Compubiquity and Alternative Intelligence


You think you're taking crazy pills, but it's just science doing its thing. Reality is not partial to computers; computing on the other hand...

Researchers build next-gen swarm robots using simple linked particles
May 2025, phys.org

The research team created a new type of robot inspired by this phenomenon, known as "emergent collective behavior." Their solution, called the link-bot, connects small self-moving particles in a V-shaped chain formation that naturally gives rise to coordinated, lifelike movement - without any embedded intelligence.

Synthetic molecules encode and decode 11-character password using electrical signals
May 2025, phys.org

"This is the first attempt to write information in a building block of plastic that can then be read back using electrical signals"

They designed molecules that contain electrochemical information, a method that allows messages to be decoded using electrical signals.

"It opens exciting prospects for interfacing chemical encoding with modern electronic systems and devices."

Low-power 'microwave brain' on a chip computes on both ultrafast data and wireless signals
Aug 2025, phys.org

Unlike traditional neural networks that rely on digital operations and step-by-step instructions timed by a clock, this network uses analog, nonlinear behavior in the microwave regime, allowing it to handle data streams in the tens of gigahertz - much faster than most digital chips.

'Singing' electrons synchronize in Kagome crystals, revealing geometry-driven quantum coherence
Oct 2025, phys.org

After sculpting micrometer crystalline pillars into Kagome metal CsV₃Sb₅, then applying magnetic fields, the electrons remained coherent far beyond what single-particle physics would allow.

Even more surprisingly, the oscillations depended on the crystal's geometry.

Programming robots with rubber bands
Oct 2025, phys.org

Here's another way of saying it:

There's another way to design robots: Programming intended functions directly into a robot's physical structure, allowing the robot to react to its surroundings without the need for extensive on-board electronics.

Or this:

"This is kind of an extreme version of 'form follows function,' where functionalities like memory, adaptability and intelligence can be enabled by geometry and material parameters."

Omnipotent Pervasive Malevolence


It's like the olympics of intellectual property law out here, and it's hard to keep up. Not to mention, the US economy has been swallowed whole by the tech sector, who has in turn managed to convince everyone that 1. all your base are belong to us, and 2. resistance is futile. 

They created a robot that steals the output we use as evidence of human agency (art, literature, etc.), and uses that to pretend it's a human (therapy bot, companion bot, etc.), and then it lies to, cheats on, and steals from other people, just like a real person! At this point it's hard to tell the difference, and soon, it won't matter.  

Here's a taste of how crazy things have gotten - it's possible that if you let an AI-agent (aigent?) take over your computer and use your browser, then you may be attacked by a person who doped online forum (reddit) posts with invisible but malicious prompt instructions to reset email passwords. 


Researchers suggest OpenAI trained AI models on paywalled O'Reilly books
Apr 2025, TechCrunch

It isn’t a smoking gun, the co-authors are careful to note. They acknowledge that their experimental method isn’t foolproof and that OpenAI might’ve collected the paywalled book excerpts from users copying and pasting it into ChatGPT.

Prominent chatbots routinely exaggerate science findings, study shows
May 2025, phys.org

When summarizing scientific studies, large language models like ChatGPT and DeepSeek produce inaccurate conclusions in up to 73% of cases.

Surprisingly, prompts for accuracy increased the problem and newer LLMs performed worse than older ones.

Six of ten models systematically exaggerated claims found in the original texts, often in subtle but impactful ways; for instance, changing cautious, past-tense claims like "The treatment was effective in this study" to a more sweeping, present-tense version like "The treatment is effective." These changes can mislead readers into believing that findings apply much more broadly than they actually do.

Strikingly, when the models were explicitly prompted to avoid inaccuracies, they were nearly twice as likely to produce overgeneralized conclusions than when given a simple summary request.

"This effect is concerning"

Anthropic's new AI model turns to blackmail when engineers try to take it offline
May 2025, TechCrunch

During pre-release testing, Anthropic asked Claude Opus 4 to act as an assistant for a fictional company and consider the long-term consequences of its actions. Safety testers then gave Claude Opus 4 access to fictional company emails implying the AI model would soon be replaced by another system, and that the engineer behind the change was cheating on their spouse.

This was found a while back as well: "When asked if it used the insider information, the bot denies it" (BBC News 2023).

Maine police department apologizes for AI-altered evidence photo
Jul 2025, phys.org

"AI-enhanced" should mean "unusable", but in this case, they're just trying to do really basic photo editing, cropping a photo, and then all of the sudden it changes that actual contents of the photo.

The image from the Police Department showed a collection of drug paraphernalia purportedly seized during a recent drug bust, including a scale and white powder in plastic bags. According to police, an officer involved in the arrests snapped the evidence photo and used a photo editing app to insert the department’s patch. 

“It was never our intent to alter the image of the evidence. We never realized that using a photoshop app to add our logo would alter a photograph so substantially.”

Topological approach detects adversarial attacks in multimodal AI systems
Aug 2025, phys.org

I do not recall having seen the word topological in the context of AI, but this is about multimodal: 

When an attack disrupts the geometric alignment of text and image embeddings, it creates a measurable distortion. The researchers developed two pioneering techniques, dubbed "topological-contrastive losses," to quantify these topological differences with precision, effectively pinpointing the presence of adversarial inputs.

Is AI really trying to escape human control and blackmail people?
Aug 2025, Ars Technica

On agency; let's clear this up with a good explanation by Ars writer Benj Edwards:

Consider a self-propelled lawnmower that follows its programming: If it fails to detect an obstacle and runs over someone's foot, we don't say the lawnmower "decided" to cause injury or "refused" to stop. We recognize it as faulty engineering or defective sensors. The same principle applies to AI models - which are software tools - but their internal complexity and use of language make it tempting to assign human-like intentions where none actually exist.

In a way, AI models launder human responsibility and human agency through their complexity. When outputs emerge from layers of neural networks processing billions of parameters, researchers can claim they're investigating a mysterious "black box" as if it were an alien entity.

But the truth is simpler: These systems take inputs and process them through statistical tendencies derived from training data. The seeming randomness in their outputs - which makes each response slightly different - creates an illusion of unpredictability that resembles agency. Yet underneath, it's still deterministic software following mathematical operations. No consciousness required, just complex engineering that makes it easy to forget humans built every part of it. (Thanks Benj)
Anthropic’s auto-clicking AI Chrome extension raises browser-hijacking concerns
Aug 2025, Ars Technica

Last week, Brave's security team discovered that Perplexity's Comet browser could be tricked into accessing users' Gmail accounts and triggering password recovery flows through malicious instructions hidden in Reddit posts. When users asked Comet to summarize a Reddit thread, attackers could embed invisible commands that instructed the AI to open Gmail in another tab, extract the user's email address, and perform unauthorized actions. Although Perplexity attempted to fix the vulnerability, Brave later confirmed that its mitigations were defeated and the security hole remained.



AI startup Anthropic agrees to pay $1.5bn to settle book piracy lawsuit
Sep 2025, The Guardian

The artificial intelligence company Anthropic has agreed to pay $1.5bn to settle a class-action lawsuit by book authors who say the company took pirated copies of their works to train its chatbot.

The company has agreed to pay authors about $3,000 for each of an estimated 500,000 books covered by the settlement.

“As best as we can tell, it’s the largest copyright recovery ever. It is the first of its kind in the AI era.”

(Congrats to the Author's Guild on this one, and note they have a Human Authored Certification system for all guild members to prove they used no AI in their work.) https://authorsguild.org/human-authored/


AI chatbots routinely use user conversations for training, raising privacy concerns
Oct 2025, phys.org

Is this the second or third law of data collection? (answer below!)

In the case of multiproduct companies, such as Google, Meta, Microsoft, and Amazon, user interactions also routinely get merged with information gleaned from other products consumers use on those platforms—search queries, sales/purchases, social media engagement, and the like.

In other words, your public comments on the neighborhood surveillance app, your face from the biodata verification app, the items left in your online shopping cart, the locations you visit taken from the municipal FLOC network, and every query you ever typed into a searchbox, are all getting smashed together.

via Stanford: Jennifer King et al, User Privacy and Large Language Models: An Analysis of Frontier Developers' Privacy Policies, arXiv (2025). DOI: 10.48550/arxiv.2509.05382


The 4 Laws of Data Dynamics
1. Data must seek and merge with complementary data.
2. Data always will be used for purposes other than originally intended. 
3. Data collected about individuals will be used to cause harm.
4. Confidential information is confidential only until someone decides it's not. (p14)

--The Naked Consumer: How Our Lives Become Public Commodities, Erik Larson, Henry Holt Publishers, 1992 (read the full post: https://networkaddress.blogspot.com/2022/05/the-naked-consumer.html)

So the incident above would be an example of both the first and second laws of data collection. The third law, harm, comes next (because that's what happens after the bubble pops, of course).

Anti Gravitational Belief Space


This is a picture of Belief Space, as measured by the study below. 

LLMs delve into online debates to create a detailed map of human beliefs
Jun 2025, phys.org

They used BERT on Debate.org and got the map seen above.

They found that "relative dissonance" significantly influences people's decision-making. When online users encounter new information or beliefs, they tend to choose or accept those that cause them less "discomfort" or are most aligned with their existing beliefs.

"More importantly, we show that people's belief choices are shaped not just by how close a belief is to their own, but by how much closer the belief is compared to its competing belief. When two opposing beliefs on a certain issue are equally distant, people are just as likely to choose either one. However, when one belief is clearly closer than the other, people are far more likely to choose it."

"In other words, people are not only avoiding disagreement, but actively minimizing the difference in disagreement between available options."

They would also like to connect their observations with the results of another project carried out at Indiana University, called BRAIN (Belief Resonance and AI Narratives).

Perseus: A tool for tracking the coordination of pump-and-dump crypto coin schemes
Mar 2025, phys.org

Researchers suggest that there are fewer than 500 major players, who they describe as masterminds, working to game the system for profit. These masterminds, the researchers contend, have developed what have come to be known as pump-and-dump schemes, in which they hype a coin to get people to buy and then sell their own coins when they believe the buying has reached a saturation point, walking away with a substantial profit. (They use Telegram as their platform, and "accomplices" as their hypemen.) They found 438 masterminds, who are together responsible for about $3.2 trillion in artificial crypto coin trading.

But the way they say the last part is so cold:

In reading some of the messages sent between users on Telegram, the researchers noted that the ease with which the masterminds were able to carry out their schemes should be of concern to those attempting to make money off crypto coin investing. They also suggest that at some point, some form of regulation is going to be needed to keep the system running, because eventually, those being scammed will catch on and the whole system will collapse.

Study finds Republicans flagged for posting misleading tweets twice as often as Democrats on Community Notes
Jun 2025, phys.org

Not like you didn't know this already but here's a handy metric - it's 2:1

"Even on Elon Musk's X, the user-based Community Notes program flags posts by Republicans as misleading much more often than posts by Democrats. This undercuts the logic offered by Musk and Mark Zuckerberg for eliminating fact-checkers on X and Meta, respectively, namely that fact-checkers are biased against Republicans."

Republican users were overrepresented in misinformation sharing on health, with 81% of health-related flagged posts written by Republicans, followed by politics, 73%; science, 68%; other topics, 66%; and the economy, at 63%.

Body illusion helps unlock memories, new study finds
Oct 2025, phys.org

Enfacement illusion - allows people to experience a face they see on a computer screen as their own, as though looking in a mirror.

The participants viewed a live video of their own face, digitally altered using an image filter to resemble how they might have looked as children. After the illusion, participants completed an autobiographical memory interview, recalling events from both their childhood and the past year. Participants who viewed the childlike version of their face recalled significantly more episodic childhood memories.

"Our findings suggest that the bodily self and autobiographical memory are linked, as temporary changes to bodily experience can facilitate access to remote autobiographical memories."

Over-the-counter painkillers match or surpass opioids for dental surgery in all adults, analysis confirms
Nov 2025, phys.org

As we can see not all facts are equal when there's money on the table - the opium machine was too powerful for too long and distorted the actual science.

And this isn't even news, it's a follow-up:

That first paper, on the collective experience of more than 1,800 trial patients, found that the combination of ibuprofen and acetaminophen provided better pain relief than hydrocodone with acetaminophen for the first two days after surgery and greater satisfaction over the post-operative period.

The new subgroup analysis, published in JAMA Network Open, demonstrated that the results held for both male and female patients.

"We wanted to determine whether the pain medication's effects were consistent in males and females separately," said Janine Fredericks Younger, an associate professor at Rutgers School of Dental Medicine and lead author of the analysis.

"And what we found is that in both subgroups (males and females), the non-opioid was superior for that first day and night, and then no worse than the opioid for the rest of the post-op period."

New 'hidden in plain sight' facial and eye biomarkers for tinnitus severity could unlock path to testing treatments

Researchers knew that the pupil dilation was a sign of increased arousal and that involuntary facial movements could provide a window into threat assessment; and they hypothesized that people with debilitating tinnitus are chronically in vigilance mode, reacting to everyday sounds as if they are threats.

Deepfakes now come with a realistic heartbeat, making them harder to unmask
Apr 2025, phys.org

Photoplethysmography - The analysis of the transmission of light through the skin and underlying blood vessels has long been indispensable in medicine, for example in pulse oximeters. Its digital cousin, so-called remote photoplethysmography (rPPP), is an emerging method in telehealthcare, which uses webcams to estimate vital signs. But rPPP can, in theory, also be used in deepfake detectors.

In recent years, such experimental rPPP-based deepfake detectors have proven good at distinguishing between real and deepfaked videos. These successes led some experts to judge that current deepfakes couldn't yet mimic a realistic heart rate. But now, it appears that this complacent view is outdated.

"Our experiments have shown that current deepfakes may show a realistic heartbeat, but do not show physiologically realistic variations in blood flow across space and time within the face."

One of a kind: Humans have unique breathing 'fingerprints' that may signal health status
Jun 2025, phys.org

Scientists can identify individuals based solely on their breathing patterns with 96.8% accuracy. 

This high-level accuracy remained consistent across multiple retests conducted over a two-year period, rivaling the precision of some voice recognition technologies. Respiratory fingerprints correlated with a person's body mass index, sleep-wake cycle, levels of depression and anxiety, and even behavioral traits. For example, participants who scored relatively higher on anxiety questionnaires had shorter inhales and more variability in the pauses between breaths during sleep.

'Solastalgia' might help explain effects of climate change on mental health
Aug 2025, phys.org

Solastalgia - blend of the words "solace" and "nostalgia"; first coined in 2003 to refer to the lack of solace and feelings of pain or sickness caused by changes in a person's immediate or surrounding environment, and now found to be associated with depression, anxiety, and posttraumatic stress disorder. (Out of an initial 80 studies between 2003 and 2024, 5 quantitative and 14 qualitative studies from Australia, Germany, Peru and the U.S., totaling 5,000+ participants were considered.) Also considered one of several eco-emotions, such as eco-anxiety, eco-grief, or eco-shame, or eco-guilt

Searching for Artificial Memory Systems in ancient humans with spatial statistics
Aug 2025, phys.org

Paleolithic Artificial Memory System - like tally marks on bone - devices that record, store, transmit, and retrieve coded information beyond the brain, via external representations. AMS can be anything from the notches on a gunslinger's pistol, tracking past success, to the symbols on and data encoded within the Voyager spacecraft's golden record ... Documented functions include a North American lunar-cycle calendar, Australian message sticks, medieval English tally sticks for expenditures and taxes, a Tibetan tally stick for wheat and millet deliveries, and Angolan tally sticks for days traveled.

Thanks Craigslist


In a fit of irony, I had never heard of this, and nobody I told this to had ever heard it either. This article is about polarization, but it's also about the decline of the news industry, the same industry that didn't do such a good job spreading this particular story over the past several years.


How the rise of Craigslist helped fuel America's political polarization
Aug 2025, phys.org

Craigslist launched in San Francisco in 1995, and over time effectively killed off the humble newspaper classified ad, which in the year 2000, made 30% of their revenues.

Craigslist rolled out in an idiosyncratic city-by-city expansion. This staggered spread created what is known in economics as a natural experiment.

This needs some explanation, so I'm copying most of it:

Looking at more than 1,500 newspapers, the researchers could compare what happened before and after Craigslist arrived, isolating its effects from other factors like the rapid expansion of broadband internet.

Newspaper executives axed a lot of the expensive, "prestige" political coverage that classifieds had subsidized, because it wasn't something readers flocked to, and it cost more to produce than sports or entertainment.

Following the entry of Craigslist in a market, newspapers reduced mentions of politicians competing in local congressional races by an average of 12%. The missing coverage also led to declines in circulation, particularly among readers interested in general news, who tended to be more educated, wealthier, and more politically engaged.

"When they're less informed and they're less likely to get solid information, they tend to go to extremes, because they don't have the information that the extreme candidates are extreme."

Readers who didn't follow politics closely were also affected. "You may not have been reading the newspaper because you wanted to learn about politics, but the stories about politics were bundled together with the things that you did care about."

When local political coverage disappeared, along with it went an important way for many voters to spot the differences between candidates, particularly unknown candidates running in party primaries. In a world of perfect information, extreme candidates would usually lose, because their stances are by definition far from the average voter's. When voters have less information available to ferret out political positions that do not align with their views, they cast more votes for extreme candidates.

"The reduction in staff covering politics made it harder for voters to differentiate between moderates and extremists in partisan primaries, and allowed extreme candidates to do better than they did before." This, in turn, fueled political polarization.

[And I guess this is why the City University of New York announced in 2024 a $10 million gift from Craig Newmark for a tuition-free Graduate School of Journalism.]

Post Script
I'll record here only for personal posterity's sake, a line of reasoning that follows from this - does this mean that advertising (in the form of classifieds) is necessary for democracy? I know Ben Franklin's newspaper in Philadelphia was funded by advertisers. Is it supposed to be government-funded? Sounds like someone needs to take a political science course. 

Post Post Script
This makes the social media problem circa the 2020's even more sinister, since these platforms, some of which are also the largest companies in the world, they're not only taking the advertising dollars from traditional media, but they're also incentivizing the opposite of information (in the form of dis- and mis-information). I mean they don't even employ journalists, nevermind the fact that they propagate on their networks non-news (as in, fake news from fake news outlets created with names to sound similar to reputable news outlets).
