Basic architecture of embryo development appears to be under homeobox control (a short stretch of DNA). Outlines research on this genetic segment in fruit flies which led to identification of this control on the embryo's spatial organization. Indicates that molecular mechanisms underlying development may be much more universal than previously…

Discusses the unique user interface of Apple's Macintosh microcomputer which is changing the way researchers interact with their data. Topic areas addressed include: desktop, mouse, and windows; preparing scientific illustrations; MacPaint; and charts and graphics. Limitations are also noted. (DH)

Presented is a review of the history of the discovery of gene function, and description of the research and scientists responsible for each major step in the sequence of discoveries. A brief review of the current status of the research is included. (SL)

The agencies listed in this document are amending the Federal Policy for the Protection of Human Subjects, which was published in the Federal Register on June 18, 1991, to change all references to the Office for Protection from Research Risks (OPRR) to the Office for Human Research Protections (OHRP); revise the footnote found at the end of…

Describes techniques and results of a study on leaves of a leguminous tree. (PS)

Advocates that some established botanists should become involved in social and political problems to which botanical expertise is relevant. Discusses food production in relation to world population growth, indicating problems on which botanical knowledge and research should be brought to bear. Discusses herbicides and plant growth regulators as…

Highlights major activities, conferences, conference and published papers, monographs, and research studies in paleobotany during 1982. Indicates that paleobotanists made more frequent use of the perspectives and ideas of disciplines as developmental biology and sedimentology in their research endeavors. (Author/JN)

Reviews the pros and cons of using animals or alternatives in scientific research. Such alternatives (as indicated in congressional bill HR 556) include mathematical models, isolated organs, tissue and cell cultures, computer simulations, mechanical models, and "lower" organisms among others. (SK)

Describes recent research by Edward Steele appearing to support the Lamarckian theory of inheritance. Steele suggests that a mutant somatic cell favored by the environment will undergo clonal expansion. Altered genetic materials from these cells is then picked up by C-type viruses and inserted into the germ line genome. (CS)

Reviews creationist arguments attacking scientific evidence for evolution and an old earth, presenting counter-arguments from the evolutionist's point of view. (CS)

This article on the brain is part of an entire issue about neurobiology and the question of how the human brain works. The brain as an intricate tissue composed of cells is discussed based on the current knowledge and understanding of its composition and structure. (SA)

The neuron, called the building block of the brain, is discussed with regard to structure and function. (Author/SA)

The organization of the billions of neurons within the brain and spinal cord of mammals is discussed. (Author/SA)
