The Federal Trade Commission is moving to push back a trial set to determine if Amazon tricked customers into signing up for Prime subscriptions.

At a Zoom status hearing on Wednesday, the FTC officially asked US District Judge John Chun to delay the trial. According to the FTC's attorney, Jonathan Cohen, the agency needs two months to prepare beyond the September 22 start date, blaming recent "staffing and budgetary shortfalls" stemming from the Trump administration’s Department of Government Efficiency (DOGE), CNBC reported.

"We have lost employees in the agency, in our division, and on our case team," Cohen said, explaining that "there is an extremely severe resource shortfall in terms of money and personnel," Bloomberg reported. Cuts are apparently so bad, Cohen told Chun that the FTC is stuck with a $1 cap on any government credit card charges and "may not be able to purchase the transcript from Wednesday’s hearing," Bloomberg reported.

Hand clapping is ubiquitous behavior for humans across time and cultures, serving many different purposes: to signify approval with applause, for instance, or to keep time to music. Acousticians often use a hand clap as a cheap substitute for pricey equipment to make acoustic measurements in architecture. While the basic physical mechanism is simple, the underlying physical mechanisms are less well-understood.

A new paper published in the journal Physical Review Research provides experimental support for the hypothesis that hand clapping essentially acts like a Helmholtz resonator—akin to the hum generated by blowing across the top of a bottle, or the hiss one hears when holding a conch shell to one's ear.

In 2020, engineers Nikolaos Papadakis and Georgios Stavroulakis, both at the Technical University of Crete, recruited 24 students to clap their hands once in different venues, varying their hand configurations in 11 different ways—changing the angle of the hands with respect to one another, for instance, or changing how many fingers of one hand overlapped with the fingers or palms of the other.

Most new AI models go big—more parameters, more tokens, more everything. Google's newest AI model has some big numbers, but it's also tuned for efficiency. Google says the Gemma 3 open source model is the best in the world for running on a single GPU or AI accelerator. The latest Gemma model is aimed primarily at developers who need to create AI to run in various environments, be it a data center or a smartphone. And you can tinker with Gemma 3 right now.

Google claims Gemma 3 will be able to tackle more challenging tasks compared to the older open source Google models. The context window, a measure of how much data you can input, has been expanded to 128,000 from 8,192 tokens in previous Gemma models. Gemma 3, which is based on the proprietary Gemini 2.0 foundation, is also a multimodal model capable of processing text, high-resolution images, and even video. Google also has a new solution for image safety called ShieldGemma 2, which can be integrated with Gemma to help block unwanted images in three content categories: dangerous, sexual, or violent.

Most of the popular AI models you've heard of run on collections of servers in a data center, filled to the brim with AI computing power. Many of them are far too large to run on the kind of hardware you have at home or in the office. The release of the first Gemma models last year gave developers and enthusiasts another low-hardware option to compete with the likes of Meta Llama3. There has been a drive for efficiency in AI lately, with models like DeepSeek R1 gaining traction on the basis of lower computing costs.

Authors think that Meta's admitted torrenting of a pirated books data set used to train its AI models is evidence enough to win their copyright fight—which previously hinged on a court ruling that AI training on copyrighted works isn't fair use.

Moving for summary judgment on a direct copyright infringement claim on Monday in a US district court in California, the authors alleged that "whatever the merits of generative artificial intelligence, or GenAI, stealing copyrighted works off the Internet for one’s own benefit has always been unlawful."

In their filing, the authors accused Meta of brazenly deciding to torrent terabytes of pirated book data after attempts to download pirated books one by one "posed an immense strain on Meta's networks and proceeded very slowly."

Lately, SpaceX founder Elon Musk has taken an aggressive posture toward Europe. He has called for the United States to exit NATO, a strategic alliance that has been the bedrock of trans-Atlantic cooperation since the end of World War II. Musk has also championed right-wing populism that seeks to topple existing governments on the continent.

And then there's Musk's increasingly antagonistic attitude toward Ukraine, a country viewed by many Europeans as a bulwark against further Russian aggression. This threatens the availability of a vital link in Ukraine's military, Starlink.

Musk's world-class satellite technology has provided lifesaving connectivity to citizens and soldiers in Ukraine. It has increased the country's offensive capabilities. And yet Musk could shut off his Starlink service anywhere in the world with an email.

Robotics firm iRobot, originator of the robotic vacuum Roomba facing stiff competition from lower-priced competitors, told investors Tuesday that there was "substantial doubt" about the company's survival "as a going concern" in the next year or so.

Investors took iRobot at its word, and its stock price had fallen nearly 40 percent as of 10:20 am Wednesday from the day before. The dire accounting language and market reaction are nothing new for tech firms, but iRobot's annual report suggests deeper issues than investor confidence. The company saw revenue drop 47 percent in the fourth quarter, it is actively seeking to renegotiate its largest loans, and it has launched a "formal strategic review" to consider refinancing, sale, or other alternatives.

The shaky world of consumer robotics

iRobot's fortunes have changed dramatically since 2022, when Amazon announced a $1.7 billion bid to buy the struggling but prominent firm.

Earlier today, Toyota and Lexus debuted some improved and some new electric vehicles. The event was focused on the European market, where battery EV penetration is relatively high, and I wouldn't expect either the Urban Cruiser or C-HR+ crossovers to show up on sale in the US. But we'll likely find the upgrades to the Toyota bZ4x and the closely related Lexus RZ, or at least some of them, in North American models at some point.

The revised bZ4x will come in three powertrain options, at least in the EU, all with new battery packs. There's a 165 hp (123 kW) front-wheel drive version coupled to a smaller-capacity 57.7 kWh battery pack (which I would not expect to come to the US), and then 221 hp (165 kW) FWD and 337 (252 kW) all-wheel drive options, both of which use a new 73.1 kWh battery pack.

For comparison, the bZ4xs that went on sale in the US several years ago are offered with either a 71.4 kWh pack for FWD or a 72.8 kWh pack for AWD versions.

With all the announcements from automakers planning for more gasoline and hybrid cars in their future lineups, you'd think that electric vehicles had stopped selling. While that might be increasingly true for Tesla, everyone else is more than picking up the slack. According to analysts at Rho Motion, global EV sales are up 30 percent this year already. Even here in the US, EV sales were still up 28 percent compared to 2024, despite particularly EV-unfriendly headwinds.

Getting ahead of those unfriendly winds may actually be driving the sales bump in the US, where EV sales only grew by less than 8 percent last year, for contrast. "American drivers bought 30 percent more electric vehicles than they had by this time last year, making use of the final months of IRA tax breaks before the incentives are expected to be pulled later this year," said Charles Lester, Rho Motion data manager.

With the expected loss of government incentives and the prospect of new tariffs that will add tens of thousands of dollars to new car prices, now is probably a good time to buy an EV if you think you're going to want or need one.

"The future of podcasting shouldn't be locked behind walled gardens," writes the team at Pocket Casts. To push that point forward, Pocket Casts, owned by the company behind WordPress, Automattic Inc., has made its web player free to everyone.

Previously available only to logged-in Pocket Casts users paying $4 per month, Pocket Casts now offers nearly any public-facing podcast feed for streaming, along with controls like playback speed and playlist queueing. If you create an account, you can also sync your playback progress, manage your queue, bookmark episode moments, and save your subscription list and listening preferences. The free access also applies to its clients for Windows and Mac.

"Podcasting is one of the last open corners of the Internet, and we’re here to keep it that way," Pocket Casts' blog post reads. For those not fully tuned into the podcasting market, this and other statements in the post—like sharing "without needing a specific platform's approval" and "podcasts belong to the people, not corporations"—are largely shots at Spotify, and to a much lesser extent other streaming services, which have sought to wrap podcasting's originally open and RSS-based nature inside proprietary markets and formats.

Media Matters for America (MMFA) has a plan to potentially defuse Elon Musk's "thermonuclear" lawsuits filed so far in three cities around the world, which accuse the nonprofit media watchdog organization of orchestrating a very costly X ad boycott.

On Monday, MMFA filed a complaint in a US district court in San Francisco, alleging that X violated its own terms of service by suing MMFA in Texas, Dublin, and Singapore. According to the TOS, MMFA alleged, X requires any litigation over use of its services to be "brought solely in the federal or state courts located in San Francisco County, California, United States."

"X Corp.’s decision to file in multiple jurisdictions across the globe is intended to chill Media Matters’ reporting and drive up costs—both of which it has achieved—and it is directly foreclosed by X’s own Terms of Service," MMFA's complaint said.

The AI industry is doing its best to will "agents"—pieces of AI-driven software that can perform multistep actions on your behalf—into reality. Several tech companies, including Google, have emphasized agentic features recently, and in January, OpenAI CEO Sam Altman wrote that 2025 would be the year AI agents "join the workforce."

OpenAI is working to make that promise happen. On Tuesday, OpenAI unveiled a new "Responses API" designed to help software developers create AI agents that can perform tasks independently using the company's AI models. The Responses API will eventually replace the current Assistants API, which OpenAI plans to retire in the first half of 2026.

With the new offering, users can develop custom AI agents that scan company files with a file search utility that rapidly checks company databases (with OpenAI promising not to train its models on these files) and navigates websites—similar to functions available through OpenAI's Operator agent, whose underlying Computer-Using Agent (CUA) model developers can also access to enable automation of tasks like data entry and other operations.

Apple on Tuesday patched a critical zero-day vulnerability in virtually all iPhones and iPad models it supports and said it may have been exploited in “an extremely sophisticated attack against specific targeted individuals” using older versions of iOS.

The vulnerability, tracked as CVE-2025-24201, resides in Webkit, the browser engine driving Safari and all other browsers developed for iPhones and iPads. Devices affected include the iPhone XS and later, iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later. The vulnerability stems from a bug that wrote to out-of-bounds memory locations.

Supplementary fix

“Impact: Maliciously crafted web content may be able to break out of Web Content sandbox,” Apple wrote in a bare-bones advisory. “This is a supplementary fix for an attack that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.)”

Nvidia has launched all of the GeForce RTX 50-series GPUs that it announced at CES, at least technically—whether you're buying from Nvidia, AMD, or Intel, it's nearly impossible to find any of these new cards at their advertised prices right now.

But hope springs eternal, and newly leaked specs for GeForce RTX 5060 and 5050-series cards suggest that Nvidia may be announcing these lower-end cards soon. These kinds of cards are rarely exciting, but Steam Hardware Survey data shows that these xx60 and xx50 cards are what the overwhelming majority of PC gamers are putting in their systems.

The specs, posted by a reliable leaker named Kopite and reported by Tom's Hardware and others, suggest a refresh that's in line with what Nvidia has done with most of the 50-series so far. Along with a move to the next-generation Blackwell architecture, the 5060 GPUs each come with a small increase to the number of CUDA cores, a jump from GDDR6 to GDDR7, and an increase in power consumption, but no changes to the amount of memory or the width of the memory bus. The 8GB versions, in particular, will probably continue to be marketed primarily as 1080p cards.

Scientists have long understood that microbes, zooplankton, and fish are vital sources of recycled nitrogen in coastal waters. But whales and other marine mammals like seals also help in this regard by releasing tons of nutrient-rich fecal matter into those waters. Now we can add whale urine to that list, according to a paper published in the journal Nature Communications.

“Lots of people think of plants as the lungs of the planet, taking in carbon dioxide, and expelling oxygen,” said co-author Joe Roman, a biologist at the University of Vermont. “For their part, animals play an important role in moving nutrients. Seabirds transport nitrogen and phosphorus from the ocean to the land in their poop, increasing the density of plants on islands. Animals form the circulatory system of the planet—and whales are the extreme example.”

Back in 2010, Roman co-authored a study in which they examined field measurements and population data to determine that whales and seals could be responsible for replenishing 2.3×104 metric tons of nitrogen per year in the Gulf of Maine alone. Specifically, they feed in deeper waters and then release "flocculent fecal plumes" (i.e., feces) at the surface, serving as a kind of "whale pump" that boosts plankton growth, among other tangible benefits.

Two people in Oklahoma have likely contracted measles infections linked to a mushrooming outbreak that began in West Texas, which has now risen to at least 258 cases since late January.

On Tuesday, Oklahoma's health department reported that two people had "exposure associated with the Texas and New Mexico outbreak" and then reported symptoms consistent with measles. They're currently being reported as probable cases because testing hasn't confirmed the infections.

There was no information about the ages, vaccination status, or location of the two cases. The health department said that the people stayed home in quarantine after realizing they had been exposed. In response to local media, a health department spokesperson said it was withholding further information because "these cases don’t pose a public health risk and to protect patient privacy."

The long-running rumors and hints that Microsoft is planning to enter the portable gaming market accelerated forward this week. That's thanks to a Windows Central report that Microsoft is planning to partner with a "PC gaming OEM" for "an Xbox-branded gaming handheld" to be released later this year. The device, code-named Keenan, will reportedly feature "Xbox design sensibilities," such as the branded Xbox guide button, but will almost certainly be a PC gaming device running Windows at its core.

Any Microsoft entry into the world of gaming handhelds will join a market that has become quite crowded in the wake of the Steam Deck's success. To make its own portable gaming effort stand apart, Microsoft will have to bring something unique to the table. Here are some of the features we're hoping will let Microsoft do just that.

For decades, Windows has been designed first and foremost for the world of large monitors driven by a mouse and keyboard world. When hardware makers try to simply stick that OS into a handheld screen size controlled by buttons and analog sticks, the results can be awkward at best.

When Ars finally drove the single-motor BMW i4 eDrive40 last year, we came away very impressed. Until then we'd only sampled the powerful twin-motor i4 M50, which is fast and fun but a bit too expensive, and it gives away a little too much range in the process. But neither of those is the model most people will buy. All-wheel drive is non-negotiable to car buyers in many parts of the country, and that means they want this one: the i4 xDrive40 Gran Coupe.

If the pictures are giving you a bit of deja vu, that's perfectly normal. Yes, it looks a lot like the BMW 430i Gran Coupe we reviewed yesterday, and the two cars share a lot more than just the CLAR platform that underpins much of BMW's current lineup.

All things being equal, designing a vehicle to be an electric vehicle from the ground up involves many fewer compromises than using a platform that has to cater not just to batteries and electric motors but also internal combustion engines and transmissions and gas tanks.

Vodafone, a British telecommunications firm, will withhold bonuses from employees who fail to comply with its return-to-office (RTO) policy, The Register reported this week.

Last week, Vodafone reminded employees of its RTO policy requiring workers to be in-office “2–3 times a week, or at least eight days a month," according to a memo viewed by The Register. The memo also reportedly detailed the consequences of failing to adhere to the policy, which sets a guideline for compliance by the end of the company's first fiscal quarter in July:

Employees who are not fully compliant with our hybrid working policy by the end of Q1 may be subject to disciplinary action in line with policy. Continued non-compliance with attendance expectations could result in a final written warning, which would mean individuals are not meeting the minimum performance standards and therefore would not be eligible for a bonus in 2026 or in subsequent years in which a final warning is given.

The strict policy comes as tech and other firms struggle to get employees to voluntarily return to offices. In desperation, some companies have resorted to tactics like tracking employee badge swipes and VPNs. Vodafone is looking to lure employees into the office by threatening their income, similar to Dell’s approach of making remote workers ineligible for promotions.

Google recently killed the Chromecast brand, but the dongles live on—mostly. Owners of the second-generation Chromecast and Chromecast Audio have noticed this week that their beloved streaming gadgets are no longer working. It appears that Google configured the devices with a single 10-year certificate that has now expired, and updating it is no simple feat. Google is looking into a fix, and there's nothing you can do in the meantime. In fact, trying to fix this yourself might only make things worse.

Beginning this week, attempting to connect your phone to a second-gen Chromecast or Chromecast Audio results in untrusted device or authentication errors. The unhelpful popup suggests this could be due to outdated firmware, which is technically true. Some wondered if this was simply Google's way of putting the decade-old device out to pasture.

One industrious Redditor has identified the dongle's certificate chain with a line reading "NotAfter: Mar 9 16:44:39 2025 GMT." Google may have included a 10-year certificate with the intention of updating it, or perhaps plans to switch to a rotating certificate fell through the cracks, or maybe no one had a plan because Google didn't expect these $35 devices to still be so popular a decade later—all things are possible in Google product support.

Elon Musk is now claiming that bad actors in Ukraine are behind an alleged cyberattack that caused outages on his social media platform X on Monday.

In an interview, Musk told Fox Business that he believes the attack came from "IP addresses originating in the Ukraine area."

Musk admitted that "we don't know exactly what happened"—nodding as his comments were characterized as a suspicion and discussing no evidence—but alleged that the attackers were trying to take down the entire X platform.
