Metabolically, children are different species compared to adults

A great study, which once again puts metabolism in the spotlight. Many studies have tried to discover the main biological differences between children and adults and so far none of them have discovered a “smoking gun”. At the same time, multiple studies have demonstrated that children are much more resilient to both infections and “adult” … Read more

Inflammation (from PUFA), not telomeres, determines lifespan / healthspan

The idea of lifespan being entirely determined by limits on cellular division has ruled biology for more than a century and is perhaps best exemplified by the (in)famous (and false) Hayflick limit. Reaching the said limit is postulated to be controlled by telomere length, and as such the simplistic hypothesis materialized that could extend/control lifespan … Read more

Sexual activity and stress levels (HPA activity) may determine longevity

The study below tried to tease out the main factors affecting the longevity of the legendary naked mole rat – the animal with longest lifespan in its genus, and the sole mammal known to be virtually immune to developing cancer. Most of the biological/biochemical findings in regards to naked mole rats have already been found … Read more
