Friday Thinking 23 July, 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.

The claim that capitalism is being toppled by a new economic model comes on the heels of many premature forecasts of capitalism’s demise, especially from the left. But this time it may well be true, and the signs that it is have been visible for a while.

This is how capitalism ends: not with a revolutionary bang, but with an evolutionary whimper. Just as it displaced feudalism gradually, surreptitiously, until one day the bulk of human relations were market-based and feudalism was swept away, so capitalism today is being toppled by a new economic mode: techno-feudalism.

Perhaps the clearest sign that something serious is afoot appeared on August 12 last year. On that day, we learned that, in the first seven months of 2020, the United Kingdom’s national income had tanked by over 20%, well above even the direst predictions. A few minutes later, the London Stock Exchange jumped by more than 2%. Nothing comparable had ever occurred. Finance had become fully decoupled from the real economy.

after 2008, everything changed. Ever since the G7’s central banks coalesced in April 2009 to use their money printing capacity to re-float global finance, a deep discontinuity emerged. Today, the global economy is powered by the constant generation of central bank money, not by private profit. Meanwhile, value extraction has increasingly shifted away from markets and onto digital platforms, like Facebook and Amazon, which no longer operate like oligopolistic firms, but rather like private fiefdoms or estates.

That central banks’ balance sheets, not profits, power the economic system explains what happened on August 12, 2020. Upon hearing the grim news, financiers thought: “Great! The Bank of England, panicking, will print even more pounds and channel them to us. Time to buy shares!” All over the West, central banks print money that financiers lend to corporations, which then use it to buy back their shares (whose prices have decoupled from profits). Meanwhile, digital platforms have replaced markets as the locus of private wealth extraction. For the first time in history, almost everyone produces for free the capital stock of large corporations. That is what it means to upload stuff on Facebook or move around while linked to Google Maps.

Techno-Feudalism Is Taking Over




Modernist architecture and town planning bolstered this new obsession, doing away with what architects saw as dark, filthy, disease-infested city centres to replace them with open squares and light-infused, gleaming white buildings both public and private. The 19th-century’s dust-filled carpets, heavy curtains and intricately carved furniture were ousted from interiors to be replaced with low-maintenance, easy-clean linoleum and furniture that was functional and sculptural.

By the early 1920s, the visual and written language of architecture was directly reflecting current medical practice. Without antibiotics, and with viruses barely understood, the millions of tuberculosis and influenza sufferers could only pin their hopes on the contemporary belief that exposure to sunlight and fresh air would save them. Pure white, light-reflecting, visibly sterile walls, sun-drenched balconies, big windows and sleeping porches replaced the dingy closed wards of the Victorian infirmaries; even their name, ‘sanatoriums’, held promise of health and recuperation. Their design features were echoed in domestic dwellings and holiday resorts.

The sink in the hall: how pandemics transform architecture




the brain may be more like a musical instrument. When you play the piano, how often you hit the keys matters, but the precise timing of the notes is also essential to the melody.

Neurons Unexpectedly Encode Information in the Timing of Their Firing





In his magnum opus Being and Time (1927), Martin Heidegger used the notion of ‘projection’ (Entwurf) to describe the two dimensions to self-confidence we distinguished in patients receiving DBS. In ordinary German usage, the noun Entwurf and the verb entwerfen refer to the sketching of some project to be carried out (for instance, an architect drawing a new building in a sketchbook). Heidegger points out that projection is not a matter of thinking up and carrying out a plan. Instead, it refers to the freedom a person has to press forward into a range of possibilities; it means taking a stand on who we are. With Entwurf, Heidegger hoped to capture a forward momentum to the living of life.

Human beings can seize hold of possibilities and embark on projects that shape their self-understanding – the person’s understanding of who they are. For Heidegger, a person’s self-understanding of who they are comes from an openness to the world and its possibilities. 

World wide open




Unfortunately, Bayesian theory and its statistical underpinnings also fall into the same trap of truth via authority. Certainly, humans perform hypothesis generation and empirical testing, but to label this and the scientific method Bayesian borders on the absurd. Because Bayesianism adopts methods we’ve created to predict games of chance and made it gospel. The bait in the scientific method is essential, the switch is that Bayesian theory depicts the scientific method therefore Bayesian method must be valuable.

Unfortunately, Bayesian theory is the flat earth theory of the scientific method. As an analogy, AI believed that formulating programs that played chess would lead to AI. But like games of chance, games of chess are closed problems. Reality in contrast is open-ended.

The scientific method works because there are many minds that criticize the hypotheses that are made. A key cognitive bias of humans is that we are very poor at criticizing our own thoughts. We are however very good at criticizing other thoughts. The scientific method works because it is a collective method. It took 9,700 generations to accept it because you needed to convince a majority in society to shun the hierarchical structure of civilization and to embrace an alternative.

To convince all of humanity requires scalable technology. That was writing and scaled further with the invention of the printing press. The scientific method would not be so prevalent without a mechanism for the distribution of information.

One cannot formulate intelligence that is in vats. That is because intelligence requires learning and learning demands engagement with an environment that can change independently of the mind that interacts with it. Therefore, if we are to reverse engineer minds, we have to understand environments that lead to learning and not to stagnation.

Collective deliberative thinking is an innate capability in humans. However, hierarchical organizations were invented to effectively coordinate civilizations at scale.

The scientific method is a civilization-scale learning method that rests on decentralized criticisms of existing practices.

Goodhart’s law reminds us that the hierarchical structure that we invented to scale civilization for our benefit will be reimagined to protect the hierarchy and not the living beings in the hierarchy.

No truth is without some mixture of error, and no error so false but that it possesses no element of truth. If a man is in too big a hurry to give up an error, he is liable to give up some truth with it, and in accepting the arguments of the other man he is sure to get some errors with it. Honest argument is merely a process of mutually picking the beams and motes out of each other’s eyes so both can see clearly…

reason didn’t evolve to help individuals reach truths, but to facilitate group communication and co­operation. Reasoning makes us smarter only when we practise it with other people in argument.

A good scrap





This is a great signal of a turn in Tech policy thinking and implementation. We must all understand this concept to better shape the future of our - of-by-for Internet.
interoperability can enhance privacy by giving users more choice and making it easier to switch away from services that are built on surveillance.

The New ACCESS Act Is a Good Start. Here’s How to Make Sure It Delivers.

The ACCESS Act is one of the most exciting pieces of federal tech legislation this session. Today’s tech giants grew by taking advantage of the openness of the early Internet, but have designed their own platforms to be increasingly inhospitable for both user freedom and competition. The ACCESS Act would force these platforms to start to open up, breaking down the high walls they use to lock users in and keep competitors down. It would advance the goals of competition and interoperability, which will make the internet a more diverse, more user-friendly place to be.

We’ve praised the ACCESS Act as “a step towards a more interoperable future.” However, the bill currently before Congress is just a first step, and it’s far from perfect. While we strongly agree with the authors’ intent, some important changes would make sure that the ACCESS Act delivers on its promise.


One of the inevitables is the digital city - the smart city. The question is - Are we going to let tech companies colonize our digital future the way we are letting urban, for-profit developers colonize the architecture of our future cities? The focus on renewing our infrastructure should include a fiber-optic strategy for every home and business as part of our public infrastructure - to prevent a future where for-profit rent-seeking corporations determine what is possible. 
in Kolkata, India, a startup has provided postal addresses to more than 120,000 slum residents using geocoding technology, helping them obtain documentation to access government services, open bank accounts, and register to vote.
Smart city initiatives that shift from being technology-centric to citizen-centric put engagement and inclusion at the center. Using this framework, cities have more tools to engage diverse stakeholders in solution creation and share the benefits of smart cities—quality of life, economic growth, and sustainability—with all residents. Six enablers work around these core principles to bring smart cities to life: data and security, digital and technology, ecosystem, finance and funding, internal organization, and policy and regulation.

Inclusive smart cities

Delivering digital solutions for all
​As inclusion becomes integral to urban centers, how can it be extended to smart city programs? And how can technology better enable inclusion across city services, public engagement, and economic opportunities?

Moving from technology-centric to citizen-centric smart cities
AS urban populations grow increasingly diverse, many cities are turning to technology and smart city solutions to build more livable environments and improve the delivery of public services.1 These initiatives have the potential to expand access to city services, improve public engagement, and spur economic growth. However, smart city design and implementation shortcomings, coupled with the digital divide between different population segments, might unintentionally leave some communities behind. This is forcing cities to confront the question: How can digital solutions advance, rather than impede, inclusion?

This article explores the relationship between technological innovation and inclusion in today’s cities. Based on research, interviews, and engagement with city leaders around the world, we outline approaches that municipal governments can apply to make digital solutions more accessible and useful for their residents.


This is a good signal of two things the continued emergence of the quantified self - and the willingness of the MAGA-F (Microsoft, Apple, Google, Amazon, Facebook, et al) companies to use everything about our lives to make themselves more money.

Amazon Gets the Go-Ahead to Track Your Sleep With Radar

As you might expect, it's all about piling on more ads.
 On Friday, the Federal Communications Commission gave the e-commerce giant clearance to create bedside radar devices meant to track how we toss and turn at night. And while Amazon’s putting the best face possible on the innovation, it’s still all about those ad dollars.

Bloomberg was first to notice the agency had quietly filed a memo that authorized the ecommerce giant to develop and deploy an “unlicensed radar device” meant to track any nearby movement. This was in response to an initial request that Amazon filed with the agency nearly three weeks ago, where the company described its vision for “Radar Sensors”. These devices, Amazon said, would fire high-frequency radio waves to map out movements from anyone nearby.

And because the FCC is the federal body responsible for policing the airwaves, Amazon was legally obligated to get their go-ahead before they began marketing this yet-to-be-licensed radar device.


When considering complex and living systems in the light of sensitivity to initial conditions - we can’t know how small a difference will make a difference (and if it does we won’t know when and what difference it will make). Nor do we know how big a difference will be that makes no difference. 

Only a tiny fraction of our DNA is uniquely human

The result underscores how big of a hand interbreeding among ancient hominids had in shaping us
Only 1.5 percent to 7 percent of the collective human genetic instruction book, or genome, contains uniquely human DNA, researchers report July 16 in Science Advances.

That humans-only DNA, scattered throughout the genome, tends to contain genes involved in brain development and function, hinting that brain evolution was important in making humans human. But the researchers don’t yet know exactly what the genes do and how the exclusively human tweaks to DNA near those genes may have affected brain evolution.

“I don’t know if we’ll ever be able to say what makes us uniquely human,” says Emilia Huerta-Sanchez, a population geneticist at Brown University in Providence, R.I., who was not involved in the study. “We don’t know whether that makes us think in a specific way or have specific behaviors.” And Neandertals and Denisovans, both extinct human cousins, may have thought much like humans do.


Everything that can be automated will be - and now the protein folding game played by thousands of humans called FoldIt may face a different future.

DeepMind’s AI for protein structure is coming to the masses

Machine-learning systems from the company and from a rival academic group are now open source and freely accessible.
It’s protein-structure prediction for the people. Software that accurately determines the 3D shape of proteins is set to become widely available to scientists.

On 15 July, the London-based company DeepMind released an open-source version of its deep-learning neural network AlphaFold 2 and described its approach in a paper in Nature. The network dominated a protein-structure prediction competition last year.

Meanwhile, an academic team has developed its own protein-prediction tool inspired by AlphaFold 2, which is already gaining popularity with scientists. That system, called RoseTTaFold, performs nearly as well as AlphaFold 2, and is described in a Science paper also published on 15 July.

The open-source nature of the tools means that the scientific community should be able to build on the advances to create even more powerful and useful software, says Jinbo Xu, a computational biologist at the University of Chicago in Illinois, who was not involved in either effort.


Covid has accelerated some aspects of medical treatment - new forms of vaccine and treatment - perhaps this is a next phase.

‘Super-antibodies’ could curb COVID-19 and help avert future pandemics

Companies are designing next-generation antibodies modeled on those taken from unique individuals whose immune systems can neutralize any COVID-19 variant—and related coronaviruses, too.
The US Food and Drug Administration (FDA) granted Emergency Use Authorization (EUA) in late May to sotrovimab, providing a new therapeutic weapon in the fight against SARS-CoV-2—and future coronaviruses with pandemic potential.

According to analysts and researchers alike, so-called super-antibodies such as sotrovimab should have an edge over first-generation monoclonal antibody (mAb) therapies for COVID-19 because of their broad neutralization capacity in the face of emerging virus variants. “Physicians aren’t going to sequence what version of the virus people have, so they’ll go for the antibodies that have the higher barrier to resistance or the ones that work on [known] variants,” says Phil Nadeau, an analyst at Cowen.

The antibody therapy from Vir Biotechnology and GlaxoSmithKline, a recombinant human immunoglobulin G1 mAb, is now the third mAb-based treatment marketed for individuals with mild-to-moderate COVID-19 who are at high risk for progression to severe disease. (Eli Lilly and Regeneron each have a two-mAb cocktail with EUAs for the same indication.) And although sales opportunities should diminish for all these products as vaccination rates increase worldwide, Nadeau anticipates there will be a sustained market for COVID-19 mAbs to help treat individuals who, for medical reasons, can’t mount an appropriate immune response to vaccination or, for whatever reason, elect not to get the shot.


This is a very exciting signal of the progress being made in understanding cancer.

New research finds common denominator linking all cancers

All cancers fall into just two categories, according to new research from scientists at Sinai Health, in findings that could provide a new strategy for treating the most aggressive and untreatable forms of the disease.

In new research out this month in Cancer Cell, scientists at the Lunenfeld-Tanenbaum Research Institute (LTRI), part of Sinai Health, divide all cancers into two groups, based on the presence or absence of a protein called the Yes-associated protein, or YAP.

Rod Bremner, senior scientist at the LTRI, said they have determined that all cancers are present with YAP either on or off, and each classification exhibits different drug sensitivities or resistance. YAP plays an important role in the formation of malignant tumours because it is an important regulator and effector of the Hippo signaling pathway.

"Not only is YAP either off or on, but it has opposite pro- or anti-cancer effects in either context," Bremner said. "Thus, YAPon cancers need YAP to grow and survive. In contrast, YAPoff cancers stop growing when we switch on YAP."


Another small signal of progress in quantum computing.

Chinese achieve new milestone with 56 qubit computer

A team of researchers affiliated with multiple institutions in China, working at the University of Science and Technology of China, has achieved another milestone in the development of a usable quantum computer. The group has written a paper describing its latest efforts and have uploaded it to the arXiv preprint server.

Back in 2019, a team at Google announced that they had achieved "quantum supremacy" with their Sycamore machine—a 54 qubit processor that carried out a calculation that would have taken a traditional computer approximately 10,000 years to complete. But that achievement was soon surpassed by other teams from Honeywell and a team in China. The team in China used a different technique, one that involved the use of photonic qubits—but it was also a one-trick pony. In this new effort, the new team in China, which has been led by Jian-Wei Pan, who also led the prior team at the University of Science and Technology has achieved another milestone.


This is an interesting signal of a plant recently legalized. :)
Cannabis has been used for millennia for textiles and for its medicinal and recreational properties.
The evolution of the cannabis genome suggests the plant was cultivated for multipurpose use over several millennia.

Cannabis first domesticated 12,000 years ago: study

Cannabis was first domesticated around 12,000 years ago in China, researchers found, after analyzing the genomes of plants from across the world.

The study, published in the journal Science Advances on Friday, said the genomic history of cannabis domestication had been under-studied compared to other crop species, largely due to legal restrictions.

The researchers compiled 110 whole genomes covering the full spectrum of wild-growing feral plants, landraces, historical cultivars, and modern hybrids of plants used for hemp and drug purposes.

The study said it identified "the time and origin of domestication, post-domestication divergence patterns and present-day genetic diversity".

It’s becoming clear that ecosystems and organisms rely on viruses. Tiny but mighty, they have fuelled evolution for millions of years by shuttling genes between hosts. In the oceans, they slice open microorganisms, spilling their contents into the sea and flooding the food web with nutrients. “Without viruses,” says Curtis Suttle, a virologist at the University of British Columbia in Vancouver, Canada, “we would not be alive.”

There are minuscule circoviruses with only two or three genes, and massive mimiviruses that are bigger than some bacteria and carry hundreds of genes. There are lunar-lander-looking phage that infect bacteria and, of course, the killer spiky balls the world is now painfully familiar with. There are viruses that store their genes as DNA, and others that use RNA; there’s even a phage that uses an alternative genetic alphabet, replacing the chemical base A in the standard ACGT system with a different molecule, designated Z.

...many scientists’ suspicion that there’s no one common ancestor for virus-kind. “There is no single root for all viruses,” says Koonin. “It simply does not exist.” That means that viruses probably arose several times in the history of life on Earth — and there’s no reason to think such emergence can’t happen again. “The de novo origin of new viruses, it’s still ongoing,” says Mart Krupovic, a virologist at the Pasteur Institute in Paris who was involved in both the ICTV decisions and Koonin’s taxonomy team.

Viruses can also influence other organisms by stirring up their genomes. For example, when viruses transfer antibiotic-resistance genes from one bacterium to another, drug-resistant strains can take over. Over time, this kind of transfer can create major evolutionary shifts in a population, says Camarillo-Guerrero. And not just in bacteria — an estimated 8% of human DNA is of viral origin. For example, our mammalian ancestors acquired a gene essential for placental development from a virus.

Beyond coronavirus: the virus discoveries transforming biology





Anil Seth enumerates five different kinds of self-models: bodily, perspectival, volitional, narrative and social selves. These selves are not orthogonal and perhaps partially ordered in what is a prerequisite over another. In his essay “The Real Problem”:

There is the bodily self, which is the experience of being a body and of having a particular body. There is the perspectival self, which is the experience of perceiving the world from a particular first-person point of view. The volitional self involves experiences of intention and of agency — of urges to do this or that, and of being the causes of things that happen. At higher levels, we encounter narrative and social selves.

all the world models involve the inclusion of self-models. These self-modes are all ‘Inside Out’ architectures. To understand compositionality, an agent needs an intuitive understanding of the body. To predict physics requires an intuitive awareness of where and what direction one is looking at when one makes an observation. To understand how to learn, one needs to know how to interact with the world.. To understand causality, one needs the capability of following stories. To understand psychology, one needs an understanding of oneself. In summary, you cannot develop any of the skills that Brendan Lake describes without a previous grounding with a model of the self. Self-models are a necessary requirement for the stepping stones of AGI [Artificial General Intelligence].

I find it more informative to frame consciousness in terms of self-models. The reason for this is that living things are primarily driven by homeostasis. Antonio Damasio in “The Strange Order of Things” argues that the brain’s function at its core is driven by homeostasis. Damasio writes:

Feelings are the mental expressions of homeostasis, acting under the cover of feeling, is the functional thread that links early life-forms to the extraordinary partnership of bodies and nervous systems.

It ensures that life is regulated within a range that is not just compatible with survival but also conducive to flourishing.

Homeostasis and a Definition of Intelligence





To understand physics you need to invent a lot of new languages (see: calculus for Newton). It should be no surprise that understanding cognition requires the invention of a new language.

The problem with our natural language is that it is noun-centric. Unfortunately, all of reality is process-centric. Thus, when we stick exclusively to a noun-centric language, we cannot properly map the complexity of reality.

The Mass Appeal of Reductionist Metaphors





It is a truism of technological progress that whatever can be automated will be - of course there will always be lots of work to do and activity to engage in. But this is a great signal for how things that we didn’t imagine being automated can be.

AI Designs Quantum Physics Experiments Beyond What Any Human Has Conceived

Originally built to speed up calculations, a machine-learning system is now making shocking progress at the frontiers of experimental quantum physics
Quantum physicist Mario Krenn remembers sitting in a café in Vienna in early 2016, poring over computer printouts, trying to make sense of what MELVIN had found. MELVIN was a machine-learning algorithm Krenn had built, a kind of artificial intelligence. Its job was to mix and match the building blocks of standard quantum experiments and find solutions to new problems. And it did find many interesting ones. But there was one that made no sense.

“The first thing I thought was, ‘My program has a bug, because the solution cannot exist,’” Krenn says. MELVIN had seemingly solved the problem of creating highly complex entangled states involving multiple photons. Krenn, Anton Zeilinger of the University of Vienna and their colleagues had not explicitly provided MELVIN the rules needed to generate such complex states, yet it had found a way. Eventually, he realized that the algorithm had rediscovered a type of experimental arrangement that had been devised in the early 1990s. But those experiments had been much simpler. MELVIN had cracked a far more complex puzzle.

Their latest effort, an AI called THESEUS, has upped the ante: it is orders of magnitude faster than MELVIN, and humans can readily parse its output. While it would take Krenn and his colleagues days or even weeks to understand MELVIN’s meanderings, they can almost immediately figure out what THESEUS is saying.


A fascinating signal for how affordances can enable something very useful from innovation aimed at imaginary possibilities.

How Hans Berger’s quest for telepathy spurred modern brain science

Instead of finding long-range signals, he invented EEG

A brush with death led Hans Berger to invent a machine that could eavesdrop on the brain.

In 1893, when he was 19, Berger fell off his horse during maneuvers training with the German military and was nearly trampled. On that same day, his sister, far away, got a bad feeling about Hans. She talked her father into sending a telegram asking if everything was all right.

To young Berger, this eerie timing was no coincidence: It was a case of “spontaneous telepathy,” he later wrote. Hans was convinced that he had transmitted his thoughts of mortal fear to his sister — somehow.

So he decided to study psychiatry, beginning a quest to uncover how thoughts could travel between people. Chasing after a scientific basis for telepathy was a dead end, of course. But in the attempt, Berger ended up making a key contribution to modern medicine and science: He invented the electroencephalogram, or EEG, a device that could read the brain’s electrical activity.

Berger’s machine, first used successfully in 1924, produced a readout of squiggles that represented the electricity created by collections of firing nerve cells in the brain.


This is a signal of the emerging understanding that life itself has been playing around with DNA.
“Here was this wonderful validation that right under our noses, nature has been expanding,”
“It really speaks to the adaptability of the genetic alphabet,”
Z and other modified DNA bases seem to have evolved to help viruses evade the defenses with which bacteria degrade foreign genetic material. 

DNA Has Four Bases. Some Viruses Swap in a Fifth.

The DNA of some viruses doesn’t use the same four nucleotide bases found in all other life. New work shows how this exception is possible and hints that it could be more common than we think.
All life on Earth rests on the same foundation: a four-letter genetic alphabet spelling out a repertoire of three-letter words that specify 20 amino acids. These basic building blocks — the components of DNA and their molecular interpreters — lie at biology’s core. “It’s hard to imagine something more fundamental,” said Floyd Romesberg, a synthetic biologist at the pharmaceutical company Sanofi.

Yet life’s foundational biochemistry can be full of surprises. A few decades ago, researchers found viruses that had swapped one of the four bases in their DNA for a novel fifth one. Now, in a trio of papers published in Science in April, three teams have identified dozens of other viruses that make this substitution, as well as the mechanisms that make it possible. The discoveries raise the thought-provoking possibility that this kind of fundamental genomic change could be much more widespread and important in biology than anyone imagined.

The scientists have now reported finding the Z substitution in more than 200 phages. Further analysis of the viral genomes allowed the research groups to uncover a key enzyme for making Z, as well as an enzyme that degrades free-floating A nucleotides, making Z more likely to be taken up during DNA synthesis.


There was a significant debate during the early years of the theory of Evolution between Darwin and Lamark concerning whether acquired characteristic (e.g. big muscles) could be passed from acquiring parent to children - in recent decades we’ve learned about the working of epigenetics. This is an interesting signal about our progress in understanding epigenetics.
In the new study, Jose and his team found while breeding nematode worms that some matings led to epigenetic changes in offspring that continued to be passed down through as many generations as the scientists continued to breed them. This discovery will enable scientists to explore how epigenetic changes are passed to future generations and what characteristics make genes susceptible to permanent epigenetic changes.

Match matters: The right combination of parents can turn a gene off indefinitely

Evidence suggests that what happens in one generation—diet, toxin exposure, trauma, fear—can have lasting effects on future generations. Scientists believe these effects result from epigenetic changes that occur in response to the environment and turn genes on or off without altering the genome or DNA sequence.

But how these changes are passed down through generations has not been understood, in part, because scientists have not had a simple way to study the phenomenon. A new study by researchers at the University of Maryland provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal's biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations. The research was published on July 9, 2021, in the journal Nature Communications.

"There's a lot of interest in heritable epigenetics," said Antony Jose, associate professor of cell biology and molecular genetics at UMD and senior author of the study. "But getting clear answers is difficult. For instance, if I'm on some diet today, how does that affect my children and grandchildren and so on? No one knows, because so many different variables are involved. But we've found this very simple method, through mating, to turn off a single gene for multiple generations. And that gives us a huge opportunity to study how these stable epigenetic changes occur."


Who knows when quantum computing will emerge as a viable alternate computational paradigm? This is a small signal of progress.
 it is the combination of system's unprecedented size and programmability that puts it at the cutting edge of the race for a quantum computer, which harnesses the mysterious properties of matter at extremely small scales to greatly advance processing power.
"The number of quantum states that are possible with only 256 qubits exceeds the number of atoms in the solar system,"

Team develops quantum simulator with 256 qubits, largest of its kind ever created

A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum simulator capable of operating with 256 quantum bits, or "qubits."

The system marks a major step toward building large-scale quantum machines that could be used to shed light on a host of complex quantum processes and eventually help bring about real-world breakthroughs in material science, communication technologies, finance, and many other fields, overcoming research hurdles that are beyond the capabilities of even the fastest supercomputers today. Qubits are the fundamental building blocks on which quantum computers run and the source of their massive processing power.

"This moves the field into a new domain where no one has ever been to thus far," said Mikhail Lukin, the George Vasmer Leverett Professor of Physics, co-director of the Harvard Quantum Initiative, and one of the senior authors of the study published today in the journal Nature. "We are entering a completely new part of the quantum world."


A good small signal of new agricultural processes that are more ecological.

New production method makes vital fertilizer element in a more sustainable way

Urea is a critical element found in everything from fertilizers to skin care products. Large-scale production of urea, which is naturally a product of human urine, is a massive undertaking, making up about 2% of global energy use and emissions today.

For decades, scientists and engineers have sought to make this process more energy efficient as demand for fertilizer grows with increased population. An international research team that includes scientists and engineers from The University of Texas at Austin has devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.

Making urea today involves a two-step thermal process that requires high levels of heat and pressure under controlled harsh environments. But this new process requires just one step and relies on a concept called electrocatalysis that uses electricity—and potentially sunlight—to trigger chemical reactions in a solution at room temperature in ambient conditions.

"Around the world we need to lower emissions. That's why we want to develop these more sustainable pathways to produce urea using electrocatalysis instead of this energy-intensive two-step process," said Guihua Yu, an associate professor of materials science in the Cockrell School of Engineering's Walker Department of Mechanical Engineering who co-led the team that published a new milestone paper about the process in Nature Sustainability.


It seems like a couple of decades have passed since the ‘hydrogen economy’ was a salient buzz in the news. But significant progress towards the use of hydrogen for renewable energy and maybe especially energy storage has continued.

World's biggest green hydrogen hub announced for Western Australia

Western Australia could soon be home to the world's biggest green hydrogen project. The Western Green Energy Hub (WGEH) wants to deploy 50 GW of solar and wind generation to produce up to 3.5 million tons of green hydrogen or 20 million tons of ammonia a year.

This monster project edges out the 45-GW Svevind project in Kazakhstan that was announced just a couple of weeks ago. It underscores the huge paydays the energy industry is foreseeing in green energy exports.

Yes, hydrogen is inefficient and borderline wasteful compared to storing and releasing green energy in batteries. But the world is aiming to decarbonize completely by 2050, and batteries simply don't have the energy density for many applications, such as long-haul trucking, shipping and aviation. Hydrogen will also be key in decarbonizing steel production – and it represents and energy export opportunity in a post-coal and oil world that doesn't look like it's getting a global energy grid any time soon to share renewable power without putting it on boats.

The new hub would take advantage of Western Australia's excellent solar potential and solid wind potential, occupying some 15,000 square kilometers (5,800 sq mi) of largely red, rocky desert near Kalgoorlie in the south-east of the state. Construction would be in phases, to ramp up as expected demand for these green fuels grows.


Not to be outdone but here’s what a small, very advanced country is up to.

Singapore unveils one of world's biggest floating solar farms

Singapore Wednesday unveiled one of the world's biggest floating solar power farms, covering an area the size of 45 football pitches, as part of the city-state's push to cut greenhouse gas emissions.

The project is the country's most ambitious yet, comprising 122,000 panels on Tengeh Reservoir that will produce enough electricity to run its five water treatment plants.

Singapore is among the biggest per capita carbon dioxide emitters in Asia and its land scarcity makes boosting renewable energy sources a challenge.

The prosperous financial hub has turned to setting up plants off its coasts and in reservoirs, and aims to quadruple solar energy production by 2025.

The new farm can produce up to 60 megawatts of electricity, and will lead to carbon emissions reductions equivalent to removing 7,000 cars from roads, according to Sembcorp Industries and national water agency PUB.


A weak signal - that any and every technology can be weaponized. This has glimpses of quite a few speculative fiction scenarios - but this intended use is pretty cool too - what could go wrong?

Swarm of autonomous tiny drones can localize gas leaks

When there is a gas leak in a large building or at an industrial site, human firefighters currently need to go in with gas sensing instruments. Finding the gas leak may take considerable time, while they are risking their lives. Researchers from TU Delft (the Netherlands), University of Barcelona, and Harvard University have now developed the first swarm of tiny—and hence very safe—drones that can autonomously detect and localize gas sources in cluttered indoor environments.

The main challenge the researchers needed to solve was to design the Artificial Intelligence for this complex task that would fit in the tight computational and memory constraints of the tiny drones. They solved this challenge by means of bio-inspired navigation and search strategies. The scientific article has now been made public on the ArXiv article server, and it will be presented at the renowned IROS robotics conference later this year. The work forms an important step in the intelligence of small robots and will allow finding gas leaks more efficiently and without the risk of human lives in real-world environments.
