#578 Engineering Longevity: Dr. Bill Andrews on Telomeres, Genetics, and the Future of Aging

What if aging is not inevitable, but a solvable biological problem?

In this episode of The CTO Show with Mehmet, Mehmet sits down with Dr. Bill Andrews, a renowned molecular geneticist and pioneer in telomere research. Dr. Andrews has spent decades studying the mechanisms of aging and is known for leading discoveries around telomerase, the enzyme connected to cellular aging.

The conversation explores the biological root causes of aging, the role of telomeres in limiting human lifespan, and the scientific pursuit of extending human healthspan. Dr. Andrews also shares insights into the challenges of biotech innovation, the economics of pharmaceutical research, and why breakthroughs in longevity science often struggle to reach the public.

This episode bridges biology, technology, and the future of human health, offering a deep dive into one of the most fascinating scientific frontiers of our time.

Key Takeaways

• Aging may be driven by the shortening of telomeres, protective caps at the ends of chromosomes.

• The Hayflick Limit suggests human cells can only divide a finite number of times.

• Telomerase is an enzyme that can extend telomeres, potentially slowing or reversing aspects of aging.

• Longevity research faces major challenges due to funding structures and biotech investment models.

• Many scientists believe extending healthspan, not just lifespan, should be the primary goal of longevity science.

• Advances in biotechnology could eventually transform aging from an inevitability into a treatable biological process.
