Age‑and Sex‑Specific Genes Shape Lifespan Trade‑offs

Delighted to have contributed to this new study @Nature on the genetics of ageing and mortality 🧬 Using a large mouse cohort, we uncover age- and sex-specific genetic effects, including trade-offs where variants are beneficial early in life but detrimental later.

Longevity Linked to Ion Transport, Not Cell Division Genes

Why some species age slower than others remains a mystery. This is an impressive analysis of genes linked to longevity evolution in mammals. Genes associated with cell division & DNA repair show negative correlations with lifespan evolution, while positively correlated genes are...

Century of Gains Slows; Future Life Expectancy Uncertain

Life expectancy in high-income countries increased ~50% over the past century, but gains have slowed in recent decades (≈70 in 1975 to ≈80 today in US). What will be the life expectancy in 100 years?

Late‑stage Oral Cocktail Adds 33% Lifespan in Obese Mice

An oral drug combination, including a senolytic (quercetin), NR, urolithin A, and alpha-lipoic acid, extended median remaining lifespan in mice by 33%. Important to note, however, that the mice were fed a high-fat "Western Diet" and the intervention started at 18...

Electromagnetic Gene Switch Extends Lifespan in Progeroid Mice

Wow, a technique that allows electromagnetic control of gene expression in vivo 🤯 And they tested their system with OSK partial reprogramming, showing it extends lifespan in progeroid mice. In normal mice, they report health improvements and a small reduction in mortality...

Drugs May Slow, but Not Fully Reverse Aging

Just like we can't turn a human into a naked mole rat with drugs (requires too many specific molecular changes), I don't think we will fully reverse ageing pharmacologically. We may be able to slow human ageing with drugs, but reversing...

Disabling Light Sensing Extends Worm Lifespan by 40%

Great study in the bristleworm showing that light perception can regulate lifespan. Disrupting light sensing slows development, prolongs growth and extends lifespan by ~40%. More evidence that aging is not just damage accumulation, but is modulated by developmental processes.

Weight‑loss Drugs Boost Life by Aiding Sick, Not Slowing Aging

Weight loss drugs may increase human longevity but that's because they reduce the mortality of folks at the lower end of the lifespan distribution (i.e., unhealthy individuals), not because they delay the aging process. That's still valuable, but if this is...

AI Model Maps Cell Trajectories Driving Human Aging

Impressive temporal AI model of aging by @GladstoneInst Based on ~175M single-cell transcriptomes, the model predicts drivers of cell trajectories across human aging. Also great that the first author, Javier, trained in our lab. Always rewarding to see our alumni flourish.

Slowing Aging: A Targetable Process for Massive Health Gains

Aging may or may not be classified as a disease, but that’s largely semantics. What matters is that aging is a malleable, targetable biological process, and slowing human aging would result in massive health benefits.
