Group B streptococci lyse endothelial cells to infect the brain in a zebrafish meningitis model

This study shows that Group B Streptococcus (GBS) causes meningitis by lysing endothelial cells in zebrafish, not through transcytosis, and identifies inflammation and clotting as key factors in brain invasion.

Transient Vascular Occlusions in a Zebrafish Model of Tuberculous Meningitis

This study uses a zebrafish model to show mycobacteria cause transient vascular occlusions and ischemia during early brain infection, establishing a model for TBM vascular complications.

Developmentally-regulated proteolysis by MdfA and ClpCP mediates metabolic differentiation during Bacillus subtilis sporulation

The paper shows that MdfA and ClpCP protease regulate metabolic differentiation in Bacillus subtilis sporulation by depleting metabolic enzymes in the forespore.

Empowering STEM Students: A University-wide Mentorship Program Fostering Retention and Belonging

The paper describes a mentorship program aimed at retaining STEM students from historically excluded groups by providing mentorship, research opportunities, and professional development.

Functional reconstitution of a bacterial CO2 concentrating mechanism in E. coli

The paper demonstrates that a bacterial CO2 concentrating mechanism enables E. coli to fix CO2 from ambient air using 20 CCM genes.
