at the data center perimeter, most intermediate conversion steps are eliminated. This reduces the number of fans and power supply units, and leads to higher system reliability, lower heat dissipation, improved energy efficiency, and a smaller equipment footprint.

“Each power conversion between the electric grid or power source and the silicon chips inside the servers causes some energy loss,” says Fernando.

Switching from 415 V AC to 800 V DC in electrical distribution enables 85 percent more power to be transmitted through the same conductor size. This happens because higher voltage reduces current demand, lowering resistive losses and making power transfer more efficient. Thinner conductors can handle the same load, reducing copper requirements by 45 percent, a 5 percent improvement in efficiency, and 30 percent lower total cost of ownership for GW-scale facilities.

“In a high-voltage DC architecture, power from the grid is converted from medium-voltage AC to roughly 800 V DC and then distributed throughout the facility on a DC bus,” said Vertiv’s Thompson. “At the rack, compact DC-DC converters step that voltage down for GPUs and CPUs.”

A report from technology advisory group Omdia claims that higher voltage DC data centers have already appeared in China. In the Americas, the Mt. Diablo Initiative (a collaboration among Meta, Microsoft, and the Open Compute Project) is a 400 V DC rack power distribution experiment.

A handful of vendors are trying to get ahead of the game. Vertiv’s 800 V DC ecosystem that integrate with NVIDIA Vera Rubin Ultra Kyber platforms will be commercially available in the second half of 2026. Eaton, too, is well advanced in its 800 V DC systems innovation courtesy of a medium-voltage solid-state transformer (SST) that will sit at the heart of DC power distribution system. Meanwhile Delta, has released 800 V DC in-row 660kW power racks with a total of 480 kW of embedded battery backup units. And, SolarEdge is hard at work on a 99%-efficient SST that will be paired with a native DC UPS and a DC power distribution layer.

But much of the industry is far behind. Patrick Hughes, senior vice president of strategy, technical, and industry affairs for the National Electrical Manufacturers Association, says most innovation is happening at the 400 V DC level, though some are preparing 800 V DC. He believes the industry needs a complete, coordinated ecosystem, including power electronics, protection, connectors, sensing, and service‑safe components that scale together rather than in isolation. That, in turn, requires retooling manufacturing capacity for DC‑specific equipment, expanding semiconductor and materials supply, and clear, long‑term demand commitments that justify major capital investment across the value chain.

“Many are taking a cautious approach, offering limited or adapted solutions while waiting for clearer standards, safety frameworks, and customer commitments,” said Hughes. “Building the supply chain will hinge on stabilizing standards and safety frameworks so suppliers can design, certify, manufacture, and install equipment with confidence.”

Gamers have long been searching for a computer that can be slipped into a coat pocket and used to complete tasks, a dream that now appears to be within reach due to a creative designer who wrapped a Razer Edge tablet within a custom 3D printed shell.

Flip the lid open and a familiar tablet screen greets you, cleanly framed in black plastic with just enough orange trim to make its intentions clear. A compact Bluetooth keyboard sits snugly in the base, and when everything is folded shut the whole thing is no bigger than a large phone, slim enough to disappear into a pocket or bag without a second glance. Those orange accents on the hinges and keycaps are a quiet reminder that this is anything but an ordinary device.

The project started with a Razer Edge picked up for around $80, a tablet that had largely faded from the spotlight since its release but still packed a capable Qualcomm Snapdragon G3x Gen 1 processor, plenty of RAM, and Android 12 under the hood. It came without the original controllers, but at that price it was too good a candidate to pass up.

There were already some design files floating around online for modular clamshells that could hold a phone, so it was just a matter of modifying them a little to fit the Razer Edge. Then it was simply a matter of using free editing software to make the necessary changes and printing them on a regular consumer printer. This all came together with simple screws and pins for the hinges, and a few lock sliders on the front keep the whole thing shut securely when you’re traveling.

The major challenge was getting the tablet inside without damaging it. A metal ring affixed to the rear of the Razer Edge, combined with a MagSafe-style adaptor on the case, locked everything together with powerful magnets that can be peeled away with some moderate coaxing. The tablet can leave the shell in seconds and return to becoming a tablet whenever it feels like it. The keyboard simply fits into a little tray in the bottom and automatically pairs over Bluetooth. Given its size, the layout is quite decent, and all of the shortcuts for doing daily tasks are available. When the lid closes, everything tucks neatly against the screen.

Power it up and things get interesting fast. Android 12 handles all the everyday essentials without breaking a sweat, and cloud streaming over Wi-Fi or mobile broadband opens up a much bigger games library on top of that. Emulation is where it really shines though, running GameCube titles at 720p with a solid frame rate and pushing PlayStation 2 games to 1.75 times their native resolution on many titles. Lighter PC games load up through dedicated apps and run without issue, and for anyone feeling nostalgic there is even a Windows 98 simulator tucked in there for good measure.
