Biologists at Stanford University have achieved a significant breakthrough in synthetic biology by employing artificial intelligence to create a complete genetic blueprint of a virus, named Evo-Φ2147, designed to target and destroy harmful bacteria, specifically E. coli. This milestone, reported in September, marks a transformative moment in the field, illustrating that AI can now draft entire genomes rather than merely editing existing genetic sequences.
The researchers successfully synthesized Evo-Φ2147 in laboratory conditions, watching as it effectively attacked E. coli bacteria, evidenced by clear patches of bacterial destruction on petri dishes. This demonstration highlights a fundamental shift in how scientists can approach genetic design, moving from a traditional, Darwinian model of evolution to what British molecular biologist and tech entrepreneur Adrian Woolfson describes as a “post-Darwinian landscape,” where life can be intentionally authored.
Woolfson characterized the accomplishment as “a massive, consequential moment,” underscoring the profound implications of being able to construct life forms from the ground up. He noted, “For the last four billion years evolution has been blind—there has been no foresight, there has been no intentionality. This is not speculation. It’s not futuristic; it is happening.”
The new virus is composed of just 11 genes encoded within 5,386 base pairs of DNA, significantly smaller than the human genome, which contains around 20,000 genes distributed across 3.2 billion base pairs. Woolfson emphasized that this breakthrough enables the creation of life in a rudimentary way and marks the beginning of a new era in genetic engineering.
While most scientists do not classify viruses as truly alive due to their dependency on hosts for replication, the experiment showcases the potential to author entire genomes, rather than simply modify existing ones. Complementing this advance, researchers at the California Institute of Technology have introduced a DNA construction tool, Sidewinder, which can assemble lengthy genetic sequences with precision up to 100,000 times greater than previous methods, making the process faster and more cost-effective.
Woolfson’s new venture, Genyro, has attracted some of the leading minds in the field of genetic design, including Brian Hie, the Stanford scientist behind the AI breakthrough, and Caltech researchers Kaihang Wang and Noah Robinson. Wang expressed that controlling the “source code of life” opens up limitless possibilities, stating, “If you can control the source code of life, you can create anything and everything. The only thing limiting it is our imagination.”
Industry figures are already recognizing the implications of this technology. Bob Langer, a co-founder of vaccine manufacturer Moderna and an adviser to Genyro, referred to the technology as a “remarkable advance.” He highlighted the potential for utilizing AI to select DNA constructs that could lead to new medicines, materials, and a wide array of applications.
This breakthrough opens new avenues for both synthetic biology and medicine, prompting discussions about the ethical implications and future applications of designing life at the genetic level. As research advances, the ability to create entirely new organisms could revolutionize how we approach health, agriculture, and biotechnology, paving the way for innovations that were previously considered the realm of science fiction.
