TSAI, P.-S.*; MALDONADO, T.A.; PAK, T.R.; ZHANG, L.: Characterization of a Gonadotropin-Releasing Hormone System in an Opisthobranch Mollusk, Aplysia californica Gonadotropin-releasing hormone (GnRH) is a neurohormone crucial for the regulation of reproductive and neural functions in vertebrates. Recent discoveries of GnRH immunoreactivity (IR) in a number of invertebrates raised the possibility that GnRH may be […]

Muscle as Engine A Biomechanical Look at Some Ancient Tasks
VOGEL, S. : Muscle as Engine: A Biomechanical Look at Some Ancient Tasks Using muscle to power large-scale tasks presents specific difficulties. For instance, the relatively uniform size of people and draft animals imposes problems of scaling, and muscle’s inability to produce rotary motion means that non-functional mass must be accelerated and decelerated. Thus (1) […]
Evo versus Devo Methodological Conflicts in the Treatment of Variation
AMUNDSON, R.: Evo versus Devo: Methodological Conflicts in the Treatment of Variation Evolutionary and developmental biology were independent enterprises for most of the twentieth century. Differences in goals led to differences and even inconsistencies in methodologies and practices. One of the tasks of an integrative program of evolutionary developmental biology will be to negotiate these […]
Cultural evolution of scientific values grant overhead in a parasite-host model
EDWARDS, R.: Cultural evolution of scientific values: grant overhead in a parasite-host model. From 1968 to 1992, basic science in the United States experienced an economic condition so pervasive and significant that it was rarely acknowledged to occur. During this period, “grant overhead,” or the requested percent by which a grant budget was increased, was […]
Integration of Research and Education Are you ready
ADELMAN, L.M.: Integration of Research and Education: Are you ready? Have you seen the new NSF guidelines? “One of the principal strategies in support of NSF’s goals is to foster integration of research and education through the programs, projects, and activities it supports at academic and research institutions. …NSF is committed to this principle of […]
Incorporating digital media and new technologies into an Introductory Zoology course Experiences and Reflections
HOUSEMAN, J. G. *: Incorporating digital media and new technologies into an Introductory Zoology course: Experiences and Reflections. This paper reports on seven years of personal experience on using digital media and new technologies for teaching Introductory Zoology, and looks back on some of the things that worked along with some that didn’t. University of […]
Building Conceptual Frameworks for Teaching Biology and Physiology Theory, Examples and a New Role for SICB
STEVENSON, R.D.: Building Conceptual Frameworks for Teaching Biology and Physiology: Theory, Examples and a New Role for SICB? A recent publication from the National Academy Press titled “How People Learn: Bridging Research and Practice” by Donovan et al. (http://books.nap.edu/html/howpeople2/ch1.html) highlights several ways to improve teaching and learning. The report states that deep factual knowledge, a […]
Applying what you learned in CLASS Transforming biological laboratory education so that it is universally accessible
WHEATLY, M.G.*; WOOD, T.J.; RENICK, P.; VERNOOY, J.; TASCHENBERGER, L.; WENDELN, M.: Applying what you learned in CLASS: Transforming biological laboratory education so that it is universally accessible. Creating Laboratory Access for Science Students (The CLASS Project) is an NSF-funded initiative to train educators to develop lab exercises and field trips that are universally accessible […]
Animal Magnetism Using magnetic stir bars to learn about digestive passage rate in snakes
Temple, J. G.: Animal Magnetism: Using magnetic stir bars to learn about digestive passage rate in snakes. Snakes, as classic ectotherms, are interesting subjects for studying the relationship between temperature and physiological processes. They are particularly well-suited for studying digestive passage rate given the linear anatomical arrangement of their digestive tracts. In this paper, a […]
AIBSPackard Review of High School Biology Instructional Materials
MORSE, M.P.: AIBS/Packard Review of High School Biology Instructional Materials Ten sets of instructional materials currently used in high school biology courses across the nation were reviewed by a 9-person team of scientists, science educators and teachers. This team developed the AIBS/Packard review instrument and conducted the review over a period of 18 months. The […]
