CRISPR People: The Science and Ethics of Editing Humans
by Henry T. Greely
Published 22 Jan 2021

As far as Berg’s Nobel Prize goes, no one doubts that he and his lab made major contributions to the field and were driving forces in its advance, but Berg had another role that made him stand out from the rest of the recombinant DNA crowd. He was a leader, arguably the leader, in organizing a temporary moratorium on recombinant DNA research and in organizing and running the famous 1975 Asilomar Conference on recombinant DNA at which the moratorium was discussed. And the Asilomar Conference is an essential part of this story. The Asilomar Conference, or, to give it its full name, the Asilomar Conference on Recombinant DNA Molecules, was held on February 24, 25, and 26, 1975, at the Asilomar State Beach and Conference Grounds, an unusual unit of the California State Park system, located on the coast just south of Monterey, California (and one of the loveliest places in the world).7 It had been spawned in June 1973 at a Gordon Conference on the topic of nucleic acids.

Life's Greatest Secret: The Race to Crack the Genetic Code
by Matthew Cobb
Published 6 Jul 2015

However, a great deal of further work will be needed before this approach can be applied in the real world, and I suspect few scientists – or readers – would want to rely solely on this technique to ensure biosecurity.52 These responsible approaches to the potential impact of a new technique of unprecedented power are a direct descendant of the Asilomar conference on recombinant DNA that so successfully guided science as it was catapulted into the new world of genetic manipulation. In 2008, Paul Berg reflected on the impact of the Asilomar conference: In the 33 years since Asilomar, researchers around the world have carried out countless experiments with recombinant DNA without reported incident.

Whole Earth Discipline: An Ecopragmatist Manifesto
by Stewart Brand
Published 15 Mar 2009

Monstrous organisms would be created, environmentalists said, that could threaten everything living. There would be insulin-shock epidemics and tumor plagues. The Cambridge and Berkeley city councils—both cities the home of major universities—outlawed recombinant-DNA research. The U.S. Congress began introducing restrictive legislation. That was the atmosphere that led to the Asilomar Conference on Recombinant DNA Molecules in California in February 1975. Coming from all over the world, some 146 genetic scientists and related professionals convened for four days to regulate their research. They instituted an array of laboratory containment practices and mandated the use of organisms that could not live outside the lab.

Innovation and Its Enemies
by Calestous Juma
Published 20 Mar 2017

Questioning Science Regulatory uncertainties plagued genetic engineering from the beginning, but the scientific community self-regulated those concerns in many instances, understanding the potential dangers genetic engineering posed to the public and to science. Genetic engineering’s transformative power was evident from the time the gene-cloning technique was developed in 1973 by Herbert Boyer and Stanley Cohen. Two years later, participants at the 1975 Asilomar Conference on Recombinant DNA called for a voluntary moratorium on genetic engineering to allow the National Institutes of Health to develop safety guidelines for what some feared might be risky experiments. By being proactive, the scientific community took responsibility for designing safety guidelines that were themselves guided by the best available scientific knowledge and principles.

Future War: Preparing for the New Global Battlefield
by Robert H. Latiff
Published 25 Sep 2017

Since World War II, numerous efforts have been made to deal with issues of technology, weapons research, and ethics. These include the 1946 Nuremberg trials, the 1972 Biological Weapons Convention, the 1993 Chemical Weapons Convention, and efforts by scientists to place restrictions on biomedical, genomic, and nanotechnology research. Scientists attending the Asilomar Conference on Recombinant DNA, near Monterey, California, in 1975 recognized the potential dangers of such DNA research and declared a moratorium until safe and ethical procedures could be developed. The guidelines developed were voluntary, but have been assiduously followed. Rules and theory are one thing, practical applications another.

The Singularity Is Nearer: When We Merge with AI
by Ray Kurzweil
Published 25 Jun 2024

No one would have preexisting immunity, and the result would be a pandemic capable of ravaging the human population.[26] The 2019–2023 coronavirus pandemic offers us a pale glimpse of what such a catastrophe could be like. The specter of this possibility was the impetus for the original Asilomar Conference on Recombinant DNA in 1975, fifteen years before the Human Genome Project was initiated.[27] It drew up a set of standards to prevent accidental problems and to guard against intentional ones. These “Asilomar guidelines” have been continually updated, and some of their principles are now baked into legal regulations governing the biotechnology industry.[28] There have also been efforts to create a rapid response system to counteract a suddenly emerging biological virus, whether released accidentally or intentionally.[29] Before COVID-19, perhaps the most notable effort to improve epidemic reaction times was the US government’s June 2015 establishment of the Global Rapid Response Team at the Centers for Disease Control.

Genentech: The Beginnings of Biotech
by Sally Smith Hughes

Recombinant DNA felt to him “like important stuff,” important enough to build a company upon.21 His seven years in venture capital had provided valuable training in raising money and advising new companies, but the experience had also made him feel “like a coach on the sidelines.”22 He wanted a piece of the action; he wanted a company of his own. Culling names from publicity on the 1975 Asilomar conference on recombinant DNA, he drew up a list of scientists prominent in the field. Swanson began to cold-call the scientists, asking if they thought the technology was ready to commercialize. Without exception, all believed recombinant DNA had industrial promise but surmised it would require a decade or two of development before a commercial payoff.23 Persisting despite the rebuffs, Swanson called Boyer, oblivious of the fact that he was contacting an inventor of the technology.

The Coming Wave: Technology, Power, and the Twenty-First Century's Greatest Dilemma
by Mustafa Suleyman
Published 4 Sep 2023

He’d begun to worry about what his invention might unleash and wanted to set some ground rules and moral foundations for going forward. At the Asilomar conference center, they asked the difficult questions thrown up by this new discipline: Should we start genetically engineering humans? If so, what traits might be permissible? Two years later they returned in even larger numbers for the Asilomar Conference on Recombinant DNA. The stakes in that sea-lapped hotel were high. It was a turning point in the biosciences, establishing durable principles for governing genetic research and technology that set guidelines and moral limits on what experiments could take place. I attended a conference in Puerto Rico in 2015 that aimed to do something similar for AI.

And they can spend time working with policymakers to ensure national and international regulations are scientifically and technologically sound.54 A good example of successful governance is the Montreal Protocol, which set a timetable to phase out the chemicals that were depleting the ozone layer. It involved rapid and extensive collaboration between scientists, industry leaders and policymakers, leading to what Kofi Annan called “perhaps the single most successful international agreement to date.”55 Another example is the Asilomar Conference on Recombinant DNA, in which leading scientists in the field considered the new dangerous possibilities their work had opened up. In response they designed new safety requirements on further work and restricted some lines of development completely.56 An interesting, and neglected, area of technology governance is differential technological development.57 While it may be too difficult to prevent the development of a risky technology, we may be able to reduce existential risk by speeding up the development of protective technologies relative to dangerous ones.

But he loved science—he read Scientific American cover to cover most months—he needed a job, and he had plenty of time with little to lose. So between cheap meals on the Ping-Pong table that also served as his desk and dining table at home, he cold-called scientists who had attended the Asilomar conference on recombinant DNA almost a year earlier. “I’m a businessman interested in recombinant DNA,” he would begin. Could he ask them a few questions? Some researchers said no. Others offered vague answers to the questions that Swanson considered essential: How long until recombinant DNA could be commercialized?

Future Crimes: Everything Is Connected, Everyone Is Vulnerable and What We Can Do About It
by Marc Goodman
Published 24 Feb 2015

We can no longer neglect the public policy, legal, ethical, and social implications of the rapidly emerging technological tools we are developing; we are morally responsible for our inventions. There are good examples in history where we as a society have brought together expertise in anticipation of catastrophic risk before it occurred. One such case was the 1975 Asilomar Conference on Recombinant DNA, which was held at Asilomar State Beach in Monterey, California. The event gathered 140 biologists, lawyers, ethicists, and physicians to discuss the potential biohazards of emerging DNA technologies and drew up voluntary safety guidelines. As a result of the event, scientists agreed to stop experiments involving mixing the DNA from different organisms—research at the time that held the potential to have radical, poorly understood, and potentially disastrous consequences.
