The Effects of Antibiotics on Bacterial Growth
[ send me this paper ]
A 5 page discussion of bacterial growth in the presence of antibiotics. Examines how bacterial growth is dependent on a number of their physiological mechanisms such as enzymes, proteins, and even the communication of one organism with another in a phenomenon referred to as quorum sensing. Emphasizes that it is critical to continue our quest to understand the specifics of how antibiotics influence bacterial growth. By improving our understanding and concentrating on developing antibiotics which only work on specific intracellular functions of bacteria we have a higher chance of improving the long-term health not only of human populations but also of those populations of plants and animals upon which we depend.

The Evolution of Teeth
[ send me this paper ]
A 10 page outline of the evolution of teeth from the lower vertebrates to more advanced species such as man. Describes the origin of jaw structure and structures such as conodonts (minute toothlike structures) which were the precursors of advanced teeth. Outlines the further evolution of these teeth in the higher mammals with the appearance of features like the hypocone which expanded the grinding surface of teeth and resulted in an explosion of mammal species some forty thousand years ago. Bibliography lists 8 sources.

The Game of Chess and Cognitive Development
[ send me this paper ]
A 7 page discussion of the importance of chess. Chess is much more than a game. It can be contended, in fact, that chess can be of benefit to cognitive development and learning. Cognitive learning is the process in which knowledge is acquired. It involves an individual being cognizant of his or her environment and gaining knowledge from that environment. This involves both thinking and problem solving which in turn results in memory formation and learning. In order to learn how to play chess an individual must be able to both form memories and to learn how to correctly plan their moves. Chess is instrumental in both the physiology of this development as well as in the social aspects of cognitive development. Bibliography lists 20 sources.

The Genetic Pathway and Developmental Evolution
[ send me this paper ]
A 7 page discussion of genetic pathways, specifically the direction of the orderly expression of specific gene subsets, a process which is controlled by tissue-specific transcription factors. Specific DNA target sequences are bound by these transcription factors and, in turn, interact with one another on either a cooperative basis or an antagonistic basis to control expression of the gene subsets. This interaction is aided as well by extracellular signaling molecules which both control and are controlled by the transcription factors. Ties these basic observations together with a review of research on species as diverse as Drosophila melanogaster and zebrafish. An additional 2 pages are appended on this paper which identify several references which could be applicable in an expanded review of this subject. Bibliography lists 13 sources.
