Minimum velocity for impact ejecta to form secondaries on terrestrial bodies
Communications Earth & EnvironmentThe minimum velocity (v) for impact ejecta to form secondary craters (secondaries) remains enigmatic, but it is a crucial parameter in untangling the fate of impact ejecta on planetary surfaces.

Ring‐Mold Craters on Ceres: Evidence for Shallow Subsurface Water Ice Sources
Geophysical Research Letters, 2018 One of the main tasks of the Dawn mission is to characterize the potentially ice‐rich crust of the dwarf planet Ceres. Ongoing studies reveal morphological features related to ice‐rich material such as pits or particular landslides.

Functional variation in butterfly egg pore traits: The potential role of climate
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

Transformer-Based Multi-Modal Fusion for Martian Impact Crater Classification
Remote SensingImpact craters, as key geomorphic features on Mars, provide important insights into surface processes and geological evolution. However, automatic classification of crater morphologies remains challenging due to substantial variations in size ...

Breadwinner backlash: The gendered effects of industrial decline
American Journal of Political Science, EarlyView.Abstract Low‐skilled men have long been vulnerable to globalization, decarbonization, and other forms of economic disruption. When shocks are realized, women often increase their paid labor to compensate for men's loss of income. We study how layoffs of low‐skilled men and concurrent shifts in workforce composition toward women affect voting.

Boreas, EarlyView.The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer
Boreas, EarlyView.Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Topographic Relaxation of Complex Impact Craters in a Clathrate Crust on Titan
The Planetary Science JournalTitan’s impact craters are significantly shallower than fresh craters on Ganymede, which are often used as templates for fresh craters on Titan. The presence of a clathrate crust on Titan, which would insulate the ice shell and maintain warmer ice near ...

Terrain Synthesis and Authoring based on Iso‐Contours
Computer Graphics Forum, EarlyView.Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.
