China vs. the West: Who Will Lead the Way in Embryo Editing Research?
Junjiu Huang and his team performed a miracle. A few miracles, actually. The researchers at Sun Yat-sen University in Guangzhou, China used the precise new DNA editing tool called CRISPR-CAS9 to edit a human embryo, replacing a single base. In doing so, they edited out beta-thalassemia, a blood disorder that reduces the production of hemoglobin, which can result in pale skin, fatigue, higher risk of blood clots, and other symptoms.
The race is on, and it's one everyone is going to try to win.
Huang's group, which did not respond to an email requesting comment for this story, injected 86 embryos and observed them for 48 hours. After that period -- a time long enough for CRISPR to split the DNA, other molecules to replace the base, and the embryos to grow to eight cells -- they tested 54 of the 71 that survived. Of those, only a few had the replacement base, according to a report of the study published in Protein & Cell. The experiment stopped there as the embryos, which had been acquired from local fertility clinics, were non-viable and not implanted.
But procreation was not the point. Far from it, in fact. The point was to demonstrate that it could be done, that in some far off (or not so far off) future, doctors could use CRISPR to eliminate diseases like Tay-Sachs, Huntington's, and cystic fibrosis that are caused by genetic mutations. Going a step further, perhaps they could eventually even tailor embryos that will develop into adults with specific traits like height and IQ.
Experts agree that we are far from that point, years if not decades away from leveraging CRISPR to cure diseases and decades if not centuries from being able to build designer babies. In that frame, Huang's achievement is just a small step, a blip on the timeline of human achievement. But seen in another light, it's yet another sign that we need to start talking about DNA modification now, establishing protocols, procedures, and plans that guide the subject before we get so far down the road that momentum is impossible to stop.
"The Chinese generally don't have the religious objections to embryo research that have held back research in the West."
It's essential to do so now because the idea of DNA modification -- a realization that humanity can control its evolution -- is compelling and attractive. Imagine a world where doctors and scientists could get rid of disease before it begins or ensure a baby would arrive with an Einstein-level IQ. That's intriguing, and also terrifying. What are the rules? How do we know when to stop? What guides the process? And how can we prevent mistakes or unwanted mutations? To borrow from another famous quotation, with great power comes great responsibility.
These aren't questions for Huang and the Chinese scientific community alone. A team from Oregon recently edited viable human embryos, eliminating a mutation that can lead to heart failure while preventing any unintended consequences. Just as importantly, every embryo they edited produced the intended genetic changes, a vital step since a partial success rate, known as mosaicism, could have devastating consequences to a future child.
In London at the Francis Crick Institute, researcher Kathy Niakan used CRISPR-CAS9 to "turn off" a gene that produces the protein OCT4. Without the protein, the fertilized egg could not produce a blastocyst, which is a key structure in early mammalian development that gives rise to an embryo and placenta. The recent study wasn't designed to go further, but the use of CRISPR was important. "One way to find out what a gene does in the developing embryo is to see what happens when it isn't working," said Dr. Niakan, who was the first scientist in the world to be granted regulatory approval to edit the genes of a human embryo for research. "Now that we have demonstrated an efficient way of doing this, we hope that other scientists will use it to find out the roles of other genes. If we knew the key genes that embryos need to develop successfully, we could improve IVF treatments and understand some causes of pregnancy failure. It may take many years to achieve such an understanding. Our study is just the first step."
The point is, CRISPR is here and it's not going anywhere. Scientists will continue to use it to learn about how humans develop. Yet different rules regarding CRISPR and embryo research in countries around the world will impact who gets there first. "I've heard the U.S.-China gene editing research parallel paths as Sputnik 2.0," said Kevin Doxzen, Science Communications Specialist at the University of California, Berkeley's Innovative Genomics Institute. The race is on, and it's one everyone is going to try to win.
Based on number of researchers and ease of regulations, the Chinese are the favorites to advance the science the furthest, the fastest.
Based on number of researchers and ease of regulations, the Chinese are the favorites to advance the science the furthest, the fastest. "The Chinese generally don't have the religious (predominantly Christian) or moral objections to embryo research that have held back research in the West," said Dr. Julian Savulescu, the Uehiro Professor of Practical Ethics and Director of the Oxford Martin Programme on Collective Responsibility for Infectious Disease at the University of Oxford. "This kind of research should be done, with the right sort of ethical oversight. The concern over China leading the way is that institutional oversight mechanisms are probably not as developed as in the West but so far, there is no evidence of breaches in standards of research ethics around the published research."
Or, put another way by bioethicist Dr. Arthur Caplan, founding director of NYU Langone Health's Division of Medical Ethics: "The Chinese, because they don't care and don't have moral reservations about embryo work, are doing what they want." This lack of aversion to working with embryos manifests itself in a couple of ways. The absence of moral qualms is one. Funding is another. Huang's study, and others like it, receive funding from the government. His, for example, was supported by two grants from the National Basic Research Program and three from the National Natural Science Foundation of China.
The U.S., on the other hand, bans any federal funding for research using human embryos. A law passed in 1996 states that federal dollars can't be used for: "research in which a human embryo or embryos are destroyed, discarded, or knowingly subjected to risk of injury or death greater than that allowed for research on fetuses." This restriction can shift incentives as many private institutions or commercial enterprises may have financial motivations or other goals beyond furthering basic research for the sake of general knowledge.
Embryo gene modification recently performed in the U.K. would merit 15 years in prison in Australia.
The embryo research ban is even more strict elsewhere. The Oviedo Convention, enacted in 1997, effectively prohibits germline engineering in members of the European Union. "In Italy, you can't destroy an embryo for any reason," said Alessandro Bertero, a postdoctoral fellow at the University of Washington's Department of Pathology who used to study in Italy. "It's illegal, and you'll go to jail." Later, Bertero was one of the researchers who worked with Dr. Niakan in London, an investigation that was allowed by the UK's Human Fertilisation and Embryology Authority. (In Australia, Niakan and her colleagues would face 15 years in jail due to the 2002 Prohibition of Human Cloning Act, which prohibits altering the genomes of embryonic cells.)
Despite the moral and legal reservations in the Western world, every person I spoke with for this story believed that better, more advanced studies and learning is happening in the U.S. and Europe. "The best studies in my opinion are from the labs in California and Oregon," Bertero said. "The quality of the work [in the Chinese study] – not being critical, but to be scientifically critical -- was just quick and dirty. It was, 'Let's just show that we have done it and get it out.' That doesn't mean that the quality of the work was good."
"If the Chinese or someone else starts beating our brains out, we're not going to want to stand by idly and not do these things."
How long that remains the case, however, is an open question. A significant number of groups in China are working on germline editing in human embryos. The concern is that the Chinese will emerge as a leader sooner rather than later because they can do research with embryos more easily than their Western counterparts.
For Caplan, the NYU professor, the embryo ban in the U.S. isn't based on science; it's rooted in something else. "It's 96 percent political," he said, laughing. "It has basically ground to a halt because no one wants to see repercussions take place if federal funding is involved. The NIH isn't involved. And they won't be."
What, in his mind, would get Americans to start realizing the benefits that embryo research would provide? "The perception that other countries were moving quickly to get the advantages of CRISPR and other gene modification techniques, finding more industrial and more medical purposes," he said. "If the Chinese or someone else starts beating our brains out, we're not going to want to stand by idly and not do these things."
Doing so would involve difficult conversations about the role of embryos in research. But these are philosophical questions that need to be approached at some point. From a U.S. perspective, doing so sooner while the American scientists still hold the technological and informational edge, is vital. Ignoring the issue doesn't make it go away.
Experts think a few changes should be made. The ban on federal funding should be lifted. Scientists and regulators should push for things like allowing federal funds to be used for the creation of new embryos for research purposes and the use of spare IVF embryos for research when the embryo would not be implanted into a woman. (Privately funded scientists can proceed in states that encourage embryonic stem cell research, like New York, New Jersey, and California, but not in restrictive ones like Louisiana and South Dakota, which prohibit creating or destroying embryos for research.) Policymakers could ban reproductive gene editing for now but look at it again after a certain period. A highly anticipated report issued earlier this year from an international guidance committee left the door open to eventual clinical trials with edited embryos. As of now, however, Congress will not allow the Food and Drug Administration to consider such trials. This is the future and it's the scientific community's responsibility to develop the ethical framework now.
"The US and Europe have the technological history and capacity to lead this research and should do so, ethically. We ought to be revising our laws and ethical guidelines to facilitate this kind of research," Professor Savulescu said. "But the challenge is to think constructively and ethically about this new technology, and to be leaders, not followers."
Niklas Anzinger is the founder of Infinita VC based in the charter city of Prospera in Honduras. Infinita focuses on a new trend of charter cities and other forms of alternative jurisdictions. Healso hosts a podcast about how to accelerate the future by unblocking “stranded technologies”.This spring he was a part of the network city experiment Zuzalu spearheaded by Ethereum founder Vitalik Buterin where a few hundred invited guests from the spheres of longevity, biotechnology, crypto, artificial intelligence and investment came together to form a two-monthlong community. It has been described as the world’s first pop-up city. Every morning Vitalians would descend on a long breakfast—the menu had been carefully designed by famed radical longevity self-experimenter Bryan Johnson—and there is where I first met Anzinger who told me about Prospera. Intrigued to say the least, I caught up with him later the same week and the following is a record of our conversation.
Q. We are sitting here in the so-called pop-up network state Zuzalu temporarily realized in the village of Lusticia Bay by the beautiful Mediterranean Sea. To me this is an entirely new concept: What is a network state?
A. A network state is a highly aligned online community that has a level of in-person civility; it crowd-funds territory, and it eventually seeks diplomatic recognition. In a way it's about starting a new country. The term was coined by the crypto influencer and former CTO of Coinbase Balaji Srinivasan in a book by the same title last year [2022]. What many people don't know is that it is a more recent addition or innovation in a space called competitive governance. The idea is that you have multiple jurisdictions competing to provide you services as a customer. When you have competition among governments or government service providers, these entities are forced to provide you with a better service instead of the often worse service at higher prices or higher taxes that we're currently getting. The idea went from seasteading, which was hardly feasible because of costs, to charter cities getting public/private partnerships with existing governments and a level of legal autonomy, to special economic zones, to now network states.
Q. How do network states compare to charter cities and similar jurisdictions?
A. Charter cities and special economic zones were legal forks from other existing states. Dubai, Shenzhen in China, to some degree Hong Kong, to some degree Singapore are some examples. There's a host of other charter cities, one of which I'm based in myself, which is Prospera located in Honduras on the island Roatán. Charter cities provide the full stack of governance; they provide new laws and regulations, business registration, tax codes and governance services, Estonia style: you log on to the government platform and you get services as a citizen.
When conceptualizing network states, Balagi Srinivasan turns the idea of a charter city a bit on its head: he doesn't want to start with this full stack because it's still very hard to get these kinds of partnerships with government. It's very expensive and requires lots of experience and lots of social capital. He is saying that network states could instead start as an online community. They could have a level of alignment where they trade with each other; they have their own economy; they meet in person in regular gatherings like we're doing here in Zuzulu for two months, and then they negotiate with existing governments or host cities to get a certain degree of legal autonomy that is centered around a moral innovation. So, his idea is: don't focus on building a completely new country or city; focus on a moral innovation.
Q. What would be an example of such a moral innovation?
A. An example would be longevity—life is good; death is bad—let's see what we can do to foster progress around that moral innovation and see how we can get legal forks from the existing system that allow us to accelerate progress in that area. There is an increasing realization in the science that there are hallmarks of aging and that aging is a cause of other diseases like cancer, ALS or Alzheimer's. But aging is not recognized as a disease by the FDA in the United States and in most countries around the world, so it's very hard to get scientific funding for biotechnology that would attack the hallmarks of aging and allow us potentially to reverse aging and extend life. This is a significant shortcoming of existing government systems that groups such as the ones that have come together here in Montenegro are now seeking alternatives too. Charter cities and now network states are such alternatives.
Q. Would it not be better to work within the current systems, and try to improve them, rather than abandon them for new experimental jurisdictions?
A. There are numerous failures of public policies. These failures are hard, if not impossible, to reverse, because as soon as you have these policies, you have entrenched interests who benefit from the regulations. The only way to disrupt incumbent industries is with start-ups, but the way the system is set up makes it excessively hard for such start-ups to become big companies. In fact, larger companies are weaponizing the legal system against small companies, because they can afford the lawyers and the fixed cost of compliance.
I don't believe that our institutions in many developed countries are beyond hope. I just think it's easier to change them if you could point at successful examples. ‘Hey, this country or this zone is already doing it very successfully’; if they can extend people’s lifespan by 10 years, if they can reduce maternal mortality, and if they have a massive medical tourism where people come back healthier, then that is just very embarrassing for the FDA.
Q. Perhaps a comparison here would be the relationship between Hong Kong and China?
A. Correct, so having Hong Kong right in front of your door … ‘Hey, this capitalism thing seems to work, why don't we try it here?’ It was due to the very bold leadership by Deng Xiaoping that they experimented with it in the development zone of Shenzhen. It worked really well and then they expanded with more special economic zones that also worked.
Próspera is a private city and special economic zone on the island of Roatán in the Central American state of Honduras.
Q. Tell us about Prospera, the charter city in Honduras, that you are intimately connected with.
A. Honduras is a very poor country. It has a lot of crime, never had a single VC investment, and has a GDP per capita of 2,000 per year. Honduras has suffered tremendously. The goal of these special economic zones is to bring in economic development. That's their sole purpose. It's a homegrown innovation from Honduras that started in 2009 with a very forward-thinking statesman, Octavio Sanchez, who was the chief of staff to the president of Honduras, and then president. He had his own ideas about making Honduras a more decentralized system, where more of the power lies in the municipalities.
Inspired by the ideas of Nobel laureate economist Paul Romer, who gave a famous Ted Talk in 2009 about charter cities, Sanchez initiated a process that lasted for years and eventually led to the creation of a special economic zone legal regime that’s anchored in the Hunduran constitution that provides the highest legal autonomy in the world to these zones. There are today three special economic zones approved by the Honduran government: Prospera, Ciudad Morazan and Orchidea.
Q. How did you become interested and then involved in Prospera?
A. I read about it first in an article by Scott Alexander, a famous rationalist blogger, who wrote a very long article about Prospera, and I thought, this is amazing! Then I came to Prospera and I found it to be one of the most if not the most exciting project in the world going on right now and that it also opened my heart to the country and its people. Most of my friends there are Honduran, they have been working on this for 10 or more years. They want to remake Honduras and put it on the map as the place in the world where this legal and governance innovation started.
Q. To what extent is Prospera autonomous relative to the Honduran government?
A. What's interesting about the Honduran model is that it's anchored within the Honduran constitution, and it has a very clear framework for what's possible and what's not possible, and what's possible ensures the highest degree of legal autonomy anywhere seen in the world. Prospera has really pushed the model furthest in creating a common law-based polycentric legal system. The idea is that you don't have a legislature, instead you have common law and it's based on the best practice common law principles that a legal scholar named Tom W. Bell created.
One of the core ideas is that as a business you're not obligated to follow one regulatory monopoly like the FDA. You have regulatory flexibility so you can choose what you're regulated under. So, you can say: ‘if I do a medical clinic, I do it under Norwegian law here’. And you even have the possibility to amend it a bit. You're still required to have liability insurance, and have to agree to binding arbitration in case there's a legal dispute. And your insurance has to approve you. So, under that model the insurance becomes the regulator and they regulate through prices. The limiting factor is criminal law; Honduran criminal law fully applies. So does immigration law. And we pay taxes.
Q. Is there also an idea of creating a kind of healthy living there, and encourage medical tourism?
A. Yes, we specifically look for legal advantages in autonomy around creating new drugs, doing clinical trials, doing self-medication and experimentation. There is a stem cell clinic here and they're doing clinical trials. The island of Roatán is very easily accessible for American tourists. It's a beautiful island, and it's for regulatory reasons hard to do stem cell therapies in the United States, so they're flying in patients from the United States. Most of them are very savvy and often have PhDs in biotech and are able to assess the risk for themselves of taking drugs and doing clinical trials. We're also going to get a wellness center, and there have been ideas around establishing a peptide clinic and a compound pharmacy and things like that. We are developing a healthcare ecosystem.
Q. This kind of experimental tourism raises some ethical issues. What happens if patients are harmed? And what are the moral implications for society of these new treatments?
A. As a moral principle we believe in medical freedom: people have rights over their bodies, even at the (informed) risk of harm to themselves if no unconsenting third-parties are harmed; this is a fundamental right currently not protected effectively.
What we do differently is not changing ethical norms around safety and efficacy, we’re just changing the institutional setup. Instead of one centralized bureaucracy, like the FDA, we have regulatory pluralism that allows different providers of safety and efficacy to compete under market rules. Like under any legal system, common law in Prospera punishes malpractice, fraud, murder etc. This system will still produce safe and effective drugs, and it will still work with common sense legal notions like informed consent and liability for harm. There are regulations for medical practice, there is liability insurance and things like that. It will just do so more efficiently than the current way of doing things (unless it won’t, in which case it will change and evolve – or fail).
A direct moral benefit ´to what we do is that we increase accessibility. Typical gene therapies on the market cost $1 million dollars in the US. The gene therapy developed in Prospera costs $25,000. As to concern about whether such treatments are problematic, we do not share this perspective. We are for advancing science responsibly and we believe that both individuals and society stand to gain from improving the resiliency of the human body through advanced biotechnology.
Q. How does Prospera relate to the local Honduran population?
A. I think it's very important that our projects deliver local benefits and that they're well anchored in local communities. Because when you go to a new place, you're seen as a foreigner, and you're seen as potentially a danger or a threat. The most important thing for Prospera and Ciudad Morazan is to show we're creating jobs; we're creating employment; we're improving people's lives on the ground. Prospera is directly and indirectly employing 1,100 people. More than 2/3 of the people who are working for Prospera are Honduran. It has a lot of local service workers from the island, and it has educated Hondurans from the mainland for whom it's an alternative to going to the United States.
Q. What makes a good Prosperian citizen?
A. People in Prospera are very entrepreneurial. They're opening companies on a small scale. For example, Vehinia, who is the cook in the kitchen at Prospera, she's from the neighboring village and she started an NGO that is now funding a school where children from the local village can go to instead of a school that's 45 minutes away. There's very much a spirit of ‘let's exchange and trade with each other’. Some people might see that as a bit too commercial, but that's something about the culture that people accept and that people see as a good thing.
Q. Five years from now, if everything goes well, what do we see in Prospera?
A. I think Prospera will have at least 10,000 residents and I think Honduras hopefully will have more zones. There could be zones with a thriving industrial sector and sort of a labor-intensive economy and some that are very strong in pharmaceuticals, there could also be other zones for synthetic biology, and other zones focused on agriculture. The zones of Prospera, Ciudad Morazan and Orchidea are already showing the results we want to see, the results that we will eventually be measured by, and I'm tremendously excited about Honduras.
How to Measure Your Stress, with Dr. Rosalind Picard
Today’s podcast guest is Rosalind Picard, a researcher, inventor named on over 100 patents, entrepreneur, author, professor and engineer. When it comes to the science related to endowing computer software with emotional intelligence, she wrote the book. It’s published by MIT Press and called Affective Computing.
Dr. Picard is founder and director of the MIT Media Lab’s Affective Computing Research Group. Her research and engineering contributions have been recognized internationally. For example, she received the 2022 International Lombardy Prize for Computer Science Research, considered by many to be the Nobel prize in computer science.
Through her research and companies, Dr. Picard has developed wearable sensors, algorithms and systems for sensing, recognizing and responding to information about human emotion. Her products are focused on using fitness trackers to advance clinical quality treatments for a range of conditions.
Meanwhile, in just the past few years, numerous fitness tracking companies have released products with their own stress sensors and systems. You may have heard about Fitbit’s Stress Management Score, or Whoop’s Stress Monitor – these features and apps measure things like your heart rhythm and a certain type of invisible sweat to identify stress. They’re designed to raise awareness about forms of stress such as anxieties and anger, and suggest strategies like meditation to relax in real time when stress occurs.
But how well do these off-the-shelf gadgets work? There’s no one more knowledgeable and experienced than Rosalind Picard to explain the science behind these stress features, what they do exactly, how they might be able to help us, and their current shortcomings.
Dr. Picard is a member of the National Academy of Engineering and a Fellow of the National Academy of Inventors, and a popular speaker who’s given over a hundred invited keynote talks and a TED talk with over 2 million views. She holds a Bachelors in Electrical Engineering from Georgia Tech, and Masters and Doctorate degrees in Electrical Engineering and Computer Science from MIT. She lives in Newton, Massachusetts with her husband, where they’ve raised three sons.
In our conversation, we discuss stress scores on fitness trackers to improve well-being. She describes the difference between commercial products that might help people become more mindful of their health and products that are FDA approved and really capable of advancing the science. We also talk about several fascinating findings and concepts discovered in Dr. Picard’s lab including the multiple arousal theory, a phenomenon you’ll want to hear about. And we explore the complexity of stress, one reason it’s so tough to measure. For example, many forms of stress are actually good for us. Can fitness trackers tell the difference between stress that’s healthy and unhealthy?
