Backgound Information: RNA plays crucial roles in cellular organization and metabolism, and modulating its activity is essential for maintaining cellular functions. RNA activity, involving both catalytic (ribozymes) and translation processes, is controlled via myriad mechanisms involving different binding partners such as proteins and smaller polar solutes. We previously reported that lipid membranes can directly interact with the artificial R3C ribozyme changing its activity, however, the effect of lipids on naturally occurring ribozymes remains unknown.

Objectives: A growing body of research has identified associations between family size and cognition in older adults. These studies largely focus on older adults' own fertility history instead of sibship size, defined as one's number of siblings. Sibship size may impact cognitive development during early childhood, creating differences that may persist into late-life.

The continuous interaction between phages and their respective hosts has resulted in the evolution of multiple bacterial immune mechanisms. However, the diversity and prevalence of antiviral defense systems in complex communities are still unknown. We therefore investigated the diversity and abundance of viral defense systems in 3,038 high-quality bacterial and archaeal genomes from the rumen.

Article Synopsis
  • * Using data from the Mexican Health and Aging Study, the research analyzes how actors' (individuals') and partners' (spouses') perceptions of marital power relate to cognitive performance over time, with an emphasis on depression as a mediating factor.
  • * Results indicate that lower marital power is associated with decreased cognition, especially for husbands, while women's marital power imbalances lead to higher depression rates for both partners, suggesting a significant link between marital dynamics and cognitive health in older adults.
