Friday Thinking 4 Dec 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.

All of this is part of a much larger shift in the very scope of science, from studying what is to what could be. In the 20th century, scientists sought out the building blocks of reality: the molecules, atoms and elementary particles out of which all matter is made; the cells, proteins and genes that make life possible; the bits, algorithms and networks that form the foundation of information and intelligence, both human and artificial. This century, instead, we will begin to explore all there is to be made with these building blocks.

For even with 14 billion years of an expanding universe and almost 4 billion years of life on Earth, nature has explored only the tiniest fraction of all of the possible designs.

The natural processes on Earth and in the universe have produced only a small sample of the full menu of molecules and forms of matter, and consequently of the corresponding laws of physics they will have to obey.

Nature’s agonizingly slow process of discovery, driven by cosmological and biological evolution on time scales of millions and billions of years, is accelerated to breakneck speeds in the laboratory. Such work might feel, at first, like “artificial” science. But a genetically designed bacterium is in no way less real, or less worthy of study, than one found in the wild. Nor are the novel one- and two-dimensional materials that display the curiosities of quantum theory. Rather, such new technologies effectively “liberate” quantum mechanics from the confines of atoms and molecules and bring it to the macroscopic scales of everyday life. At some point, we will be able to order every item on the menu of reality.

Contemplating the End of Physics




While peripersonal space first evolved for self-defence, then, its mechanisms have clearly been recycled to take advantage of opportunities in the immediate surroundings. This shift of function is in line with our general understanding of how evolution works by co-opting or recycling existing resources for new uses. ‘Evolution does not produce novelties from scratch. It works on what already exists, either transforming a system to give it new functions or combining several systems to produce a more elaborate one,’ as the Nobel laureate François Jacob put it.

This process is known formally as exaptation. While an adaptation is a new trait that was selected for the way it improved an organism’s fitness, exaptations retool existing useful structures for new purposes. A classic example of exaptation concerns the role of feathers in birds, which would have been originally selected due to their role in thermoregulation and only later co-opted for flight. Some cognitive abilities (maybe most of them) can also be conceived of as exaptations of existing brain resources: brain regions aren’t dedicated to a single task but are recycled to support numerous cognitive abilities. Recycling makes sense from an evolutionary perspective, since it’s more efficient than developing whole new neural systems.

How close is too close?




Human beings are storytelling creatures: we spin narratives in order to construct our world. Whether on the cave walls of Lascaux or the golden record stored on the Voyager spacecraft, we want to share our selves and what matters to us through words, actions, even silence. Self-making narratives create the maps of the totality of our physical reality and experiences – or, as philosophers sometimes say, of the lifeworlds that we inhabit. And just as narratives can create worlds, they can also destroy them.

Trauma is not a virus to be medicated away, nor a tale to be forgotten, nor a deep sadness to be replaced with reckless optimism. What it can be is a catalyst for different stories – better stories – about who we are, what we value, and how we might live in the ‘after’. And these stories are not happiness-seeking – they are meaning-making, meaning-remaking. They are the narratives of tragic optimism that don’t fall prey to comfortable amnesias or myths of human invulnerability. They harbour no illusions about the indestructibility of our worlds. Perhaps if we engage with our traumas less reluctantly and open up to the possibilities of narrative world-remaking, we might integrate some of our worst experiences into the ever-evolving stories about who we are. However uneasily, we just might coexist with, and even flourish in, their glare. Because trauma can, and will, unmake our worlds again.

Trauma unmakes the world of the self. Can stories repair it?




I do want to say something about leadership.  Leadership is the art of getting the public to pay attention to something that it often doesn't want to pay attention to.  Leadership takes guts.  Public leadership is the hardest of all.  When the Kennedys and before them FDR paid attention and got the public to pay attention to what it needs to pay attention to, they did not rely on polls.  You can't lead the public to where it already is because it's already there.  That's what polls tell you.  You can't educate the public about what it doesn't want to be educated if you are catering and pandering to a public that already has certain preconceptions. 

JOHN KENNETH GALBRAITH: HIS LIFE AND TIMES




We are in a time of change in the conditions of change - where the simple is too often the argument for making our problems and discussions simplistic. This is an important signal of the looming crisis of legitimacy of our systems and institutions.
my first lesson from Dynamics in Action. At the level of a system such as representative democracy, cause and effect function in unexpected ways. It’s remarkable how powerful a hold Newton’s idea of billiard-ball causation has on the modern mind: we speak rather glibly of “social forces,” “political movements,” and “revolutions” as if there were a mechanics of human affairs, and we are constantly predicting events with the confidence of an astronomer announcing a solar eclipse.

The Rise and Fall of Institutions

Alicia Juarrero shows how to think big about democracy
A characteristic of our strange moment in history is our fixation with details and our indifference to the big picture. It should be clear, to anyone with eyes to see, that the institutions of representative democracy are maladapted to the digital age. The democratic system—let’s agree to call it that—has lost the public’s trust and is bleeding out authority. Street revolts and populism are increasingly the result. For those who care about democracy, one would think that adapting the system to digital technology in a way that embraces and reconciles the public would be the main topic of discussion. Instead, we obsess about Donald Trump’s latest tweet, or Dr. Anthony Fauci’s latest thought on surgical masks, or Black Lives Matter’s latest assertion that the great threat to American freedom is posed by urban police departments.
It’s as if we can’t see the forest for a leaf.

If we wish to reform our democratic institutions, we should probably focus on structure rather than noise and raise up our eyes from the parts to the whole. Complex systems like our democracy, it turns out, are found everywhere in natural and human arrangements, and in all cases, they behave in a broadly similar manner. They go through a particular life cycle. In recent decades, a group of scholars has dedicated considerable ingenuity to studying the behavior of existing systems. And, though much remains to be learned, these specialists have uncovered fascinating patterns that can help us think about our institutions from the perspective of the big picture.


This is an important signal in these days of looming authoritarianism and anxieties for the future of democracy. Many social animals use systems of quorum sensing to make decisions - a deep foundation for evolving democratic institutions - that can enable group commitments.

Alpha animals must bow to the majority when they abuse their power

Many animal groups decide where to go by a process similar to voting, allowing not only alphas to decide where the group goes next but giving equal say to all group members. But, for many species that live in stable groups—such as in primates and birds—the dominant, or alpha, group members often monopolize resources, such as the richest food patches and access to mates. Scientists at the Max Planck Institute of Animal Behavior and the Cluster of Excellence Centre for the Advanced Study of Collective Behavior at the University of Konstanz have studied the links between dominance and group decision-making in wild vulturine guineafowl. They report that democratic decision-making plays an essential role in mitigating the power of alphas by deciding where to move next if those alphas are monopolizing resources.

While it had long been thought that alphas lead the way and decide where the group moves next, studies over the past decade have suggested that all group members can have equal say by 'voting' for where the group goes next. However, it has remained to be determined whether this form of democratic decision-making exists in order to keep the power of dominants in check. "Working together as a group is critical for these birds, as their bright plumage makes isolated individuals easy targets for predators such as leopards and martial eagles," says Damien Farine, the senior author of the study and lead research on the vulturine guineafowl project.

When groups were feeding in large spacious areas, where distributed food was equally accessible to everyone, then all group members contributed equally. However, when dominant individuals monopolized a particularly rich food patch—chasing other group members out—then the excluded subordinates combined their votes to move the group away from the patch, ultimately forcing the dominants to abandon their rich resources. These findings suggest democratic decision-making, as opposed to despotic leadership, has evolved so that all group members can obtain the resources (e.g. food and water) that they need to survive. This would not be possible if dominant individuals always decided what was best for themselves.


A good signal in ongoing progress in the development of alternative intelligence - another stage of applications now loom.
The ability to accurately predict protein structures from their amino-acid sequence would be a huge boon to life sciences and medicine. It would vastly accelerate efforts to understand the building blocks of cells and enable quicker and more advanced drug discovery.
AlphaFold came top of the table at the last CASP — in 2018, the first year that London-based DeepMind participated. But, this year, the outfit’s deep-learning network was head-and-shoulders above other teams and, say scientists, performed so mind-bogglingly well that it could herald a revolution in biology.

‘It will change everything’: DeepMind’s AI makes gigantic leap in solving protein structures

Google’s deep-learning program for determining the 3D shapes of proteins stands to transform biology, say scientists.
An artificial intelligence (AI) network developed by Google AI offshoot DeepMind has made a gargantuan leap in solving one of biology’s grandest challenges — determining a protein’s 3D shape from its amino-acid sequence.

DeepMind’s program, called AlphaFold, outperformed around 100 other teams in a biennial protein-structure prediction challenge called CASP, short for Critical Assessment of Structure Prediction. The results were announced on 30 November, at the start of the conference — held virtually this year — that takes stock of the exercise.

“This is a big deal,” says John Moult, a computational biologist at the University of Maryland in College Park, who co-founded CASP in 1994 to improve computational methods for accurately predicting protein structures. “In some sense the problem is solved.”


Covid is not only a huge signal in itself - but it should be signalling many reasons to re-imagine and re-form our institutions.
The 18 years of research done by the UBC team in developing Glybera was paid for by the Canadian Institutes of Health Research, a government agency that funds basic medical research in Canada.
In fact, it is usually public money that funds the development of a new drug, even in a free enterprise haven like the United States. 

That Time Canada Had a Public Lab that Made Life-saving Drugs

We spend $1 billion on medical research, but have no ownership of the products. That wasn’t always the case.
Created before the First World War, the publicly owned Connaught Labs produced vital drugs for Canadians. It was privatized in the 1980s.
A team of medical researchers at the University of British Columbia spent almost two decades developing the drug Glybera before it was eventually brought to market. Glybera turned out to be remarkably effective — capable in a single dose of treating a rare, deadly genetic disorder known as LPLD, which happens to be particularly prevalent among people living in the area around Saguenay, Quebec.

Yet, in April 2017, for purely business reasons, Glybera was withdrawn from the market and this highly effective drug is no longer available anywhere in the world.

The story of Glybera demonstrates much about what is terribly wrong with today’s pharmaceutical industry, where multinational corporations make life-and-death decisions for reasons that are related exclusively to their profitability.

But it also raises the question of whether the outcome of this sad tale could have been very different — if Canada’s unique, publicly owned pharmaceutical company, Connaught Labs, had remained in operation, rather than being sold off by the Canadian government as part of a wave of privatizations in the 1980s.


This is a strong signal of the relationship between our wellbeing the the microbial ecology that we depend on and are entangled with.
we collected daily samples so we could really see what was happening day to day," Dr. van den Brink says. "The changes in the microbiota are rapid and dramatic, and there is almost no other setting in which you would be able to see them."

Study is the first to link microbiota to dynamics of the human immune system

Memorial Sloan Kettering Cancer Center researchers have uncovered an important finding about the relationship between the microbiota and the immune system, showing for the first time that the concentration of different types of immune cells in the blood changes in relation to the presence of different bacterial strains in the gut.

In recent years, the microbiota—the community of bacteria and other microorganisms that live on and in the human body—has captured the attention of scientists and the public, in part because it's become easier to study. It has been linked to many aspects of human health.

A multidisciplinary team from Memorial Sloan Kettering has shown for the first time that the gut microbiota directly shapes the makeup of the human immune system. Specifically, their research demonstrated that the concentration of different types of immune cells in the blood changed in relation to the presence of different bacterial strains in the gut. The results of their study, which used more than ten years of data collected from more than 2,000 patients, is being published November 25, 2020, in Nature.


This is an important signal of several horizons - renewable energy - domesticating DNA - and microbial manufacturing.

Research creates hydrogen-producing living droplets, paving way for alternative future energy source

Scientists have built tiny droplet-based microbial factories that produce hydrogen, instead of oxygen, when exposed to daylight in air.

The findings of the international research team based at the University of Bristol and Harbin Institute of Technology in China, are published today in Nature Communications.

Normally, algal cells fix carbon dioxide and produce oxygen by photosynthesis. The study used sugary droplets packed with living algal cells to generate hydrogen, rather than oxygen, by photosynthesis.


Another strong signal in the ongoing process of making more of Moore’s Law.

Trillion-transistor chip breaks speed record

The biggest computer chip in the world is so fast and powerful it can predict future actions "faster than the laws of physics produce the same result."
That's according to a post by Cerebras Systems, a startup company that made the claim at the online SC20 supercomputing conference this week.

Working with the U.S. Department of Energy's National Energy Technology Laboratory, Cerebras designed what it calls "the world's most powerful AI compute system." It created a massive chip 8.5 inch-square chip, the Cerebras CS-1, housed in a refrigerator-sized computer in an effort to improve on deep-learning training models.

Cerebras team leader Michael James and the Department of Energy's Dirk Van Essendelft said in their paper that the CS-1, powered by 1.2 trillion transistors, performed at 200 times the speed of a Joule supercomputer in a simulation of powerplant combustion processes. They said the chip's performance cannot be matched by current supercomputers regardless of the number of CPUs and GPUs they house.


This is a strong signal of the future of manufacturing all manner of nanodevices for all manner of quantum reasons - there’s a great 15 min video illustrating and explaining the process.

Physicists invent printable superconducting device

Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicists invented a method to 3-D-print these and other superconducting devices in minutes.

"Fabricating superconducting devices on a computer chip is a multi-step and demanding procedure, requiring dedicated facilities," says Kaveh Lahabi, a physicist at Leiden University. "It usually takes days to complete,"

Lahabi and co-authors have developed a new approach, in which Josephson junctions, essential parts of SQUIDS, can be printed on almost any surface in mere minutes, within an electron microscope.

In this video, Lahabi and co-author Tycho Blom demonstrate their technique and discuss their recent article in ACS Nano.


A signal - to the world that we need to re-imagine how we make and metabolize everything - rather than banning individual types of matter (e.g. plastic straws) we should phase in a ban on all sorts of landfill (airfill and waterfill) - which is a ban on all garbage except food - which we can metabolize as compost for growing food.

China to end all waste imports on Jan 1

China will ban all waste imports from January 1, 2021, state media reported Friday, marking the culmination of a three-year phase-out of accepting overseas junk. 
Since the 1980s the country has imported solid waste, which local companies would clean, crush and transform into raw materials for industrialists. For years it has been the world's largest importer of rubbish, often leading to pollution when the materials cannot be recycled or disposed of properly. 

Hoping to no longer be the world's rubbish bin, the government started to close China's doors to foreign waste in January 2018, causing backlogs of garbage in the exporting countries. Since then, it has gradually banned imports of different types of plastics, car parts, paper, textiles, and scrap steel or wood.

And from January 1 the ban will cover all kinds of waste, according to the Xinhua news agency.

the puzzlingly irrational narrowness of the rulebook for scientific argument turns out to have an upside, driving determined scientists to produce a great, Nobel Prize-winning experiment.

Such salutary consequences are, I believe, quite general. The rulebook says, in effect, that if you want to make an argument in science – if you want to win an argument in science – then you must undertake complex, involved, sometimes almost interminable projects that most reasonable people, even inveterate truth-seekers, would prefer to avoid. In this way, the narrowness of the rules channels scientific energy and ambition down specific, often rather long and arduous, paths. But it is at the end of just these paths that the most revealing evidence is found, the observable facts that discriminate most clearly between competing theories or that push thinkers, searching for explanations, to devise entirely new ideas.

Keep science irrational





But what is creativity? It turned out that the field of psychology already had an answer. In 1950, J P Guilford, president of the American Psychological Association, had described his dissatisfaction with conventional explanations of human intellectual ability. They focused on convergent thinking: the ability to find and reproduce the right answer, such as 2 + 2 = 4. That’s vital to our lives, but Guilford argued that it’s not all that matters. Our ability to generate many possible answers to a problem is also important – in other words, divergent thinking. If the question is ‘What equals 4?’ there is no single, correct answer. It could be 2 + 2, but it could also be 3 + 1, or even 0.25 + 3.75. Divergent thinking would come to be seen as a hallmark of creativity.

psychologists would come to understand that creativity is not merely a matter of how we think, but also a function of our personalities (some people are inclined to be more open-minded than others) and where we work or learn (some environments are more conducive to creativity than others, for example through encouraging free thinking). When all of these factors are favourably aligned, people are more likely to be able to generate ideas and products that solve problems in new and useful ways.

Recognise the creativity behind crime, then you can thwart it





Another interesting signal - this time from The Lancet - of how gaming can be incorporated to help in all manner of citizen science. Something that could also enable all sorts of people (with support of a Universal Basic Income) create value for society - even if they don’t have a ‘job’.

The untapped potential of virtual game worlds to shed light on real world epidemics

Simulation models are of increasing importance within the field of applied epidemiology. However, very little can be done to validate such models or to tailor their use to incorporate important human behaviours. In a recent incident in the virtual world of online gaming, the accidental inclusion of a disease-like phenomenon provided an excellent example of the potential of such systems to alleviate these modelling constraints. We discuss this incident and how appropriate exploitation of these gaming systems could greatly advance the capabilities of applied simulation modelling in infectious disease research.

On Sept 13, 2005, an estimated 4 million players1 of the popular online role-playing game World of Warcraft (Blizzard Entertainment, Irvine, CA, USA) encountered an unexpected challenge in the game, introduced in a software update released that day: a full-blown epidemic. Players exploring a newly accessible spatial area within the game encountered an extremely virulent, highly contagious disease. Soon, the disease had spread to the densely populated capital cities of the fantasy world, causing high rates of mortality and, much more importantly, the social chaos that comes from a large-scale outbreak of deadly disease (figure 1 and webfigure). These unforeseen effects raised the possibility for valuable scientific content to be gained from this unintentional game error, and it is this possibility that we will examine.


This is a signal of one inevitable result of AI capability - as McLuhan noted when we are facing information overload - we have to shift to pattern re-cognition. And of course this approach enhances our efforts to create more powerful knowledge management tools.
Preliminary testing suggests that the tool helps readers to sort through search results faster than viewing titles and abstracts, especially on mobile phones, he says. “People seem to really like it.”
“I predict that this kind of tool will become a standard feature of scholarly search in the near future. Actually, given the need, I am amazed it has taken this long to see it in practice,” says Jevin West, an information scientist at the University of Washington in Seattle who tested the tool at Nature’s request. “It is not perfect, but it’s definitely a step in the right direction,” he says.

tl;dr: this AI sums up research papers in a sentence

Search engine’s tool for summarizing studies promises easier skim-reading.
The creators of a scientific search engine have unveiled software that automatically generates one-sentence summaries of research papers, which they say could help scientists to skim-read papers faster.

The free tool, which creates what the team calls TLDRs (the common Internet acronym for ‘Too long, didn’t read’), was activated this week for search results at Semantic Scholar, a search engine created by the non-profit Allen Institute for Artificial Intelligence (AI2) in Seattle, Washington. For the moment, the software generates sentences only for the ten million computer-science papers covered by Semantic Scholar, but papers from other disciplines should be getting summaries in the next month or so, once the software has been fine-tuned, says Dan Weld, who manages the Semantic Scholar group at AI2 and led the work.

The TLDR software is not the only scientific summarizing tool: since 2018, the website Paper Digest has offered summaries of papers, but it seems to extract key sentences from text, rather than generate new ones, Weld notes. TLDR can generate a sentence from a paper’s abstract, introduction and conclusion. Its summaries tend to be built from key phrases in the article’s text, so are aimed squarely at experts who already understand a paper’s jargon. But Weld says the team is working on generating summaries for non-expert audiences.


Our understanding of the future and the past is increasing with the progress being made in AI analysis.

Mapping the genetic relations between ancient populations

New mathematical tools have improved our ability to interpret the information contained in ancient DNA samples. Bioinformaticians have developed a model that can visualise the migrations and gene flows of populations from prehistoric Europe.

Archaeological sites and museum collections are invaluable not only from a cultural perspective, but also for biological purposes. Indeed, they contain ancestral human DNA, as well as precious elements for retracing the history of humankind and the movements of prehistoric populations. Archaeology and anthropology have long surveyed the evidence of this humanity from the past, and have provided a great deal of data regarding its evolution and connection with today’s societies. 

Paleogenomics and bioinformatics have now taken over the analysis of ancient genomes. "Mathematical studies of populations have become an essential complement to biological studies, especially when trying to represent the links between genomes," explains Olivier François, a researcher at the TIMC-Imag laboratory. His research, conducted in collaboration with CNRS researcher Flora Jay from the Laboratory for Computer Science (LRI), recently featured in Nature Communications.


Here’s a signal of the future of the colonoscopy - and maybe other types of internal examinations.

A capsule to explore the intestine

A Paris-based research team has developed a capsule to swallow that will produce images and 3D maps of the intestine. A new era is dawning in colorectal cancer screening.

Undergoing a colonoscopy under anaesthetic is certainly not much fun, so to spare their patients the discomfort, physicians will soon be able to give them a small technological miracle to swallow: an endoscopic capsule equipped with a camera and 3D imaging system. The size of a large olive, this autonomous probe called Cyclope will then travel through the digestive tract, where it will produce a detailed map of the colon and intestine. If abnormalities such as polyps are present, the capsule will be able to detect them.

Cyclope will be equipped with a megapixel camera and LED lighting that will generate high-definition images. Above all, it will contain an imaging system able to map the interior of the colon with an accuracy close to 90%. To achieve this, the capsule will project a laser pattern on the intestinal wall and based on deformation of this pattern by the volume of the digestive tract, it will be able to reconstitute its relief.


Another signal of the power of CRISPR - to treat diseases.

Revolutionary CRISPR-based genome editing system treatment destroys cancer cells

Researchers at Tel Aviv University (TAU) have demonstrated that the CRISPR/Cas9 system is very effective in treating metastatic cancers, a significant step on the way to finding a cure for cancer. The researchers developed a novel lipid nanoparticle-based delivery system that specifically targets cancer cells and destroys them by genetic manipulation. The system, called CRISPR-LNPs, carries a genetic messenger (messenger RNA), which encodes for the CRISPR enzyme Cas9 that acts as molecular scissors that cut the cells' DNA.

The revolutionary work was conducted in the laboratory of Prof. Dan Peer, VP for R&D and Head of the Laboratory of Precision Nanomedicine at the Shmunis School of Biomedicine and Cancer Research at TAU. The research was conducted by Dr. Daniel Rosenblum together with Ph.D. student Anna Gutkin and colleagues at Prof. Peer's laboratory, in collaboration with Dr. Dinorah Friedmann-Morvinski from the School of Neurobiology, Biochemistry & Biophysics at TAU; Dr. Zvi R. Cohen, Director of the Neurosurgical Oncology Unit and Vice-Chair of the Department of Neurosurgery at the Sheba Medical Center; Dr. Mark A. Behlke, Chief Scientific Officer at IDT Inc. and his team; and Prof. Judy Lieberman of Boston Children's Hospital and Harvard Medical School.

The results of the groundbreaking study, which was funded by ICRF (Israel Cancer Research Fund), were published in November 2020 in Science Advances.


Another great signal for about our capacity to meet some of the challenges of clean water and bacterial infections.

Nature's toolkit for killing viruses and bacteria

They burst out of toilet bubbles, swim across drinking water, spread through coughs. Tiny infectious microbes—from the virus that causes COVID-19 to waterborne bacteria—kill millions of people around the world each year. Now engineers are studying how zinc oxide surfaces and natural hydrodynamic churning have the power to kill pathogens first.

"Bacterial contamination of common surfaces and of drinking water have been traditionally the main infection routes for transmission of serious diseases, often leading to mortality," said Abinash Tripathy, a researcher in mechanical and process engineering at ETH Zurich. "Our goal was to design a surface that can address both issues."

His group submerged clean zinc in hot water for 24 hours, which formed a zinc oxide surface covered in sharp nanoneedles. Then they introduced E. coli bacteria.

The surface kills almost all bacteria cultured on top of it very efficiently. And the biggest surprise? When sitting in contaminated water, the surface kills all waterborne E. coli within three hours—even bacteria it didn't touch.

This water disinfection at a distance works because the process generates a reactive oxygen species, which damages the cell walls of bacteria. The group from ETH Zurich, IIT Ropar India, and Empa, Switzerland, presented their initial findings at the 73rd Annual Meeting of the American Physical Society's Division of Fluid Dynamics.


As if Climate Change isn’t enough (along with everything else) - here’s an important signal that may well challenge the next generation to advance our space capacities.

Apophis asteroid might be more likely to strike Earth in 2068 than thought

The asteroid Apophis was first spotted by astronomers back in 2004. Shortly thereafter, researchers worked out its orbital path and found that the 340-meter-wide asteroid would pass near to the Earth in 2029, 2036 and again in 2068. More study showed that there was little chance of the asteroid striking Earth; thus, it was discounted as a threat. More recently, Tholen and his team noted that earlier researchers had not accounted for the Yarkovsky effect by which rays from the sun strikes one side of an asteroid. As the heat radiates away from the asteroid, a small amount of energy pushes back against the asteroid, forcing it to turn slightly. Tholen and his team calculated that the Yarkovsky effect is pushing Apophis to one side enough to force it to drift by approximately 170 meters a year. They next applied that bit of knowledge to the math describing Apophis's orbit and found that the drift is changing the course of the asteroid in a way that will bring it closer to Earth. He notes that thus far, there is no indication that the asteroid will strike the Earth in 2029 and 2036, but 2068 might be another matter. He suggests that astronomers will have to keep an eye on Apophis as its rendezvous date approaches.


On the other hand - this sounds like Star Trek - in another way.
"We can imagine a future where this technology may induce electrical discharge from passing lightning, helping to guide it to safe targets and reduce the risk of catastrophic fires."

New tractor beam has potential to tame lightning

An international team of researchers, including scientists from The Australian National University (ANU) and UNSW Canberra, are pioneering laser tractor beam technology that has the potential to control the path and direction of lightning.

Co-researcher Dr. Vladlen Shvedov, from the ANU Research School of Physics, said the team used a laser beam that mirrors the same process as lightning and creates a path that directs electrical discharges to specific targets.

The beam works by trapping and heating graphene microparticles in the ambient air. By heating the graphene microparticles trapped in the beam, the team was able to create the necessary conditions for electric breakdown and transmission along the laser's path using only an ordinary low-intensity laser,


The fabulous marketing of diamonds (as forever) enabled companies to sell diamonds in a way that would more likely keep them off the resale market - even with the advent of artificial diamonds - not they become way more useful even if they become way cheaper.

Scientists make insta-bling at room temperature

An international team of scientists has defied nature to make diamonds in minutes in a laboratory at room temperature—a process that normally requires billions of years, huge amounts of pressure and super-hot temperatures.

The team, led by The Australian National University (ANU) and RMIT University, made two types of diamonds: the kind found on an engagement ring and another type of diamond called Lonsdaleite, which is found in nature at the site of meteorite impacts such as Canyon Diablo in the US.

This new unexpected discovery shows both Lonsdaleite and regular diamond can also form at normal room temperatures by just applying high pressures—equivalent to 640 African elephants on the tip of a ballet shoe.

Lonsdaleite, named after the crystallographer Dame Kathleen Lonsdale, the first woman elected as a Fellow to the Royal Society, has a different crystal structure to regular diamond. It is predicted to be 58% harder.


This is a good signal of an emerging computational paradigm based on the domestication of the nano-scale of matter.
"The scientific holy grail for scaling is going down to a level where a single atom controls the memory function, and this is what we accomplished in the new study,"  

World's smallest atom-memory unit created

Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet. And in the process, they figured out the physics dynamic that unlocks dense memory storage capabilities for these tiny devices.

The research published recently in Nature Nanotechnology builds on a discovery from two years ago, when the researchers created what was then the thinnest memory storage device. In this new work, the researchers reduced the size even further, shrinking the cross section area down to just a single square nanometer.

The race to make smaller chips and components is all about power and convenience. With smaller processors, you can make more compact computers and phones. But shrinking down chips also decreases their energy demands and increases capacity, which means faster, smarter devices that take less power to operate.


A strong signal of the revolution in agriculture, AI, robotics - it’s not just the cities and highways that self-driving vehicles will transform the world.
"This is not about taking away jobs, it's about filling jobs where there currently are no people available to do them. For a while there have been fewer people willing to go out into the fields and harvest fruit and vegetables; this is an autonomous solution to that, and one which is affordable and reliable.

Cutting-edge agricultural robots offers a low-cost lifeline to UK farmers

A low-cost robotic platform which can be fitted with almost any agricultural implement could help farmers across the UK to overcome the lack of available manual labour.

The Robotriks Traction Unit (RTU), created by startup company Robotriks, costs just £7,000—almost a tenth of the cost of most other products on the market.

Powered by batteries which last for 24 hours, it can be built within a few hours and made available for a range of tasks from crop monitoring to harvesting crops like cauliflowers.

Robotriks was co-founded by Jake Shaw-Sutton, Senior Robotics Technician at the University of Plymouth, and Khaian Marsh and is based near St Austell in Cornwall.
