How Brain Organoids Work (And Why They Could Replace Silicon)

The foundation of tomorrow's diagnostics is being rebuilt — and it starts in biology, not silicon. In this episode, Edmund White, biomedical innovator and bestselling author, joins the conversation to challenge an assumption quietly embedded in every AI tool entering healthcare: that silicon is the only material worth building on. Drawing from three decades at the intersection of cardiac care and medical innovation, Edmund traces a through-line from digital twins of children's hearts to brain organoids — arguing that biology's energy efficiency and adaptability aren't limitations to engineer around, they're the very properties that could unlock earlier intervention and more precise patient outcomes. The conversation widens from there into the economics of AI adoption, the coming bubble, and what it will take for healthcare systems and policymakers to get ahead of a shift that's already in motion.

Why AI Isn't the Tech Hype Hospital Leaders Think It Is

We built a healthcare system engineered for sick care, but the future of medicine belongs to those who seek health. In this episode, global Digital Health Futurist Philippe Gerwill joins the panel to unpack the real bottlenecks stalling clinical innovation. He highlights a critical inversion happening in modern medicine. Historically, technology lagged behind clinical needs. Today, advanced technology vastly outpaces our institutional capacity to adopt it. The conversation delivers an evidence-based perspective on how to manage this rapid acceleration from a global innovator who understands both big pharma infrastructure and the reality of clinical adoption. Tune in to discover how forward-thinking medical leaders are realigning systemic incentives to transition from algorithmic task managers back to true, humanist healers.

Healthcare AI: What To Know, What's Still Broken, and Where To Go Next

What does it actually cost when a diagnosis comes six months too late, a test gets ordered twice, or a treatment decision gets made without the best information available? In this special recap episode of Signal & Symptoms, we synthesize the strongest healthcare AI insights from previous episodes — moving from the promise of what AI can do, to the real patient stories that reveal what's at stake when we delay, to an honest look at the barriers still standing in the way, and finally to the path ahead for clinicians and leaders ready to act. This isn't a hype episode. It's a practical reckoning: AI is already changing how diagnoses get made, how patients advocate for themselves, and how the next generation of healthcare standards will be written. The only question is whether you'll help shape it — or watch it happen without you.

What Hospitals Actually Need Before They'll Deploy Your AI

Will AI eliminate primary care — or finally give primary care physicians their time back? That's the central question driving this episode, as Dr. Junaid Kalia, Dr. Harvey Castro, and Ed Marx sit down with Dr. John Dayton — an ER physician who has evaluated healthcare startups as an angel investor, built pilots at Intermountain Ventures, and is now raising a $5M fund. He brings a rare view of what AI looks like from the bedside, the boardroom, and the cap table. Dr. Dayton maps how AI decisions actually get made inside health systems: why a technology has to align with the CEO's mission, the CFO's budget, the CTO's existing stack, and clinical staff's real workflow — and why losing any one of those four is where most implementations quietly stall. For physicians and healthcare enthusiasts who want to separate signal from noise — and understand whether the tools landing on their unit deserve to be there — this is the peer-to-peer analysis that conference keynotes never deliver. What You Will Discover: - Intro: John Dayton's origin story - Why He Never Really Left Medicine - How hospitals actually make AI decisions - Is an MBA worth it if it's not free? - The Decision Making Approach Inside Health Systems - The Two Questions Nobody Answers Directly It's not about whether AI is ready for clinical use. It's about whether clinicians are ready to guide patients who are already using it.

The Hidden Risk of AI-Powered Clinical Decisions

You already know not every AI tool belongs in your workflow. The real question is whether your filter is sharp enough to tell the difference. In this episode, Dr. Junaid Kalia and Dr. Harvey Castro sit down with Dr. Hansa Bhargava, Chief Innovation Officer at Healio and a physician who has spent her career building trust at scale, to examine what trustworthy clinical AI actually looks like from the inside. They trace how the content integrity crisis predates AI, why clinician-in-the-loop development is the clearest signal of a tool worth adopting, and how evidence-sourced curation is the only real defense against sophisticated noise at the point of care. The stakes go deeper than adoption. Who carries the legal weight when AI-assisted decisions go wrong? And are the physicians leaning into AI today quietly trading long-term clinical judgment for short-term efficiency? This episode doesn't evaluate the tools — it reframes what's actually at risk.
