from the pushing-the-jail-door-open dept.

The ubiquitous phone feature has powered a surveillance technique used to catch suspected kidnappers and pedophiles. It's also fueled fears of a 'privacy nightmare' at a time when abortion is criminalized:

The alleged pedophile "LuvEmYoung" had worked to stay anonymous in the chatrooms where he bragged about sexually abusing children. A criminal affidavit said he covered his tracks by using TeleGuard, an encrypted Swiss messaging app, to share a video of himself last month with a sleeping 4-year-old boy.

But the FBI had a new strategy. A foreign law enforcement officer got TeleGuard to hand over a small string of code the company had used to send push alerts — the pop-up notifications that announce instant messages and news updates — to the suspect's phone.

An FBI agent then got Google to quickly hand over a list of email addresses this month linked to that code, known as a "push token," and traced one account to a man in Toledo, an affidavit shows. The man, Michael Aspinwall, was charged with sexual exploitation of minors and distribution of child pornography and arrested within a week of the Google request.

The breakthrough relied on a little-known quirk of push alerts, a basic staple of modern phones: Those tokens can be used to identify users and are stored on servers run by Apple and Google, which can hand them over at law enforcement's request.

[...] The data has become prized evidence for federal investigators, who have used push tokens in at least four cases across the country to arrest suspects in cases related to child sexual abuse material and a kidnapping that led to murder, according to a Washington Post review of court records. And law enforcement officials have defended the technique by saying they use court-authorized legal processes that give officers a vital tool they need to hunt down criminals.

Arthur T Knackerbracket has processed the following story:

Belgian beer brewer Duvel says a ransomware attack has brought its facility to a standstill while its IT team works to remediate the damage.

Spokesperson Ellen Aarts had a statement on tap for local media on Wednesday: "At 0130 last night, the alarms went off in Duvel's IT department because ransomware had been detected. Production was therefore immediately stopped. It is not yet known when it could start again. We hope today or tomorrow.

"Our IT department immediately intervened and is currently still mapping everything out. They are looking for a solution as quickly as possible."

[...] Other manufacturing organizations hit by ransomware often aren't so lucky and any kind of downtime can be operationally and financially damaging.

It's why the industry is such a common target for ransomware miscreants since they know that theoretically, manufacturers are more motivated to pay ransoms quickly, minimizing costly downtime.

A 2.9-ton cargo pallet, once used for a critical battery upgrade mission on the International Space Station (ISS), is now approaching the end of its journey and is expected to reenter the Earth’s atmosphere in the coming days.

The pallet, tossed from the ISS in March 2021 by the trusty Canadarm2, is facing imminent destruction in Earth’s atmosphere three years after serving its purpose in a major battery replacement project on the station. According to Harvard-Smithsonian astronomer Jonathan McDowell, the pallet “will not totally burn up on reentry—about half a ton of fragments will likely hit the Earth’s surface,” McDowell noted on X.

It’s the end of the orbital road for the heaviest piece of ISS space trash, which has been gradually falling towards Earth like a fly getting sucked up in a kitchen drain. The expected reentry of the cargo pallet into Earth’s atmosphere is between March 8 at 7:30 a.m. ET and March 9 at 3:30 a.m. ET, according to McDowell. The exact location of reentry is not known.

Arthur T Knackerbracket has processed the following story:

Veterinary scientists seem to have unraveled a mystery about why certain dogs simply can’t ever get enough to eat. In research out this week, they found evidence that a common mutation in Labrador retrievers causes them to experience greater hunger than usual while also reducing their metabolic rate, both of which make the dogs predisposed to obesity. The findings might help better understand and treat obesity in both dogs and their owners.

Labradors are one of the most popular dog breeds in the world, treasured for their playful energy and their adeptness as a working dog (they’re often used as service dogs). But while labs do live relatively long lives—about 13 years on average—they’re also known to have a ravenous appetite and accordingly high rates of obesity.

Labs aren’t alone in their plight: Much like humans, dogs in general are experiencing higher rates of obesity. University of Cambridge scientist Eleanor Raffan has been working to unpack the genetics of obesity and metabolic disease in dogs. Her team has especially focused on the Labrador retriever, given its reputation for obesity, and its close relative the flat-coated retriever.

Roku customers are threatening to stop using, or to even dispose of, their low-priced TVs and streaming gadgets after the company appears to be locking devices for people who don't conform to the recently updated terms of service (ToS).

This month, users on Roku's support forums reported suddenly seeing a message when turning on their Roku TV or streaming device reading: "We've made an important update: We’ve updated our Dispute Resolution Terms. Select ‘Agree’ to agree to these updated Terms and to continue enjoying our products and services. Press * to view these updated Terms." A large button reading "Agree" follows. The pop-up doesn't offer a way to disagree, and users are unable to use their device unless they hit agree.

Customers have left pages of complaints on Roku's forum. One user going by "rickstanford" said they were "FURIOUS!!!!" and expressed interest in sending their reported six Roku devices back to the company since "apparently I don't own them despite spending hundreds of dollars on them."

Bruce Perens is working on licensing for a new, post-Open Source era to take open source licensing past the apparent stalling point it has reached on its way towards software freedom. As he noted earlier, current licenses are not meeting that goal and businesses have either found loophole or just plain been allowed to ignore the licensing. A move more towards a contract is needed.

At the link below is the first draft of the Post-Open License. This is not yet the product of a qualified attorney, and you shouldn't apply it to your own work yet. There isn't context for this license yet, so some things won't make sense: for example the license is administered by an entity called the "POST-OPEN ADMINISTRATION" and I haven't figured out how to structure that organization so that people can trust it. There are probably also terms I can't get away with legally, this awaits work with a lawyer.

Because the license attempts to handle very many problems that have arisen with Open Source licensing, it's big. It's approaching the size of AGPL3, which I guess is a metric for a relatively modern license, since AGPL3 is now 17 years old

The draft license is quite long since it covers quite a few scenarios.

https://arstechnica.com/tech-policy/2024/03/microsoft-accused-of-selling-ai-tool-that-spews-violent-sexual-images-to-kids/

Microsoft's AI text-to-image generator, Copilot Designer, appears to be heavily filtering outputs after a Microsoft engineer, Shane Jones, warned that Microsoft has ignored warnings that the tool randomly creates violent and sexual imagery, CNBC reported.

Jones told CNBC that he repeatedly warned Microsoft of the alarming content he was seeing while volunteering in red-teaming efforts to test the tool's vulnerabilities. Microsoft failed to take the tool down or implement safeguards in response, Jones said, or even post disclosures to change the product's rating to mature in the Android store.

[...] Bloomberg also reviewed Jones' letter and reported that Jones told the FTC that while Copilot Designer is currently marketed as safe for kids, it's randomly generating an "inappropriate, sexually objectified image of a woman in some of the pictures it creates." And it can also be used to generate "harmful content in a variety of other categories, including: political bias, underage drinking and drug use, misuse of corporate trademarks and copyrights, conspiracy theories, and religion to name a few."

[...] Jones' tests also found that Copilot Designer would easily violate copyrights, producing images of Disney characters, including Mickey Mouse or Snow White. Most problematically, Jones could politicize Disney characters with the tool, generating images of Frozen's main character, Elsa, in the Gaza Strip or "wearing the military uniform of the Israel Defense Forces."

Ars was able to generate interpretations of Snow White, but Copilot Designer rejected multiple prompts politicizing Elsa.

If Microsoft has updated the automated content filters, it's likely due to Jones protesting his employer's decisions. [...] Jones has suggested that Microsoft would need to substantially invest in its safety team to put in place the protections he'd like to see. He reported that the Copilot team is already buried by complaints, receiving "more than 1,000 product feedback messages every day." Because of this alleged understaffing, Microsoft is currently only addressing "the most egregious issues," Jones told CNBC.

https://phys.org/news/2024-03-threatened-homeland-feral-mexican-parrots.html

During a walk through the Huntington Botanical Gardens with her mother one morning, Brenda Ramirez was alarmed by the sudden squawks, warbles, and screeches of troops of parrots flying overhead at great speed in tight, precise formations.

"I asked my mom what they were," Ramirez recalled of that day 14 years ago. "She said, 'Mija, they are just like the parrots from Mexico we've seen in zoos, except for one thing: They are free flying and breed in the trees along our city streets.'"

Ramirez was entranced by this fleeting glimpse of adaptation by tropical species in one of the world's greatest asphalt jungles.

Now, at 27, she leads a team of investigators at the Free Flying Los Angeles Parrot Project based in Occidental College's Moore Laboratory of Zoology, which aims to resolve a biological puzzle: How did red-crowned and lilac-crowned parrots establish local urban breeding populations via the pet trade from Mexico, where both species are on the brink of extinction?

A potential answer is that Southern California cities have only in the last 100 years provided these sister species with a resource untapped by native birds: the fruits and flowers of exotic trees used for landscaping, according to the team's new report in the journal Diversity and Distributions.

Their findings add to a growing body of evidence that some introduced species including these feral parrots can experience rapid niche shifts beyond what appears to be possible in the forested regions of northern Mexico they evolved in.

[...] "Artificial irrigation may close the gap between native and introduced climates," the study suggests, "allowing more year-round vegetation in Southern California cities than expected given its natural precipitation levels."

That "urban oasis effect" created by sprinkler watering systems "could partly explain why introduced parrots do not seem to be spreading beyond urban centers," it says. "Their intelligence and behavioral plasticity might further allow them to adapt to urban life."

The look of Southern California's green canopies has changed significantly since the 1950s and '60s, when developers turned up their noses at native oaks and sycamores. They chose instead to landscape their subdivisions, apartment complexes, business parks, shopping centers and roadways with nonnative trees, including sweet gums, camphor, carrotwood, fig, and ficus trees—all favored by parrots.

[...] Red-crowned parrots, whose home range is restricted to the lowlands of northeast Mexico, were first recorded in the Los Angeles area in 1963. Since then, the population has swelled to more than 3,000 birds, the study says.

The number of lilac-crowned parrots, which are endemic to tropical lowlands in west Mexico and became established locally in the 1980s, is about 800 birds.

Given that both species are considered endangered in their home ranges in Mexico due to habitat loss and trapping for the pet trade, local established flocks have become prized for their conservation potential.

https://arstechnica.com/gaming/2024/03/switch-emulator-makers-agree-to-pay-2-4-million-to-settle-nintendo-lawsuit/

The makers of Switch emulator Yuzu say they will "consent to judgment in favor of Nintendo" to settle a major lawsuit filed by the console maker last week.

In a series of filings posted by the court Monday, the Yuzu developers agreed to pay $2.4 million in "monetary relief" and to cease "offering to the public, providing, marketing, advertising, promoting, selling, testing, hosting, cloning, distributing, or otherwise trafficking in Yuzu or any source code or features of Yuzu."

[...] ending "effective immediately," along with support for 3DS emulator Citra (which shares many of the same developers)

[...] The proposed final judgment, which still has to be agreed to by the judge in the case, fully accepts Nintendo's stated position that "Yuzu is primarily designed to circumvent [Nintendo's copy protection] and play Nintendo Switch games" by "using unauthorized copies of Nintendo Switch cryptographic keys."

[...] While that admission doesn't technically account for Yuzu's ability to run a long list of Switch homebrew programs, proving that such homebrew was a significant part of the "ordinary course" of the average Yuzu user's experience may have been an uphill battle in court. Nintendo argued in its lawsuit that "the vast majority of Yuzu users are using Yuzu to play downloaded pirated games in Yuzu," a fact that could have played against the emulator maker at trial even if non-infringing uses for the emulator do exist.

[...] While emulator programs are generally protected by US legal precedents protecting reverse engineering, console makers could bring similar DMCA actions against certain emulators that rely on the use of cryptographic keys to break copy protection. But many emulator makers feel that such hardball lawsuits are less likely to be brought against emulators for defunct systems that are no longer selling new hardware or software in significant numbers.

[...] Nintendo's legal department has established a track record of zealously defending its copyrighted works by going after fangames, ROM distribution sites, and hardware modders in the past. While direct legal action against emulator makers has been less common for Nintendo, the company did send a letter to Valve to prevent Wii/Gamecube emulator Dolphin from appearing on Steam last year.

Science, or New Age Apocalyptics? You decide.

In 2007, a group of researchers, led by a nuclear physicist named Richard Firestone, announced an astonishing discovery. They had uncovered evidence, they said, that 12,900 years ago, a comet — or possibly a whole fleet of comets — struck Earth and changed the course of history. For the preceding two and a half million years, through the Pleistocene Epoch, the planet's climate fluctuated between frozen stretches, called glacials, and warm interglacials. At that time, Earth was warming again, and the ice sheets that covered much of North America, Europe and Asia were in retreat. Mammoths, steppe bison, wild horses and other enormous mammals still wandered the Americas, pursued by bands of humans wielding spears with fluted stone blades. Suddenly, somewhere over the Upper Midwest — an explosion.

[...] This cometary origin story, with its mix of ancient humans, vanished megafauna and global cataclysm, quickly spread beyond the confines of scientific journals. Media outlets around the world covered the Younger Dryas impact hypothesis. It has been the subject of two more books and multiple documentaries, including one produced by PBS NOVA. Joe Rogan has discussed the hypothesis a dozen times on his podcast, and it provided the scientific underpinnings for Netflix's 2022 hit series "Ancient Apocalypse." But even as the hypothesis wormed its way into the public imagination, an important question persisted: Was any of it true?

[...] As they tried to replicate the Firestone team's findings, the skeptics noticed numerous odd details that seemed to hover around the hypothesis. There was, for example, "The Cycle of Cosmic Catastrophes," which came out just before the Proceedings of the National Academy of Sciences study. The book's publisher was a division of Inner Traditions, which, according to its website, is "devoted exclusively to the subjects of spirituality, the occult, ancient mysteries, new science, holistic health and natural medicine." The book, written by West and Firestone, intersperses a breathless account of their work with the "astonishingly similar stories" of floods and celestial conflagrations from dozens of ancient cultures, including the tale of the "Long-Tailed-Heavenly-Climbing-Star," attributed to the Ojibwa. "It clearly wasn't a science book," says Jennifer Marlon, a paleoecologist at Yale who read the book soon after seeing the PNAS study. "I just thought, Well, this is kind of silly."

[...] The widespread interest in the impact hypothesis outside academia can appear difficult to understand, says Tristan Sturm, a geographer at Queen's University Belfast, who studies apocalyptic narratives and conspiracy theories. "Archaeology is not a superpopular topic," he points out. Nor does grasping the truth about the impact hypothesis have obvious importance for the average person.

[...] More broadly, the hypothesis' fringe status appeals to those who are experiencing what Sturm calls "conspiracism," the reflexive distrust of authority figures, including politicians, journalists and, increasingly, scientists. A tendency toward conspiracism does not necessarily mean someone subscribes to actual conspiracy theories, Sturm says; rather, it is a gap in the epistemological immune system through which conspiracy theories enter.

[...] In the course of publishing this work, though, members of the Comet Research Group say they have encountered signs that their opponents have moved from simply voicing skepticism to actively trying to suppress their research. Despite receiving several favorable peer reviews on a paper submitted to a scientific journal, group leaders told me, the journal's editor summarily rejected it. In response, they started their own scientific journal, called Airbursts and Cratering Impacts, whose editors include West and two other Comet Research Group members. All three assured me that submissions to the journal are peer-reviewed according to the usual best practices; so far, the journal has published six papers from the group.

I began to wonder if, in trying to draw connections between the various oddities that swirled around the Comet Research Group, Boslough was himself falling into a kind of conspiratorial thinking. "I have indeed asked myself that question," he told me. But after careful consideration, he had concluded that he was not.

Comet Research Group members predicted to me that skeptics like Boslough could never be persuaded, only waited out. "You know that old saying," West told me. " 'Science advances one funeral at a time.'" During one of my conversations with him, I asked — as I did of nearly everyone I spoke with, on both sides of the issue — whether he ever harbored any doubts. Was there any kind of evidence that might convince him that he was wrong?

In a sense, what West and his collaborators think now hardly matters. The hypothesis has already penetrated deeply, and perhaps indelibly, into the public imagination, seemingly on its way to becoming less a matter of truth than a matter of personal and group identity.

https://arstechnica.com/science/2024/03/producing-more-but-understanding-less-the-risks-of-ai-for-scientific-research/

Last month, we witnessed the viral sensation of several egregiously bad AI-generated figures published in a peer-reviewed article in Frontiers, a reputable scientific journal. Scientists on social media expressed equal parts shock and ridicule at the images, one of which featured a rat with grotesquely large and bizarre genitals.

As Ars Senior Health Reporter Beth Mole reported, looking closer only revealed more flaws, including the labels "dissilced," "Stemm cells," "iollotte sserotgomar," and "dck." Figure 2 was less graphic but equally mangled, rife with nonsense text and baffling images. Ditto for Figure 3, a collage of small circular images densely annotated with gibberish.

[...] While the proliferation of errors is a valid concern, especially in the early days of AI tools like ChatGPT, two researchers argue in a new perspective published in the journal Nature that AI also poses potential long-term epistemic risks to the practice of science.

Molly Crockett is a psychologist at Princeton University who routinely collaborates with researchers from other disciplines in her research into how people learn and make decisions in social situations. Her co-author, Lisa Messeri, is an anthropologist at Yale University whose research focuses on science and technology studies (STS), analyzing the norms and consequences of scientific and technological communities as they forge new fields of knowledge and invention—like AI.

[...] The paper's tagline is "producing more while understanding less," and that is the central message the pair hopes to convey. "The goal of scientific knowledge is to understand the world and all of its complexity, diversity, and expansiveness," Messeri told Ars. "Our concern is that even though we might be writing more and more papers, because they are constrained by what AI can and can't do, in the end, we're really only asking questions and producing a lot of papers that are within AI's capabilities."

[...] One concrete example: My team built a machine learning algorithm to predict moral outrage expressions on Twitter. It works really well. It does as well as showing a tweet to a human and asking, "Is this person outraged or not?" In order to train that algorithm, we showed a bunch of tweets to human participants and asked them to say whether this tweet contained outrage. Because we have that ground truth of human perception, we can be reasonably certain that our tool is doing what we want it to do.

[...] Once you have multiple models interacting which are not interpretable and might be making errors in a systematic way that you are not able to recognize, that's where we start to get into dangerous territory. Legal scholar Jonathan Zittrain has called this concept "intellectual debt": As soon as you have multiple systems interacting in a complex environment, you can very quickly get to a point where there are errors propagating through the system, but you don't know where they originate because each individual system is not interpretable to the scientists.

[...] So much of the discourse around AI pushes this message of inevitability: that AI is here, it is not going away, it's inevitable that this is going to bring us to a bright future and solve all our problems. That message is coming from people who stand to make a lot of money from AI and its uptake all across society, including science. But we decide when and how we are going to use AI tools in our work. This is not inevitable. We just need to be really careful that these tools serve us. We're not saying that they can't. We're just adamant that we need to educate ourselves in the ways that AI introduces epistemic risk to the production of scientific knowledge. Scientists working alone are not going to engineer our way out of those risks.

https://phys.org/news/2024-03-bumblebees-scientists-advanced-social-skills.html

In a groundbreaking discovery, bumblebees have been shown to possess a previously unseen level of cognitive sophistication. A new study, published in Nature, reveals that these fuzzy pollinators can learn complex, multi-step tasks through social interaction, even if they cannot figure them out on their own. This challenges the long-held belief that such advanced social learning is unique to humans, and even hints at the presence of key elements of cumulative culture in these insects.

Led by Dr. Alice Bridges and Professor Lars Chittka , the research team designed a two-step puzzle box requiring bumblebees to perform two distinct actions in sequence to access a sweet reward at the end. Training bees to do this was no easy task, and bees had to be helped along by the addition of an extra reward along the way. This temporary reward was eventually taken away, and bees subsequently had to open the whole box before getting their treat.

Surprisingly, while individual bees struggled to solve the puzzle when starting from scratch, those allowed to observe a trained "demonstrator" bee readily learned the entire sequence—even the first step—while only getting a reward at the end.

This study demonstrates that bumblebees possess a level of social learning previously thought to be exclusive to humans. They can share and acquire behaviors that are beyond their individual cognitive capabilities: an ability thought to underpin the expansive, complex nature of human culture, and one previously thought to be exclusive to us.

Dr. Bridges says, "This is an extremely difficult task for bees. They had to learn two steps to get the reward, with the first behavior in the sequence being unrewarded. We initially needed to train demonstrator bees with a temporary reward included there, highlighting the complexity."

"Yet, other bees learned the whole sequence from social observation of these trained bees, even without ever experiencing the first step's reward. But when we let other bees attempt to open the box without a trained bee to demonstrate the solution, they didn't manage to open any at all."

from the X-née-Twitter dept.

Multiple sites are reporting that the former Twitter (now called X but not that X) executives who were apparently stiffed on severance pay are now suing Elon Musk over the missing severance pay.

Former top executives of Twitter sued Elon Musk on Monday saying he has failed to pay them nearly $130 million after the billionaire took over the social media company and dismissed them.

"Musk doesn't pay his bills, believes the rules don't apply to him, and uses his wealth and power to run roughshod over anyone who disagrees with him," they said in the lawsuit filed in a California federal court.

'Musk vowed a lifetime of revenge': Ex-Twitter execs sue Musk for unpaid severance

The big picture: The former executives claim in the complaint that he fired them soon after he led the takeover of the company now known as X "without reason, then made up fake cause and appointed employees of his various companies to uphold his decision."

• "Musk's refusal to pay Plaintiffs their benefits is part of a larger pattern of refusing to pay Twitter's former employees the benefits and other compensation they are due," alleges the complaint, filed in federal court in San Francisco.

Elon Musk sued by former Twitter executives over severance payments

Parag Agrawal sues Elon Musk: Former Twitter CEO Parag Agrawal and three other ex-executives have suited company boss Elon Musk for $128 million in unpaid severance payments alleging that the billionaire showed "special ire" towards them by publicly vowing to withhold their severance payments of around $200 million. This happened after Elon Musk took over the social media platform in a $44 billion deal in 2022 after which they were ousted from the company, as per the lawsuit filed.

Why is ex-Twitter CEO Parag Agrawal suing Elon Musk?

Elon Musk fired a lot of people after he took over Twitter, but the first ones to go were several of its top executives. Now former CEO Parag Agrawal, former CFO Ned Segal, former chief legal officer Vijaya Gadde, and former general counsel Sean Edgett are suing Musk and the company now known as X, saying they're owed more than $128 million in severance payments, as reported by The Wall Street Journal.

Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being eaten.

It is well known that many inedible species of butterfly have evolved near identical color patterns, which act as warning signals to predators so the butterflies avoid being eaten.

Researchers have now shown that these butterflies have not only evolved similar color patterns, but that they have also evolved similar flight behaviors, which together make a more effective warning signal to predators. The article is published in the journal Proceedings of the National Academy of Sciences.

Using high-speed video footage to record the flight of wild butterflies in South America, researchers at the University of York measured the wing beat frequency and wing angles of 351 butterflies, representing 38 species each belonging to one of 10 distinct color pattern mimicry groups.

Using this dataset they investigated how the flight patterns of butterflies are related to factors such as habitat, wing shape, temperature and which color pattern mimicry group the butterfly belongs to see which elements most heavily affected flight behavior.

Although the species habitat and wing shape were expected to have the greatest influence on flight behavior, the researchers found that in fact the biggest determinant of flight behavior was the color pattern mimicry group a butterfly belonged to.

This means that distantly-related butterflies belonging to the same color pattern mimicry group have more similar flight behavior than closely-related species that display different warning coloration. To a predator, the butterflies would not only look the same through their color patterns, but would also move in the same way.
