France's competition regulator fined Apple €150 million, saying the iPhone maker went overboard in its implementation of pop-up messages that let users consent to or reject tracking that third-party applications use for targeted advertising.

The App Tracking Transparency (ATT) framework used by Apple on iPhones and iPads since 2021 makes the use of third-party applications too complex and hurts small companies that rely on advertising revenue, said a press release today by the Autorité de la concurrence (Competition Authority). The system harms "smaller publishers in particular since, unlike the main vertically integrated platforms, they depend to a large extent on third-party data collection to finance their business," the agency said.

User consent obtained via the ATA framework "authorizes the application in question to collect user data for targeted advertising purposes," the agency said. "If consent is given, the application can access the Identifier for Advertisers ('IDFA'), the identifier by which each device can be tracked through its use of third-party applications and sites." The French investigation was triggered by a complaint lodged by advertising industry associations.

If you're still using a computer you bought during the Clinton administration, interesting news: Crystal Dew World, developers of apps like CrystalDiskInfo and CrystalDiskMark, have released an update to their CrystalMark Retro benchmark (as spotted by Tom's Hardware). The most interesting aspect of the update for retro computing enthusiasts is expanded operating system support: the app will now run on Windows 95, Windows 98, and old versions of Windows NT like 3.51 and 4.0. The previous version of the app only went as far back as Windows XP.

The app spits out benchmarking scores for five things: single-core CPU performance, multi-core CPU performance, 2D graphics performance using GDI, 3D graphics performance using OpenGL, and disk speed (broken into four sub-benchmarks for sequential and random read and write performance).

The app will also run on current systems, including 64-bit x86 and Arm-based PCs, and the results database is dominated by those modern systems. But searching by operating system allows you to zero in on those retro results, including nine (as of this writing) for Windows 95, six for Windows 98, and five for Windows NT 3.51.

When BMW introduced the original M5 to the European motoring public in 1984, the automaker effectively established a new vehicle segment. By combining the practical and understatedly rakish E28 5-Series with the motorsport-derived six-cylinder engine from the M1 supercar, the automaker had created a “do-it-all” performance machine, a vehicle that could serve as a tasteful and luxurious sedan one moment and a charismatic sports car the next.

It’s a concept that has guided the development of not only subsequent generations of the M5 but also all of the other sports sedans that have dared to go toe to toe with it over the past forty years. For decades, it’s been the benchmark by which all big, fast four-doors have been judged, but after spending a week with the all-new $125,275 G99-generation M5 Touring, I can’t help but wonder if that era is coming to a close.

A range of factors have contributed to this seismic shift. While other automakers have been chasing the M5’s ghost around the Nürburgring, BMW has purposely started to reposition its M Division vehicles as the pinnacle representation of the brand rather than the pinnacle representation of BMW performance. It’s a move that has yielded models like the XM, a vehicle that certainly has plenty of firepower under the hood but ultimately prioritizes style over substance.

Google released its latest and greatest Gemini AI model last week, but it was only made available to paying subscribers. Google has moved with uncharacteristic speed to release Gemini 2.5 Pro (Experimental) for free users, too. The next time you check in with Gemini, you can access most of the new AI's features without a Gemini Advanced subscription.

The Gemini 2.5 branch will eventually replace 2.0, which was only released in late 2024. It supports simulated reasoning, as all Google's models will in the future. This approach to producing an output can avoid some of the common mistakes that AI models have made in the past. We've also been impressed with Gemini 2.5's vibe, which has landed it at the top of the LMSYS Chatbot arena leaderboard.

Google says Gemini 2.5 Pro (Experimental) is ready and waiting for free users to try on the web. Simply select the model from the drop-down menu and enter your prompt to watch the "thinking" happen. The model will roll out to the mobile app for free users soon.

Oh, ExoMars, what a long, strange trip it has been. Are you ever going to go to space?

The ExoMars mission represents Europe's third attempt to land successfully on Mars, and at a cost of more than $1.3 billion. there is a lot riding on its success. But success is far from assured for a mission that has been whipsawed by geopolitical tensions, budget cuts, and an ever-changing architecture over the last 20 years.

The latest news, announced Sunday, is that Airbus will design and build the lander that will carry the ExoMars down to the surface of Mars. The mission is scheduled to launch no earlier than 2028 on a US rocket. But there have been so many twists and turns in the ExoMars story that it's very difficult to know what will ultimately happen.

The first flight of Isar Aerospace's Spectrum rocket didn't last long on Sunday. The booster's nine engines switched off as the rocket cartwheeled upside-down and fell a short distance from its Arctic launch pad in Norway, punctuating the abbreviated test flight with a spectacular fiery crash into the sea.

If officials at Isar Aerospace were able to pick the outcome of their first test flight, it wouldn't be this. However, the result has precedent. The first launch of SpaceX's Falcon 1 rocket in 2006 ended in similar fashion.

"Today, we know twice as much about our launch system as yesterday before launch," Daniel Metzler, Isar's co-founder and CEO, wrote on X early Monday. "Can't beat flight testing. Ploughing through lots of data now."

Big brands are allocating small amounts of their advertising budget to Elon Musk’s X, seeking to avoid being seen as boycotting the social media platform and triggering a public fallout with its billionaire owner.

Multiple marketing executives told the Financial Times that companies have felt pressure to spend a nominal sum on X following Musk’s high-profile role in US President Donald Trump’s administration.

They said Musk’s pursuit of legal action against groups that have stopped advertising since his $44 billion acquisition in late 2022 had also sparked alarm. X last month added about half a dozen more companies to its case including Shell, Nestlé, Pinterest, and Lego.

Late last week, President Donald Trump decided to upend the automotive industry by levying a new 25 percent import tariff on all imported cars, which goes into effect on April 2. An additional 25 percent tariff on car parts is set to go into effect within the next month, which promises to make US-made cars more expensive as well, as many parts and subassemblies used in domestic manufacturing come from suppliers in Canada or Mexico.

During the election campaign (and in the years preceding it), Trump repeatedly claimed that the cost of tariffs would be borne by the exporters. But tariffs don't work that way—they're paid by the importer, at the time of import.

The White House does not appear to have any concerns about this, despite a report in The Wall Street Journal last week claiming that Trump had warned automakers not to pass the costs on to their customers.

QLED TV manufacturers have dug themselves into a hole.

After years of companies promising that their quantum dot light-emitting diode TVs use quantum dots (QDs) to boost color, some industry watchers and consumers have recently started questioning whether QLED TVs use QDs at all. Lawsuits have been filed, accusing companies like TCL of using misleading language about whether their QLED TVs actually use QDs.

In this article, we'll break down why new conspiracy theories about QLED TVs are probably overblown. We'll also explore why misleading marketing from TV brands is responsible for customer doubt and how it all sets a bad precedent for the future of high-end displays, including OLED TVs and monitors.

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer, Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles here, here, and here.

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The discovery is one of the most significant findings in the search for evidence of past life on Mars. This is because, on Earth at least, relatively complex, long-chain carbon molecules are involved in biology. These molecules could actually be fragments of fatty acids, which are found in, for example, the membranes surrounding biological cells.

Scientists think that, if life ever emerged on Mars, it was probably microbial in nature. Because microbes are so small, it’s difficult to be definitive about any potential evidence for life found on Mars. Such evidence needs more powerful scientific instruments that are too large to be put on a rover.

The organic molecules found by Curiosity consist of carbon atoms linked in long chains, with other elements bonded to them, like hydrogen and oxygen. They come from a 3.7-billion-year-old rock dubbed Cumberland, encountered by the rover at a presumed dried-up lakebed in Mars’ Gale Crater. Scientists used the Sample Analysis at Mars (SAM) instrument on the NASA rover to make their discovery.

The so-called Department of Government Efficiency (DOGE) is starting to put together a team to migrate the Social Security Administration’s (SSA) computer systems entirely off one of its oldest programming languages in a matter of months, potentially putting the integrity of the system—and the benefits on which tens of millions of Americans rely—at risk.

The project is being organized by Elon Musk lieutenant Steve Davis, multiple sources who were not given permission to talk to the media tell WIRED, and aims to migrate all SSA systems off COBOL, one of the first common business-oriented programming languages, and onto a more modern replacement like Java within a scheduled tight timeframe of a few months.

Under any circumstances, a migration of this size and scale would be a massive undertaking, experts tell WIRED, but the expedited deadline runs the risk of obstructing payments to the more than 65 million people in the US currently receiving Social Security benefits.

ProPublica is a Pulitzer Prize-winning investigative newsroom. Sign up for The Big Story newsletter to receive stories like this one in your inbox.

Leaders at the Centers for Disease Control and Prevention ordered staff this week not to release their experts’ assessment that found the risk of catching measles is high in areas near outbreaks where vaccination rates are lagging, according to internal records reviewed by ProPublica.

In an aborted plan to roll out the news, the agency would have emphasized the importance of vaccinating people against the highly contagious and potentially deadly disease that has spread to 19 states, the records show.

A CDC spokesperson told ProPublica in a written statement that the agency decided against releasing the assessment “because it does not say anything that the public doesn’t already know.” She added that the CDC continues to recommend vaccines as “the best way to protect against measles.”

But what the nation’s top public health agency said next shows a shift in its long-standing messaging about vaccines, a sign that it may be falling in line under Health and Human Services Secretary Robert F. Kennedy Jr., a longtime critic of vaccines:

“The decision to vaccinate is a personal one,” the statement said, echoing a line from a column Kennedy wrote for the Fox News website. “People should consult with their healthcare provider to understand their options to get a vaccine and should be informed about the potential risks and benefits associated with vaccines.”

ProPublica shared the new CDC statement about personal choice and risk with Jennifer Nuzzo, director of the Pandemic Center at Brown University School of Public Health. To her, the shift in messaging, and the squelching of this routine announcement, is alarming.

“I’m a bit stunned by that language,” Nuzzo said. “No vaccine is without risk, but that makes it sound like it’s a very active coin toss of a decision. We’ve already had more cases of measles in 2025 than we had in 2024, and it’s spread to multiple states. It is not a coin toss at this point.”

For many years, the CDC hasn’t minced words on vaccines. It promoted them with confidence. One campaign was called “Get My Flu Shot.” The agency’s website told medical providers they play a critical role in helping parents choose vaccines for their children: “Instead of saying ‘What do you want to do about shots?,’ say ‘Your child needs three shots today.’”

Nuzzo wishes the CDC’s forecasters would put out more details of their data and evidence on the spread of measles, not less. “The growing scale and severity of this measles outbreak and the urgent need for more data to guide the response underscores why we need a fully staffed and functional CDC and more resources for state and local health departments,” she said.

Kennedy’s agency oversees the CDC and on Thursday announced it was poised to eliminate 2,400 jobs there.

When asked what role, if any, Kennedy played in the decision to not release the risk assessment, HHS’s communications director said the aborted announcement “was part of an ongoing process to improve communication processes—nothing more, nothing less.” The CDC, he reiterated, continues to recommend vaccination “as the best way to protect against measles.”

“Secretary Kennedy believes that the decision to vaccinate is a personal one and that people should consult with their healthcare provider to understand their options to get a vaccine,” Andrew G. Nixon said. “It is important that the American people have radical transparency and be informed to make personal healthcare decisions.”

Responding to questions about criticism of the decision among some CDC staff, Nixon wrote, “Some individuals at the CDC seem more interested in protecting their own status or agenda rather than aligning with this Administration and the true mission of public health.”

The CDC’s risk assessment was carried out by its Center for Forecasting and Outbreak Analytics, which relied, in part, on new disease data from the outbreak in Texas. The CDC created the center to address a major shortcoming laid bare during the COVID-19 pandemic. It functions like a National Weather Service for infectious diseases, harnessing data and expertise to predict the course of outbreaks like a meteorologist warns of storms.

Other risk assessments by the center have been posted by the CDC even though their conclusions might seem obvious.

In late February, for example, forecasters analyzing the spread of H5N1 bird flu said people who come “in contact with potentially infected animals or contaminated surfaces or fluids” faced a moderate to high risk of contracting the disease. The risk to the general US population, they said, was low.

In the case of the measles assessment, modelers at the center determined the risk of the disease for the general public in the US is low, but they found the risk is high in communities with low vaccination rates that are near outbreaks or share close social ties to those areas with outbreaks. The CDC had moderate confidence in the assessment, according to an internal Q&A that explained the findings. The agency, it said, lacks detailed data about the onset of the illness for all patients in West Texas and is still learning about the vaccination rates in affected communities as well as travel and social contact among those infected. (The H5N1 assessment was also made with moderate confidence.)

The internal plan to roll out the news of the forecast called for the expert physician who’s leading the CDC’s response to measles to be the chief spokesperson answering questions. “It is important to note that at local levels, vaccine coverage rates may vary considerably, and pockets of unvaccinated people can exist even in areas with high vaccination coverage overall,” the plan said. “The best way to protect against measles is to get the measles, mumps, and rubella (MMR) vaccine.”

This week, though, as the number of confirmed cases rose to 483, more than 30 agency staff were told in an email that after a discussion in the CDC director’s office, “leadership does not want to pursue putting this on the website.”

The cancellation was “not normal at all,” said a CDC staff member who spoke anonymously for fear of reprisal with layoffs looming. “I’ve never seen a rollout plan that was canceled at that far along in the process.”

Anxiety among CDC staff has been building over whether the agency will bend its public health messages to match those of Kennedy, a lawyer who founded an anti-vaccine group and referred clients to a law firm suing a vaccine manufacturer.

During Kennedy’s first week on the job, HHS halted the CDC campaign that encouraged people to get flu shots during a ferocious flu season. On the night that the Trump administration began firing probationary employees across the federal government, some key CDC flu webpages were taken down. Remnants of some of the campaign webpages were restored after NPR reported this.

But some at the agency felt like the new leadership had sent a message loud and clear: When next to nobody was paying attention, long-standing public health messages could be silenced.

On the day in February that the world learned that an unvaccinated child had died of measles in Texas, the first such death in the U.S. since 2015, the HHS secretary downplayed the seriousness of the outbreak. “We have measles outbreaks every year,” he said at a cabinet meeting with President Donald Trump.

In an interview on Fox News this month, Kennedy championed doctors in Texas who he said were treating measles with a steroid, an antibiotic and cod liver oil, a supplement that is high in vitamin A. “They’re seeing what they describe as almost miraculous and instantaneous recovery from that,” Kennedy said.

As parents near the outbreak in Texas stocked up on vitamin A supplements, doctors there raced to assure parents that only vaccination, not the vitamin, can prevent measles.

Still, the CDC added an entry on Vitamin A to its measles website for clinicians.

On Wednesday, CNN reported that several hospitalized children in Lubbock, Texas, had abnormal liver function, a likely sign of toxicity from too much vitamin A.

Texas health officials also said that the Trump administration’s decision to rescind $11 billion in pandemic-related grants across the country will hinder their ability to respond to the growing outbreak, according to The Texas Tribune.

Measles is among the most contagious diseases and can be dangerous. About 20 percent of unvaccinated people who get measles wind up in the hospital. And nearly 1 to 3 of every 1,000 children with measles will die from respiratory and neurologic complications. The virus can linger in the air for two hours after an infected person has left an area, and patients can spread measles before they even know they have it.

This week Amtrak said it was notifying customers that they may have been exposed to the disease this month when a passenger with measles rode one of its trains from New York City to Washington, DC.

Microsoft released a new Windows Insider build of Windows 11 to its experimental Dev Channel today, with a fairly extensive batch of new features and tweaks. But the most important one for enthusiasts and PC administrators is buried halfway down the list: This build removes a command prompt script called bypassnro, which up until now has been a relatively easy and reliable way to circumvent the otherwise mandatory Microsoft Account sign-in requirement on new Windows 11 PCs and fresh installs of Windows 11 on existing PCs.

Microsoft's Windows Insider Program lead Amanda Langowski and Principal Product Manager Brandon LeBlanc were clear that this change is considered a feature and not a bug.

"We’re removing the bypassnro.cmd script from the build to enhance security and user experience of Windows 11," Langowski and LeBlanc write in the post. "This change ensures that all users exit setup with internet connectivity and a Microsoft Account."

One of the most frustrating things about using a large language model is dealing with its tendency to confabulate information, hallucinating answers that are not supported by its training data. From a human perspective, it can be hard to understand why these models don't simply say "I don't know" instead of making up some plausible-sounding nonsense.

Now, new research from Anthropic is exposing at least some of the inner neural network "circuitry" that helps an LLM decide when to take a stab at a (perhaps hallucinated) response versus when to refuse an answer in the first place. While human understanding of this internal LLM "decision" process is still rough, this kind of research could lead to better overall solutions for the AI confabulation problem.

In a groundbreaking paper last May, Anthropic used a system of sparse auto-encoders to help illuminate the groups of artificial neurons that are activated when the Claude LLM encounters internal concepts ranging from "Golden Gate Bridge" to "programming errors" (Anthropic calls these groupings "features," as we will in the remainder of this piece). Anthropic's newly published research this week expands on that previous work by tracing how these features can affect other neuron groups that represent computational decision "circuits" Claude follows in crafting its response.

Imagine working with special cameras that capture light your eyes can't even see—ultraviolet rays that cause sunburn or infrared heat signatures that reveal hidden writing. Or perhaps using specialized cameras sensitive enough to distinguish subtle color variations in paint that look just right under specific lighting. Scientists and engineers do this every day—and the resulting data files are so large, they're drowning in it.

A new compression format called Spectral JPEG XL might finally solve this growing problem in scientific visualization and computer graphics. Researchers Alban Fichet and Christoph Peters of Intel Corporation detailed the format in a recent paper published in the Journal of Computer Graphics Techniques (JCGT). It tackles a serious bottleneck for industries working with these specialized images. These spectral files can contain 30, 100, or more data points per pixel, causing file sizes to balloon into multi-gigabyte territory—making them unwieldy to store and analyze.

When we think of digital images, we typically imagine files that store just three colors: red, green, and blue (RGB). This works well for everyday photos, but capturing the true color and behavior of light requires much more detail. Spectral images aim for this higher fidelity by recording light's intensity not just in broad RGB categories, but across dozens or even hundreds of narrow, specific wavelength bands. This detailed information primarily spans the visible spectrum and often extends into near-infrared and near-ultraviolet regions crucial for simulating how materials interact with light accurately.

Since Trump took office on January 20, research funding from the National Institutes of Health has plummeted by more than $3 billion compared with the pace of funding in 2024, according to an analysis by The Washington Post.

By this time in March 2024, the NIH had awarded US researchers a total of $1.027 billion for new grants or competitive grant renewals. This year, the figure currently stands at about $400 million. Likewise, funding for renewals of existing grants without competition reached $4.5 billion by this time last year, but has only hit $2 billion this year. Together, this slowdown amounts to a 60 percent drop in grant support for a wide variety of research—from studies on cancer treatments, diabetes, and Alzheimer's to vaccines, mental health, transgender health, and more.

The NIH is the primary source of funding for biomedical research in the US. NIH grants support more than 300,000 scientists at more than 2,500 universities, medical schools, and other research organizations across all 50 states.

Oracle isn’t commenting on recent reports that it has experienced two separate data breaches that have exposed sensitive personal information belonging to thousands of its customers.

The most recent data breach report, published Friday by Bleeping Computer, said that Oracle Health—a health care software-as-a-service business the company acquired in 2022—had learned in February that a threat actor accessed one of its servers and made off with patient data from US hospitals. Bleeping Computer said Oracle Health customers have received breach notifications that were printed on plain paper rather than official Oracle letterhead and were signed by Seema Verma, the executive vice president & GM of Oracle Health.

The other report of a data breach occurred eight days ago, when an anonymous person using the handle rose87168 published a sampling of what they said were 6 million records of authentication data belonging to Oracle Cloud customers. Rose87168 told Bleeping Computer that they had acquired the data a little more than a month earlier after exploiting a vulnerability that gave access to an Oracle Cloud server.

Google acquired Nest in 2014 for a whopping $3.4 billion but seems increasingly uninterested in making smart home hardware. The company has just announced two of its home gadgets will be discontinued, one of which is quite popular. The Nest Protect smoke and carbon monoxide detector is a common fixture in homes, but Google says it has stopped manufacturing it. The less popular Nest x Yale smart lock is also getting the ax. There are replacements coming, but Google won't be making them.

Nest launched the 2nd gen Protect a year before it became part of Google. Like all smoke detectors, the Nest Protect comes with an expiration date. You're supposed to swap them out every 10 years, so some Nest users are already there. You will have to hurry if you want a new Protect. While they're in stock for the moment, Google won't manufacture any more. It's on sale for $119 on the Google Store for the time being.

Likewise, Google is done with the Nest x Yale smart lock, which it launched in 2018 to complement the Nest Secure home security system. This device requires a Thread-enabled hub, a role the Nest Secure served quite well. Now, you need a $70 Nest Connect to control this lock remotely. If you still want to grab the Nest x Yale smart lock, it's on sale for $229 while supplies last.
