Aeciospore ejection in the rust pathogen Puccinia graminis is driven by moisture ingress.

Fungi have evolved an array of spore discharge and dispersal processes. Here, we developed a theoretical model that explains the ejection mechanics of aeciospore liberation in the stem rust pathogen Puccinia graminis. Aeciospores are released from cluster cups formed on its Berberis host, spreading early-season inoculum into neighboring small-grain crops.

Firearms storage safety discussions in VA primary care: Staff perspectives.

Objective: To describe VHA primary care clinician and staff perspectives on conducting firearms storage safety (FSS) discussions in primary care, and to identify key approaches for primary care teams to facilitate FSS conversations.

Method: Qualitative analysis of transcripts and notes from focus groups with VA primary care staff and individual semi-structured interviews with primary care clinicians. One hundred-seven VHA primary care team members participated in one of four focus groups or individual semi-structured interviews (n = 5).

Nondestructive, high-resolution, chemically specific 3D nanostructure characterization using phase-sensitive EUV imaging reflectometry.

Next-generation nano- and quantum devices have increasingly complex 3D structure. As the dimensions of these devices shrink to the nanoscale, their performance is often governed by interface quality or precise chemical or dopant composition. Here, we present the first phase-sensitive extreme ultraviolet imaging reflectometer.
