Amid the brutal cuts across the federal government under the Trump administration, perhaps one of the most gutting is the loss of experts at the Centers for Disease Control and Prevention who respond to lead poisoning in children.

On April 1, the staff of the CDC's Childhood Lead Poisoning Prevention Program was terminated as part of the agency's reduction in force, according to NPR. The staff included epidemiologists, statisticians, and advisors who specialized in lead exposures and responses.

The cuts were immediately consequential to health officials in Milwaukee, who are currently dealing with a lead exposure crisis in public schools. Six schools have had to close, displacing 1,800 students. In April, the city requested help from the CDC's lead experts, but the request was denied—there was no one left to help.

In the US, many newly constructed generating facilities are brought online at the end of the year to qualify for tax incentives. Since much of the US's new generating capacity is solar power, that has led to a boom in solar production to start the year in recent years. With the first three months of data in for 2025, it's clear this year is no exception: Solar power is up a staggering 44 percent compared to the prior year.

That's the good news. The bad news is that, in contrast to China, solar's growth hasn't been enough to offset rising demand. Instead, the US also saw significant growth in coal use, which rose by 23 percent compared to the year prior, after years of steady decline.

Short-term fluctuations in demand are normal, generally driven by weather-induced demand for heating or cooling. Despite those changes, demand for electricity in the US has been largely flat for over a decade, largely thanks to gains in efficiency. But 2024 saw demand go up by nearly three percent, and the first quarter of 2025 saw another rise, this time of nearly five percent. It's a bit too early to say that we're seeing a shift to a period of rising demand, but one has been predicted for some time due to rising data center use and the increased electrification of transportation and appliances.

Valve is releasing version 3.7 of SteamOS to the general public, and among the routine updates and changes is a big one: This is the SteamOS release that finally adds official support for some kinds of PC hardware other than Valve's own Steam Deck.

Valve mentions certain specific handhelds as having either "official" or "improved support," including the Asus ROG Ally, the Lenovo Legion Go, and the Lenovo Legion Go S. It also includes directions for configuring the original Legion Go and ROG Ally for SteamOS installation. But Valve says that only the Steam Deck and Legion Go S have fully baked SteamOS support.

The release claims to run on "other AMD powered handhelds" more broadly, implying that most third-party handheld PCs with Ryzen Z1 or Z2-series processors ought to support at least some basic functionality. Other all-AMD desktops and laptops have a decent shot at being supported, too.

Expert advisors for the Food and Drug Administration met Thursday to discuss which virus strain this year's updated COVID-19 vaccines should target. The advisors have been meeting around this time each year for such a strain selection, a routine decision in the process of updating the life-saving vaccines.

But this year's meeting was awkward and even a little tense. Earlier this week, new FDA leaders under health secretary and anti-vaccine advocate Robert F. Kennedy Jr. announced a sweeping new framework that would restrict access to the shots, making them available only to people 65 and older and those with medical conditions that put them at risk of severe illness. For updated COVID-19 vaccines to be approved for healthy children and adults, vaccine makers would need to repeat large, randomized, placebo-controlled trials, which are expensive, ethically debatable at this point, and could easily take too much time to complete before the shots would need to be ready for fall vaccinations. The advisors weren't consulting on the new framework, and there is much uncertainty about its implementation.

Just thirty minutes into yesterday's nearly seven-hour meeting, one committee member broached one of the largest looming questions, saying, "If a different strain was selected for this season, would that require additional clinical trials, etc.?"

Donald Trump woke up Friday morning and threatened Apple with a 25 percent tariff on any iPhones sold in the US that are not manufactured in America.

In a Truth Social post, Trump claimed that he had "long ago" told Apple CEO Tim Cook that Apple's plan to manufacture iPhones for the US market in India was unacceptable. Only US-made iPhones should be sold here, he said.

"If that is not the case, a tariff of at least 25 percent must be paid by Apple to the US," Trump said.

Welcome to Edition 7.45 of the Rocket Report! Let's talk about spaceplanes. Since the Space Shuttle, spaceplanes have, at best, been a niche part of the space transportation business. The US Air Force's uncrewed X-37B and a similar vehicle operated by China's military are the only spaceplanes to reach orbit since the last shuttle flight in 2011, and both require a lift from a conventional rocket. Virgin Galactic's suborbital space tourism platform is also a spaceplane of sorts. A generation or two ago, one of the chief arguments in favor of spaceplanes was that they were easier to recover and reuse. Today, SpaceX routinely reuses capsules and rockets that look much more like conventional space vehicles than the winged designs of yesteryear. Spaceplanes are undeniably alluring in appearance, but they have the drawback of carrying extra weight (wings) into space that won't be used until the final minutes of a mission. So, do they have a future?

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

One of China's commercial rockets returns to flight. The Kinetica-1 rocket launched Wednesday for the first time since a failure doomed its previous attempt to reach orbit in December, according to the vehicle's developer and operator, CAS Space. The Kinetica-1 is one of several small Chinese solid-fueled launch vehicles managed by a commercial company, although with strict government oversight and support. CAS Space, a spinoff of the Chinese Academy of Sciences, said its Kinetica-1 rocket deployed multiple payloads with "excellent orbit insertion accuracy." This was the seventh flight of a Kinetica-1 rocket since its debut in 2022.

By late 2021, major updates for Windows' built-in Notepad text editor had been so rare for so long that a gentle redesign and a handful of new settings were rated as a major update. New updates have become much more common since then, but like the rest of Windows, recent additions have been overwhelmingly weighted in the direction of generative AI.

In November, Microsoft began testing an update that allowed users to rewrite or summarize text in Notepad using generative AI. Another preview update today takes it one step further, allowing you to write AI-generated text from scratch with basic instructions (the feature is called Write, to differentiate it from the earlier Rewrite).

Like Rewrite and Summarize, Write requires users to be signed into a Microsoft Account, because using it requires you to use your monthly allotment of Microsoft's AI credits. Per this support page, users without a paid Microsoft 365 subscription get 15 credits per month. Subscribers with Personal and Family subscriptions get 60 credits per month instead.

In recent written testimony to a US House of Representatives subcommittee that oversees the military, the senior official responsible for purchasing launches for national security missions blistered one of the country's two primary rocket providers.

The remarks from Major General Stephen G. Purdy, acting assistant secretary of the Air Force for Space Acquisition and Integration, concerned United Launch Alliance and its long-delayed development of the large Vulcan rocket.

"The ULA Vulcan program has performed unsatisfactorily this past year," Purdy said in written testimony during a May 14 hearing before the House Armed Services Committee's Subcommittee on Strategic Forces. This portion of his testimony did not come up during the hearing, and it has not been reported publicly to date.

Earlier this month, Nintendo received a lot of negative attention for an end-user license agreement (EULA) update granting the company the claimed right to render Switch consoles "permanently unusable in whole or in part" for violations such as suspected hacking or piracy. As it turns out, though, Nintendo isn't the only console manufacturer that threatens to remotely brick systems in response to rule violations. And attorneys tell Ars Technica that they're probably well within their legal rights to do so.

Sony's System Software License Agreement on the PS5, for instance, contains the following paragraph of "remedies" it can take for "violations" such as use of modified hardware or pirated software (emphasis added).

If SIE Inc determines that you have violated this Agreement's terms, SIE Inc may itself or may procure the taking of any action to protect its interests such as disabling access to or use of some or all System Software, disabling use of this PS5 system online or offline, termination of your access to PlayStation Network, denial of any warranty, repair or other services provided for your PS5 system, implementation of automatic or mandatory updates or devices intended to discontinue unauthorized use, or reliance on any other remedial efforts as reasonably necessary to prevent the use of modified or unpermitted use of System Software.

The same exact clause appears in the PlayStation 4 EULA as well. The PlayStation 3 EULA was missing the "disabling use... online or offline" clause, but it does still warn that Sony can take steps to "discontinue unauthorized use" or "prevent the use of a modified PS3 system, or any pirated material or equipment."

An outdated Meta AI model was apparently at the center of the Department of Government Efficiency's initial ploy to purge parts of the federal government.

Wired reviewed materials showing that affiliates of Elon Musk's DOGE working in the Office of Personnel Management "tested and used Meta’s Llama 2 model to review and classify responses from federal workers to the infamous 'Fork in the Road' email that was sent across the government in late January."

The "Fork in the Road" memo seemed to copy a memo that Musk sent to Twitter employees, giving federal workers the choice to be "loyal"—and accept the government's return-to-office policy—or else resign. At the time, it was rumored that DOGE was feeding government employee data into AI, and Wired confirmed that records indicate Llama 2 was used to sort through responses and see how many employees had resigned.

E-bike batteries are, for the most part, a collection of 18650 batteries, packaged together and welded in series and parallel, attached to a battery management system (BMS). A "dead" e-bike battery may only have two or three truly dead cells inside, while the remainder work fine. This is useful knowledge that, for the most part, very few e-bike owners can really use. Arc welders are not a common tool to own, and most e-bike batteries are not designed to be opened, safely or otherwise.

French firm Gouach, essentially a three-person company, is pitching its Infinite Battery as the opposite of this status quo. It's a durable, fireproof casing into which you can place and replace 18650 batteries using only a screwdriver. It keeps you updated on the status of cell performance and heat through a Bluetooth-connected app. And it's designed for compatibility with "90% of existing e-bike brands," or you can upgrade an existing "acoustic" model.

Researchers have found malicious software that received more than 6,000 downloads from the NPM repository over a two-year span, in yet another discovery showing the hidden threats users of such open source archives face.

Eight packages using names that closely mimicked those of widely used legitimate packages contained destructive payloads designed to corrupt or delete important data and crash systems, Kush Pandya, a researcher at security firm Socket, reported Thursday. The packages have been available for download for more than two years and accrued roughly 6,200 downloads over that time.

A diversity of attack vectors

“What makes this campaign particularly concerning is the diversity of attack vectors—from subtle data corruption to aggressive system shutdowns and file deletion,” Pandya wrote. “The packages were designed to target different parts of the JavaScript ecosystem with varied tactics.”

When web services shut down and have time to put up a blog post about it, there's typically some real understatement in their explanation of "why." Bookmarking service Pocket's goodbye post truly delivers on this front, noting almost off-handedly that "the way people use the web has evolved." Yes, you might just say that.

Both Pocket and another browser add-on, Fakespot, are being shut down by Firefox maker Mozilla in early July. In a post about the closures, Mozilla cites the need to "invest our time and resources so we can make the biggest impact." Pocket's saving and curation powers will be implemented into Firefox, while Fakespot's analysis of online shopping reviews "didn't fit a model we could sustain."

Pocket started in 2007 as Read It Later, a way to bookmark web articles for later reading. It's not just the focus on published text articles that now seems quaint but also the idea that there was a finite amount of web material you would get back to and would have the time to do so. Those who do want that nice-sounding media experience can cobble it together in most modern browsers, which have built-in tools for managing bookmarks, distinct "reading lists," and even creating stripped-down "readable" versions of articles.

The Federal Aviation Administration gave the green light Thursday for SpaceX to launch the next test flight of its Starship mega-rocket as soon as next week, following two consecutive failures earlier this year.

The failures set back SpaceX's Starship program by several months. The company aims to get the rocket's development back on track with the upcoming launch, Starship's ninth full-scale test flight since its debut in April 2023. Starship is central to SpaceX's long-held ambition to send humans to Mars and is the vehicle NASA has selected to land astronauts on the Moon under the umbrella of the government's Artemis program.

In a statement Thursday, the FAA said SpaceX is authorized to launch the next Starship test flight, known as Flight 9, after finding the company "meets all of the rigorous safety, environmental and other licensing requirements."

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets can form around each of them. But there are also plenty of tight binary systems, where the stars orbit each other at a radius that would place them both comfortably inside our Solar System. In these systems, exoplanets tend to be found at greater distances, in orbits that have them circling both stars.

On Wednesday, scientists described a system that seems to be neither of the above. It is a tight binary system, with a heavy central star that's orbited by a white dwarf at a distance two to three times larger than Earth's orbit. The lone planet confirmed to be in the system is squeezed in between the two, orbiting at a distance similar to Earth's distance from the Sun. And, as an added bonus, the planet is orbiting backward relative to the white dwarf.

Orbiting ν Octantis

The exosolar system is termed ν Octantis (or Nu Octantis), and its primary star is just a bit heavier than our Sun (1.6 solar masses). It's orbited by a far dimmer companion that's roughly half of our Sun's mass, but which hasn't been characterized in detail until now. The companion's orbit relative to the central star is a bit lopsided, ranging from about two astronomical units (AU, the typical Earth-Sun distance) at its closest approach to roughly three AU at its farthest. And, until yesterday, the exact nature of the companion star was not clear.

AT&T has struck a deal to buy CenturyLink's consumer fiber broadband division for $5.75 billion, giving the Internet provider another 1.1 million fiber customers in 11 states.

The all-cash deal is expected to close during the first half of 2026 assuming the companies obtain regulatory approval. AT&T will gain new customers in Arizona, Colorado, Florida, Idaho, Iowa, Minnesota, Nebraska, Nevada, Oregon, Utah, and Washington.

The deal will give AT&T room to grow its user base by more than the 1.1 million existing CenturyLink customers, as AT&T said the network areas being sold include over 4 million fiber-enabled locations. "The transaction will enable AT&T to significantly expand access to AT&T Fiber in major metro areas like Denver, Las Vegas, Minneapolis-St. Paul, Orlando, Phoenix, Portland, Salt Lake City and Seattle, as well as additional geographies," AT&T said.

Ever since a mourning mother, Megan Garcia, filed a lawsuit alleging that Character.AI's dangerous chatbots caused her son's suicide, Google has maintained that—so it could dodge claims that it had contributed to the platform's design and was unjustly enriched—it had nothing to do with C.AI's development.

But Google lost its motion to dismiss the lawsuit on Wednesday after a US district judge, Anne Conway, found that Garcia had plausibly alleged that Google played a part in C.AI's design by providing a component part and "substantially" participating "in integrating its models" into C.AI. Garcia also plausibly alleged that Google aided and abetted C.AI in harming her son, 14-year-old Sewell Setzer III.

Google similarly failed to toss claims of unjust enrichment, as Conway suggested that Garcia plausibly alleged that Google benefited from access to Setzer's user data. The only win for Google was a dropped claim that C.AI makers were guilty of intentional infliction of emotional distress, with Conway agreeing that Garcia didn't meet the requirements, as she wasn't "present to witness the outrageous conduct directed at her child."

Do you miss the feel of tactile buttons on your kitchen appliances or lament car manufacturers' insistence on touchscreens? Have you ever found yourself clumsily fumbling with the door handles of a vehicle or distracted by the bright blue light beaming from your vacuum or Wi-Fi router?

If so, you're not alone. The way technology gadgets are designed largely relies on things like blue, often LED, lights, flat resistive or capacitive touch input, and software. Some, like Amber Case, founder of the Calm Tech Institute, believe that these design choices distract from devices' purpose and functionality and are calling for a new approach to product design.

"Calm Tech Institute is kind of a consumer advocacy body that's collecting stories and research from neuroscientists that says, look at how the mind wants texture, and look at how it wants physical buttons, and there's a part of your mind that needs [those]," Case told Ars Technica. "When we don't have it and we replace it with glass, we're not only losing something about human experience, but we're actually causing the mind stress.”

I initially felt bad for the Medeo T9 City e-bike that Gazelle sent me for review. Not through any fault of its own but because I had just recently ridden Gazelle's Eclipse C380+, an all-inclusive beast that retailed for roughly 2.5 times the price of the Medeo T9 City. Would the lower-priced bike, with different versions of some of the same hardware, suffer compared to its beefier brethren?

Short answer: not really. The Medeo T9 City isn't trying to dominate the road; it just wants to get you where you're going. It has the same kind of automatic electric assist level shifting, just packed into a smaller handlebar display instead of a center console. It has chain and gear cogs instead of the Eclipse's belt drive and stepless shifting, an external battery instead of an inline, and a 250-watt Bosch Active Line motor instead of a 350-watt Performance Line Speed.

I think the Medeo T9 City likely makes for a good first or second e-bike, or perhaps a nice upgrade if you're prioritizing comfort and transport. Given its hill-smoothing motor, wide range of sizes, stable ride feel, and the backing of known bike brands, you could do much worse than a Gazelle with a Bosch motor.

VMware's business model under Broadcom is "legally and ethically flawed," a group of cloud service provider (CSP) customers and partners alleged in a report released today.

The report (PDF) comes from the European Cloud Competition Observatory (ECCO), which describes itself as "independent monitoring body" composed of members of the Cloud Infrastructure Services Providers in Europe (CISPE) trade association, "with the support—acting as observers—of European customer organizations." ECCO says its goals include "highlighting ongoing or new unfair software licensing practices from any software vendors in the cloud sector," and it has previously written similar reports about Broadcom and Microsoft.

In its announcement of the report, ECCO said that CISPE members have met with Broadcom once about the changes it has made to VMware's business model, which is now built around subscriptions of bundled products, but didn't see any changes.
