Methane Activation by B5+ Toward a CB5H2+ Isomer Containing a Planar Tetracoordinate Carbon Atom

open access: yesAngewandte Chemie International Edition, EarlyView.
Methane activation by B5+ yields CB5H2+ through H2 elimination. Electronic‐structure calculations connect the nascent dehydrogenation product to a low‐lying isomer containing a planar tetracoordinate carbon atom. ABSTRACT Planar tetracoordinate carbon (ptC) motifs have been identified predominantly in the global‐minimum structures of gas‐phase clusters

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Contrasting Heatwave Regimes in Dry and Humid Subtropical Mexico: A Station‐Based Probabilistic Assessment

open access: yesInternational Journal of Climatology, EarlyView.
Heatwaves have intensified under a warming climate, producing substantial environmental and societal impacts. This study characterizes heatwave regimes in two contrasting regions of Mexico using a percentile‐based threshold and a Poisson distribution framework.

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

From wild to tamed: Reimagining novel crops through omics and local plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

open access: yesJournal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...

Opportunities and Alliances: The Relational Dynamics of Criminal Collusion in Latin America

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Based on ethnographic fieldwork in Mexico and judicial wiretap analysis in Argentina, this paper shows that collusion between state actors and violent non‐state actors operates through fluid and competitive relational networks rather than stable hierarchies or fixed institutional arrangements.

Impact of Prior Biologic Mechanism of Action on Anti‐TNF Effectiveness in Inflammatory Bowel Disease: An ENEIDA Registry Study

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
In this nationwide ENEIDA registry study, anti‐TNF therapy after prior exposure to a different biologic mechanism of action showed reduced treatment durability in inflammatory bowel disease, with a particularly marked impact in ulcerative colitis, where short‐ and long‐term clinical effectiveness was also lower. ABSTRACT Background The expanding use of
