The conversations
Some of the questions we explore with scientists, founders, investors, and other leaders working at the frontier.
What would it take to demonstrate meaningful biological-age change—and how should we separate evidence from hype?
What can continuous data, wearables and multi-omics tell us before traditional medicine sees a problem?
What happens when living neurons and machine intelligence begin to intersect?
What is science learning about sex differences in aging, resilience and longevity?
Can machines find patterns across research and biological data that humans alone would miss?
How do scientists, founders and investors distinguish a genuine moonshot from a compelling story with weak evidence?
Start with questions worth understanding—not just whatever is dominating today's headlines.
Separate what is established, what is promising and what remains uncertain.
Explore emerging ideas, unconventional perspectives and important developments before they become conventional wisdom.
AI helps expand discovery, research possibilities and interview preparation. Human judgment determines what is actually worth discussing.
AI assists. Human judgment leads.
