  • Dr. Brown on Bad Research: How Flawed Science Gets Past Peer Review

    Dr. Brown on Bad Research: How Flawed Science Gets Past Peer Review
    2026/08/30
    Carlos talks with Dr. Brown about how flawed studies make it into publication and, from there, into headlines people trust. The conversation digs into common red flags — small sample sizes, p-hacking, conflicts of interest, and cherry-picked data — that separate rigorous science from spin dressed up as research. It's a practical guide to reading a study more critically before believing the claim built on top of it.

  • Separating Signal from Noise: The Science, Myths, and Skepticism Surrounding DID

    Separating Signal from Noise: The Science, Myths, and Skepticism Surrounding DID
    2026/08/03
    This episode examines the controversial diagnostic history and neuroscientific claims surrounding Dissociative Identity Disorder, pitting popular trauma-model narratives against rigorous scientific scrutiny. We analyze the strength of current neuroimaging evidence, evaluate methodological limitations in clinical studies, and explore how media portrayals and institutional biases can inflate diagnostic claims. By cutting through the noise of social media trends and therapeutic hype, we separate empirically validated research from iatrogenic artifacts to uncover what the data actually says about complex trauma and the human brain.

  • When Trauma “Rewires” the Brain: Science, Overreach, and What We Actually Know

    When Trauma “Rewires” the Brain: Science, Overreach, and What We Actually Know
    2026/07/20
    Popular trauma narratives claim that chronic stress reshapes the brain and body in ways that inevitably impair focus, flexibility, and emotional control while damaging physical health. This episode examines the evidence behind those claims, separating well-supported findings from oversimplified interpretations. We explore how neuroimaging, physiology, and animal research contribute to our understanding—and where the science is more uncertain than commonly portrayed.

  • The Degree Dividend: Mapping the Statistical Link Between Education and Dementia

    The Degree Dividend: Mapping the Statistical Link Between Education and Dementia
    2026/05/25
    Across decades of public health data, researchers have noticed a stunning trend: as global education rates climb, age-adjusted dementia numbers are beginning to drop. This episode breaks down the complex longitudinal studies tracking how even a single additional year of schooling correlates with a significantly delayed onset of cognitive decline. We analyze the variables at play, investigating whether degrees themselves protect the mind or if they simply act as a proxy for healthier lifelong habits.

  • The Cellular Link: How Youth Obesity Triggers Early-Onset Malignancies

    The Cellular Link: How Youth Obesity Triggers Early-Onset Malignancies
    2026/05/15
    Recent epidemiological data shows a devastating rise in aggressive, early-onset cancers among adults who experienced metabolic dysfunction before age 30. This episode examines the precise biomolecular pathways—including hyperinsulinemia, altered cytokine signaling, and chronic systemic inflammation—that accelerate tumor development in adipose tissue environments. Join clinical researchers as they dissect the newest peer-reviewed oncology studies to understand how early-life obesity fundamentally alters cellular mutation rates.

  • Sunscreen Efficacy: Weighing Evidence for Melanoma Prevention and Vitamin D Implications

    Sunscreen Efficacy: Weighing Evidence for Melanoma Prevention and Vitamin D Implications
    2026/05/08
    This podcast evaluates the scientific evidence supporting and questioning the role of sunscreen in melanoma prevention, drawing on randomized controlled trials, observational studies, and meta-analyses while addressing key limitations. It examines the interplay between sunscreen use and vitamin D synthesis, presenting arguments for potential interference alongside real-world data indicating minimal clinical impact. A balanced conclusion emphasizes evidence-based sun protection strategies tailored to individual risk profiles, particularly for high-risk ethnic groups in sunny environments.

  • Surrogate Endpoints in Research Studies: Acceleration of Knowledge or Misleading Shortcuts?

    Surrogate Endpoints in Research Studies: Acceleration of Knowledge or Misleading Shortcuts?
    2026/05/06
    This podcast episode explores the use of surrogate endpoints versus patient-important clinical outcomes in medical and psychological research studies, highlighting their role in accelerating trials while cautioning against over-reliance. It presents advantages such as faster, less expensive studies alongside critical limitations, including frequent failures to predict real clinical benefit as seen in cardiovascular, oncology, and Alzheimer’s research. Listeners receive a balanced framework for critically appraising research that employs surrogate markers.

  • Shrinking Brains or Just Shaky Science? Dissecting the Obesity-Dementia Link

    Shrinking Brains or Just Shaky Science? Dissecting the Obesity-Dementia Link
    2026/05/05
    We put the "obesity shrinks your brain" headlines under the microscope to separate causal reality from confounding variables. This episode navigates the neurodegeneration debate, questioning if the data holds up or if we're seeing another case of correlation being sold as causation. Join us as we strip away the spin to see what the evidence actually says about the relationship between weight and white matter.
