Finding genes at scale for age reversal - Shift Bio CEO Daniel Ives
2026/02/03
Dr. Daniel Ives is the founder of Shift Bioscience. Shift has built a novel single-cell aging clock that has enabled them to run high-throughput screens to discover genes that regulate aging, with the goal of identifying a therapy to systemically reverse aging. We’ll dive deep into Shift’s latest work on SB000, a germline-expressed gene that rejuvenates cells without inducing pluripotency, and SB101, a pro-aging gene whose inhibition both reverses cellular age and prevents fibrosis, opening a clear path to clinical development. Daniel also shares his philosophy on why reversing aging might be easier than we think, the coming cultural shift when anti-aging drugs become mundane reality, and why he won't rest until we can double human lifespan.

NewLimit Co-Founder Jacob Kimmel on Reversing Aging with Predictive Biology
2026/01/13
Dr. Jacob Kimmel is the President of NewLimit, a biotechnology company developing reprogramming medicines to treat age-related disease and extend human healthspan. Dr. Kimmel co-founded the company with Blake Byers and Bryan Armstrong, and has since raised over $300M from top venture capital funds like Kleiner Perkins, Dimension, Founders Fund, and Khosla Ventures. They expect to initiate their first clinical trial in a few years. Dr. Kimmel has garnered a reputation as one of the brightest minds in longevity and the intersection between artificial intelligence and molecular biology, and NewLimit is often cited as one of the most important companies building in longevity today.
How a serial tech entrepreneur is fomenting a revolution to cure aging and death - Adam Gries
2025/12/16

He has now set his sights on creating a longevity revolution through his organization Vitalism. Vitalism is a moral philosophy and community of action, forming a revolutionary movement to get humanity to fight as hard as possible to achieve unlimited lifespans in peak health. Our conversation covers the state of the longevity field today, the myth of billionaires’ obsession with longevity, what it will take to revolutionize our culture and industry to treat aging seriously, and much more.
Reprogramming the cell from aged to healthy with siRNA - Dr. Janine & Rob (Junevity)
2025/12/09
Dr. Janine Sengstack and Rob Cahill, founders of the startup Junevity, are on a mission to extend lifespan and healthspan by combining AI and large scale omics data with genetic medicines known as “siRNAs”. Their cellular reset platform promises to create medicines that can reset each of your organs back to a healthy and youthful state.This year, Junevity successfully restored "18-year-old metabolism" in animal models allowing mice on a high-fat diet to lose fat while retaining muscle. This candidate therapy may become the first known drug to rejuvenate metabolism. Since our recording, Junevity doubled their seed round funding up to $20M to advance this work into human clinical trials, which means we might see their first rejuvenating medicine in the clinic as soon as the second half of next year.
Thiel fellow on how longevity can fix biotech - Lada Nuzhna
2025/12/02
