  • Awesome podcast

    After listening to the AI podcast and going over like AI etiquette and how adults and kids interact with AI, I found it very enlightening, but also humoristic at the same time due to the fact that I couldn’t stop thinking of hot tub Time Machine to the movie when the guy was rude to the auto drive car cab and the cab ended up filing a complaint and ended up wanting to terminate thus human for being rude and mean to the car and violent at the same time so yeah AI etiquette and the future of AI en... more

  • Fascinating topics & real science

    This is so necessary these days. I started following Eric Topol when Covid started and I am so glad I did. The information he freely shared with the public probably saved my life (I am still a novid here at the end of 2025) and today’s episode with Dr. Gunter couldn’t have come at a better time. I have been fighting for MHT for more than a year now & hot flashes are currently killing me. Now I can take some of this information in to my next appointment. Thank you both!!

Talking Points

Recent interactions between the hosts and their guests.

Vadim Gladyshev and the Science of Aging
Q: You think, ultimately, we're gonna have a substantial way to reverse the biological aging, not, you know, aging per se, but the associated changes. You think this is likely in the years ahead?
Gladyshev says biological age is partially reversible, citing parabiosis, embryonic rejuvenation and treatments that address disease-related changes. He distinguishes this from aging itself, which he considers irreversible.
Vadim Gladyshev and the Science of Aging
Q: Can you take us through the different clocks that you've worked on, because they don't seem to measure the same thing?
Different clocks measure different features, such as chronological age, function or mortality, and use distinct data modalities. Combining measures such as proteomics, wearables, imaging, photos and voice can provide a broader view, while organ-specific mortality clocks can help predict diseases affecting those organs.
Michael Lewis: The NIH “Murder Mystery,” DOGE, and Our Government Immune System
Q: What inspired you to frame the story as a murder mystery, and who did you consider as the prime suspect?
Lewis explains that the motive was to personify the tensions within federal funding for science, with suspects including figures close to the policy machinery; he emphasizes that the mystery format helps readers grasp the stakes and actors who shaped science policy under the Trump administration.
Aaron Newman: A Breakthrough Blood Test for Cancer
Q: What evidence supports the clinical relevance of the liquid biopsy approach in melanoma?
A cohort of pre-treatment melanoma patients showed strong correlations between blood ecotypes and tissue-based responses to immunotherapy, validating the prognostic value.
Aaron Newman: A Breakthrough Blood Test for Cancer
Q: How does the Liquid Ecotyper translate tissue findings into a blood test?
By mapping tissue ecotype signals to DNA methylation patterns in cell-free DNA and applying AI to extract the corresponding ecotype probabilities in blood, enabling noninvasive monitoring.
