                            <![CDATA[<p>A Rome court has ruled that the price hikes Netflix imposed on subscribers in Italy in 2017, 2019, 2021, and 2024 were unlawful. The court ordered Netflix to refund affected customers by up to €500 (about $576), depending on their plan.</p>
<p>The lawsuit was brought by Italian consumer advocacy group Movimento Consumatori, which alleged that the price hikes violate the Consumer Code, Italian legislation that aims to protect consumer rights. The Consumer Code <a href="https://www.normattiva.it/esporta/attoCompleto?atto.dataPubblicazioneGazzetta=2005-10-08&amp;atto.codiceRedazionale=005G0232">says</a> it's unlawful for a “professional to unilaterally modify the clauses of the contract, or the characteristics of the product or service to be provided, without a justified reason indicated in the contract itself,” according to a Google-provided translation.</p>
<p>The court’s April 1 ruling determined that Netflix's contracts were required to explain in advance why prices or other terms might change in the future.</p><p><a href="https://arstechnica.com/gadgets/2026/04/netflix-ordered-to-refund-subscribers-up-to-e500-for-unlawful-price-hikes/">Read full article</a></p>

                            <![CDATA[<p>With the war in the Persian Gulf now more than a month old, the effect on fuel prices is plain to see: On average, they're up almost a dollar per gallon, or 25 percent, <a href="https://gasprices.aaa.com">according to AAA</a>. For a nation as addicted to the automotive as we are, that's bad news. Except, of course, for electric vehicles.</p>
<p>The last half year has been rough for EV adoption here in the US. At the end of last September, the Trump administration abolished the federal tax credit for both new and used EVs, one of a series of policies that has disincentivized automakers to build EVs and consumers to buy them. Battery factories have been cancelled or <a href="https://arstechnica.com/cars/2025/12/ford-ends-f-150-lightning-production-starts-battery-storage-business/">repurposed</a>, and EV lineups have <a href="https://arstechnica.com/cars/2026/03/facing-heavy-losses-honda-cancels-its-three-us-made-electric-vehicles/">been slashed</a> as OEMs <a href="https://arstechnica.com/cars/2026/01/fewer-american-evs-costs-gm-6-billion-even-as-its-chinese-sales-boom/">write down</a> billions of dollars in the process.</p>
<p>Some analysts have predicted a particularly grim Q1 2026. Cox Automotive, for example, forecast a 6.5 percent overall decrease in new car sales for the first three months of the year but a 28 percent decrease in EV sales for the same period. Without sustained high fuel prices, Stephanie Valdez Streaty, Cox's director of industry insights, expects people to make fewer trips. "To materially change buying behavior and drive a trend toward smaller, more efficient vehicles, consumers would need to believe gas prices will remain elevated for years, not just months," <a href="https://www.cnn.com/2026/03/26/business/4-dollar-gas-impact-on-ev-sales">Cox said</a>.</p><p><a href="https://arstechnica.com/cars/2026/04/ev-adoption-in-america-whos-winning-whos-losing/">Read full article</a></p>

For NASA and the Artemis II crew members, this marked a point of no return for more than a week.</p>
<p>About three-quarters of the American population has not witnessed humans leaving low-Earth orbit in their lifetimes. The last time this occurred was 1972, with the final Apollo Moon mission.</p>
<p>The “translunar injection” burn of Orion’s main engine occurred about one day after the successful launch of the mission on NASA’s Space Launch System rocket from Kennedy Space Center on Wednesday. This burn was the last major firing of Orion’s main engine and sets the crew on a course to fly around the Moon on Monday, slingshot back toward Earth under lunar gravity, and splash down in the Pacific Ocean on Friday, April 10.</p><p><a href="https://arstechnica.com/space/2026/04/four-astronauts-are-now-inexorably-bound-for-the-moon/">Read full article</a></p>

<p>"This happened to every user regardless of whether or not they signed up for a Perplexity account," the lawsuit alleged, while stressing that "enormous volumes of sensitive information from both subscribed and non-subscribed users" are shared.</p>
<p>Using developer tools, the lawsuit found that opening prompts are always shared, as are any follow-up questions the search engine asks that a user clicks on. Privacy concerns are seemingly worse for non-subscribed users, the complaint alleged. Their initial prompts are shared with "a URL through which the entire conversation may be accessed by third parties like Meta and Google."</p><p><a href="https://arstechnica.com/tech-policy/2026/04/perplexitys-incognito-mode-is-a-sham-lawsuit-says/">Read full article</a></p>

                            <![CDATA[<p>Starlink operator SpaceX claims that Amazon violated orbital debris requirements by launching satellites into initial altitudes that are too high, increasing the risk of collision with other satellites and spacecraft. SpaceX, which recently <a href="https://arstechnica.com/tech-policy/2026/03/starlink-satellite-breaks-apart-into-tens-of-objects-spacex-confirms-anomaly/">reported two Starlink satellite failures</a> that created new space debris, yesterday accused Amazon and its launch partner Arianespace of negligence that "needlessly and significantly increases risk to other operational systems and inhabited spacecraft."</p>
<p>Amazon Leo, formerly known as Kuiper Systems, is launching satellites into low-Earth orbits (LEO) to compete against Starlink's much larger constellation of broadband satellites. Amazon denied that its launch altitudes violate any requirements or impose a safety risk and said SpaceX itself helped Amazon launch satellites into a similar altitude last year when Amazon used SpaceX as a launch partner.</p>
<p>SpaceX only objected to the launch parameters after moving its Starlink satellites into nearby altitudes, Amazon said. Changing the altitude of a recent Leo launch would have delayed it by months, according to Amazon. Both Amazon and SpaceX have accused each other of using Federal Communications Commission proceedings to <a href="https://arstechnica.com/tech-policy/2021/09/amazon-slams-spacex-tells-fcc-that-musk-led-companies-are-rule-breakers/">delay the other's satellite launches</a> at various times over the years.</p><p><a href="https://arstechnica.com/tech-policy/2026/04/spacex-claims-amazon-leo-launches-could-crash-into-starlink-satellites/">Read full article</a></p>

                            <![CDATA[<p>OpenAI might be <a href="https://arstechnica.com/ai/2026/03/openai-plans-to-shut-down-sora-just-15-months-after-its-launch/">pulling back</a> on video generation, but Google is forging ahead with a <a href="https://blog.google/products-and-platforms/products/workspace/google-vids-updates-lyria-veo/">major AI update</a> to its Vids editing product. The company's latest video and audio models are now integrated with the tool, and you can choose from various controllable avatars to appear in generated videos. Your creations are also easier to share on YouTube now.</p>
<p>Veo 3.1 is the biggest part of the Vids upgrade. Google first deployed this updated model in Gemini <a href="https://arstechnica.com/google/2025/10/googles-ai-videos-get-a-big-upgrade-with-veo-3-1/">late last year</a>, promising a substantial improvement in realism and consistency. While Google has pitched Veo as a tool for filmmakers, that's not how it positions Vids. Google suggests using the AI tools in Vids to create animated party flyers, business sizzle reels, or a video greeting card. You can use Vids for free, but you won't be able to generate very many videos without an AI subscription.</p>

<p>If you're not paying for any AI access on your account, you only get 10 video generations per month. AI Pro subscribers can get 50 videos, and those paying for Google's spendy AI Ultra plan (either personal or enterprise) get 1,000 videos per month. Like most other Veo implementations, the videos are eight seconds long and 720p resolution.</p><p><a href="https://arstechnica.com/ai/2026/04/google-vids-gets-ai-upgrade-with-veo-and-lyria-models-directable-ai-avatars/">Read full article</a></p>

                            <![CDATA[<p>Octopuses are one of the most alien creatures on Earth. The lack of bones makes them amazing shapeshifters, most of them can change color like chameleons, and they pump blue copper-based blood through their bodies using three distinct hearts. They rely on a decentralized nervous system, where two-thirds of their neurons reside in their arms, allowing each limb to independently taste, touch, and make decisions for itself.</p>
<p>Now, a team of scientists led by Pablo S. Villar, a molecular biologist at Harvard University, for the first time took a close look at octopuses' sex life. It turned out it was just as weird.</p>
<h2>Love in the dark</h2>
<p>The deep ocean is a challenging place to find a partner, especially since octopuses are solitary animals that wander the seafloor alone, mating only during highly infrequent encounters. The exact mechanics of their reproduction when they do find each other have long puzzled biologists. We knew that male octopuses don't rely on flashy plumage or complex mating calls and that they use a specialized appendage called the hectocotylus—basically a modified tentacle—to identify females.</p><p><a href="https://arstechnica.com/science/2026/04/male-octopuses-guided-through-mating-by-female-hormones/">Read full article</a></p>

                            <![CDATA[<p>The details of how animal life began are a bit murky. Most of the groups familiar today are present in the Cambrian, a period when they rapidly diversified, with familiar features evolving alongside bizarre creatures with no obvious modern equivalents. There are hints that some forms of present animal life predated the Cambrian. But most of the organisms we've found in Ediacaran deposits have no obvious relationship to anything we're familiar with.</p>
<p>The complete absence of these creatures in later strata suggests they might have vanished in <a href="https://en.wikipedia.org/wiki/End-Ediacaran_extinction">a mass-extinction event</a> that cleared the way for the explosion of Cambrian species. But a new series of fossils found at a site in China includes examples of groups that flourished in the Cambrian living side by side with a few Ediacaran species. The deposits suggest that there might have been a gradual shift into the Cambrian.</p>
<h2>Ediacaran and more</h2>
<p>The newly described fossils, described by a team from Yunnan University and Oxford University, come from just south of Kunming, near Fuxian Lake. The rocks they're in are part of the larger Dengying Formation, within a segment known to include Edicaran deposits, which ranged from 635 to 540 million years ago. They come from close to the end of the period, only about 7 million years before the first clearly Cambrian deposits.</p><p><a href="https://arstechnica.com/science/2026/04/new-fossil-deposits-show-complex-animal-groups-predating-the-cambrian/">Read full article</a></p>

                            <![CDATA[<p>The cost of high-performance GPUs, typically $8,000 or more, means they are frequently shared among dozens of users in cloud environments. Three new attacks demonstrate how a malicious user can gain full root control of a host machine by performing novel Rowhammer attacks on high-performance GPU cards made by Nvidia.</p>
<p>The attacks exploit memory hardware’s increasing susceptibility to bit flips, in which 0s stored in memory switch to 1s and vice versa. In <a href="https://users.ece.cmu.edu/~yoonguk/papers/kim-isca14.pdf">2014</a>, researchers first demonstrated that repeated, rapid access—or “hammering”—of memory hardware known as <a href="https://en.wikipedia.org/wiki/Dynamic_random-access_memory">DRAM</a> creates electrical disturbances that flip bits. A <a href="https://arstechnica.com/information-technology/2015/03/cutting-edge-hack-gives-super-user-status-by-exploiting-dram-weakness/">year later</a>, a different research team showed that by targeting specific DRAM rows storing sensitive data, an attacker could exploit the phenomenon to escalate an unprivileged user to root or evade security sandbox protections. Both attacks targeted DDR3 generations of DRAM.</p>

                            <![CDATA[<p>On Wednesday, the International Renewable Energy Agency (IRENA) released its numbers on what was built in 2025. And much as <a href="https://arstechnica.com/science/2026/02/final-2025-data-is-in-us-energy-use-is-up-as-solar-passes-hydro/">we saw in the US</a>, solar power is the primary driver of change. The numbers show that the world installed an average of 1.4 gigawatts of solar capacity every day last year, for a total of 511 GW. That brings the total solar capacity up to 2.4 Terawatts, making it the largest single source of renewable capacity by far, at more than a Terawatt above either wind or hydro.</p>
<p>Obviously, the actual power generated will be less than the rated capacity. And because solar panels have become so cheap, the economics now favor installing panels in areas that get far less sunlight—places in which photovoltaics would have been a questionable decision just five years earlier. So we're likely to see the energy produced for each unit of capacity (termed the capacity factor) decline over the coming years.</p>
<p>How much of a factor is that? 2025's power-generation numbers are not yet available, but <a href="https://www.iea.org/data-and-statistics/charts/global-electricity-generation-by-source-2024">data from 2024</a> shows photovoltaics generating 7 percent of the world's power, with wind at 8 percent and nuclear at 9. That's despite having 1.9 times as much solar capacity as wind capacity. Still, despite the lower capacity factor, solar is catching up fast. As these numbers don't include concentrated solar power or last year's data, it's possible that solar has already become the second-largest source of carbon-free electricity (after hydropower). If not, we're certain to see that happen before the decade is out.</p><p><a href="https://arstechnica.com/science/2026/04/globally-86-percent-of-the-new-generating-capacity-was-renewable-in-2025/">Read full article</a></p>

                    </description>
                                                                <content:encoded>
                            <![CDATA[<p>Google's Gemini AI models have improved by leaps and bounds over the past year, but you can only use Gemini on Google's terms. The company's Gemma open-weight models have provided more freedom, but Gemma 3, which launched <a href="https://arstechnica.com/gadgets/2025/03/googles-new-gemma-3-ai-model-is-optimized-to-run-on-a-single-gpu/">over a year ago</a>, is getting a bit long in the tooth. Starting today, developers can start working with <a href="https://blog.google/innovation-and-ai/technology/developers-tools/gemma-4/">Gemma 4</a>, which comes in four sizes optimized for local usage. Google has also acknowledged developer frustrations with AI licensing, so it's dumping the custom Gemma license.</p>
<p>Like past versions of its open-weight models, Google has designed Gemma 4 to be usable on local machines. That can mean plenty of things, of course. The two large Gemma variants, 26B Mixture of Experts and 31B Dense, are designed to run unquantized in bfloat16 format on a single 80GB Nvidia H100 GPU. Granted, that's a $20,000 AI accelerator, but it's still local hardware. If quantized to run at lower precision, these big models will fit on consumer GPUs.</p>
<p>Google also claims it has focused on reducing latency to really take advantage of Gemma's local processing. The 26B Mixture of Experts model activates only 3.8 billion of its 26 billion parameters in inference mode, giving it much higher tokens-per-second than similarly sized models. Meanwhile, 31B Dense is more about quality than speed, but Google expects developers to fine-tune it for specific uses.</p><p><a href="https://arstechnica.com/ai/2026/04/google-announces-gemma-4-open-ai-models-switches-to-apache-2-0-license/">Read full article</a></p>

                            <![CDATA[<p>When it comes to automotive bragging rights, a good Nürburgring Nordschleife lap time is right up there with the best of them. And today, those bragging rights belong to Ford. The automaker revealed that its GT Mk IV, an evolution of the mid-engined supercar it created in 2016, is now the fastest production car to ever lap the 12.9-mile (20.8-km) race track in Germany, with a time of 6 minutes, 15.997 seconds set by Frédéric Vervisch.</p>
<p>The century-old racetrack in Germany's Eifel region was built during the Great Depression as a way to create jobs but also to provide Germany's car industry with a place to test its products. In addition to races, it was—and remains—open to the public for leisure driving.</p>
<p>Well, for some definition of leisure: The place isn't known as the Green Hell for nothing, with hundreds of feet of elevation change across 12.9 miles (20.8 km) and between 73–170 corners, depending how you count them. After years of driving it online, I got my first laps there last summer and can report that in real life, it is bumpy and narrow, and I'd need another hundred laps or so before I started to feel properly comfortable.</p><p><a href="https://arstechnica.com/cars/2026/04/a-production-ford-sets-third-fastest-time-ever-at-the-nurburgring/">Read full article</a></p>

                            <![CDATA[<p>An Anthropic-backed DMCA effort to remove its <a href="https://arstechnica.com/ai/2026/03/entire-claude-code-cli-source-code-leaks-thanks-to-exposed-map-file/">recently leaked Claude Code client source code</a> from GitHub this week resulted in the accidental removal of many legitimate forks of its official public code repository. While that overzealous takedown has now been reversed, Anthropic still faces an extreme uphill battle in limiting the spread of its recently leaked code.</p>
<p><a href="https://github.com/github/dmca/blob/master/2026/03/2026-03-31-anthropic.md">The DMCA notice</a> that GitHub received late Tuesday focuses on a repository containing the leaked source code originally posted by GitHub user nirholas (<a href="https://web.archive.org/web/20260331130836/https://github.com/nirholas/claude-code">archived here</a>) and nearly 100 specifically named forks of that repository. In a note appended to that request, though, GitHub said it had acted to take down a network of 8,100 similar forked repositories because "the submitter alleged that all or most of the forks were infringing to the same extent as the parent repository."</p>
<p>That expanded takedown <span style="box-sizing: border-box; margin: 0px; padding: 0px;">affected many repositories that didn't contain leaked code but instead forked <a href="https://github.com/anthropics/claude-code" target="_blank" rel="noopener">Anthropic's official public Claude Code repository</a>, which the company shares to encourage public bug reports and fixes</span>. Many coders <a href="https://x.com/robertmclaws/status/2039129333428871463">took</a> <a href="https://x.com/yassersstudio/status/2039630328675930446">to</a> <a href="https://x.com/trq212/status/2039415036645679167">social</a> <a href="https://x.com/0xOzen/status/2039651302070792620">media</a> to complain about being swept up in the DMCA dragnet despite not sharing any leaked code.</p><p><a href="https://arstechnica.com/ai/2026/04/anthropic-says-its-leak-focused-dmca-effort-unintentionally-hit-legit-github-forks/">Read full article</a></p>

                        <![CDATA[Between January and March, Tesla built 50,000 more cars than it could sell.]]>
                    </description>

                            <![CDATA[<p>This morning, Tesla published its production and delivery results for the first three months of 2026. And for the first time <a href="https://arstechnica.com/cars/2026/01/2025-sees-teslas-annual-revenue-fall-for-the-first-time/">in a while</a>, the news has been largely positive. The automaker built a total of 408,386 electric vehicles, a 12.6 percent increase <a href="https://arstechnica.com/cars/2025/04/tesla-sales-and-production-slumped-heavily-in-q1-2025/">from Q1 2025</a>.</p>
<p>Almost all of those EVs were Models 3 and Y—the company built 394,611 of these, a 14.2 percent increase compared to the same quarter last year. The rest were mostly Cybertrucks, as we learned at the end of January that the aging Models S and X had <a href="https://arstechnica.com/cars/2026/01/tesla-kills-models-s-and-x-to-build-humanoid-robots-instead/">finally been put out to pasture</a>. At 14 years, the Model S's service to Tesla showed longevity beaten only by Nissan's R35 GT-R, which was old enough to vote when it was finally retired.</p>
<h2>Overproduction</h2>
<p>Tesla also recorded an increase in sales for Q1, though not to the same degree. It sold a total of 358,023 EVs, a 6.3 percent increase compared to the same quarter in 2025. Unfortunately for Tesla, that growth is only half as much as the increase in production.</p><p><a href="https://arstechnica.com/cars/2026/04/tesla-sales-grew-by-6-in-q1-but-company-has-an-overproduction-problem/">Read full article</a></p>

                            <![CDATA[<p>PC gamers who are tired of waiting for their games to "compile shaders" during some load times may want to dig into <a href="https://www.nvidia.com/en-us/geforce/news/nvidia-app-dlss-4-5-dynamic-multi-frame-generation-available-now/">the latest beta version of the Nvidia App</a>. Alongside new DLSS 4.5 Multi Frame Generation features, the app includes the beta rollout of a feature that allows your machine to automatically compile new shaders while it's idle.</p>
<p>Nvidia's new Auto Shader Compilation system promises to "reduc[e] the frequency of game runtime compilation after driver updates" for users running <a href="https://www.nvidia.com/en-us/drivers/details/265874/">Nvidia's GeForce Game Ready Driver 595.97 WHQL</a> or later. When the feature is active and your machine is idle, the app will automatically start rebuilding DirectX drivers for your games so they're all set to roll the next time they launch.</p>
<p>While the feature defaults to being turned off when the Nvidia App is first downloaded, users can activate it by going to the Graphics Tab &gt; Global Settings &gt; Shader Cache. There, they can set aside disk space for precompiled shaders and decide how many system resources the compilation process should use. App users can also manually force shader recompilation through the app rather than waiting for the machine to go idle.</p><p><a href="https://arstechnica.com/gaming/2026/04/nvidias-new-app-lets-you-precompile-gaming-shaders-during-machine-idle-time/">Read full article</a></p>

But observers digging through over 512,000 lines of code across more than 2,000 files have also discovered references to disabled, hidden, or inactive features that provide a peek into the potential roadmap for future features.</p>
<p>Chief among these features is <a href="https://github.com/zackautocracy/claude-code/blob/4b9d30f7953273e567a18eb819f4eddd45fcc877/src/memdir/memdir.ts#L319">Kairos</a>, a persistent daemon that can operate in the background even when the Claude Code terminal window is closed. The system would use periodic "&lt;tick&gt;" prompts to regularly review whether new actions are needed and <a href="https://github.com/zackautocracy/claude-code/blob/4b9d30f7953273e567a18eb819f4eddd45fcc877/src/tools/BriefTool/BriefTool.ts#L34">a "PROACTIVE" flag</a> for "surfacing something the user hasn't asked for and needs to see now."</p>
<p>Kairos makes use of a file-based "memory system" designed to allow for persistent operation across user sessions. <a href="https://github.com/zackautocracy/claude-code/blob/main/src/memdir/teamMemPrompts.ts">A prompt</a> hidden behind a disabled "KAIROS" flag in the code explains that the system is designed to "have a complete picture of who the user is, how they'd like to collaborate with you, what behaviors to avoid or repeat, and the context behind the work the user gives you."</p><p><a href="https://arstechnica.com/ai/2026/04/heres-what-that-claude-code-source-leak-reveals-about-anthropics-plans/">Read full article</a></p>
