Smart sous vide cooker to start charging $2/month for 10-year-old companion app

Anova Precision Cooker 3.0

Anova, a company that sells smart sous vide cookers, is getting backlash from customers after announcing that it will soon charge a subscription fee for the device’s companion app.

Sous vide cooking, per Ars Technica sister site Bon appétit, “is the process of sealing food in an airtight container—usually a vacuum sealed bag—and then cooking that food in temperature-controlled water.” Sous vide translates from French to “under vacuum,” and this cooking method ensures that the water stays at the desired temperature for the ideal cook.

Anova was founded in 2013 and sells sous vide immersion circulators. Its current third-generation Precision Cooker 3.0 has an MSRP of $200. Anova also sells a $149 model and a $400 version that targets professionals. It debuted the free Anova Culinary App in 2014.

In a blog post on Thursday, Anova CEO and cofounder Stephen Svajian announced that starting on August 21, people who sign up to use the Anova Culinary App with the cooking devices will have to pay $2 per month, or $10 per year. The app does various things depending on the paired cooker, but it typically offers sous vide cooking guides, cooking notifications, and the ability to view, save, bookmark, and share recipes.

The subscription fee will only apply to people who make an account after August 21. Those who downloaded the app and made an account before August 21 won’t have to pay. But everyone will have to make an account; some people have been using the app without one until now.

“You helped us build Anova, and our intent is that you will be grandfathered in forever,” Svajian wrote.

According to Svajian, the subscription fees are necessary so Anova can “continue delivering the exceptional service and innovative recipes” and “maintain and enhance the app, ensuring it remains a valuable resource.”

As Digital Trends pointed out, the announcement follows an Anova statement saying it will no longer let users remotely control their kitchen gadgets via Bluetooth starting on September 28, 2025. This means that remote control via the app will only be possible for models offering and using Wi-Fi connectivity. Owners of affected devices will no longer be able to access their device via the Anova app, get notifications, or use status monitoring. Users will still be able to manually set the time, temperature, and timer via the device itself.

Customers are heated

Changing or removing features of a tech gadget people have already purchased is a risky move that can anger customers who have paid for a device they expected to work a certain way indefinitely.

As of this writing, there are 104 comments under Anova’s blog post, with many posters saying they will not purchase or recommend another Anova device because of the changes. Many echo a commenter named Nathan Johnson, who wrote, “You’ve just lost a LONGTIME and very faithful customer.”

Another commenter going by Tony Nguyen wrote, “Charging a subscription fee for feature that was free before is anti-consumer. I will never buy another Anova product again and will share with everyone I know how terrible and greedy this company is. You’ve lost me and all my family and friends as customer…”

Facing “financial crisis,” Russia on pace for lowest launch total in 6 decades

SMO fallout —

“This forces us to build a new economy in severe conditions.”

A Progress cargo supply spacecraft launched from the Baikonur Cosmodrome in Kazakhstan early on Thursday, local time. The mission was successful, and Russia has launched hundreds of these spacecraft before. So it wasn’t all that big of a deal, except for one small detail: This was just Russia’s ninth orbital launch of the year.

At this pace, it appears that the country’s space program is on pace for the fewest number of Russian or Soviet space launches in a year since 1961. That was when Yuri Gagarin went to space at the dawn of the human spaceflight era.

There are myriad reasons for this, including a decision by Western space powers to distance themselves from the Russian space corporation, Roscosmos, after the invasion of Ukraine. This has had disastrous effects on the Russian space program, but only recently have we gotten any insight into how deep those impacts have cut.

In recent weeks, the first deputy director of Roscosmos, Andrei Yelchaninov, has given a series of interviews to Russian news outlets. (Most Russian media are state-owned or state-controlled, so none of this information can be independently verified, but it is interesting nonetheless.) One of the most revealing of these interviews was given to national news agency Interfax. It was translated for Ars by Rob Mitchell and provides perspective on Russia’s space crisis and how the country will seek to rebound.

A financial crisis

“We are in an ongoing process of emerging from financial crisis, and it’s complicated,” Yelchaninov told Interfax. “I would remind you that contract cancellations by unfriendly contacts cost Roscosmos 180 billion rubles ($2.1 billion US). This forces us to build a new economy in severe conditions.”

As a result of this, Russia’s space industry has been operating at a loss in recent years and may not begin to break even until 2025. Russia’s invasion of Ukraine also came as United Launch Alliance finally ended its practice of purchasing RD-180 rocket engines, manufactured by NPO Energomash. This fact, in concert with decreased commercial demand for Russia’s Proton and Soyuz rockets, has forced the Russian government to subsidize these elements of Roscosmos.

These companies “are currently in a financial revitalization procedure and have received State subsidies several years ago in order to maintain viability, and are now seeking new sales markets and additional workload,” Yelchaninov said. Asked about possibly selling more Russian-made engines to the United States, Yelchaninov replied, “That issue is not on the agenda.”

Russia had to look to new sales markets after what Yelchaninov euphemistically refers to as the “special military operation,” which is Russia’s term of art for its war against Ukraine. “After the beginning of the SMO we were forced to shift from our traditional partners in Europe and the US, with whom we had many years of interaction, for new international directions including the countries in Africa, the Mideast, and Southeast Asia,” he said.

During the interview, Yelchaninov confirmed that Russia has committed to participating in the International Space Station program until “at least” 2028. NASA is pushing to extend the operational lifetime of the station to 2030, at which point the United States plans to de-orbit the aging laboratory using a modified Crew Dragon spacecraft.

Rather than working with the United States in space, Yelchaninov said that Russia’s space program would focus on cooperation with China rather than competition there. “The key project of our bilateral cooperation is creating an International Lunar Station to which we are jointly striving to attract additional international partners,” he said.

Big plans, big delays?

In addition, Russia is also continuing the development of its oft-delayed “Russian Orbital Station,” or ROS. The current plans call for the launch of a scientific and power module in 2027, with the core of the station (four modules) to be launched into orbit by 2030. Further expansions will take place in the early 2030s. It should be noted, however, that these dates can charitably be described as aspirational.

Even more speculatively, Yelchaninov mentioned several future rocket projects, including the Amur-LNG vehicle and the Corona rocket.

In 2020, Russia aimed to debut the methane-powered Amur rocket with a reusable first stage by 2026. This vehicle was developed to be cost-competitive with SpaceX’s Falcon 9 rocket. Yelchaninov now said Roscosmos intends to develop first-stage reuse in two phases. In the first of these, a Grasshopper-like program would test landing technologies before moving to experiments with a complete booster. But don’t expect to see Amur any time soon. Yelchaninov revealed that Russian and Kazakh officials are still in the design phase of a launch site at Baikonur, rather than actively building anything.

Yelchaninov also said Roscosmos would like to develop a single-stage-to-orbit rocket named Corona in the future. This appears to be an updated take on a Russian rocket design that is more than three decades old.

“We have already studied whether or not a new booster of this type will be in demand,” Yelchaninov said. “The answer is obvious—we are reducing the cost of access to space by more than an order of magnitude and discovering entirely new opportunities for super-operational delivery of cargo, and we are moving toward an ideology of space as a service.”

I would not hold my breath on seeing Corona fly.

NASA shuts down asteroid-hunting telescope, but a better one is on the way

Prolific —

The NEOWISE spacecraft is on a course to fall out of orbit in the next few months.

Last week, NASA decommissioned a nearly 15-year-old spacecraft that discovered 400 near-Earth asteroids and comets, closing an important chapter in the agency’s planetary defense program.

From its position in low-Earth orbit, the spacecraft’s infrared telescope scanned the entire sky 23 times and captured millions of images, initially searching for infrared emissions from galaxies, stars, and asteroids before focusing solely on objects within the Solar System.

Wising up to NEOs

The Wide-field Infrared Survey Explorer, or WISE, spacecraft launched in December 2009 on a mission originally designed to last seven months. After WISE completed checkouts and ended its primary all-sky astronomical survey, NASA put the spacecraft into hibernation in 2011 after its supply of frozen hydrogen coolant ran out, reducing the sensitivity of its infrared detectors. But astronomers saw that the telescope could still detect objects closer to Earth, and NASA reactivated the mission in 2013 for another decade of observations.

The reborn mission was known as NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer). Its purpose was to use the spacecraft’s infrared vision to detect faint asteroids and comets on trajectories that bring them close to Earth.

“We never thought it would last this long,” said Amy Mainzer, NEOWISE’s principal investigator from the University of Arizona and UCLA.

Ground controllers at NASA’s Jet Propulsion Laboratory in California sent the final command to the NEOWISE spacecraft on August 8. The spacecraft, currently at an altitude of about 217 miles (350 kilometers), is falling out of orbit as atmospheric drag slows it down. NASA expects the spacecraft will reenter the atmosphere and burn up before the end of this year, a few months earlier than expected, due to higher levels of solar activity, which causes expansion in the upper atmosphere. The satellite doesn’t have its own propulsion to boost itself into a higher orbit.

“The Sun’s just been incredibly quiet for many years now, but it’s picking back up, and it was the right time to let it go,” Mainzer told Ars.

Astronomers have used ground-based telescopes to discover most of the near-Earth objects detected so far. But there’s an advantage to using a space-based telescope, because Earth’s atmosphere absorbs most of the infrared energy coming from faint objects like asteroids.

With ground-based telescopes, astronomers are “predominantly seeing sunlight reflecting off the surfaces of the objects,” Mainzer said. NEOWISE measures thermal emissions from the asteroids, giving scientists information about their sizes. “We can actually get pretty good measurements of size with relatively few infrared measurements,” she said.

The telescope on NEOWISE was relatively modest in size, with a 16-inch (40-centimeter) primary mirror, more than 16 times smaller than the mirror on the James Webb Space Telescope. But its wide field of view allowed NEOWISE to scour the sky for infrared light sources, making it well-suited for studying large populations of objects. One of the mission’s most famous discoveries was a comet officially named C/2020 F3, more commonly known as Comet NEOWISE, which became visible to the naked eye in 2020. As the comet moved closer to Earth, large telescopes like Hubble were able to take a closer look.

“The NEOWISE mission has been an extraordinary success story as it helped us better understand our place in the universe by tracking asteroids and comets that could be hazardous for us on Earth,” said Nicola Fox, associate administrator of NASA’s science mission directorate.

What’s out there?

The original mission of WISE and the extended survey of NEOWISE combined to discover 366 near-Earth asteroids and 34 comets, according to the Center for Near-Earth Object Studies. Of these, 64 were classified as potentially hazardous asteroids, meaning they come within 4.65 million miles (7.48 million kilometers) of Earth and are at least 500 feet (140 meters) in diameter. These are the objects astronomers want to find and track in order to predict if they pose a risk of colliding with Earth.

There are roughly 2,400 known potentially hazardous asteroids, but there are more lurking out there. Another advantage of using space-based telescopes to search for these asteroids is that they can observe 24 hours a day, while telescopes on the ground are limited to nighttime surveys. Some hazardous asteroids, such as the house-sized object that exploded in the atmosphere over Chelyabinsk, Russia, in 2013, approach Earth from the direction of the Sun. A space telescope has a better chance of finding these kinds of asteroids.

WISE, and then the extended mission of NEOWISE, helped scientists estimate there are approximately 25,000 near-Earth objects.

“The objects (NEOWISE) did discover tended to be overwhelmingly just dark, [and] these are the objects that are much more likely to be missed by the ground-based telescopes,” Mainzer said. “So that, in turn, gives us a much better idea of how many are really out there.”

Scientists solved mysterious origin of Stonehenge’s Altar Stone: Scotland

The Altar Stone at Stonehenge.

Enlarge / The Altar Stone at Stonehenge weighs roughly 6 tons and was probably transported by land—or possibly by sea.

English Heritage

The largest of the “bluestones” that comprise the inner circle at Stonehenge is known as the Altar Stone. Like its neighbors, scientists previously thought the stone had originated in western Wales and been transported some 125 miles to the famous monument that still stands on the Salisbury Plain in Wiltshire, England. But a new paper published in the journal Nature came to a different conclusion based on fresh analysis of its chemical composition: The Altar Stone actually hails from the very northeast corner of Scotland.

“Our analysis found specific mineral grains in the Altar Stone are mostly between 1,000 to 2,000 million years old, while other minerals are around 450 million years old,” said co-author Anthony Clarke, a graduate student at Curtin University in Australia, who grew up in Mynydd Preseli in Wales—origin of most of the bluestones—and first visited the monument when he was just a year old. “This provides a distinct chemical fingerprint suggesting the stone came from rocks in the Orcadian Basin, Scotland, at least 750 kilometers [450 miles] away from Stonehenge.”

As previously reported, Stonehenge consists of an outer circle of vertical sandstone slabs (sarsen stones), connected on top by horizontal lintel stones. There is also an inner ring of smaller bluestones and, within that ring, several free-standing trilithons (larger sarsens joined by one lintel). Radiocarbon dating indicates that the inner ring of bluestones was set in place between 2400 and 2200 BCE. But the standing arrangement of sarsen stones wasn’t erected until around 500 years after the bluestones.

No contemporary written records exist concerning the monument’s construction, and scholars have pondered its likely use and cultural significance for centuries. Stonehenge’s form (and maybe its purpose) changed several times over the centuries, and archaeologists are still trying to piece together the details of its story and the stories of the people who built it and gathered in its circles.

In 2019, Parker Pearson and several colleagues reported the results of their investigation into the quarry source for the bluestones. They found that the 42 bluestones came all the way from western Wales. Chemical analysis has even matched some of them to two particular quarries on the northern slopes of the Preseli Hills.

One quarry, an outcrop called Carn Goedog, seems to have supplied most of the bluish-gray, white-speckled dolerite at Stonehenge. And another outcrop in the valley below, Craig Rhos-y-felin, supplied most of the rhyolite. When another group of archaeologists studied the chemical isotope ratios in the cremated remains of people once buried beneath the bluestones, those researchers found that many of those people may have come from the same part of Wales between 3100 and 2400 BCE.

But the sarsen stones hail from much closer to home. Since the 1500s, most Stonehenge scholars have assumed the sarsen stones came from nearby Marlborough Downs, an area of round, grassy hills 25 to 30km (17 miles) north of Stonehenge, which has the largest concentration of sarsen in the UK. A 2020 study by University of Brighton archaeologist David Nash and colleagues confirmed that.

Fifty of the sarsens shared very similar chemical fingerprints, which means they probably all came from the same place, most likely one site in the southeastern Marlborough Downs: West Woods, about 25 km (16 miles) north of Stonehenge and just 3 km (2 miles) south of where most earlier studies had looked for Neolithic sarsen quarries. The other two surviving sarsens came from two different places, which archaeologists haven’t pinpointed yet.

ISPs worry that killing FCC net neutrality rules will come back to haunt them

ISPs asked the US Supreme Court to strike down a New York law that requires broadband providers to offer $15-per-month service to people with low incomes. On Monday, a Supreme Court petition challenging the state law was filed by six trade groups representing the cable, telecom, mobile, and satellite industries.

Although ISPs were recently able to block the FCC’s net neutrality rules, this week’s petition shows the firms are worried about states stepping into the regulatory vacuum with various kinds of laws targeting broadband prices and practices. A broadband-industry victory over federal regulation could bolster the authority of New York and other states to regulate broadband. To prevent that, ISPs said the Supreme Court should strike down both the New York law and the FCC’s broadband regulation, although the rulings would have to be made in two different cases.

A situation in which the New York law is upheld while federal rules are struck down “will likely lead to more rate regulation absent the Court’s intervention,” ISPs told the Supreme Court. “Other States are likely to copy New York once the Attorney General begins enforcing the ABA [Affordable Broadband Act] and New York consumers can buy broadband at below-market rates. As petitioners’ members have shown, New York’s price cap will require them to sell broadband at a loss and deter them from investing in expanding their broadband networks. As rate regulation proliferates, those harms will as well, stifling critical investment in bringing broadband to unserved and underserved areas.”

The New York law was upheld in April by the US Court of Appeals for the 2nd Circuit, which reversed a 2021 District Court ruling. New York Attorney General Letitia James agreed last week not to enforce the $15 broadband law while the Supreme Court considers whether to take up the case.

“Although New York has agreed not to enforce its rate-regulation law while the Court resolves this petition, New York continues to assert that it has the right to do what the FCC cannot,” ISPs wrote. “This case thus presents the question whether broadband services will remain protected from common-carrier treatment and rate regulation by individual States.”

NY law’s fate tied to FCC regulation

The fate of the New York law is tied in part to the Federal Communications Commission’s April 2024 decision to revive net neutrality rules and regulate ISPs as common carriers under Title II of the Communications Act. When New York enacted its affordability law, the FCC was not regulating ISPs under Title II. The lack of federal regulation gave states more leeway to implement their own laws.

When judges at the 2nd Circuit upheld the New York law, they wrote that “a federal agency cannot exclude states from regulating in an area where the agency itself lacks regulatory authority.” If the FCC’s revived common-carrier regulations are upheld, ISPs would have a better chance at overturning the New York law.

But ISPs are trying to get the net neutrality and common-carrier regulations overturned—and having success on that front. The US Court of Appeals for the 6th Circuit stayed enforcement of the FCC regulations while litigation is pending, and a panel of judges said that ISPs are likely to win the case. The “broadband providers have shown that they are likely to succeed on the merits,” 6th Circuit judges wrote.

ISPs are worried that if they succeed in killing the FCC regulation, they will be subject to many state laws like New York’s. “The upshot of the Sixth Circuit and Second Circuit decisions is that each State can now do what the FCC cannot—subject an interstate information service to common-carrier regulation, including rate regulation,” ISP lobby groups said in their Supreme Court petition. This will be “to the detriment of providers, consumers, and the nation,” they claimed.

ISPs asked the Supreme Court to “confirm that the federal Communications Act—not a patchwork of state laws—governs the regulation of interstate communications services such as broadband.”

Self-driving Waymo cars keep SF residents awake all night by honking at each other

The ghost in the machine —

Haunted by glitching algorithms, self-driving cars disturb the peace in San Francisco.

Silicon Valley’s latest disruption? Your sleep schedule. On Saturday, NBC Bay Area reported that San Francisco’s South of Market residents are being awakened throughout the night by Waymo self-driving cars honking at each other in a parking lot. No one is inside the cars, and they appear to be automatically reacting to each other’s presence.

Videos provided by residents to NBC show Waymo cars filing into the parking lot and attempting to back into spots, which seems to trigger honking from other Waymo vehicles. The automatic nature of these interactions—which seem to peak around 4 am every night—has left neighbors bewildered and sleep-deprived.

NBC Bay Area’s report: “Waymo cars keep SF neighborhood awake.”

According to NBC, the disturbances began several weeks ago when Waymo vehicles started using a parking lot off 2nd Street near Harrison Street. Residents in nearby high-rise buildings have observed the autonomous vehicles entering the lot to pause between rides, but the cars’ behavior has become a source of frustration for the neighborhood.

Christopher Cherry, who lives in an adjacent building, told NBC Bay Area that he initially welcomed Waymo’s presence, expecting it to enhance local security and tranquility. However, his optimism waned as the frequency of honking incidents increased. “We started out with a couple of honks here and there, and then as more and more cars started to arrive, the situation got worse,” he told NBC.

The lack of human operators in the vehicles has complicated efforts to address the issue directly since there is no one they can ask to stop honking. That lack of accountability forced residents to report their concerns to Waymo’s corporate headquarters, which had not responded to the incidents until NBC inquired as part of its report. A Waymo spokesperson told NBC, “We are aware that in some scenarios our vehicles may briefly honk while navigating our parking lots. We have identified the cause and are in the process of implementing a fix.”

The absurdity of the situation prompted tech author and journalist James Vincent to write on X, “current tech trends are resistant to satire precisely because they satirize themselves. a car park of empty cars, honking at one another, nudging back and forth to drop off nobody, is a perfect image of tech serving its own prerogatives rather than humanity’s.”

Through a cloud-washed blue sky above Launch Pad 39A, Space Shuttle <em>Columbia</em> hurtles toward space on mission STS-107. ” src=”https://cdn.arstechnica.net/wp-content/uploads/2016/01/16271647815_f0b8187e11_o-640×474.jpg”></img><figcaption>
<p>Through a cloud-washed blue sky above Launch Pad 39A, Space Shuttle <em>Columbia</em> hurtles toward space on mission STS-107. </p>
<p>NASA</p>
</figcaption></figure>
<p>My first real taste of space journalism came on the morning of February 1, 2003. An editor at the Houston Chronicle telephoned me at home on a Saturday morning and asked me to hurry to Johnson Space Center to help cover the loss of Space Shuttle <em>Columbia</em>.</p>
<p>At the time, I did not realize this tragedy would set the course for the rest of my professional life, that of thinking and writing about spaceflight. This would become the consuming passion of my career.</p>
<p>I’ve naturally been thinking a lot about <em>Columbia</em> in recent weeks. While the parallels between that Space Shuttle mission and the first crewed flight of Boeing’s Starliner spacecraft are not exact, there are similarities. Most significantly, after the Space Shuttle launched, there were questions about the safety of the vehicle’s return home due to foam striking the leading edge of the spacecraft’s wing.</p>
<p>Two decades later, there are many more questions, both in public and private, about the viability of Starliner’s propulsion system after irregularities during the vehicle’s flight to the space station in June. NASA officials made the wrong decision during the <em>Columbia</em> accident. So, facing another <a href=hugely consequential decision now, is there any reason to believe they’ll make the correct call with the lives of Starliner astronauts Butch Wilmore and Suni Williams on the line?

A poor safety culture

To understand Columbia, we need to go back to 1986 and the first Space Shuttle accident involving Challenger. After that catastrophic launch failure, the Rogers Commission investigated and identified the technical cause of the accident while also concluding that it was rooted in a flawed safety culture.

This report prompted sweeping changes in NASA’s culture that were designed to allow lower-level engineers the freedom to raise safety concerns about spaceflight vehicles and be heard. And for a time, this worked. However, by the time of Columbia, when the shuttle had flown many dozens of successful missions, NASA’s culture had reverted to Challenger-like attitudes.

Because foam strikes had been seen during previous shuttle missions without consequence, observations of foam loss from the external tank during Columbia‘s launch were not a significant cause of concern. There were a few dissenting voices who said the issue deserved more analysis. However, the chair of the Mission Management Team overseeing the flight, Linda Ham, blocked a request to obtain imagery of the possibly damaged orbiter from US Department of Defense assets in space. The message from the top was clear: The shuttle was fine to come home.

The loss of Columbia resulted in another investigatory commission, known as the Columbia Accident Investigation Board. One of its members was John Logsdon, an eminent space historian at George Washington University. “We observed that there had been changes after Challenger and that they had gone away, and they didn’t persist,” Logsdon told me in an interview this weekend. “NASA fell back into the pattern that it had been in before Challenger.”

Essentially, then, antibodies within the NASA culture had rebounded to limit dissent.

Advantages for decision-makers today

If it does not precisely repeat itself, history certainly echoes. Two decades after Columbia, Starliner is presently docked to the International Space Station. As with foam strikes, issues with reaction-control system thrusters are not unique to this flight; they were also observed during the previous test flight in 2022. So once again, engineers at NASA are attempting to decide whether they can be comfortable with a “known” issue and all of its implications for a safe return to Earth.

NASA is the customer for this mission rather than the operator—the space agency is buying transportation services to the International Space Station for its astronauts from Boeing. However, as the customer, NASA still has the final say. Boeing engineers will have input, but the final decisions will be made by NASA engineers such as Steve Stich, Ken Bowersox, and Jim Free. Ultimately, NASA Administrator Bill Nelson could have the final say.

The Witch’s Road might take everything in Agatha All Along D23 trailer

witchy women —

“The Witch’s Road will give you the thing you want most… if you make it to the end.”

Kathryn Hahn seeks a new witchy coven in Agatha All Along.

Disney introduced the poster and first full trailer for Agatha All Along during its annual D23 Expo this weekend. The nine-episode series, starring Kathryn Hahn, is one of the TV series in the MCU’s Phase Five, coming on the heels of Secret Invasion, Loki S2, What If…? S2, and Echo.

(Spoilers for WandaVision below.)

As reported previously, Agatha All Along has been in the works since 2021, officially announced in November of that year, inspired by Hahn’s breakout performance in WandaVision as nosy neighbor Agnes—but secretly a powerful witch named Agatha Harkness who was conspiring to steal Wanda’s power. The plot twist even inspired a meta-jingle that went viral. That series ended with Wanda victorious and Agatha robbed of all her powers, trapped in her nosy neighbor persona.

Head writer Jac Schaeffer (who also created WandaVision) has said that the series would follow Agatha as she forms her own coven with “a disparate mixed bag of witches… defined by deception, treachery, villainy, and selfishness” who must learn to work together. And apparently we can expect a few more catchy tunes—one of which is front and center in the new trailer. This new series picks up where WandaVision left Agatha. Per the official premise:

The infamous Agatha Harkness finds herself down and out of power after a suspicious goth teen helps break her free from a distorted spell. Her interest is piqued when he begs her to take him on the legendary Witches’ Road, a magical gauntlet of trials that, if survived, rewards a witch with what they’re missing. Together, Agatha and this mysterious teen pull together a desperate coven, and set off down, down, down The Road…

In addition to Hahn, the cast includes Aubrey Plaza as warrior witch Rio Vidal; Joe Locke as Billy, a gay teenage familiar; Patti LuPone as a 450-year-old Sicilian witch named Lilia Calderu; Sasheer Zamata as sorceress Jennifer Kale; Ali Ahn as a witch named Alice; and Miles Gutierrez-Riley as Billy’s boyfriend.

Debra Jo Rupp reprises her WandaVision role as Sharon Davis (“Mrs. Hart” in the meta-sitcom), here becoming a member of Agatha’s coven. Also reprising their WandaVision roles: Emma Caulfield Ford as Sarah Proctor (aka “Dottie Jones”); David Payton as John Collins (“Herb”); David Lengel as Harold Proctor (“Phil Jones”); Asif Ali as Abilash Tandon (“Norm”); Amos Glick (pizza delivery man “Dennis”); Kate Forbes as Agatha’s mother, Evanora; and Brian Brightman as the Eastview, New Jersey, sheriff.

The first two episodes of Agatha All Along drop on September 18, 2024, on Disney+, with episodes airing weekly after that through November 6.

520-million-year-old larva fossil reveals the origins of arthropods

Loads of lobopods —

Around half a billion years ago, in what is now the Yunnan Province of China, a tiny larva was trapped in mud. Hundreds of millions of years later, after the mud had long since become the black shales of the Yuan’shan formation, the larva surfaced again, a meticulously preserved time capsule that would unearth more about the evolution of arthropods.

Youti yuanshi is barely visible to the naked eye. Roughly the size of a poppy seed, it is preserved so well that its exoskeleton is almost completely intact, and even the outlines of what were once its internal organs can be seen through the lens of a microscope. Durham University researchers who examined it were able to see features of both ancient and modern arthropods. Some of these features told them how the simpler, more wormlike ancestors of living arthropods evolved into more complex organisms.

The research team also found that Y. yuanshi, which existed during the Cambrian Explosion (when most of the main animal groups started to appear on the fossil record), has certain features in common with extant arthropods, such as crabs, velvet worms, and tardigrades. “The deep evolutionary position of Youti yuanshi… illuminat[es] the internal anatomical changes that propelled the rise and diversification of [arthropods],” they said in a study recently published in Nature.

Inside out and outside in

While many fossils preserved in muddy environments like the Yuan’shan formation are flattened by compression, Y. yuanshi remained three-dimensional, making it easier to examine. So what exactly did this larva look like on the outside and inside?

The research team could immediately tell that Y. yuanshi was a lobopodian. Lobopodians are a group of extinct arthropods with long bodies and stubby legs, or lobopods. There is a pair of lobopods in the middle of each of its twenty segments, and these segments also get progressively shorter from the front to back of the body. Though soft tissue was not preserved, spherical outlines suggest an eye on each side of the head, though whether these were compound eyes is unknown. This creature had a stomodeum—the precursor to a mouth—but no anus. It would have had to both take in food and dispose of waste through its mouth.

Youti yuanshi has a cavity, known as the perivisceral cavity, that surrounds the outline of a tube that is thought to have once been the gut. The creature’s gut ends without an opening, which explains its lack of an anus. Inside each segment, there is a pair of voids toward the middle. The researchers think these are evidence of digestive glands, especially after comparing them to digestive glands in the fossils of other arthropods from the same era.

A ring around the mouth of the larva was once a circumoral nerve ring, which connected with nerves that extend to eyes and appendages in the first segment. Inside its head is a void that contained the brain. The shape of this empty chamber gives some insight into how the brain was structured. From what the researchers could see, the brain of Y. yuanshi had wedge-shaped frontal portion, and the rest of the brain was divided into two sections, as evidenced by the outline of a membrane in between them.

Way, way, way back then and now

Given its physical characteristics, the researchers think that Y. yuanshi displays features of both extinct and extant arthropods. Some are ancestral characteristics present in all arthropods, living and extinct. Others are ancestral characteristics that may have been present in extinct arthropods but are only present in some living arthropods.

Among the features present in all arthropods today is the protocerebrum; its evolutionary precursor was the circumoral nerve ring present in Y. yuanshi. The protocerebrum is the first segment of the arthropod brain, which controls the eyes and appendages, such as antennae in velvet worms and the mouthparts in tardigrades. Another feature of Y. yuanshi present in extant and extinct arthropods is its circulatory system, which is similar to that of modern arthropods, especially crustaceans.

Lobopods are a morphological feature of Y. yuanshi that are now found only in some arthropods—tardigrades and velvet worms. Many more species of lobopodians existed during the Cambrian. The lobopodians also had a distinctively structured circulatory system in their legs and other appendages, which is closest to that of velvet worms.

“The architecture of the nervous system informs the early configuration of the [arthropod] brain and its associated appendages and sensory organs, clarifying homologies across [arthropods],” the researchers said in the same study.

Yuti yuanshi is still holding on to some mysteries. They mostly have to do with the fact that it is a larva—what it looked like as an adult can only be guessed at, and it’s possible that this species developed compound eyes or flaps for swimming by the time it reached adulthood. Whether it is the larva of an already-known species of extinct lobopod is an open question. Maybe the answers are buried somewhere in the Yuan’shan shale.

More than greenwashing? Sustainable aviation fuels struggle to take off

Last November, Virgin Atlantic Airways made headlines for completing the world’s first transatlantic flight using “100 percent sustainable aviation fuel.”

This week, the Advertising Standard Authority (ASA) of the U.K. banned a Virgin radio ad released prior to the flight, in which they touted their “unique flight mission.” While Virgin did use fuel that releases fewer emissions than traditional supplies, the regulatory agency deemed the company’s sustainability claim “misleading” because it failed to give a full picture of the adverse environmental and climate impacts of fuel.

“It’s important that claims for sustainable aviation fuel spell out what the reality is, so consumers aren’t misled into thinking that the flight they are taking is greener than it really is,” Miles Lockwood, director of complaints and investigations at the ASA, said in a statement.

The ruling is the latest in a string of greenwashing crackdowns against sustainable aviation fuels (SAFs), which are made of components other than fossil fuels. In recent years, the U.K. and U.S. governments and private sector have offered incentives and funds to help ramp up SAF production. But skeptics say the alternative fuels will hardly make a dent in the airline industry’s large carbon footprint.

Plant-powered flights

Aviation accounts for roughly 2.5 percent of global emissions, largely from the burning of petroleum-based fuels. Sustainable aviation fuels have been made with a number of alternative ingredients—from worn-out tires to plastic waste (though my colleague James Bruggers has previously covered some setbacks in the plastic-to-jet-fuel field).

The majority of SAFs are made using materials already found in the environment, such as cooking fats or plant oils. These alternative fuels still emit carbon dioxide when they burn, but they typically have lower “lifecycle” emissions than petroleum-based fuels due to the way they are harvested. SAFs tap into renewable resources found in the environment instead of fossil fuels that have trapped carbon underground for millions of years.

Currently, international standards require SAFs to be mixed with conventional fuels, which enables airlines to continue using the same infrastructure rather than developing new aircraft that can handle exclusively bio-based accelerants. To qualify as “sustainable” for U.S. tax credits, though, the mixture must cut net emissions by at least 50 percent compared with exclusively oil-based fuels.

Infamous $30 Logitech F710 called out in $50M lawsuit over Titan sub implosion

CBS Sunday Morning

In a 2022 CBS Sunday Morning segment, CEO Stockton Rush of deep-water submersible company OceanGate gave journalist David Pogue a fun reveal. “We run the whole thing with this game controller,” Rush said, holding up a Logitech F710 controller with 3D-printed thumbstick extensions. The controller was wireless, and it was the primary method for controlling the Titan submersible, which would soon make a visit to the wreck of the Titanic. Pogue laughed. “Come on!” he said, covering his eyes with his hand.

Journalists loved the controller story, covering the inexpensive F710 and the ways that video game controllers have become common control solutions in various military and spaceflight applications in recent years. After all, if your engineers and pilots grew up using two-stick controllers to waste their friends in Halo multiplayer, why not use that built-in muscle memory for other purposes?

So the use of a video game controller was not in itself a crazy decision. But after the Titan sub imploded on a June 2023 dive to the Titanic site, killing all five passengers including Stockton Rush, the use of a wireless $30 control interface began to look less “cool!” and more “isn’t that kind of risky?” The only question at that point was how long it would take the Logitech F710 to show up in a lawsuit.

This week, we got our answer. In the first Titan wrongful death lawsuit, filed this week by the estate of Paul-Henri Louis Emile Nargeolet, the Logitech controller comes in for some prominent criticism.

“Hip, contemporary, wireless”

Nargeolet “was known worldwide as ‘Mr. Titanic,'” says the new lawsuit (PDF) against OceanGate, Rush’s estate, and various companies that helped build the Titan. Nargeolet had been on 37 dives to the Titanic wreckage and, on his final dive, was working with OceanGate as a Titan crewmember who would “guide other crewmembers and assist with navigation through the Titanic wreckage, which he knew so well.”

The lawsuit reiterates all the main criticisms of the Titan.

First, the sub was not made from titanium (as most submersibles are), which gets stronger under compression; it was made instead from carbon fiber, which can crack under repeated compression. Rush, who saw himself as an innovator like “Steve Jobs or Elon Musk,” the complaint says, once told Pogue, “At some point, safety just is pure waste.” Rush thought he had found a lighter way to build subs.

Second, the complaint singles out the Titan’s “hip, contemporary, wireless electronics systems.” (Those adjectives are not compliments).

TITAN was piloted using a mass-produced Logitech video game controller (normally used with a PlayStation or Xbox) rather than a controller custom-made for TITAN’s design and operation. Moreover, the controller worked via Bluetooth, rather than being hardwired. TITAN also had only “one button” (for power) within its main chamber—the remainder of its controls (for lights, ballast and so on) and gauges (for depth, oxygen level and so forth) were touchscreen. RUSH stated that TITAN was “to other submersibles what the iPhone was to the BlackBerry.” As with an iPhone, however, none of the controller, controls or gauges would work without a constant source of power and a wireless signal.

OceanGate’s previous submersible, the Cyclops I, had also used a video game controller (a Sony DualShock 3) and some other wireless tech.

The complaint quotes an expert saying that such systems provided “multiple points of failure” and that “‘every sub in the world has hardwired controls for a reason,’ namely that a loss of signal would not imperil the vessel.” But such issues were “disregarded by OceanGate, as Titan employed nearly identical systems to Cyclops I,” says the complaint.

The lawsuit also attacks the engineering team that designed and integrated all the electronics systems into Titan, saying that the team was made up mostly of current or recent Washington State University grads with “virtually no real-world experience and no prior exposure to the deep-sea diving industry.”

The complaint does not allege that the Logitech wireless controller, the carbon fiber construction, Titan’s innovative porthole, or the use of disparate materials with differing expansion/compression coefficients—four main areas of criticism—were individually responsible for the sub’s implosion. But it does suggest that these systems could have together contributed to a “daisy chain of failures of multiple improperly designed or constructed parts or systems.” The complaint says that Nargeolet’s estate is entitled to at least $50 million in damages.

Too good to be true

A final investigatory report from various government agencies has been in process for over a year and has not yet been completed, but it seems likely that the Logitech controller—along with the five people on the sub—is gone forever.

But the prospect of a cheap piece of plastic surviving the catastrophic implosion was just too good for social media to ignore. Shortly after the Titan disaster, people began “sharing a photo that purports to show the controller resting on the bottom of the sea,” according to a 2023 AP fact check. “The image shows a sandy ocean bottom with a part of the photo magnified to supposedly show a close up of the controller.”

“The cheapest part survived,” one X (Twitter) user posted.

Alas, it did not; the photo was a fake.

Ars asks: What was the last CD or DVD you burned?

i like my alcohol at 120% —

With the demise of Apple’s SuperDrive, we reminisce on our final homemade optical discs.

We noted earlier this week that time seems to have run out for Apple’s venerable SuperDrive, which was the last (OEM) option available for folks who still needed to read or create optical media on modern Macs. Andrew’s write-up got me thinking: When was the last time any Ars staffers actually burned an optical disc?

Lee Hutchinson, Senior Technology Editor

It used to be one of the most common tasks I’d do with a computer. As a child of the ’90s, my college years were spent filling and then lugging around giant binders stuffed with home-burned CDs in my car to make sure I had exactly the right music on hand for any possible eventuality. The discs in these binders were all labeled with names like “METAL MIX XVIII” and “ULTRA MIX IV” and “MY MIX XIX,” and part of the fun was trying to remember which songs I’d put on which disc. (There was always a bit of danger that I’d put on “CAR RIDE JAMS XV” to set the mood for a Friday night trip to the movies with all the boys, but I should have popped on “CAR RIDE JAMS XIV” because “CAR RIDE JAMS XV” opens with Britney Spears’ “Lucky”—look, it’s a good song, and she cries in her lonely heart, OK?!—thus setting the stage for an evening of ridicule. Those were just the kinds of risks we took back in those ancient days.)

It took a while to try to figure out what the very last time I burned a disc was, but I’ve narrowed it down to two possibilities. The first (and less likely) option is that the last disc I burned was a Windows 7 install disc because I’ve had a Windows 7 install disc sitting in a paper envelope on my shelf for so long that I can’t remember how it got there. The label is in my handwriting, and it has a CD key written on it. Some quick searching shows I have the same CD key stored in 1Password with an “MSDN/Technet” label on it, which means I probably downloaded the image from good ol’ TechNet, to which I maintained an active subscription for years until MS finally killed the affordable version.

But I think the actual last disc I burned is still sitting in my car’s CD changer. It’s been in there so long that I’d completely forgotten about it, and it startled the crap out of me a few weeks back when I hopped in the car and accidentally pressed the “CD” button instead of the “USB” button. It’s an MP3 CD instead of an audio CD, with about 120 songs on it, mostly picked from my iTunes “’80s/’90s” playlist. It’s pretty eclectic, bouncing through a bunch of songs that were the backdrop of my teenage years—there’s some Nena, some Stone Temple Pilots, some Michael Jackson, some Tool, some Stabbing Westward, some Natalie Merchant, and then the entire back half of the CD is just a giant block of like 40 Cure songs, probably because I got lazy and just started lasso-selecting.

It turns out I left CDs the same way I came to them—with a giant mess of a mixtape.

Connor McInerney, Social Media Manager

Like many people, physical media for me is deeply embedded with sentimentality; half the records in my vinyl collection are hand-me-downs from my parents, and every time I put one on, their aged hiss reminds me that my folks were once my age experiencing this music in the same way. This goes doubly so for CDs as someone whose teen years ended with the advent of streaming, and the last CD I burned is perhaps the most syrupy, saccharine example of this media you can imagine—it was a mixtape for the girl I was dating during the summer of 2013, right before we both went to college.

In hindsight this mix feels particularly of its time. I burned it using my MacBook Pro (the mid-2012 model was the last to feature a CD/DVD drive) and made the artwork by physically cutting and pasting a collage together (which I made the mix’s digital artwork by scanning and adding in iTunes). I still make mixes for people I care about using Spotify—and I often make custom artwork for said playlists with the help of Photoshop—but considering the effort that used to be required, the process feels unsurprisingly unsatisfying in comparison.

As for the musical contents of the mix, imagine what an 18-year-old Pitchfork reader was listening to in 2013 (Vampire Weekend, Postal Service, Fleet Foxes, Bon Iver, and anything else you might hear playing while shopping at an Urban Outfitters) and you’ve got a pretty close approximation.
