Round 2 - Mollusca - Bivalvia

(Sources - 1, 2, 3, 4)

Bivalvia is a class of molluscs whose bodies are enclosed by a pair of half-shells called valves, though some bivalves, like the Naked Clam (Chlamydoconcha orcutti) (image 2) have secondarily lost their shells. Bivalves have no head and no radula. Their gills have evolved into ctenidia, specialised organs for feeding and breathing. Bivalvia includes the clades Heteroconchia, Palaeoheterodonta, Protobranchia, Pteriomorphia, and animals commonly known as clams, oysters, cockles, mussels, and scallops.

Bivalves live in marine and freshwater environments. Most are filter feeders that bury themselves in sediment, lie on their side on the seafloor, or attach themselves to rocks or other hard surfaces. Some bivalves, such as scallops and file shells, can swim (see gif below). Shipworms bore into wood, clay, or stone and live inside these substances. Bivalve shells are composed of two calcareous valves joined along one edge by a flexible ligament that, usually in conjunction with interlocking "teeth" on each of the valves, forms the hinge, allowing the animal to open and close its shell. The animal secrets its shell from lobes on its mantle. They have a foot located at the front of their shell and two siphons in the back, which inhale and expell water. The shipworms, of the family Teredinidae, have elongated bodies but tiny, reduced shell valves, which function as scraping organs that permit the animal to dig tunnels through wood. Bivalves have sensory organs located on the margins of their mantle, usually mechanoreceptors or chemoreceptors, sometimes on short tentacles. All bivalves have light-sensitive cells that can detect a shadow falling over the animal, some have simple eyes on the margin of the mantle, and scallops have complex eyes with a lens, a two-layered retina, and a concave mirror. Most bivalves are filter feeders, using their gills to capture particles of food such as phytoplankton from the water. Protobranchs feed in a different way, scraping detritus from the seabed with mucus-covered tentacles. A few bivalves, such as the Granular Poromya (Poromya granulata), are carnivorous, eating larger prey like small crustaceans, though they will also scavenge. It does this though its inhalant siphon which is modified into a cowl-shaped organ, sucking in prey, and then inverting to bring the prey within reach of the mouth.

Most bivalves have separate sexes, though some are hermaphroditic. Fertilization is external in most species. Spawning may take place continually or be triggered by environmental factors such as day length, water temperature, or the presence of sperm in the water. Eggs hatch into free-swimming, planktonic trochophore larvae. These later develop into veliger larvae which settle on the seabed and undergo metamorphosis into adults. In some species, such as those in the genus Lasaea, females draw sperm in through their inhalant siphons and fertilize their eggs inside their bodies. These species then brood the young inside their mantle cavity, eventually releasing them into the water column as veliger or glochidia larvae or as crawl-away juveniles. The juveniles of freshwater bivalves will attach themselves parasitically to the gills or fins of a fish host. After several weeks they drop off their host, undergo metamorphosis and develop into adults on the substrate.

Bivalves first appear in the fossil record in the Early Cambrian. Possible early bivalves include Pojetaia and Fordilla, though these are probably stem-bivalves. True Cambrian bivalves may include Camya, Arhouriella, and Buluniella. Bivalves began to diversify during the Early Ordovician. By the Early Silurian, gills were adapting for filter-feeding, and during the Devonian and Carboniferous periods, siphons first appeared along with the newly developed muscular foot. At this point Brachiopods were still the most dominant filter-feeders in the ocean, but the Permian–Triassic extinction event hit both brachiopods and bivalves hard, but resulted in bivalves becoming the more common filter-feeders by the Triassic Period.

Propaganda under the cut:

Bivalves have long been a part of the diet of coastal and riparian human populations. Oysters were cultured in ponds by the Romans, and mariculture has more recently become an important source of bivalves for food.

Pearl Oysters (the common name of two very different saltwater and freshwater families) are the most common source of natural pearls.

Some of the species in the freshwater mussel family Unionidae (commonly known as Pocketbook Mussels) have evolved an unusual reproductive strategy. The female's mantle protrudes from the shell and develops into an imitation small fish, complete with fish-like markings and false eyes. This decoy moves in the current and attracts the attention of real fish. When fish approach for a closer look the mussel releases huge numbers of larvae from its gills, dousing the inquisitive fish with its tiny, parasitic young. These glochidia larvae are drawn into the fish's gills, where they attach and trigger a tissue response that forms a small cyst around each larva. The larvae feed on the tissue of the fish within the cysts. After a few weeks they release themselves from the cysts and fall to the stream bed as juvenile molluscs.

One genus, Entovalva, are parasitic as adults, being found only in the esophagus of sea cucumbers. They attach themselves via byssal threads to the host's throat, filter-feeding from the sediment sucked in by the sea cucumber. (This does not hurt the sea cucumber.)

The largest bivalve is the Giant Clam (Tridacna gigas) which can weigh over 200 kilograms (440 lb), measure as much as 120 cm (3.11 ft) across, and have an average lifespan in the wild of more than 100 years.

The shells of bivalves are used in craftwork, and the manufacture of jewellery and buttons.

As filter-feeders, bivalves are natural water filters. A single 5.08 cm (2 inch) clam can filter up to 10-12 gallons of seawater a day. They can even filter microplastics out of polluted water.

When they live in polluted waters, bivalves have a tendency to accumulate substances such as heavy metals and persistent organic pollutants in their tissues. This is because they ingest the chemicals as they feed but their enzyme systems are not capable of metabolising them and as a result, the levels build up. This may be a health hazard for the molluscs themselves, and is one for humans who eat them. It also has advantages in that bivalves can be used in monitoring the presence and quantity of pollutants in their environment.

The farming of bivalves is more ecologically-friendly than the farming of chordates as, rather than create waste, bivalves like mussels and oysters actually clean the water.

Scottish and Irish rocks confirmed as rare record of ‘snowball Earth’

A rock formation spanning Ireland and Scotland may be the world’s most complete record of “snowball Earth”, a crucial moment in planetary history when the globe was covered in ice, finds a new study led by UCL (University College London) researchers.

The study, published in the Journal of the Geological Society of London, found that the Port Askaig Formation, composed of layers of rock up to 1.1km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation – the first of two global freezes thought to have triggered the development of complex, multicellular life.

One exposed outcrop of the formation, found on Scottish islands called the Garvellachs, is unique as it shows the transition into “snowball Earth” from a previously warm, tropical environment.

Other rocks that formed at a similar time, for instance in North America and Namibia, are missing this transition.

Senior author Professor Graham Shields, of UCL Earth Sciences, said: “These rocks record a time when Earth was covered in ice. All complex, multicellular life, such as animals, arose out of this deep freeze, with the first evidence in the fossil record appearing shortly after the planet thawed.”

First author Elias Rugen, a PhD candidate at UCL Earth Sciences, said: “Our study provides the first conclusive age constraints for these Scottish and Irish rocks, confirming their global significance.

“The layers of rock exposed on the Garvellachs are globally unique. Underneath the rocks laid down during the unimaginable cold of the Sturtian glaciation are 70 metres of older carbonate rocks formed in tropical waters. These layers record a tropical marine environment with flourishing cyanobacterial life that gradually became cooler, marking the end of a billion years or so of a temperate climate on Earth.

“Most areas of the world are missing this remarkable transition because the ancient glaciers scraped and eroded away the rocks underneath, but in Scotland by some miracle the transition can be seen.”

The Sturtian glaciation lasted approximately 60 million years and was one of two big freezes that occurred during the Cryogenian Period (between 635 and 720 million years ago). For billions of years prior to this period, life consisted only of single-celled organisms and algae.

After this period, complex life emerged rapidly, in geologic terms, with most animals today similar in fundamental ways to the types of life forms that evolved more than 500 million years ago.

One theory is that the hostile nature of the extreme cold may have prompted the emergence of altruism, with single-celled organisms learning to co-operate with each other, forming multicellular life.

The advance and retreat of the ice across the planet was thought to have happened relatively quickly, over thousands of years, because of the albedo effect – that is, the more ice there is, the more sunlight is reflected back into space, and vice versa.

Professor Shields explained: “The retreat of the ice would have been catastrophic. Life had been used to tens of millions of years of deep freeze. As soon as the world warmed up, all of life would have had to compete in an arms race to adapt. Whatever survived were the ancestors of all animals.”

For the new study, the research team collected samples of sandstone from the 1.1km-thick Port Askaig Formation as well as from the older, 70-metre thick Garbh Eileach Formation underneath.

They analysed tiny, extremely durable minerals in the rock called zircons. These can be precisely dated as they contain the radioactive element uranium, which converts (decays) to lead at a steady rate. The zircons together with other geochemical evidence suggest the rocks were deposited between 662 and 720 million years ago.

The researchers said the new age constraints for the rocks may provide the evidence needed for the site to be declared as a marker for the start of the Cryogenian Period.

This marker, known as a Global Boundary Stratotype Section and Point (GSSP), is sometimes referred to as a golden spike, as a gold spike is driven into the rock to mark the boundary.

GSSPs attract visitors from around the world and in some cases museums have been established at the sites.

A group from the International Commission on Stratigraphy, a part of the International Union of Geological Sciences, visited the Garvellachs in July to assess the case for a golden spike on the archipelago. Currently, the islands are only accessible by chartering a boat or by sailing or kayaking to them.

In reference to this post as promised I'm elaborating

Alive is defined by the Oxford Dictionary as;

(of a person, animal, or plant) living, not dead Alert and Active; animated

Merriam-webster defines Alive as;

Having life: not dead or inanimate

Both of these fit what we see with characters such as Boothill, but in biological science, there is more complexity regarding what is or can be defined as alive.

Throughout my science degree, I must consistently refer to the expanded definition. Because of that, I have struggled to define certain organisms in a strictly 'alive' or 'dead' definition. The definition of life is complex and multifaceted and is typically defined by 7 key characteristics, these are

Cellular Organization: All living organisms are composed of one or more cells, which are considered the basic units of life.

Metabolism: Living organisms undergo chemical reactions that allow them to transform energy and materials from their environment into usable forms. This includes processes such as respiration, digestion, and photosynthesis.

Growth and Development: Living organisms grow and develop according to specific instructions coded for by their DNA or RNA.

Reproduction: Living organisms have the ability to reproduce, either sexually or asexually, to produce new individuals of the same species.

Response to Stimuli: Living organisms can respond to environmental stimuli, such as light, temperature, and touch.

Homeostasis: Living organisms maintain a stable internal environment, regulating factors such as temperature, pH, and hydration to sustain life.

Adaptation and Evolution: Living organisms have the ability to adapt to their environment through the process of evolution by natural selection over generations.

These criteria form the basis of our understanding of life. However, some entities like viruses challenge these criteria, as they exhibit some but not all characteristics of life, such as having genetic material and evolving, but lacking cellular structure and metabolism on their own.

Now back on topic, Boothill is in a way pseudo-dead/alive. Shrodiger's cowboy if you will. He exists in the grey area between the definition of living and non-living. Now if we work through the list above and work out the rough percentage of the scientific definition our favourite galaxy ranger fits into. I'll start from the top, as far as we are aware (please correct me if I'm wrong) Boothill is lacking a majority of his original cellular makeup, excluding what's left visible of his skin which I assume isn't synthetic. Assuming all of this he fits the first characteristic poorly and therefore I'm giving him an F+ for effort. The second characteristic is metabolism... I'm going to just instantly fail him because I don't think bullets truly have any nutritional value and therefore he gains no energy from them (I also highly doubt he needs more than a phone charger cable to stop himself from powering down with the Windows shutdown noise). Growth and Development, unless he's made of a biological metal that can grow he also fails in this department, he also lacks a majority of his original biological makeup which also means he fails.

(Boothill isn't doing so well so far...)

Reproduction... I think this one is pretty self-explanatory. I highly doubt there was any need for there to be any reproductive organ and therefore he has no way to reproduce. (Sorry to all the fanfic authors out there that have just had a field day coming up with as many different ways this man can get some, keep being as delusional as you wish I won't judge). Finally, we reach one Boothill can do (YAY!!!) response to stimuli. despite him not having any or very little feeling in his mechanical body parts there is still his face and very pinchable cheeks. I'm also going to treat his lack of feeling as being similar to people with severe nerve damage, still alive and just can't feel shit. Now, fanfics also enjoy this one, homeostasis, it makes sense that he would be able to regulate internal temperature especially because overheating would fry him like a chip in oil. So I'm fully on board with this man being able to sound like my laptop when I use it for too long or open a million different AO3 tabs. (plus a flustered Boothill sounding like an overheating laptop is a hilarious thought to me). the last characteristic is adaption and evolution, this to me links to reproduction as it typically refers to the entire 'species' not just an individual. another fail.

Out of the seven characteristics Boothill fits at best two. This means he's at best 28.5% alive, not a good mark if it were a test but interesting. As far as I'm concerned he's similar to a virus in the sense that despite not fitting into the characteristics that well he's still very much alive.

Apologies for the long read, I had a brainworm and needed to free it.

The Entangled Brain 🧠

The Brain Is Much Less Like A Machine Than It Is Like The Murmurations of A Flock of Starlings Or An Orchestral Symphony

— Luiz Pessoa | Edited By Sam Dresser | 19 May 2025

Photo By Sarah Mason/Getty Images

When thousands of starlings swoop and swirl in the evening sky, creating patterns called murmurations, no single bird is choreographing this aerial ballet. Each bird follows simple rules of interaction with its closest neighbours, yet out of these local interactions emerges a complex, coordinated dance that can respond swiftly to predators and environmental changes. This same principle of emergence – where sophisticated behaviours arise not from central control but from the interactions themselves – appears across nature and human society.

Consider how market prices emerge from countless individual trading decisions, none of which alone contains the ‘right’ price. Each trader acts on partial information and personal strategies, yet their collective interaction produces a dynamic system that integrates information from across the globe. Human language evolves through a similar process of emergence. No individual or committee decides that ‘LOL’ should enter common usage or that the meaning of ‘cool’ should expand beyond temperature (even in French-speaking countries). Instead, these changes result from millions of daily linguistic interactions, with new patterns of speech bubbling up from the collective behaviour of speakers.

These examples highlight a key characteristic of highly interconnected systems: the rich interplay of constituent parts generates properties that defy reductive analysis. This principle of emergence, evident across seemingly unrelated fields, provides a powerful lens for examining one of our era’s most elusive mysteries: how the brain works.

The core idea of emergence inspired me to develop the concept I call the entangled brain: the need to understand the brain as an interactionally complex system where functions emerge from distributed, overlapping networks of regions rather than being localised to specific areas. Though the framework described here is still a minority view in neuroscience, we’re witnessing a gradual paradigm transition (rather than a revolution), with increasing numbers of researchers acknowledging the limitations of more traditional ways of thinking.

Complexity science is an interdisciplinary field that studies systems composed of many interacting components whose collective behaviours give rise to collective properties – phenomena that cannot be fully explained by analysing individual parts in isolation. These systems, such as ecosystems, economies or – as we will see – the brain, are characterised by nonlinear dynamics, adaptability, self-organisation, and networked interactions that span multiple spatial and temporal scales. Before exploring the ideas leading to the entangled brain framework, let’s revisit some of the historical developments of the field of neuroscience to set the stage.

In 1899, Cécile and Oskar Vogt, aged 24 and 29 respectively, arrived in Berlin to establish the Neurological Centre, initially a private institution for the anatomical study of the human brain that in 1902 was expanded to the Neurobiological Laboratory, and then the Kaiser Wilhelm Institute for Brain Research in 1914. Cécile Vogt was one of only two women in the entire institute. (In Prussia, until 1908, women were not granted access to regular university education, let alone the possibility to have a scientific career.) She obtained her doctoral degree from the University of Paris in 1900, while her husband Oskar obtained a doctorate for his thesis on the corpus callosum from the University of Jena in 1894.

In 1901, Korbinian Brodmann, who had concluded his doctorate in Leipzig in 1898, joined the group headed by the Vogts and was encouraged by them to undertake a systematic study of the cells of the cerebral cortex using tissue sections stained with a new cell-marking method. (The cortex is the outer brain surface with grooves and bulges; the subcortex comprises other cell masses that sit underneath.) The Vogts, and Brodmann working separately, were part of a first wave of anatomists trying to establish a complete map of the cerebral cortex, with the ultimate goal of understanding how brain structure and function are related. In a nutshell, where does a mental function such as an emotion reside in the brain?

Neurons – a key cell type of the nervous system – are diverse, and several cell classes can be determined based on both their shape and size. Researchers used these properties, as well as spatial differences in distribution and density, to define the boundaries between potential sectors. In this manner, Brodmann subdivided the cortex into approximately 50 regions (also called areas) per hemisphere. The Vogts, in contrast, thought that there might be more than 200 of them, each with its own distinguishing cytoarchitectonic pattern (that is, cell-related organisation).

It Is An Idea That Comes Close To Being An Axiom In Biology: Function Is Tied To Structure

Brodmann’s map is the one that caught on and stuck, likely because neuroanatomists opposed too vigorous a subdivision of the cortex, and today students and researchers alike still refer to cortical parts by invoking his map. Although relatively little was known about the functions of cortical regions at the time, Brodmann believed that his partition identified ‘organs of the mind’ – he was convinced that each cortical area subserved a particular function. Indeed, when he joined the Vogts’ laboratory, they had encouraged him to try to understand the organisation of the cortex in light of their main thesis that different cytoarchitectonically defined areas are responsible for specific physiological responses and functions.

There is a deep logic that the Vogts and Brodmann were following. In fact, it is an idea that comes close to being an axiom in biology: function is tied to structure. In the case at hand, parts of the cortex that are structurally different (contain different cell types, cell arrangements, cell density, and so on) carry out different functions. In this manner, they believed they could understand how function is individuated from a detailed characterisation of the underlying microanatomy. They were in search of the functional units of the cortex – where the function could be sensory, motor, cognitive and so on.

Unlike other organs of the body that have more clear-cut boundaries, the cortex’s potential subdivisions are not readily apparent at a macroscopic level. One of the central goals of many neuroanatomists in the first half of the 20th century was to investigate such ‘organs of the mind’ (an objective that persists to this day). A corollary of this research programme was that individual brain regions – say, Brodmann’s area 17 in the back of the brain – implemented specialised mechanisms, in this case related to processing visual sensory stimuli. Therefore, it was vital to understand the operation of individual parts since the area/region was the rightful mechanistic unit to understand how the nervous system works.

Neuroscientists’ interest in brain regions was motivated by the notion that each region executes a particular function. For example, we could say that the function of the primary visual cortex is visual perception, or perhaps a more basic visual mechanism, such as detecting ‘edges’ (sharp light-to-dark transitions) in images. The same type of description can be applied to other sensory and motor areas of the brain. This exercise becomes considerably less straightforward for brain areas that are much less sensory or motor, as their workings become exceedingly difficult to determine and describe. Nevertheless, in theory, we can imagine extending the idea to all parts of the brain. The result of this endeavour would be a list of area-function pairs: L = {(A1, F1), (A2, F2), … , (An, Fn)}, where areas A implement functions F.

There is, however, a serious problem with this endeavour. To date, no such list has been systematically generated. Indeed, current knowledge strongly suggests that this strategy will not yield a simple area-function list. What may start as a simple (A1, F1) pair, is gradually revised as research progresses, and eventually grows to include a list of functions, such that area A1 participates in a series of functions F1, F2, … , Fk. From a basic one-to-one A1 → F1 mapping, the picture evolves to a one-to-many mapping: A1 → {F1, F2, … , Fk}.

If the mapping between structure and function is not one-to-one, then what kind of system is the brain? This is the question the entangled brain concept sets out to tackle. It’s useful to consider two types of information: anatomical and functional. Let’s start with the brain’s massive combinatorial anatomical connectivity. Neurons are constantly exchanging electrochemical signals with one another. Signalling between them is aided by physical cell extensions, called axons, that protrude beyond the cell body for distances from less than 1 mm to around 15 mm in the central nervous system. Axons travelling longer distances typically bundle together along what are called white-matter tracts to distinguish them from tissue composed of neuronal cell bodies, which is called grey matter. Anatomical connectivity, then, can be viewed as a system of roads and highways that supports cell signalling in the brain.

While most connections are local, the brain also maintains an impressive network of medium- and long-distance pathways. To give a rough sense of the dimensions involved, axonal lengths within local brain circuits (such as those within a single Brodmann area) have lengths from less than 1 mm to just under 1 cm. Connections between adjacent and nearby regions can extend between 0.5 to 4 cm, and connections between areas in different lobes, such as between the frontal and the occipital lobes, can reach 15 cm or more.

Although details vary across mammalian species, there’s evidence that the brains of macaque monkeys (a species that has a brain organisation resembling that of humans) are densely interconnected. For example, when scientists looked at any two regions in the cortex, they found that about 60 per cent of the time there’s a direct connection between them (although the strength of the pathway decreases between regions that are farther apart). Notably, the cortex organises medium- and long-distance communication through special regions that act like major transportation hubs, routing and coordinating signals across the entire cortex, much like how major airports serve as central connection points in the global air transportation network.

But that’s just part of the story. Beyond the extensive interconnections found in the cortex, there are multiple ‘connectional systems’ that weave together regions even further. The entire cortex connects to deeper brain structures. We can think of the brain as having distinct sectors. Simplifying somewhat, these are the cortex, the subcortical parts that are physically beneath the cortex in humans, and the brainstem. In the 1980s, it became clear that the cortex and subcortex are part of extensive connectional loops – from cortex to subcortex back to cortex. We now know that the multiple sectors are amply interlinked. What is more, a subcortical structure such as the thalamus, viewed in the past as a relatively passive steppingstone conveying signals to the cortex, is so sweepingly interconnected with the entire cortex that it is perhaps better to think in terms of a cortical-thalamic system. Even subcortical areas believed to mainly control basic functions, like the hypothalamus, which regulates hunger and body temperature among others, have widespread connections throughout the brain. This creates an incredibly intricate connectional web where signals can travel between disparate parts through multiple routes, hence the idea of ‘combinatorial’ connectivity.

What are the implications of the connectional organisation of the brain? The dense nexus of pathways allows for remarkable flexibility in how the brain processes information and controls behaviour. Signals of all types can be exchanged and integrated in multiple ways. All this potential mixing strongly challenges how we traditionally think of the mind and brain in terms of simplistic labels such as ‘perception’, ‘cognition’, ‘emotion’ and ‘action’. I will return to this point later, but the standard view is further challenged by a second principle of brain organisation: highly distributed functional coordination.

Groups of Neurons That Fire In A Coherent Fashion Indicate That They Are Functionally Interrelated

The Roman Empire’s roads, critical to its success, were extensive enough to circle the globe about twice over. In addition to obvious military applications, the road network supported trade, as well as cultural and administrative integration. These economic and cultural relationships and coordination between disparate parts of the empire were sustained by the incredible physical infrastructure known as the cursus publicus. Likewise, in the brain we need to move beyond the anatomical domain (the roads) to functional properties (such as economic and cultural relationships between different parts of the Roman Empire), all the more because neuroscientists themselves often focus too much on anatomical features.

In the brain, functional relationships between neuronal signals are detected across multiple spatial scales – from the local scale of neurons within a brain area to larger scales involving signals originating from the grey matter of different lobes (such as the frontal and parietal lobes, many centimetres apart). By signals, we mean the electrical activity of neurons that is directly recorded via microelectrodes inserted into grey matter (ie, neuronal tissue), measured indirectly when using functional magnetic resonance imaging (fMRI) in humans, or possibly via other measurement techniques.

What kinds of functional relationships are detected? An important one is that signals from different sites exhibit synchronised neuronal activity. This is notable because groups of neurons that fire in a coherent fashion indicate that they are functionally interrelated, and potentially part of a common process. Different types of signal coordination are believed to reflect processes such as attention and memory, among others. Additional types of relationships are detected mathematically, too, such as whether the strength of the response in one brain area is related to the temporal evolution of signals in a disparate location. In the brain, we identify signal relationships that are indicators of joint functions between regions, much like detecting cultural exchanges between separate parts of the Roman Empire via evidence of shared artefacts or language patterns.

When signals are measured from two sites within a local patch (say, a few millimetres across), it is not too surprising to find notable functional relationships between them (eg, their neuronal activity is correlated), as neurons likely receive similar inputs and are locally connected. Yet, we also observe functional relationships between neuronal signals from locations that are situated much farther apart and, critically, between brain parts that are not directly anatomically connected – there is no direct axonal connection between them.

How does this happen? There is evidence that signal coordination between regions depends more on the total number of possible communication routes between them than on the existence of direct connections between points A and B. For example, although regions A and B are not anatomically connected, they both connect to region C, which thus serves as a bridge between them. Even more circuitous paths can unite A and B, much like flying between two cities that have no direct flights and require multiple layovers. In such a manner, the brain creates functional partnerships that take advantage of all possible ways through its intricate pathways. This helps explain how the brain can be so remarkably flexible, sustaining different partnerships between regions depending on what we’re doing, thinking or feeling at any given moment.

When we consider the highways traversing the brain and how signals establish behaviourally relevant relationships across the central nervous system, we come to an important insight. In a highly interconnected system, to understand function, we need to shift away from thinking in terms of individual brain regions. The functional unit is not to be found at the level of the brain area, as commonly proposed. Instead, we need to consider neuronal ensembles distributed across multiple brain regions, much like the murmuration of starlings forms a single pattern from the collective behaviour of individual birds.

There are many instances of distributed neuronal ensembles. Groups of neurons extending over cortical (say, prefrontal cortex and hippocampus) and subcortical (say, amygdala) regions form circuits that are important for learning what is threatening and what is safe. Such multiregion circuits are ubiquitous; fMRI studies in humans have shown that the brain is organised in terms of large-scale networks that stretch across the cortex as well as subcortical territories. For example, the so-called ‘salience network’ (suggested to be engaged when significant events are encountered) spans brain regions in the frontal and parietal lobes, among others, and can also be viewed as a neuronal ensemble.

Whether we consider ensembles in the case of brain circuits or large-scale networks, the associated neuronal groupings should be viewed as strongly context dependent and dynamic. That is to say, they are not fixed entities but instead form dynamically to meet current situational requirements. Accordingly, they will dynamically assemble and disassemble as per behavioural needs. The implication of this view is that whereas brain regions A, B and C might generally be active together in dealing with a specific type of behaviour, in some contexts, we will also observe an ensemble that encompasses region D, or instead the ensemble {A, C, D} that meets slightly different requirements. In all, neuronal ensembles constitute an extremely malleable functional unit.

Think of how an orchestra works during a complex piece of music. The string section might split into different groups, with some violins joining the woodwinds for one musical phrase while others harmonise with the cellos. Later, these groupings shift completely for a different passage. The brain works in a related way: rather than recruiting fixed regions, it forms flexible aggregations that assemble and disassemble based on what we’re doing, thinking or feeling. This builds on what we learned about the brain’s extensive physical connections and the coordinated activity across regions. These features make the formation of ensembles possible.

Brain Regions Can Participate In Multiple Networks Simultaneously And Shift Their Roles As Needed

As is common in science, these ideas have a long genealogy. In 1949, the Canadian psychologist Donald Hebb proposed that the brain’s ability to generate coherent thoughts derives from the spatiotemporal orchestration of neuronal activity. He hypothesised that a discrete, strongly interconnected group of active neurons called the cell assembly represents a distinct mental entity, such as a thought or an emotion. Yet, these ideas have taken a long time to mature, not least due to technical limitations in measuring signals simultaneously across the brain, and the relative insularity of experimental neuroscience from other disciplines, such as computer science, mathematics and physics.

Just as a symphony emerges from both the individual instruments and how they play together, brain function emerges from both the regions themselves and their dynamic interactions. Scientists are finding that we can’t understand complex mental processes by studying individual brain regions in isolation, any more than we could understand a symphony by listening to each instrument separately.

What’s particularly fascinating is that these brain assemblages overlap and change over time. Just as a violin might be part of the string section in one moment and join a smaller ensemble in the next, brain regions can participate in multiple networks simultaneously and shift their roles as needed. But note that, in this view, even brain networks aren’t seen as constituted of fixed sets of regions; instead, they are dynamic coalitions that form and dissolve based on the brain’s changing needs. This flexibility helps explain how the brain can support such a wide range of complex behaviours using a limited number of regions.

Categories such as perception, cognition, action, emotion and motivation are not only the titles of introductory textbooks, but reflect how psychologists and neuroscientists conceptualise the organisation of the mind and brain. They seek to subdivide the brain into territories that have preferences for processes that support a specific type of mental activity. Some parts handle perception, such as the back of the head and its involvement in vision, or the front of the brain and its role in cognition. And so on. The decomposition of the mind-brain adopted by many neuroscientists follows an organisation that is called modular. Modularity here refers to the idea that the brain consists of specialised, relatively independent components or modules that each handle specific mental functions, much like distinct parts in a machine that work together but perform separate operations.

Yet, a modular organisation, popular as it is among neuroscientists, is inconsistent with the principles of the anatomical and functional neuroarchitecture discussed here. The brain’s massive combinatorial connectivity and highly distributed functional coordination defy clean compartmentalisation. The extensive bidirectional pathways spanning the entire brain create crisscrossing connectional systems that dissolve potential boundaries between traditional mental domains (cognition, emotion, etc).

Anxiety, PTSD, Depression And So On Should Be Viewed As System-Level Entities

Brain regions dynamically affiliate with multiple networks in a context-dependent manner, forming coalitions that assemble and disassemble based on current demands. This interactional complexity means that functions aren’t localised to discrete modules but emerge from decentralised coordination across multiregion assemblies. The properties that emerge from these interactions cannot be reduced to individual components, making a strict modular framework inadequate for capturing the brain’s entangled nature.

Why is the brain so entangled, and thus so unlike human-engineered systems? Brains have evolved to provide adaptive responses to challenges faced by living beings, promoting survival and reproduction – not to solve isolated cognitive or emotional problems. In this context, even the mental vocabulary of neuroscience and psychology (attention, cognitive control, fear, etc), with origins disconnected from the study of animal behaviour, provides problematic theoretical pillars. Instead, approaches inspired by evolutionary considerations provide better scaffolds to sort out the relationships between brain structure and function.

The implications of the entangled brain are substantial for the understanding of healthy and unhealthy brain processes. It is common for scientists to seek a single, unique source of psychological distress. For example, anxiety or PTSD is the result of an overactive amygdala; depression is caused by deficient serotonin provision; drug addiction is produced by dopamine oversupply. But, according to the ideas described here, we should not expect unique determinants for psychological states.

Anxiety, PTSD, depression and so on should be viewed as system-level entities. Alterations across several brain circuits, spanning multiple brain regions, are almost certainly involved. As a direct consequence, healthy or unhealthy states should not be viewed as emotional, motivational or cognitive. Such classification is superficial and neglects the intermingling that results from anatomical and functional brain organisation.

We should also not expect to find a single culprit, not even at the level of distributed neuronal ensembles. The conditions in question are too heterogeneous and varied across individuals; they won’t map to a single alteration, including at the distributed level. In fact, we should not expect a temporally constant type of disturbance, as brain processes are highly context-dependent and dynamic. Variability in the very dynamics will contribute to how mental health experiences are manifested.

In the end, we need to stop seeking simple explanations for complex mind-brain processes, whether they are viewed as healthy or unhealthy. That’s perhaps the most general implication of the entangled brain view: that the functions of the brain, like the murmurations of starlings, are more complicated and more mysterious than its component parts.

[unstableconnection]

I’ve recently begun to think of myself as a configuration of the universe. Nothing more than information. Made up of the same hydrogen that has existed since three minutes after the Big Bang, 83% of my body composed of carbon and oxygen forged in the hearts of stars billions of years ago. And what about this awareness? This perception of reality? Is that also a side effect of the physical universe, or is consciousness just my means to an experience?

We think of ourselves as these physical expressions on earth, housed in the box that is the cosmos and the universe in its entirety, but I think we’re just merely expressions of that universe. Not separate entities but a form of potential. The result of an evolution of the most primitive particles.

Am I wrong to think then that it must mean, just for a little while, this vast and indifferent universe is not just expanding but thinking and feeling…

The body, we know, is a temporary arrangement. But what if the awareness we have that we think makes us special is just a temporally sustained pattern of coherence. Not a souls in the traditional sense, but a ripple of information held just long enough.

Not just an agent in time but the very unfolding of time, where information turns inward and becomes aware of itself. Maybe that’s why we perceive time so linearly when time itself isn’t linear at all. To be conscious is to be suspended in a state of comparison, to feel the world as a difference unfolding and constantly comparing one moment to the last. Noticing change, holding onto that difference, a series of frames of reference.

I think there’s something primordial in this concept. Consciousness as complex information systems that has evolved to detect patterns, impose structure and survive.

If consciousness then is the byproduct of complex informational systems, what did it begin as. We often think of it born out of nothing, a divine power given to us special humans whom can use it to reason and to love… and to hate. Poetic and self-reflective. I don’t think it came from nothing. It must have began as just a mechanism. A flicker of responsiveness in a hostile world. A cell noticing light. A molecule reacting to heat.

It’s adaptive, a tool for survival. To process information and react — the very first “experience.”

To sense the environment. To distinguish pain from safety. Pattern from noise. Self from other. But over time and through billions of iterations it became memory. Imagination. Anticipation.

And eventually, us — aware not only of our environment, but of our awareness itself.

Is that where meaning then comes from?

Life feeds on this idea of negative entropy, pockets of increasing order siphoned off from a universe otherwise governed by disorder.

And consciousness, in turn, is maybe what happens when information, looped back on itself, becomes aware of its own contingency.

We are the outcome of that loop.

This is in and of itself absolutely absurd. In our endless search for meaning in every crevice of the physical and metaphysical world, are we just caught in this loop searching for something that never existed in the first place?

Then what? Where do you go from here.

Still, you want it all to matter. We want life to matter. We dig through the dirt looking for something solid. We invent gods, write books, drink. We fall in love and pretend there's some higher thread tying it all together, because the alternative — that it���s just noise — is too much some nights.

But even if it is just noise, we’re still here. Still breathing, still thinking, still choosing. And that I think counts for something. To know the void is real and to spit in it. I think it’s the whole point.

So I’ll wake up tomorrow. I’ll drink my coffee. I’ll write my name on a page and maybe tell someone I love them, or scream… because I can. And maybe just knowing this house is rigged, but playing the game anyway is enough. Not to win. But just to sit down and play. For however long the game lasts.

From stardust to stardust.

The Acoustic Weapon: How the Cello Dominates Contemporary Music

Few instruments in the musical world hold the same emotive power as the cello. Revered for its warm, resonant tones and wide expressive range, the cello has journeyed from the courts of the Baroque era to modern-day concert halls, film scores, and even experimental soundscapes. While its classical heritage remains rooted in history, the instrument continues to evolve in construction, application, and cultural relevance.

The Cello’s Rich Historical Footprint

The cello, short for violoncello, was born in 16th-century Italy. It was initially used to support the bass lines of ensembles, functioning as a companion to the violin and viola. Over time, its unique tonal depth earned it a soloist’s reputation, especially during the Baroque and Classical periods. Composers like Bach and Haydn wrote extensively for the cello, solidifying its prominence in chamber and orchestral settings.

Its structure underwent subtle refinements through the centuries. Earlier models were larger and featured gut strings, which produced a mellow tone but lacked the projection modern musicians required. With the rise of concert venues and the shift toward more powerful performances, the cello adopted steel strings and sturdier construction. Today, many cellists play on carbon fibre models as a modern, lightweight alternative to traditional wood.

A Sound That Transcends Genres

What sets the cello apart is its remarkable emotional versatility. Its range, roughly spanning four octaves, mirrors the human voice. This allows it to convey melancholy, joy, serenity, or turbulence with striking clarity. The cello’s sound is warm and rich in its lower register, while its upper notes can be strikingly lyrical.

Its place in modern music has grown remarkably. From classical performances and solo recitals to pop, jazz, and even electronic collaborations, the cello’s voice finds relevance in a variety of contexts. Artists like 2Cellos and Yo-Yo Ma have brought the instrument to mainstream audiences, using it to cover rock anthems, film themes, and folk music, showing its adaptability across genres.

A recent trend is the increasing use of the cello in digital composition and music production. Music producers now incorporate their layers into cinematic scores and ambient soundtracks. The emotive timbre of the cello adds depth to music that seeks to stir the soul. Sample libraries and digital plug-ins now offer virtual cello recordings, making it accessible to composers worldwide.

Even for students and emerging performers, cello insurance can ensure peace of mind. It covers repairs and replacements, especially for rented or borrowed instruments. Some policies extend to international travel, an essential feature for touring cellists.

Caring for a Cello in the Modern World

While the cello’s sound can last generations, the instrument itself requires careful maintenance. From environmental factors like humidity to physical damage during transport, a cello’s lifespan is heavily influenced by how it’s stored and handled. As professional performances and travel demands grow, so do the risks.

One crucial aspect for modern musicians is safeguarding their instruments with the right protection. While many opt for hard-shell cases and climate-controlled storage, an increasing number are recognizing the importance of specialized coverage. Reliable cello insurance provides financial protection against accidental damage, theft, or loss. Considering the high value of certain instruments—some cellos crafted by historic luthiers can fetch millions—such coverage becomes more than a precaution.

A Legacy That Continues to Evolve

The cello remains a bridge between centuries of tradition and modern innovation. Its role in contemporary music continues to expand, echoing its capacity to adapt and inspire. Whether in the hands of a classical soloist or a digital composer, the cello’s voice remains timeless and evocative.

To play the cello is to participate in a legacy shaped by history, yet open to constant reinvention and rediscovery. With the right care, maintenance, and protection, artists and instruments are well-positioned to keep this legacy alive, relevant, and cherished by audiences for generations to come.

The Last Architecture: Leukomorphs

Nearly lost within the gloom ahead, a shadow shifts and parts from its fellows, the motion setting off a varied iridescence that shimmers across its obscure mass.

Responding to your presence, this flowing patchwork of viscous darkness draws closer, an unravelling of sinewy membrane from an articulated carapace that dazzles you with colour as the creature reaches blindly toward you.

It wasn’t a thing that moved but a reconfiguration of the air itself, a seizure in the visible spectrum, the light around it thickening, splitting into oily ribbons where it passed.

Though your eyes said liquid, your skin said metal, your bones said alive as it folded like crushed velvet over glass and where it touched the wound, your blood moved wrong, not dripping, but threading itself into the creature’s grasp, engulfing you.

Becoming you.

Average Height: 0.5 – 2 m / 1.5’ – 6’ (stretches/shrinks based on host)

Blood Colour: N/A

Lifespan: Indefinite (if they keep finding hosts; otherwise, they desiccate into inert silica).

Skin Colours: N/A

Hair Textures: N/A

Hair Colours: N/A

Eye Colours: N/A

Population Percentage: 0.7% (most are bonded; few remain "wild").

An enigmatic race of biomimetic polymorphs which must genetically bond as neural symbionts to a host body in order to survive and evolve, they are neither independent organisms nor mere tools, existing as parasitic augmentations that rewrite their hosts at the atomic level, evolutionary catalysts merging with them to create hybridized lifeforms. Comparable to a living biomechanical interface, leukomorphs possess the ability to fuse their own diaphanous neurology with the nervous systems of host bodies at the atomic level, weaving their fluidic musculature throughout and essentially rendering them an extension of the host, functioning much as an entirely new appendage.

Their common name, “Nyrrith”, is derived from this very process, the word being derived from the sounds experienced by the host during bonding, described like that of glass scraping bone. Among themselves, they share no words, instead self-identifying with conception shared via bioelectric pulses which are ultimately untranslatable to other peoples understood by their hosts as a vague yet singular feeling.

The tough, resinous skin of the leukomorph is composed of layered protein polysaccharides akin to bioplastic, interlaced with polarised organic silicon that appears milky white when shown with bright light, these dense, metal-bonded molecular structures functioning much like living solid-state circuitry. Layered membranes of chromatically adaptive cells act both as muscles and neurons, allowing leukomorphs to pattern the flexible monofilaments which comprise their dense, spongy biomass into useful structural configurations of colour, texture, shape or solidity.

In combat, they can harden into dense, armoured structures, sharpen extensions of themselves into monofilament blades or diffuse into a conductive mist capable of channelling atmospheric plasma with devastating effect. The latter is also how they feed, for although they can subsist on the energy produced by the chemical processes which drive the processes within the living cells of their host, this can be very draining to the host body, even lethal.

With almost no tactile sensitivity and poor visual acuity, limited to differences in light and shadow, leukomorphs rely mostly on highly specialised thermoreceptors spread in small clusters across their bodies to sense and track sources of infrared radiation. These, paired alongside electroreceptors, can track the presence and pattern of heat differentials, electric currents and magnetic fields, the latter being sensitive enough to perceive surface-level neural and muscle activity in living things, predicting reactions and intent.

Microscopic barbs coating their outer layer allow them to stick to just about anything and render them impossible to remove without killing a host, the bond itself resulting in something like a low-level empathic interface, bypassing logic. This allows them to react to the host’s desires before the host is consciously aware and, acting in concert, the host is able to process stimuli while the leukomorph moves itself and/or the body to react with increased proficiency and reveal attributes and abilities unique to both.

This also serves as their chief form of communication as, while intelligent, leukomorphs are incapable of vocalisations and instead communicate only through vague impressions of desires and bluntly intense emotions transmitted directly to their host. In this way, the pair come together as a new gestalt personality that combines the strongest traits gathered from any previous hosts with that of the current, allowing the race to continually evolve and adapt across generations without the need to actively teach.

For leukomorphs, it is the exchange and cultivation of experiences between hosts that comprises the closest thing they have to culture, albeit one which is atomised across innumerable individuals in a loose network of bonded pairs who trade hosts to diversify their genetic memory. In rare cases, these pseudo-lineages will gather to merge themselves into a single composite mass, passing on experiences and adaptations before emerging again as wholly new entities, in greater numbers, their equivalent of reproduction.

Chapter: Omega-3 and Brain Expansion – The Evolutionary Role of DHA

by UEVS and the power of AI

Introduction

The human brain is one of the most metabolically demanding organs in the body, consuming about 20% of total energy despite accounting for only 2% of body weight. Its evolution into the complex structure we see today was driven by a combination of genetic adaptations, environmental pressures, and crucially, dietary shifts. Among the most important dietary factors was the intake of omega-3 fatty acids, particularly docosahexaenoic acid (DHA).

DHA is an essential structural lipid in the brain, influencing neuronal plasticity, synaptic function, and cognitive abilities. The hypothesis that DHA-rich diets played a key role in human brain expansion has gained significant scientific support (Cunnane, 2005; Crawford, 2010; Bradbury, 2011).

How Much DHA is in the Human Brain?

The human brain is composed of about 60% fat, and DHA accounts for approximately 10-20% of the brain’s total fatty acid content. It is highly concentrated in gray matter, neuronal membranes, and synaptic terminals, where it is critical for:

Membrane Fluidity: Ensuring optimal neurotransmission and signal transduction.

Neuronal Growth: Supporting neurogenesis and dendritic complexity.

Cognitive Function: Enhancing memory, problem-solving, and learning abilities.

DHA Distribution in the Brain

Gray Matter: The highest concentrations of DHA are found in the prefrontal cortex, hippocampus, and cerebral cortex—regions responsible for higher-order cognition, decision-making, and memory.

Synaptic Membranes: DHA is integrated into phospholipids of neuronal cell membranes, increasing synaptic fluidity and efficiency.

Myelin Sheath: It contributes to the insulation of neurons, enhancing neuronal communication speed.

The estimated total DHA content in an adult human brain is around 5-10 grams, depending on diet and metabolic factors.

The Role of DHA in Brain Evolution

1. The Shift Toward Omega-3-Rich Diets

The human lineage diverged from chimpanzees about 5-7 million years ago, and over time, hominins evolved larger brains. However, brain expansion accelerated significantly in the last 2 million years, particularly with the emergence of Homo erectus (~1.9 million years ago). This period coincided with changes in diet that included aquatic and coastal food sources.

2. The “Coastal Hypothesis” and DHA Availability

The Shore-Based Hypothesis (Cunnane et al., 2005) suggests that access to marine life, freshwater fish, and shellfish provided high levels of DHA, which became a key driver of brain expansion. Early hominins living near rivers, lakes, and coastal areas had an evolutionary advantage because:

DHA-Rich Diets Supported Rapid Brain Growth Marine and freshwater food sources are naturally abundant in DHA and EPA, which terrestrial-based diets lack.

More Efficient Energy Use for the Brain DHA optimizes neuronal ATP production and mitochondrial function, reducing oxidative stress in the brain.

Superior Cognitive and Social Abilities With improved hand-eye coordination, memory, and communication skills, DHA-supported brains led to better survival strategies, tool-making, and social cooperation.

Additionally, some inland hominins may have obtained DHA from sources such as organ meats, algae, and wild game, although these were likely less abundant compared to aquatic sources.

3. DHA and the Rapid Brain Expansion of Homo Sapiens

The Homo sapiens brain (~1,400 cm³) is about three times larger than that of our early ancestors. This expansion, known as encephalization, is thought to have been fueled by access to high-quality, DHA-rich nutrition.

Neural Connectivity: DHA promotes synaptogenesis, improving cognitive function.

Memory and Learning: High DHA levels in the hippocampus enhance memory retention and problem-solving skills.

Social Intelligence: The ability to process emotions and maintain complex social structures is enhanced by DHA-mediated neurotransmission.

DHA in Pregnancy and Early Development

DHA is particularly crucial during fetal brain development and infancy. The human brain undergoes rapid growth in the last trimester of pregnancy and the first two years of life, often referred to as the "brain growth spurt."

Maternal DHA Intake: A mother’s diet directly impacts fetal DHA levels. Pregnant women consuming DHA-rich foods or supplements tend to have children with higher cognitive abilities and better attention spans.

Breastfeeding and DHA: Human breast milk naturally contains DHA, further supporting neurodevelopment and visual acuity in infants.

Conclusion and Call to Action

The role of DHA in human brain evolution and function cannot be overstated. From its crucial role in fetal development to its continued necessity for cognitive function and mental health, DHA remains an essential nutrient for optimizing brain performance and longevity. As modern diets increasingly shift away from natural sources of DHA, it is vital to restore the balance of omega-3s to sustain the cognitive advantages that set Homo sapiens apart.

To enhance brain health and overall well-being:

Incorporate more DHA-rich foods such as fatty fish (salmon, mackerel, sardines) or algae-based supplements for plant-based diets.

Reduce excessive omega-6 intake by avoiding processed seed oils and highly refined foods.

Stay informed and make conscious dietary choices to support not only cognitive function but also long-term neuroprotection against degenerative diseases.

By making DHA a priority in your nutrition, you are investing in the foundation of human intelligence, adaptability, and longevity.

Travel broadens the mind. How far do you agree ? (Make sure you mention personal experiences)

Travel has long been celebrated for its ability to broaden the mind, and I wholeheartedly agree with this sentiment. The experience of visiting new places and encountering different cultures fosters personal growth and a deeper understanding of the world.

Firstly, travel exposes individuals to diverse perspectives. When we step outside our familiar environments, we interact with people whose backgrounds, beliefs, and lifestyles may differ vastly from our own. This interaction encourages empathy and cultural awareness, as we learn to appreciate the nuances of others’ experiences. For instance, dining with locals in a foreign country or participating in traditional festivities can provide insights into values and customs that are often taken for granted in one’s own culture.

Additionally, travel encourages adaptability and problem-solving skills. Navigating unfamiliar places often involves overcoming challenges, such as language barriers or unexpected changes in plans. These experiences foster resilience and the ability to think critically, skills that are valuable in both personal and professional realms.

Moreover, exposure to different landscapes, art forms, and histories can inspire creativity and new ways of thinking. Visiting ancient ruins, natural wonders, or renowned museums stimulates curiosity and often leads to a deeper appreciation for human achievement and the environment. Such experiences can ignite passions and interests that one may not have encountered otherwise.

In conclusion, the idea that travel broadens the mind is supported by the rich array of experiences and lessons it offers. By embracing new cultures, overcoming challenges, and engaging with diverse perspectives, travellers often return home with a more profound understanding of themselves and the world around them. Thus, travel not only enriches individual lives but also cultivates a more interconnected and compassionate global community.
