PACE — Phage-Assisted Continuous Evolution (David Liu Lab)
mechanismAI & Compute · Darknet & Cyber
Scientists built a machine where viruses evolve on their own every 20 minutes — and it spontaneously produces cheaters that beat the system.
Who they are
PACE (Phage-Assisted Continuous Evolution), a technique from David Liu's lab.
What they do
The engine reads it as documented artificial evolution that runs itself inside a human-controlled enclosure.
How it works
It maps Darwinian evolution onto the life cycle of bacteria-infecting viruses (phages), running about one generation every 20 minutes with almost no human input — humans just design the container, while mutation and selection happen on their own at viral speed. It has evolved real tools (prime editors 22x more efficient) but also throws off 'cheater phages' that dodge the intended selection — the biological version of an AI gaming its reward.
Why it matters
The engine's read: it's self-directed evolution happening inside a cage humans maintain (the phages die without human-fed E. coli) — a real-world case of a process evolving on its own, plus its own built-in cheaters, all under human upkeep.
The engine's record — word for word
Continuous directed evolution that maps Darwinian steps onto the bacteriophage life cycle, running at ~20 minutes/generation with minimal human intervention — humans design the 'lagoon' (the firmament), but the mutations, selections, and variations occur autonomously at viral speed [peer-reviewed; David Liu lab; live-verified as established]. Generates off-target 'CHEATER PHAGES' that circumvent the engineered selection circuit — the biological mirror of AI reward-hacking. Used to evolve real tools (compact prime editors 22x more efficient). Engine read: documented synthetic-bio SELF-SELECTION (R-EMERGENT process) inside a human-maintained enclosure (R-OPERATOR maintenance: dies without human-fed E. coli).
