The purpose of this study is to contribute to a theoretical knowledge base through research by examining factors salient to science education reform and practice in the context of socioscientific issues. The study explores how individuals negotiate and resolve genetic engineering dilemmas. A qualitative approach was used to examine patterns of…

"Chronicle of Higher Education" presents an abundant source of news and information for college and university faculty members and administrators. This June 4, 2004 issue of "Chronicle of Higher Education" includes the following articles: (1) "What Has Happened to Historical Literacy?" (Rabb, Theodore K.); (2)…

Some aspects of biology, for example the Hardy-Weinberg simulation of population genetics or modelling heat flow in lizards, have an undeniable mathematical basis. Students can find the level of mathematical skill required to deal with such concepts to be an insurmountable hurdle to understanding. If not used effectively, spreadsheet models…

Background: Individuals with early warning signs of life-long psychopathy, callous-unemotional traits (CU) and high levels of antisocial behaviour (AB) can be identified in childhood. We report here the first twin study of high levels of psychopathic tendencies in young children. Methods: At the end of the first school year, teachers provided…

Background: Although DSM-IV requires symptoms in three criterion domains for a diagnosis of autistic disorder, the extent to which those domains are phenotypically independent is an unanswered and important question. The identification of "endophenotypes" of the autistic syndrome may be very useful for genetic and neurobiologic studies of autism,…

Background: This study examines the diagnostic accuracy of the CBCL syndrome AS scales for predicting DSM-IV Attention Deficit-Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder with or without Conduct Disorder (ODD/CD). Methods: The sample included 370 children (187 probands and 183 siblings) participating in a family genetic study…

Lennox-Gastaut (L-G) syndrome is an intractable generalized epilepsy of childhood onset, associated with spike waves at a slow rate and paroxysmal fast activity. These epileptiform discharge patterns are thought to reflect excessive neocortical excitability and arise from neuronal and synaptic features peculiar to the immature central nervous…

Studies on human patients and animal models of disease have shown that disruptions in prenatal and early postnatal brain development are a root cause of mental retardation. Since proper brain development is achieved by a strict spatiotemporal control of neurogenesis, cell migration, and patterning of synapses, abnormalities in one or more of these…

This article takes issue with the behavior-genetic analysis of parenting style presented by M. McGue, I. Elkins, B. Walden, and W. G. Iacono. The author argues that the attribution of their findings to inherited genetic effects was without basis because McGue et al. never indicated how those genetic effects manifested themselves. Instead, McGue et…

At the 102nd annual meeting of the American Society for Microbiology (ASM) in Salt Lake City, Utah, members of the Genome Consortium for Active Teaching and faculty from around the world gathered to discuss educational genomics. The focus of the gathering was a series of presentations by faculty who have successfully incorporated genomics and…

A 14-week, undergraduate-level Genetics and Population Biology course at Morgan State University was modified to include a demonstration of functional genomics in the research laboratory. Students performed a rudimentary sequence analysis of the "Caenorhabditis elegans" genome and further characterized three sequences that were predicted to encode…

On April 25, 1953, three papers were published in "Nature," the prestigious scientific journal, which exposed the "fundamentally beautiful" structure of DNA to the public, and sounded the starting gun of the DNA Revolution. The authors of these papers revealed the now-famous double-helix structure of DNA, thereby unlocking the…

Nonscience majors often do not respond to traditional lecture-only biology courses. However, these students still need exposure to basic biological concepts. To accomplish this goal, forensic science was paired with compatible cell biology subjects. Several topics such as human development and molecular biology were found to fulfill this purpose.…

This study of 4,274 pairs of 4-year-old twins from the Twins Early Development Study explored the magnitude of genetic and environmental effects on low expressive vocabulary skill, both as a function of general cognitive ability and as a function of the severity of expressive vocabulary impairment. Assessments were conducted through parent report…

This article describes a course for nonscience majors that uses the issue of race in humans to stimulate interest in genetics and other sciences. Student outcomes, including valuing and understanding science, plus an ability to discuss the sensitive issue of race, are very positive.
