Macroorganisms are inhabited by microbial communities that often change through the lifespan of an individual. One of the factors contributing to this change is colonization from the environment.

On the emergence of the correlation between life expectancy and the variance in the age at death
Recent empirical studies have found various patterns in the correlations between lifespan inequality and life expectancy in modern human populations. However, it is unclear how general these regularities are. Here we establish three theorems that provide

Many environmental factors that dynamically change in nature influence various aspects of animal physiology. Animals are equipped with sensory neuronal systems that help them properly sense and respond to environmental factors. Several studies have shown

Neurodevelopmental origins of lifespan changes in brain and cognition [PDF]
Significance Brain and cognition change with age, with early gains and later declines. Attempts have been made to identify age-specific mechanisms, focusing on when and how declines begin in adults. However, even though general cognitive ability declines with age, there is a high stability in individuals’ cognitive ability relative to their ...

Lifespan Changes in Global and Selective Stopping and Performance Adjustments [PDF]
This study examined stopping and performance adjustments in four age groups (M ages: 8, 12, 21, and 76 years). All participants performed on three tasks, a standard two-choice task and the same task in which stop-signal trials were inserted requiring either the suppression of the response activated by the choice stimulus (global stop task) or the ...

A lifespan program of mouse synaptome architecture [PDF]
## This item has been replaced by the one which can be found at https://doi.org/10.7488/ds/2796 ## How synapses change molecularly during the lifespan and across all brain circuits is unknown.

Two aspects of longevity are associated with rates of loss of telomeres in birds
Telomeres, the terminal repetitive DNA sequences at the ends of linear chromosomes, have strong associations with longevity in some major taxa. Longevity has been linked to rate of decline in telomere length in birds and mammals, and absolute telomere ...

How have trends in lifespan variation changed since 1950? A comparative study of 17 Western European countries [PDF]
Lifespan variation adds to life expectancy by measuring the inequality surrounding age of death that a population faces. Countries that tackle premature mortality generally have decreasing lifespan variation but this is the first study to compare and ...

Change and Continuity in Attitudes Toward Homosexuality Across the Lifespan [PDF]
This study examines differential stability in attitudes towards homosexuality using panel data representative of the American adult population. While attitudes towards homosexuality have shifted considerably on the aggregate-level over the past few ...

A genomic lifespan program that reorganises the young adult brain is targeted in schizophrenia
The genetic mechanisms regulating the brain and behaviour across the lifespan are poorly understood. We found that lifespan transcriptome trajectories describe a calendar of gene regulatory events in the brain of humans and mice.
