Rapid Impact Crater Relaxation Caused by an Insulating Methane Clathrate Crust on Titan

The Planetary Science Journal
Titan’s impact craters are hundreds of meters shallower than expected, compared to similar-sized craters on Ganymede. Only 90 crater candidates have been identified, the majority of which have low certainty of an impact origin.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Reducing the Compositional and Structural Degeneracy of Planetary Interiors

The interior conditions of planets are highly uncertain, because two types of intrinsic degeneracies – compositional degeneracy and structural degeneracy – prevent precise characterization.

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

Archaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Listening to young children with disabilities: Experiences of quality in mainstream primary education

British Educational Research Journal, EarlyView.
Abstract All children should have access to quality education through a child‐centred pedagogy. An inclusive, child‐centred pedagogy uses a strength‐based view of children that recognises each child as unique and competent, providing children with multiple opportunities to explore and learn at their own pace.

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Employing Magnetic Field Records at Key Moments in Planetary Evolution

The analysis of the paleomagnetic record in meteorites provides a unique and powerful viewpoint on early solar system and planetary evolution. Indeed, meteorites are the only tangible objects that bore witness to these important events, making their ...
