The cognitive and behavioral symptoms of nonverbal learning disabilities (NLD) have been described by previous investigators. Nevertheless, we know far less about the potential genetic contributions that may predispose a child to have NLD. An endophenotype model was investigated in 5 samples of children ages 9 to 15 years: NLD (n = 32); reading…

In this article we discuss the traditional behavioral models of depression and some of the challenges analyzing a phenomenon with such complex and varied features. We present the traditional model and suggest that it does not capture the complexity of the phenomenon, nor do syndromal models of depression that dominate the mainstream…

A one day practical course in molecular biology skills suitable for year 12/13 students is described. Colleagues from partner schools and colleges were trained by university staff in basic techniques and then collaborated in the design of a course suitable for their own students. Participants carried out a transformation of "E.coli"…

The prototype of a guided practice application was developed to instruct year 13 biology students in the process of DNA replication. The application uses a high degree of interaction to engage the student in a guided exploration and problem solving exercise. An evaluation revealed that the students showed considerable enthusiasm and significant…

This research addresses the effectiveness of an interactive learning environment, Inquiry Island, as a general-purpose framework for the design of inquiry-based science curricula. We introduce the software as a scaffold designed to support the creation and assessment of inquiry projects, and describe its use in a middle-school genetics unit.…

Genome science, including topics such as gene recombination, cloning, genetic tests, and gene therapy, is now an established part of our daily lives; thus we need to learn genome science to better equip ourselves for the present day. Learning from topics directly related to the human has been suggested to be more effective than learning from…

The main argument of this article is that human living systems are open, dynamic, intentional systems and, therefore, are capable of building ever more complex behaviors through self-organization and self-direction. This principle underlying general human development is also applicable to the development of gifted and talented behaviors. These…

We have developed and optimized the necessary laboratory materials to make DNA microarray technology accessible to all high school students at a fraction of both cost and data size. The primary component is a DNA chip/array that students "print" by hand and then analyze using research tools that have been adapted for classroom use. The…

Protein synthesis-dependent long-term memory in Apis mellifera and Drosophila melanogaster is formed after multiple trainings that are spaced in time. The parasitic wasp Lariophagus distinguendus remarkably differs from these species. It significantly responds to the artificial odor furfurylheptanoate (FFH) in olfactometer experiments, when this…

Research in psychiatric genetics shows that many mental disorders commonly seen by counselors are associated with the presence of specific genes. Although findings in gene research call for some changes in the way counselors approach intervention, in most cases, the importance of the counseling profession's core commitments is underscored. This…

Neanderthals, those long-lost cousins of modern humans, will not remain lost for long, at least from the prying eyes of geneticists. Two teams of scientists announced that for the first time they had analyzed DNA from the nuclei of cells preserved in 37,000-year-old Neanderthal fossils. That, they say, lays the groundwork for determining the…

The isotopic distribution in mass spectroscopy is described for identifying pure compounds, being able to distinguish molecular fragments by masses. Punnett squares are familiar, easy to compute, and often graphical which makes helpful to students and the relative distribution of isotopic combination is easily generated for even isotopic…

The need for the development of a biotechnician curriculum was investigated. A search for operational job descriptions for biotechnicians was conducted. Industry consensus was that this is a generic term too broad to be useful. Biotechnology companies within a 300-mile radius of Chicago and universities and other colleges in Illinois that hire…

Discusses the role of the fruit fly in genetics research requiring a multidisciplinary approach. Describes embryological and genetic methods used in the experimental analysis of this organism. Outlines the use of Drosophila in the study of the development and function of the nervous system. (RT)

Describes three methods and their advantages and disadvantages for introducing genes into animals. Discusses the predictability and tissue-specificity of the injected genes. Outlines the applications of transgenic technology for studying gene expression, the early stages of mammalian development, mutations, and the molecular nature of chromosomes.…
