Peter Fedichev’s Physics-Based Approach to Aging: A New Longevity Framework

Peter Fedichev describes aging as a three-variable system of stress (from physical, psychological, or molecular stressors), noise (small random biological fluctuations), and damage (cumulative wear-and-tear).

Peter Fedichev has proposed a physics-based framework for aging, encompassing stress, noise (small random biological fluctuations), and damage (cumulative wear-and-tear).

What Is Mosaic Aging? How Organs Age at Different Rates

A new framework proposes that the patchwork nature of aging, where different organs deteriorate at different speeds, may hold the key to understanding the ultimate cause of death.

A new framework proposes that aging occurs unevenly in cells, tissues, and organs, and that targeting the fastest-aging tissues may extend lifespan.

Aging Guru Bryan Johnson’s Supplement List for 2026

Changes to Bryan Johnson’s latest supplement stack include taking NMN or NR six days a week, rather than seven, and eliminating the use of rapamycin.

Changes to Bryan Johnson’s updated 2026 supplement stack include taking NMN or NR six days a week instead of seven and removing rapamycin.

Model: 14- to 15-month-old male C57BL/6J mice
Dosage: 50 mg injection of 3′-deoxyadenosine (cordycepin) because it was shown not to be absorbed if administered orally

Mushroom Compound Prolongs Lifespan If Taken At Correct Time

In mice, cordycepin—a molecule found in cordyceps mushrooms—prolongs lifespan and improves memory, strength, cardiac function, hormone levels, and metabolism.

Model: 11-month-old male C57BL/6J mice 
Dosage: 30 mg/kg/day of NTX-748 (based on a small molecule called 78c) for 4 months, administered orally

Blocking NAD+ Breakdown Improves Cognitive and Physical Performance

Buck Institute scientists find that blocking the CD38 enzyme, which elevates NAD+ (nicotinamide adenine dinucleotide), counteracts age-related cognitive and physical decline in mice.
