The acting inspector general says the Office of Personnel Management is investigating whether any “emerging threats” have arisen as Elon Musk’s DOGE works to rapidly transform government systems.

Another Silicon Valley investor is getting into the rocket business.

Former Google chief executive Eric Schmidt has taken a controlling interest in the Long Beach, California-based Relativity Space. The New York Times first reported the change becoming official, after Schmidt told employees in an all-hands meeting on Monday.

Schmidt's involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company's previous fundraising dried up.

Google has a new mission in the AI era: to add Gemini to as many of the company's products as possible. We've already seen Gemini appear in search results, text messages, and more. In Google's latest update to Workspace, Gemini will be able to add calendar appointments from Gmail with a single click. Well, assuming Gemini gets it right the first time, which is far from certain.

The new calendar button will appear at the top of emails, right next to the summarize button that arrived last year. The calendar option will show up in Gmail threads with actionable meeting chit-chat, allowing you to mash that button to create an appointment in one step. The Gemini sidebar will open to confirm the appointment was made, which is a good opportunity to double-check the robot. There will be a handy edit button in the Gemini window in the event it makes a mistake. However, the robot can't invite people to these events yet.

The effect of using the button is the same as opening the Gemini panel and asking it to create an appointment. The new functionality is simply detecting events and offering the button as a shortcut of sorts. You should not expect to see this button appear on messages that already have calendar integration, like dining reservations and flights. Those already pop up in Google Calendar without AI.

HP, along with other printer brands, is infamous for issuing firmware updates that brick already-purchased printers that have tried to use third-party ink. In a new form of frustration, HP is now being accused of issuing a firmware update that broke customers’ laser printers—even though the devices are loaded with HP-brand toner.

The firmware update in question is version 20250209, which HP issued on March 4 for its LaserJet MFP M232-M237 models. Per HP, the update includes “security updates,” a “regulatory requirement update,” “general improvements and bug fixes,” and fixes for IPP Everywhere. Looking back to older updates’ fixes and changes, which the new update includes, doesn’t reveal anything out of the ordinary. The older updates mention things like “fixed print quality to ensure borders are not cropped for certain document types,” and “improved firmware update and cartridge rejection experiences.” But there’s no mention of changes to how the printers use or read toner.

However, users have been reporting sudden problems using HP-brand toner in their M232–M237 series printers since their devices updated to 20250209. Users on HP’s support forum say they see Error Code 11 and the hardware’s toner light flashing when trying to print. Some said they’ve cleaned the contacts and reinstalled their toner but still can't print.

Pedro Pascal returns as Joel in The Last of Us S2.

HBO released a one-minute teaser of the hotly anticipated second season of The Last of Us—based on Naughty Dog's hugely popular video game franchise—during CES in January. We now have a full trailer, unveiled at SXSW after the footage leaked over the weekend, chock-full of Easter eggs for gaming fans of The Last of Us Part II.

(Spoilers for S1 below.)

The series takes place in the 20-year aftermath of a deadly outbreak of mutant fungus (Cordyceps) that turns humans into monstrous zombie-like creatures (the Infected, or Clickers). The world has become a series of separate totalitarian quarantine zones and independent settlements, with a thriving black market and a rebel militia known as the Fireflies making life complicated for the survivors. Joel (Pedro Pascal) is a hardened smuggler tasked with escorting the teenage Ellie (Bella Ramsay) across the devastated US, battling hostile forces and hordes of zombies, to a Fireflies unit outside the quarantine zone. Ellie is special: She is immune to the deadly fungus, and the hope is that her immunity holds the key to beating the disease.

A new patent could suggest that Apple may be ready to take VR gaming more seriously on the Apple Vision Pro—which is exactly what's needed to turn the device's fortunes around.

Like life itself, BMWs seemed less complicated last century. You didn't need a crib sheet to understand the badge, and body styles were mostly just sedans, with a smattering of station wagons, two-door coupes, and convertibles. That was before it helped kickstart the SUV craze; now instead of 3, 5, 7, the series run 2–8 and X1 through X7. And don't get me started on individual model names. Like the 2025 430i xDrive Gran Coupe.

At first glance, if you're middle-aged like the average Ars reader, your brain probably says "this is a 3 Series sedan." After all, it has a pair of doors on either side. But there is no requirement for a coupe to only have two doors: the name is derived from the French "couper," meaning cut. And indeed, the roofline is cut down more than 2 inches lower than the actual 3 Series.

There's also a hatch at the rear, rather than a trunk lid. So, technically it's a fastback body style, which BMW has decided to call Gran Coupe the way it calls station wagons Tourings. Pedantic pigeonholing of body style will probably take a back seat to discussion of the front grille, though.

A 55-year-old software developer faces up to 10 years in prison for deploying malicious code that sabotaged his former employer's network, allegedly costing hundreds of thousands of dollars in losses.

The US Department of Justice announced Friday that Davis Lu was convicted by a jury after "causing intentional damage to protected computers" reportedly owned by the Ohio- and Dublin-based power management company Eaton Corp.

Lu had worked at Eaton Corp. for about 11 years when he apparently became disgruntled by a corporate "realignment" in 2018 that "reduced his responsibilities," the DOJ said.

It has been an uncharacteristically messy start to the year for the world's leading spaceflight company, SpaceX.

Let's start with the company's most recent delay. The latest launch date for a NASA mission to survey the sky and better understand the early evolution of the Universe comes Monday night. The launch window for this SPHEREx mission opened on February 28, but a series of problems with integrating the rocket and payloads have delayed the mission nearly two weeks.

Then there are the Falcon 9 first stage issues. Last week, a Falcon 9 rocket launched nearly two dozen Starlink satellites into low-Earth orbit. However, one of the rocket's nine engines suffered a fuel leak during ascent. Due to a lack of oxygen in the thinning atmosphere, the fuel leak did not preclude the satellites from reaching orbit. But when the first stage returned to Earth, it caught fire after landing on a droneship, toppling over. This followed a similar issue in August, when there was a fire in the engine compartment. After nearly three years without a Falcon 9 landing failure, SpaceX had two in six months.

Google didn't explain exactly why it shipped a mandatory software update to the Pixel 4a, an Android phone from 2020, earlier this year. The nature of that update, which gave some models all but unusable battery life, provided some clues, as did later software analysis. But now, Australian authorities have provided a more concrete answer: battery overheating and fire risk.

The Australian Competition and Consumer Commission's (ACCC) Product Safety arm issued a recall for the Pixel 4a late last week. The reason, the commission said, is that Google's firmware update and battery changes served to "mitigate the risk of overheating" because "an overheating battery could pose a risk of fire and/or burns to a user."

In the US and elsewhere, Google's messaging did not use the term "recall." Google stated on its "Pixel 4a Battery Performance Program" page that "certain" Pixel 4a models "require a software update to improve the stability of their battery’s performance," which also "reduces available battery capacity and impacts charging performance." Google said it is still safe to charge a Pixel 4a.

Google has gotten its first taste of remedies that Donald Trump’s Department of Justice plans to pursue to break up the tech giant’s monopoly in search. In the first filing since Trump allies took over the department, government lawyers backed off a key proposal submitted by the Biden DOJ. The government won't ask the court to force Google to sell off its AI investments, and the way it intends to handle Android is changing. However, the most serious penalty is intact—Google's popular Chrome browser is still on the chopping block.

"Google’s illegal conduct has created an economic goliath, one that wreaks havoc over the marketplace to ensure that—no matter what occurs—Google always wins," the DOJ filing says. To that end, the government maintains that Chrome must go if the playing field is to be made level again.

The DOJ is asking the court to force Google to promptly and fully divest itself of Chrome, along with any data or other assets required for its continued operation. It is essentially aiming to take the Chrome user base—consisting of some 3.4 billion people—away from Google and hand it to a competitor. The government will vet any potential buyers to ensure the sale does not pose a national security threat. During the term of the judgment, Google would not be allowed to release any new browsers. However, it may continue to contribute to the open source Chromium project.

The Spark 2 from Positive Grid looks like a miniature old-school amp, but it is, essentially, a computer with some knobs and a speaker. It has Bluetooth, USB-C, and an associated smartphone app. It needs firmware updates, which can brick the device—ask me how I found this out—and it runs code on DSP chips. New guitar tones can be downloaded into the device, where they run as software rather than as analog electrical circuits in an amp or foot pedal.

In other words, the Spark 2 is the latest example of the "software-ization" of music.

Forget the old image of a studio filled with a million-dollar, 48-track mixing board from SSL or API and bursting with analog amps, vintage mics, and ginormous plate reverbs. Studios today are far more likely to be digital, where people record "in the box" (i.e., they track and mix on a computer running software like Pro Tools or Logic Pro) using digital models of classic (and expensive) amplifiers, coded by companies like NeuralDSP and IK Multimedia. These modeled amp sounds are then run through convolution software that relies on digital impulse responses captured from different speakers and speaker cabinets. They are modified with effects like chorus and distortion, which are all modeled, too. The results can be world-class, and they're increasingly showing up on records.

The giant extinct shark species known as the megalodon has captured the interest of scientists and the general public alike, even inspiring the 2018 blockbuster film The Meg. The species lived some 3.6 million years ago, and no complete skeleton has yet been found. So there has been considerable debate among paleobiologists about megalodon's size, body shape, and swimming speed, among other characteristics.

While some researchers have compared megalodon to a gigantic version of the stocky great white shark, others believe the species had a more slender body shape. A new paper published in the journal Palaeontologia Electronica bolsters the latter viewpoint, also drawing conclusions about the megalodon's body mass, swimming speed (based on hydrodynamic principles), and growth patterns.

As previously reported, the largest shark alive today, reaching up to 20 meters long, is the whale shark, a sedate filter feeder. As recently as 4 million years ago, however, sharks of that scale likely included the fast-moving predator megalodon (formally Otodus megalodon). Due to incomplete fossil data, we're not entirely sure how large megalodon were and can only make inferences based on some of their living relatives.
