University of Cincinnati emergency medicine physician Natalie Kreitzer, MD, received a $2.5 million National Institutes of Health R01 grant to lead a clinical trial testing a wellness program for family caregivers of traumatic brain injury patients.

A UMBC-led team has revealed how the common hospital pathogen Pseudomonas aeruginosa senses iron with a sophisticated two-protein switch that dramatically rewires its metabolism and biofilm defenses. Published in Nature Communications, the discovery led by chemist Aaron Smith and collaborators at Oklahome State University points to a promising new target for combating stubborn, antibiotic-resistant infections—and shows how student-driven research can bridge chemistry and biology to tackle real-world health threats.
