Friday Thinking 5 Feb 2021

Friday Thinking is a humble curation of my foraging in the digital environment. Choices are based on my own curiosity and that suggest we are in the midst of a change in the conditions of change - a phase-transition. That tomorrow will be radically unlike yesterday.

Many thanks to those who enjoy this.
In the 21st Century curiosity is what skills the cat -
for life of skillful means .
Jobs are dying - Work is just beginning.
Work that engages our whole self becomes play that works.

The emerging world-of-connected-everything - digital environment - 
computational ecology - 
may still require humans as the consciousness of its own existence. 

To see red - is to know other colors - without the ground of others - there is no figure - differences that make a defference.

If value is defined by price – set by the supposed forces of supply and demand – then as long as an activity fetches a price (legally), it is seen as creating value. So if you earn a lot you must be a value creator. I will argue that the way the word ‘value’ is used in modern economics has made it easier for value-extracting activities to masquerade as value-creating activities. And in the process rents (unearned income) get confused with profits (earned income); inequality rises, and investment in the real economy falls. What’s more, if we cannot differentiate value creation from value extraction, it becomes nearly impossible to reward the former over the latter. If the goal is to produce growth that is more innovation-led (smart growth), more inclusive and more sustainable, we need a better understanding of value to steer us.

Takers and Makers: Who are the Real Value Creators?



Mass opposition to the politics of humiliation began from the early 19th century in Europe, as lower-class people increasingly objected to disrespectful treatment. Servants, journeymen and factory workers alike used the language of honour and concepts of personal and social self-worth – previously monopolised by the nobility and upper-middle classes – to demand that they not be verbally and physically insulted by employers and overseers.

This social change was enabled and supported by a new type of honour that followed the invention of ‘citizens’ (rather than subjects) in democratising societies. Citizens who carried political rights and duties were also seen as possessing civic honour. Traditionally, social honour had been stratified according to status and rank, but now civic honour pertained to each and every citizen, and this helped to raise their self-esteem and self-consciousness. Consequently, humiliation, and other demonstrations of the alleged inferiority of others, was no longer considered a legitimate means by which to exert power over one’s fellow citizens.

The history of humiliation points to the future of human dignity




humans have often understood the nervous system in terms of the flourishing technologies of their era, as the scientist and historian Matthew Cobb explained in The Idea of the Brain (2020). Thomas Hobbes, in his book Leviathan (1651), likened human bodies to ‘automata’, ‘[e]ngines that move themselves by springs and wheeles as doth a watch’. What is the heart, Hobbes asked, if not ‘a Spring; and the Nerves, but so many Strings …?’ Similarly, Descartes described animal spirits moving through the nerves according to the same physical properties that animated the hydraulic machines he witnessed on display in the French royal gardens.

The rise of electronic communications systems accelerated this trend. In the middle of the 19th century, the surgeon and chemist Alfred Smee said the brain was made up of batteries and photovoltaic circuits, allowing the nervous system to conduct ‘electro-telegraphic communication’ with the body. Towards the turn of the 20th century, the neuroscientist Santiago Ramón y Cajal described the positioning of different neural structures ‘somewhat as a telegraph pole supports the conducting wire’. And, during the First World War, the British Royal Institution Christmas lectures featured the anatomist and anthropologist Arthur Keith, who compared brain cells to operators in a telephonic exchange.

The technologies that have come to dominate many of our lives today are not primarily hydraulic or photovoltaic, or even telephonic or electro-telegraphic. They’re not even computational in any simplistic sense. They are predictive, and their infrastructures construct and constrain behaviour in all spheres of life. The old layers remain – electrical wiring innervates homes and workplaces, and water flows into sinks and showers through plumbing hidden from view. But these infrastructures are now governed by predictive technologies, and they don’t just guide the delivery of materials, but of information. Predictive models construct the feeds we scroll; they autocomplete our texts and emails, prompt us to leave for work on time, and pick out the playlists we listen to on the commute that they’ve plotted out for us. Consequential decisions in law enforcement, military and financial contexts are increasingly influenced by automated assessments spat out by proprietary predictive engines.

John B Watson, a founder of behaviourist psychology in the early 20th century, argued that his discipline’s ‘theoretical goal is the prediction and control of behaviour’ – in service of the needs of ‘the educator, the physician, the jurist, and the businessman’.

the mission of nearly every corporation. Collect data. Write code: if/then/else. Detect patterns. Predict behaviour. Direct action. Encourage consumption. Influence elections.

The problem with prediction




The Kafkaesque aspect of Gödel’s work and character is expressed in his famous Incompleteness Theorem of 1930. Although this theorem can be stated and proved in a rigorously mathematical way, what it seems to say is that rational thought can never penetrate to the final, ultimate truth. A bit more precisely, the Incompleteness Theorem shows that human beings can never formulate a correct and complete description of the set of natural numbers, {0, 1, 2, 3, . . .}. But if mathematicians cannot ever fully understand something as simple as number theory, then it is certainly too much to expect that science will ever expose any ultimate secret of the universe.

Scientists are thus left in a position somewhat like K. in The Castle. Endlessly we hurry up and down corridors, meeting people, knocking on doors, conducting our investigations. But the ultimate success will never be ours. Nowhere in the castle of science is there a final exit to absolute truth.

Memories of Kurt Gödel



Manrubia’s group was discovering a depressing reality: The peak of an epidemic could never be estimated until it happened; the same was true for the end of the epidemic. Work in other labs has similarly shown that attempting to predict plateaus in the epidemic curve over the long term is just as fruitless. One study found that researchers shouldn’t even try to estimate a peak or other landmark in a curve until the number of infections is two-thirds of the way there.

“People say, ‘I can reproduce the past; therefore, I can predict the future,’” Manrubia said. But while “these models are very illustrative of the underlying dynamics … they have no predictive power.”

The Hard Lessons of Modeling the Coronavirus Pandemic






This is an important article by Cory Doctorow and the Electronic Frontier Foundation - signaling that we remain at a tipping point about the governance of the digital environment.
Wise kings are great in theory, but in practice, they are just as fallible as any dunderhead. When the platform gets it wrong, you should be able to pick up and leave -- and still reach your friends, show and sell your art, and advocate for your causes.

Twitter and Interoperability: Some Thoughts From the Peanut Gallery

Late in 2019, Twitter CEO Jack Dorsey floated "Project Blue Sky," a plan for an interoperable, federated, standardized Twitter that would let users (or toolsmiths who work on behalf of users) gain more control over their participation in the Twitter system. This was an exciting moment for us, a significant lurch towards an interoperable, decentralized social media world. We were especially excited to see Dorsey cite Mike Masnick's excellent Protocols, Not Products paper.

It’s been more than a year, and Twitter has marked its progress with an “ecosystem review” that sets out its view of the landscape of distributed systems. The world is a very different place today, with social media playing a very different role in 2021 than it played in 2019. Locked down, with the legitimacy of the US political system under threat, with social media moderation policies taking on national significance, the question of how a federated, decentralized internet would work has become even more salient...and urgent.
Broadly speaking, there are two broad approaches: the first is to fix the tech giants and the second is to fix the Internet.

The advocates for fixing Big Tech are implicitly saying that the net is a fait accompli, with the tech giants destined to reign over all forever. Fixing Big Tech means demanding that these self-appointed dictators be benevolent dictators, that the kings be wise kings. 

By contrast, the fix-the-Internet people want a dynamic Internet, where there are lots of different ways of talking to your friends, organizing a political movement, attending virtual schools, exchanging money for goods and services, arguing about politics and sharing your art.


Now this is a great signal of the urban future - not only for maintaining the subterranean infrastructure - but imagine a swarm of bots geared to keep city streets, sidewalks and more importantly driveway entrances and driveways clear of snow? 

An army of sewer robots could keep our pipes clean, but they'll need to learn to communicate

Hidden from sight, under the UK's roads, buildings and parks, lies about one million kilometers of pipes. Maintaining and repairing these pipes require about 1.5 million road excavations a year, which causes either full or partial road closures. These works are noisy, dirty and cause a lot of inconvenience. They also cost around £5.5 billion a year.

It doesn't have to be this way. Research teams like mine are working on a way of reducing the time and money that goes into maintaining pipes, by developing infrastructure robots.

In the future, these robots will work around and for us to repair our roads, inspect our water and sewer pipes, maintain our lamp posts, survey our bridges and look after other important infrastructure. They will be able to go to places difficult or dangerous for humans, such as sewer pipes full of noxious gases.


This is another signal of a common science fiction theme - nanobots augmenting our biology.
"External-field-induced robots are an attractive concept because they do not require an onboard power supply or intricate moving parts, which means that they can be scaled down to nanometer-sized resolution" Ahmed said. "In addition, both acoustic and magnetic fields are safe for humans, are non-invasive, can penetrate deeply into the human body, and are well-developed in clinical settings."

Tiny bio-inspired swarm robots for targeted medical interventions

Micro-sized robots could bring a new wave of innovation in the medical field by allowing doctors to access specific regions inside the human body without the need for highly invasive procedures. Among other things, these tiny robots could be used to carry drugs, genes or other substances to specific sites inside the body, opening up new possibilities for treating different medical conditions.

Researchers at ETH Zurich and Helmholtz Institute Erlangen–Nürnberg for Renewable Energy have recently developed micro and nano-sized robots inspired by biological micro-swimmers (e.g., bacteria or spermatozoa). These small robots, presented in a paper published in Nature Machine Intelligence, are capable of upstream motility, which essentially means that they can autonomously move in the opposite direction to that in which a fluid (e.g., blood) flows. This makes them particularly promising for intervening inside the human body.

"We believe that the ideas discussed in our multidisciplinary study can transform many aspects of medicine by enabling tasks such as targeted and precise delivery of drugs or genes, as well as facilitating non-invasive surgeries," Daniel Ahmed, lead author of the recent paper, told TechXplore.


This is a good signal of the future of sensors.

Sensors, the other quantum revolution

Medicine, civil engineering, telecommunications, natural resources management... Quantum sensors offering both unique sensitivity and accuracy are about to revolutionise detection in a number of fields.
Identifying every pipe and cavity beneath our cities, anticipating a volcanic eruption, or observing brain activity in the most minute detail, these are only some of the tantalising promises made by a new type of instrument with unprecedented sensitivity: quantum sensors. Of all the quantum technologies under development, they are among the most advanced, with some even emerging from the laboratory and reaching the market! 


Some advances in basic science research as well as a large range of communications may loom soon.

Record-breaking laser link could provide test of Einstein's theory

In a study published today in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre for Space Studies (CNES) and the French metrology lab Systèmes de Référence Temps-Espace (SYRTE) at Paris Observatory.

The result is the world's most precise method for comparing the flow of time between two separate locations using a laser system transmitted through the atmosphere.

"If you have one of these optical terminals on the ground and another on a satellite in space, then you can start to explore fundamental physics," he said. "Everything from testing Einstein's theory of general relativity more precisely than ever before, to discovering if fundamental physical constants change over time."

The technology's precise measurements also have practical uses in earth science and geophysics. "For instance, this technology could improve satellite-based studies of how the water table changes over time, or to look for ore deposits underground," Dr. Schediwy said.

There are further potential benefits for optical communications, an emerging field that uses light to carry information. Optical communications can securely transmit data between satellites and Earth with much higher data rates than current radio communications.


Another fascinating signal of the possibility of advances in fundamental theory of physics - it also signals the significant effort we have to take to not unconsciously skew results - even in physics.
To avoid subconsciously steering the frequency toward the value they want, the experimenters blind themselves to the true frequency until they’ve finalized their analysis.

The cloak-and-dagger tale behind this year’s most anticipated result in particle physics

As early as March, the Muon g-2 experiment at Fermi National Accelerator Laboratory (Fermilab) will report a new measurement of the magnetism of the muon, a heavier, short-lived cousin of the electron. The effort entails measuring a single frequency with exquisite precision. In tantalizing results dating back to 2001, g-2 found that the muon is slightly more magnetic than theory predicts. If confirmed, the excess would signal, for the first time in decades, the existence of novel massive particles that an atom smasher might be able to produce, says Aida El-Khadra, a theorist at the University of Illinois, Urbana-Champaign. “This would be a very clear sign of new physics, so it would be a huge deal.”

The measures that g-2 experimenters are taking to ensure they don’t fool themselves into claiming a false discovery are the stuff of spy novels, involving locked cabinets, sealed envelopes, and a second, secret frequency known to just two people, both outside the g-2 team. “My wife won’t pick me for responsible jobs like this, so I don’t know why an important experiment did,” says Joseph Lykken, Fermilab’s chief research officer, one of the keepers of the secret.


The cultivation of many types of food is ages old - but with the domestication of DNA we can look forward to a new sense of ‘processed meats’ - including the cultivated hot dog.

Researchers create new form of cultivated meat

McMaster researchers have developed a new form of cultivated meat using a method that promises more natural flavor and texture than other alternatives to traditional meat from animals.

Researchers Ravi Selvaganapathy and Alireza Shahin-Shamsabadi, both of the university's School of Biomedical Engineering, have devised a way to make meat by stacking thin sheets of cultivated muscle and fat cells grown together in a lab setting. The technique is adapted from a method used to grow tissue for human transplants.

The sheets of living cells, each about the thickness of a sheet of printer paper, are first grown in culture and then concentrated on growth plates before being peeled off and stacked or folded together. The sheets naturally bond to one another before the cells die.


This a great signal for many older men - but also of new forms of diagnostic testing.

Cancer can be precisely diagnosed using a urine test with artificial intelligence

Prostate cancer is one of the most common cancers among men. Patients are determined to have prostate cancer primarily based on PSA, a cancer factor in blood. However, as diagnostic accuracy is as low as 30%, a considerable number of patients undergo additional invasive biopsy and thus suffer from resultant side effects, such as bleeding and pain.

The Korea Institute of Science and Technology (KIST) announced that the collaborative research team led by Dr. Kwan Hyi Lee from the Biomaterials Research Center and Professor In Gab Jeong from Asan Medical Center developed a technique for diagnosing prostate cancer from urine within only 20 minutes with almost 100% accuracy. The research team developed this technique by introducing a smart AI analysis method to an electrical-signal-based ultrasensitive biosensor.


This is another good signal of the emerging progress in understanding what plant-based psychogenics can contribute to helping humans heal and expand consciousness.
many researchers are excited. Several trials show dramatic results: in a study published in November 2020, for example, 71% of people who took psilocybin for major depressive disorder showed a greater than 50% reduction in symptoms after four weeks, and half of the participants entered remission. Some follow-up studies after therapy, although small, have shown lasting benefits

How ecstasy and psilocybin are shaking up psychiatry

Regulators will soon grapple with how to safely administer powerful psychedelics for treating depression and post-traumatic stress disorder.
Once dismissed as the dangerous dalliances of the counterculture, these drugs are gaining mainstream acceptance. Several states and cities in the United States are in the process of legalizing or decriminalizing psilocybin for therapeutic or recreational purposes. And respected institutions such as Imperial; Johns Hopkins University in Baltimore, Maryland; the University of California, Berkeley; and the Icahn School of Medicine at Mount Sinai in New York City have opened centres devoted to studying psychedelics. Several small studies suggest the drugs can be safely administered and might have benefits for people with intractable depression and other psychological problems, such as post-traumatic stress disorder (PTSD). One clinical trial involving MDMA has recently ended, with results expected to be published soon. Regulators will then be considering whether to make the treatment available with a prescription.

Psychedelic-assisted psychotherapy could provide needed options for debilitating mental-health disorders including PTSD, major depressive disorder, alcohol-use disorder, anorexia nervosa and more that kill thousands every year in the United States, and cost billions worldwide in lost productivity.

But the strategies represent a new frontier for regulators. “This is unexplored ground as far as a formally evaluated intervention for a psychiatric disorder,” says Walter Dunn, a psychiatrist at the University of California, Los Angeles, who sometimes advises the US Food and Drug Administration (FDA) on psychiatric drugs. Most drugs that treat depression and anxiety can be picked up at a neighbourhood pharmacy. These new approaches, by contrast, use a powerful substance in a therapeutic setting under the close watch of a trained psychotherapist, and regulators and treatment providers will need to grapple with how to implement that safely.

a 2014 Pew Research report found that 39 per cent of Americans believed that poverty was due to a lack of effort on poor people’s part. When ‘effort’ includes an inability to properly weigh up the risks inherent in a decision, this suggests that, in the end, many of us think that people are responsible for their own bad luck.

… insights from complexity science – specifically, computational complexity theory – show mathematically that there are hard limits on our capacity to make accurate and precise calculations of risk. Since it’s often impossible to get a reasonable sense of what will happen in the future, it’s unfair to blame people with good intentions who end up worse off as a result of unforeseen circumstances. This leads to the conclusion that compassion, not blame, is the appropriate attitude towards those who act in good faith but whose bets in life don’t pay off.

The starting point is to note that, for people to be held responsible for their actions, they have to know about certain features of the world. In many cases, even this minimal condition for blameworthiness isn’t satisfied. 

The bar for blameworthiness can be made more precise by saying that, in order to be blamed for a gamble, people must possess an accurate causal model of the system in which they act. That is, they must know how different variables in the system do or don’t affect one another.

 trying to infer the most likely causal structure of a system – no matter how much data we have about it – is what theorists call an NP-hard problem: given a general dataset, it can be fiendishly hard for an algorithm to learn the causal structure that produced it. In many cases, as more variables are added to the dataset, the minimum time that it takes any algorithm to learn the structure of the system under study grows exponentially. 

The mathematical case against blaming people for their misfortune




There’s a worry that the golden promise of cyberspace, that is, the happy Tomorrow of internet and AI—there’s a worry that it’s been coopted by the Pig, the Man, spyware, big biz, the data miners, and the spammers. One fears the frontier has been tamed and made ordinary. But that might not be true.

As a writer, your one power over the world is to depict realties that are in line with the way things should be. Or realities that reflect the way things really are. Even though these truer realties may not be widely recognized. I like to depict smart, empathetic characters doing wild and crazy things. There are plenty of people like this—I meet them all the time in my variously intersecting circles of mathematicians, writers, hackers, hipsters, computer people, and artists. But you don’t necessarily see these people in many of the books and movies and videos out there.

If you write about the world as you feel it should be, or like it secretly is, you encourage disaffected readers to hang in there, to stay strong, to be themselves, and keep on the path to the hoped-for Tomorrow.

For decades I read Scientific American to keep an eye on what’s new. But sadly they’ve turned to shit—small fonts and articles about—gak—sociology and political policy and economics? As if. Nowadays it’s enough to keep a loose eye on Twitter, and see the wonders trundling past—like a holiday parade that never ends. Grab hold of anything you see—and tweak it a little bit, and make it your own. Connect it in some way to your actual personal life—that’s the move I call transrealism. And go a little meta—that’s a trickier tactic I’m always trying to master—flip your idea up a level, and into something having to do with states of consciousness, or with the nature of language, or with the meaning of dreams. Go further out. There’s still so much. We’re just getting started.

Rudy Rucker - How to Be a Cult Underground Writer




The relation between appearance and reality is paramount to understanding Western art. When the mind had been separated from the world, art was then targeted to produce a world of images for private consumption by individual subjects. Science, art, and the layman live in the conceptual playground defined by the contrast between the mind and the world 

The mind represents the world. We experience our surroundings. We see the sky, smell flowers. We hear beautiful melodies. Nonetheless, as it has been observed countless times, if you peer inside the brain of someone who is watching a green field of grass, you are not going to find anything green. The brain is just a brain: gray, bloody, and in the dark. 

So, to make a long story short, a scientific explanation of consciousness is still missing. It is still largely a mystery that, although the brain lurks in the dark of our cranium, when we open our eyes, we see the bright light of the sun.

Is the Mind Like a Rainbow?





Another vital contribution of Peirce’s is his fallibilism, the idea that we cannot guarantee truth for any beliefs (though there is some dispute as to whether to extend this idea to mathematics and logic). Fallibilism is important because it means that no matter how much evidence we have collected, induction doesn’t guarantee that the next bit of data won’t show us to be mistaken. However, Peirce did not take this to mean that truth is never possible. For Peirce, enquiry is a community activity, and it is unbounded by time, in principle. Thus, truth is whatever the community of enquirers would agree to be the case by the end of enquiry – ie, by the end of time. This is not the same as denying the existence of Truth, but Peirce’s views require a certain humility and acceptance of the idea that all knowledge is subject to revision.

Nor must any synechist say: ‘I am altogether myself, and not at all you.’ If you embrace synechism, you must abjure this metaphysics of wickedness. In the first place, your neighbours are, in a measure, yourself, and in far greater measure than, without deep studies in psychology, you would believe. Really, the selfhood you like to attribute to yourself is, for the most part, the vulgarest delusion of vanity.

This is a sort of sad signal - about the challenge of not connecting the next billion people but the difficulty of connecting the last billion people to the Internet. 
We talk a lot about connecting the next billion users, but the reality is Loon has been chasing the hardest problem of all in connectivity—the last billion users: The communities in areas too difficult or remote to reach, or the areas where delivering service with existing technologies is just too expensive for everyday people. While we’ve found a number of willing partners along the way, we haven’t found a way to get the costs low enough to build a long-term, sustainable business. Developing radical new technology is inherently risky, but that doesn’t make breaking this news any easier. Today, I’m sad to share that Loon will be winding down.

Loon’s bubble bursts—Alphabet shuts down Internet balloon company

After eight years, Loon couldn't find a "long-term, sustainable business."
When Google announced "Project Loon" in 2013, a running joke behind the project was that no one thought a network of flying Internet balloons was a feasible idea. Eight years later, Google has decided that a network of flying Internet balloons is indeed not a feasible idea. Loon announced it is shutting down, citing the lack of a "long-term, sustainable business."

Google also cited economic problems when it shut down Titan Aerospace in 2017, a plan to deliver the Internet via drone.

The name "Loon" came partly from the fact that the project uses flying balloons as a kind of ultra-low-orbit satellite, but also from how "loony" the idea sounded to everyone outside the project. Google's introductory blog post explained the idea of a flying network of Internet balloons and followed up by saying, "The idea may sound a bit crazy—and that’s part of the reason we’re calling it Project Loon—but there’s solid science behind it."

The science mostly seemed to work out. Loon's sales pitch was that about half of the world was not on the Internet. The offline areas are too remote, without enough backhaul to build a traditional Internet infrastructure. So let's build everything here and fly it over there, and then everyone can use our flying Internet infrastructure in the sky. The Loon balloons were flying cell phone towers—they could deliver an LTE signal down to regular smartphones (the cheapest computers we have) with no special equipment for the end user. There was also a home version of Loon with a cute red balloon antenna. Google wanted to integrate Loon balloons into the traditional cell phone network and had partnerships with AT&T, Telkom Kenya, and Telefonica in Peru.


Stuart Kauffman is one of my intellectual heroes bring biological principles to challenge a predominant ‘physics worldview’ of change. This is a 8 page paper well worth the read.
mathematical systems shine as pure crystals and one might expect them to be consistent and complete, as indeed Hilbert did. These hopes have been destroyed by G¨odel, who has set the limits of deductive systems. Despite these limits, we currently rely on mathematical models for understanding systems of any sort, conscious of the possible incompleteness of the deductions we make. But there is a kind of incompleteness we have probably overlooked: what can be entailed by a formal system is already contained in it, and we cannot expect to be able to deduce novelty, to entail the becoming of the biosphere.

The world is not a theorem

Abstract 
The evolution of the biosphere unfolds as a luxuriant generative process of new living forms and functions. Organisms adapt to their environment, and exploit novel opportunities that are created in this continuous blooming dynamics. Affordances play a fundamental role in the evolution of the biosphere, as they represent the opportunities organisms may choose for achieving their goals, thus actualizing what is in potentia. In this paper we maintain that affordances elude a formalization in mathematical terms: we argue that it is not possible to apply set theory to affordances, therefore we cannot devise a mathematical theory of affordances and the evolution of the biosphere. 


A good article signaling the enrichment of our understanding of evolution.
Does the way in which animals improve environments in relation to their needs demand new ways of thinking about evolution’s adaptive landscape? From the most radical niche-construction standpoint, the answer is ‘yes’: organisms don’t just adapt, they co-direct evolution. 
as they move through evolutionary time, organisms don’t just suppress their fitness, but they can also improve their environment, and hence their fitness relative to it. This engineering is sufficiently powerful to help determine evolutionary outcomes.
niche construction modifies natural selection in an orderly, directed and sustained manner. It doesn’t just change, but directs adaptive evolution, by imposing a statistical bias on the direction and strength of selection.
Evolving populations are less like zombie mountaineers, and more like industrious landscape designers

Evolution’s engineers

Organisms do not evolve blindly under forces beyond their control, but shape and influence the evolutionary environment itself
the theory of niche construction is controversial among evolutionary biologists, partly because natural selection is traditionally believed to work ‘blindly’: it is thought to sculpt organisms over millennia to become adapted to their ecological niches, with no steer from the goals or purposes of organisms. Humans undergo the same sculpting, but rather than evolving to fit a pre-existing niche, it’s widely accepted that we’re active agents who shape the environments to which we adapt. Our brains have evolved to process linguistically encoded information and learned knowledge because we built a rich cultural realm and then adapted to it. We domesticated plants and animals and, by incorporating them into our diets, triggered selection for genes that metabolise these foods. We invented agriculture, which fuelled population growth, inadvertently selecting for genetic resistance to diseases of the crowd such as typhoid or cholera. Our parents don’t just transmit their genes to us; we also inherit the changed world they leave in their wake. This ecological inheritance means that humans don’t evolve in response to a static adaptive landscape, but instead mould that landscape to alleviate or intensify the particular selective pressures it places upon us. ‘[T]he organism influences its own evolution, by being both the object of natural selection and the creator of the conditions of that selection,’ as the evolutionary biologists Richard Levins and Richard Lewontin put it.

Just like humans, earthworms have constructed their own niche. Their environments aren’t fixed as rich or poor, but remain dynamic and changeable according to the activity of their inhabitants. Worms aren’t just altering soils – they’re cultivating crops, releasing greenhouse gasses, building homes and aggregating into cities that sprawl out into the countryside, just as we do.

Nor are earthworms the only species that improve their environment through niche construction: marine algae secrete sticky chemicals that bind the sand and stabilise the environment; chaparral and pine trees promote forest fires, which burn off the competition, through dispersing flammable needles, cones and oils; and ant species eliminate trees unsuitable for their colonies by spraying them with acid herbicides or cultivating fungus crops.


Here’s an interesting signal of both niche construction and harnessing natural compounds for human uses.
This discovery marked the first report of a specialized metabolite with broad geographic distribution produced by ant-associated bacteria. While this metabolite was safe for the fungal crop, it inhibited growth of fungal parasites, though—unlike many antibiotics—only in the absence of iron. It was also effective in fighting a Candida albicans infection in mice, comparable to azole-containing antifungal treatments that are used clinically, making it a potential drug candidate.

New antifungal compound from ant farms

Attine ants are farmers, and they grow fungus as food. Pseudonocardia and Streptomyces bacteria are their farmhands, producing metabolites that protect the crop from pathogens. Surprisingly, these metabolites lack common structural features across bacteria from different geographic locations, even though the ants share a common ancestor. Now, researchers report in ACS Central Science they have identified the first shared antifungal compound among many of these bacteria across Brazil. The compound could someday have medical applications.

Attine ants originated as one species at a single location in the Amazon 50 million years ago. They have evolved to 200 species that have spread their farming practices throughout South and Central America. In exchange for food, bacteria at these farms produce small molecules that hold pathogenic fungi such as Escovopsis in check. However, these molecules differ from region to region, suggesting a highly fragmented and geographically limited evolutionary history for the bacteria. Monica T. Pupo, Jon Clardy and colleagues wanted to find out if any antifungal bacterial metabolites with broader distribution had been overlooked in prior investigations.


The debate between nature and nurture has never been completely resolved - but now we also have nature and nature to account for difference in how DNA creates life.
Drawing on deCODE’s genetic databases to analyze variation in multiple cells sampled from 381 monozygotic twin pairs and their immediate family members, the researchers pinpointed a number of mutations that arose during this stage of development in just one member of each pair, meaning that at birth, so-called identical twins may already differ genetically from each other.

Identical Twins Accumulate Genetic Differences in the Womb

DNA replication errors during cell division cause monozygotic twins to diverge from each other even during the earliest stages of development, a new study finds.
Identical twins are not as identical as previously assumed, according to a study published in Nature Genetics. Rather than having exactly the same DNA sequences, twins start accumulating genetic variation from the earliest stages of development, researchers at Iceland-based company deCODE genetics found, meaning that one twin harbors variants that aren’t present in the other.

Also known as monozygotic twins because they develop from a single fertilized egg, identical twins have long been central to research on the relative effects of genes and environment—aka “nature versus nurture.” Although everyone accumulates some genetic mutations during their lifetime, the differences in identical twins were assumed to be minimal, particularly when twins are young, allowing researchers to study how different environments influence the development of people with the same genotype.

The new study focuses specifically on mutations that occur as or before embryos form from the mass of cells inside the blastocyst, a structure that implants in the uterine wall. During this stage of development, this inner cell mass can split to form two separately developing embryos.


And understanding evolution Darwinian selection has been challenged by horizontal gene transfer - of course as with many thing - the answer is not either-or - but AND.

Plant Cells Swap Organelles

Their relocation explains horizontal genome transfer first described more than a decade ago.
Past genetic experiments have shown that, when plants are grafted together, entire genomes can move between the host and the graft, but it was not clear how the genetic material was traveling. In a study published in Science Advances, researchers demonstrated that entire organelles can move between plant cells, bringing their genomes along for the ride.

In the studies before this one, “there was no way to rationally explain how a whole genome got over, other than it went into an organelle. Otherwise, you would have seen genetic recombination between an incoming genome and the resident genome,” says Pal Maliga, a plant biologist at Rutgers University who did not participate in the work. The nucleus, mitochondria, and plastids—the group of small organelles that includes chloroplasts—all contain genetic material. Researchers therefore made the inference that the genomes were moving via organelles, he explains, “but this paper is beautifully showing what the details are. I was very happy to see that the assumptions that were there to explain the biology are actually real.”

A team led by Ralph Bock of the Max Planck Institute of Molecular Plant Physiology showed in a study published in 2009 that grafted tobacco plants could share entire genomes. Horizontal gene transfer—when genetic material passes between individuals via some method other than fertilization—has been shown to influence plant evolution at various levels, including sharing of beneficial genes, but the movement of entire genomes is much less common and understood. While the initial and subsequent studies hinted that the transferred DNA was likely coming from the genomes contained in moving organelles, researchers couldn’t be sure that naked DNA wasn’t being shared in large chunks


This is a hopeful signal of one way to mitigate climate change and food shortages and reclaim our deserts. I remember talking about a possibility of something like this 10 years ago.

This is how you grow vegetables in the Sahara – by piping seawater from the Red Sea across the sands to produce biofuels and electricity.

The ambition of the Sahara Forest Project is to make the world’s deserts productive again, ultimately restoring vegetation. A team of engineers, architects, biologists, environmentalists and business people have come together to create a concept based on a simple, yet big, idea: Why not make use of proven environmental technologies and take what we have enough of – saltwater, sunlight and desert land – to produce what we need more of? That would be sustainable food, water and energy.

All they require is a low­-lying area of desert that is close to the ocean of which, like people, the earth has in abundance. 

Founded on the premise that we must find a more holistic approach to successfully tackle challenges related to energy, food and water security, the new Sahara Forest Project saltwater pipeline, scheduled to be finished late summer 2021, will carry water from the Red Sea – piping seawater to innovative bio­plants where clusters of solar and salt water evaporation technologies will combine to produce biofuels and electricity, as well as food crops and purified water. 

A few other projects are enacting other forms of greening.

The water allies hydrating Greek islands

In the Greek islands, a community of ‘water allies’ is working to solve the problems of water supply, wastewater and biodiversity loss – by extracting water from unconventional sources.

Clever cocoons transform the drylands

No irrigation? No problem. These clever tree-planting cocoons can bring soil back to life and restore dry, dusty land back to its former, greener glory.


And a similar signal in a different domain.

New eco-friendly way to make ammonia could be boon for agriculture, hydrogen economy

Ammonia has sustained humanity since the early 20th century, but its production leaves a huge carbon footprint. Now researchers have found a way to make it 100 percent renewable.
Chemical engineers at UNSW Sydney and University of Sydney have found a way to make 'green' ammonia from air, water and renewable electricity that does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound.

And the new production method—demonstrated in a laboratory-based proof of concept—also has the potential to play a role in the global transition towards a hydrogen economy, where ammonia is increasingly seen as a solution to the problem of storing and transporting hydrogen energy.

In a paper published today in Energy and Environmental Science, the authors from UNSW and University of Sydney say that ammonia synthesis was one of the critical achievements of the 20th century. When used in fertilizers that quadrupled the output of food crops, it enabled agriculture to sustain an ever-expanding global population.


Hydrogen has been a signal for a renewable energy source for decades now - perhaps we will see it sooner then the horizon of skepticism predicts - but then there are still ‘details’ to deal with.

World-first home hydrogen battery stores 3x the energy of a Powerwall 2

To get off the grid with home solar, you need to be able to generate energy when the Sun's out, and store it for when it's not. Normally, people do this with lithium battery systems – Tesla's Powerwall 2 is an example. But Australian company Lavo has built a rather spunky (if chunky) cabinet that can sit on the side of your house and store your excess energy as hydrogen.

The Lavo Green Energy Storage System measures 1,680 x 1,240 x 400 mm (66 x 49 x 15.7 inches) and weighs a meaty 324 kg (714 lb), making it very unlikely to be pocketed by a thief. You connect it to your solar inverter (it has to be a hybrid one) and the mains water (through a purification unit), and sit back as it uses excess energy to electrolyze the water, releasing oxygen and storing the hydrogen in a patented metal hydride "sponge" at a pressure of 30 bar, or 435 psi.

It stores some 40 kilowatt-hours worth of energy, three times as much as Tesla's current Powerwall 2 and enough to run an average home for two days. And when that energy is needed, it uses a fuel cell to deliver energy into the home, adding a small 5-kWh lithium buffer battery for instantaneous response. There's Wi-Fi connectivity, and a phone app for monitoring and control, and businesses with higher power needs can run several in parallel to form an "intelligent virtual power plant."


Shades of science fiction - anyone who enjoyed the 2004-9 version of ‘Battlestar Galactica’ may have also loved the spin-off prequel of 20910 called Caprica - if anyone watched this series - then this may send some shivers up your spine. Also more recently:
 It is famously the plot of the Black Mirror episode “Be Right Back”, where a young woman uses a service to scrape data from her deceased partner to create a chatbot – and eventually a robot.

MICROSOFT PATENT SHOWS PLANS TO REVIVE DEAD LOVED ONES AS CHATBOTS

Microsoft has been granted a patent that would allow the company to make a chatbot using the personal information of deceased people.  
The patent describes creating a bot based on the “images, voice data, social media posts, electronic messages”, and more personal information.

“The specific person [who the chat bot represents] may correspond to a past or present entity (or a version thereof), such as a friend, a relative, an acquaintance, a celebrity, a fictional character, a historical figure, a random entity etc”, it goes on to say.

“The specific person may also correspond to oneself (e.g., the user creating/training the chat bot,” Microsoft also describes – implying that living users could train a digital replacement in the event of their death.

Microsoft has even included the notion of 2D or 3D models of specific people being generated via images and depth information, or video data.
