Macroalgal habitat shapes physiological responses of associated invertebrates to legacy and emerging contaminants

Pollution from legacy and emerging contaminants is a major threat to coastal ecosystems. Yet, the influence of habitat-forming species on the physiological responses of associated fauna to these stressors remains poorly understood. Macroalgal forests create complex environmental conditions that may alter contaminant sensitivity, but this possibility has received little experimental attention. To address this gap, the present study investigated the role of macroalgal forests, usingGongolaria b...

Feasibility and Safety of Strategic Multielectrode Positioning Guided by S3 Protocol for Hemodynamically Unstable Ventricular Tachycardia: The S3-STaMP Project

Background: Catheter ablation of scar-related ventricular tachycardia (VT) is often limited by hemodynamic instability. Strategic Multielectrode Positioning (STaMP) mapping has been proposed to enable rapid identification of the diastolic components of VT circuits in these patients. Objectives: This study sought to evaluate the feasibility and safety of STaMP mapping during nontolerated VT and the role of functional mapping with the S3 protocol. Methods: We analyzed 30 consecutive patients (m...

Perspective: can interfacial defects enhance graphene’s reactivity for gas–surface reactions under ultra-high vacuum?

A very recent experimental study [Proc. Natl. Acad. Sci. U.S.A. 123 (10) e2524790123] demonstrated that non-functionalized graphene (Gr) supported on silicon(111) catalyzed the decomposition of small sulfur-containing compounds under ultra-high vacuum. Accompanying density functional theory (DFT) calculations identify grain boundary defects (GBDs) and interfacial defects as the active sites. Functional carbon catalysts still encounter skepticism within the catalysis and surface science commun...
