Why do animals age in such similar ways, yet live for wildly different spans - from days to a century? Our new paper in @NatureAging fits a damage accumulation model across 9 species and finds the knob that best predicts lifespan doi.org/10.1038/s435...

A damage accumulation model identifies distinct aging regimes across species - Nature Aging

Raz and colleagues fit survival data across species to a stochastic model of damage accumulation and removal. They report that damage production rate best predicts lifespan and reveal two distinct agi...

What happens just before we die? Are the last stages of deterioration driven by different dynamics, or the same processes driving aging all our lives? Turns out it's the latter, as we show in our new preprint! 🔬 doi.org/10.64898/202... 🧵 1/5 #AgingResearch #SystemsBiology

Identify. Attack. Resolve. The immune system follows a perfect defense program: ignore weak/self signals, attack true threats with force, then shut down to avoid damage. (1/2) www.science.org/doi/10.1126/...

Excitability as a design principle in the immune system

A simple pulse-and-rest circuit may explain how immune cells strike hard at threats yet avoid self-destruction.

We analyzed changes in physiology relative to menopause using two large scale studies that include millions of lab tests. Rather than align by age, we used statistical inference to align tests to final menstrual period. (1/2) arunamed.com/the-menopaus...

The Menopause Cliff: What a Million Women's Lab Tests Reveal

TLDR: A massive study of 300+ million lab tests from 1+ million women just proved what women have been saying for years: menopause isn't a gradual slope—it's a physiological cliff. Nearly e

Compression of morbidity by interventions that steepen the survival curve - Nature Communications

Longevity research aims to extend lifespan and reduce sickspan in aging. Here, the authors show that only interventions that steepen survival curves can compress the sickspan relative to lifespan.

Why do cortisol-lowering drugs work for Cushing’s but fail in mood disorders & chronic stress? We propose that the ability of the pituitary and adrenal glands to adjust their functional masses—normally beneficial—counteracts the drug’s effect. Using a math. model, we screened HPA interventions (1/2)
