Phylogenetic and taxonomic revisions of Jurassic sea stars support a delayed evolutionary origin of the Asteriidae.

Background: The superorder Forcipulatacea is a major clade of sea stars with approximately 400 extant species across three orders (Forcipulatida, Brisingida, Zorocallida). Over the past century, the systematics of Forcipulatacea have undergone multiple revisions by various authors, with some considering numerous families such as Asteriidae, Zoroasteridae, Pedicellasteridae, Stichasteridae, Heliasteridae, Labidiasteridae, and Neomorphasteridae, while others recognized only two families (., Asteriidae and Zoroasteridae).

Transposon-sequencing (Tn-seq) of the Candida glabrata reference strain CBS138 reveals epigenetic plasticity, structural variation, and intrinsic mechanisms of resistance to micafungin.

Candida glabrata (also called Nakaseomyces glabratus) is an opportunistic pathogen that can resist common antifungals and rapidly acquire multidrug resistance. A large amount of genetic variation exists between isolates, which complicates generalizations. Portable transposon-sequencing (Tn-seq) methods can efficiently provide genome-wide information on strain differences and genetic mechanisms.

Understanding the Multiple Influences on Black Parents' School Involvement: A Longitudinal Perspective.

This study explores longitudinal influences of various factors on Black parents' involvement in their children's education. Guided by Hoover-Dempsey & Sandler's Model of Parent Involvement, this research examines whether parents' school climate perceptions, attitudes about involvement, self-efficacy, and children's academic performance predict parent involvement over time. Utilizing data from the Maryland Adolescence in Context Study with a sample of 560 Black parents, we found that positive school climate perceptions and favorable attitudes towards involvement significantly predict increased parent involvement in later years.
