Science communication tools: rubrics for generating posters and manuscripts that are authentic to the practice of science

Tamarah L. Adair, Swati Agrawal, Yesmi Ahumada-Santos, Regina V. Alvarez et autres

Traditional undergraduate science courses often prioritize content mastery over authentic engagement with the scientific process. Course-based research, also referred to as course-based undergraduate research experiences (CUREs), addresses this limitation by immersing students in authentic scientific practice. In course-based research, assessment practices can …

Comparative genomic analysis of Cluster AZ Arthrobacter phages

Amanda C. Freise, Kieran P. Furlong, Karen K. Klyczek, Andrea R. Beyer et autres

Abstract Bacteria in the Arthrobacter genus belong to the phylum Actinobacteria and are primarily soil-dwelling. Over 600 bacteriophages infecting Arthrobacter hosts have been isolated and sequenced, and genomic analyses show these phages to be highly diverse with mosaic genome architectures. We describe …

The professional identity of STEM faculty as instructors of course-based research experiences

David I. Hanauer, Richard M. Alvey, Ping An, Christa T. Bancroft et autres

The professional identity of scientists has historically been cultivated to value research over teaching, which can undermine initiatives that aim to reform science education. Course-Based Research Experiences (CRE) and the inclusive Research and Education Communities (iREC) are two successful and impactful reform …

Genome and characteristics of Arthrobacter globiformis AZ cluster phage London

Andrea R. Beyer, Hannah L. Hatke Hughes, J.Y. Bullock, Demesha T. Daniels et autres

ABSTRACT London is a predicted temperate bacteriophage with siphovirus morphology infecting Arthrobacter globiformis NRRL strain B-2880. Sequencing of the genome revealed a length of 43,599 bp comprising 69 predicted open-reading frames and no tRNA genes. It is categorized as a cluster AZ1 …

„Sich seiner selbst bewusstes Denken“. Plädoyer für einen Perspektivwechsel

Andrea R. Beyer

Der Beitrag befasst sich kritisch mit dem Konzept des „hebräischen Denkens“, für das die Aspektive kennzeichnend und ein Ausweis dessen phylogenetischer Jugend sei. Anhand grundsätzlicher Überlegungen und eines Gedankenspiels zu einem kasuistischen Text wird deutlich, dass Sprache Denken nicht identisch abbildet, sondern …

Functional Characterization of Non-Ankyrin Repeat Domains of Orientia tsutsugamushi Ank Effectors Reveals Their Importance for Molecular Pathogenesis

Sarika Gupta, Jason R. Hunt, Haley E. Adcox, Shelby E. Andersen et autres

Orientia tsutsugamushi is a genetically intractable obligate intracellular bacterium, causes scrub typhus, and has one of the largest known armamentariums of ankyrin repeat-containing effectors (Anks). Most have a C-terminal F-box presumed to interact with the SCF ubiquitin ligase complex primarily based on …
