A Critical Appraisal of Labour's AI Agenda

open access: yesThe Political Quarterly, Volume 97, Issue 1, Page 125-132, January/March 2026.
Abstract This article critically evaluates Labour's ambitious AI agenda, situating it within the historical trajectory of UK AI policy and the techno‐solutionist assumptions underpinning current strategies. While Labour frames AI as a transformative tool for economic growth, state efficiency and public service reform, we argue that structural ...

Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...

Biological and Biologically Inspired Functional Nanostructures: Insights into Structural, Optical, Thermal, and Sensing Applications

open access: yesAdvanced Materials, Volume 37, Issue 51, December 23, 2025.
Biological and biologically‐inspired functional nanostructures with structural, thermal, optical, and sensing applications are reviewed. The role of nanoscale features in biological materials on performance is described, and their blueprints are used for bio‐inspired nanomaterials, synthesized using advanced techniques (i.e., photolithography, bio ...

Constrained variation in the internal architecture of avian wing bones

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3611-3627, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Extant birds exhibit remarkable ecological disparity accompanied by widespread skeletal convergence driven by functional adaptation. Investigations of morphofunctional associations with ecological factors have frequently focused on the external morphology of avian wing ...

From “Modern Midas Mineral” to “Satanic Substance”: Uranium, Unions, and the Atomic Age

open access: yesAustralian Journal of Politics &History, Volume 71, Issue 4, Page 735-752, December 2025.
Uranium mining and export was a major flashpoint for political debate in 1970's Australia. However, there has been relatively little investigation into how uranium was understood and contested before this time. This paper draws on labour movement publications and other archival sources to reveal lesser‐known antecedents to the anti‐uranium movement in ...
