- 34 minutes 18 secondsBrain Organoids: from Space to AI with Alysson Muotri
Professor Alysson R. Muotri (geneticist and developmental biologist at UC San Diego) joins for a far out conversation about sending brain organoids to the International Space Station and what they're teaching us about aging, neurological disease, and a new kind of AI. One month in orbit ages an organoid the equivalent of 10 years on Earth, and Alysson's lab has already used that compressed timeline to unlock an FDA-approved clinical trial for a drug developed in space.
In this episode, we discuss:
- Why space accelerates brain aging
- The surprising role of "junk DNA" and endogenous retroviruses in neuroinflammation and neurodegeneration
- Why HIV antiretroviral drugs may be the key to treating neurological conditions
- What the decommissioning of the ISS and the rise of commercial space stations mean for biomedical research
- How brain organoids learn, remember, and inspire a new generation of AI algorithms beyond transformers
- The bioethics frontier: when do organoids become conscious and how would we even know?

Jonathan Sporn (CEO + Founder of Gilgamesh Pharma) joins for a deep dive into next-gen psychedelic medicines, why duration matters for real-world clinical use, and what it takes to build these therapies the way large pharma would—culminating in a partnership with AbbVie worth up to $1.2B.
In this episode, we discuss:
• Why Gilgamesh is building psychedelic medicines the way large pharma would
• The thesis behind short-acting psychedelics and why long-duration trips are impractical for real-world psychiatry
• How Gilgamesh designs molecules backwards from clinical needs
• Effective approaches to the challenges of trial designs for psychedelics
• What AbbVie’s deal and Spravato’s trajectory mean for psychedelics
• How psychedelic medicines could reshape mental healthCredits:

Greg interviews Rick Perry, the former Governor of Texas and former U.S. Secretary of Energy and leading advocate for ibogaine, live at the Real Summit.
In this episode, we discuss:
- How a former Texas governor moved from strict opposition to drugs to becoming a leading advocate for ibogaine after firsthand experience and veteran outcomes.
- Ibogaine’s impact on PTSD, opioid addiction, and traumatic brain injury, including Stanford-linked brain imaging data showing functional and structural improvement.
- How veterans are the proving ground that enabled Texas to commit $50M in public funding for ibogaine clinical trials.
- Why ibogaine requires intensive medical supervision and why rigorous trials are essential for legitimacy and scale.
- A vision where ibogaine reshapes addiction treatment, veteran care, and eventually criminal justice and homelessness policy.

Matias interviews James (Jim) Gorman MD PhD from the Wyss Institute. Jim is Principal Investigator on the Wyss Institute Brain Targeting Program (BTP). Jim leads a team developing new approaches to transport drugs through the blood brain barrier (BBB) into the CNS.
In this episode, we discuss:
- Why the BBB blocks most modern drugs from entering the brain, creating the biggest bottleneck in neuro
- How brain shuttles hijack natural transport pathways like the transferrin receptor to move drugs across the BBB
- How new modalities that reach the brain can potentially treat diseases like Alzheimer’s, Parkinson’s, ALS, and lysosomal disorders
- Why delivery route of shuttles enable IV or subcutaneous dosing instead of invasive intrathecal injections
- How early data shows that shuttle-enabled antibodies clear amyloid faster, at lower doses, and with fewer side effects
- How the field is accelerating through a pre-competitive consortium model that lets multiple companies share shuttle platforms

Greg and Matias interview Luis Voloch, CEO and Co-Founder of Jimini Health, an AI behavioral health company. He previously co-founded and served as CTO of Immunai, where he applied machine learning to immunology and drug discovery.
In this episode, we discuss:
- How LLMs expand the scope of machine learning from rule-based tasks to open-ended reasoning and dialogue
- Why healthcare adoption is tiered, beginning with clinician-facing AI scribes and moving toward patient-facing companies with human-in-the-loop to enhance quality of care
- Why human oversight is essential and how AI can augment complex clinical work instead of replacing it
- The competitive advantage from workflows, data, and trust via purpose built AI systems
- The path toward precision psychiatry, where continuous, language-based interactions can generate rich behavioral data to inform diagnostics, treatment, and drug discovery
