As a species, we are prone to weaponizing. There is a famous anecdote from Wulf Schievenhovel, a German anthropologist who was working in the highlands of New Guinea studying a local tribe. One day, he offered two tribesmen a flight in an airplane. They duly accepted but showed up with two large stones. When he asked why, they told him that they wanted to drop them on a neighboring village. Ethologist Frans de Waal later remarked on this story that Schievenhovel had effectively "witnessed the invention of the bomb."
Today you don't have to be Putin or Kim Jong Un to pose an existential threat.
Modern technology has given us access to more than just rocks. In 2011, a Swedish man was arrested after attempting a nuclear fission in his kitchen. And in the inaugural issue of this magazine, my colleague Hank Greely raised a terrifying prospect:
"do-it-yourself hobbyists can use CRISPR [gene editing]… to change the genomes of whole species of living things – domestic or wild; animal, vegetable, or microbial – cheaply, easily, and before we even know it is happening."
In science fiction, it is typically governments that take over technologies and use them for evil. That risk is of course no fiction. It is an ongoing problem that we have addressed through institutions: democracies, constitutions, legal systems and international treaties, and groups working together as checks and balances. It isn't perfect, but it has worked (so far).
Today you don't have to be Putin or Kim Jong Un to pose an existential threat. We are rapidly acquiring the technological ability for individuals and groups not just to cause major harm, but to do so exactly as Hank said: "cheaply, easily, and before we even know it is happening."
How should we address this problem? Together with Ingmar Persson, a fellow philosophy professor at Gothenburg, Sweden, I have argued that while education, institutions and good policing are important, we may need to think more radically.
We could adapt our biology so that we can appreciate the suffering of foreign or future people in the same instinctive way we do our friends and neighbors.
We evolved, along with the New Guinea tribesmen, to care about our small group and to be suspicious of outsiders. We evolved to cooperate well within our group, at a size where we could keep an eye on free riders. And we evolved to have the ability, and occasionally the desire to harm others, but with a natural limit on the amount of harm we could do—at least before others could step in to prevent, punish or kill us.
Our limitations have also become apparent in another form of existential threat: resource depletion. Despite our best efforts at educating, nudging, and legislating on climate change, carbon dioxide emissions in 2017 are expected to come in at the highest ever following a predicted rise of 2 percent. Why? We aren't good at cooperating in larger groups where freeriding is not easily spotted. We also deal with problems in order of urgency. A problem close by is much more significant to us than a problem in the future. That's why even if we accept there is a choice between economic recession now or natural disasters and potential famine in the future, we choose to carry on drilling for oil. And if the disasters and famine are present day, but geographically distant, we still choose to carry on drilling.
So what is our radical solution? We propose that there is a need for what we call moral bioenhancement. That is, for seeking a biological intervention that can help us overcome our evolved moral limitations. For example, adapting our biology so that we can appreciate the suffering of foreign or future people in the same instinctive way we do our friends and neighbors. Or, in the case of individuals, in addressing the problem of psychopathy from a biological perspective.
There is no reason in principle why humans could not be genetically modified...to make them kinder, happier, more conscientious, altruistic and just.
We have been dramatically successful at modifying various moral characteristics of non-human animals. Over ten thousand years or so, we have turned wolves into dogs by selective breeding, and those dogs into breeds with behavioural as well as physical characteristics: certain breeds can be faithful, hard working, good tempered and intelligent (or the opposite). Scientists have manipulated the expression of genes in prairie voles to cause them to form a mate bond more quickly, and in monkeys to make them work harder. There is no reason in principle why humans could not be genetically modified using gene editing, or their brains modified in other ways, to make them kinder, happier, more conscientious, altruistic and just.
One objection is that this is a pipe dream: even if it is acceptable to do this, it is so unlikely to be achievable, it is not worth pursuing. However, research has shown that we are already morally modified. This is widely accepted when it comes to negative effects. For example, we all know that alcohol can lead people to aggressive or other destructive behaviours that they would not have countenanced sober. In a 2008 case, a retired UK teacher was cleared of child pornography charges after he successfully argued his behaviour was caused by a drug prescribed for his Parkinson's disease. There is also evidence that we can be morally modified in a more positive direction. For example, SSRIs like Prozac, a class of drugs widely used to treat depression, have been shown to act on healthy volunteers to make them more cooperative and less critical.
Another objection is that we need the negative aspects of our human character. We need people who can fight wars. We need to be able to blot out the suffering of the wider world: to experience it as we would if it applied to our nearest and dearest would be unbearable. This might be so. If aggressiveness and denial, or strong bonding to small communities, are important traits, it is important that we understand how, and to what degree, they should be controlled. It is unlikely that nature has dished out exactly the right levels of all morally relevant characteristics on an individual or population level. We don't claim to have all the answers to what characteristics we need to enhance, and what characteristics we need to diminish. But we see no reason to believe that the status quo is the optimum.
We haven't argued that we should go blindly in now with half-baked moral enhancers, or that we should forget about moral education, or legal solutions. Evolution has a built-in response to existential threats through adaptation. But adaptation takes generations and can't deal with threats that take out a whole population. Some threats are too important —and too urgent—to be left to chance.
The white two-seater car that rolls down the street in the Sorrento Valley of San Diego looks like a futuristic batmobile, with its long aerodynamic tail and curved underbelly. Called 'Sol' (Spanish for "sun"), it runs solely on solar and could be the future of green cars. Its maker, the California startup Aptera, has announced the production of Sol, the world's first mass-produced solar vehicle, by the end of this year. Aptera co-founder Chris Anthony points to the sky as he says, "On this sunny California day, there is ample fuel. You never need to charge the car."
If you live in a sunny state like California or Florida, you might never need to plug in the streamlined Sol because the solar panels recharge while driving and parked. Its 60-mile range is more than the average commuter needs. For cloudy weather, battery packs can be recharged electronically for a range of up to 1,000 miles. The ultra-aerodynamic shape made of lightweight materials such as carbon, Kevlar, and hemp makes the Sol four times more energy-efficient than a Tesla, according to Aptera. "The material is seven times stronger than steel and even survives hail or an angry ex-girlfriend," Anthony promises.
Co-founder Steve Fambro opens the Sol's white doors that fly upwards like wings and I get inside for a test drive. Two dozen square solar panels, each the size of a large square coaster, on the roof, front, and tail power the car. The white interior is spartan; monitors have replaced mirrors and the dashboard. An engineer sits in the driver's seat, hits the pedal, and the low-drag two-seater zooms from 0 to 60 in 3.5 seconds.
It feels like sitting in a race car because the two-seater is so low to the ground but the car is built to go no faster than 100 or 110 mph. The finished car will weigh less than 1,800 pounds, about half of the smallest Tesla. The average car, by comparison, weighs more than double that. "We've built it primarily for energy efficiency," Steve Fambro says, explaining why the Sol has only three wheels. It's technically an "auto-cycle," a hybrid between a motorcycle and a car, but Aptera's designers are also working to design a four-seater.
There has never been a lack of grand visions for the future of the automobile, but until these solar cars actually hit the streets, nobody knows how the promises will hold up.
Transportation is currently the biggest source of greenhouse gases. Developing an efficient solar car that does not burden the grid has been the dream of innovators for decades. Every other year, dozens of innovators race their self-built solar cars 2,000 miles through the Australian desert.
More effective solar panels are finally making the dream mass-compatible, but just like other innovative car ideas, Aptera's vision has been plagued with money problems. Anthony and Fambro were part of the original crew that founded Aptera in 2006 and worked on the first prototype around the same time Tesla built its first roadster, but Aptera went bankrupt in 2011. Anthony and Fambro left a year before the bankruptcy and went on to start other companies. Among other projects, Fambro developed the first USDA organic vertical farm in the United Arab Emirates, and Anthony built a lithium battery company, before the two decided to buy Aptera back. Without a billionaire such as Elon Musk bankrolling the risky process of establishing a whole new car production system from scratch, the huge production costs are almost insurmountable.
But Aptera's founders believe they have found solutions for the entire production process as well as the car design. Most parts of the Sol's body can be made by 3D printers and assembled like a Lego kit. If this makes you think of a toy car, Anthony assures potential buyers that the car aced stress tests and claims it's safer than any vehicle on the market, "because the interior is shaped like an egg and if there is an impact, the pressure gets distributed equally." However, Aptera has yet to release crash test safety data so outside experts cannot evaluate their claims.
Instead of building a huge production facility, Anthony and Fambro envision "micro-factories," each less than 10,000 square feet, where a small crew can assemble cars on demand wherever the orders are highest, be it in California, Canada, or China.
If a part of the Sol breaks, Aptera promises to send replacement parts to any corner of the world within 24 hours, with instructions. So a mechanic in a rural corner in Arkansas or China who never worked on a solar car before simply needs to download the instructions and replace the broken part. At least that's the idea. "The material does not rust nor fatigue," Fambro promises. "You can pass the car onto your grandchildren. When more efficient solar panels hit the market, we simply replace them."
More than 11,000 potential buyers have already signed up; the cheapest model costs around $26,000 USD and Aptera expects the first cars to ship by the end of the year.
Two other solar carmakers are vying for the pole position in the race to be the first to market: The German startup Sono has also announced it will also produce its first solar car by the end of this year. The price tag for the basic model is also around $26,000, but its concept is very different. From the outside, the Sion looks like a conservative minivan for a family; only a closer look reveals that the dark exterior is made of solar panels. Sono, too, nearly went bankrupt a few years ago and was saved through a crowdfunding campaign by enthusiastic fans.
Meanwhile, Norwegian company Lightyear wants to produce a sleek solar-powered luxury sedan by the end of the year, but its price of around $180,000 makes it unaffordable for most buyers.
There has never been a lack of grand visions for the future of the automobile, but until these solar cars actually hit the streets, nobody knows how the promises will hold up. How often will the cars need to be repaired? What happens when snow and ice cover the solar panels? Also, you can't park the car in a garage if you need the sun to charge it.
Critics, including students at the Solar Car team at the University of Michigan, say that mounting solar panels on a moving vehicle will never yield the most efficient results compared to static panels. Also, they are quick to point out that no company has managed to overcome the production hurdles yet. Others in the field also wonder how well the solar panels will actually work.
"It's important to realize that the solar mileage claims by these companies are likely the theoretical best case scenario but in the real world, solar range will be significantly less when you factor in shading, parking in garages, and geographies with lower solar irradiance," says Evan Stumpges, the team coordinator for the American Solar Challenge, a competition in which enthusiasts build and race solar-powered cars. "The encouraging thing is that I have seen videos of real working prototypes for each of these vehicles which is a key accomplishment. That said, I believe the biggest hurdle these companies have yet to face is successfully ramping up to volume production and understanding what their profitability point will be for selling the vehicles once production has stabilized."
Professor Daniel M. Kammen, the founding director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley, and one of the world's foremost experts on renewable energy, believes that the technical challenges have been solved, and that solar cars have real advantages over electric vehicles.
"This is the right time to be bullish. Cutting out the charging is a natural solution for long rides," he says. "These vehicles are essentially solar panels and batteries on wheels. These are now record low-cost and can be built from sustainable materials." Apart from Aptera's no-charge technology, he appreciates the move toward no-conflict materials. "Not only is the time ripe but the youth movement is pushing toward conflict-free material and reducing resource waste....A low-cost solar fleet could be really interesting in relieving burden on the grid, or you could easily imagine a city buying a bunch of them and connecting them with mass transit." While he has followed all three new solar companies with interest, he has already ordered an Aptera car for himself, "because it's American and it looks the most different."
After taking a spin in the Sol, it is startling to switch back into a regular four-seater. Rolling out of Aptera's parking lot onto the freeway next to all the oversized gas guzzlers that need to stop every couple of hundreds of miles to fill up, one can't help but think: We've just taken a trip into the future.
Last summer, when fast and cheap Covid tests were in high demand and governments were struggling to manufacture and distribute them, a group of independent scientists working together had a bit of a breakthrough.
Working on the Just One Giant Lab platform, an online community that serves as a kind of clearing house for open science researchers to find each other and work together, they managed to create a simple, one-hour Covid test that anyone could take at home with just a cup of hot water. The group tested it across a network of home and professional laboratories before being listed as a semi-finalist team for the XPrize, a competition that rewards innovative solutions-based projects. Then, the group hit a wall: they couldn't commercialize the test.
They wanted to keep their project open source, making it accessible to people around the world, so they decided to forgo traditional means of intellectual property protection and didn't seek patents. (They couldn't afford lawyers anyway). And, as a loose-knit group that was not supported by a traditional scientific institution, working in community labs and homes around the world, they had no access to resources or financial support for manufacturing or distributing their test at scale.
But without ethical and regulatory approval for clinical testing, manufacture, and distribution, they were legally unable to create field tests for real people, leaving their inexpensive, $16-per-test, innovative product languishing behind, while other, more expensive over-the-counter tests made their way onto the market.
Who Are These Radical Scientists?
Independent, decentralized biomedical research has come of age. Also sometimes called DIYbio, biohacking, or community biology, depending on whom you ask, open research is today a global movement with thousands of members, from scientists with advanced degrees to middle-grade students. Their motivations and interests vary across a wide spectrum, but transparency and accessibility are key to the ethos of the movement. Teams are agile, focused on shoestring-budget R&D, and aim to disrupt business as usual in the ivory towers of the scientific establishment.
Ethics oversight is critical to ensuring that research is conducted responsibly, even by biohackers.
Initiatives developed within the community, such as Open Insulin, which hopes to engineer processes for affordable, small-batch insulin production, "Slybera," a provocative attempt to reverse engineer a $1 million dollar gene therapy, and the hundreds of projects posted on the collaboration platform Just One Giant Lab during the pandemic, all have one thing in common: to pursue testing in humans, they need an ethics oversight mechanism.
These groups, most of which operate collaboratively in community labs, homes, and online, recognize that some sort of oversight or guidance is useful—and that it's the right thing to do.
But also, and perhaps more immediately, they need it because federal rules require ethics oversight of any biomedical research that's headed in the direction of the consumer market. In addition, some individuals engaged in this work do want to publish their research in traditional scientific journals, which—you guessed it—also require that research has undergone an ethics evaluation. Ethics oversight is critical to ensuring that research is conducted responsibly, even by biohackers.
Bridging the Ethics Gap
The problem is that traditional oversight mechanisms, such as institutional review boards at government or academic research institutions, as well as the private boards utilized by pharmaceutical companies, are not accessible to most independent researchers. Traditional review boards are either closed to the public, or charge fees that are out of reach for many citizen science initiatives. This has created an "ethics gap" in nontraditional scientific research.
Biohackers are seen in some ways as the direct descendents of "white hat" computer hackers, or those focused on calling out security holes and contributing solutions to technical problems within self-regulating communities. In the case of health and biotechnology, those problems include both the absence of treatments and the availability of only expensive treatments for certain conditions. As the DIYbio community grows, there needs to be a way to provide assurance that, when the work is successful, the public is able to benefit from it eventually. The team that developed the one-hour Covid test found a potential commercial partner and so might well overcome the oversight hurdle, but it's been 14 months since they developed the test--and counting.
In short, without some kind of oversight mechanism for the work of independent biomedical researchers, the solutions they innovate will never have the opportunity to reach consumers.
In a new paper in the journal Citizen Science: Theory & Practice, we consider the issue of the ethics gap and ask whether ethics oversight is something nontraditional researchers want, and if so, what forms it might take. Given that individuals within these communities sometimes vehemently disagree with each other, is consensus on these questions even possible?
We learned that there is no "one size fits all" solution for ethics oversight of nontraditional research. Rather, the appropriateness of any oversight model will depend on each initiative's objectives, needs, risks, and constraints.
We also learned that nontraditional researchers are generally willing (and in some cases eager) to engage with traditional scientific, legal, and bioethics experts on ethics, safety, and related questions.
We suggest that these experts make themselves available to help nontraditional researchers build infrastructure for ethics self-governance and identify when it might be necessary to seek outside assistance.
Independent biomedical research has promise, but like any emerging science, it poses novel ethical questions and challenges. Existing research ethics and oversight frameworks may not be well-suited to answer them in every context, so we need to think outside the box about what we can create for the future. That process should begin by talking to independent biomedical researchers about their activities, priorities, and concerns with an eye to understanding how best to support them.
