Direct linkKoenig, Laura B.; McGue, Matt; Iacono, William G. – Developmental Psychology, 2008
Understanding the development of religiousness is an important endeavor because religiousness has been shown to be related to positive outcomes. The current study examined mean-level, rank-order, and individual-level change in females' religiousness during emerging adulthood. Genetic and environmental influences on religiousness and its change and…

Deutch, Charles E.; Marshall, Pamela A. – American Biology Teacher, 2008
In this article, the authors describe an interconnected set of relatively simple laboratory experiments in which students determine the RNA content of yeast cells and use agarose gel electrophoresis to separate and analyze the major species of cellular RNA. This set of experiments focuses on RNAs from the yeast "Saccharomyces cerevisiae", a…

Todd, Jude – American Indian Quarterly, 2008
Scientists are not sure of how corn was created. There were two competing genetic theories about how corn came to be. One theory maintains that corn had been teased out of a wheatlike grass called teosinte (genus Zea), and the other contends that one now-extinct ancestor of corn had crossed with another grass, "Tripsacum," several millennia ago.…

Szeberenyi, Jozsef – Biochemistry and Molecular Biology Education, 2008
Mutational inactivation of a specific gene is the most powerful technique to analyze the biological function of the gene. This approach has been used for a long time in viruses, bacteria, yeast, and fruit fly, but looked quite hopeless in more complex organisms. Targeted inactivation of specific genes (also known as knock-out mutation) in mice is…

Peppink, D.; Douma-Kloppenburg, D. D.; de Rooij-Askes, E. S. P.; van Zoest, I. M.; Evenhuis, H. M.; Gille, J. J. P.; van Hagen, J. M. – Journal of Intellectual Disability Research, 2008
Background: Determining the aetiology of intellectual disability (ID) enables anticipation of specific comorbidity and can thus be beneficial. Blood sampling, however, is considered stressful for people with ID. Our aim was to evaluate the feasibility of a non-invasive screening technique of nine microdeletions/duplications among adults with ID of…

Barnett, Kylie J.; Finucane, Ciara; Asher, Julian E.; Bargary, Gary; Corvin, Aiden P.; Newell, Fiona N.; Mitchell, Kevin J. – Cognition, 2008
The term synaesthesia has been applied to a range of different sensory-perceptual and cognitive experiences, yet how these experiences are related to each other is not well understood. Not only are there disparate types of synaesthesia, but even within types there are vast individual differences in the way that stimuli induce synaesthesia and in…

Price, Johanna R.; Roberts, Joanne E.; Hennon, Elizabeth A.; Berni, Mary C.; Anderson, Kathleen L.; Sideris, John – Journal of Speech, Language, and Hearing Research, 2008
Purpose: This study compared the syntax of boys who have fragile X syndrome (FXS) with and without autism spectrum disorder (ASD) with that of (a) boys who have Down syndrome (DS) and (b) typically developing (TD) boys. Method: Thirty-five boys with FXS only, 36 boys with FXS with ASD, 31 boys with DS, and 46 TD boys participated. Conversational…

Kolata, Stefan; Light, Kenneth; Matzel, Louis D. – Intelligence, 2008
It has been established that both domain-specific (e.g. spatial) as well as domain-general (general intelligence) factors influence human cognition. However, the separation of these processes has rarely been attempted in studies using laboratory animals. Previously, we have found that the performances of outbred mice across a wide range of…

Dolan, Erin L.; Lally, David J.; Brooks, Eric; Tax, Frans E. – Science Teacher, 2008
In this article, the authors describe a large-scale research collaboration, the Partnership for Research and Education in Plants (PREP), which has capitalized on publicly available databases that contain massive amounts of biological information; stock centers that house and distribute inexpensive organisms with different genotypes; and the…

Case, Emily – American Biology Teacher, 2008
Taxonomy, the identification, naming, and classification of living things, is an indispensable unit in any biology curriculum and indeed, an integral part of biological science. Taxonomy catalogues life's diversity and is an essential tool for communication. Textbook discussions of taxonomy range anywhere from three to eight domains of kingdoms.…

Campbell, Dennis J.; Reilly, AmySue; Henley, Joan – Education and Training in Developmental Disabilities, 2008
This paper describes a research study that assessed young children with a low incidence disability, specifically Cri-du-Chat Syndrome (CDSC). A description of the concerns of assessing individuals with low incidence disabilities is described. Parent reports (using the Development Observation Checklist System) on the functioning of their children…

Gelinas, Jennifer N.; Tenorio, Gustavo; Lemon, Neal; Abel, Ted; Nguyen, Peter V. – Learning & Memory, 2008
Activation of Beta-adrenergic receptors (Beta-ARs) enhances hippocampal memory consolidation and long-term potentiation (LTP), a likely mechanism for memory storage. One signaling pathway linked to Beta-AR activation is the cAMP-PKA pathway. PKA is critical for the consolidation of hippocampal long-term memory and for the expression of some forms…

Phenotypical Characteristics of Idiopathic Infantile Nystagmus with and without Mutations in "FRMD7"
Thomas, Shery; Proudlock, Frank A.; Sarvananthan, Nagini; Roberts, Eryl O.; Awan, Musarat; McLean, Rebecca; Surendran, Mylvaganam; Kumar, A. S. Anil; Farooq, Shegufta J.; Degg, Chris; Gale, Richard P.; Reinecke, Robert D.; Woodruff, Geoffrey; Langmann, Andrea; Lindner, Susanne; Jain, Sunila; Tarpey, Patrick; Raymond, F. Lucy; Gottlob, Irene – Brain, 2008
Idiopathic infantile nystagmus (IIN) consists of involuntary oscillations of the eyes. The familial form is most commonly X-linked. We recently found mutations in a novel gene "FRMD7" (Xq26.2), which provided an opportunity to investigate a genetically defined and homogeneous group of patients with nystagmus. We compared clinical features and eye…

Chin, Christine; Teou, Lay-Yen – Journal of Biological Education, 2010
This study was carried out in the context of formative assessment where assessment and learning were integrated to enhance both teaching and learning. The purpose of the study was to: (a) identify pupils' ideas about biological inheritance through the use of a concept cartoon, pupils' drawings and talk, and (b) devise scaffolding structures that…
