Sex-specific effects of parental age on the physiology of offspring in a long-lived seabird

Studying senescence in wild organisms reveals evolutionary trade-offs and life-history strategies that cannot be captured in laboratory settings. Long-lived seabirds from rare known-aged populations provide excellent models for examining aging under natural conditions. Because re...

Getting Around the Intrinsic Errors of Density Functional Theory Calculations in Electrocatalysis

Abstract This article shows that the intrinsic gas-phase error in density functional theory (DFT) calculations can be effectively eliminated by referencing adsorption energies and reaction barriers to surface-bound intermediates rather than to molecular species. In oxygen reducti...

Comprehensive NMR metabolomic profiling reveals a pro-atherogenic signature in psoriasis

Abstract Psoriasis (PS) is a chronic inflammatory skin disease associated with cardiometabolic comorbidity. While systemic inflammation is recognized as a major driver of this risk, metabolomic signatures linking PS to cardiometabolic dysfunction remain incompletely defined. The...

Conversational AI should fill the white space in mental health care, not replace humans

Abstract Conversational AI (CAI) is being rapidly deployed in mental healthcare, with much of the focus on chatbots delivering therapy directly to patients. However, this focus overlooks broader opportunities to improve mental healthcare as a system. Rather than replacing clinici...

Thermal activation and pozzolanic reactivity assessments of Estonian clays for cementitious applications

Abstract This study evaluates the pozzolanic reactivity of locally sourced Estonian clays as supplementary cementitious material (SCM) alternatives. Two selected clays, Arumetsa (ARC) and Aseri (ASC), were calcined in a rotary tube furnace at three distinct temperatures (750 °C,...
