Describes a project where students were given a small but real scientific question and allowed to deal with all aspects of the project just as a professional scientist would, rather than work on the science part only. (JRH)

A quantitative study of the fauna of a garden compost heap shows it to be similar to that of organisms found in soil and leaf litter. Materials, methods, and results are discussed and extensive tables of fauna lists, wet/dry masses, and statistical analyses are presented. (Author/DH)

Reviews current findings that explain RNA's function as an enzyme in addition to being an informational molecule. Highlights recent research efforts and notes changes in the information base on RNA activity. Includes models and diagrams of RNA activity. (ML)

Describes a collaborative project by a tropical ecologist, an ant expert, and a biology teacher to explore insect herbivory in the rainforest canopy. (MKR)

Examines research related to the retina's coding of visual input with emphasis on the organization of two kinds of ganglion cell receptive fields. Reviews current techniques for examining the shapes and arrangement in the retina of entire populations of nerve cells. (ML)

Explains an experiment in which the rotation of a patch of skin on a tadpole results in a frog with rotated spots, proving that the spot pattern is determined long before it becomes visible. Procedures used are included. (DH)

Updates knowledge on nitrogen fixation, indicating that investigation of free-living nitrogen-fixing organisms is proving useful in understanding bacterial partners and is expected to lead to development of more effective symbioses. Specific areas considered include biochemistry/genetics, synthesis control, proteins and enzymes, symbiotic systems,…

Lists informal definitions for 130 terms dealing with recombinant DNA research. (CS)

Discusses the irregularity and unpredictability of the human body. Presented are pictures showing the fractallike structures and research findings on the mechanism for chaos in the human body. Lists four further reading materials. (YP)

High school students discuss the process of conducting original scientific research in a high school biology course, including developing an idea, obtaining financial support, collecting data, and presenting findings. (MKR)

These proceedings of a symposium designed to increase public awareness of current research in biology and biotechnology include: welcoming addresses by Chau Sian Eng and S. Radhakrishna; an opening address by Tay Eng Soon; five papers; four abstracts; summary; symposium program; and list of participants. The five papers are: (1) "The Role of…

This article describes how Robert LeBleu's interest in aquatic life developed and that today he owns a large hydroculture operation supplying research crayfish nationwide. Suggested laboratory experiments with crayfish are described, as well as information on additional studies, equipment needs, and tours of the hatchery. (MA)

Introductory biology students at a major university completed a field project which taught them investigative skills in scientific research, including the scientific method and substantiation of their results through use of periodical literature. Librarians became actively involved by providing library instruction as part of the project. Sample…

Describes the experimental procedure and expected outcome in the growth of rice seedlings with light conditions and water aeration as variables. (GS)

Describes the use of James Watson's book, "The Double Helix," as a multidisciplinary way of introducing students to actual science; the scientific method; dilemmas encountered in the world of research; and the rich setting of personalities, politics, and history in post-World War II Europe. (MKR)
