The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups
American Journal of Community Psychology, EarlyView.Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Journal of Applied Polymer Science, EarlyView.Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

The impact of trauma‐informed teacher education
British Educational Research Journal, EarlyView.Abstract In this study, two cohorts of university students in an employment‐based teacher education course undertook trauma‐informed education training embedded within their coursework to enhance their preparedness to work with diverse learners and their self‐efficacy for trauma‐informed teaching. With increased calls for teacher preparation programmes

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
