Hacking Your Own Genes: A Recipe for Disaster
Editor's Note: Our Big Moral Question this month is: "Where should we draw a line, if any, between the use of gene editing for the prevention and treatment of disease, and for cosmetic enhancement?" It is illegal in the U.S. to develop human trials for the latter, even though some people think it should be acceptable. The most outspoken supporter recently resorted to self-experimentation using CRISPR in his own makeshift lab. But critics argue that "biohackers" like him are recklessly courting harm. LeapsMag invited a leading intellectual from the Center for Genetics and Society to share her perspective.
"I want to democratize science," says biohacker extraordinaire Josiah Zayner.
This is certainly a worthy-sounding sentiment. And it is central to the ethos of biohacking, a term that's developed a bit of sprawl. Biohacking can mean non-profit community biology labs that promote "citizen science," or clever but not necessarily safe or innocuous garage-based experiments with computers and genetics, or efforts at biological self-optimization via techniques including cybernetic implants, drug supplements, and intermittent fasting.
They appear to have given little thought to whether curiosity should be bound in any way by care for social consequence.
Against that messy background, what should we make of Zayner? The thirty-something ex-NASA scientist, who describes himself as "a global leader in the BioHacker movement," put his interpretation of democracy on display last October during a CRISPR-yourself performance at a San Francisco biotech conference. In that episode, he dramatically jabbed himself with a long needle, injecting his left forearm with a home-made gene-editing concoction that he said would disrupt his myostatin genes and bulk up his muscles.
Zayner sees himself, and is seen by some fellow biohackers, as a rebel hero: an intrepid scientific adventurer willing to risk his own well-being in the tradition of self-experimentation, eager to push the boundaries of established science in the service of forging innovative modes of discovery, ready to stand up to those stodgy bureaucrats at the FDA in the name of biohacker freedom.
To others, including some in the biohacker community, he's a publicity-seeking stunt man, perhaps deluded by touches of toxic masculinity and techno-entrepreneurial ideology, peddling snake-oil with oozing ramifications.
Zayner is hardly coy about his goals being larger than Popeye-like muscles. "I want to live in a world where people are genetically modifying themselves," he told FastCompany. "I think this is, like, literally, a new era of human beings," he mused to CBS in November. "It's gonna create a whole new species of humans."
Nor does he deign to conceal his tactics. The webpage of the company he launched to sell DIY gene-editing kits (which is advised by celebrity geneticist George Church) says that Zayner is "constantly pushing the boundaries of Science outside traditional environments." He is more explicit when performing: "Yes I am a criminal. And my crime is that of curiosity," he said last August to a biohacker audience in Oakland, which according to Gizmodo erupted in applause.
Regrettably, Zayner, along with some other biohackers and their defenders in the mainstream scientific world, appear to have given little thought to whether curiosity should be bound in any way by care for social consequence.
In December, the FDA issued a brief statement warning against using DIY kits for self-administered gene editing.
Though what's most directly at risk in Zayner's self-enhancement hack is his own safety, his bad-boy celebrity status is likely to encourage emulation. A few weeks after his San Francisco performance, 27-year-old Tristan Roberts took to Facebook Live to give himself a DIY gene modification injection to keep his HIV infection in check, because he doesn't like taking the regular medications that prevent AIDS. Whatever it was that he put into his body was provided by a company that Gizmodo describes as a "mysterious biotech firm with transhumanist leanings."
Zayner doesn't outright provide DIY gene hacks to others. But among his company's offerings are a free DIY Human CRISPR Guide and a $20 CRISPR-Cas9 plasmid that targets the human myostatin gene – the one that Zayner said he was targeting to make his muscles grow. Presumably to fend off legal problems, the product page says: "This product is not injectable or meant for direct human use" – a label as toothless as the fine print on cigarette packages that breaks the news that smoking causes cancer.
Some scientists warn that Zayner's style of biohacking carries considerable dangers. Microbiologist Brian Hanley, himself a self-experimenter who now opposes "biohacking humans," focuses on the technical difficulty of purifying what's being injected. "Screwing up can kill you from endotoxin," he says. "If you get in trouble, call me. I will do my best to instruct the physician how to save your life….But I make no guarantees you will survive."
Hanley also commented on the likely effectiveness of Zayner's effort: "Either Josiah Zayner is ignorant or he is deliberately misleading people. What he suggests cannot work as advertised."
Ensuring the safety and effectiveness of medical drugs and devices is the mandate of the US Food and Drug Administration. In December, the agency issued a brief statement warning against using DIY kits for self-administered gene editing, and saying flat out that selling them is against the law.
The stem cell field provides an unfortunate model of what can go wrong.
Zayner is dismissive of the safety risks. He asks in a Buzzfeed article whether DIY CRISPR should be considered more harmful than smoking or chemotherapy, "legal and socially acceptable activities that damage your genes." This is a strange line of argument, given the decades-long battles with the tobacco industry to raise awareness about smoking's significant harms, and since the side effects of chemotherapy are typically not undertaken by choice.
But the implications of what Zayner, Roberts, and some of their fellow biohackers are promoting ripple well beyond direct harms to individuals. Their rhetoric and vision affect the larger project of biomedicine, and the fraught relationships among drug researchers, pharmaceutical companies, clinical trial subjects, patients, and the public. Writing in Scientific American, Eleanor Pauwels of the Wilson Center, who is sympathetic to biohacking, lists the down sides: "blurred boundaries between treatments and self-experimentation, peer pressure to participate in trials, exploitation of vulnerable individuals, lack of oversight concerning quality control and risk of harm, and more."
These prospects are germane to the current state of human gene editing. After decades of dashed hopes, including deaths of research subjects, "gene therapy" may now be close to deserving the promise in its name. But with safety and efficacy still being evaluated, it's especially crucial to be honest about limitations as well as possibilities.
The stem cell field provides an unfortunate model of what can go wrong. Fifteen years ago, scientists, patient advocates, and even politicians routinely indulged in wildly over-optimistic enthusiasm about the imminence of stem cell therapies. That binge of irresponsible promotion helped create the current situation of widespread stem cell fraud: hundreds of clinics in the US alone selling unproven treatments to unsuspecting and sometimes desperate patients. Many have had their wallets lightened; some have gone blind or developed strange tumors that doctors have never before seen. The FDA is scrambling to address this still-worsening situation.
Zayner-style biohacking and promotion may also impact the ongoing controversy about whether new gene editing tools should be used in human reproduction to pre-determine the traits of future children and generations. Much of the widespread opposition to "human germline modification" is grounded in concern that it would lead to a society in which real or purported genetic advantages, marketed by fertility clinics to affluent parents, would exacerbate our already shameful levels of inequality and discrimination.
With powerful new technologies increasingly shaping the world, there's a lot riding on our capacity to democratize science. But as a society we don't yet have much practice at it.
Yet Zayner is all for it. In an interview in The Guardian, he comments, "DNA defines what a species is, and I imagine it wouldn't be too long into the future when the human species almost becomes a new species because of these modifications." He notes in a blog post, "We want to grow as a species and maybe change as a species. Whether that is curing disease or immortality or mutant powers is up to you."
This brings us back to Zayner's claim that he is working to democratize science.
The conviction that gene editing involves social and political challenges, not just technical matters, has been voiced at all points on the spectrum of perspective and uncertainty. But Zayner says there's been enough talk. "I want people to stop arguing about whether it's okay to use CRISPR or not use CRISPR….It's too late: I already made the choice for you. Argument over. Let's get on with it now. Let's use this to help people. Or to give people purple skin." (Emphasis added, in case there's any doubt about Zayner's commitment to democracy.)
With powerful new technologies increasingly shaping the world, there's a lot riding on our capacity to democratize science. But as a society we don't yet have much practice at it. In fact, we're not very sure what it would look like. It would clearly mean, as Arizona State University political scientist David Guston puts it, "considering the societal outcomes of research at least as attentively as the scientific and technological outputs." It would need broad participation and demand hard work.
The involvement of serious citizen scientists in such efforts, biohackers included, could be a very good thing. But Zayner's contributions to date have not been helpful.

A startup aims to make medicines in space
Story by Big Think
On June 12, a SpaceX Falcon 9 rocket deployed 72 small satellites for customers — including the world’s first space factory.
The challenge: In 2019, pharma giant Merck revealed that an experiment on the International Space Station had shown how to make its blockbuster cancer drug Keytruda more stable. That meant it could now be administered via a shot rather than through an IV infusion.
The key to the discovery was the fact that particles behave differently when freed from the force of gravity — seeing how its drug crystalized in microgravity helped Merck figure out how to tweak its manufacturing process on Earth to produce the more stable version.
Microgravity research could potentially lead to many more discoveries like this one, or even the development of brand-new drugs, but ISS astronauts only have so much time for commercial experiments.
“There are many high-performance products that are only possible to make in zero-gravity, which is a manufacturing capability that cannot be replicated in any factory on Earth.”-- Will Bruey.
The only options for accessing microgravity (or free fall) outside of orbit, meanwhile, are parabolic airplane flights and drop towers, and those are only useful for experiments that require less than a minute in microgravity — Merck’s ISS experiment took 18 days.
The idea: In 2021, California startup Varda Space Industries announced its intention to build the world’s first space factory, to manufacture not only pharmaceuticals but other products that could benefit from being made in microgravity, such as semiconductors and fiber optic cables.
This factory would consist of a commercial satellite platform attached to two Varda-made modules. One module would contain equipment capable of autonomously manufacturing a product. The other would be a reentry capsule to bring the finished goods back to Earth.
“There are many high-performance products that are only possible to make in zero-gravity, which is a manufacturing capability that cannot be replicated in any factory on Earth,” said CEO Will Bruey, who’d previously developed and flown spacecraft for SpaceX.
“We have a team stacked with aerospace talent in the prime of their careers, focused on getting working hardware to orbit as quickly as possible,” he continued.
“[Pharmaceuticals] are the most valuable chemicals per unit mass. And they also have a large market on Earth.” -- Will Bruey, CEO of Varda Space.
What’s new? At the time, Varda said it planned to launch its first space factory in 2023, and, in what feels like a first for a space startup, it has actually hit that ambitious launch schedule.
“We have ACQUISITION OF SIGNAL,” the startup tweeted soon after the Falcon 9 launch on June 12. “The world’s first space factory’s solar panels have found the sun and it’s beginning to de-tumble.”
During the satellite’s first week in space, Varda will focus on testing its systems to make sure everything works as hoped. The second week will be dedicated to heating and cooling the old HIV-AIDS drug ritonavir repeatedly to study how its particles crystalize in microgravity.
After about a month in space, Varda will attempt to bring its first space factory back to Earth, sending it through the atmosphere at hypersonic speeds and then using a parachute system to safely land at the Department of Defense’s Utah Test and Training Range.
Looking ahead: Ultimately, Varda’s space factories could end up serving dual purposes as manufacturing facilities and hypersonic testbeds — the Air Force has already awarded the startup a contract to use its next reentry capsule to test hardware for hypersonic missiles.
But as for manufacturing other types of goods, Varda plans to stick with drugs for now.
“[Pharmaceuticals] are the most valuable chemicals per unit mass,” Bruey told CNN. “And they also have a large market on Earth.”
“You’re not going to see Varda do anything other than pharmaceuticals for the next minimum of six, seven years,” added Delian Asparouhov, Varda’s co-founder and president.
Genes that protect health with Dr. Nir Barzilai
In today’s podcast episode, I talk with Nir Barzilai, a geroscientist, which means he studies the biology of aging. Barzilai directs the Institute for Aging Research at the Albert Einstein College of Medicine.
My first question for Dr. Barzilai was: why do we age? And is there anything to be done about it? His answers were encouraging. We can’t live forever, but we have some control over the process, as he argues in his book, Age Later.
Dr. Barzilai told me that centenarians differ from the rest of us because they have unique gene mutations that help them stay healthy longer. For most of us, the words “gene mutations” spell trouble - we associate these words with cancer or neurodegenerative diseases, but apparently not all mutations are bad.

Centenarians may have essentially won the genetic lottery, but that doesn’t mean the rest of us are predestined to have a specific lifespan and health span, or the amount of time spent living productively and enjoyably. “Aging is a mother of all diseases,” Dr. Barzilai told me. And as a disease, it can be targeted by therapeutics. Dr. Barzilai’s team is already running clinical trials on such therapeutics — and the results are promising.
More about Dr. Barzilai: He is scientific director of AFAR, American Federation for Aging Research. As part of his work, Dr. Barzilai studies families of centenarians and their genetics to learn how the rest of us can learn and benefit from their super-aging. He also organizing a clinical trial to test a specific drug that may slow aging.
