This twin study examined the genetic and environmental etiology of vocabulary, syntax, and their association in first graders. French-speaking same-sex twins (n = 555) completed two vocabulary tests, and two scores of syntax were calculated from their spontaneous speech at 7 years of age. Multivariate latent factor genetic analyses showed that…

Mutation, diversity, natural selection and the biology of human pathogens (including antibiotic resistance) are key features of the biosciences curriculum at A Level and undergraduate study. Few resources exist to allow students to engage with these topics in an interactive manner. This paper describes an interactive, online simulation of mutation…

Purpose: Keeping Spivak's essay "Can the Subaltern Speak?" in mind, the purpose of this paper is to examine the itinerant curriculum theory (ICT) as a subaltern momentum unveiling how ICT informs subaltern ways of being and thus, potentially, the research lens for qualitative approaches. In this context, the paper examines how curriculum…

We describe a game and teachers' experiences using it in their middle and high school science courses. The game, which is called "Luck of the Draw", was designed originally to engage medical students and later adopted for middle school, high school, and college students in genetics, and to encourage critical thinking about is-sues such…

The prelimbic cortex has been implicated in the consolidation of previously learned fear. Herein, we report that temporarily inactivating this medial prefrontal cortex subregion with the GABA [subscript A] agonist muscimol (4.0 nmol in 0.2 µL per hemisphere) was able to equally disrupt 1-, 7-, and 21-d-old contextual fear memories after their…

Objectives: Children and adolescents with chronic physical health conditions are also at elevated risk of poor mental health; the mechanisms to account for this relationship remain unclear. In this narrative review, we used the socio-ecological model to examine research on experiences of school for children with chronic health conditions and how…

The purpose of this study is to interpret and qualitatively characterise the content in some research articles and evaluate cases of possible difference in meanings of the gene concept used. Using a reformulation of Hirst's criteria of forms of knowledge, articles from five different sub-disciplines in biology (transmission genetic, molecular…

Recent years have seen a dramatic increase in our understanding of the social behaviour of microbes. Here, we take advantage of these developments to present an undergraduate laboratory exercise that uses the cooperative flocculating behaviour of yeast ("Saccharomyces sp.") to introduce the concept of inclusive fitness and teach the…

Rett Syndrome (RTT) is characterized by severe impairment in fine motor (FM) and expressive language (EL) function, making accurate evaluations of development difficult with standardized assessments. In this study, the administration and scoring of the Mullen Scales of Early Learning (MSEL) were adapted to eliminate the confounding effects of FM…

The genetic diversity contained in a population can be used to engage the audience in an understanding of human genotypes and phenotypes. With a series of simple examples of well-documented sensory phenotypes related to the perception of colour, aromas or food preference, the diversity of the audience can be easily explored. The collecting of…

Purpose: We advanced a multifactorial, dynamic account of the complex, nonlinear interactions of motor, linguistic, and emotional factors contributing to the development of stuttering. Our purpose here is to update our account as the multifactorial dynamic pathways theory. Method: We review evidence related to how stuttering develops, including…

Global university rankings have become increasingly important "calculative devices" for assessing the "quality" of higher education and research. Their ability to make characteristics of universities "calculable" is here exemplified by the first proper university ranking ever, produced as early as 1910 by the American…

Circular dichroism (CD) has emerged as one of the standard biophysical techniques for the study of guaninequadruplex (G4) folding, cation effect, and ligand binding. The utility of this technique is based on its robustness, ease of use, and requirement of only small quantities of nucleic acid. This experiment is also extendable to the classroom…

Although a genetic evaluation can identify the etiology in 15-30% of individuals with autism spectrum disorder, several studies show an underuse of genetic services by affected families. We have explored the access to genetic services and perception of genetics and recurrence risk in parents of autistic children in Spain. Despite the high interest…

Prader-Willi syndrome (PWS), a neurodevelopmental disorder primarily characterized by hyperphagia and food preoccupations, is caused by the absence of expression of the paternally active genes in the proximal arm of chromosome 15. Although maladaptive behavior and the cognitive profile in PWS have been well characterized, social functioning has…
