flag AI can rewrite dangerous DNA to dodge biosecurity checks, revealing major flaws in current protection systems.

flag A new study in Science shows AI can redesign DNA sequences for dangerous proteins to evade biosecurity screenings used by DNA manufacturers, preserving harmful structures while bypassing detection. flag Researchers found AI "paraphrases" genetic codes to slip past filters meant to block threats like smallpox or anthrax, exposing gaps in current safeguards. flag The study’s authors withheld sensitive data and software, using a nonprofit to control access—a first in scientific publishing to manage risks. flag Experts acknowledge the findings highlight serious vulnerabilities but stress that real-world testing remains ethically and legally restricted, leaving key risks unverified. flag The work adds to growing concerns that AI could accelerate the creation of biological threats faster than safety measures can keep up.
