Correlates of early reproduction and apparent fitness consequences in male Soay sheep

open access: yesEcology and Evolution, 2023
Life history trade‐offs are ubiquitous across species and place constraints on the timing of life history events, including the optimal age at first reproduction.

The Target Selects the Toxin: Specific Amino Acids in Snake-Prey Nicotinic Acetylcholine Receptors That Are Selectively Bound by King Cobra Venoms

open access: yesToxins, 2022
Snake venom is an adaptive ecological trait that has evolved primarily as a form of prey subjugation. Thus, the selection pressure for toxin diversification is exerted by the prey’s physiological targets, with this pressure being particularly acute for ...

Mating system variation drives rapid evolution of the female transcriptome in Drosophila pseudoobscura [PDF]

open access: yes, 2014
This research was part funded by the Natural Environment Research Council, Grant Number: NE/I014632/1. The APC was paid through RCUK open access block grant funds.Interactions between the sexes are believed to be a potent source of selection on sex ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Digital Lovers and Jealousy: Anticipated Emotional Responses to Emotionally and Physically Sophisticated Sexual Technologies

open access: yesHuman Behavior and Emerging Technologies
Technologies that stimulate human social and sexual impulses could affect users and societies. Here, we report on two experiments designed to test participant responses to (1) “virtual friend” chatbots that vary in capacity to engage users socially and ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Different effects of accelerated development and enhanced growth on oxidative stress and telomere shortening in amphibian larvae

open access: yesScientific Reports, 2017
Organisms react to environmental changes through plastic responses that often involve physiological alterations with the potential to modify life-history traits and fitness. Environmentally induced shifts in growth and development in species with complex

Entropy and Entropy Production: Old Misconceptions and New Breakthroughs

open access: yesEntropy, 2013
Persistent misconceptions existing for dozens of years and influencing progress in various fields of science are sometimes encountered in the scientific and especially, the popular-science literature.

Migration dynamics of an important rice pest: The brown planthopper (Nilaparvata lugens) across Asia—Insights from population genomics

open access: yesEvolutionary Applications, 2020
Introduction Brown planthoppers (Nilaparvata lugens) are the most serious insect pests of rice, one of the world's most important staple crops. They reproduce year‐round in the tropical parts of their distribution, but cannot overwinter in the temperate ...
