A simple bioassay was designed for the detection of adenosine, a human metabolite involved in several physiological processes, on the basis of the functionalization of gold nanoparticles with DNA oligonucleotides selectively binding adenosine. The test was possible thanks to the selective and sensitive binding of adenosine by two DNA…

The controversy and uncertainty surrounding use of nanosilver in consumer products can be used to stimulate a question-based discussion that integrates ethical and social implications with biology.

This article presents an experiment designed to provide students, in a classroom laboratory setting, a hands-on demonstration of the steps used in DNA forensic analysis by performing DNA extraction, DNA fingerprinting, and statistical analysis of the data. This experiment demonstrates how DNA fingerprinting is performed and how long it takes. It…

Integrating advanced biological techniques into instruction at non-R1 institutions can prove to be a challenge. Here, we report the creation of a model for the introduction of gene expression microarray technology into a research laboratory. A student assessment tool was used to evaluate: (1) technical skill development; (2) cross-disciplinary…

This article features Ohio teacher Carol Fleck's use of videoconferencing in teaching Contemporary BioScience and Genetics. Fleck, who says her initial vision for the class was "science without classroom walls," covers such topics as emerging diseases, bioterrorism, and forensic science. Collaboration between schools is a key part of the…

Presents examples using biotechnology applications to clarify topics in genetics, such as DNA replication, gene segregation and polar bodies, multiple alleles, and antisense sequences. (MKR)

Discusses a three-week summer college honors course for talented high school juniors with three exams, lab six days a week, a research paper, field trips, and student panel discussions. Presents an overview of the course. Describes the lab which uses "E. coli" for DNA recombination. (MVL)

Explains the potential of computer technology in science education and argues for integrating bioinformatics into the biology curriculum. Describes three modules designed to introduce students to technological advancements in biology. Aims to develop a better understanding of molecular biology among students. (YDS)

Discusses strategies that enable students to learn ideas and concepts in the context of how modern communication technology is designed and operates. Describes a course that integrates the study of math, science, and technology into topics that are engaging to students. Presents an activity that introduces students to digital coding and compares…

This curriculum guide was developed with the intention of providing an enrichment option for gifted and talented learners who are interested in pursuing current issues and topics in the fields of mathematics and science. The scope of the guide is meant to encompass a year's study of a set of topics which apply mathematics to science and…

Provides reviews of modular materials that contain a Science, Technology, Society (STS) theme. Specifies the criteria and distinguishing features of STS materials. Includes reviews of programs which address the topics of energy, genetics, human reproduction, and recombinant DNA research. (ML)
