longevity of most persons did not collide with the life-span boundary of the human species. It is improbable that a laboratory mouse that on averagelives 2 years will survive for 4 years, no matter how much we engineer its environment. Jeanne Calment lived to the age of 122 years (Coles,...
Discerning the relationship between sociality and longevity would permit a deeper understanding of how animal life history evolved. Here, we perform a phylogenetic comparative analysis of ~1000 mammalian species on three states of social organization (so

Meanwhile, in 2023, Guinness World Records recognized Pat the mouse as the oldest mouse alive at a little over nine and a half years old—just a sliver in years compared to humans. When it comes to lifespan, we mammals have an astonishing range. The common shrew lives less than two year...
To fill this knowledge gap, we defined age-associated DNA methylation changes at the whole-genome, single-nucleotide level in mouse liver and tested the impact of longevity-promoting interventions, specifically the Ames dwarf Prop1 df/df mutation, calorie restriction and rapamycin. Results In wild-...
Conversely, overexpression of pry-1 in muscles improved both phenotypes. Thus, pry-1 appears to affect life span by regulating muscle mitochondria health. Interestingly, muscle-specific expression of mouse Axin (mAxin1) in C. elegans also extended life span, suggesting that Axin's role in ...
Nephrogenesis cessation timing in mice is determined by a community effect and is tunable by altering the perception of WNT signalling strength by nephron progenitor cells to favour self-renewal versus differentiation. The twofold range in nephron number observed between mouse strains could be leveraged...
” said Matthew Zipple, a Klarman Postdoctoral Fellow in neurobiology and behavior at Cornell University. “What we’re putting forward is that a part of the explanation for our long lifespan is this other foundational aspect of our lives, which is the relationship between the mother and her ...
