Friday Thinking 17 July 2020

Friday Thinking is a humble curation of my foraging in the digital environment. My purpose is to pick interesting pieces, based on my own curiosity (and the curiosity of the many interesting people I follow), about developments in some key domains (work, organization, social-economy, intelligence, domestication of DNA, energy, etc.)  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 will SKILL the cat.

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

Increased correlation length is a hallmark of phase transitions, in which particles transition from a disordered to an ordered arrangement or vice versa. It happens, for instance, when atoms in a block of iron collectively align so that the block becomes magnetized. As the block approaches this transition, each atom influences atoms farther and farther away in the block.

Why Is Glass Rigid? Signs of Its Secret Structure Emerge





One standard response is simply to go with available scientific evidence and to just listen to the experts. That’s what I call the technocratic approach – quantitative information is the guiding light, and anxieties or concerns of the public are dismissed as irrelevant. At the other end of the spectrum is what I call the populist approach, where the will of the public is taken as the ultimate verdict on policy. Even though the public might be emotional – and hence supposedly irrational – public opinion should still be the guide, either for democratic objectives or for pragmatic, instrumental ones.


…. both approaches are misguided for the same reason: they don’t take emotions and underlying values seriously. Obviously, it’s crucial to uncover the relevant scientific facts to make important decisions about, say, risky technologies and pandemics. But such decisions aren’t just a matter of gathering scientific information and listening to experts, as important as that is. Scientific information is necessary, but it’s not sufficient. We also have to take into account societal and ethical considerations, and that requires explicit ethical reflection, which in turn requires attention for emotions.


Many researchers from psychology and philosophy, such as Nico Frijda, Antonio Damasio and Martha Nussbaum, have shown that our emotions help us with so-called ‘practical rationality’ – that is, making decisions in complex real-life situations. In my own work, I argue that emotions are important for having moral insights. Emotions are not by definition at odds with rationality, but can be an important source of moral reflection. They point to what matters to us morally. Emotions can draw attention to important ethical considerations that frequently get overlooked in quantitative, science-based approaches to risk.


Of course, emotions can also be misguided, but the same holds for all sources of insight. Emotions need to be critically assessed based on scientific information and rational analysis, as well as by emotional reflection and deliberation.


Emotionally charged human capacities such as imagination can play an important role in developing and thinking about future scenarios. The prospect of catastrophic climate change requires us to envisage different ways of life, and different scenarios for how to run a more sustainable economy, with more durable energy sources and lower consumption. Artists, filmmakers and writers can play an important role in making these scenarios vivid. Art appeals to the imagination; it can make abstract problems more concrete, and so facilitate ethical deliberation on the implications of such future scenarios.

Emotions should be in the heart of complex political debates





Here is one more important signal of the emergence of a new economic paradigm and social platform for flourishing in the 21st century. In the times of Covid - we’ve redefined what work is essential - and it’s not in the executive suite.

“If there’s ever an opportunity to try to push for some sort of income floor that can be paid out in cash to people, this is the time to do it,” says Damon Jones, an economist at the University of Chicago in Illinois.

Pandemic speeds largest test yet of universal basic income

Economists welcome the chance to see whether giving people cash to spend however they choose improves livelihoods.

Spain’s government has started what might just be remembered as the world’s biggest economics experiment. On 15 June, spurred by the coronavirus crisis and its economic fallout, it launched a website offering monthly payments of up to €1,015 (US$1,145) to the nation’s poorest families.


The programme, which will support 850,000 households, is the largest test yet of an idea called universal basic income (UBI) — in which people are given a cash payment each month to spend however they choose. It has been oft-discussed but never satisfactorily tested, and economists around the world are watching closely to see what the impact of the scheme on livelihoods will be.


The move comes at a time of unprecedented economic turmoil brought on by the coronavirus pandemic. Spain was one of the hardest-hit countries in the early days of the pandemic. The nationwide lockdown curbed the spread of the virus, but came at a staggering financial price. Millions of people lost their jobs as the economy shrank rapidly, putting many of the most vulnerable citizens at risk.



As the saying goes - never let a serious crisis go to waste - Covid-19 has revealed the power of the sovereign nations to shape the political economy - in fact it is revealing that markets (where ever real markets exist) are a commons that must be governed by governments and nations. Along with Modern Monetary Theory - this economist argues for a profound re-thinking of the role of government in co-creating our economies.

The COVID-19 crisis is a chance to do capitalism differently

In the face of three simultaneous crises -- health, the economy and climate -- do we have a chance to do capitalism differently? Economist Mariana Mazzucato explains why we shouldn't try to go back to normal after the pandemic but should instead rethink how governments work together with businesses to solve big problems. Learn more about how governments can play a dynamic, proactive role in shaping markets and sparking innovation -- instead of just responding to broken systems. (This virtual conversation, hosted by TED Global curator Bruno Giussani, was recorded June 22, 2020.)



This is an interesting signal - of the emergence of plant medicines as important therapeutic tools - perhaps better than the current pharmacopeia of patented profit makers.

“We are thrilled that Oregon voters have come together to tackle mental health and depression by qualifying this ballot measure for the November election,” says Tom Eckert, co-chief petitioner on the initiative. “Oregonians deserve access to psilocybin therapy as a treatment option – and now we officially have a chance to win it.”

Oregon to officially vote on legalizing psychedelic psilocybin therapy

The state of Oregon will officially vote on legalizing psilocybin psychotherapy in the upcoming November election, after well over 150,000 signatures were collected to secure the landmark ballot measure. The initiative focuses on licensed and regulated psychedelic-assisted psychotherapy in clinical environments.


After more than a year of work, and significant pandemic disruptions, the Oregon Psilocybin Society has successfully collected the signatures necessary for IP-34, an initiative legalizing psilocybin psychotherapy, to be on the statewide ballot in the November 2020 election.


IP-34 is solely focused on legalizing psilocybin within a clinical and therapeutic context. Unlike other, more broad, calls for legalization or decriminalization, this ballot measure does not allow for recreational uses of psilocybin, or home cultivation. Instead, it lays out a two-year timeline for the planning and development of licensing and regulatory processes for establishing clinical spaces to administer psilocybin psychotherapy.



Any one who has engaged in even an attempt to meditate is immediately confronted with what has been called the ‘monkey mind’ as awareness dawns of just how difficult it is to train attention. This is an fascinating signal of science progress in the nature of the mind.

Discovery of 'thought worms' opens window to the mind

Queen's University researchers uncover brain-based marker of new thoughts and discover we have more than 6,000 thoughts each day.

Researchers at Queen's University have established a method that, for the first time, can detect indirectly when one thought ends and another begins. Dr. Jordan Poppenk (Psychology) and his master's student, Julie Tseng, devised a way to isolate "thought worms," consisting of consecutive moments when a person is focused on the same idea. This research was recently published in Nature Communications.


"What we call thought worms are adjacent points in a simplified representation of activity patterns in the brain. The brain occupies a different point in this 'state space' at every moment. When a person moves onto a new thought, they create a new thought worm that we can detect with our methods," explains Dr. Poppenk, who is the Canada Research Chair in Cognitive Neuroscience. "We also noticed that thought worms emerge right as new events do when people are watching movies. Drilling into this helped us validate the idea that the appearance of a new thought worm corresponds to a thought transition."


"Thought transitions have been elusive throughout the history of research on thought, which has often relied on volunteers describing their own thoughts, a method that can be notoriously unreliable," Dr. Poppenk adds. "Being able to measure the onset of new thoughts gives us a way to peek into the 'black box' of the resting mind—to explore the timing and pace of thoughts when a person is just daydreaming about dinner and otherwise keeping to themselves."



This is a good signal of the emergence of a range of ‘carbon capture’ methods - that will have to accompany all other carbon reduction initiatives.

preliminary results suggest the theory is holding up. The application of 20 tonnes of basalt dust to a half-hectare UK plot boosted CO2 removal by 40% compared with that seen on an untreated plot, and by 15% in another trial, which spread dust over oil-palm plantations in Malaysia. The early results also indicate that adding basalt boosted yields in these and other crops.

Pulling carbon from the sky is necessary but not sufficient

Carbon dioxide removal is becoming a serious proposition. But it is not a substitute for aggressive action to cut emissions.

Could spreading basalt dust on farmers’ fields help to remove atmospheric carbon? A large multidisciplinary team of scientists is confident it could, and that doing so could boost crop yields and soil health at the same time.


In this issue, David Beerling, a biogeochemist at the University of Sheffield, UK, and his colleagues explore a strategy to enhance rock weathering (D. J. Beerling et al. Nature 583, 242–248; 2020).


This is a continuously occurring natural phenomenon in which carbon dioxide and water react with silicate rocks on Earth’s surface. In the process, atmospheric CO2 is converted into stable bicarbonates that dissolve and then flow into rivers and oceans. The idea of scaling up this process to remove carbon has been considered for some three decades. The team’s results provide the most detailed analysis yet of the technical and economic potential of this approach — and some of the probable challenges, including gaining public acceptance.


The researchers modelled what would happen to atmospheric carbon if basalt dust was added to agricultural lands in the world’s biggest economies, including Brazil, China, the European Union, India, Indonesia and the United States. According to their calculations, doing so would remove between 0.5 billion and 2 billion tonnes of CO2 from the air each year. The upper limit is more than 5 times the annual emissions of the United Kingdom, and akin to offsetting emissions from around 500 coal-fired power plants.



A good signal of the emergence of new agricultural paradigm - rather than the 100 kilometer diet - think about the 10 mile diet. 

Vertical farming is a type of indoor agriculture where crops are cultivated in stacked systems with water, lighting and nutrient sources carefully controlled.

It is part of a rapidly growing sector supported by artificial intelligence in which machines are taught to manage day to day horticultural tasks. The industry is set to grow annually by 21% by 2025 according to one commercial forecast (Grand View Research, 2019).

Space to grow, or grow in space—how vertical farms could be ready to take-off

Vertical farms with their soil-free, computer-controlled environments may sound like sci-fi. But there is a growing environmental and economic case for them, according to new research laying out radical ways of putting food on our plates.

The interdisciplinary study combining biology and engineering sets down steps towards accelerating the growth of this branch of precision agriculture, including the use of aeroponics which uses nutrient-enriched aerosols in place of soil.


Carried out by the John Innes Centre, the University of Bristol and the aeroponic technology provider LettUs Grow, the study identifies future research areas needed to accelerate the sustainable growth of vertical farming using aeroponic systems.


Dr. Antony Dodd, a group leader at the John Innes Centre and senior author of the study, says: "By bringing fundamental biological insights into the context of the physics of growing plants in an aerosol, we can help the vertical farming business become more productive more quickly, while producing healthier food with less environmental impact."



Another signal of the progress towards the domestication of DNA - and the metabolic factories we call living systems. 

Scientists make precise gene edits to mitochondrial DNA for first time

Weird enzyme enables researchers to study — and potentially treat — deadly diseases.

A peculiar bacterial enzyme has allowed researchers to achieve what even the popular CRISPR–Cas9 genome-editing system couldn’t manage: targeted changes to the genomes of mitochondria, cells’ crucial energy-producing structures.


The technique — which builds on a super-precise version of gene editing called base editing — could allow researchers to develop new ways to study, and perhaps even treat, diseases caused by mutations in the mitochondrial genome. Such disorders are most often passed down maternally, and impair the cell’s ability to generate energy. Although there are only a small number of genes in the mitochondrial genome compared with the nuclear genome, these mutations can particularly harm the nervous system and muscles, including the heart, and can be fatal to people who inherit them.


But it has been difficult to study such disorders, because scientists lacked a way to make animal models with the same changes to the mitochondrial genome. The latest technique marks the first time that researchers have made such targeted changes, and could allow researchers to do this. “It’s a very exciting development,” says Carlos Moraes, a mitochondrial geneticist at the University of Miami in Florida. “The ability to modify mitochondrial DNA would allow us to ask questions that, before, we could not.” The work was published on 8 July in Nature.



This is a weak signal of a healthier longer lived life - through of the domestication of DNA and so much more.

Boosting a liver protein may mimic the brain benefits of exercise

Liver-made proteins that circulate in the blood improved memories, a mouse study suggests

A chemical signal from the liver, triggered by exercise, helps elderly mice keep their brains sharp, suggests a study published in the July 10 Science. Understanding this liver-to-brain signal may help scientists develop a drug that benefits the brain the way exercise does.


Lots of studies have shown that exercise helps the brain, buffering the memory declines that come with old age, for instance. Scientists have long sought an “exercise pill” that could be useful for elderly people too frail to work out or for whom exercise is otherwise risky. “Can we somehow get people who can’t exercise to have the same benefits?” asks Saul Villeda, a neuroscientist at the University of California, San Francisco.


The researchers closely studied one of these liver proteins produced in response to exercise, called GPLD1. GPLD1 is an enzyme, a type of molecular scissors. It snips other proteins off the outsides of cells, releasing those proteins to go do other jobs. Targeting these biological jobs with a molecule that behaves like GPLD1 might be a way to mimic the brain benefits of exercise, the researchers suspect.


Old mice that were genetically engineered to make more GPLD1 in their livers performed better on the memory tasks than other old sedentary mice, the researchers found. The genetically engineered sedentary mice did about as well in the pool of water as the mice that exercised. “Getting the liver to produce this one enzyme can actually recapitulate all these beneficial effects we see in the brain with exercise,” Villeda says. 



Just how complex are ecological links, connections and media of communication? This is a good signal related to how information may just be a defining and ubiquitous feature of life.

Detection of electrical signaling between tomato plants raises interesting questions

The soil beneath our feet is alive with electrical signals being sent from one plant to another, according to research in which a University of Alabama in Huntsville (UAH) distinguished professor emeritus in the Department of Electrical and Computer Engineering participated.


UAH's Dr. Yuri Shtessel and Dr. Alexander Volkov, a professor of biochemistry at Oakwood University, coauthored a paper that used physical experiments and mathematical modeling to study transmission of electrical signals between tomato plants.


when the plants are living in common soil, experiments conducted by Dr. Volkov found that the ground impedance is not very large and they can communicate by passing electrical signals to each other through the Mycorrhizal network in the soil.



This is a very disturbing but important signal - for many reasons - demonstrating the entanglement of human ailments with the human condition and most disturbing the still widespread incidence of sexual and violent abuse.

Researchers find link between rape and long-term breathing problems

Rape and sexual trauma may have long-lasting consequences for physical health as well as mental health, University of Otago researchers have found.

The team of researchers, led by respiratory specialist Professor Bob Hancox and sexual health specialist Dr. Jane Morgan from Waikato DHB, found a history of rape is associated with "dysfunctional breathing" in both women and men, and with late-onset asthma diagnosis in women.


"Dysfunctional breathing," which is also known as hyperventilation syndrome, involves breathing too deeply or too rapidly. People can present with chest pain and a tingling sensation in the fingertips and around the mouth and it may accompany a panic attack.


While previous studies have found that a history of adverse events and psychological trauma, including sexual trauma, are associated with self-reported asthma, links with other respiratory problems have not been examined. Professor Hancox explains the team set out to assess whether the experience of being raped—an extreme form of psychological trauma—was associated with dysfunctional breathing among participants in the Dunedin Multidisciplinary Health and Development Study.


This world-renowned study is a longitudinal investigation of health and behaviour in a group of 1037 people born in Dunedin in 1972 or 1973 and followed regularly throughout their lives.

Nearly 20 percent of women and 4 percent of men in the study reported being raped at some stage throughout their life. Both men and women who had reported being raped were more likely to have dysfunctional breathing at 38 years of age.



This 13 minute video provides a great comprehensive description of a renewable energy storage system.

Liquid Air Batteries. Literally energy from thin air. Seriously. Literally!

Energy storage from thin air sounds a bit too good to be true, but the beauty of this potentially transformational technology is the simplicity of a design that utilises tried and tested components that have been reimagined and re-engineered to perform a vital function for electricity grids, now and in the future.  



Here is a good signal that we are still some distance away from self-driving vehicles.

German court rules Tesla's 'Autopilot' is false advertising

A German court ruled Tuesday that specific terms used by Tesla for its electric cars' assistance features are false advertising, including the vehicles' "Autopilot" feature.


Judges at the higher state court in Munich found use of the term "Autopilot" as well offering as the option to buy a Model 3 vehicle with "full potential for autonomous driving" were "misleading business acts".


"Use of the relevant terms creates an expectation... that does not correspond to the actual facts," the court said in a statement.


Tesla's "Autopilot" does not enable a trip without any human intervention at all, the judges found.

Neither would such a technology be legal under present German law, they added.

Friday Thinking 10 July 2020

Friday Thinking is a humble curation of my foraging in the digital environment. My purpose is to pick interesting pieces, based on my own curiosity (and the curiosity of the many interesting people I follow), about developments in some key domains (work, organization, social-economy, intelligence, domestication of DNA, energy, etc.)  that suggest we are in the midst of a change in the conditions of change - a phase-transition.

Woody Harrelson - Triple 9




the Big Tech platforms have pursued growth through classic monopoly tactics: buying their nascent competitors, merging with their biggest rivals, cornering entire vertical markets.

They cheated.


To see how this plays out in the real world, consider Facebook: it’s a company that has hostages, not users. In 2018, Facebook was rocked by the largest exodus of US customers in the company’s history: 15 million 13-34 year olds left Facebook. See, the market works!


Not so fast.

The vast majority of those users who left Facebook ended up on Instagram, which has been a Facebook division since 2012, when Zuckerberg and co paid $1 billion to acquire the company, explicitly to capture younger users who were abandoning Facebook.

Cory Doctorow: Inaction is a Form of Action




it’s an important reminder of what we often forget: scientists are human beings, and are subject to very human flaws. Most notably, they’re subject to bias, and a strong aversion to having their cherished theories proved wrong. The fact that Ioannidis, the world’s most famous sceptic of science, is himself subject to this bias is the strongest possible confirmation of its psychological power. The Eysenck and Ioannidis stories differ in very many ways, but they both tell us how contrarianism and iconoclasm — both crucial forces for the process of constant scepticism that science needs to progress — can go too far, leading researchers not to back down, but to double-down in the face of valid criticism.


Above, I should really have said that John Ioannidis was a hero of mine. Because this whole episode has reminded me that those self-critical, self-correcting principles of science simply don’t allow for hero-worship. Even the strongest critics of science need themselves to be criticised; those who raise the biggest questions about the way we do research need themselves to be questioned. Healthy science needs a whole community of sceptics, all constantly arguing with one another — and it helps if they’re willing to admit their own mistakes. Who watches the watchmen in science? The answer is, or at least should be: all of us.

There should never be heroes in science




Most of the criticism that I’ve received has come from those who are deeply invested in media literacy who were frustrated with my depiction of the field. I respect that I’m challenging a sacred cow, although I reject the criticism that I’m dismissing the values, goals, or ideals that are central to those who are working hard to find a way to education the next generation. I also stand by my finding that there are a lot of things that currently exist in everyday classrooms that are labeled “media literacy.” One if the weirdest parts of doing fieldwork across the country sampling for diverse communities and youth is that I’ve seen a lot of dynamics in schools that are unimaginable to my friends in education. I’ve seen kids smoking marijuana in class while the substitute teacher of the day desperately tries to gain control. I’ve walked in on kids having sex in the teacher’s lounge; they weren’t ashamed but mostly annoyed that I interrupted. I’ve watched a biology teacher integrate creationism into his lessons. And yes over and over and over again, I’ve heard teachers tell students not to use Wikipedia. Sadly, this isn’t an outdated finding. I truly wish it were. I also wish that I didn’t watch parents tell their kids that only Fox was a trustworthy news source. Or the inverse. This is part of the reality of this country, whether we like it or not. And I’m trying to grapple with the array of dynamics that happen in the over 125,000 schools in this country. Part of what is challenging about talking in an environment like SXSW-Edu is that it’s comprised of a self-selected group of educators.


Another critique that I’ve received stems from a misreading of my argument. I am not arguing that media literacy causes hatred. I’m arguing that it doesn’t solve it. And, more importantly, that a well-intended but ineffective intervention can actually do harm. I grew up with Nancy Reagan’s War on Drugs campaign, the one the involved the frying pan and the egg. When my peers started experimenting with marijuana and concluded that it was nothing like the message they heard, they assumed that there was no truth to the message that drugs mess with your brain. Coke and then meth flew through my community. I’ve long been angered by how these unnuanced messages failed to engage people with where they were. As a result, I want us to be cautious as we’re entering into a conversation about media literacy solutionism. Do we really know what the outcomes will be? Or do we just hope that it will be what we intend it to be? Facebook intended to create community. Netflix intended to inform people about the costs of bullying.


where we are in society isn’t just a product of any one vector. It’s an ecosystem. We could talk about how climate is destabilizing migration patterns, which is magnifying fear of other. We could talk about how the rise in perceived inequality is rooted in the debt culture and the implications this has for radicalizeable young people. We could talk about how the loss of news media is rooted in private equity and how not knowing anyone in the industry undermines trust in the journalistic project. There are many factors at play. But my goal with this talk wasn’t to talk about root causes; it was to challenge a common solution being put forward based on what I’m already seeing play out.


What surprised me the most is how few folks really grappled with my primary argument: if we’re not careful, media literacy and critical thinking will be deployed as an assertion of authority over epistemology.


For what it’s worth, when I try to untangle the threads to actually address the so-called “fake news” problem, I always end in two places: 1) dismantle financialized capitalism (which is also the root cause of some of the most challenging dynamics of tech companies); 2) reknit the social fabric of society by strategically connecting people. But neither of those are recommendations for educators.

A Few Responses to Criticism of My SXSW-Edu Keynote on Media Literacy





This is a good signal of the emergence of automated transportation.

Networks of self-driving trucks are becoming a reality in the US

The self-driving truck company TuSimple is laying the groundwork for a futuristic autonomous freight industry.

Fully autonomous trucking may be one step closer to reality. On Wednesday, the San Diego-based self-driving startup TuSimple announced what it’s calling the world’s first autonomous freight network. That means that the company is laying the groundwork for delivering a lot more of our stuff with self-driving trucks.


TuSimple is hardly the only company working to making fully automated shipping a reality. Several companies, including Aurora, Daimler, and Embark Trucks, are competing for a slice of the future of self-driving freight trucks. Alphabet-owned Waymo confirmed on Tuesday that it will be expanding its own self-driving trucking routes throughout the American Southwest and Texas, following previous tests in Arizona, California, Michigan, and Georgia.


TuSimple’s expansion plans seem more concrete than some of its competitors. The company is expanding existing shipments with UPS, which has also invested in TuSimple, and the foodservice delivery giant McLane. The major shipping company US Xpress, one of the nation’s largest freight companies, will also start shipping goods through TuSimple, which now has 22 contracted customers. Those companies will ultimately have influence over which routes are digitally mapped out next for self-driving trucks.



This is a very interesting signal of the emergence of the post-human - new ways to restore lost sensory capacity and potentially enhance it.

Nanotechnology applied to medicine: The first liquid retina prosthesis

Research at IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) has led to the revolutionary development of an artificial liquid retinal prosthesis to counteract the effects of diseases such as retinitis pigmentosa and age-related macular degeneration that cause the progressive degeneration of photoreceptors of the retina, resulting in blindness. The study has been published in Nature Nanotechnology.


The study represents the state of the art in retinal prosthetics and is an evolution of the planar artificial retinal model developed by the same team in 2017 and based on organic semiconductor materials (Nature Materials 2017, 16: 681-689).


The 'second generation' artificial retina is biomimetic, offers high spatial resolution and consists of an aqueous component in which photoactive polymeric nanoparticles (whose size is 350 nanometres, thus about 1/100 of the diameter of a hair) are suspended, and will replace damaged photoreceptors.


The experimental results show that the natural light stimulation of nanoparticles, in fact, causes the activation of retinal neurons spared from degeneration, thus mimicking the functioning of photoreceptors in healthy subjects.



This is a great signal of the progress being made in autonomous flight - think flocks of drones. The 2 min video is spectacular.

German firm creates bionic birds

the latest creation from German robotics company Festo promises not only literal flights of fancy, but quite promising real-world applications down the road as well.

The company unveiled a video of a stunningly lifelike fleet of robo-birds that glide through the air with guidance from an ultra-sideband radio system.


Each of the five swallows weighs 42 grams. They each are powered by three tiny motors for direction, lift and descent. Their wingspan extends to 26 inches.


"The intelligent interaction of motors and mechanics allows the frequency of the wing beat and the elevator's angle of attack to be precisely adjusted for the various maneuvers," according to a report on the BionicSwift on Festo's web site.


The birds carry a 6 gram battery and they are guided by GPS sensors located throughout the enclosed flying area. The birds follow a preprogrammed flight path, but if an unexpected factor arises, such as a gust of air, radio communication enables instantaneous flight rerouting.



Another of the ever stronger signals of the emergence of a transformation of our energy paradigm.

"A faster transition from coal to clean energy is within our grasp, and we show how to engineer that transition in ways that will save money for electricity customers around the world while aiding a just transition for workers and communities," 

Coal reaching 'tipping point' vs renewables: analysis

Renewable energy such as wind and solar projects are already cheaper to build than it is to continue operating 40 percent of the world's existing coal fleet, according to analysis released Tuesday.


In a report outlining how the world can phase out the most polluting fuel while powering an economic recovery from the coronavirus pandemic, a group of experts said coal had reached a financial "tipping point" making it uncompetitive in most markets.


The authors estimate that a third of the global coal fleet is already more costly to run than it is to build new renewable power solutions, including battery storage.

That figure is set to rise to 73 percent of the fleet by 2025, said the analysis, which also found that replacing the entire coal fleet with clean energy could be done at a net saving to the global economy as soon as 2022.



This is definitely a strong signal of the effect of humans on Climate.

Major new paleoclimatology study shows global warming has upended 6,500 years of cooling

Comprehensive compilation of pre-historic temperature records shows that global warming is reaching levels not seen for at least 6,000 years

Over the past 150 years, global warming has more than undone the global cooling that occurred over the past six millennia, according to a major study published June 30 in Nature Research's Scientific Data, "Holocene global mean surface temperature, a multi-method reconstruction approach." The findings show that the millennial-scale global cooling began approximately 6,500 years ago when the long-term average global temperature topped out at around 0.7°C warmer than the mid-19th century. Since then, accelerating greenhouse gas emissions have contributed to global average temperatures that are now surpassing 1°C above the mid-19th century.


Earlier this year, an international group of 93 paleoclimate scientists from 23 countries -- also led by Kaufman, McKay, Routson and Erb -- published the most comprehensive set of paleoclimate data ever compiled for the past 12,000 years, compressing 1,319 data records based on samples taken from 679 sites globally. At each site, researchers analyzed ecological, geochemical and biophysical evidence from both marine and terrestrial archives, such as lake deposits, marine sediments, peat and glacier ice, to infer past temperature changes. Countless scientists working around the world over many decades conducted the basic research contributing to the global database.


"The rate of cooling that followed the peak warmth was subtle, only around 0.1°C per 1,000 years. This cooling seems to be driven by slow cycles in the Earth's orbit, which reduced the amount of summer sunlight in the Northern Hemisphere, culminating in the 'Little Ice Age' of recent centuries," said Erb, who analyzed the temperature reconstructions.


Since the mid-19th century, global warming has climbed to about 1°C, suggesting that the global average temperature of the last decade (2010-2019) was warmer than anytime during the present post-glacial period.



As a fan of zombie apocalypse movies (I think I’ve seen about 80% of every zombie movie ever made) - I had to share this.

Researchers find fans of apocalyptic movies may be coping with pandemic better

A small team of researchers from the University of Chicago, Pennsylvania State University, and Aarhus University has found that people who are exposed to end-of-the-world movies may be more resilient when dealing with the real-life ongoing pandemic. They have written a paper describing questioning volunteers about movies they had seen and their real pandemic experiences. Their paper is available on the PsyArXiv preprint server.


The researchers found that people who had recently watched what they describe as "prepper" movies showed signs of higher levels of resilience to the real-world pandemic. They suggest exposure to certain scenes in a movie psychologically prepared viewers for some of the events that unfolded as the real pandemic got underway. They further note that people watching generic horror movies also reported higher levels of coping abilities during the early days of the real pandemic. The researchers suggest such movies allow viewers to practice coping skills, which they apparently put to use if a real need arises.



I prefer to use the term ‘physical distancing’ rather than ‘social distancing’ - because to enact the physical distancing necessary to meet the challenge of this pandemic (and perhaps those in the future) we need strong, flexible, ever present social fabric that is all inclusive - we must pull together more (as a society and as social beings) in order to make physical distancing effective.

Animals Use Social Distancing to Avoid Disease

Lobsters, birds and some primates use quarantine to ward off infections

Despite how unnatural social distancing may feel to people, it is very much a part of the natural world, practiced by mammals, fishes, insects and birds.

Social animals stay apart, changing behaviors such as grooming to stop the spread of diseases that could kill them.

Strategies vary from shunning a sick animal to maintaining interactions with only the closest relatives.


On a shallow reef in the Florida Keys, a young Caribbean spiny lobster returns from a night of foraging for tasty mollusks and enters its narrow den. Lobsters usually share these rocky crevices, and tonight a new one has wandered in. Something about the newcomer is not right, though. Chemicals in its urine smell different. These substances are produced when a lobster is infected with a contagious virus called Panulirus argus virus 1, and the healthy returning lobster seems alarmed. As hard as it is to find a den like this one, protected from predators, the young animal backs out, into open waters and away from the deadly virus.


The lobster’s response to disease—seen in both field and laboratory experiments—is one we have become all too familiar with this year: social distancing. People’s close interactions with family and friends have been cut off to reduce the spread of COVID-19. It has been extremely hard. And many have questioned the necessity. Yet despite how unnatural it may feel to us, social distancing is very much a part of the natural world. In addition to lobsters, animals as diverse as monkeys, fishes, insects and birds detect and distance themselves from sick members of their species.


Immunity through behavior does come with costs, though. Social distancing from other members of your species, even temporarily, means missing out on the numerous benefits that favored social living in the first place. For this reason, researchers have learned that complete shunning is just one approach animals take. Some social species stay together when members are infected but change certain grooming interactions, for example, whereas others, such as ants, limit encounters between individuals that play particular roles in the colony, all to lower the risk of infection.



This may be a weak signal of another ‘demic’ of some sort or of some sort of complication arising from our current pandemic.

‘Unknown pneumonia’ deadlier than coronavirus sweeping Kazakhstan, Chinese embassy warns

Statement from embassy warns that death rate is ‘much higher’ than coronavirus and says local authorities have yet to identify cause

Kazakh authorities have reimposed Covid-19 lockdown in some parts of the country amid a spike in pneumonia cases last month


The country as a whole saw 1,772 pneumonia deaths in the first part of the year, 628 of which happened in June, including some Chinese nationals, the embassy continued.


Late last month officials warned about the rise in pneumonia cases. Kisikova said that doctors were finding 600 people a day with pneumonia symptoms, compared with 80 a day before the start of the Covid-19 outbreak, the Singapore-based website CNA reported.

“Every day, 350 to 400 patients are hospitalised in the city with either Covid-19 or pneumonia,”

We love nature - 

the nature we experience in our domesticated parks and gardens - 

until the noxious plant-bug-animal strikes us - 

poison ivy really sucks

Our itches - 

make us move - 

make us enact our response-ability - 

even when it’s irresponsible
