DNA methylation correlates with lifespan and predicts remaining lifespan in the zebra finch
Biomarkers that correlate with age are essential tools for understanding aging and lifespan variation. DNA methylation (DNAm) changes predictably with age in parts of the genome. In humans, epigenetic...

Kudos to @science.org for this self-analysis of the peer review process. These kind of data are never shared and don't have to be. Wildly refreshing to see it out in the open. Editorial and peer review dynamics at elite general science journals | Science Advances www.science.org/doi/10.1126/...

Using the epigenome as a telescope? 🧬 🔭 In our new paper, we show that the epigenome can work like a telescope: just as telescopes capture light from stars that no longer exist, DNA methylation patterns in adulthood carry the “light” of early-life environments that are long gone.

Utilizing longitudinal telomere data from captive zebra finches, we have shown that birds with shorter lifespans show faster telomere shortening, particularly among the longer telomeres in the genome. 🐦🧬⌛ academic.oup.com/jeb/advance-...

"Asynchrony of ageing among traits in a wild bird population" doi.org/10.32942/X27...
The age-specific trajectories of 13 phenotypic traits in individuals the Seychelles warbler population of Cousin Island (dates differ per dataset, minimum date 1981, maximum date 2022) identified through Generalized Additive Models. The x-axis is age in years, and the y-axis is the trait value; all traits, except for annual reproductive success, survival and malaria, are z-transformed. The solid black line depicts the model-predicted curve and the grey shaded areas depict the standard error. Blue points are raw data points. RTL = relative telomere length. ARS = Annual Reproductive Success. For buffy coat (Fig 1h & i), F indicates female, M indicates male.

Will a child survive? Older siblings have a powerful influence
Swiss birth data from 1750 to 1870 reveal that girls who had lots of older brothers close to their own age were less likely to survive than were those who did not.
