Could Aging Leave a "Memory" That Spreads and Even Passes to the Next Generation?

A new aging model posits that aging imprints signatures across molecular, tissue, and organ system levels, and these signatures may also transmit across generations.

A new theory posits that aging imprints molecular-, cellular-, tissue-, and organ system-level signatures that may transmit across generations.

Aging &amp; Longevity

Based on current scientific evidence, Dutch researchers have ranked existing anti-aging interventions based on how likely they are to protect against DNA damage and aging.

The Anti-Aging Debate Everyone’s Talking About: Inside Bryan Johnson’s Jubilee Showdown

Bryan Johnson debates 20 skeptics on anti-aging in Jubilee’s viral episode and challenges assumptions about lifespan, science, and the future of human health.


<p>Model: Young C57BL/6J mice fed a high protein (56% of daily calories) diet for 20 weeks </p>
<p>Dosage: Injection with either 400 mg/kg of NMN or 20 mg/kg of 78c for 4 weeks</p>


High protein intake improves the body composition of aged mice, but it lowers NAD+ (nicotinamide adenine dinucleotide) levels and promotes metabolic aging.

How to Boost Mitochondrial Tissue Density and Quality for Longevity

Lifestyle hacks contrived to promote the tissue density and quality of mitochondria (the cell’s powerhouses) can aid in the efficient generation of cellular energy and reduce inflammation, thereby promoting longevity.
