#37 The Anti-Catastrophe League
2025/12/16
Tom Ough tells us about the Big Things that may end humanity - and what we can do and in some cases have done to prevent these. Did you know that if all the risks, the one that is most likely to end you is aging? What are we doing to stop aging? Tom is a journalist and writer who is currently Senior Editor at UnHerd, a London‑based online magazine of culture and opinion. After several years working at The Telegraph, he moved into research on global catastrophic risks and wrote a nonfiction book titled The Anti‑Catastrophe League about individuals and efforts to prevent humanity’s extinction, and he also co‑hosts the Anglofuturism podcast.
-- IN THIS EPISODE WE LEARN --
Why aging itself can be understood as a catastrophic risk, and what it would mean to treat it with the same seriousness as other existential threats.
What it would actually take to detect, deflect, or survive an asteroid impact.
Why space expansion and Mars are a part of long-term civilizational resilience.
Why some catastrophic risks may be overestimated, and how to think more clearly about climate change relative to other existential threats.
What we know about super-volcanoes, why they’re rare but devastating, and why preparedness matters despite uncertainty.
How nuclear war remains a central catastrophic risk, and why deterrence, miscalculation, and escalation still deserve serious attention.
How to think about AI risk, what distinguishes it from past technological threats, and why uncertainty makes governance difficult.
What p(doom) means, why people disagree so strongly about it, and how probabilities shape policy and public discourse.
Who typically gravitates toward anti-catastrophe thinking, and what motivates people to focus on low-probability, high-impact risks.
What Anglo-futurism is.

#36 How crypto is sparking a longevity frenzy
2025/12/02
Today we’re diving into one of the strangest and most ambitious ideas in longevity: using crypto trading to fund real-time lifespan experiments.
Benji Leibowitz, founder of pump.science, joins us to explain how decentralized science works, why tokens can finance studies in worms, flies and mice, and what happens when a single post on X suddenly turns Metformin into a viral experiment. That intervention, by the way, is being spearheaded by LEVITY friend Linus Petersson, founder of the Swedish Longevity Cluster, who also joins the discussion.
In this episode we announce our new collaboration with pump.science. For now, that means they’ll contribute written content to the LEVITY newsletter - and later we may explore a dedicated Youtube format together.
More info here: https://reachlevity.com/p/desci-is-exploding-we-re-partnering-with-pump-science-to-help-you-follow-it
And check out pump.science's first post here: https://reachlevity.com/p/the-most-radical-idea-in-longevity-right-now
Key highlights in this episode:
– How pump.science turns attention and trading volume into funding for worm, fly, and mouse experiments.
– Why decentralized science emerged, and what problems in traditional science it tries to fix.
– What tokens, smart contracts, and DAOs actually mean in practice.
– Why Solana, not Ethereum, underpins the system.
– How real-time experimental data (like fly racing) could change how we evaluate longevity interventions.

#35 The Anti-Aging Uprising: Felix Werth’s Political Attack on Death Itself
2025/11/11
Valuable time is being lost because there is not enough funding for science with real life-extending potential. No major political party is promising to address aging, even though aging harms and kills more people than anything else. Most people—and most leaders—still do not understand that aging is both a problem and something that can be solved through science. We need a political movement that demands action and insists that something be done to save our lives.
And this is where this episode's guest comes in.
Felix Werth is the founder and chairman of the German Party for Rejuvenation Research — a political movement dedicated to accelerating scientific progress in regenerative medicine and longevity. Originally trained in biochemistry, Werth founded the party in 2015 (then called the Party for Health Research) to push for greater public investment in research aimed at combating aging-related diseases. Through his activism, Werth has helped bring the topic of longevity and healthy life extension into the political conversation in Germany and across Europe.

#34 Biomarkers of aging: How close are we, really? - A conversation with Sara Hägg
2025/10/28
Sara Hägg, PhD is an associate professor at Karolinska Institutet, where she leads the Molecular Epidemiology of Aging Group. Her work focuses on human biomarkers of aging - especially biological age “clocks” built from epigenetic, proteomic, and metabolomic data - and on turning Nordic registry resources into clinically useful aging measures.
In this episode:
* What biological/epigenetic age clocks actually measure (and what they don’t)
* Accuracy, error bars, and why clocks aren’t clinic-ready yet
* Epigenetic vs. proteomic vs. metabolomic clocks - strengths and trade-offs
* Organ-specific clocks (liver, ovary, kidney) and what they reveal
* Why uncertainty spikes at life transitions; menopause as a natural “stress test”
* PC (principal-component) clocks and noise reduction
* Nordic registry & Swedish Twin Registry advantages; UK Biobank use
* Direct-to-consumer tests: interpreting results and common pitfalls
* AI’s role in building/validating clocks and handling uncertainty
* What would move the field fastest (data, standards, trials) and where Sweden stands

#33 “Can death be the answer?" A conversation with philosopher Nicholas Agar
2025/10/07
We are always excited about the next technological solution. But what if it does not come? Or what if it comes only for the few, or with terrible side-effects? And while we are waiting for the easy tech fix, are we neglecting what we can do now to better our lives?
Many of our previous guests have been excited about the prospect of radically extending our lives, and some have been optimistic about the prospect of achieving this in our life time, perhaps even within a few decades. We are Levity, the real longevity podcast after all.
Todays guest thinks that we should be less excited about radical longevity, and radical enhancements in general. And he does not think radical life extension is on the horizon.
Nicholas Agar is a New Zealand philosopher specializing in ethics. He holds a BA from the University of Auckland, an MA from Victoria University of Wellington, and a PhD from the Australian National University. As of 2022, he is a Professor of Ethics at the University of Waikato. He is a prolific writer and the author of How to think about Progress, and Truly Human Progress, to mention two recent books.

#32 “Medical malpractice”: Matt Kaeberlein on biological age tests
2025/09/23
One idea I’ve had lately is to put together a list of people to trust in geroscience and the longevity field more broadly. (And I might do it - keep an eye on reachlevity.com
- and subscribe while you’re at it!)
Matt Kaeberlein would not only make that list - he’d likely be right at the top. He’s rigorous, precise in his wording, and always puts integrity ahead of hype. But, and this is important, I wouldn’t characterize him as a skeptic. He’s a realist who insists on evidence, yet at the same time he’s visionary and deeply optimistic about what aging science can deliver.
Matt is probably best known for his pioneering work on rapamycin and for co-founding the Dog Aging Project. In this episode, though, we also talk about Optispan - his proactive healthcare company - and Ora Biomedical, where the WormBot platform is screening thousands of interventions for effects on lifespan. We get into therapeutic plasma exchange (TPE), how artificial intelligence might accelerate discovery, and even his favorite science fiction books.
And true to form, Matt doesn’t hold back. He calls out irresponsible use of biological age tests - going so far as to label it “medical malpractice” - and criticizes hype-driven actors, sloppy science communication, and the inertia of institutions like the NIH. At the same time, he shows how rigorous, honest work could move the entire field forward.

# 31 He wants to save your pet with cryo - The Kai Micah Mills interview
2025/09/09
When you give a child a pet, you also expose them to death—since most pets pass away long before their owners. But what if we could cryopreserve Buddy or Tiger, and bring them back from suspended animation once we have a cure for what ended their lives?
Kai Micah Mills is a pioneering figure in radical life extension and biostasis. As the founder of Cryopets, he is leading efforts to make cryopreservation accessible for pets, with aspirations to extend these technologies to humans. He left high school early to pursue entrepreneurship, becoming a tech entrepreneur in his teens. A Thiel Fellow and co-founder of CryoDAO and HydraDAO, Kai is deeply involved in decentralized science initiatives aimed at advancing longevity research.

#30 Soon you'll take a drug designed by AI | Alex Zhavoronkov
2025/08/26
As you may have heard, AI-designed medicines have crossed a historic line. In this episode, Alex Zhavoronkov - CEO of Insilico Medicine and founder of ARDD walks us through how Insilico’s rentosertib became the first AI-generated small molecule with peer-reviewed clinical efficacy, while arguing against AI hype and reminding us that biology still moves at “the speed of traffic.” That duality runs through the whole conversation. On one side: a pragmatic operator obsessed with credible science, biomarkers, and clinical benchmarks; on the other: an AI visionary investing in cryonics, sketching “pharmaceutical superintelligence,” and thinking in decades, not quarters.
We start in Basel, home to Roche and Novartis, where ARDD was born, then trace how the conference morphed into a ”high-signal filter for longevity” - packed with startups (who also fund it), hard data, and mainstream pharma.
Alex looks back at his 2014 Nvidia talk (”Can Nvidia solve aging?”) and explains why Insilico trains its AI to learn age first - so it actually grasps biology. Years of problem-solving with pharma turned into their Pharma.AI toolkit (Biology42, Chemistry42, Medicine42, Science42).
Insilico now runs 40+ programs and in an early Phase 2 study for idiopathic pulmonary fibrosis (IPF), their drug rentosertib showed a dose-dependent boost in lung capacity.
Compared with the old path - often $150–200M and ~5 years just to pick a lead molecule - Insilico says it can often reach that point for under $3M or even less. Still, Alex is cautious: no matter how smart the AI gets, real-world testing and regulation won’t speed up overnight.
Also in this episode:
What made Alex cry.
Why he wouldn’t give his own drug to patients - yet.
How a mirror on a conference poster led to a proposal.
How ARDD became the “WEF of longevity”.
Why internal “kill teams” try to stop their own drug candidates.
Why labeling aging a disease helps - but won’t shortcut approvals.
Why he writes to “feed AI”.
How Nvidia threads through the story - from free GPUs to Jensen’s video.

#28 These rats don't age - here's why | Prof. Rochelle Buffenstein
2025/07/15
Even though it’s undeniably...aesthetic-challenged, the naked mole-rat is the envy of the longevity world. Its risk of death barely changes with time; it shrugs off cancer, stays fertile for decades and seems to skip every hallmark of aging that hobbles the rest of us.
But why? What evolutionary forces gave a mouse-sized, subterranean rodent near-immunity to aging - and what can its biology teach us about extending healthy human life?
Comparative biologist Prof. Rochelle Buffenstein (University of Illinois Chicago) - who has maintained the world’s largest captive colonies and authored 200+ papers - joins LEVITY to dissect the evidence.
In this episode
✅ Rochelle’s journey: from Zimbabwe farm kid to the pre-eminent naked mole-rat researcher.
✅ Eusocial society: queens, worker castes and lethal succession battles.
✅ No Gompertz slope: hard numbers that show mortality risk stays essentially flat for 40 years.
✅ Cancer resistance → high-molecular-weight hyaluronan, unusual immune cell profiles.
✅ Telomere maintenance and DNA-methylation reversal.
✅ Proteostasis on easy-mode: slow translation, durable proteins, super-charged autophagy.
✅ What actually kills a mole-rat?
✅ Translational angles: small-molecule screens, CRISPR edits, and why funding is still an uphill battle.
✅ Other long-lived species worth studying - and how young scientists can break into comparative gerontology.

#27 The mind-blowing science to bring you back from death - neuroscientist Ariel Zeleznikow‑Johnston
2025/07/01
When is someone really dead? What does it mean to survive? Is mind-uploading really a possible future way of surviving? These are some of the questions we are discussing with Dr Ariel Zeleznikow-Johnston.
Dr Ariel Zeleznikow‑Johnston is a neuroscientist and Research Fellow at Monash University in Melbourne, Australia, whose work delves into the neural basis of consciousness - from understanding how genetics and environment shape cognition to exploring the subtle qualities of perceptual experience such as color qualia. A 2019 PhD graduate from The University of Melbourne, he has published extensively on how cognitive function changes across the lifespan.
He is the author of The Future Loves You: How and Why We Should Abolish Death, which advocates for brain preservation technology as a means to suspend death and revive individuals in the future.
Check out Peter's review of the book here: https://reachlevity.com/p/a-clear-case-for-cryonics-a-review-of-the-future-loves-you
His multidisciplinary approach combines rigorous neuroscience with philosophy and ethics, positioning him at the forefront of contemporary debates about identity, mortality, and the future of human life.
🔍 In this conversation:
✅ When do we consider someone to be dead?
✅ What is vitrifixation?
✅ Cryonics.
✅ Palliative philosophy.
✅ Personal identity and the connectome.
✅ Are neurons the same over time?
✅ Teleportation as a test of the information view of personhood.
✅ How do we make the future love us?
✅ Survival and medical priorities.

#26 Inside Shift Bioscience’s single-gene rejuvenation breakthrough — Exclusive with CEO Daniel Ives
2025/06/17
Just about the hottest thing in longevity science right now is partial reprogramming - using Yamanaka factors to rewind the biological clock in our cells. Billion-dollar giants like Altos, Retro and New Limit are betting on it.
But in this episode a far smaller player, Shift Bioscience, argues that the field may be looking in the wrong place. CEO Daniel Ives explains how his team used AI-powered virtual cells to uncover a single gene that seems to match OSK-level rejuvenation without the tumor risk that haunts classical reprogramming - and why their just-released data could change the game for aging research.
🔍 In this conversation
✅ Daniel’s journey from mitochondrial PhD work to founding Shift Bioscience.
✅ Why Yamanaka-factor–based partial reprogramming excites the field and why it’s inherently risky.
✅ Epigenetic clocks 101 — Horvath, single-cell versions, and what they really measure.
✅ Building AI “virtual cells” (transformers / GNNs) to run millions of in-silico experiments.
✅ Discovery of new rejuvenation factor sets - including SB000, a lone gene that rejuvenates without inducing pluripotency.
✅ Early wet-lab validation across fibroblasts & keratinocytes; next-step mouse studies already under way.
✅ How inhibition targets (not just over-expression) could slash timelines from 15 years to ~5 years.
✅ Mapping a “risk landscape” of age-linked diseases and why fibrosis may be the fastest clinical entry point.
✅ Funding Shift: from personal redundancy money to a $16 M seed and the next raise.
✅ Timelines, escape-velocity hopes, and where cryonics still fits.
✅ What Daniel would ask Jeff Bezos, and why the pharma ecosystem needs to “plug in” now.

#25 What exactly is so bad about death?
2025/06/03
We think that death is bad, but why exactly is it bad? We cannot suffer when we do not exist, so why would it be bad?
In this episode we have a long, deep conversation with Professor Travis Timmerman, whose philosophical work delves deeply into the nature and ethics of death. An Associate Professor at Seton Hall University, Professor Timmerman has become a prominent voice in contemporary discussions about whether death is bad for us, how we should understand the harm of dying, and what moral obligations we might have surrounding death and dying. His work engages both timeless questions and urgent contemporary debates—offering fresh insight into topics like the timing of death’s harms, the ethics of procreation, and our attitudes toward mortality.
What you'll learn in this episode:
✅ Why death is bad
✅ How it can bad to not have been born earlier
✅ What the ancient Mirror Argument gets wrong
✅ How it can be bad for a 95-year-old to die
✅ Whether we should wait to have children
✅ How an analytical philosopher thinks about death

#24 Dr. Valter Longo - The BIG 2025 interview
2025/05/20
There were two reasons why Dr. Valter Longo was featured so prominently in my longevity book Evigt Ung (2022).
First, if you had to name a single scientific thread running through the history of longevity research, calorie restriction is hard to beat. And few have done more to modernize and translate that insight into real-world practice than Longo.
Second, I hold Valter Longo in the highest regard. I've tried his Fasting-Mimicking Diet (FMD), I’ve followed his work on The Longevity Diet, and I find his scientific contributions both rigorous and unusually translational. He doesn’t just publish papers - he builds systems, tests interventions in clinical trials, and tries to implement science into healthcare.
In this conversation, we cover the science, history, and application of fasting, nutrition, and longevity - including new work on cancer, metabolism, and organ regeneration. We also discuss the philosophical and political obstacles that stand in the way of real change.
What you'll learn in this episode:
✅ The story of Longo’s early music career - and why he left it to study aging.
✅ How calorie restriction shaped modern longevity science.
✅ Why Biosphere 2 and Roy Walford's work was both inspiring and cautionary.
✅ The origins and mechanisms of the Fasting-Mimicking Diet.
✅ What Longo learned about autophagy, stem cells, and organ regeneration.
✅ Why protein intake before and after age 65 should be treated differently.
✅ What the media and doctors get wrong about obesity, food, and metabolism.
✅ The dangers of high-protein and ketogenic diets.
✅ Why Longo is deeply skeptical of TRT, growth hormone, and biohacking shortcuts.
✅ How fasting can enhance cancer treatment - and why Longo wrote his new book Fasting Cancer.
✅ Why we need a new kind of “digital school” for lifestyle medicine.
