A well‐resolved phylogeny of Cuscuta subgenus Monogynella based on data drawn from all three plant genomes

American Journal of Botany, EarlyView.
Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Iron Age and Anglo-Saxon genomes from East England reveal British migration history

Nature Communications, 2016
This study examines ancient genomes of individuals from the late Iron Age to the middle Anglo-Saxon period in the East of England. Using a newly devised analytic algorithm, the author also estimate the relative ancestry of East English genome derived ...

The absence of women's scientific contributions in core UK pre‐university science qualifications

British Educational Research Journal, EarlyView.
Abstract Despite their groundbreaking contributions to our understanding of the natural world and the universe, women's roles in biology, chemistry, physics, astronomy, environmental science and geology remain largely absent from standard educational specifications in the United Kingdom (UK), particularly at Key Stage 4 (KS4) and Key Stage 5 (KS5), or ...

Scaffolding a Low‐Cost Experiential Bioreactor Module: Reducing Cognitive Load to Enhance Competency and Self‐Efficacy

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Low‐cost experiential modules are critical for democratizing biotechnology education, yet most undergraduates lack hands‐on experience with continuous‐culture bioreactor operations, which are fundamental to industrial bioprocessing. This study employed design‐based research across two iterative cycles (Fall 2024, n = 8; Fall 2025, n = 11) to ...

Ground squirrel coprolites preserve complex archives of ancient environmental DNA over 700,000 years

Nature Communications
Permafrost-preserved ground squirrel (Urocitellus) burrows in Yukon, Canada contain coprolites (palaeofaeces) that span from the Holocene to at least the Middle Pleistocene (~700 kya). Using shotgun metagenomics and targeted enrichment, we recover a rich,

Ant Diversity of the Xisha Islands: Community Structure, Exotic Species Colonization, and Ecological Functions in a Tropical Coral Archipelago

Biological Diversity, EarlyView.
The first inventory of ants from the Xisha Islands of the South China Sea was compiled, revealing 21 species: 70% native and 30% exotic. Anthropogenic disturbance primarily drove exotic colonization, whereas island area showed weak positive effects on species richness. Most ants were omnivorous, with key mutualistic and seed‐dispersal roles.
