Advanced Intelligent Discovery, EarlyView.AI‐based tools enable rapid characterization of bacterial ultrastructure in low‐dose cryogenic transmission electron microscopy. The envelope thickness tool quantifies membrane thickness and anisotropy. The flagella module analyzes filament morphology and detects cell‐flagella contacts.

Latitude impacts continental acidity, biotic crisis and recovery.
Abstract Volcanism from large igneous provinces leads to increases in the Earth’s surface temperature and acidity, thus triggering mass extinction events. However, the dependence of acidity on latitudinal position has remained underexplored and is key to better understand, and react to, global environmental changes today.

American Journal of Agricultural Economics, EarlyView.Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Dynamic anoxic ferruginous conditions during the end-Permian mass extinction and recovery
Nature Communications, 2016 Oceanic anoxia is invoked for driving the Permo-Triassic Mass Extinction, but the timing, distribution and chemical state are poorly understood. Here, the authors show that fluctuations of anoxic, non-sulfidic (ferruginous) conditions were important for ...

Working with Latino Students in Recovery: Understanding Culture and the Role of Family [PDF]
, 2018 This presentation explores and reflects upon the presenter’s experiences after moving and adjusting to a new culture at a large university in deep-south Texas, on the US/Mexico border, and how those experiences align with current research available ...

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
