The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a merger between two compact objects, one of which has an unusual intermediate mass—heavier than a neutron star and lighter than a black hole. The collaboration provided specifics of their analysis of the merger and the “mystery object” in a draft manuscript posted to the physics arXiv, suggesting that the object might be a very low-mass black hole.

LIGO detects gravitational waves via laser interferometry, using high-powered lasers to measure tiny changes in the distance between two objects positioned kilometers apart. LIGO has detectors in Hanford, Washington state, and in Livingston, Louisiana. A third detector in Italy, Advanced VIRGO, came online in 2016. In Japan, KAGRA is the first gravitational-wave detector in Asia and the first to be built underground. Construction began on LIGO-India in 2021, and physicists expect it will turn on sometime after 2025.

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected mergers involved either two black holes or two neutron stars, but in 2021, LIGO/VIRGO/KAGRA confirmed the detection of two separate “mixed” mergers between black holes and neutron stars.

Most objects involved in the mergers detected by the collaboration fall into two groups: stellar-mass black holes (ranging from a few solar masses to tens of solar masses) and supermassive black holes, like the one in the middle of our Milky Way galaxy (ranging from hundreds of thousands to billions of solar masses). The former are the result of massive stars dying in a core-collapse supernova, while the latter’s formation process remains something of a mystery. The range between the heaviest known neutron star and the lightest known black hole is known as the “mass gap” among scientists.

There have been gravitational wave hints of compact objects falling within the mass gap before. For instance, as reported previously, in 2019, LIGO/VIRGO picked up a gravitational wave signal from a black hole merger dubbed “GW190521,” that produced the most energetic signal detected thus far, showing up in the data as more of a “bang” than the usual “chirp.” Even weirder, the two black holes that merged were locked in an elliptical (rather than circular) orbit, and their axes of spin were tipped far more than usual compared to those orbits. And the new black hole resulting from the merger had an intermediate mass of 142 solar masses—smack in the middle of the mass gap.

That same year, the collaboration detected another signal, GW 190814, a compact binary merger involving a mystery object that also fell within the mass gap. With no corresponding electromagnetic signal to accompany the gravitational wave signal, astrophysicists were unable to determine whether that object was an unusually heavy neutron star or an especially light black hole. And now we have a new mystery object within the mass gap in a merger event dubbed “GW 230529.”

“While previous evidence for mass-gap objects has been reported both in gravitational and electromagnetic waves, this system is especially exciting because it’s the first gravitational-wave detection of a mass-gap object paired with a neutron star,” said co-author Sylvia Biscoveanu of Northwestern University. “The observation of this system has important implications for both theories of binary evolution and electromagnetic counterparts to compact-object mergers.”

LIGO/VIRGO/KAGRA started its fourth observing run last spring and soon picked up GW 230529’s signal. Scientists determined that one of the two merging objects had a mass between 1.2 to 2 times the mass of our sun—most likely a neutron star—while the other’s mass fell in the mass-gap range of 2.5 to 4.5 times the mass of our sun. As with GW 190814, there were no accompanying bursts of electromagnetic radiation, so the team wasn’t able to conclusively identify the nature of the more massive mystery object located some 650 million light-years from Earth, but they think it is probably a low-mass black hole. If so, the finding implies an increase in the expected rate of neutron star–black hole mergers with electromagnetic counterparts, per the authors.

“Before we started observing the universe in gravitational waves, the properties of compact objects like black holes and neutron stars were indirectly inferred from electromagnetic observations of systems in our Milky Way,” said co-author Michael Zevin, an astrophysicist at the Adler Planetarium. “The idea of a gap between neutron-star and black-hole masses, an idea that has been around for a quarter of a century, was driven by such electromagnetic observations. GW230529 is an exciting discovery because it hints at this ‘mass gap’ being less empty than astronomers previously thought, which has implications for the supernova explosions that form compact objects and for the potential light shows that ensue when a black hole rips apart a neutron star.”

After pushing cloud storage, TV provider to auto-delete 61-day-old DVR recordings

Bell Canada, cable, Canada, Cloud, Policy, streaming, Tech / /

“Wish I knew this before” —

Customers originally had 365 days to enjoy the recordings.

Canadian telecom Bell Canada has been pushing its cloud-based DVR service to its Fibe TV subscribers for years. While it has given customers advantages, like the ability to view their recordings from more devices, such as phones, compared to using local DVR storage, users don’t have as much control over the recordings as they thought they had.

On May 1, Fibe TV will automatically delete recordings stored on its Cloud PVR (personal video recorder) offering once the recordings hit 61 days of age, as confirmed by Canadian online newspaper Daily Hive. Currently, customers maintain access to recordings stored via Cloud PVR for 365 days.

Fibe TV apparently started alerting customers of the upcoming change this month.

A Bell Canada spokesperson, Jacqueline Michelis, minimized the idea of disruption to customers, telling Daily Hive: “The viewing of nearly all recordings takes place within 60 days, so there is minimal impact to customers.” Michelis didn’t provide more details on how Bell Canada arrived at this conclusion.

An X user (formerly Twitter) user going by SimonDingleyTV shared what he said was a notice he received from Fibe TV about the policy change. He claimed that a company representative told him that the reason for the change was to “save space.”

Bell updated its website to acknowledge the time limit and noted that Cloud PVR also has a limit of up to 320 hours of recordings. If users surpass that limit, the oldest recordings will start getting deleted.

“Absolutely ridiculous”

Customers have turned to Bell Canada’s online support forum to share their discontent with the changes, with some saying that they don’t align with the services they expected to receive when signing up for Fibe TV. Thankfully, Bell Canada won’t be able to delete recordings stored on DVR hardware inside customers’ homes.

Other complaints are coming from users whose recordings are being deleted even when they haven’t come close to maxing out their cloud storage or if their recordings aren’t available on demand.

A user going by camisotro on Bell Canada’s online support forum called the announcement “absolutely ridiculous” and condemned what they perceived to be years of telecoms pushing back against users’ ability to record content:

… Bell eliminated the option for any device that actually records TV locally, forcing customers onto an inferior TV box with ‘Cloud PVR.’ Now they are nerfing it to a nearly useless 60 days of recording. This is not the service I signed up for on contract, and yet I am still continuing to pay increasing prices.

Like rivals, Bell pushed customers toward cloud-based DVR, with its website stating, “Fibe TV has evolved to a cloud-based storage system for all your recordings.”

However, some users may not have realized the trade-offs.

“Wish I knew this before I traded PVRs to change to cloud storage! No one told us that !!!,” a forum user known as Crazy aunt said.

Another user, Thornquills, called the news a “deal-breaker” because they’re “paying $10.00/month for cloud storage,” and “2 months is too restrictive, in my opinion.”

Meanwhile, Bell Canada rival Rogers Ignite confirmed to The Canadian Press that it will continue allowing its customers to keep DVR recordings stored in the cloud for one year, as its cloud PVR offering exists to “help manage storage capacity.”

Fibe TV’s policy change comes about two months after Bell Canada announced that it was laying off 4,800 workers and selling 45 of its 103 radio stations.

Android’s Bluetooth trackers are finally shipping in late May

Just merge the networks already —

The one-year wait for Apple’s cross-platform safety measures is almost over.

–

  • Chipolo’s trackers. The keychain tracker takes a CR2023 battery; the card is not rechargeable.

  • Pebblebee’s trackers are all rechargeable.

  • Google’s “Find My Device” app.

    Google

After an announcement that ended up being a year early, Android’s version of Tile/AirTags is ready to launch. Google has been gearing up on the software side of things to enable a Bluetooth tracking network on Android, and the company’s two tracking tag hardware partners, Pebblebee and Chipolo, now have ship dates. The two companies each have a press release today, with Pebblebee saying its trackers will ship in “late May,” while Chipolo says it will ship “after May 27th.” Google has a blog post out, too, promising “additional Bluetooth tags from Eufy, Jio, Motorola and more” later this year.

Both sets of devices have been up for preorder for a year now, and it doesn’t seem like anything has changed since. Both companies are offering little Bluetooth trackers in a keychain tag or credit card format, and Pebblebee has a third stick-on tag format. They’ll all be anonymously tracked by Android’s 3 billion-device Bluetooth tracker network, and the device owner will be able to see them in Google’s “Find my device” app.

Chipolo’s “One Point” key chain tag is the only thing that takes a CR2032 coin cell battery, while the company’s credit card tracker is not rechargeable. Pebblebee’s key chain, credit card, and stick-on tracker all have rechargeable batteries, including the wallet card, which is very rare! Nothing has UWB for precise location tracking—everything uses a speaker. Both companies sell multiple SKUs of what look like the exact same product but are locked to Google’s or Apple’s network—no switching allowed.

These were all supposed to come out in 2023 originally. Google’s patch notes say that the tracking network shipped in Android in December 2022, even though nothing is using it. The company has actually been waiting on Apple. In May 2023, Google and Apple announced a joint standard for “unknown tracker” alerts. While the two networks will not be compatible, they will team up to alert users if a tracker is being used to stalk them. All this hardware was announced a week later, but in July 2023, Google shipped what a spokesperson called, “a custom implementation” for AirTags (enabling Android phones to alert users to an unknown AirTag), and the company said it wouldn’t enable its tracking network until the joint tracking detection standard with Apple was ready. It looks like Apple will do that in iOS 17.5. iOS 17.5 is expected to be out—you guessed it—at the end of May, so these tags can finally ship.

9: 00pm update: A Google spokesperson told us Google’s July release of Android’s unwanted AirTag detection is “a custom implementation” and not the joint standard.

A 37-year-old man is fighting for his life in an intensive care unit in Hong Kong after being wounded by monkeys during a recent park visit and contracting a rare and deadly virus spread by primates.

The man, who was previously in good health, was wounded by wild macaque monkeys during a visit to Kam Shan Country Park in late February, according to local health officials. The park is well known for its conservation of wild macaques and features an area that locals call “Monkey Hill” and describe as a macaque kingdom.

On March 21, he was admitted to the hospital with a fever and “decreased conscious level,” health officials reported. As of Wednesday, April 3, he was in the ICU listed in critical condition. Officials reported the man’s case Wednesday after testing of his cerebrospinal fluid revealed the presence of B virus.

B virus, also known as herpes B virus or herpesvirus simiae, is a common infection in macaques, usually causing asymptomatic or mild disease. Infections in humans are extremely rare, but when they occur, they usually come from macaque encounters and are often severe and deadly. The infection can start out a lot like the flu, but the virus can move to the brain and spinal cord, causing brain damage, nerve damage, and death. The US Centers for Disease Control and Prevention estimates that about 70 percent of untreated infections in humans are fatal.

Despite the presence of macaques around Hong Kong, the man’s case is the first known B virus infection documented there. The virus was discovered in 1932, and since then only 50 human infections have been documented as of 2019, the CDC reports. Of those 50 people infected, 21 died. The agency notes that in one case, from 1997, a researcher was infected and died after bodily fluid from an infected monkey splashed into her eye. Still, contracting the virus is rare, even among people exposed to macaques. The CDC reports that there are hundreds of reports of macaque bites and scratches each year in US animal facilities, and infections remain very uncommon.

However low the risk, health officials recommend keeping your distance from wild monkeys and not feeding or touching them. If you are bitten or scratched, wash the wound immediately and seek medical attention.

It only takes one —

Although not quite literally, the Atlantic Ocean is on fire right now.

As of late March, much of the Atlantic Ocean was seeing temperatures far above normal.

Weathermodels.com

The Atlantic hurricane season does not begin for another eight weeks, but we are deep in the heart of hurricane season prediction season.

On Thursday, the most influential of these forecasts was issued by Phil Klotzbach, a hurricane scientist at Colorado State University. To put a fine point on it, Klotzbach and his team foresee an exceptionally busy season in the Atlantic basin, which encompasses the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

“We anticipate that the 2024 Atlantic basin hurricane season will be extremely active,” Klotzbach wrote in his forecast discussion.

The Colorado State forecast calls for 23 named storms, more than 50 percent higher than a typical season of 14.4 named storms; and 11 hurricanes, above a normal total of seven. Additionally, the forecast predicts that the season’s accumulated cyclone energy—a summation of the duration and intensity of storms across the whole basin—will be 70 percent greater than normal. If the forecast is accurate, the year 2024 would rank among the top 10 most active Atlantic hurricane seasons in a century and a half of records.

This forecast is not out of line with other seasonal predictions. Dozens of organizations, from private groups to individual forecasters to media properties, issue these kinds of seasonal predictions. But Colorado State’s is the longest-running and most influential, and its release underscores what is indeed expected to be a very busy season for tropical storms, hurricanes, and major hurricanes.

What’s driving this?

Klotzbach cites two major factors driving the busy year. The primary one is sea surface temperatures in the eastern and central Atlantic, where tropical systems develop. These seas are seeing record warm temperatures for April—indeed, in many places, the Atlantic is already as warm as it typically would be in June. Undoubtedly climate change is a central factor behind this warming.

Warm seas are one precursor to tropical systems, but they are just one condition necessary for a low-pressure system to organize into a tropical depression.

Another is low wind shear, as cross-directional winds can literally shear a storm apart. While it is not possible to forecast wind shear months ahead of a season, the presence of El Niño or La Niña in the Pacific Ocean is a pretty useful indicator.

In this case, there’s more bad news. The present (weak) El Niño in the Pacific is likely to transition into a La Niña by this summer, especially in August or September. That matters because these are typically the most frenetic months for activity, and with a La Niña in place, wind shear is likely to be lower overall in the Atlantic basin.

This is the first of several forecasts Klotzbach will issue for the upcoming season, and although predictions in April typically have lower skill, it is difficult to ignore the signals out there. “While the skill of this prediction is low, our confidence is higher than normal this year for an early April forecast given how hurricane-favorable the large-scale conditions appear to be,” he wrote.

What does this mean?

Most coastal areas along the Atlantic, Caribbean, and Gulf will not be affected by a hurricane in any given year. I live and work in Houston, which is the largest city in the Atlantic basin that regularly sees significant hurricane threats. But even here, in the subtropics, we only see large, direct impacts from a hurricane or tropical storm about every 10 years.

What a busy season does is load the dice. More activity means a greater likelihood that one of those storms will venture closer to where one lives. So the threat of a hurricane is there every year; it’s just that the threat is greater in some years.

There is an old, oft-repeated adage in hurricane forecasting circles: “It only takes one.” This means that even during a slow season if there’s just one hurricane and it hits you, it was a busy hurricane season for you. We experienced this in Houston back in 1983 when the very first named storm of the year, a hurricane named Alicia, made landfall near the city on August 17. There ended up being just four named storms in 1984, but unfortunately for Houston, one of them struck here.

A busy forecast like this doesn’t mean a whole lot for coastal residents. We really need to be prepared every year, knowing our vulnerabilities to a hurricane, knowing when we need to evacuate, where we would go, and what we would need to take.

However, it does have implications for first responders and government organizations tasked with dealing with hurricane aftermath, such as the Federal Emergency Management Agency. Thus, it seems prudent that the recently passed federal budget for fiscal year 2024 tucked $20.3 billion into the agency’s Disaster Relief Fund.

Elon Musk shares “extremely false” allegation of voting fraud by “illegals”

Texas Secretary of State Jane Nelson yesterday issued a statement debunking claims of widespread voter fraud that were amplified by X owner Elon Musk on the social network formerly named Twitter. Election officials in two other states also disputed the “extremely false” information shared by Musk.

Musk is generally a big fan of Texas, but on Tuesday he shared a post by the account “End Wokeness” that claimed, “The number of voters registering without a photo ID is SKYROCKETING in 3 key swing states: Arizona, Texas, and Pennsylvania.” The account claimed there were 1.25 million such registrations in Texas since the beginning of 2024, over 580,000 in Pennsylvania, and over 220,000 in Arizona.

“Extremely concerning,” Musk wrote in a retweet re-X. The End Wokeness post shared by Musk suggested that “illegals” are registering to vote in large numbers by using Social Security numbers that can be obtained for work authorizations. The End Wokeness post has been viewed 63 million times so far, and Musk’s re-post has been viewed 58.2 million times.

Nelson’s statement on the Texas government’s website called the claim “totally inaccurate.” For one thing, the real number of voter registrations is a small fraction of the number claimed in the post shared by Musk, the secretary of state wrote:

It is totally inaccurate that 1.2 million voters have registered to vote in Texas without a photo ID this year. The truth is our voter rolls have increased by 57,711 voters since the beginning of 2024. This is less than the number of people registered in the same timeframe in 2022 (about 65,000) and in 2020 (about 104,000).

“Extremely false”

The Texas Secretary of State office reports having 17,948,242 registered voters for the March 2024 elections, a gain of just under 189,000 voters since November 2023. The total gain over the past 24 months is a little over 764,000.

Pennsylvania’s data shows the state has 8.7 million registered voters and 87,440 voter registrations so far in 2024. Most of those were applications for party changes, while the other 39,877 were new-voter registrations.

Arizona’s total number of registered voters has been declining. While Arizona had 4.28 million registered voters in 2020 and 4.14 million in 2022, the state’s tally in March 2024 was 4,096,260.

Musk’s “Extremely concerning” post got a reply from Maricopa County Recorder Stephen Richer, who called it “extremely false.”

“We haven’t even had that many new registrants TOTAL in 2024 in Arizona,” stated Richer, an elected official and Republican who has been active in calling out election misinformation on X. “And we have fewer than 35,000 registrants (out of 4.1 million registered voters in Arizona) who haven’t provided documented proof of citizenship.”

Musk’s platform has faced plenty of criticism over its moderation of misinformation on elections and other topics. After reports of deep cuts to X’s election integrity team in September 2023, Musk claimed the ex-X employees were “undermining election integrity.”

Subliminal —

Lab experiments suggest gullies on Mars might form when carbon dioxide heats up.

–

Image of a grey-colored slope with channels cut into it.

Mars has a history of liquid water on its surface, including lakes like the one that used to occupy Jezero Crater, which have long since dried up. Ancient water that carried debris—and melted water ice that presently does the same—were also thought to be the only thing driving the formation of gullies spread throughout the Martian landscape. That view may now change thanks to new results that suggest dry ice can also shape the landscape.

It’s sublime

Previously, scientists were convinced that only liquid water shaped gullies on Mars because that’s what happens on Earth. What was not taken into account was sublimation, or the direct transition of a substance from a solid to a gaseous state. Sublimation is how CO2 ice disappears (sometimes water ice experiences this, too).

Frozen carbon dioxide is everywhere on Mars, including in its gullies. When CO2 ice sublimates on one of these gullies, the resulting gas can push debris further down the slope and continue to shape it.

Led by planetary researcher Lonneke Roelofs of Utrecht University in the Netherlands, a team of scientists has found that the sublimation of CO2 ice could have shaped Martian gullies, which might mean the most recent occurrence of liquid water on Mars may have been further back in time than previously thought. That could also mean the window during which life could have emerged and thrived on Mars was possibly smaller.

“Sublimation of CO2 ice, under Martian atmospheric conditions, can fluidize sediment and creates morphologies similar to those observed on Mars,” Roelofs and her colleagues said in a study recently published in Communications Earth & Environment.

Into thin air

Earth and Martian gullies have basically the same morphology. The difference is that we’re certain that liquid water is behind their formation and continuous shaping and re-shaping on Earth. Such activity includes new channels being carved out and more debris being taken to the bottom.

While ancient Mars may have had enough stable liquid water to pull this off, there is not enough on the present surface of Mars to sustain that kind of activity. This is where sublimation comes in. CO2 ice has been observed on the surface of Mars at the same time that material starts flowing.

After examining observations like these, the researchers hypothesized these flows are pushed downward by gas as the frozen carbon dioxide sublimates. Because of the low pressure on Mars, sublimation creates a relatively greater gas flux than it would on Earth—enough power to make fluid motion of material possible.

There are two ways sublimation can be triggered to get these flows moving. When part of a more exposed area of a gully collapses, especially on a steep slope, sediment and other debris that have been warmed by the Sun can fall on CO2 ice in a shadier and cooler area. Heat from the falling material could supply enough energy for the frost to sublimate. Another possibility is that CO2 ice and sediment can break from the gully and fall onto warmer material, which will also trigger sublimation.

Mars in a lab

There is just one problem with these ideas: since humans have not landed on Mars (yet), there are no in situ observations of these phenomena, only images and data beamed back from spacecraft. So, everything is hypothetical. The research team would have to model Martian gullies to watch the action in real time.

To re-create a part of the red planet’s landscape in a lab, Roelofs built a flume in a special environmental chamber that simulated the atmospheric pressure of Mars. It was steep enough for material to move downward and cold enough for CO2 ice to remain stable. But the team also added warmer adjacent slopes to provide heat for sublimation, which would drive movement of debris. They experimented with both scenarios that might happen on Mars: heat coming from beneath the CO2 ice and warm material being poured on top of it. Both produced the kinds of flows that had been hypothesized.

For further evidence that flows driven by sublimation would happen under certain conditions, two further experiments were conducted, one under Earth-like pressures and one without CO2 ice. No flows were produced by either.

“For the first time, these experiments provide direct evidence that CO2 sublimation can fluidize, and sustain, granular flows under Martian atmospheric conditions,” the researchers said in the study.

Because this experiment showed that gullies and systems like them can be shaped by sublimation and not just liquid water, it raises questions about how long Mars had a sufficient supply of liquid water on the surface for any organisms (if they existed at all) to survive. Its period of habitability might have been shorter than it was once thought to be. Does this mean nothing ever lived on Mars? Not necessarily, but Roelofs’ findings could influence how we see planetary habitability in the future.

After AI-generated porn report, Washington Lottery pulls down interactive web app

User says promo site put her uploaded selfie on a topless woman’s body.

A user of the Washington Lottery's

Enlarge / A user of the Washington Lottery’s “Test Drive a Win” website says it used AI to generate (the unredacted version of) this image with her face on a topless body.

The Washington State Lottery has taken down a promotional AI-powered web app after a local mother reported that the site generated an image with her face on the body of a topless woman.

The lottery’s “Test Drive a Win” website was designed to help visitors visualize various dream vacations they could pay for with their theoretical lottery winnings. The site included the ability to upload a headshot that would be integrated into an AI-generated tableau of what you might look like on that vacation.

But Megan (last name not given), a 50-year-old from Olympia suburb Tumwater, told conservative Seattle radio host Jason Rantz that the image of her “swim with the sharks” dream vacation on the website showed her face atop a woman sitting on a bed with her breasts exposed. The background of the AI-generated image seems to show the bed in some sort of aquarium, complete with fish floating through the air and sprawling undersea flora sitting awkwardly behind the pillows.

The corner of the image features the Washington Lottery logo.

“Our tax dollars are paying for that! I was completely shocked. It’s disturbing to say the least,” Megan told Rantz. “I also think whoever was responsible for it should be fired.”

“We don’t want something like this purported event to happen again”

The non-functional

Enlarge / The non-functional “Test Drive a Win” website as it appeared Thursday.

In a statement provided to Ars Technica, a Washington Lottery spokesperson said that the lottery “worked closely with the developers of the AI platform to establish strict parameters to govern image creation.” Despite this, the spokesperson said they were notified earlier this week that “a single user of the AI platform was purportedly provided an image that did not adhere to those guidelines.”

Despite what the spokesperson said were “thousands” of inoffensive images that the site generated in over a month, the spokesperson said that “one purported user is too many and as a result we have shut down the site” as of Tuesday.

The spokesperson did not respond to specific questions about which AI models or third-party vendors may have been used to create the site or on the specific safeguards that were crafted in an attempt to prevent results like the one reported by Megan.

Speaking to Rantz, a lottery spokesperson said the organization had “agreed to a comprehensive set of rules” for the site’s AI images, “including that people in images be fully clothed.” Following the report of the topless image, the spokesperson said they “had the developers check all the parameters for the platform.” And while they were “comfortable with the settings,” the spokesperson told Rantz they “chose to take down the site out of an abundance of caution, as we don’t want something like this purported event to happen again.”

Not a quick fix?

On his radio show, Rantz expressed surprise that the lottery couldn’t keep the site operational after rejiggering the AI’s safety settings. “In my head I was thinking, well, presumably once they heard about this they went back to the backend guidelines and just made sure it said, ‘Hey, no breasts, no full-frontal nudity,’ those kinds of things, and then they fixed it, and then they went on with their day,” Rantz said.

But it might not be that simple to effectively rein in the endless variety of visual output an AI model can generate. While models like Stable Diffusion and DALL-E have filters in place to prevent the generation of sexual or violent images, researchers have found that those models still responded to problematic prompts by generating images that were judged as “unsafe” by an image classifier a significant minority of the time. Malicious users can also use prompt-engineering tricks to get around these built-in safeguards when using popular text-based image-generation models.

We’ve seen these kinds of AI image-safety issues blow back on major corporations, too, as when Facebook’s AI sticker generator put weapons in the hands of children’s cartoon characters.

The Washington Lottery’s AI issue comes a week after a report found a New York City government chatbot confabulating incorrect advice about city laws and regulations. “It’s wrong in some areas and we gotta fix it,” New York City Mayor Eric Adams said this week. “Any time you use technology, you need to put it in the real environment to iron out the kinks. You can’t live in a lab. You can’t stay in a lab forever.”

How one journalist found himself targeted by generative AI over a keyfob photo.

If you run a personal or hobby website, getting a copyright notice from a law firm about an image on your site can trigger some fast-acting panic. As someone who has paid to settle a news service-licensing issue before, I can empathize with anybody who wants to make this kind of thing go away.

Which is why a new kind of angle-on-an-angle scheme can seem both obvious to spot and likely effective. Ernie Smith, the prolific, ever-curious writer behind the newsletter Tedium, received a “DMCA Copyright Infringement Notice” in late March from “Commonwealth Legal,” representing the “Intellectual Property division” of Tech4Gods.

The issue was with a photo of a keyfob from legitimate photo service Unsplash used in service of a post about a strange Uber ride Smith once took. As Smith detailed in a Mastodon thread, the purported firm needed him to “add a credit to our client immediately” through a link to Tech4Gods, and said it should be “addressed in the next five business days.” Removing the image “does not conclude the matter,” and should Smith not have taken action, the putative firm would have to “activate” its case, relying on DMCA 512(c) (which, in many readings, actually does grant relief should a website owner, unaware of infringing material, “act expeditiously to remove” said material). The email unhelpfully points to the main page of the Internet Archive so that Smith might review “past usage records.”

A slice of the website for Commonwealth Legal Services, with every word of that phrase, including “for,” called into question.

Commonwealth Legal Services

There are quite a few issues with Commonwealth Legal’s request, as detailed by Smith and 404 Media. Chief among them is that Commonwealth Legal, a firm theoretically based in Arizona (which is not a commonwealth), almost certainly does not exist. Despite the 2018 copyright displayed on the site, the firm’s website domain was seemingly registered on March 1, 2024, with a Canadian IP location. The address on the firm’s site leads to a location that, to say the least, does not match the “fourth floor” indicated on the website.

While the law firm’s website is stuffed full of stock images, so are many websites for professional services. The real tell is the site’s list of attorneys, most of which, as 404 Media puts it, have “vacant, thousand-yard stares” common to AI-generated faces. AI detection firm Reality Defender told 404 Media that his service spotted AI generation in every attorneys’ image, “most likely by a Generative Adversarial Network (GAN) model.”

Then there are the attorneys’ bios, which offer surface-level competence underpinned by bizarre setups. Five of the 12 supposedly come from acclaimed law schools at Harvard, Yale, Stanford, and University of Chicago. The other seven seem to have graduated from the top five results you might get for “Arizona Law School.” Sarah Walker has a practice based on “Copyright Violation and Judicial Criminal Proceedings,” a quite uncommon pairing. Sometimes she is “upholding the rights of artists,” but she can also “handle high-stakes criminal cases.” Walker, it seems, couldn’t pick just one track at Yale Law School.

Why would someone go to the trouble of making a law firm out of NameCheap, stock art, and AI images (and seemingly copy) to send quasi-legal demands to site owners? Backlinks, that’s why. Backlinks are links from a site that Google (or others, but almost always Google) holds in high esteem to a site trying to rank up. Whether spammed, traded, generated, or demanded through a fake firm, backlinks power the search engine optimization (SEO) gray, to very dark gray, market. For all their touted algorithmic (and now AI) prowess, search engines have always had a hard time gauging backlink quality and context, so some site owners still buy backlinks.

The owner of Tech4Gods told 404 Media’s Jason Koebler that he did buy backlinks for his gadget review site (with “AI writing assistants”). He disclaimed owning the disputed image or any images and made vague suggestions that a disgruntled former contractor may be trying to poison his ranking with spam links.

Asked by Ars if he had heard back from “Commonwealth Legal” now that five business days were up, Ernie Smith tells Ars: “No, alas.”

Unleash the beast: High Performance Cycle’s electric mountain bike

I found myself in the air long enough to give some thought to how I could land while remaining atop the bicycle I had been riding the instant before I hit the jump. Based on similar experiences while skiing, I immediately recognized that this invariably meant very bad things. A few seconds later, as I was brushing dirt out of the abrasions I had just picked up, I contemplated where I had gone wrong.

Once again, I had misunderstood HPC’s Trailblazer e-mountain bike. Doing so had become a feature of the time I spent using the bike.

The Trailblazer looks like a solid, hefty beast of a bike (that’s not an insult—I got compliments on its looks while taking a train to some trails). It’s covered with components that are likely to be unfamiliar to people who know the default sets that come with bikes from large manufacturers. But if you do some research on the components, you realize that the Trailblazer was specced by someone with deep knowledge and fairly particular tastes. And the ride the bike provided has some surprisingly subtle qualities that took me a while to adjust to.

Spare parts

High Performance Cycles offers two models of Trailblazer, the base and the Pro, and both have the same carbon fiber frame. They differ almost entirely based on their components, with the Pro having mostly top-of-the-line material befitting its $9,000 price tag and the base model costing $6,400 for very-good-but-still-a-step-down level components. You can increase the price of either by purchasing more capacious batteries, faster chargers, lights, or even an internal geared hub. (Note that the company has just updated the specs for 2024.)

You can also pay to boost the motor to one capable of speeds that will make you a danger to yourself and others, which will also make the bike illegal to use on anything but private property. Let’s get one thing out of the way here: Making an e-bike that can reach 65 km/hr (40 mph), as some Trailblazer configurations can, is a mistake. But HPC sent me the low-end model that behaved as a standard Class 1 e-bike, with a maximum speed of 32 km/hr (20 mph), so that’s what this review is about.

The suspension system from DVO.

Most of the components you’ll find on mountain bike frames come from just a handful of manufacturers. And HPC relies on some of them (notably SRAM drivetrains). But smaller design companies stay afloat through a combination of replacements for broken parts, tempting people with upgrades, or offering some specific features that aren’t well-served by the more generic designs of major manufacturers. The Trailblazer leans heavily into those.

For example, the tires come from Kenda and have a reputation for great grip at the expense of high rolling resistance—a drawback that matters less when you have an electric assist. The forks and shocks come from a company called DVO and have an adjustment that, based on what I’ve read, should help compensate for the added weight of the hardware. Bafang, which provides the motor, isn’t a household name, but it’s a major player in electrified cycling. I’d already identified the WTB Volt as a highly rated saddle and was pleased to find one on the bike to try out. I could go through the rest of the bike’s specs and say similar things about the other components.

I ended up liking the WTB seat a great deal.

Overall, the parts list felt quirky, and it might give someone who’s expecting big names some pause. But every component I looked into had some features that made it a good (or at least interesting) choice for an e-mountain bike.

Google sues two crypto app makers over allegedly vast “pig butchering” scheme

Google has sued two app developers based in China over an alleged scheme targeting 100,000 users globally over four years with at least 87 fraudulent cryptocurrency and other investor apps distributed through the Play Store.

The tech giant alleged that scammers lured victims with “promises of high returns” from “seemingly legitimate” apps offering investment opportunities in cryptocurrencies and other products. Commonly known as “pig-butchering schemes,” these scams displayed fake returns on investments, but when users went to withdraw the funds, they discovered they could not.

In some cases, Google alleged, developers would “double down on the scheme by requesting various fees and other payments from victims that were supposedly necessary for the victims to recover their principal investments and purported gains.”

Google accused the app developers—Yunfeng Sun (also known as “Alphonse Sun”) and Hongnam Cheung (also known as “Zhang Hongnim” and “Stanford Fischer”)—of conspiring to commit “hundreds of acts of wire fraud” to further “an unlawful pattern of racketeering activity” that siphoned up to $75,000 from each user successfully scammed.

Google was able to piece together the elaborate alleged scheme because the developers used a wide array of Google products and services to target victims, Google said, including Google Play, Voice, Workspace, and YouTube, breaching each one’s terms of service. Perhaps most notably, the Google Play Store’s developer program policies “forbid developers to upload to Google Play ‘apps that expose users to deceptive or harmful financial products and services,’ including harmful products and services ‘related to the management or investment of money and cryptocurrencies.'”

In addition to harming Google consumers, Google claimed that each product and service’s reputation would continue to be harmed unless the US district court in New York ordered a permanent injunction stopping developers from using any Google products or services.

“By using Google Play to conduct their fraud scheme,” scammers “have threatened the integrity of Google Play and the user experience,” Google alleged. “By using other Google products to support their scheme,” the scammers “also threaten the safety and integrity of those other products, including YouTube, Workspace, and Google Voice.”

Google’s lawsuit is the company’s most recent attempt to block fraudsters from targeting Google products by suing individuals directly, Bloomberg noted. Last year, Google sued five people accused of distributing a fake Bard AI chatbot that instead downloaded malware to Google users’ devices, Bloomberg reported.

How did the alleged Google Play scams work?

Google said that the accused developers “varied their approach from app to app” when allegedly trying to scam users out of thousands of dollars but primarily relied on three methods to lure victims.

The first method relied on sending text messages using Google Voice—such as “I am Sophia, do you remember me?” or “I miss you all the time, how are your parents Mike?”—”to convince the targeted victims that they were sent to the wrong number.” From there, the scammers would apparently establish “friendships” or “romantic relationships” with victims before moving the conversation to apps like WhatsApp, where they would “offer to guide the victim through the investment process, often reassuring the victim of any doubts they had about the apps.” These supposed friends, Google claimed, would “then disappear once the victim tried to withdraw funds.”

Another strategy allegedly employed by scammers relied on videos posted to platforms like YouTube, where fake investment opportunities would be promoted, promising “rates of return” as high as “two percent daily.”

The third tactic, Google said, pushed bogus affiliate marketing campaigns, promising users commissions for “signing up additional users.” These apps, Google claimed, were advertised on social media as “a guaranteed and easy way to earn money.”

Once a victim was drawn into using one of the fraudulent apps, “user interfaces sought to convince victims that they were maintaining balances on the app and that they were earning ‘returns’ on their investments,” Google said.

Occasionally, users would be allowed to withdraw small amounts, convincing them that it was safe to invest more money, but “later attempts to withdraw purported returns simply did not work.” And sometimes the scammers would “bilk” victims out of “even more money,” Google said, by requesting additional funds be submitted to make a withdrawal.

“Some demands” for additional funds, Google found, asked for anywhere “from 10 to 30 percent to cover purported commissions and/or taxes.” Victims, of course, “still did not receive their withdrawal requests even after these additional fees were paid,” Google said.

Which apps were removed from the Play Store?

Google tried to remove apps as soon as they were discovered to be fraudulent, but Google claimed that scammers concocted new aliases and infrastructure to “obfuscate their connection to suspended fraudulent apps.” Because scammers relied on so many different Google services, Google was able to connect the scheme to the accused developers through various business records.

Fraudulent apps named in the complaint include fake cryptocurrency exchanges called TionRT and SkypeWallet. To make the exchanges appear legitimate, scammers put out press releases on newswire services and created YouTube videos likely relying on actors to portray company leadership.

In one YouTube video promoting SkypeWallet, the supposed co-founder of Skype Coin uses the name “Romser Bennett,” which is the same name used for the supposed founder of another fraudulent app called OTCAI2.0, Google said. In each video, a completely different presumed hired actor plays the part of “Romser Bennett.” In other videos, Google found the exact same actor plays an engineer named “Rodriguez” for one app and a technical leader named “William Bryant” for another app.

Another fraudulent app that was flagged by Google was called the Starlight app. Promoted on TikTok and Instagram, Google said, that app promised “that users could earn commissions by simply watching videos.”

The Starlight app was downloaded approximately 23,000 times and seemingly primarily targeted users in Ghana, allegedly scamming at least 6,000 Ghanian users out of initial investment capital that they were told was required before they could start earning money on the app.

Across all 87 fraudulent apps that Google has removed, Google estimated that approximately 100,000 users were victimized, including approximately 8,700 in the United States.

Currently, Google is not aware of any live apps in the Play Store connected to the alleged scheme, the complaint said, but scammers intent on furthering the scheme “will continue to harm Google and Google Play users” without a permanent injunction, Google warned.

It’s a past-due reckoning for French microbiologist Didier Raoult, critics say.

A scientific journal published by Elsevier has reportedly posted a stunning 101 expressions of concern on studies connected to Didier Raoult, a disgraced French microbiologist who gained international prominence amid the pandemic by promoting, with little evidence, that the malaria drug hydroxychloroquine could treat COVID-19—a claim that has now been firmly debunked.

According to Retraction Watch, the journal New Microbes and New Infections posted 101 expressions of concern on Raoult’s works recently, including a 2023 study that drew sharp criticism. The study involved giving hydroxychloroquine to tens of thousands of COVID-19 patients after data indicated that it wasn’t effective and the French government rescinded permission for its use against COVID-19. An op-ed in the major French newspaper Le Monde described the study as “the largest ‘wild’ therapeutic trial known to date.”

The expressions of concern also come as Raoult saw his tenth study retracted, Retraction Watch noted.

While Raoult’s unfounded claims about hydroxychloroquine drew initial attention to his COVID-19-related work—with critics quickly noting flaws and weaknesses in his studies—his high-profile claims led critics and sleuths to dive deeper into his extensive publication record. There, they claim they found evidence of long-standing and egregious ethics violations, which were recently laid out in an investigative report by Science Magazine.

Essentially, critics claim Raoult and the institute that he led until 2021, the Hospital Institute of Marseille Mediterranean Infection (IHU), conducted hundreds of studies on humans without appropriate ethical approval or oversight or adequate consent from all participants, the Science investigation found. The IHU work spanned a wide variety of research topics, which involved collecting a variety of biological samples from patients, including vaginal swabs, feces, blood, urine, and breast milk.

However, critics noted 248 IHU studies that reused the same ethical approval code, “09-022,” despite being very different studies that included different kinds of sampling. The critics claim that the studies required separate ethical approvals and additional oversight. They also found that at least 17 studies relied on vulnerable populations, including refugees and people living in homeless shelters, raising serious questions about consent. Some of the studies were also conducted in African countries, where evidence of local ethical approval was either absent or incomplete.

Raoult told the magazine that his research groups had the appropriate ethical approval and said that his critics, whom he described as stalkers and cyber harassers, did not understand how French biomedical laws work.

In Elsevier’s expressions of concern and a linked “Publisher’s Note” from November, the publisher said that the concern was over “the articles’ adherence to Elsevier’s publishing ethics policies and the appropriate conduct of research involving human participants.” Elsevier is still investigating the matter but indicated that the expressions of concern are added “if it is deemed that there is a particular need to alert readers to serious concerns while [the] investigation is ongoing.”

Raoult has had nearly 50 studies likewise flagged over ethical concerns in PLOS journals, Retraction Watch noted. The latest of his studies to be retracted was in the journal Scientific Reports, with the editors there also stating it was due to a lack of ethical oversight. “The paper cites approval from an institutional ethics committee in France, but samples used in this study were also sourced from Algeria, Saudi Arabia, and Niger,” the retraction notice says. “The Authors were not able to provide documentation of approval from ethics committees in these countries or of compliance with local regulations regarding the use of such samples in research.”

Raoult is currently under criminal investigation in France.
