Friday Thinking 23 Oct 2020

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.

even from a predictive processing perspective, staying locally within the bounds of the expected is only one part of a much more complex story. For those very same predictive brains were designed to drive mobile, inquisitive creatures like ourselves. Such creatures must productively surf the waves of their own uncertainty. To do so, they probe and sample the world in ways that aim to reveal just where the key uncertainties lie, so that by future actions they can resolve them and move on. They seek new information, and they engage in complex rituals such as art and science whose role (we’ll argue) is in part at least to safely reveal and stress-test their own deepest assumptions.

Creatures like us, it seems, have added some brand-new layers to our relationship with the space of our own predictions, errors and uncertainties, turning that space into a kind of concrete arena that affords deeper and more challenging explorations than those undertaken by most other living organisms. We have discovered ways of turning our own best models (including our self-model) into objects apt for explicit questioning.

The examined human life reflects, we suggest, a new kind of relationship with our own expectations and uncertainty. Yet it is one that we have somehow constructed within the inviolable bounds of a biologically bedrock drive to minimise long-term prediction error. How is this neat trick possible?

Unexpected uncertainty arises when – for example – an environmental change causes us to become uncertain about our own generative model. Volatility is subtly different: it names a situation in which the frequency of changes in the environmental contingencies are themselves rapidly changing. Volatility is thus the most potentially anxiety-provoking species of uncertainty. It is uncertainty about the space of uncertainty itself.

When confronted with unexpected uncertainty, our brain reacts by increasing its learning rate

The many ways that we can fall prey to our own predictive brains correspond to the various ways in which we can become trapped by our own estimations of the reliability of different predictions. 

The value of uncertainty




Perhaps the most extraordinary transformation took place in Japan. The rebuilding of the Japanese economy after the war, under the direct control of the occupying US forces, involved a dramatic redistribution of wealth and influence away from ruling elites, in particular landowners and the bureaucratic and military elites responsible for Japanese expansionism. The US occupiers, under the unlikely direction of General Douglas MacArthur, levied eye-watering taxes such as 70 per cent on the largest fortunes, and expropriated absentee landlords. The biggest family-owned industrial conglomerates were dismantled and senior management fired. Meanwhile, the war more or less wiped out wealth held in stocks and corporate shares. Labour reforms boosted union membership leading to higher wages and enhanced job security. The purpose behind these reforms was clear: to uproot the concentration of wealth and power around a reactionary elite…

Democratic capitalism redressed the balance between the brutal inequalities of early industrial capitalism and the need for social consent to secure political stability. It rested on three broad pillars: a redistributive welfare state that provided economic security while narrowing income gaps between rich and poor, corporatist dialogue between employers and the labour force, and highly regulated capital markets. Aspects of this form of capitalism sometimes existed in nondemocratic societies too. But as a basic set of socioeconomic institutions it was most associated with the democratic form of government in which competitive elections and representative political parties incorporated citizen demands into policymaking. 

The increased role for government in distributing the fruits of economic growth meant that inequality and poverty fell to unprecedented levels. Taxes became far more progressive. In the 1950s, top marginal rates of income tax exceeded 90 per cent in Italy, the UK and the US. Unemployment benefits, pensions and family allowances expanded to provide secure incomes to households all across the income distribution. By taxing the rich and transferring money to the poor and middle-income groups, welfare states substantially reduced material hardship and ensured economic gains reached the least fortunate. The government also became a major employer, offering well-paid jobs with good working conditions and pension rights in the public administration and services such as the police, healthcare and education. All these measures meant that growth in living standards was spread across income groups.

Thirty glorious years




The phrase comes from the English critic Raymond Williams. I think his point was that we have basic biological feelings just as animals, that are the same for all of us at all times, but in any given moment, for any individual, we interpret these basic animal feelings by way of language—we give the feelings names, and these come from a particular language and a culture too, and so they are different in different times and places and languages, and the differences can be seen later on as being quite significant. So each culture and moment has its own particular structure of feeling, based on their language and what’s happening in the world at that time.

 no one can predict the future that will really come to pass, so don’t even try to do that.  

Think of your postulated futures as hopes and fears, typically, with your hopes being utopian, your fears dystopian. Go ahead and imagine a lot of them, and see how you feel about them, and what you think is realistic in them, in terms of suggesting things you can do now to make a better future for yourself and everyone else.  


Don’t get too impressed by any one technology or ideology—we all suffer from a bit of monocausotaxophilia, the love of single causes that explain everything, but reality isn’t really like that, so you have to take a lot of factors into account, and realize they will mix in unexpected ways in your head as in the world.  

Kim Stanley Robinson on inventing plausible utopias






The Covid-Apocalypse has revealed a lot about many of the myths underlying the neoliberal economic paradigm - this is another strong signal about the inevitable requirement of - Universal Basic Income. The 7 min video is well worth the view.

Opposition to a Universal Basic Income lies in how we think about the relationship between work and one's right to live.

Study after study seems to show us that direct cash transfers do indeed work. The problem lies in convincing people that they are deserving of the money.
We’ve had numerous trials of direct cash transfers. At this point, we know that people constantly use the money for what they need. Even more so do we know that they benefit not only recipients but local communities as a whole.

Still, we face resistance in actually implementing them. That lies far more in existing stereotypical beliefs of how we perceive the relationship between work and life.

Yes, more and more young adults are living with their parents – but is that necessarily bad?

When the Pew Research Center recently reported that the proportion of 18-to-29-year-old Americans who live with their parents has increased during the COVID-19 pandemic, perhaps you saw some of the breathless headlines hyping how it’s higher than at any time since the Great Depression.

From my perspective, the real story here is less alarming than you might think. And it’s actually quite a bit more interesting than the sound bite summary.

Yes, a lot of emerging adults are now living with their parents. But this is part of a larger, longer trend, with the percentage going up only modestly since COVID-19 hit. Furthermore, having grown kids still at home is not likely to do you, or them, any permanent harm. In fact, until very recently, it’s been the way adults have typically lived throughout history. Even now, it’s a common practice in most of the world.

Drawing on the federal government’s monthly Current Population Survey, the Pew Report showed that 52% of 18-to-29-year-olds are currently living with their parents, up from 47% in February. The increase was mostly among the younger emerging adults – ages 18 to 24 – and was primarily due to their coming home from colleges that shut down or to their having lost their jobs.


This must view 6 min video signals an emerging architectural and urban design paradigm.

Singapore Has An Innovative New Way To Design Its Buildings

Singapore has engaged a new approach to construction called biophilic design. It means architects embrace nature in their design, bringing nature into the city, replacing columns, walls and neon with trees, leaves and insects. Biophilic design turns cities into engines of environmental wellbeing with benefits not just for nature but the human beings that live there too.


This signals the ongoing progress in the domestication of DNA - and more.

Declared as one of the most important discoveries of the 21st century, CRISPR is faster, cheaper, and more accurate than previous gene-editing systems and has since become ubiquitous in labs around the world.

This is the thing about CRISPR: There’s so many different ways that it can be deployed.

Fresh Off Her Nobel Prize Win, Jennifer Doudna Predicts What’s Next for CRISPR

The new Nobel laureate chats with ‘Future Human’ about what her gene-editing companies are up to.
Doudna, PhD, of the University of California, Berkeley, and Emmanuelle Charpentier, PhD, of the Max Planck Institute in Germany, share the award for the discovery of the gene-editing technology CRISPR. The two biochemists began collaborating in 2011 and just a year later published a groundbreaking paper on CRISPR, which has revolutionized our ability to edit genes.

Short for clustered regularly interspaced short palindromic repeats, CRISPR is actually a naturally occurring bacterial immune system. When viruses attack bacteria, bacteria in turn grab snippets of genetic material from their viral invaders and incorporate these bits into their own DNA. This helps bacteria recognize viruses later on and thwart future invaders. Bacteria do this by producing an RNA molecule that acts as a guide, which cuts up the viral genome.

diseases that are caused by single genes or genetic mutations. A great example, and we’ve already seen early results from one trial, is for sickle cell disease. But I think going forward, we’ll see opportunities to use CRISPR for other kinds of blood disorders, genetic diseases of the eye, and then, maybe in the longer term, cystic fibrosis and muscular dystrophy, which are also genetic diseases.

I think we’re going to see everything from high-throughput laboratory tests that require robotic equipment and experts to point-of-care tests that can be run in a research lab, a doctor’s office, or an emergency room. 

We’ve so much going on in the field. I think one interesting possibility is that we’ll see CRISPR being used not to edit genomes, or at least not to make permanent changes to genomes, but instead to regulate them, to control levels of human proteins that are produced from different genes. This is a newer way of using the CRISPR technology. I think it has a lot of potential to allow control of cells that doesn’t require actual permanent chemical changes being made to the DNA.

Agriculture is the other area where it’s going to be impactful. We’re already seeing a lot of use of CRISPR in making plants that have genetic changes that can enable things like better crop yield, resistance to drought, higher levels of nutritional value, things like that. I think that’s really exciting, and there’s clearly a lot more to be done there. That’s likely to be the area where we’ll see a broader impact in the near term.


The benefits of CRISPR will inevitably extend to the understanding of our microbial biomes. This is a good signal of how microbial transplants will likely be beneficial for treating and maybe curing illnesses and diseases.

Fecal Transfer from Moms to Babies After C-Section: Trial Results

Tiny doses of maternal poo mixed with breast milk and given to Cesarean-born infants makes their gut microbiota resemble those of babies born vaginally.
The composition of gut microbes in babies born via Cesarean section tends to differ from those in babies born vaginally, prompting speculation that this may have long-term health consequences. To enrich for beneficial bugs in babies’ bellies after C-section, researchers have performed mom-to-infant microbial transplants, described today (October 1) in Cell. In a clinical trial in which seven Cesarean-delivered babies were fed tiny amounts of their mothers’ fecal material, it was found that the babies’ guts became colonized with the sorts of bacteria normally present in infants delivered vaginally. While the procedure produced no ill effects in the infants, there are no data on whether it has any benefits to the baby, and experts warn it may be dangerous for mothers to attempt such a treatment themselves.

“This is a very well-balanced, important, and clinically relevant contribution to the field, with really nice, clear-cut conclusions,” says gut microbe researcher Tine Rask Licht of the Technical University of Denmark who was not involved in the research. “They have very nice data . . . [showing that] with fecal transfer they get a pattern of microbial development which is much more similar to that of children born vaginally.”

Epidemiological evidence indicates there may also be later life consequences to missing out on this bacterial baptism, as some call it. A recent study showed that Cesarean-born kids have a higher likelihood of developing immune disorders such as inflammatory bowel disease, rheumatoid arthritis, and celiac disease. The growing prevalence of Cesarean deliveries makes these potential repercussions an increasing concern.


This is another weak signal about energy production, domesticating DNA and an emerging metabolic (circular) economy.

Sludge-powered bacteria generate more electricity, faster

Changing the surface chemistry of electrodes leads to the preferential growth of a novel electroactive bacterium that could support improved energy-neutral wastewater treatment.

To grow, electroactive bacteria break down organic compounds by transferring electrons to solid-state substrates outside their cells. Scientists have utilized this process to drive devices, such as microbial electrochemical systems, where the bacteria grow as a film on an electrode, breaking down the organic compounds in wastewater and transferring the resultant electrons to the electrode.

Scientists are now looking for ways to improve this process so it produces hydrogen gas at a negatively charged cathode electrode, which can then be converted to electricity to power wastewater treatment plants. This needs electroactive bacteria that efficiently transfer electrons to a positively charged anode electrode that do not use hydrogen for their growth.


This is a nice confirming signal of how horizontal gene transfer (hgt) - creates different rules regarding evolution - and help explain that the development of antibiotic resistance is more complex than the normal understanding of evolution would suggest.
"However, when scientists check environments without antibiotics, for example, forests or estuaries, antibiotic resistance genes can still be detected."
The researchers found that antibiotic resistance genes can spread into populations that are not experiencing selection with antibiotic, and that, even though these genes were at low levels, they prepared the population for future challenges with antibiotic.
"This could explain why antibiotic resistance evolves so quickly in hospitals," Dr. McDonald said.

World first study shows that some microorganisms can bend the rules of evolution

The dominant thinking in evolution focuses on inheritance between parent and offspring – or 'vertical gene transfer (VGT)'.

But now scientists are paying more attention to 'horizontal gene transfer (HGT)': the transmission of DNA other than from parent to offspring, as this transfer can tell us about the evolution of a number of other organisms such as bacteria. It can also help us to better understand antibiotic resistance.

In a world first, Monash University scientists have discovered that HGT can bend the rules of evolution.

The discovery is outlined in a study published today in PNAS, which was led by ARC Future Fellow Dr. Mike McDonald and Ph.D. candidate Laura Woods, both from the Monash University School of Biological Sciences.


This is a weak signal of emerging new forms of matter and electronics using graphene - discovered in the 21st Century.

Stacking and twisting graphene unlocks a rare form of magnetism

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.

Now, a team of researchers at Columbia University and the University of Washington has discovered that a variety of exotic electronic states, including a rare form of magnetism, can arise in a three-layer graphene structure.

The findings appear in an article published Oct. 12 in Nature Physics.


Another weak signal of the inevitable need for a metabolic (upcycling) economy. It also signals that simply banning plastics doesn’t solve the problem of waste - it simply shifts it to something else.
Compared to traditional heating, the microwave heating released over 10 times as much hydrogen from the plastic, leaving very little other than pure carbon and some iron carbide behind. Better yet, the carbon was almost entirely in the form of carbon nanotubes, a product with significant value. 

If recycling plastics isn’t making sense, remake the plastics

New catalytic approaches convert plastic into liquid fuels, nanotubes.
A few years back, it looked like plastic recycling was set to become a key part of a sustainable future. Then, the price of fossil fuels plunged, making it cheaper to manufacture new plastics. Then China essentially stopped importing recycled plastics for use in manufacturing. With that, the bottom dropped out of plastic recycling, and the best thing you could say for most plastics is that they sequestered the carbon they were made of.

The absence of a market for recycled plastics, however, has also inspired researchers to look at other ways of using them. Two papers this week have looked into processes that enable "upcycling," or converting the plastics into materials that can be more valuable than the freshly made plastics themselves.


Here’s an account of different browsers in terms of the privacy they enable.

How your browser can make your online life a little more private

A new browser setting will do what Do Not Track didn’t, but you could switch to a more private browser right now.
Data privacy laws are still a work in progress, but one major improvement is coming: Global Privacy Control, which — assuming everything works out — will let you automatically opt out of having your data sold or shared at every website you visit. For now, it doesn’t do much, but it is available if you want to add it to your browser. If nothing else, the recent launch of the new specification is a great opportunity to check out your browser’s privacy options — and your browser options in general.

Trackers hidden on the vast majority of websites collect as much information about us as possible and try to link that data to our actions online as well as off, typically to send us targeted ads. The idea behind Global Privacy Control would be to place a setting on your browser that tells every site you visit that you don’t want your data to be sold or shared with anyone else, and websites would have to respect your wishes. While some browsers have built-in tools (or available extensions) meant to stop tracking in the first place, they aren’t always effective, and they can’t do anything once your data is collected. And while laws like the California Consumer Privacy Act (CCPA) give users the right to request that businesses not sell their data, those users have to make that request of every site they visit, a process that is too time-consuming for most people. With Global Privacy Control, that request would be automatic, relayed as soon as you visit the site, and, if you’re in a location where it’s legally required — like California — websites would have to abide by your request.

If a browser extension that tells websites your privacy preferences sounds familiar, that’s because something like this has been tried before. Do Not Track, introduced in 2010, was an attempt by the Federal Trade Commission (FTC) to institute a sort of digital equivalent to the Do Not Call list: a browser extension or setting that tells websites you visit that you don’t want to be tracked. The problem with Do Not Track was that websites weren’t legally required to comply with it, so very few of them did.

In his Theory of Moral Sentiments (1759), Adam Smith developed a theory of psychology based on ‘sympathy’ and outlined a way of living based on ‘reason and philosophy’. These ideas not only banish the (already disappearing) stereotype of Smith as a pioneer of free-market policies, but challenge some of our most cherished ideas about the sources of happiness.

Published 17 years before The Wealth of Nations (1776), Moral Sentiments begins by rejecting the idea that people are basically self-interested. ‘How selfish soever man may be supposed, there are evidently some principles in his nature which interest him in the fortune of others,’ Smith declares. We are often motivated, and indeed dominated, by our emotional involvement with our ideas about other people, which Smith calls ‘sympathy’.

Sympathy, Smith believed, was inseparable from imagination and from reasoning. We can’t access what other people feel. Instead, we imagine what other people must be feeling, or rather what we believe that we would feel if we were in their position.

Adam Smith warned us about sympathising with the elites




Imagine, though, that it’s possible to invoke a desired property in more or less any material by using light pulses to reshape the way the electrons are distributed. In this view, electron band structure is not something fixed by the material itself: The bands instead become a kind of putty that can be molded into whatever form you desire. Find the right control pulse and you might be able to join an array of mobile electrons into Cooper pairs, say, and thereby make a superconductor, perhaps from some humble substance such as iron or copper, under conditions in which it would otherwise be impossible.

Alchemy Arrives in a Burst of Light




Imagination enables us to leave the here and now, to explore the past, as well as alternative presents and the future, before coming back. Imagination is a loop by which we temporarily disengage from ongoing life. The bored student who looks out of the window, wishing to be in the nearby forest; the dentist’s client browsing a magazine and dreaming about exotic temples; young people demonstrating for the climate – all are imagining.

Imagination is both mundane and fundamental: we imagine when we remember the forest, wonder where stars come from or consider moving home. We also imagine when, on our sofas, we willingly surrender to a film or a novel, taking us to another world. Also, we can imagine alone or with others: sharing imagination, we can deepen our relations, as when we discuss the film we just saw, or we can change the world – as when teams of scientists sent the first rocket to the Moon. Hence, imagination has consequences: it refreshes us, it brings us to understand things, it opens new possibilities, and it can lead us to action, from contacting an old friend to buying a plane ticket.

Imagination is a movement of mind, which can be more or less embodied. It enables us to expand our lived experience, or our ‘lifeworld’, beyond the limitation of the concrete situation we’re in. Children play, and some create imaginary companions; people with particularly vivid imagination build parallel worlds, some of which they describe in novels. These are forms of symbolic mobility. Yet of course another way to expand one’s lifeworld is to move in the physical realm: to travel, to visit the world, to see other places and modes of living. Now, one might wonder, what is the relation between imagination as symbolic mobility and actual geographical mobility?

Nourish your imagination and you will be forever free





Tomora maráŋ is an Ik adage meaning ‘It’s good to share.’

the Ik believe that the landscape is inhabited with spirits called kíʝáwika, which literally means children of the earth. They are believed to bring misfortune to individuals who fail to share with others and to reward those who are especially generous.

This is a fascinating signal of the future of mathematics and knowledge use and creation.
There are huge, important areas of math that have never been fully written down. They’re stored in the minds of a small circle of people who learned their subfield of math from people who learned it from the person who invented it — which is to say, it exists nearly as folklore.

Building the Mathematical Library of the Future

Digitizing mathematics is a longtime dream. The expected benefits range from the mundane — computers grading students’ homework — to the transcendent: using artificial intelligence to discover new mathematics and find new solutions to old problems. Mathematicians expect that proof assistants could also review journal submissions, finding errors that human reviewers occasionally miss, and handle the tedious technical work that goes into filling in all the details of a proof.

But first, the mathematicians who gather on Zulip must furnish Lean with what amounts to a library of undergraduate math knowledge, and they’re only about halfway there. Lean won’t be solving open problems anytime soon, but the people working on it are almost certain that in a few years the program will at least be able to understand the questions on a senior-year final exam.

And after that, who knows? The mathematicians participating in these efforts don’t fully anticipate what digital mathematics will be good for.


Still a weak signal - this is an important step in developing one new computational paradigm.

Neuronlike circuits bring brainlike computers a step closer

For the first time, my colleagues and I have built a single electronic device that is capable of copying the functions of neuron cells in a brain. We then connected 20 of them together to perform a complicated calculation. This work shows that it is scientifically possible to make an advanced computer that does not rely on transistors to calculate and that uses much less electrical power than today’s data centers.

….a major step further and built a circuit with 20 of these elements connected to one another through a network of devices that can be programmed to have particular capacitances, or abilities to store electric charge. He then mapped a mathematical problem to the capacitances in the network, which allowed him to use the device to find the solution to a small version of a problem that is important in a wide range of modern analytics.

The performance of computers is rapidly reaching a limit because the size of the smallest transistor in integrated circuits is now approaching 20 atoms wide. Any smaller and the physical principles that determine transistor behavior no longer apply. There is a high-stakes competition to see if someone can build a much better transistor, a method for stacking transistors or some other device that can perform the tasks that currently require thousands of transistors.

This quest is important because people have become used to the exponential improvement of computing capacity and efficiency of the past 40 years, and many business models and our economy have been built on this expectation. Engineers and computer scientists have now constructed machines that collect enormous amounts of data, which is the ore from which the most valuable commodity, information, is refined. The volume of that data is almost doubling every year, which is outstripping the capability of today’s computers to analyze it.


This isn’t digital smart tattoo as an interface for our bio-computer - yet. A good signal of the future of medical and other sensors.

Engineers print wearable sensors directly on skin without heat

Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Led by Huanyu "Larry" Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, the team published their results in ACS Applied Materials & Interfaces.

"In this article, we report a simple yet universally applicable fabrication technique with the use of a novel sintering aid layer to enable direct printing for on-body sensors," 

The sensors are capable of precisely and continuously capturing temperature, humidity, blood oxygen levels and heart performance signals, according to Cheng. The researchers also linked the on-body sensors into a network with wireless transmission capabilities to monitor the combination of signals as they progress.

The process is also environmentally friendly, Cheng said. The sensor remains robust in tepid water for a few days, but a hot shower will easily remove it.
"It could be recycled, since removal doesn't damage the device," Cheng said. "And, importantly, removal doesn't damage the skin, either. That's especially important for people with sensitive skin, like the elderly and babies. The device can be useful without being an extra burden to the person using it or to the environment."


And here’s a signal about self-powering devices and sensors.

Easy-to-make, ultra-low power electronics could charge out of thin air

Researchers have developed a new approach to printed electronics which allows ultra-low power electronic devices that could recharge from ambient light or radio-frequency noise. The approach paves the way for low-cost printed electronics that could be seamlessly embedded in everyday objects and environments.

researchers from the University of Cambridge, working with collaborators from China and Saudi Arabia, have developed an approach for printed electronics that could be used to make low-cost devices that recharge out of thin air. Even the ambient radio signals that surround us would be enough to power them. Their results are published in the journal ACS Nano.

The technology developed by the researchers delivers high-performance electronic circuits based on thin-film transistors which are 'ambipolar' as they use only one semiconducting material to transport both negative and positive electric charges in their channels, in a region of operation called 'deep subthreshold' – a phrase that essentially means that the transistors are operated in a region that is conventionally regarded as their 'off' state. The team coined the phrase 'deep-subthreshold ambipolar' to refer to unprecedented ultra-low operating voltages and power consumption levels.


This is an interesting small signal regarding the transformation of transportation - recalling the projected future of the 1950s

France to test 'flying taxis' from next year: operators

"Flying taxis" will start taking off from an aerodrome north of Paris as soon as next June, operators said, in a trial ahead of a vast tourist influx for the 2024 Olympics.
The experiment will take place at the Pontoise-Cormeilles-en-Vexin aerodrome some 90 minutes northwest of the capital by car, according to a joint announcement by the Ile-de-France region, airports operator Groupe ADP and the RATP public transport agency.


A good signal of the progress being made in self-driving vehicles.

Waymo removing backup drivers from its autonomous vehicles

Waymo is allowing the general public to hitch a ride in its driverless autonomous vehicles in Phoenix, expanding a service it had been quietly offering to a select group of riders for the past year.

The service launches to the general public Thursday. The vehicles, which will have no back-up drivers behind the wheel to take over in sticky situations, will serve an area of 50 square miles. There won't be anyone watching remotely who can take over in an emergency and drive the car.

Before the coronavirus struck, which reduced demand for rides, Waymo was providing 1,000 to 2,000 rides in autonomous vehicles per week. Most of the rides had a backup driver behind the wheel, but 5% to 10% of the rides were without a human backup driver and were available only to a smaller group of riders who signed non-disclosure agreements. Waymo did not disclose how many fully autonomous vehicles will be available to the public in the Phoenix area.


This is a great signal of the affordances of AI, self-driving vehicles and big data in increasing our capacity to grow more and better food.

Alphabet's X lab announces "Mineral" project to increase sustainable food production

Alphabet's X lab, formerly a Google division, has announced via blog post that it has formally named its newest "moonshot" project Mineral. The project will be geared toward using new and novel methods to increase sustainable food production. Alphabet X has also set up a web page outlining the goals of the project.

As noted on the team's blog post, to feed the billions of people expected to be populating the Earth in the coming years, changes are required in food production. The team at Mineral suggests that such changes should involve the use of new approaches, techniques and tools. Such tools and techniques, they say, should involve the development of new kinds of hardware, software and the way they are built and used in agricultural efforts.

One example is a robotic buggy that the team has deployed in several locations. Each of the robots drives over cropland along the same paths used by tractors so as to not disturb the plants, autonomously collecting data. Each plant is photographed and sensors collect data about the plant and the soil in which it is growing. The data from the robots is then analyzed and used to make changes to farming practices that will result in greater yields.


And another strong signal of the growing use and possibilities of self-driving and self-energizing AI machines and sensors

"2020 will begin a decade of climate action," Chen says. "Big companies are looking to reduce their carbon emissions and they're looking to forests to see how these resources can be used to assist them in this effort. We need to know what's going on in the forest. Data will help us do that."

Not only will this data provide much needed insight into the health of forests, but the current lack of data has devastating effects.

Treeswift's autonomous robots take flight to save forests

Chen founded Treeswift as a spin-off company from Penn Engineering's GRASP Lab. The idea behind it is simple: use robotic tools to automate forestry and reduce risk for human workers. Treeswift uses swarms of autonomous, flying robots equipped with LiDAR sensors to monitor, inventory, and map timberland. The drones collect images of the land and render them into 3-D maps that can be analyzed for precise, quantifiable measurements of a given forest's biomass.

Of the variety of applications this data has, Treeswift is focused on three main targets: calculating inventory for the timber industry, mapping forests for preservation, and measuring forest biomass and fuel to prevent the spread of wildfires. The collected data can be used by researchers in a variety of industries to assess the health of forests and build predictive models that can aid in climate change action initiatives.


Now if we think of these drones as mobile sensors meshwork linked with each other and AI and satellites and Google Earth (or something like it) as a virtual world (like Second Life) - we can begin to image what affordances can be enabled for a new form of consciousness

Satellites could soon map every tree on Earth

An analysis of satellite images has pinpointed individual tree canopies over a large area of West Africa. The data suggest that it will soon be possible, with certain limitations, to map the location and size of every tree worldwide.
Terrestrial ecosystems are defined in large part by their woody plants. Grasslands, shrublands, savannahs, woodlands and forests represent a series of gradations in tree and shrub density, from ecosystems with low-density, low-stature woody plants to those with taller trees and overlapping canopies. Accurate information on the woody-vegetation structure of ecosystems is, therefore, fundamental to our understanding of global-scale ecology, biogeography and the biogeochemical cycles of carbon, water and other nutrients. Writing in Nature, Brandt et al. report their analysis of a massive database of high-resolution satellite images covering more than 1.3 million square kilometres of the western Sahara and Sahel regions of West Africa. The authors mapped the location and size of more than 1.8 billion individual tree canopies; never before have trees been mapped at this level of detail across such a large area.

The spatial resolution of most satellite data is relatively coarse, with individual image pixels generally corresponding to areas on the ground that are larger than 100 square metres, and often larger than one square kilometre. This limitation has forced researchers in the field of Earth observation to focus on measuring bulk properties, such as the proportion of a landscape covered by tree canopies when viewed from above (a measurement known as canopy cover).


The more we change - the more we have changed. An interesting signal of emerging human evolution.
this study into the prevalence of the artery over generations shows that modern humans are evolving at a faster rate than at any point in the past 250 years.

Forearm artery reveals humans evolving from changes in natural selection

Humans haven't developed genetic mutations for telepathy or superpowers just yet, but a new study shows our species is still evolving in unique ways and changes in the natural selection could be the major reason.

An investigation by Dr. Teghan Lucas at Flinders University and Professor Maciej Henneberg and Dr. Jaliya Kumaratilake at the University of Adelaide published in the Journal of Anatomy has shown a significant increase in the prevalence of the median artery in humans since the late 19th century.

The median artery is the main vessel that supplies blood to the human forearm and hand, when first formed in the mother's womb but it disappears once two arteries seen in adults develop. But many people now retain the median artery for their whole life in addition to the other two arteries (about one in three).

This evolutionary trend will continue in those born 80 years from today, with the median artery becoming a common in the human forearm.


This is a strong signal of the emerging strength of the artisanal movement for food and drink - unlike industrial grade mass produced food - unprocessed food varies like with with season and terroir.

How to enjoy coffee

Smooth like chocolate or fruity like a berry, coffee has as many tastes as wine or beer – you just need to know your beans
Coffee hasn’t always received the attention it deserves. In many Western countries especially, the beans were low quality. Drinkers didn’t know or care about how coffee was produced, bought or brewed. A lot of coffee was cheap and tasted bitter, and its purpose was practical: medicine or fuel.

But over the past few decades, things have started to change around the world. A global band of intrepid producers, buyers, roasters, baristas and scientists have been elevating coffee to the craft level, like fine wine and beer. You might think that you know what coffee tastes like – roasted, toasty and bitter – but that’s only a sliver of the variety available to you now.

Coffee – what’s called ‘drip’ or ‘filter’ coffee, not espresso – can taste smooth and sweet like chocolate, or provide a zip on your tongue like a bright Champagne, or taste fruity, just like a blueberry. And when I say ‘chocolate’ or ‘blueberry’, I mean the coffee itself literally tastes like those things, without any added syrups or flavourings. The first time you drink coffee that tastes like more than coffee, you’ll never forget it.

This expansion of flavours is partly down to a global trend towards new roasting techniques. All coffee roasters create a roast profile – a manipulation of time and temperature – to achieve flavour in the beans. Historically, coffee has been roasted for relatively long periods of time at relatively high temperatures (think of traditional Italian coffee culture or the giant coffee chains in the United States). This profile tends to emphasise roast character, the flavours imparted by the roasting process – akin to how the process of ageing bourbon in oak barrels imparts a distinct flavour to the spirit. But more recently, distinct coffee cultures – including those of North America, Australia, Britain, Scandinavia and Japan – have been pushing other roasting techniques forward, ones that focus on the qualities of the bean. For example, roasting at relatively low temperatures for a shorter amount of time tends to accentuate what I call coffee character, the unique flavours inherent in the bean itself and where it was grown – or its terroir, to borrow a term from wine.


We are in the midst of crazy times - climate change - covid apocalypse - crises of democracy - it’s hard to not get depressed - but here’s a great signal of when depression provides delight and secret satisfactions. The videos are the magic antidepressant elixir. 

The Hydraulic Press Channel Is the Internet Sensation of Our Time

We spoke to the creative minds behind the channel about the human need to destroy. 

Lauri and Anni Vuohensilta have been crushing it. The Finnish couple began pulverizing random objects under a 150-ton hydraulic press at their family’s factory five years ago this month, carving out their own genre of “satisfying” internet videos and amassing more than 10 million followers across major social media platforms in the process.


On a video call, I interviewed the Vuohensiltas about what’s left to crush, why the channel appeals to so many people, Lauri’s delightful accent, the effects of the coronavirus on their hydraulic pressing, and how people who don’t have a hydraulic press can fulfill their human need for destruction.
