    Ned David is the co-founder of Unity Biotechnology, a company developing senolytic medicines—molecules that target and destroy senescent cells in the human body. In this episode, Ned explains the science of cellular senescence and how it impacts the aging process. Ned discusses how senolytics may delay, prevent, treat, or even reverse age-related diseases, including cancer, cardiovascular disease, and neurodegenerative disease. As a serial entrepreneur, Ned also provides advice on how to transform a simple idea into the creation of a company.

    #110 - Lew Cantley, Ph.D.: Cancer metabolism, cancer therapies, and the discovery of PI3K

    #110 - Lew Cantley, Ph.D.: Cancer metabolism, cancer therapies, and the discovery of PI3K

    In this episode, Lew Cantley, Professor of cancer biology and Director of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medical College in NYC, walks us through his amazing discovery of phosphoinositide 3-kinase (PI3K) and the implications for the care of patients with cancer. He explains various combinations of therapies being tested and used, including the possibility of pairing prescriptive nutritional therapies to increase the efficacy of drugs like PI3K inhibitors. Lew also explains the metabolic nature of cancer through the lens of his research into the connection between sugar consumption, insulin resistance, and tumor growth. Additionally, Lew provides some details about his exciting new clinical trial that is just now enrolling patients with stage 4 breast cancer and endometrial cancer.

    #107 - John Barry: 1918 Spanish flu pandemic—historical account, parallels to today, and lessons

    #107 - John Barry: 1918 Spanish flu pandemic—historical account, parallels to today, and lessons

    n this episode, John Barry, historian and author of The Great Influenza: The Story of the Deadliest Pandemic in History, describes what happened with the 1918 Spanish flu pandemic, including where it likely originated, how and why it spread, and what may have accounted for the occurrence of three separate waves of the virus, each with different rates of infection and mortality. While the current coronavirus pandemic pales in comparison to the devastation of the Spanish flu, John highlights a number of parallels that can be drawn and lessons to be learned and applied going forward.

    We discuss:

    What got John interested in the Spanish flu and led to him writing his book? [2:45]; Historical account of the 1918 Spanish flu—origin, the first wave in the summer of 1918, the death rate, and how it compared to other pandemics [10:30]; Evidence that second wave in the fall of 1918 was a mutation of the same virus, and the immunity immunity protection for those exposed to the first wave [18:00]; What impact did World War I have on the spread and the propagation of a “second wave”? [21:45]; How the government’s response may have impacted the death toll [26:15]; Pathology of the Spanish flu, symptoms, time course, transmissibility, mortality, and how it compares to COVID-19 [29:30]; The deadly second wave—The story of Philadelphia and a government and media in cahoots to downplay the truth [35:50]; What role did social distancing and prior exposure to the first wave play in the differing mortality rates city to city? [44:45]; The importance of being truthful with the public—Is honesty the key to reducing fear and panic to bring a community together and combat the socially-isolating nature of pandemic? [46:15]; Third wave of Spanish flu in the spring of 1919 [51:30]; Global impact of Spanish flu, a high mortality in the younger population, and why India hit so much harder than other countries [55:15]; What happened to the economy and the mental psyche of the public in the years following the pandemic? [59:20]; Comparing the 2009 H1N1 virus to Spanish flu [1:02:10]; Comparing SARS-CoV-2 to the Spanish flu [1:04:20]; What are John’s thoughts on how our government and leaders have handled the current pandemic? [1:08:00]; Sweden’s herd immunity approach, and understanding case mortality rate vs. infection mortality rate [1:10:40]; What are some important lessons that we can apply going forward? [1:13:00]; Does John think we will be better prepared for this in the future? [1:16:00]; and More Learn more: https://peterattiamd.com/

Exceptional, without fail!

Peter is exceptionally articulate, I’m forever grateful for the time he puts into his podcasts, show notes and website.. I learn something new every time without fail I tune in, and I recommend whomever I talk to the latest podcast that I’ve just finished. Thank you Peter if you read these reviews!

My favourite podcast show

I’ve been following Peter Attia for many years and he’s one of the few communicators in the area of optimising human health and longevity that I truly trust and respect. If you’re scientifically minded and interested in increasing your lifespan and healthspan, this podcast is essential listening. Although my PhD is not in a related subject (I studied physics), I’ve spent a modest amount of time diving into related literature over past few years and given what I know, I think he asks excellent questions. Often the discussions get a bit technical but I personally enjoy the challenge and I always learn something new in each podcast; they’re incredibly informative.

Intellectual crush

This podcast is so intellectually stimulating I get a high listening to it and withdrawals when I don't.
