Towards Allyship in Diversity? Critical Perspectives on the European Union's Global Role

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract This special issue (SI) foregrounds critical perspectives in studying the EU's global role, acknowledging their historical marginalisation within scholarship dominated by mainstream approaches. The project is theoretical with significant normative and practical implications, that is, for activism and policy‐making. Our primary goal is to bring

The Australian Plant Breeder's Rights Act 1994 (Cth) and how it is used for Australian native plants

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract With increasing interest in intellectual property relating to plants, it is timely to assess the use of Plant Breeder's Rights (PBRs) in Australia for native plants, with tens of thousands of native plants nearly all of which are endemic and many with known uses.

‘No es la democracia que míster superman quiere imponernos desde Washington’: An analysis of populist attitudes on democracy from Latin American legislators

open access: yesLegislative Studies Quarterly, EarlyView.
Abstract In studies on Populism, extensive discussion has mounted around whether the phenomenon represents a threat to democracy or a corrective force. In line with this concern, we examine whether the populist attitudes held by legislators are related to their opinions on the functioning of and satisfaction with three central aspects of governance: (I)

Insights on the volcanic and impact histories of the lunar nearside from the petrology, geochemistry, and geochronology of the Calcalong Creek lunar regolith breccia meteorite

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 392-421, March 2025.
Abstract The Calcalong Creek lunar meteorite is a regolith breccia with a lithologically diverse array of clasts set in a glassy, highly vesicular matrix. Here, we present a comprehensive new analysis of the meteorite. Comparisons to remote sensing data, lunar sample lithologies, and lunar sample ages indicate that it was likely sourced from regolith ...

Using X‐ray computed microtomography (μCT) to determine subsample‐specific cosmogenic noble gas production rates of E (enstatite) chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 442-463, March 2025.
Abstract Cosmic ray exposure (CRE) ages provide information about the parent bodies and source regions of meteorite classes. Cosmogenic noble gases are often used to quantify exposure time scales ranging from tens of ka to hundreds of Ma. The production rate of cosmogenic noble gases is primarily controlled by a meteorite's chemical composition ...

A primitive asteroid that lived fast and died young sampled by a xenolith in the Cold Bokkeveld CM2 carbonaceous chondrite

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.
Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

Iron and copper sulfides in asteroid (162173) Ryugu: Formation conditions and a comparison to the CI and CY chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 506-528, March 2025.
Abstract JAXA's Hayabusa2 sample return mission visited the volatile‐rich carbonaceous (C‐type) asteroid (162173) Ryugu with the aim of ground‐truthing remote observations, returning a pristine sample from a C‐type asteroid, and strengthening links between asteroids and the meteorite collection. Here, we have conducted a systematic study of coarse (>10

The solar system Fe/Mg ratio

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 529-543, March 2025.
Abstract Solar wind Fe and Mg fluences (atoms/cm2) were measured from Genesis collectors. Fe and Mg have similar first ionization potentials and solar wind Fe/Mg should equal the solar ratio. Solar wind Fe/Mg is a more valid measure of solar composition than CI chondrites and can be measured more accurately than spectroscopic photospheric abundances ...
