Where to work: fellowships, institutes, and careers

Last September, scientists used an AI model to design genomes for entirely new bacteriophages (viruses that infect bacteria). They then built them in a lab. Many were viable. And despite being entirely novel some even outperformed existing viruses from that family.

That alone is remarkable. But as today's guest — Dr Richard Moulange, one of the world's top experts on 'AI–Biosecurity' — explains, it's just one of many data points showing how AI is dissolving the barriers that have historically kept biological weapons out of reach.

For years, experts have reassured us that 'tacit knowledge' — the hands-on, hard-to-Google lab skills needed to work with dangerous pathogens — would prevent bad actors from weaponising biology. So far, they've been right.

But as of 2025 that reassurance is crumbling. The Virology Capabilities Test measures exactly this kind of troubleshooting expertise, and finds that modern AI models crushed top human virologists even in their self-declared area of greatest specialisation and expertise — 45% to 22%.

Meanwhile, Anthropic’s research shows PhD-level biologists getting meaningfully better at weapons-relevant tasks with AI assistance — with the effect growing with each new model generation.

Richard joins host Rob Wiblin to discuss all that plus:

• What AI biology tools already exist
• Why mid-tier actors (not amateurs) are the ones getting the most dangerous boost
• The three main categories of defence we can pursue
• Whether there’s a plausible path to a world where engineered pandemics become a thing of the past
