Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The Heterogeneity of Socially Isolated Older Adults: A Social Isolation Typology
Recent statistics show a growing number of older adults who are living alone and are socially isolated. It is against this background that, in recent years, many interventions have been developed to address social isolation among the elderly. Evaluative studies show that most interventions are hardly effective, though.

Combating Social Isolation among Older Immigrant Adults: A Qualitative Interpretive Meta-Synthesis
Older immigrants totaled 7.3 million in 2018, representing 13.9 percent of the population of seniors in the U.S. While this population is found to contribute significantly to society, along with new opportunities comes circumstantial challenges. Of these,

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Social isolation induces hyperactivity and exploration in aged female mice.
Prolonged social isolation is associated with poor physical and mental health outcomes, findings observed in both humans, and rodent models of isolation.

Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Modulation of social valence by insular cortex activity during acute social isolation in mice
For social animals, social isolation is a potential threat to survival, and therefore can be considered innately aversive. Long-term social isolation induces a variety of social and affective deficits and has been used as a stress model in animal studies,
