Nature’s missing evolutionary law added in new paper by leading scientists and philosophers

An October 22, 2023 commentary by Rae Hodge for Salon.com introduces the new work with a beautiful lede/lead and more,

A recently published scientific article proposes a sweeping new law of nature, approaching the matter with dry, clinical efficiency that still reads like poetry.

“A pervasive wonder of the natural world is the evolution of varied systems, including stars, minerals, atmospheres, and life,” the scientists write in the Proceedings of the National Academy of Sciences. “Evolving systems are asymmetrical with respect to time; they display temporal increases in diversity, distribution, and/or patterned behavior,” they continue, mounting their case from the shoulders of Charles Darwin, extending it toward all things living and not.

To join the known physics laws of thermodynamics, electromagnetism and Newton’s laws of motion and gravity, the nine scientists and philosophers behind the paper propose their “law of increasing functional information.”

In short, a complex and evolving system — whether that’s a flock of gold finches or a nebula or the English language — will produce ever more diverse and intricately detailed states and configurations of itself.

And here, any writer should find their breath caught in their throat. Any writer would have to pause and marvel.

It’s a rare thing to hear the voice of science singing toward its twin in the humanities. The scientists seem to be searching in their paper for the right words to describe the way the nested trills of a flautist rise through a vaulted cathedral to coalesce into notes themselves not played by human breath. And how, in the very same way, the oil-slick sheen of a June Bug wing may reveal its unseen spectra only against the brief-blooming dogwood in just the right season of sun.

Both intricate configurations of art and matter arise and fade according to their shared characteristic, long-known by students of the humanities: each have been graced with enough time to attend to the necessary affairs of their most enduring pleasures.

If you have the time, do read this October 22, 2023 commentary as Hodge waxes eloquent.

An October 16, 2023 news item on phys.org announces the work in a more prosaic fashion,

A paper published in the Proceedings of the National Academy of Sciences describes “a missing law of nature,” recognizing for the first time an important norm within the natural world’s workings.

In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.

It was authored by a nine-member team— scientists from the Carnegie Institution for Science, the California Institute of Technology (Caltech) and Cornell University, and philosophers from the University of Colorado.

An October 16, 2023 Carnegie Science Earth and Planets Laboratory news release on EurekAlert (there is also a somewhat shorter October 16, 2023 version on the Carnegie Science [Carnegie Institution of Science] website), which originated the news item, provides a lot more detail,

“Macroscopic” laws of nature describe and explain phenomena experienced daily in the natural world. Natural laws related to forces and motion, gravity, electromagnetism, and energy, for example, were described more than 150 years ago. 

The new work presents a modern addition — a macroscopic law recognizing evolution as a common feature of the natural world’s complex systems, which are characterised as follows:

  • They are formed from many different components, such as atoms, molecules, or cells, that can be arranged and rearranged repeatedly
  • Are subject to natural processes that cause countless different arrangements to be formed
  • Only a small fraction of all these configurations survive in a process called “selection for function.”   

Regardless of whether the system is living or nonliving, when a novel configuration works well and function improves, evolution occurs. 

The authors’ “Law of Increasing Functional Information” states that the system will evolve “if many different configurations of the system undergo selection for one or more functions.”

“An important component of this proposed natural law is the idea of ‘selection for function,’” says Carnegie astrobiologist Dr. Michael L. Wong, first author of the study.

In the case of biology, Darwin equated function primarily with survival—the ability to live long enough to produce fertile offspring. 

The new study expands that perspective, noting that at least three kinds of function occur in nature. 

The most basic function is stability – stable arrangements of atoms or molecules are selected to continue. Also chosen to persist are dynamic systems with ongoing supplies of energy. 

The third and most interesting function is “novelty”—the tendency of evolving systems to explore new configurations that sometimes lead to startling new behaviors or characteristics. 

Life’s evolutionary history is rich with novelties—photosynthesis evolved when single cells learned to harness light energy, multicellular life evolved when cells learned to cooperate, and species evolved thanks to advantageous new behaviors such as swimming, walking, flying, and thinking. 

The same sort of evolution happens in the mineral kingdom. The earliest minerals represent particularly stable arrangements of atoms. Those primordial minerals provided foundations for the next generations of minerals, which participated in life’s origins. The evolution of life and minerals are intertwined, as life uses minerals for shells, teeth, and bones.

Indeed, Earth’s minerals, which began with about 20 at the dawn of our Solar System, now number almost 6,000 known today thanks to ever more complex physical, chemical, and ultimately biological processes over 4.5 billion years. 

In the case of stars, the paper notes that just two major elements – hydrogen and helium – formed the first stars shortly after the big bang. Those earliest stars used hydrogen and helium to make about 20 heavier chemical elements. And the next generation of stars built on that diversity to produce almost 100 more elements.

“Charles Darwin eloquently articulated the way plants and animals evolve by natural selection, with many variations and traits of individuals and many different configurations,” says co-author Robert M. Hazen of Carnegie Science, a leader of the research.

“We contend that Darwinian theory is just a very special, very important case within a far larger natural phenomenon. The notion that selection for function drives evolution applies equally to stars, atoms, minerals, and many other conceptually equivalent situations where many configurations are subjected to selective pressure.”

The co-authors themselves represent a unique multi-disciplinary configuration: three philosophers of science, two astrobiologists, a data scientist, a mineralogist, and a theoretical physicist.

Says Dr. Wong: “In this new paper, we consider evolution in the broadest sense—change over time—which subsumes Darwinian evolution based upon the particulars of ‘descent with modification.’”  

“The universe generates novel combinations of atoms, molecules, cells, etc. Those combinations that are stable and can go on to engender even more novelty will continue to evolve. This is what makes life the most striking example of evolution, but evolution is everywhere.”

Among many implications, the paper offers: 

  1. Understanding into how differing systems possess varying degrees to which they can continue to evolve. “Potential complexity” or “future complexity” have been proposed as metrics of how much more complex an evolving system might become
  2. Insights into how the rate of evolution of some systems can be influenced artificially. The notion of functional information suggests that the rate of evolution in a system might be increased in at least three ways: (1) by increasing the number and/or diversity of interacting agents, (2) by increasing the number of different configurations of the system; and/or 3) by enhancing the selective pressure on the system (for example, in chemical systems by more frequent cycles of heating/cooling or wetting/drying).
  3. A deeper understanding of generative forces behind the creation and existence of complex phenomena in the universe, and the role of information in describing them
  4. An understanding of life in the context of other complex evolving systems. Life shares certain conceptual equivalencies with other complex evolving systems, but the authors point to a future research direction, asking if there is something distinct about how life processes information on functionality (see also https://royalsocietypublishing.org/doi/10.1098/rsif.2022.0810).
  5. Aiding the search for life elsewhere: if there is a demarcation between life and non-life that has to do with selection for function, can we identify the “rules of life” that allow us to discriminate that biotic dividing line in astrobiological investigations? (See also https://conta.cc/3LwLRYS, “Did Life Exist on Mars? Other Planets? With AI’s Help, We May Know Soon”)
  6. At a time when evolving AI systems are an increasing concern, a predictive law of information that characterizes how both natural and symbolic systems evolve is especially welcome

Laws of nature – motion, gravity, electromagnetism, thermodynamics – etc. codify the general behavior of various macroscopic natural systems across space and time. 

The “law of increasing functional information” published today complements the 2nd law of thermodynamics, which states that the entropy (disorder) of an isolated system increases over time (and heat always flows from hotter to colder objects).

Comments

“This is a superb, bold, broad, and transformational article.  …  The authors are approaching the fundamental issue of the increase in complexity of the evolving universe. The purpose is a search for a ‘missing law’ that is consistent with the known laws.

“At this stage of the development of these ideas, rather like the early concepts in the mid-19th century of coming to understand ‘energy’ and ‘entropy,’ open broad discussion is now essential.”

“The study of Wong et al. is like a breeze of fresh air blowing over the difficult terrain at the trijunction of astrobiology, systems science and evolutionary theory. It follows in the steps of giants such as Erwin Schrödinger, Ilya Prigogine, Freeman Dyson and James Lovelock. In particular, it was Schrödinger who formulated the perennial puzzle: how can complexity increase — and drastically so! — in living systems, while they remain bound by the Second Law of thermodynamics? In the pile of attempts to resolve this conundrum in the course of the last 80 years, Wong et al. offer perhaps the best shot so far.”

“Their central idea, the formulation of the law of increasing functional information, is simple but subtle: a system will manifest an increase in functional information if its various configurations generated in time are selected for one or more functions. This, the authors claim, is the controversial ‘missing law’ of complexity, and they provide a bunch of excellent examples. From my admittedly quite subjective point of view, the most interesting ones pertain to life in radically different habitats like Titan or to evolutionary trajectories characterized by multiple exaptations of traits resulting in a dramatic increase in complexity. Does the correct answer to Schrödinger’s question lie in this direction? Only time will tell, but both my head and my gut are curiously positive on that one. Finally, another great merit of this study is worth pointing out: in this day and age of rabid Counter-Enlightenment on the loose, as well as relentless attacks on the freedom of thought and speech, we certainly need more unabashedly multidisciplinary and multicultural projects like this one.”

The natural laws we recognize today cannot yet account for one astounding characteristic of our universe—the propensity of natural systems to “evolve.” As the authors of this study attest, the tendency to increase in complexity and function through time is not specific to biology, but is a fundamental property observed throughout the universe. Wong and colleagues have distilled a set of principles which provide a foundation for cross-disciplinary discourse on evolving systems. In so doing, their work will facilitate the study of self-organization and emergent complexity in the natural world.

The paper “On the roles of function and selection in evolving systems” provides an innovative, compelling, and sound theoretical framework for the evolution of complex systems, encompassing both living and non-living systems. Pivotal in this new law is functional information, which quantitatively captures the possibilities a system has to perform a function. As some functions are indeed crucial for the survival of a living organism, this theory addresses the core of evolution and is open to quantitative assessment. I believe this contribution has also the merit of speaking to different scientific communities that might find a common ground for open and fruitful discussions on complexity and evolution.

Synthetic human embryos—what now? (1 of 2)

Usually, there’s a rough chronological order to how I introduce the research, but this time I’m looking at the term used to describe it, following up with the various news releases and commentaries about the research, and finishing with a Canadian perspective.

After writing this post (but before it was published), the Weizmann Institute of Science (Israel) made their September 6, 2023 announcement and things changed a bit. That’s in Part two.

Say what you really mean (a terminology issue)

First, it might be useful to investigate the term, ‘synthetic human embryos’ as Julian Hitchcock does in his June 29, 2023 article on Bristows website (h/t Mondaq’s July 5, 2023 news item), Note: Links have been removed,

Synthetic Embryos” are neither Synthetic nor Embryos. So why are editors giving that name to stem cell-based models of human development?

One of the less convincing aspects of the last fortnight’s flurry of announcements about advances in simulating early human development (see here) concerned their name. Headlines galore (in newspapers and scientific journals) referred to “synthetic embryos“.

But embryo models, however impressive, are not embryos. To claim that the fundamental stages of embryo development that we learnt at school – fertilisation, cleavage and compaction – could now be bypassed to achieve the same result would be wrong. Nor are these objects “synthesised”: indeed, their interest to us lies in the ways in which they organise themselves. The researchers merely place the stem cells in a matrix in appropriate conditions, then stand back and watch them do it. Scientists were therefore unhappy about this use of the term in news media, and relieved when the International Society for Stem Cell Research (ISSCR) stepped in with a press release:

“Unlike some recent media reports describing this research, the ISSCR advises against using the term “synthetic embryo” to describe embryo models, because it is inaccurate and can create confusion. Integrated embryo models are neither synthetic nor embryos. While these models can replicate aspects of the early-stage development of human embryos, they cannot and will not develop to the equivalent of postnatal stage humans. Further, the ISSCR Guidelines prohibit the transfer of any embryo model to the uterus of a human or an animal.”

Although this was the ISSCR’s first attempt to put that position to the public, it had already made that recommendation to the research community two years previously. Its 2021 Guidelines for Stem Cell Research and Clinical Translation had recommended researchers to “promote accurate, current, balanced, and responsive public representations of stem cell research”. In particular:

“While organoids, chimeras, embryo models, and other stem cell-based models are useful research tools offering possibilities for further scientific progress, limitations on the current state of scientific knowledge and regulatory constraints must be clearly explained in any communications with the public or media. Suggestions that any of the current in vitro models can recapitulate an intact embryo, human sentience or integrated brain function are unfounded overstatements that should be avoided and contradicted with more precise characterizations of current understanding.”

Here’s a little bit about Hitchcock from his Bristows profile page,

  • Diploma Medical School, University of Birmingham (1975-78)
  • LLB, University of Wolverhampton
  • Diploma in Intellectual Property Law & Practice, University of Bristol
  • Qualified 1998

Following an education in medicine at the University of Birmingham and a career as a BBC science producer, Julian has focused on the law and regulation of life science technologies since 1997, practising in England and Australia. He joined Bristows with Alex Denoon in 2018.

Hitchcock’s June 29, 2023 article comments on why this term is being used,

I have a lot of sympathy with the position of the science writers and editors incurring the scientists’ ire. First, why should journalists have known of the ISSCR’s recommendations on the use of the term “synthetic embryo”? A journalist who found Recommendation 4.1 of the ISSCR Guidelines would probably not have found them specific enough to address the point, and the academic introduction containing the missing detail is hard to find. …

My second reason for being sympathetic to the use of the terrible term is that no suitable alternative has been provided, other than in the Stem Cell Reports paper, which recommends the umbrella terms “embryo models” or “stem cell based embryo models”. …

When asked why she had used the term “synthetic embryo”, the journalist I contacted remarked that, “We’re still working out the right language and it’s something we’re discussing and will no doubt evolve along with the science”.

It is absolutely in the public’s interest (and in the interest of science), that scientific research is explained in terms that the public understands. There is, therefore, a need, I think, for the scientific community to supply a name to the media or endure the penalties of misinformation …

In such an intensely competitive field of research, disagreement among researchers, even as to names, is inevitable. In consequence, however, journalists and their audiences are confronted by a slew of terms which may or may not be synonymous or overlapping, with no agreed term [emphasis mine] for the overall class of stem cell based embryo models. We cannot blame them if they make up snappy titles of their own [emphasis mine]. …

The announcement

The earliest date for the announcement at the International Society for Stem Cell Researh meeting that I can find is Hannah Devlin’s June 14, 2023 article in The Guardian newspaper, Note: A link has been removed,

Scientists have created synthetic human embryos using stem cells, in a groundbreaking advance that sidesteps the need for eggs or sperm.

Scientists say these model embryos, which resemble those in the earliest stages of human development, could provide a crucial window on the impact of genetic disorders and the biological causes of recurrent miscarriage.

However, the work also raises serious ethical and legal issues as the lab-grown entities fall outside current legislation in the UK and most other countries.

The structures do not have a beating heart or the beginnings of a brain, but include cells that would typically go on to form the placenta, yolk sac and the embryo itself.

Prof Magdalena Żernicka-Goetz, of the University of Cambridge and the California Institute of Technology, described the work in a plenary address on Wednesday [June 14, 2023] at the International Society for Stem Cell Research’s annual meeting in Boston.

The (UK) Science Media Centre made expert comments available in a June 14, 2023 posting “expert reaction to Guardian reporting news of creation of synthetic embryos using stem cells.”

Two days later, this June 16, 2023 essay by Kathryn MacKay, Senior Lecturer in Bioethics, University of Sydney (Australia), appeared on The Conversation (h/t June 16, 2023 news item on phys.org), Note: Links have been removed,

Researchers have created synthetic human embryos using stem cells, according to media reports. Remarkably, these embryos have reportedly been created from embryonic stem cells, meaning they do not require sperm and ova.

This development, widely described as a breakthrough that could help scientists learn more about human development and genetic disorders, was revealed this week in Boston at the annual meeting of the International Society for Stem Cell Research.

The research, announced by Professor Magdalena Żernicka-Goetz of the University of Cambridge and the California Institute of Technology, has not yet been published in a peer-reviewed journal. But Żernicka-Goetz told the meeting these human-like embryos had been made by reprogramming human embryonic stem cells.

So what does all this mean for science, and what ethical issues does it present?

MacKay goes on to answer her own questions, from the June 16, 2023 essay, Note: A link has been removed,

One of these quandaries arises around whether their creation really gets us away from the use of human embryos.

Robin Lovell-Badge, the head of stem cell biology and developmental genetics at the Francis Crick Institute in London UK, reportedly said that if these human-like embryos can really model human development in the early stages of pregnancy, then we will not have to use human embryos for research.

At the moment, it is unclear if this is the case for two reasons.

First, the embryos were created from human embryonic stem cells, so it seems they do still need human embryos for their creation. Perhaps more light will be shed on this when Żernicka-Goetz’s research is published.

Second, there are questions about the extent to which these human-like embryos really can model human development.

Professor Magdalena Żernicka-Goetz’s research is published

Almost two weeks later the research from the Cambridge team (there are other teams and countries also racing; see Part two for the news from Sept. 6, 2023) was published, from a June 27, 2023 news item on ScienceDaily,

Cambridge scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why and how pregnancies fail.

Published today [Tuesday, June 27, 2023] in the journal Nature, this embryo model is an organised three-dimensional structure derived from pluripotent stem cells that replicate some developmental processes that occur in early human embryos.

Use of such models allows experimental modelling of embryonic development during the second week of pregnancy. They can help researchers gain basic knowledge of the developmental origins of organs and specialised cells such as sperm and eggs, and facilitate understanding of early pregnancy loss.

A June 27, 2023 University of Cambridge press release (also on EurekAlert), which originated the news item, provides more detail about the work,

“Our human embryo-like model, created entirely from human stem cells, gives us access to the developing structure at a stage that is normally hidden from us due to the implantation of the tiny embryo into the mother’s womb,” said Professor Magdalena Zernicka-Goetz in the University of Cambridge’s Department of Physiology, Development and Neuroscience, who led the work.

She added: “This exciting development allows us to manipulate genes to understand their developmental roles in a model system. This will let us test the function of specific factors, which is difficult to do in the natural embryo.”

In natural human development, the second week of development is an important time when the embryo implants into the uterus. This is the time when many pregnancies are lost.

The new advance enables scientists to peer into the mysterious ‘black box’ period of human development – usually following implantation of the embryo in the uterus – to observe processes never directly observed before.

Understanding these early developmental processes holds the potential to reveal some of the causes of human birth defects and diseases, and to develop tests for these in pregnant women.

Until now, the processes could only be observed in animal models, using cells from zebrafish and mice, for example.

Legal restrictions in the UK currently prevent the culture of natural human embryos in the lab beyond day 14 of development: this time limit was set to correspond to the stage where the embryo can no longer form a twin. [emphasis mine]

Until now, scientists have only been able to study this period of human development using donated human embryos. This advance could reduce the need for donated human embryos in research.

Zernicka-Goetz says the while these models can mimic aspects of the development of human embryos, they cannot and will not develop to the equivalent of postnatal stage humans.

Over the past decade, Zernicka-Goetz’s group in Cambridge has been studying the earliest stages of pregnancy, in order to understand why some pregnancies fail and some succeed.

In 2021 and then in 2022 her team announced in Developmental Cell, Nature and Cell Stem Cell journals that they had finally created model embryos from mouse stem cells that can develop to form a brain-like structure, a beating heart, and the foundations of all other organs of the body.

The new models derived from human stem cells do not have a brain or beating heart, but they include cells that would typically go on to form the embryo, placenta and yolk sac, and develop to form the precursors of germ cells (that will form sperm and eggs).

Many pregnancies fail at the point when these three types of cells orchestrate implantation into the uterus begin to send mechanical and chemical signals to each other, which tell the embryo how to develop properly.

There are clear regulations governing stem cell-based models of human embryos and all researchers doing embryo modelling work must first be approved by ethics committees. Journals require proof of this ethics review before they accept scientific papers for publication. Zernicka-Goetz’s laboratory holds these approvals.

“It is against the law and FDA regulations to transfer any embryo-like models into a woman for reproductive aims. These are highly manipulated human cells and their attempted reproductive use would be extremely dangerous,” said Dr Insoo Hyun, Director of the Center for Life Sciences and Public Learning at Boston’s Museum of Science and a member of Harvard Medical School’s Center for Bioethics.

Zernicka-Goetz also holds position at the California Institute of Technology and is NOMIS Distinguished Scientist and Scholar Awardee.

The research was funded by the Wellcome Trust and Open Philanthropy.

Legal concerns and a Canadian focus

A July 25, 2023 essay by Françoise Baylis and Jocelyn Downie of Dalhousie University (Nova Scotia, Canada) for The Conversation (h/t July 25, 2023 article on phys.org) covers the advantages of doing this work before launching into a discussion of legislation and limits in the UK and, more extensively, in Canada, Note: Links have been removed,

This research could increase our understanding of human development and genetic disorders, help us learn how to prevent early miscarriages, lead to improvements in fertility treatment, and — perhaps — eventually allow for reproduction without using sperm and eggs.

Synthetic human embryos — also called embryoid bodies, embryo-like structures or embryo models — mimic the development of “natural human embryos,” those created by fertilization. Synthetic human embryos include the “cells that would typically go on to form the embryo, placenta and yolk sac, and develop to form the precursors of germ cells (that will form sperm and eggs).”

Though research involving natural human embryos is legal in many jurisdictions, it remains controversial. For some people, research involving synthetic human embryos is less controversial because these embryos cannot “develop to the equivalent of postnatal stage humans.” In other words, these embryos are non-viable and cannot result in live births.

Now, for a closer look at the legalities in the UK and in Canada, from the July 25, 2023 essay, Note: Links have been removed,

The research presented by Żernicka-Goetz at the ISSCR meeting took place in the United Kingdom. It was conducted in accordance with the Human Fertilization and Embryology Act, 1990, with the approval of the U.K. Stem Cell Bank Steering Committee.

U.K. law limits the research use of human embryos to 14 days of development. An embryo is defined as “a live human embryo where fertilisation is complete, and references to an embryo include an egg in the process of fertilisation.”

Synthetic embryos are not created by fertilization and therefore, by definition, the 14-day limit on human embryo research does not apply to them. This means that synthetic human embryo research beyond 14 days can proceed in the U.K.

The door to the touted potential benefits — and ethical controversies — seems wide open in the U.K.

While the law in the U.K. does not apply to synthetic human embryos, the law in Canada clearly does. This is because the legal definition of an embryo in Canada is not limited to embryos created by fertilization [emphasis mine].

The Assisted Human Reproduction Act (the AHR Act) defines an embryo as “a human organism during the first 56 days of its development following fertilization or creation, excluding any time during which its development has been suspended.”

Based on this definition, the AHR Act applies to embryos created by reprogramming human embryonic stem cells — in other words, synthetic human embryos — provided such embryos qualify as human organisms.

A synthetic human embryo is a human organism. It is of the species Homo sapiens, and is thus human. It also qualifies as an organism — a life form — alongside other organisms created by means of fertilization, asexual reproduction, parthenogenesis or cloning.

Given that the AHR Act applies to synthetic human embryos, there are legal limits on their creation and use in Canada.

First, human embryos — including synthetic human embryos – can only be created for the purposes of “creating a human being, improving or providing instruction in assisted reproduction procedures.”

Given the state of the science, it follows that synthetic human embryos could legally be created for the purpose of improving assisted reproduction procedures.

Second, “spare” or “excess” human embryos — including synthetic human embryos — originally created for one of the permitted purposes, but no longer wanted for this purpose, can be used for research. This research must be done in accordance with the consent regulations which specify that consent must be for a “specific research project.”

Finally, all research involving human embryos — including synthetic human embryos — is subject to the 14-day rule. The law stipulates that: “No person shall knowingly… maintain an embryo outside the body of a female person after the fourteenth day of its development following fertilization or creation, excluding any time during which its development has been suspended.”

Putting this all together, the creation of synthetic embryos for improving assisted human reproduction procedures is permitted, as is research using “spare” or “excess” synthetic embryos originally created for this purpose — provided there is specific consent and the research does not exceed 14 days.

This means that while synthetic human embryos may be useful for limited research on pre-implantation embryo development, they are not available in Canada for research on post-implantation embryo development beyond 14 days.

The authors close with this comment about the prospects for expanding Canada’s14-day limit, from the July 25, 2023 essay,

… any argument will have to overcome the political reality that the federal government is unlikely to open up the Pandora’s box of amending the AHR Act.

It therefore seems likely that synthetic human embryo research will remain limited in Canada for the foreseeable future.

As mentioned, in September 2023 there was a new development. See: Part two.

Philosophy and science in Tokyo, Japan from Dec. 1-2, 2022

I have not seen a more timely and à propos overview for a meeting/conference/congress that this one for Tokyo Forum 2022 (hosted by the University of Tokyo and South Korea’s Chey Institute for Advanced Studies),

Dialogue between Philosophy and Science: In a World Facing War, Pandemic, and Climate Change

In the face of war, a pandemic, and climate change, we cannot repeat the history of the last century, in which our ancestors headed down the road to division, global conflict, and environmental destruction.

How can we live more fully and how do we find a new common understanding about what our society should be? Tokyo Forum 2022 will tackle these questions through a series of in-depth dialogues between philosophy and science. The dialogues will weave together the latest findings and deep contemplation, and explore paths that could lead us to viable answers and solutions.

Philosophy of the 21st century must contribute to the construction of a new universality based on locality and diversity. It should be a universality that is open to co-existing with other non-human elements, such as ecosystems and nature, while severely criticizing the understanding of history that unreflectively identifies anthropocentrism with universality.

Science in the 21st century also needs to dispense with its overarching aura of supremacy and lack of self-criticism. There is a need for scientists to make efforts to demarcate their own limits. This also means reexamining what ethics means for science.

Tokyo Forum 2022 will offer multifaceted dialogues between philosophers, scientists, and scholars from various fields of study on the state and humanity in the 21st century, with a view to imagining and proposing a vision of the society we need.

Here are some details about the hybrid event from a November 4, 2022 University of Tokyo press release on EurekAlert,

The University of Tokyo and South Korea’s Chey Institute for Advanced Studies will host Tokyo Forum 2022 from Dec. 1-2, 2022. Under this year’s theme “Dialogue between Philosophy and Science,” the annual symposium will bring together philosophers, scientists and scholars in various fields from around the world for multifaceted dialogues on humanity and the state in the 21st century, while envisioning the society we need.

The event is free and open to the public, and will be held both on site at Yasuda Auditorium of the University of Tokyo and online via livestream. [emphases mine]

Keynote speakers lined up for the first day of the two-day symposium are former U.N. Secretary-General Ban Ki-moon, University of Chicago President Paul Alivisatos and Mariko Hasegawa, president of the Graduate University for Advanced Studies in Japan.

Other featured speakers on the event’s opening day include renowned modern thinker and author Professor Markus Gabriel of the University of Bonn, and physicist Hirosi Ooguri, director of the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo and professor at the California Institute of Technology, who are scheduled to participate in the high-level discussion on the dialogue between philosophy and science.

Columbia University Professor Jeffrey Sachs will take part in a panel discussion, also on Day 1, on tackling global environmental issues with stewardship of the global commons — the stable and resilient Earth system that sustains our lives — as a global common value.

The four panel discussions slated for Day 2 will cover the role of world philosophy in addressing the problems of a globalized world; transformative change for a sustainable future by understanding the diverse values of nature and its contributions to people; the current and future impacts of autonomous robots on society; and finding collective solutions and universal values to pursue equitable and sustainable futures for humanity by looking at interconnections among various fields of inquiry.

Opening remarks will be delivered by University of Tokyo President Teruo Fujii and South Korea’s SK Group Chairman Chey Tae-won, on Day 1. Fujii and Chey Institute President Park In-kook will make closing remarks following the wrap-up session on the second and final day.

Tokyo Forum with its overarching theme “Shaping the Future” is held annually since 2019 to stimulate discussions on finding the best ideas for shaping the world and humanity in the face of complex situations where the conventional wisdom can no longer provide answers.

Quantum Mechanics & Gravity conference (August 15 – 19, 2022) launches Vancouver (Canada)-based Quantum Gravity Institute and more

I received (via email) a July 21, 2022 news release about the launch of a quantum science initiative in Vancouver (BTW, I have more about the Canadian quantum scene later in this post),

World’s top physicists unite to tackle one of Science’s greatest
mysteries


Vancouver-based Quantum Gravity Society leads international quest to
discover Theory of Quantum Gravity

Vancouver, B.C. (July 21, 2022): More than two dozen of the world’s
top physicists, including three Nobel Prize winners, will gather in
Vancouver this August for a Quantum Gravity Conference that will host
the launch a Vancouver-based Quantum Gravity Institute (QGI) and a
new global research collaboration that could significantly advance our
understanding of physics and gravity and profoundly change the world as
we know it.

For roughly 100 years, the world’s understanding of physics has been
based on Albert Einstein’s General Theory of Relativity (GR), which
explored the theory of space, time and gravity, and quantum mechanics
(QM), which focuses on the behaviour of matter and light on the atomic
and subatomic scale. GR has given us a deep understanding of the cosmos,
leading to space travel and technology like atomic clocks, which govern
global GPS systems. QM is responsible for most of the equipment that
runs our world today, including the electronics, lasers, computers, cell
phones, plastics, and other technologies that support modern
transportation, communications, medicine, agriculture, energy systems
and more.

While each theory has led to countless scientific breakthroughs, in many
cases, they are incompatible and seemingly contradictory. Discovering a
unifying connection between these two fundamental theories, the elusive
Theory of Quantum Gravity, could provide the world with a deeper
understanding of time, gravity and matter and how to potentially control
them. It could also lead to new technologies that would affect most
aspects of daily life, including how we communicate, grow food, deliver
health care, transport people and goods, and produce energy.

“Discovering the Theory of Quantum Gravity could lead to the
possibility of time travel, new quantum devices, or even massive new
energy resources that produce clean energy and help us address climate
change,” said Philip Stamp, Professor, Department of Physics and
Astronomy, University of British Columbia, and Visiting Associate in
Theoretical Astrophysics at Caltech [California Institute of Technology]. “The potential long-term ramifications of this discovery are so incredible that life on earth 100
years from now could look as miraculous to us now as today’s
technology would have seemed to people living 100 years ago.”

The new Quantum Gravity Institute and the conference were founded by the
Quantum Gravity Society, which was created in 2022 by a group of
Canadian technology, business and community leaders, and leading
physicists. Among its goals are to advance the science of physics and
facilitate research on the Theory of Quantum Gravity through initiatives
such as the conference and assembling the world’s leading archive of
scientific papers and lectures associated with the attempts to reconcile
these two theories over the past century.

Attending the Quantum Gravity Conference in Vancouver (August 15-19 [2022])
will be two dozen of the world’s top physicists, including Nobel
Laureates Kip Thorne, Jim Peebles and Sir Roger Penrose, as well as
physicists Baron Martin Rees, Markus Aspelmeyer, Viatcheslav Mukhanov
and Paul Steinhardt. On Wednesday, August 17, the conference will be
open to the public, providing them with a once-in-a-lifetime opportunity
to attend keynote addresses from the world’s pre-eminent physicists.
… A noon-hour discussion on the importance of the
research will be delivered by Kip Thorne, the former Feynman Professor
of physics at Caltech. Thorne is well known for his popular books, and
for developing the original idea for the 2014 film “Interstellar.” He
was also crucial to the development of the book “Contact” by Carl Sagan,
which was also made into a motion picture.

“We look forward to welcoming many of the world’s brightest minds to
Vancouver for our first Quantum Gravity Conference,” said Frank
Giustra, CEO Fiore Group and Co-Founder, Quantum Gravity Society. “One
of the goals of our Society will be to establish Vancouver as a
supportive home base for research and facilitate the scientific
collaboration that will be required to unlock this mystery that has
eluded some of the world’s most brilliant physicists for so long.”

“The format is key,” explains Terry Hui, UC Berkley Physics alumnus
and Co-Founder, Quantum Gravity Society [and CEO of Concord Pacific].
“Like the Solvay Conference nearly 100 years ago, the Quantum Gravity
Conference will bring top scientists together in salon-style gatherings. The
relaxed evening format following the conference will reduce barriers and
allow these great minds to freely exchange ideas. I hope this will help accelerate
the solution of this hundred-year bottleneck between theories relatively
soon.”

“As amazing as our journey of scientific discovery has been over the
past century, we still have so much to learn about how the universe
works on a macro, atomic and subatomic level,” added Paul Lee,
Managing Partner, Vanedge Capital, and Co-Founder, Quantum Gravity
Society. “New experiments and observations capable of advancing work
on this scientific challenge are becoming increasingly possible in
today’s physics labs and using new astronomical tools. The Quantum
Gravity Society looks forward to leveraging that growing technical
capacity with joint theory and experimental work that harnesses the
collective expertise of the world’s great physicists.”

About Quantum Gravity Society

Given that Kip Thorne won his 2017 Nobel Prize in Physics (with Rainer Weiss and Barry Barish) for work on gravitational waves, it’s surprising there’s no mention of this in the publicity for a conference on quantum gravity. Finding gravitational waves in 2016 was a very big deal (see Josh Fischman’s and Steve Mirsky’s February 11, 2016 interview with Kip Thorne for Scientific American).

Some thoughts on this conference and the Canadian quantum scene

This conference has a fascinating collection of players. Even I recognized some of the names, e.g., Penrose, Rees, Thorne.

The academics were to be expected and every presenter is an academic, often with their own Wikipedia page. Weirdly, there’s no one from the Perimeter Institute Institute for Theoretical Physics or TRIUMF (a national physics laboratory and centre for particle acceleration) or from anywhere else in Canada, which may be due to their academic specialty rather than an attempt to freeze out Canadian physicists. In any event, the conference academics are largely from the US (a lot of them from CalTech and Stanford) and from the UK.

The business people are a bit of a surprise. The BC Business Council and the Greater Vancouver Board of Trade? Frank Giustra who first made his money with gold mines, then with Lionsgate Entertainment, and who continues to make a great deal of money with his equity investment company, Fiore Group? Terry Hui, Chief Executive Office of Concord Pacific, a real estate development company? VanEdge Capital, an early stage venture capital fund? A winery? Missing from this list is D-Wave Systems, Canada’s quantum calling card and local company. While their area of expertise is quantum computing, I’d still expect to see them present as sponsors. *ETA December 6, 2022: I just looked at the conference page again and D-Wave is now listed as a sponsor.*

The academics? These people are not cheap dates (flights, speaker’s fees, a room at the Bayshore, meals). This is a very expensive conference and $129 for lunch and a daypass is likely a heavily subsidized ticket.

Another surprise? No government money/sponsorship. I don’t recall seeing another academic conference held in Canada without any government participation.

Canadian quantum scene

A National Quantum Strategy was first announced in the 2021 Canadian federal budget and reannounced in the 2022 federal budget (see my April 19, 2022 posting for a few more budget details).. Or, you may find this National Quantum Strategy Consultations: What We Heard Report more informative. There’s also a webpage for general information about the National Quantum Strategy.

As evidence of action, the Natural Science and Engineering Research Council of Canada (NSERC) announced new grant programmes made possible by the National Quantum Strategy in a March 15, 2022 news release,

Quantum science and innovation are giving rise to promising advances in communications, computing, materials, sensing, health care, navigation and other key areas. The Government of Canada is committed to helping shape the future of quantum technology by supporting Canada’s quantum sector and establishing leadership in this emerging and transformative domain.

Today [March 15, 2022], the Honourable François-Philippe Champagne, Minister of Innovation, Science and Industry, is announcing an investment of $137.9 million through the Natural Sciences and Engineering Research Council of Canada’s (NSERC) Collaborative Research and Training Experience (CREATE) grants and Alliance grants. These grants are an important next step in advancing the National Quantum Strategy and will reinforce Canada’s research strengths in quantum science while also helping to develop a talent pipeline to support the growth of a strong quantum community.

Quick facts

Budget 2021 committed $360 million to build the foundation for a National Quantum Strategy, enabling the Government of Canada to build on previous investments in the sector to advance the emerging field of quantum technologies. The quantum sector is key to fuelling Canada’s economy, long-term resilience and growth, especially as technologies mature and more sectors harness quantum capabilities.

Development of quantum technologies offers job opportunities in research and science, software and hardware engineering and development, manufacturing, technical support, sales and marketing, business operations and other fields.

The Government of Canada also invested more than $1 billion in quantum research and science from 2009 to 2020—mainly through competitive granting agency programs, including Natural Sciences and Engineering Research Council of Canada programs and the Canada First Research Excellence Fund—to help establish Canada as a global leader in quantum science.

In addition, the government has invested in bringing new quantum technologies to market, including investments through Canada’s regional development agencies, the Strategic Innovation Fund and the National Research Council of Canada’s Industrial Research Assistance Program.

Bank of Canada, cryptocurrency, and quantum computing

My July 25, 2022 posting features a special project, Note: All emphases are mine,

… (from an April 14, 2022 HKA Marketing Communications news release on EurekAlert),

Multiverse Computing, a global leader in quantum computing solutions for the financial industry and beyond with offices in Toronto and Spain, today announced it has completed a proof-of-concept project with the Bank of Canada through which the parties used quantum computing to simulate the adoption of cryptocurrency as a method of payment by non-financial firms.

“We are proud to be a trusted partner of the first G7 central bank to explore modelling of complex networks and cryptocurrencies through the use of quantum computing,” said Sam Mugel, CTO [Chief Technical Officer] at Multiverse Computing. “The results of the simulation are very intriguing and insightful as stakeholders consider further research in the domain. Thanks to the algorithm we developed together with our partners at the Bank of Canada, we have been able to model a complex system reliably and accurately given the current state of quantum computing capabilities.”

Multiverse Computing conducted its innovative work related to applying quantum computing for modelling complex economic interactions in a research project with the Bank of Canada. The project explored quantum computing technology as a way to simulate complex economic behaviour that is otherwise very difficult to simulate using traditional computational techniques.

By implementing this solution using D-Wave’s annealing quantum computer, the simulation was able to tackle financial networks as large as 8-10 players, with up to 2^90 possible network configurations. Note that classical computing approaches cannot solve large networks of practical relevance as a 15-player network requires as many resources as there are atoms in the universe.

Quantum Technologies and the Council of Canadian Academies (CCA)

In a May 26, 2022 blog posting the CCA announced its Expert Panel on Quantum Technologies (they will be issuing a Quantum Technologies report),

The emergence of quantum technologies will impact all sectors of the Canadian economy, presenting significant opportunities but also risks. At the request of the National Research Council of Canada (NRC) and Innovation, Science and Economic Development Canada (ISED), the Council of Canadian Academies (CCA) has formed an Expert Panel to examine the impacts, opportunities, and challenges quantum technologies present for Canadian industry, governments, and Canadians. Raymond Laflamme, O.C., FRSC, Canada Research Chair in Quantum Information and Professor in the Department of Physics and Astronomy at the University of Waterloo, will serve as Chair of the Expert Panel.

“Quantum technologies have the potential to transform computing, sensing, communications, healthcare, navigation and many other areas,” said Dr. Laflamme. “But a close examination of the risks and vulnerabilities of these technologies is critical, and I look forward to undertaking this crucial work with the panel.”

As Chair, Dr. Laflamme will lead a multidisciplinary group with expertise in quantum technologies, economics, innovation, ethics, and legal and regulatory frameworks. The Panel will answer the following question:

In light of current trends affecting the evolution of quantum technologies, what impacts, opportunities and challenges do these present for Canadian industry, governments and Canadians more broadly?

The Expert Panel on Quantum Technologies:

Raymond Laflamme, O.C., FRSC (Chair), Canada Research Chair in Quantum Information; the Mike and Ophelia Lazaridis John von Neumann Chair in Quantum Information; Professor, Department of Physics and Astronomy, University of Waterloo

Sally Daub, Founder and Managing Partner, Pool Global Partners

Shohini Ghose, Professor, Physics and Computer Science, Wilfrid Laurier University; NSERC Chair for Women in Science and Engineering

Paul Gulyas, Senior Innovation Executive, IBM Canada

Mark W. Johnson, Senior Vice-President, Quantum Technologies and Systems Products, D-Wave Systems

Elham Kashefi, Professor of Quantum Computing, School of Informatics, University of Edinburgh; Directeur de recherche au CNRS, LIP6 Sorbonne Université

Mauritz Kop, Fellow and Visiting Scholar, Stanford Law School, Stanford University

Dominic Martin, Professor, Département d’organisation et de ressources humaines, École des sciences de la gestion, Université du Québec à Montréal

Darius Ornston, Associate Professor, Munk School of Global Affairs and Public Policy, University of Toronto

Barry Sanders, FRSC, Director, Institute for Quantum Science and Technology, University of Calgary

Eric Santor, Advisor to the Governor, Bank of Canada

Christian Sarra-Bournet, Quantum Strategy Director and Executive Director, Institut quantique, Université de Sherbrooke

Stephanie Simmons, Associate Professor, Canada Research Chair in Quantum Nanoelectronics, and CIFAR Quantum Information Science Fellow, Department of Physics, Simon Fraser University

Jacqueline Walsh, Instructor; Director, initio Technology & Innovation Law Clinic, Dalhousie University

You’ll note that both the Bank of Canada and D-Wave Systems are represented on this expert panel.

The CCA Quantum Technologies report (in progress) page can be found here.

Does it mean anything?

Since I only skim the top layer of information (disparagingly described as ‘high level’ by the technology types I used to work with), all I can say is there’s a remarkable level of interest from various groups who are self-organizing. (The interest is international as well. I found the International Society for Quantum Gravity [ISQG], which had its first meeting in 2021.)

I don’t know what the purpose is other than it seems the Canadian focus seems to be on money. The board of trade and business council have no interest in primary research and the federal government’s national quantum strategy is part of Innovation, Science and Economic Development (ISED) Canada’s mandate. You’ll notice ‘science’ is sandwiched between ‘innovation’, which is often code for business, and economic development.

The Bank of Canada’s monetary interests are quite obvious.

The Perimeter Institute mentioned earlier was founded by Mike Lazaridis (from his Wikipedia entry) Note: Links have been removed,

… a Canadian businessman [emphasis mine], investor in quantum computing technologies, and founder of BlackBerry, which created and manufactured the BlackBerry wireless handheld device. With an estimated net worth of US$800 million (as of June 2011), Lazaridis was ranked by Forbes as the 17th wealthiest Canadian and 651st in the world.[4]

In 2000, Lazaridis founded and donated more than $170 million to the Perimeter Institute for Theoretical Physics.[11][12] He and his wife Ophelia founded and donated more than $100 million to the Institute for Quantum Computing at the University of Waterloo in 2002.[8]

That Institute for Quantum Computing? There’s an interesting connection. Raymond Laflamme, the chair for the CCA expert panel, was its director for a number of years and he’s closely affiliated with the Perimeter Institute. (I’m not suggesting anything nefarious or dodgy. It’s a small community in Canada and relationships tend to be tightly interlaced.) I’m surprised he’s not part of the quantum mechanics and gravity conference but that could have something to do with scheduling.

One last interesting bit about Laflamme, from his Wikipedia entry, Note: Links have been removed)

As Stephen Hawking’s PhD student, he first became famous for convincing Hawking that time does not reverse in a contracting universe, along with Don Page. Hawking told the story of how this happened in his famous book A Brief History of Time in the chapter The Arrow of Time.[3] Later on Laflamme made a name for himself in quantum computing and quantum information theory, which is what he is famous for today.

Getting back to the Quantum Mechanics & Gravity: Marrying Theory & Experiment, the public day looks pretty interesting and when is the next time you’ll have a chance to hobnob with all those Nobel Laureates?

July 2020 update on Dr. He Jiankui (the CRISPR twins) situation

This was going to be written for January 2020 but sometimes things happen (e.g., a two-part overview of science culture in Canada from 2010-19 morphed into five parts with an addendum and, then, a pandemic). By now (July 28, 2020), Dr. He’s sentencing to three years in jail announced by the Chinese government in January 2020 is old news.

Regardless, it seems a neat and tidy ending to an international scientific scandal concerned with germline-editing which resulted in at least one set of twins, Lulu and Nana. He claimed to have introduced a variant (“Delta 32” variation) of their CCR5 gene. This does occur naturally and scientists have noted that people with this mutation seem to be resistant to HIV and smallpox.

For those not familiar with the events surrounding the announcement, here’s a brief recap. News of the world’s first gene-edited twins’ birth was announced in November 2018 just days before an international meeting group of experts who had agreed on a moratorium in 2015 on exactly that kind of work. The scientist making the announcement about the twins was scheduled for at least one presentation at the meeting, which was to be held in Hong Kong. He did give his presentation but left the meeting shortly afterwards as shock was beginning to abate and fierce criticism was rising. My November 28, 2018 posting (First CRISPR gene-edited babies? Ethics and the science story) offers a timeline of sorts and my initial response.

I subsequently followed up with two mores posts as the story continued to develop. My May 17, 2019 posting (Genes, intelligence, Chinese CRISPR (clustered regularly interspaced short palindromic repeats) babies, and other children) featured news that Dr. He’s gene-editing may have resulted in the twins having improved cognitive skills. Then, more news broke. The title for my June 20, 2019 posting (Greater mortality for the CRISPR twins Lulu and Nana?) is self-explanatory.

I have roughly organized my sources for this posting into two narratives, which I’m contrasting with each other. First, there is one found in the mainstream media (English language), ‘The Popular Narrative’. Second, there is story where Dr. He is viewed more sympathetically and as part of a larger community where there isn’t nearly as much consensus over what should or shouldn’t be done as ‘the popular narrative’ insists.

The popular narrative: Dr. He was a rogue scientist

A December 30, 2019 article for Fast Company by Kristin Toussaint lays out the latest facts (Note: A link has been removed),

… Now, a court in China has sentenced He to three years in prison, according to Xinhua, China’s state-run press agency, for “illegal medical practices.”

The court in China’s southern city of Shenzhen says that He’s team, which included colleagues Zhang Renli and Qin Jinzhou from two medical institutes in Guangdong Province, falsified ethical approval documents and violated China’s “regulations and ethical principles” with their gene-editing work. Zhang was sentenced to two years in jail, and Qin to 18 months with a two-year reprieve, according to Xinhau.

Ian Sample’s December 31, 2020 article for the Guardian offers more detail (Note: Links have been removed),

The court in Shenzhen found He guilty of “illegal medical practices” and in addition to the prison sentence fined him 3m yuan (£327,360), according to the state news agency, Xinhua. Two others on He’s research team received lesser fines and sentences.

“The three accused did not have the proper certification to practise medicine, and in seeking fame and wealth, deliberately violated national regulations in scientific research and medical treatment,” the court said, according to Xinhua. “They’ve crossed the bottom line of ethics in scientific research and medical ethics.”

[…] the court found He had forged documents from an ethics review panel that were used to recruit couples for the research. The couples that enrolled had a man with HIV and a woman without and were offered IVF in return for taking part.

Zhang Renli, who worked with He, was sentenced to two years in prison and fined 1m yuan. Colleague Qin Jinzhou received an 18-month sentence, but with a two-year reprieve, and a 500,000 yuan fine.

He’s experiments, which were carried out on seven embryos in late 2018, sent shockwaves through the medical and scientific world. The work was swiftly condemned for deceiving vulnerable patients and using a risky, untested procedure with no medical justification. Earlier this month, MIT Technology Review released excerpts from an early manuscript of He’s work. It casts serious doubts on his claims to have made the children immune to HIV.

Even as the scientific community turned against He, the scientist defended his work and said he was proud of having created Lulu and Nana. A third child has since been born as a result of the experiments.

Robin Lovell-Badge at the Francis Crick Institute in London said it was “far too premature” for anyone to pursue genome editing on embryos that are intended to lead to pregnancies. “At this stage we do not know if the methods will ever be sufficiently safe and efficient, although the relevant science is progressing rapidly, and new methods can look promising. It is also important to have standards established, including detailed regulatory pathways, and appropriate means of governance.”

A December 30, 2019 article, by Carolyn Y. Johnson for the Washington Post, covers much the same ground although it does go on to suggest that there might be some blame to spread around (Note: Links have been removed),

The Chinese researcher who stunned and alarmed the international scientific community with the announcement that he had created the world’s first gene-edited babies has been sentenced to three years in prison by a court in China.

He Jiankui sparked a bioethical crisis last year when he claimed to have edited the DNA of human embryos, resulting in the birth of twins called Lulu and Nana as well as a possible third pregnancy. The gene editing, which was aimed at making the children immune to HIV, was excoriated by many scientists as a reckless experiment on human subjects that violated basic ethical principles.

The judicial proceedings were not public, and outside experts said it is hard to know what to make of the punishment without the release of the full investigative report or extensive knowledge of Chinese law and the conditions under which He will be incarcerated.

Jennifer Doudna, a biochemist at the University of California at Berkeley who co-invented CRISPR, the gene editing technology that He utilized, has been outspoken in condemning the experiments and has repeatedly said CRISPR is not ready to be used for reproductive purposes.

R. Alta Charo, a fellow at Stanford’s Center for Advanced Study in the Behavioral Sciences, was among a small group of experts who had dinner with He the night before he unveiled his controversial research in Hong Kong in November 2018.

“He Jiankui is an example of somebody who fundamentally didn’t understand, or didn’t want to recognize, what have become international norms around responsible research,” Charo said. “My impression is he allowed his personal ambition to completely cloud rational thinking and judgment.”

Scientists have been testing an array of powerful biotechnology tools to fix genetic diseases in adults. There is tremendous excitement about the possibility of fixing genes that cause serious disease, and the first U.S. patients were treated with CRISPR this year.

But scientists have long drawn a clear moral line between curing genetic diseases in adults and editing and implanting human embryos, which raises the specter of “designer babies.” Those changes and any unanticipated ones could be inherited by future generations — in essence altering the human species.

“The fact that the individual at the center of the story has been punished for his role in it should not distract us from examining what supporting roles were played by others, particularly in the international scientific community and also the environment that shaped and encouraged him to push the limits,” said Benjamin Hurlbut [emphasis mine], associate professor in the School of Life Sciences at Arizona State University.

Stanford University cleared its scientists, including He’s former postdoctoral adviser, Stephen Quake, finding that Quake and others did not participate in the research and had expressed “serious concerns to Dr. He about his work.” A Rice University spokesman said an investigation continues into bioengineering professor Michael Deem, He’s former academic adviser. Deem was listed as a co-author on a paper called “Birth of Twins After Genome Editing for HIV Resistance,” submitted to scientific journals, according to MIT Technology Review.

It’s interesting that it’s only the Chinese scientists who are seen to be punished, symbolically at least. Meanwhile, Stanford clears its scientists of any wrongdoing and Rice University continues to investigate.

Watch for the Hurlbut name (son, Benjamin and father, William) to come up again in the ‘complex narrative’ section.

Criticism of the ‘twins’ CRISPR editing’ research

Antonio Regalado’s December 3, 2020 article for the MIT (Massachusetts Institute of Technology) Technology Review features comments from various experts on an unpublished draft of Dr. He Jiankui’s research

Earlier this year a source sent us a copy of an unpublished manuscript describing the creation of the first gene-edited babies, born last year in China. Today, we are making excerpts of that manuscript public for the first time.

Titled “Birth of Twins After Genome Editing for HIV Resistance,” and 4,699 words long, the still unpublished paper was authored by He Jiankui, the Chinese biophysicist who created the edited twin girls. A second manuscript we also received discusses laboratory research on human and animal embryos.

The metadata in the files we were sent indicate that the two draft papers were edited by He in late November 2018 and appear to be what he initially submitted for publication. Other versions, including a combined manuscript, may also exist. After consideration by at least two prestigious journals, Nature and JAMA, his research remains unpublished.

The text of the twins paper is replete with expansive claims of a medical breakthrough that can “control the HIV epidemic.” It claims “success”—a word used more than once—in using a “novel therapy” to render the girls resistant to HIV. Yet surprisingly, it makes little attempt to prove that the twins really are resistant to the virus. And the text largely ignores data elsewhere in the paper suggesting that the editing went wrong.

We shared the unpublished manuscripts with four experts—a legal scholar, an IVF doctor, an embryologist, and a gene-editing specialist—and asked them for their reactions. Their views were damning. Among them: key claims that He and his team made are not supported by the data; the babies’ parents may have been under pressure to agree to join the experiment; the supposed medical benefits are dubious at best; and the researchers moved forward with creating living human beings before they fully understood the effects of the edits they had made.

1. Why aren’t the doctors among the paper’s authors?

The manuscript begins with a list of the authors—10 of them, mostly from He Jiankui’s lab at the Southern University of Science and Technology, but also including Hua Bai, director of an AIDS support network, who helped recruit couples, and Michael Deem, an American biophysicist whose role is under review by Rice University. (His attorney previously said Deem never agreed to submit the manuscript and sought to remove his name from it.)

It’s a small number of people for such a significant project, and one reason is that some names are missing—notably, the fertility doctors who treated the patients and the obstetrician who delivered the babies. Concealing them may be an attempt to obscure the identities of the patients. However, it also leaves unclear whether or not these doctors understood they were helping to create the first gene-edited babies.

To some, the question of whether the manuscript is trustworthy arises immediately.

Hank Greely, professor of law, Stanford University: We have no, or almost no, independent evidence for anything reported in this paper. Although I believe that the babies probably were DNA-edited and were born, there’s very little evidence for that. Given the circumstances of this case, I am not willing to grant He Jiankui the usual presumption of honesty. 

That last article by Regalado is the purest example I have of how fierce the criticism is and how almost all of it is focused on Dr. He and his Chinese colleagues.

A complex, measured narrative: multiple players in the game

The most sympathetic and, in many ways, the most comprehensive article is an August 1, 2019 piece by Jon Cohen for Science magazine (Note: Links have been removed),

On 10 June 2017, a sunny and hot Saturday in Shenzhen, China, two couples came to the Southern University of Science and Technology (SUSTech) to discuss whether they would participate in a medical experiment that no researcher had ever dared to conduct. The Chinese couples, who were having fertility problems, gathered around a conference table to meet with He Jiankui, a SUSTech biophysicist. Then 33, He (pronounced “HEH”) had a growing reputation in China as a scientist-entrepreneur but was little known outside the country. “We want to tell you some serious things that might be scary,” said He, who was trim from years of playing soccer and wore a gray collared shirt, his cuffs casually unbuttoned.

He simply meant the standard in vitro fertilization (IVF) procedures. But as the discussion progressed, He and his postdoc walked the couples through informed consent forms [emphasis mine] that described what many ethicists and scientists view as a far more frightening proposition. Seventeen months later, the experiment triggered an international controversy, and the worldwide scientific community rejected him. The scandal cost him his university position and the leadership of a biotech company he founded. Commentaries labeled He, who also goes by the nickname JK, a “rogue,” “China’s Frankenstein,” and “stupendously immoral.” [emphases mine]

But that day in the conference room, He’s reputation remained untarnished. As the couples listened and flipped through the forms, occasionally asking questions, two witnesses—one American, the other Chinese—observed [emphasis mine]. Another lab member shot video, which Science has seen [emphasis mine], of part of the 50-minute meeting. He had recruited those couples because the husbands were living with HIV infections kept under control by antiviral drugs. The IVF procedure would use a reliable process called sperm washing to remove the virus before insemination, so father-to-child transmission was not a concern. Rather, He sought couples who had endured HIV-related stigma and discrimination and wanted to spare their children that fate by dramatically reducing their risk of ever becoming infected. [emphasis mine]

He, who for much of his brief career had specialized in sequencing DNA, offered a potential solution: CRISPR, the genome-editing tool that was revolutionizing biology, could alter a gene in IVF embryos to cripple production of an immune cell surface protein, CCR5, that HIV uses to establish an infection. “This technique may be able to produce an IVF baby naturally immunized against AIDS,” one consent form read.[emphasis mine]

The couples’ children could also pass the protective mutation to future generations. The prospect of this irrevocable genetic change is why, since the advent of CRISPR as a genome editor 5 years earlier, the editing of human embryos, eggs, or sperm has been hotly debated. The core issue is whether such germline editing would cross an ethical red line because it could ultimately alter our species. Regulations, some with squishy language, arguably prohibited it in many countries, China included.

Yet opposition was not unanimous. A few months before He met the couples, a committee convened by the U.S. National Academies of Sciences, Engineering, and Medicine (NASEM) concluded in a well-publicized report that human trials of germline editing “might be permitted” if strict criteria were met. The group of scientists, lawyers, bioethicists, and patient advocates spelled out a regulatory framework but cautioned that “these criteria are necessarily vague” because various societies, caregivers, and patients would view them differently. The committee notably did not call for an international ban, arguing instead for governmental regulation as each country deemed appropriate and “voluntary self-regulation pursuant to professional guidelines.”

[…] He hid his plans and deceived his colleagues and superiors, as many people have asserted? A preliminary investigation in China stated that He had forged documents, “dodged supervision,” and misrepresented blood tests—even though no proof of those charges was released [emphasis mine], no outsiders were part of the inquiry, and He has not publicly admitted to any wrongdoing. (CRISPR scientists in China say the He fallout has affected their research.) Many scientists outside China also portrayed He as a rogue actor. “I think there has been a failure of self-regulation by the scientific community because of a lack of transparency,” virologist David Baltimore, a Nobel Prize–winning researcher at the California Institute of Technology (Caltech) in Pasadena and co-chair of the Hong Kong summit, thundered at He after the biophysicist’s only public talk on the experiment.

Because the Chinese government has revealed little and He is not talking, key questions about his actions are hard to answer. Many of his colleagues and confidants also ignored Science‘s requests for interviews. But Ryan Ferrell, a public relations specialist He hired, has cataloged five dozen people who were not part of the study but knew or suspected what He was doing before it became public. Ferrell calls it He’s circle of trust. [emphasis mine]

That circle included leading scientists—among them a Nobel laureate—in China and the United States, business executives, an entrepreneur connected to venture capitalists, authors of the NASEM report, a controversial U.S. IVF specialist [John Zhang] who discussed opening a gene-editing clinic with He [emphasis mine], and at least one Chinese politician. “He had an awful lot of company to be called a ‘rogue,’” says geneticist George Church [emphases mine], a CRISPR pioneer at Harvard University who was not in the circle of trust and is one of the few scientists to defend at least some aspects of He’s experiment.

Some people sharply criticized He when he brought them into the circle; others appear to have welcomed his plans or did nothing. Several went out of their way to distance themselves from He after the furor erupted. For example, the two onlookers in that informed consent meeting were Michael Deem, He’s Ph.D. adviser at Rice University in Houston, Texas, and Yu Jun, a member of the Chinese Academy of Sciences (CAS) and co-founder of the Beijing Genomics Institute, the famed DNA sequencing company in Shenzhen. Deem remains under investigation by Rice for his role in the experiment and would not speak with Science. In a carefully worded statement, Deem’s lawyers later said he “did not meet the parents of the reported CCR5-edited children, or anyone else whose embryos were edited.” But earlier, Deem cooperated with the Associated Press (AP) for its exclusive story revealing the birth of the babies, which reported that Deem was “present in China when potential participants gave their consent and that he ‘absolutely’ thinks they were able to understand the risks. [emphasis mine]”

Yu, who works at CAS’s Beijing Institute of Genomics, acknowledges attending the informed consent meeting with Deem, but he told Science he did not know that He planned to implant gene-edited embryos. “Deem and I were chatting about something else,” says Yu, who has sequenced the genomes of humans, rice, silkworms, and date palms. “What was happening in the room was not my business, and that’s my personality: If it’s not my business, I pay very little attention.”

Some people who know He and have spoken to Science contend it is time for a more open discussion of how the biophysicist formed his circle of confidants and how the larger circle of trust—the one between the scientific community and the public—broke down. Bioethicist William Hurlbut at Stanford University [emphasis mine] in Palo Alto, California, who knew He wanted to conduct the embryo-editing experiment and tried to dissuade him, says that He was “thrown under the bus” by many people who once supported him. “Everyone ran for the exits, in both the U.S. and China. I think everybody would do better if they would just openly admit what they knew and what they did, and then collectively say, ‘Well, people weren’t clear what to do. We should all admit this is an unfamiliar terrain.’”

Steve Lombardi, a former CEO of Helicos, reacted far more charitably. Lombardi, who runs a consulting business in Bridgewater, Connecticut, says Quake introduced him to He to help find investors for Direct Genomics. “He’s your classic, incredibly bright, naïve entrepreneur—I run into them all the time,” Lombardi says. “He had the right instincts for what to do in China and just didn’t know how to do it. So I put him in front of as many people as I could.” Lombardi says He told him about his embryo-editing ambitions in August 2017, asking whether Lombardi could find investors for a new company that focused on “genetic medical tourism” and was based in China or, because of a potentially friendlier regulatory climate, Thailand. “I kept saying to him, ‘You know, you’ve got to deal with the ethics of this and be really sure that you know what you’re doing.’”

In April 2018, He asked Ferrell to handle his media full time. Ferrell was a good fit—he had an undergraduate degree in neuroscience, had spent a year in Beijing studying Chinese, and had helped another company using a pre-CRISPR genome editor. Now that a woman in the trial was pregnant, Ferrell says, He’s “understanding of the gravity of what he had done increased.” Ferrell had misgivings about the experiment, but he quit HDMZ and that August moved to Shenzhen. With the pregnancy already underway, Ferrell reasoned, “It was going to be the biggest science story of that week or longer, no matter what I did.”

MIT Technology Review had broken a story early that morning China time, saying human embryos were being edited and implanted, after reporter Antonio Regalado discovered descriptions of the project that He had posted online, without Ferrell’s knowledge, in an official Chinese clinical trial registry. Now, He gave AP the green light to post a detailed account, which revealed that twin girls—whom He, to protect their identifies, named Lulu and Nana—had been born. Ferrell and He also posted five unfinished YouTube videos explaining and justifying the unprecedented experiment.

“He was fearful that he’d be unable to communicate to the press and the onslaught in a way that would be in any way manageable for him,” Ferrell says. One video tried to forestall eugenics accusations, with He rejecting goals such as enhancing intelligence, changing skin color, and increasing sports performance as “not love.” Still, the group knew it had lost control of the news. [emphasis mine]

… On 7 March 2017, 5 weeks after the California gathering, He submitted a medical ethics approval application to the Shenzhen HarMoniCare Women and Children’s Hospital that outlined the planned CCR5 edit of human embryos. The babies, it claimed, would be resistant to HIV as well as to smallpox and cholera. (The natural CCR5 mutation may have been selected for because it helps carriers survive smallpox and plague, some studies suggest—but they don’t mention cholera.) “This is going to be a great science and medicine achievement ever since the IVF technology which was awarded the Nobel Prize in 2010, and will also bring hope to numerous genetic disease patients,” the application says. Seven people on the ethics committee, chaired by Lin Zhitong—a one-time Direct Genomics director and a HarMoniCare administrator—signed the application, indicating they approved it.

[…] John Zhang, […] [emphasis mine] earned his medical degree in China and a Ph.D. in reproductive biology at the University of Cambridge in the United Kingdom. Zhang had made international headlines himself in September 2016, when New Scientist revealed that he had created the world’s first “three-parent baby” by using mitochondrial DNA from a donor egg to revitalize the egg of a woman with infertility and then inseminating the resulting egg. “This technology holds great hope for ladies with advanced maternal age to have their own children with their own eggs,” Zhang explains in the center’s promotional video, which alternates between Chinese and English. It does not mention that Zhang did the IVF experiment in Mexico because it is not now allowed in the United States. [emphasis mine]

When Science contacted Zhang, the physician initially said he barely knew He: [emphases mine] “I know him just like many people know him, in an academic meeting.”

After his talk [November 2018 at Hong Kong meeting], He immediately drove back to Shenzhen, and his circle of trust began to disintegrate. He has not spoken publicly since. “I don’t think he can recover himself through PR,” says Ferrell, who no longer works for He but recently started to do part-time work for He’s wife. “He has to do other service to the world.”

Calls for a moratorium on human germline editing have increased, although at the end of the Hong Kong summit, the organizing committee declined in its consensus to call for a ban. China has stiffened its regulations on work with human embryos, and Chinese bioethicists in a Nature editorial about the incident urged the country to confront “the eugenic thinking that has persisted among a small proportion of Chinese scholars.”

Church, who has many CRISPR collaborations in China, finds it inconceivable that He’s work surprised the Chinese government. China has “the best surveillance system in the world,” he says. “I conclude that they were totally aware of what he was doing at every step of the way, especially because he wasn’t particularly secretive about it.”

Benjamin Hurlbut, William’s son and a historian of biomedicine at Arizona State University in Tempe, says leaders in the scientific community should take a hard look at their actions, too. [emphases mine] He thinks the 2017 NASEM report helped give rise to He by following a well-established approach to guiding science: appointing an elite group to decide how scientists should be regulated. Benjamin Hurlbut, whose book Experiments in Democracy explores the governance of embryo research and bioethics, questions why small, scientist-led groups—à la the totemic Asilomar conference held in 1975 to discuss the future of recombinant DNA research—are seen as the best way to shape thinking about new technologies. Hurlbut has called for a “global observatory for gene editing” to convene meetings with diverse perspectives.

The prevailing notion that the scientific community simply “failed to see the rogue among the responsible,” Hurlbut says, is a convenient narrative for those scientific leaders and inhibits their ability to learn from such failures. [emphases mine] “It puts them on the right side of history,” he says. They failed to paint a bright enough red line, Hurlbut contends. “They are not on the right side of history because they contributed to this.”

If you have the time, I strongly recommend reading Cohen’s piece in its entirety. You’ll find links to the reports and more articles with in-depth reporting on this topic.

A little kindness and no regrets

William Hurlbut was interviewed in an As it happens (Canadian Broadcasting Corporation’ CBC) radio programme segment on December 30, 2020. This is an excerpt from the story transcript written by Sheena Goodyear (Note: A link has been removed),

Dr. William Hurlbut, a physician and professor of neural-biology at Stanford University, says he tried to warn He to slow down before it was too late. Here is part of his conversation with As It Happens guest host Helen Mann.

What was your reaction to the news that Dr. He had been sentenced to three years in prison?

My first reaction was one of sadness because I know Dr. He — who we call J.K., that’s his nickname.

I spent quite a few hours talking with him, and I’m just sad that this worked out this way. It didn’t work out well for him or for his country or for the world, in some sense.

Except the one good thing is it’s alerted us, it’s awakened the world, to the seriousness of the issues that are coming down toward us with biotechnology, especially in genetics.

How does he feel about [how] not just the Chinese government, but the world generally, responded to his experiment?

He was surprised, personally. But I had actually warned him that he was proceeding too fast, and I didn’t know he had implanted embryos.

We had several conversations before this was disclosed, and I warned him to go more slowly and to keep in conversation with the rest of the international scientific community, and more broadly the international perspectives on social and ethical matters.

He was doing that to some extent, but not deeply enough and not transparently enough.

It sounds like you were very thoughtful in the conversations you had with him and the advice you gave him. And I guess you operated with what you had. But do you have any regrets yourself?

I don’t have any regrets about the way I conducted myself. I regret that this happened this way for J.K., who is a very bright person, and a very nice person, a humble person.

He grew up in a poor urban farming village. He told me that at one point he wanted to ask out a certain girl that he thought was really pretty … but he was embarrassed to do so because her family owned the restaurant. And so you see how humble his origins were.

By the way, he did end up asking her out and he ended up marrying her, which is a happy story, except now they’re separated for years of crucial time, and they have little children. 

I know this is a bigger story than just J.K. and his family. But there’s a personal story to it too.

What happens He Jiankui? … Is his research career over?

It’s hard to imagine that a nation like China would not give him some some useful role in their society. A very intelligent and very well-educated young man. 

But on the other hand, he will be forever a sign of a very crucial and difficult moment for the human species. He’s not going outlive that.

It’s going to be interesting. I hope I get a chance to have good conversations with him again and hear his internal ruminations and perspectives on it all.

This (“I don’t have any regrets about the way I conducted myself”) is where Hurlbut lost me. I think he could have suggested that he’d reviewed and rethought everything and feels that he and others could have done better and maybe they need to rethink how scientists are trained and how we talk about science, genetics, and emerging technology. Interestingly, it’s his son who comes up with something closer to what I’m suggesting (this excerpt was quoted earlier in this posting from a December 30, 2019 article, by Carolyn Y. Johnson for the Washington Post),

“The fact that the individual at the center of the story has been punished for his role in it should not distract us from examining what supporting roles were played by others, particularly in the international scientific community and also the environment that shaped and encouraged him to push the limits,” said Benjamin Hurlbut [emphasis mine], associate professor in the School of Life Sciences at Arizona State University.

The man who CRISPRs himself approves

Josiah Zayner publicly injected himself with CRISPR in a demonstration (see my January 25, 2018 posting for details about Zayner, his demonstration, and his plans). As you might expect, his take on the He affair is quite individual. From a January 2, 2020 article for STAT, Zayner presents the case for Dr. He’s work (Note: Links have been removed),

When I saw the news that He Jiankui and colleagues had been sentenced to three years in prison for the first human embryo gene editing and implantation experiments, all I could think was, “How will we look back at what they had done in 100 years?”

When the scientist described his research and revealed the births of gene edited twin girls at the [Second] International Summit on Human Genome Editing in Hong Kong in late November 2018, I stayed up into the early hours of the morning in Oakland, Calif., watching it. Afterward, I couldn’t sleep for a few days and couldn’t stop thinking about his achievement.

This was the first time a viable human embryo was edited and allowed to live past 14 days, much less the first time such an embryo was implanted and the baby brought to term.

The majority of scientists were outraged at the ethics of what had taken place, despite having very little information on what had actually occurred.

To me, no matter how abhorrent one views [sic] the research, it represents a substantial step forward in human embryo editing. Now there is a clear path forward that anyone can follow when before it had been only a dream.

As long as the children He Jiankui engineered haven’t been harmed by the experiment, he is just a scientist who forged some documents to convince medical doctors to implant gene-edited embryos. The 4-minute mile of human genetic engineering has been broken. It will happen again.

The academic establishment and federal funding regulations have made it easy to control the number of heretical scientists. We rarely if ever hear of individuals pushing the ethical and legal boundaries of science.

The rise of the biohacker is changing that.

A biohacker is a scientist who exists outside academia or an institution. By this definition, He Jiankui is a biohacker. I’m also part of this community, and helped build an organization to support it.

Such individuals have much more freedom than “traditional” scientists because scientific regulation in the U.S. is very much institutionally enforced by the universities, research organizations, or grant-giving agencies. But if you are your own institution and don’t require federal grants, who can police you? If you don’t tell anyone what you are doing, there is no way to stop you — especially since there is no government agency actively trying to stop people from editing embryos.

… When a human embryo being edited and implanted is no longer interesting enough for a news story, will we still view He Jiankui as a villain?

I don’t think we will. But even if we do, He Jiankui will be remembered and talked about more than any scientist of our day. Although that may seriously aggravate many scientists and bioethicists, I think he deserves that honor.

Final comments

There can’t be any question that this was inevitable. One needs only to take a brief stroll through the history of science to know that scientists are going to push boundaries or, as in this case, press past an ill-defined grey zone.

The only scientists who are being publicly punished for hubris are Dr. He Jiankui and his two colleagues in China. Dr. Michael Deem is still working for Rice University as far as I can determine. Here’s how the Wikipedia entry for the He Jiankui Affair describes the investigation (Note: Links have been removed),

Michael W. Deem, an American bioengineering professor at Rice University and He’s doctoral advisor, was involved in the research, and was present when people involved in He’s study gave consent.[24] He was the only non-Chinese out of 10 authors listed in the manuscript submitted to Nature.[30] Deem came under investigation by Rice University after news of the work was made public.[58] As of 31 December 2019, the university had not released a decision.[59] [emphasis mine]

Meanwhile the scientists at Stanford are cleared. While there are comments about the Chinese government not being transparent, it seems to me that US universities are just as opaque.

What seems missing from all this discussion and opprobrium is that the CRISPR technology itself is problematic. My September 20, 2019 post features research into off-target results from CRISPR gene-editing and, prior, there was this July 17, 2018 posting (The CRISPR [clustered regularly interspaced short palindromic repeats]-CAS9 gene-editing technique may cause new genetic damage kerfuffle).

I’d like to see more discussion and, in line with Benjamin Hurlbut’s thinking, I’d like to see more than a small group of experts talking to each other as part of the process especially here in Canada and in light of efforts to remove our ban on germline-editing (see my April 26, 2019 posting for more about those efforts).
