Ideas: More AI-resilient biosecurity with the Paraphrase Project

Now, let’s rewind two years. Almost to the day, Bruce and I uncovered a vulnerability. While preparing a case study for a workshop on AI and biosecurity, we discovered that open-source AI protein design tools could be used to redesign toxic proteins in ways that could bypass biosecurity screening systems, systems set up to identify incoming orders of concern.  Now in that work, we created an AI pipeline from open-source tools that could essentially “paraphrase” the amino acid sequences—reformulating them while working to preserve their structure and potentially their function.  These […]

When AI Meets Biology: Promise, Risk, and Responsibility

Advances in AI are opening extraordinary frontiers in biology. AI-assisted protein engineering holds the promise of new medicines, materials, and breakthroughs in scientific understandings. Yet these same technologies also introduce biosecurity risks and may lower barriers to designing harmful toxins or pathogens. This “dual-use” potential, where the same knowledge can be harnessed for good or misuse to cause harm, poses a critical dilemma for modern science. Great Promise—and Potential Threat I’m excited about the potential for AI-assisted protein design to […]
