DENVER, Dec. 30 (Reuters) – Colorado Governor Jared Polis on Thursday commuted the 110-year sentence for a truck driver convicted of driving homicide, reducing the jail term to 10 years after prosecutors returned to court this week in a rare move asking for leniency.

In a switching letter to Cuban-born trucker Rogel Lazaro Aguilera-Mederos, 26, the governor said the fiery crash along a mountain highway that killed four motorists in April 2019 was a ” tragic but unintentional act “.

“While you are not blameless, your sentence is disproportionate to many other inmates in our criminal justice system who have committed intentional, premeditated or violent crimes,” the letter reads.

Aguilera-Mederos will now be eligible for parole in five years, the governor said.

Aguilera-Mederos lawyer James Colgan said his client was happy with the news. “He’s relieved and very grateful,” Colgan said.

A message left with District Attorney Alexis King was not immediately returned.

King went to court on Monday for a hearing asking that the 110-year sentence, imposed earlier this month, be reduced to a prison term of 20 to 30 years, arguing that greater leniency was warranted in a high profile case. that prosecutors said there was no criminal intent.

Technology is expected to play an important role in enabling surgeons to perform complex operations.

Muscat: An Omani medical team from Al Khoud Armed Forces Hospital successfully performed a spinal stabilization operation using augmented reality technology on a 52-year-old citizen.

The Defense Ministry said: “The operation was carried out by a medical team led by Colonel Doctor Ahmed Al Jahuri, senior consultant and head of the orthopedics department of the Armed Forces hospital, and medical staff from the armed forces. orthopedics, anesthesia, operations, radiology and medical engineering departments.

Speaking of the surgery which used advanced technology, Dr Al Jahuri said, “The Armed Forces Hospital was able to use advanced augmented reality technology as a solution for the development of minimally invasive spine surgeries.

Dr Al Jahuri added, “In this technique, low dose 3D CT scans are combined with optical imaging with stationary cameras, resulting in the creation of a three-dimensional augmented reality display of the patient’s internal anatomy. , and this combined image acts as an exploration device that guides the surgeon in fixing the vertebrae with surgical screws in place.

“This helps us to conduct a precisely defined surgery and reduces the risk of injury to nearby sensitive tissues such as nerves and blood vessels,” he continued. “” Following this approach leads to increased clinical precision because the surgeon can be sure that the surgical instruments are in the right place before the operation and this helps the physician to reduce surgical risks, medical errors, pain and loss of blood, which leads to a patient recovery and reduced hospitalization, as well as medical complications and subsequent costs.

Technology is expected to play an important role in enabling surgeons to perform complex operations, especially in the area of ​​curvature of the spine. With the ability to tailor augmented reality to the surgeon’s needs, physicians can focus on what is happening right in front of them.

The technology also gives surgeons direct X-ray vision in anatomical areas that are not visible to the naked eye, making this new technology a mainstay of the future of surgery.

Ali bin Hamdan Al Ghafri, the patient who underwent the operation, said: “I suffered from pain in my spine, and after continuous examination at the armed forces hospital and necessary medical examinations, the results showed friction in some vertebrae in the spine. , and it was decided to perform surgery using augmented reality technology.

“I was informed of the details and steps of this procedure by the doctors involved in the operation, and what encouraged me to agree to perform the procedure was the presence of a reputable Omani medical team and efficiency, as well as what the Army Forces Hospital has in terms of modern advanced devices in the field of spinal surgery.

Praising the team who provided him with medical care, Al Ghafri also thanked His Majesty Sultan Haitham Bin Tarik for the attention given to the people of Oman.

Hanan bint Saif, who oversees the operating rooms at the hospital, said: “Spine operations are complex procedures that require the surgeon to be careful when treating the nerves and vessels connected to the spinal cord. spinal.

“Augmented reality technology is one of the latest technologies in spine surgery,” she added. “Around the world, many doctors have been able to perform this surgery using this technique. “

The dream of autonomous robots that can help with household chores, drive us and replace factory workers has been around longer than the Jetsons series released in the 1960s. The reality is that many companies have promised the availability of self-driving cars. ‘by 2020, but we are still waiting. And the situation is not too different in the field of service robotics and industrial automation.

Why is it taking so long?

A key aspect is the way machines perceive their environment. While robotic vision has come a long way over the past decade, thanks in part to higher resolution cameras and newer 3D vision technologies, it is still far less efficient than humans at perceiving its surroundings.

In fact, current approaches could have it all wrong from the start. For example, we humans don’t scan our surroundings with multi-megapixel resolution, then meticulously try to find the outlines of objects and compare them frame by frame to conclude their movement paths.

Imagine sifting through a multi-megapixel image with a magnifying glass, marking slight variations in contrast and color as possible objects, then doing this at ten frames per second to track and predict the movement of objects. hypothetical.

Human perception works differently. Our eye is an extension of our brain, preprocessing large amounts of information. As a result, we have many more motion sensitive cells in our retina, which immediately lets us know if anything is moving in our field of view. Only then do we use our high-resolution cells in the macula to identify objects of interest, a much more efficient way of recognizing, tracking, and predicting objects.

Step into new 3D vision technology available now to help machines perceive their environment much more like humans. This is called a cohesive vision.

The technology sends out coherent laser light and captures much more than information about the intensity of the returned photons. It also captures tiny frequency shifts induced by object movements and provides information about the material and surfaces detected via changes in polarization.

Existing 3D sensing technologies include direct and indirect time-of-flight approaches, projected IR models (aka structured light), and triangulation techniques such as stereo vision. Not all of them offer instantaneous motion information and typically suffer from significant tradeoffs in range, eye safety, crosstalk immunity, and accuracy.

Continuous frequency modulated wave (FMCW) or coherent 3D detection

This diagram illustrates the principle of 3D FMCW detection. A low-power transmit beep (green) is reflected from an object. The frequency offset between the return chirp (blue) is proportional to the distance and speed of the object. A high and low chirp are used to resolve the two values, distance and speed.

Rather than relying on the detection of variations in light intensity, a common method of existing 3D detection techniques, the coherent 3D detection approach relies on the low-power frequency chirps of a highly coherent laser. This is also known as Continuous Frequency Modulated Wave (FMCW) technique, already used in advanced radar sensors.

Coherent photons can travel hundreds of feet, interacting and picking up characteristics of the target, then coming back while remaining in a coherent state where they can be mixed with some of the outgoing light for near lossless amplification.

The back mixing with the outgoing photons results in a beat frequency which is downconverted from the optical frequency, i.e. in the terahertz region, to the low gigahertz region and can be easily analyzed by them. electronic circuits available.

The distance of the measurement results in an optical frequency shift. If the measurement point also has radial velocity, the reflected chirp adds a Doppler frequency shift.

Using a high and low chirp allows coherent 3D sensors to instantly resolve both the range and speed of each pixel. This capability effectively extends 3D detection to 4D, i.e. simultaneous detection of x, y, z and speed vectors of an object.

The mixing of the returned photons with some of the outgoing laser light results in almost lossless optical amplification, allowing much higher sensitivity and detection accuracy. Due to the higher detection sensitivity of coherent systems, a laser power level of the order of one hundred milliwatts is usually sufficient to measure objects hundreds of meters away, allowing this technology to be integrated on a chip for use in mobile applications.

Linearly polarized photons can further change their state of polarization when interacting with targets, allowing the detection of material and surface features, such as windows or human skin.

FMCW advantages and 4D machine vision

Advances in technology and cost reduction have made 3D vision an essential technology in industrial manufacturing automation used to improve productivity, efficiency and quality. With many competing technologies available, the choice of technology is often decided by applications, ranging from general quality inspections, validations, audits and screening to safety and security.

FMCW promises to improve the performance vectors in multiple dimensions, allowing more precise scanning at longer distances while being safe to the eye and safe from outdoor lighting conditions or multi-system crosstalk. On top of that, it offers native 4D vision by providing speed information with every measurement.

What is the hold-up?

Why has it taken so long to generalize coherent 3D detection systems?

The main challenge in creating an FMCW solution has been the low cost, high volume manufacturing of high performance components. The coherent approach requires lasers with long coherence lengths (narrow line widths) and coherent light processing to extract additional information carried by the photons.

This requires very precise and low noise optical signal processing circuitry to form a coherent receiver. In addition, polarization plays a role here, because a coherent beat will only work for photons of the same polarization. The stability of the wavelength and the linearity of the laser source are essential during the measurement; otherwise, the signal to noise ratio may be greatly degraded.

Creating such a stable, robust and precisely defined optical system with discrete components is very difficult and expensive. In order to solve this problem, SiLC Technologies created a solution that integrates all the necessary optical functionality into a single silicon chip using semiconductor manufacturing processes used to fabricate electronic integrated circuits.

In other words, the same approach behind very complex silicon integrated electronic circuits which already enable very low cost consumer products, can now be deployed to realize very complex optical circuits for photonic applications.

The silicon photonics integration platform integrates high performance components into a single chip using mature semiconductor manufacturing processes, providing a low cost, compact and low power consumption solution. Silicon fabrication also offers affordable, high-volume scaling of complex devices and technologies.

Figure 4 SiLC - Eyeonic vision sensor
SiLC Eyeonic The vision sensor based on silicon photonic integrated circuits combines the critical components needed to realize an FMCW LiDAR transceiver in a small form factor.

In summary, 3D vision is essential for the perception of the machine. Coherent 3D sensing using the FMCW technique is the most recent of these technologies, extending the performance characteristics of vision systems to many levels, even in the fourth dimension. Rather than relying on time of flight, stereo vision, triangulation, or structured light, FMCW detection takes advantage of the properties of the photons themselves.

Exploitation of this approach was hampered by the cost and required number of components. The power of silicon integration and the legacy of bringing silicon photonics to market can be harnessed to finally bring a cost effective coherent vision sensor to market. By using additional instantaneous speed information, it will help machines perceive their surroundings more like humans.

“It has never been a solution to homelessness. “

Those words, spoken by Kate Marshall, Wheeling resident and advocate for the homeless, have sadly never been truer. Evicting people – homeless or not – from their place of residence does not solve the problem of their homeless situation. It does not force them to eventually reassess why they are living on the streets or to seek a different path in their life.

It just moves them elsewhere.

On Wednesday, the last homeless people who lived under an 18th Street viaduct in Wheeling left. The Wheeling Police Department facilitated the closure of the camp after the West Virginia Department of Transportation asked the city to enforce “no entry” signs at the site.

It’s now up to people like Marshall and Wheeling’s Homeless Liaison Melissa Adams to help many of these people put the pieces back together.

“They mourn the loss of their neighborhood and their home. … I think it’s the same as the people of Kentucky are feeling right now, ”Marshall said.

The dissolution of the encampment was essentially a test by fire for Adams. On the job for a few months now, Adams has been working to help facilitate mental health care for some camp residents, and also worked with Youth Services Systems earlier this month to have the Winter Freeze Shelter open early so that people have somewhere warm to sleep.

As we noted earlier, helping the homeless is a complex issue. In this case, however, those who lived at the 18th Street site had, in some cases, been there for more than a year.

This allowed them to experience a semblance of community, with services such as Catholic charities and the Greater Wheeling Soup Kitchen nearby. The state has simply done a bad job of fixing this problem.

Ultimately, this truth remains: those displaced from the encampment will find another underpass or other safe place to go until they are told again to continue. Evicting them from the 18th Street site does not resolve that.

Fresh drinking water can be something people often take for granted, but when it comes to a large African country – whose vast land area covers vast areas that differ greatly in their rainfall and sources of water. water – solutions for a regular supply of drinking water are becoming complex, difficult to implement and expensive.

Drought in Angola

Cunene is located in the southern province of Angola, in West Africa, bordering Namibia and characterized by extensive and arid territories. A prolonged drought in southern Angola has hit that province, affecting some 80 percent of the local population, including animals, who have died in large numbers due to lack of water.

Due to the severe drought the region has endured since 2018, it was recognized as a global disaster area and received national and international priority until in 2019 the President of Angola visited the region to assess and respond to the plight of its inhabitants. residents. The president visited a small village called Ombala yo Mungu, where he assured the locals that he would do his best to give the people and animals who live there a source of clean water.

Following the president’s visit, and on his instructions, the Angolan water ministry contacted a number of international companies to provide an urgent response to the water crisis in the region. Owini, a company of the international Mitrelli Group, rose to the challenge by visiting the village, located hundreds of kilometers from the populated areas. On site, the Mitrelli team conducted a field survey to understand the drinking water problem and develop a plan to provide the most appropriate solution for the village.

Following his initial investigation, Owini realized that there were two issues. First, there is no potable water in or around the area. In fact, there is only saline groundwater well below the surface. In addition, there is no energy available in the electric grid to operate the water supply systems, and the rural location of the region meant that it would be extremely difficult to establish a fuel supply for generators.

Owini carried out numerous water tests in the field, including those from old boreholes from the Portuguese period, finding brackish water below the surface. At this stage, the whole concept of the project has changed from the standard installation of a drinking water supply system to a brackish water desalination system; which posed a complex planning, logistical and economic challenge, in addition to the difficulty of operating and maintaining such a system in a remote and arid region.

Subsequently, Owini decided that a rapid desalination solution was needed, with independent capacity for energy production and storage. The facility should also include the ability to store water for several days in the event of a prolonged malfunction, until a technician can arrive, due to the remoteness of the village from more populated areas.

In addition, remote monitoring and control capabilities should be installed to allow receipt of information about malfunctions – and in many cases also their treatment – without the need to send a technician to the site.

The solution

The envisaged solution is an innovative water desalination system entirely based on solar energy, capable of conserving the energy produced during the day and allowing continuous operation 24 hours a day. It was also installed to provide water for a minimum of three working days, even without pumping, as professional repairs could require a three-day journey from Luanda, the capital of Angola.

The system includes two boreholes to create continuous flow, a container with desalination elements and batteries for energy storage / discharge, and solar panels for all operations. Drinking water is then channeled to an underground reservoir, which is enough to support the population for three days, with an independent pumping station also powered by solar energy.

The reverse osmosis water desalination process, in which the salts are separated from the water (in this case brackish groundwater) by means of a membrane, produces potable water, while the production of solar energy operates the desalination process.

The water is pushed under pressure from the pump to the reservoir, and from there to the drinking water points around the village. Photovoltaic panels absorb energy from the sun during the day, and deep cycle batteries store some of that energy for use during nighttime operation.

By combining desalination and solar energy, it is possible to provide good quality water to the inhabitants of a very remote neighborhood where there is no drinking water, regular electricity supply or sources of water. conventional energy.

In addition, it is possible to track the performance of the system through a remote control system and monitor its operation from Owini’s office in Israel.

Pandemic paralysis

The company faced many challenges – flooding that destroyed access roads, high salinity water, lack of energy sources – but most important of all was the coronavirus pandemic which crippled business international.

During this period, it was difficult to continue the planning and preparation work in the field, to produce the various containers and energy devices in Israel, to move the containers full of equipment from Israel to Angola, or to cross the ‘Angola without first obtaining special travel permits. and the work. Despite these challenges, good planning made it possible to execute the project to the client’s satisfaction.

The project was completed in November 2020 as planned. Drinking water that meets European health standards is now flowing to the village for the benefit of residents and their livestock. Government officials and local media come to visit, admiring the innovation and creativity of the project.

Following the great success of this project, and as a prototype project for remote areas without a source of fresh water, there is a desire to replicate it in other areas in Angola. In addition, Owini is using this project to demonstrate solutions for other countries where there are inhabited areas with extreme climatic characteristics, lack of available energy and scarce water sources.

The success of this village is part of a much larger project in Angola called “Water for All”. As the name suggests, its goal is to provide water and long-term sustainable solutions to global water needs, and to improve the standard of living and health of the local population. WW

by BRIAN NADIG

Putting aside the long-standing practice of the Alderman prerogative, the city council’s zoning committee at its December 14 meeting voted 12-5 in favor of a 297-unit apartment proposal that includes 59 housing units. affordable at 8535 W. Higgins Ave. despite the objections of Alderman Anthony Napolitano (41st), whose neighborhood is the project.

Napolitano told committee members that their authority could then be taken away from them, leaving them and their neighborhood with a zoning development their residents don’t want.

“You and your community no longer have a say,” Napolitano told the committee. “You might be the next person to face it. “

Regarding zoning issues, the council almost always defers the decision to the alderman of the neighborhood where the project would be built, although some have said this unofficial practice has blocked the development of affordable housing in the wealthier neighborhoods. .

The committee in 2018 voted 7-5 against the proposal and earlier this year voted to file a similar proposal for the property until February of next year, but the committee voted to change its decision on the postponement and hold the hearing on its December 14th. Encounter. The number of affordable units has increased from seven in 2018 to 59 in the current proposal.

Several city councilors said the city is experiencing an affordable housing crisis and all communities must contribute to the solution.

“We have very big problems in this city which affect us all,” said Alderman Maria Hadden (49th).

In his comments at the hearing, Napolitano noted how Alderman Harry Osterman (48th) now supported Higgins’ proposal, even though he recently rejected a 20-unit housing proposal with four affordable units in his own neighborhood. . Osterman later responded that he was supporting an 80-unit “all-affordable” project across from this site in his neighborhood.

Another supporter of the project was Alderman Gilbert Villegas (36th), who in 2016 rejected an affordable housing project of 55 units in his neighborhood by Full Circle Communities.

Full Circle is currently building a mixed-income housing project in the 45th arrondissement and an affordable housing project in the 38th arrondissement.

The seven-story apartment complex near Higgins Avenue and Cumberland Avenue would be built on an underused section of the Marriott O’Hare hotel parking lot, next to the CTA Cumberland Blue Line station. According to project lawyer Liz Butler, some of the low-rent, affordable units are said to be aimed at households earning as little as 40% of the region’s median income.

Chicago Housing Commissioner Marisa Novara said the development would help provide affordable housing for employees at nearby O’Hare International Airport, where she says the average salary is around $ 33,000. for many jobs. “We cannot make them travel 2 hours to get there,” she said.

Novara added that the project would not receive any grants from the city, as developer GlenStar would fund the affordable units. The city “cannot subsidize our way out” of the housing crisis, she said.

Novara also said city policy calls for denser developments near transit centers. “We have tripled that decision as a city,” she said.

Napolitano told the committee there were about 7,500 apartments within a “seven by seven block radius” of the development site, with at least 300 units vacant. “It’s a huge amount of apartments in this location,” he said. “Some are listed starting at $ 750 online. “

Napolitano said the region’s public primary school, Dirksen, is “almost already at maximum capacity” despite a recent addition. He added that the families at the school represent “100 different nations”.

“There is immense diversity in this field that not everyone claims to exist,” Napolitano said.

About 2,500 people have signed a petition against the proposal, Napolitano said. The Chicago Federation of Labor and the Metropolitan Planning Council were among the organizations that testified in support of the proposal.

It is expected that the development would house five to 16 school-aged children for public schools, Butler said.

The whole council could approve the project, which has been under construction for at least 4 years, at its meeting on December 15.

December 13, 2021 – In September, Novozymes launched its new 2025 strategy, Unleash growth – fueled by biotechnology, which highlighted three pillars of growth: evolving its core business, developing in high-growth areas of biohealth and of human nutrition and explore new growth opportunities.

Carbon capture is a new area of ​​growth opportunity and Novozymes is now delivering on its promise to explore this segment through a new partnership with Saipem, a cutting-edge technology and engineering platform for complex infrastructure and factories. safe and durable.

Novozymes and Saipem have entered into a collaboration agreement to develop enzymatic carbon capture solutions, a biological and economical alternative to traditional carbon capture. The ambition is to bring advanced enzyme-based carbon capture processes to the market.

– “This collaboration is an important step towards sustainable and innovative solutions to reduce greenhouse gas emissions. As part of our strategy, Novozymes is committed to providing biological solutions that enable a healthier planet and our collaboration with Saipem helps us achieve our ambition to explore new growth opportunities while accelerating the fight against climate change, ”said Amy Byrick, Executive Vice President of Strategy and Business Transformation at Novozymes.
Saipem, which is committed to transitioning the energy sector, has developed enzyme-based carbon capture technology, which the two companies will work together to advance under the deal. Saipem will provide the process and mechanical design and equipment while Novozymes will supply enzymes for Saipem’s customers and further optimize the process through enzyme innovation.

Make it an essential tool that saves energy and costs

Carbon capture and storage technologies can capture over 90% of CO2 emissions from power plants and industrial plants and is considered an indispensable tool for decarbonizing the industrial sector.

While traditional processes rely on amines, enzymatic carbon capture uses carbonates and biological components in the form of enzymes to extract CO2 and does so at lower temperatures. This has the potential to dramatically reduce the use of chemicals and energy in the carbon capture process. At the same time, the use of enzymes instead of amines eliminates the need to clean the wastewater because the enzymes do not leave any waste.

The United Nations Intergovernmental Panel on Climate Change endorses carbon capture as a key solution required to limit climate change. Carbon capture and storage technologies can cover 12% of the greenhouse gas emission reductions needed by 2050 for the energy sector, according to the International Energy Agency (IEA). reach net zero emissions by 2070. Carbon capture capacity is expected to exceed 1 Gt of CO2 by 2030 and increase to 5.6 Gt CO2 by 2050 according to IEA estimates.

  • Facts

  • The enzymatic carbon capture uses a solution of carbonates and the enzyme carbonic anhydrase.

  • Carbonic anhydrase is a naturally occurring enzyme that is active in the human lung and in all living organisms. It is responsible for the conversion between the CO2 and bicarbonate (HCO3) when living organisms breathe

  • Carbonates are present in tap water and, together with calcium and magnesium, determine the hardness of the water

In the middle of his historical book About the origin of species, Darwin had a crisis of faith. In a fit of honesty, he wrote: “Suppose that the eye with all its inimitable devices for adjusting focus at different distances, for admitting different amounts of light, and for correcting spherical and chromatic aberrations, might have been formed by natural selection seems, I confess, absurd in the highest degree. While scientists are still working on the details of the eye’s evolution, we are also still stuck on the question of how intelligence emerges in biology. How can a biological system ever generate consistent, goal-oriented bottom-up behavior when there is no external designer?

In fact, intelligence – a deliberate response to available information, often anticipating the future – is not limited to the minds of certain privileged species. It is distributed throughout biology, at many different spatial and temporal scales. It’s not just smart people, mammals, birds, and cephalopods. Intelligent and determined problem-solving behavior can be found in parts of all living things: individual cells and tissues, individual neurons and neural networks, viruses, ribosomes and RNA fragments, up to and including ‘motor proteins and molecular networks. It can be argued that understanding the origin of intelligence is the central problem in biology, a problem still wide open. In this article, we argue that advances in developmental biology and neuroscience now offer a promising avenue for showing how the architecture of modular systems underlies evolutionary and organic intelligence.

Biologists are trained to focus on the mechanisms of living systems and not on their purpose. As biologists, we are supposed to determine the “how” rather than the “why”, pursuing causation rather than goals. The “why” is not only always present, but it is precisely what motivates the choice of specific “how”, allowing organisms to survive by selecting and exploiting specific mechanisms in an astronomically vast space of possibilities. In the case of the human eye, for example, the optical properties of the lens are only meaningful if they help focus light on the retina. If you don’t ask why the lens is transparent, you will never understand its function no matter how long you study how it becomes transparent.

Indeed, the problem of understanding how intelligence emerges worsens with the “omics” revolution, which generates systematic and quantitative data on genomes, transcriptomes, proteomes and connectomes. Biological systems are dissected into their ultimate complexity, but no magical answer appears at the end of the tunnel. The race for big data does not provide a better explanation of living systems. If anything, that makes it more difficult.

Modern biology faces a lack of fundamental knowledge when trying to explain meaningful and intelligent behavior. How can a system made up of cells and electrical signals generate a well-adjusted body with behaviors and mental states? If cells are not intelligent, how can intelligent behavior emerge from a distributed system made up of them? This fundamental mystery permeates biology. All biological phenomena are, in a sense, “group decisions” because organisms are made up of individual parts – organs, tissues, cells, organelles, molecules. What properties of living systems allow components to work together towards higher level goals?

A common solution emerges in two different fields: developmental biology and neuroscience. The argument takes place in three stages. The first is based on one of the first and best design ideas in natural selection: modularity. Modules are autonomous functional units like apartments in a building. Modules implement local goals which are to some extent self-sustaining and self-monitoring. Modules have basic problem-solving intelligence, and their relative independence from the rest of the system allows them to achieve their goals despite changing conditions. In our example of a building, a family living in an apartment could continue with their normal life and pursue their goals, for example by sending the children to school, regardless of what happens in the other apartments. In the body, for example, organs such as the liver function with a specific low-level function, such as controlling nutrients in the blood, in relative independence from what is going on, say, in the brain.

The second step of the argument is that the modules can be assembled into a hierarchy: Lower level modules combine to form increasingly sophisticated upper level modules, which then become new building blocks for even higher level modules, and so on. In our building, families could belong to a local association, such as a local branch of a political party, whose goals could be to ensure the future well-being of all families in the area. And that party could belong to a parliament, the purpose of which could be to shape the politics of the whole country, and so on. In biology, different organs might belong to the same body of an organism, the purpose of which would be to preserve and reproduce, and different organisms might belong to a community, such as a beehive, whose purpose would be to maintain a stable environment for his members. . Likewise, the metabolic and local signaling goals of cells integrate towards a morphogenetic outcome of complex organ construction and repair. Thus, an increasingly sophisticated intelligence emerges from the hierarchies of modules.

This might seem to solve the problem, except that hierarchical modularity still doesn’t explain how evolution, only changing one item at a time at a lower level, can ever manipulate higher levels. Since upper levels are built with lower levers, wouldn’t you still need to tweak a bunch of things at the same time to change a higher level mod? A third step in our argument addresses this problem: each mod has a few key elements that serve as command buttons or trigger points that activate the mod. This is known as model completion, where activating one part of the system turns on the whole system. In our apartment building, the family would have a central figure, say one of the parents, who would represent the family at meetings and involve them when needed. These trigger points serve to represent the whole module and thus allow these modules to be activated, modified, deactivated or deployed in new circumstances without having to manipulate or recreate all of their parts. Additionally, pattern completion naturally emerges from interconnected element systems with interactions between elements.

In recent years, researchers have found evidence for the completion of patterns in neural circuitry and developmental biology. For example, when Luis Carrillo-Reid and his colleagues at Columbia University studied how mice respond to visual stimuli, they found that by activating as few as two neurons in the middle of a mouse brain, which contains more 100 million neurons,could artificially trigger visual perceptions that led to particular behaviors. These fascinating pattern completion neurons activated small modules of cells that encode visual perceptions, which were interpreted by mice as real objects. Likewise, in work published in 2018, Michael Levin of Tufts University and Christopher Martyniuk of the University of Florida examined data showing how triggering a simple bioelectric pattern in non-neural tissue causes cells to build an eye or other complex organs in new locations, such as a tadpole’s intestine.

The idea of ​​hierarchical modularity to explain biological intelligence has already been explored by economist Herbert Simon, neuroscientist Valentino Braitenberg, computer scientist Marvin Minsky, evolutionary biologists Leo Buss, Richard Dawkins and David Haig, and philosopher Daniel C. Dennett, among others. These recent experiments in developmental biology and neuroscience can now provide a common mechanism for how this might work via key nodes that generate model completion. While there is still a lot to learn about how model completion units work, they could provide a solution to the problem of reusing a mod system without having to change everything. The manipulation of local goal-chasing modules, to make them cooperate at multiple organizational scales in the body, is a powerful driving force. It enables evolution to harness the collective intelligence of cellular networks, using and recombining tricks discovered at the lower level while operating robustly despite noise and uncertainty.

Like a ratchet, evolution can thus effectively climb the ladder of intelligence, from simple molecules to cognition. Hierarchical modularity and model completion can help understand the decision-making of cells and neurons during morphogenesis and brain processes, generating well-adaptive animals and behavior. Studying how collective intelligence is emerging in biology can not only help us better understand the processes and products of evolution and design, but could also be relevant for the design of artificial intelligence systems and, more generally, for engineering and even the social sciences.
