Bioterrorism and your brainBioterrorism and your brain
All In The Mind
Knowledge can be dangerous. As neuroscience delves more deeply into our organ of thought and its complex soup of neurotransmitters - could it also be exploited for malign purposes? Is the brain the next target of terrorism? Pharmaceutically enhanced soldiers, chemical torture, incapacitants, neurological weaponry... The possibilities are frightening and progress rapid. Two leading researchers into biological weapons present their concerns, and argue scientists need to take action now. But are we at risk of paranoia?

Bioterrorism, Brain Science and the Battle Over Chemical Control
Episode Overview
- Rapid advances in neuroscience and life sciences create realistic opportunities for hostile applications, not just medical treatments.
- Historical use of nerve agents, BZ and psychoactive compounds shows long-standing military interest in targeting the nervous system.
- The 2002 Moscow theatre siege provides evidence of a state developing and using a fentanyl-based incapacitating agent, setting a worrying precedent.
- International conventions contain ambiguities around law enforcement chemicals, leaving loopholes for developing and deploying new agents.
- Biologists and neuroscientists are urged to engage in ethics and policy, aiming to restrict malign uses while preserving therapeutic benefits.
“The challenge is to prevent that science, which is the same science, from being misused, while retaining our ability to enjoy its benefits.”
This episode dives deep into the challenges and risks posed by modern neuroscience when it intersects with military ambition and bioterrorism. You’ll hear a calm but unsettling conversation about how rapidly growing knowledge of the brain’s chemistry could be turned towards hostile uses, from incapacitating crowds to manipulating memory, fear, and even trust.
Host Natasha Mitchell chats with microbiologist Dr Mark Wheelis and Professor of International Security Malcolm Dando, who explain why the "huge revolution" in the life sciences won’t automatically stay on the side of good. They walk through historical attempts to weaponise the nervous system, including nerve agents like sarin and non‑lethal chemicals such as BZ, and then connect those examples to today’s far more sophisticated understanding of neuroreceptors and brain circuits.
One of the most striking case studies is the 2002 Moscow theatre siege, where an anaesthetic based on the opiate derivative fentanyl was pumped through the ventilation system to knock out hostage-takers and hostages alike. As Wheelis notes, this is "virtually definitive evidence" that a state developed, stockpiled and used a psychoactive incapacitating agent, raising fears that others might follow.
The trio talk through ethical minefields: using oxytocin to make detainees more trusting, chemicals that induce extreme depression or panic as tools of interrogation, and the broader issue of manipulating human physiology without consent. At the same time, they stress that the very same science holds huge promise for treating mental illness and neurological disease, which means shutting it down isn’t an option. Both guests argue that scientists themselves need to step up.
Referring to past activism against biological warfare, they call for neuroscientists, immunologists and other life scientists to get involved in policy and help limit malign uses while protecting therapeutic progress. If you’ve ever wondered how far brain science might go when mixed with politics and conflict, this conversation will make you think hard about where the line should be drawn. What responsibility do you think researchers should carry as their work reshapes both medicine and security?
