Optomania


I'm starting to get bedazzled by the light hype, it's like there's nothing you can't say at this point that might not be actually true. Disembodied decentralized swarm neurons? Yes. Artificial evolution engine running on hijacked bacterial botnets? Sure. Non-electronics-based large-scale programmable incoherent photonic neuromorphic computing system? That is exactly what was going to happen all along. The somatic override helmet that shoots lasers into your bloodstream is a bit over the top however. 


When light 'thinks' like the brain: The connection between photons and artificial memory
Feb 2026, phys.org

(It was a surprise they said.) Italian researchers show that identical photons propagating within optical circuits spontaneously behave like a Hopfield Network, one of the best-known mathematical models used to describe the associative memory mechanisms of the human brain.

"In this system, photons are not merely carriers of data, but themselves become the 'neurons' of an associative memory."

Light-guided 'optovolution' evolves proteins that switch states on schedule
Mar 2026, phys.org

Optovolution - uses light to guide the evolution of proteins with dynamic, multi‑state, and computational functions - making yes-or-no decisions based on specific rules

The team built their system in the budding yeast Saccharomyces cerevisiae, widely used to brew beer and a laboratory workhorse. They rewired the yeast's cell cycle so that progression depended on the protein to be evolved, switching cleanly between off and on states.

The key was linking the protein's output signal to a cell‑cycle regulator that is essential at one stage but toxic at another. If the protein of interest stayed on or off for too long, the yeast cell stalled or died. Only cells in which the protein oscillated correctly could keep dividing.

Photonic chips advance real-time learning in spiking neural systems
Mar 2026, phys.org

"Photonic spiking neural systems use brief optical pulses, or spikes, to emulate neural signaling, but they can typically only process the linear parts of computation using light. Previously, the nonlinear steps that make learning and decision-making possible required the signal to be converted back into electronic signals. This adds delay and undercuts the speed and energy advantages of photonics."

Ultrasound creates light inside the body, opening a new path to targeted treatments
Apr 2026, phys.org

I believe they are shooting lasers through the fluids in your blood vessels - I'll be on my way now.

Nanomaterials distributed through the bloodstream to turn ultrasound waves into precise points of light - "With these materials, we can produce light emission in the brain, in the gut, in the spinal cord, in the muscle—virtually anywhere—without needing a physical implant."

They started with large, ceramic particles that give off light in response to mechanical stress, which can be created by ultrasound waves. Then they created a biocompatible coating for the particles and injected them into mice.

The researchers created a small ultrasound-producing hat for mice, and used it to create light that stimulated different neurons, causing the mouse to turn left or right depending on the part of the brain being activated.

Distinguishing 'things' from 'stuff': Brain's visual processing areas separate solid objects from flowing substances
Jul 2025, phys.org

Things - rigid or deformable objects like a bouncing ball
Stuff - liquids or granular substances such as sand

"When you're looking at some fluid or gooey stuff, you engage with it in different way than you do with a rigid object. With a rigid object, you might pick it up or grasp it, whereas with fluid or gooey stuff, you probably are going to have to use a tool to deal with it"

Language structure shapes color-adjective links even for people born blind, study reveals
Apr 2025, phys.org

"Certain colors are strongly associated with certain adjectives (e.g., red is hot, blue is cold)" 

"Some of these associations are grounded in visual experiences such as seeing glowing red embers. Surprisingly, despite having no visual experience, many congenitally blind people show very similar color associations, which are likely learned through language. We show that these associations are indeed embedded in the statistical structure of language."

A universal rhythm guides how we speak: Global analysis reveals 1.6-second 'intonation units'
Aug 2025, phys.org

Human speech across the world pulses to the beat of what are called intonation units, short prosodic phrases that occur at a consistent rate of one every 1.6 seconds.

Intonation units play a critical role in helping listeners follow conversations, take turns speaking, and absorb information. 

The research analyzed over 650 recordings in 48 languages spanning every continent and 27 language families.

What's in a name? Information structure parallels discovered across cultures—with repercussions for Asian names
Feb 2026, phys.org

(ie, Name Entropy)

Fixing of Western last names around the 1600's meant a loss of information within the naming system, which had to be compensated for - which is why first names now convey more and more information (there's more first names than there used to be).

Naming systems must allow for the separate identification of a large number of people, while keeping the total number of words required by the system manageable so that they don't overtax people's brains as they process them.

In England, in every 50-year period between 1550 and 1880, half of the male population was given the first names John, William, or Thomas, and half the female population Ann, Mary, or Elizabeth.

Today, in Korea, it's the opposite, in both ways, because half the population still has 6 names, and in Asia, they come first, not last - Kim Jong Il would be called Jong Il Kim in the West. And I can't find it in the paper but I think the 6 names would be something like Kim, Park, Lee, Son, ...

From the paper itself, using badminton player Simon Archer and the basketball player Yao Ming 姚明 - Simon and Yao are names, whereas Archer is an English word for someone who shoots arrows with a bow, and Ming is a Chinese word meaning brightness.

The problem is that, because of the focus on inherited names in the Western system, the order of names of researchers from East Asian countries is reversed for publication. For Asian researchers, this means that the part of the name that conveys more information is initialized, and the part that conveys less is written out in full.

"For researchers from China today, it is as if Charles Darwin, Charles Dickens, and Charles Dodgson had all been forced to publish their works under the name Charles D."

Study suggests people are losing 338 spoken words every year and have been for at least 15 years
Apr 2026, phys.org

(Surprise) We were replicating an earlier paper on gender differences in how many words men and women speak per day. My collaborator, Valeria Pfeifer, came to me with the word counts from the replication analyses using the same methodology as our 2007 paper, but with 2,200 new participants across 22 studies. Our estimate of daily spoken word average came in at around 12,700 words. Our 2007 estimate had been 15,900. I told her there had to be a mistake. But she rechecked everything, and the number held. Something had genuinely changed.

These studies were conducted for entirely different purposes—coping with breast cancer, adjustment after divorce, the social effects of meditation, relationship dynamics. None of them were designed to track how much people talk over time. Participants had no idea their word counts would ever be analyzed this way, which rules out any concern that people adjusted their behavior to fit a hypothesis.

Young adults under 25 showed a steeper decline, about 452 words per year, compared to 314 for older adults.

Small talk shapes big trends: Physics predicts how language patterns spread
May 2026, phys.org

The model is a step towards understanding the "statistical physics of language" - Professor Burridge tested his approach against large-scale survey data on American dialects collected by the Cambridge Online Survey of World Englishes, created by Bert Vaux, a professor of linguistics at the University of Cambridge. 

In 1950, the term roly-poly for a woodlouse was largely confined to a relatively small group of speakers in the American South. By 1995, the term had spread dramatically, becoming almost universal across much of the United States.

"Splinter is used across almost all of England, except around Newcastle, where people still say spelk. Although Newcastle itself is densely populated, it is surrounded by more sparsely populated areas, which helps the local form hold its ground and prevents splinters from taking over.

Unexpected Intent


Superheated gold withstands 'entropy catastrophe': New method challenges established physics
Jul 2025, phys.org

In an experimental debut, the team superheated solid gold far beyond the theoretical limit, unexpectedly overturning four decades of established theory. The team was thrilled to have successfully demonstrated this technique—and as they took a deeper look at the data, they discovered something even more exciting.

"We were surprised to find a much higher temperature in these superheated solids than we initially expected, which disproves a long-standing theory from the 1980s," White said. "This wasn't our original goal, but that's what science is about—discovering new things you didn't know existed."

In their recent study, the team discovered that the gold had been superheated to an astonishing 19,000 kelvins (33,740 degrees Fahrenheit) - more than 14 times its melting point and well beyond the proposed entropy catastrophe limit - all while maintaining its solid crystalline structure.

"It's important to clarify that we did not violate the Second Law of Thermodynamics," White said with a chuckle. "What we demonstrated is that these catastrophes can be avoided if materials are heated extremely quickly — in our case, within trillionths of a second."

The researchers believe that the rapid heating prevented the gold from expanding, enabling it to retain its solid state. The findings suggest that there may not be an upper limit for superheated materials, if heated quickly enough.

How a one‑eyed creature gave rise to our modern eyes
Feb 2026, phys.org

"The results are a surprise. They turn our understanding of the evolution of the eye and the brain upside down"

All vertebrates evolved from a distant ancestor that had a single eye located at the top of its head, and the remnants of this so-called median eye have today become the pineal gland in our brains.

600 million years ago, a worm that had two eyes, for some reason, lost them, but kept a group of light-sensitive cells in the middle of its head that developed into a small, primitive median eye that could keep track of night and day, and sense what was up and down.

A million years later, from parts of the small median eye, new image-forming eyes in pairs developed. 

"Now we finally understand why the eyes of vertebrates differ so radically from the eyes of all other animal groups, such as insects and squid. The film of our eyes—the retina—developed from the brain, whereas the eyes of insects and squid originate in the skin on the sides of the head."

A fascinating fact is that remnants of the ancient parietal median eye from our distant ancestor actually remain in our heads today, transformed into the pineal gland. The pineal gland is a light-sensitive organ in the vertebrate brain. It produces the hormone melatonin, which helps regulate the body's circadian rhythm.

"It's mind-boggling that our pineal gland's ability to regulate our sleep according to light stems from the cyclopean median eye of a distant ancestor 600 million years ago,"

Believe It or Not Everything Is Made of Plastic


This title is supposed to be a joke, and a pun, because artificial spacetime is obviously "plastic", in the original sense of the word. But really, just about anything called "natural" is actually made of petrochemicals and other industrial by-products, because people who buy words instead of things can't tell the difference! 
 
Microrobots overcome navigational limitations with the help of 'artificial spacetimes'
Nov 2025, phys.org

Researchers found that the robots' motion is formally identical to the path light takes in general relativity, which allowed them to develop a mathematical framework mapping robot motion to geodesics in a curved spacetime defined by a control field — as in other reactive control methods. The team used conformal transformations to map complex environments to simple virtual spaces, then designed control fields and mapped them back. They refer to the resulting geometric framework as "artificial spacetimes."

Bamboo dishes may leach pesticides and melamine into food
Nov 2025, phys.org

"The 'natural' label can be dangerously misleading. Many of these products are essentially plastic dishes made from melamine-formaldehyde resin containing bamboo filler. Our research shows this combination can accelerate the polymer's degradation and increase the migration of harmful substances like melamine, especially into hot or acidic foods and drinks."

  • Melamine was present in 32% of the tested products; 33 bio-based dishes including bowls, cups, and dining sets purchased from markets in the Czech Republic, the United Kingdom, and China. 
  • Six of the bamboo-based products released melamine above the European Union specific migration limit (SML) of 2.5 mg/kg. 
  • Melamine leached into common beverages, including hot lemon tea and orange juice, highlighting a direct route of consumer exposure.
  • Several bio-based dishes, particularly those made from cereals, contained residues of pesticides.
  • Disinfectants were the primary residues found in the bamboo-based items.

Although the use of bamboo as an additive in plastic food contact materials has been banned in the EU since 2021 due to these risks, the study confirms that these items are still available for purchase. The research highlights the false advertising common with these products, which are often labeled as "100% bamboo" or "biodegradable" despite being composed of a plastic resin.

Why strange cures made sense in mysterious times
Dec 2025, phys.org

"We wanted to know whether the logic of folk medicine followed psychological patterns and it does. The more uncertain or mysterious the illness, the more likely the cure involved magic or religion."

Researchers from Brunel University of London have mined a rare archive of 3,655 folk cures, collected in the 1930s, from an extraordinary national folklore project launched in Ireland. About 50,000 schoolchildren were asked to interview parents, grandparents and neighbors about local history, beliefs and cures. Teachers then transcribed the accounts, creating one of the most detailed records of oral folk medicine ever compiled. They were recently digitized. 

To make sense of the archive, researchers focused on 35 diseases and asked two doctors to rate each one according to how understandable it would have seemed to a layperson at the time, both in terms of what caused the illness and what was going on in the body. Obvious cases like cuts and sprains were marked as "certain"; conditions like tuberculosis, warts, or epilepsy were labeled more mysterious.

"It's pretty unsatisfying just not having a solution of any form. When there aren't particularly good medical solutions, I expect people will keep searching for something that makes sense."

Hegemonic Power, Synthetic Humans, and the SAG-AFTRA-AI Manifesto


It might be considered the first real big fight between humans and robots. To summarize into a very, very simple, and incomplete explanation, it happens at a time when the labor union of people who work on movies have to re-negotiate their contract with the people who pay them. They went on strike for 118 days, the longest actors’ strike in Hollywood history. Now they have a new contract.

The problem was that if there's one thing artificial intelligence can do, it's art (as opposed to law, medicine, engineering, etc.). Not saying it's necessarily good at art, but it's sure as hell good enough for the people who pay for movies to be made, and who then go on to make money off those movies. Not sure if it's good enough for the people who pay to watch these movies, but then again, it doesn't seem like anyone needs to care about consumers anymore anyway, so...the people who work on movies are in for a fight if they want to be treated like humans. 

The problem, for the rest of us, is that we're humans too. Well, not if you're reading this, because the only people who read this weblog are in fact robots. But the rest of us are humans. And for the first time since Africa, we are facing real competition.

Below is a report about the 2023 SAG-AFTRA labor story, and some good bits about how humans and robots are being positioned against each other in the labor market, and what that might mean for us in the future. It's written by Data and Society Institute (citation at the very bottom, and in-text references you'll just have to get for yourself from the document; because sorry sir this is a Wendy's).

On Common Sense, Machine Learning and Big Data
Common sense, or a skewed perception of reality that perpetuates the status quo as normal, natural and unquestionable, is an expression of hegemonic power. The concept of common sense describes commonly held — yet nonetheless fragmented and heterogenous - knowledge that often goes unquestioned as fact (Gramsci,1926/1971). 
 
According to critical theorist Hito Steyerl's (2023) power analysis of machine learning technologies, the power of the owning class depends on its seizure of data. Thus, the discussion of for-profit technology, and speci!cally various applications that track, record, and classify user data, can never be liberatory, despite the claims of the companies, industries, and institutions promising safety, accessibility, efficiency, and sustainability (Bender and Hanna, 2025; Benjamin, 2019).

The “common sense” of AI, that is, the widely-held belief that AI is a foregone conclusion, functions as an articulation of hegemonic power. In this frame, we seek to understand how the labor movement can meaningfully intervene.

AI is not simply a discursive formation that stands as a “common sense” foregone conclusion, it also obfuscates large-scale, transnational coordination of resources, labor, and people who make up the infrastructures that are required for arti!cial intelligence. This matters because it broadens the base for possible coalition building to be mobilized in these “processes of subtraction” (Steyerl, 2023, p. 12).

Data and Society, 2026


See Figure 1 - The four strategies on the left negotiate with the common sense of AI, giving it power and weight, as these strategies work with AI as it is, instead of disengaging with the common sense of AI, and pushing these technologies to work that are commons-based or people-centered.

Robots in Human Clothing, ie The Corporate Flesh Engine
Amazon has long referred to their Mechanical Turk platform as artificial intelligence, but there have always been humans doing the often-underpaid work of classifying and sorting content of all types, increasingly in the Global South (Crawford, 2021; Gonzalez-Cabello et al., 2025). This hidden labor has been referred to as “ghost work” (Gray and Suri, 2019; Muldoon et al., 2024) and “human-fueled automation” (Irani, 2019), drawing attention to the people who power AI systems. 

Synthetic Performers (i.e., entirely digitally-produced performers created through generative AI). The [new negotiated contract] establishes guidelines around the creation and use of “digital replicas” and “synthetic performers.”

Digital replicas are digital reproductions of an actor's voice or likeness. The contract described two types of digital replicas: “employment-based digital replicas” and “independently created digital replicas.”

Employment-based digital replicas are those that are created during the actors’ physical participation in work through methods such as scanning, which can then be used to depict the actor in scenes they did not actually perform.

Independently created digital replicas are made without the actor's physical participation and can perform in scenes that they did not perform. The parameters of consent and compensation vary depending on the type of technology utilized. The guidelines for synthetic performers created through generative AI are less robust than those for digital replicas. Synthetic performers are entirely digitally-produced performers created through generative AI that do not resemble a recognizable actor and are not voiced by a person. The contract requires that studios who want to use a synthetic performer must notify and provide the union with opportunities to bargain over the usage of a synthetic performer in lieu of hiring a human performer. A document drafted by the union with frequently asked questions on AI notes that “for wholly synthetic assets, [studios] cannot use them without notifying the union and bargaining. Had we not done that, there was nothing stopping them from using these synthetic assets without anyone's consent.”

The contract also notes that if studios create a synthetic performer through prompting a generative AI system using a performer's name and their “principal facial feature” — the mouth, nose, eyes, or ears — that is recognizable, studios must bargain with the performer and obtain their consent.

However, for synthetic performers and independently created digital replicas, there are exceptions for consent with regards to uses protected by the First Amendment. A summary of the tentative agreement lists these exceptions as “comment, criticism, scholarship, satire or parody, use in a docudrama, or historical or biographical work.” In the aforementioned types of projects, studios do not need to obtain consent from performers to use their digital doubles.

Psychosis Engine


There are some conflicting findings floating around the electroniverse. Japanese philosophizing psychologists suggests that addicts make phones look bad, and a Netherlands twin study says something similar. Likely only a coincidence that these studies were coming out at the same time Facebook was on trial in California for intentionally hurting kids. 

In the end, the only conclusion we can make is that science is hard:

People who are easily distracted by smartphones are more physiologically reactive, less attuned to their bodies
Apr 2025, phys.org

People who have an attentional bias towards smartphone stimuli typically display a lower interoceptive awareness, meaning they were less attuned to internal bodily signals such as their heartbeat - a pattern mirroring behavioral addictions like gambling or substance use.

Note, Japanese institutions think differently about the intersection of humans and technology:
"This project began as an interdisciplinary exploration between philosophy and psychology, aiming to understand the relationship between technology and the human body."

Twin study challenges oversimplified claims about social media and well-being
Oct 2025, phys.org

6,000 twins in the Netherlands:
  • Small associations were found between social media use and well-being, with most being either negligible or statistically minor.
  • Genetic influences explained up to 72% of the variation in how much time people spend on social media.
  • People with higher well-being tended to use more platforms, but more passively (browsing rather than posting).
  • Those with lower well-being were more likely to post frequently on fewer platforms.

Social media research tool can lower political temperature — it could also lead to more user control over algorithms
Nov 2025, phys.org

Key: This research was done "without the direct cooperation of the platform"

Web extension tool coupled with an artificial intelligence large language model that scans posts for antidemocratic and extreme negative partisan sentiments. The tool then re-orders posts on the user's X feed in a matter of seconds:

Antidemocratic attitudes:
  • advocating for extreme measures against the opposing party
  • statements that show rejection of any bipartisan cooperation
  • skepticism of facts that favor the other party's views
  • willingness to forgo democratic principles to help the favored party

Where has this been all these years? Consider, there is often an immediate, unavoidable emotional response to seeing ^this kind of content ... making people feel bad the moment they see it.

New Things in Color Tech

 

We have cracked the color-changing codes of both the chameleon and the octopus, we're printing structural color from an inkjet, and making something apparently darker than vantablack. But I'm really just here to say words like nanophotonic metamaterials, and quantum polycrystals. 

'OCTOID,' a soft robot that changes color and moves like an octopus
Dec 2025, phys.org

By precisely controlling the helical molecular arrangement and polymer network structure of this material, they achieved a structure capable of both soft, flexible movement and color changes, just like an actual octopus tentacle.

When an electrical signal is applied, the helical molecular arrangement and polymer network structure of this material's surface undergoes microscopic contraction and expansion, displaying a continuous color change from blue to green to red. It also performs bending and unfolding motions through asymmetric structural changes. Through this process, OCTOID can simultaneously perform three functions - camouflaging, moving, and grabbing - within a single system, just like a real octopus.

Chameleon-like nanomaterial can adapt its color to mechanical strain
Dec 2025, phys.org

2D nanophotonic metamaterial - Kirigami-inspired structural color, as different from pigment or dye colors - When the material is stretched, its microscopic patterns move and rotate, changing how light reflects from the surface. As a result, during the stretching, the color of the light reflected from this 'nanoscale chameleon skin' shifts smoothly from green to yellow and finally to red.

Smart material instantly changes colors on demand for use in textiles and consumer products
Dec 202,5 phys.org

They stacked a thin layer of vanadium dioxide on top of a reflective aluminum layer. When heated above a specific temperature, the vanadium dioxide turns from an insulator to a metal, accompanied by a change in its crystalline structure. When light hits this stack, some bounces off the top of the vanadium dioxide, while the rest passes through and bounces off the aluminum below. These two reflected paths of light interfere with each other. The rapid structural change in vanadium dioxide alters the timing of light bouncing from the top and the bottom, making them out of phase. This changes the color that is canceled out, which, in turn, changes the color we see.

Structural color can now be printed with an inkjet printer
Apr 2026, phys.org

Spherical silicon crystals that reflect color specifically based on their precise size in the range between 100 and 200 nanometers can now be printed at resolutions between 250 and 125 dots per inch onto a flat PET film as well as on a 3D metallic surface.
