This article describes the conversion of a lecture-based molecular biology course into an active learning environment in a studio classroom. Specific assignments and activities are provided as examples. The goal of these activities is to involve students in collaborative learning, teach them how to participate in the learning process, and give…

Clinical physiologists in Sweden are physicians (the majority with a PhD degree) with thorough training in system physiology and pathophysiology. They investigate patients in a functional approach and are engaged in basic and applied physiology teaching and research. In 1954, clinical physiology was founded as an independent academic and clinical…

Explains the adaptations to Antarctic waters that Notothenioidei, a group of advanced bony fishes, have exhibited. Discusses the fishes' mechanisms of production of antifreeze properties and their capacities for neutral buoyancy in water. (ML)

Discusses the work of evolutionary biologists in determining how sexual reproduction arose. Topics explored include the nature of sex, bacterial sex, meiotic sex, and asexual reproduction. A diagram (which can be used as a duplicating master) illustrating types of bacterial sex is included. (DH)

Presents 11 statements from the American Association of Physical Anthropologists (AAPA) as revisions of the 1964 United Nations Educational, Scientific, and Cultural Organization (UNESCO) statement on race. (YDS)

Addresses claims by Ackles and Karrer (1991) that the neurophysiological evidence used to support Dannemiller and Banks' selective adaptation model of early infant habituation (1983) fails to do so. Some evidence that has emerged since 1983 shows that some aspects of habituation during early infancy cannot be explained by appealing to selective…

Information on bats is provided, focusing on their diversity and distribution, characteristics, food habits, activities, roosting and social habits, reproduction, number of young and size at birth, hibernation, mortality and longevity, and movements and navigation. Additional information related to public health/disease concerns and bat management…

The effects of exercise on hormones in men are described. (MT)

During the last hundred years, the debate over the meaning of race has retained a highly consistent core, despite evolution of the technical details. Non-Europeans, and in particular, Africans, are assigned the role of deviants and outcasts, whose claim on our common humanity remains in doubt. Each time the technical facade of these racialist…

The board that advises the Secretary of HEW on ethics has given a qualified approval for further review of federal funding for research on human embryos conceived in the laboratory. Issues and concerns that influenced the board's decision are addressed. (JMD)

Discusses the divergence of apes from the Old World monkeys and the later divergence of humans from apes. Contrasts current views with those held approximately five years ago. Topics considered include hominoid evolution, hominoid radiation, dryomorphs and ramamorphs, appearance of the first hominids, and adaptive radiation of these hominids. (JN)

A critic of science identifies the ground from which emanate toys, games, and inventive play. The knowledge and other prerequisites characterizing the inventor of pastimes are examined, touching on the correspondence existing between the biological/physical sciences and games/inventions. (Author/JN)

Researchers have recently begun to use the tools of neuroscience to examine the social psychological responses associated with race. This article serves as a review of the developing literature in this area. It advances the argument that neuroscience studies of race have the potential to shape fundamental assumptions about race, and the interplay…

"Eukiefferiella" and "Tvetenia" are closely related genera belonging to the subfamily Orthocladiinae within the Chironomidae, a family of non-biting midges. All known larvae in these genera are aquatic, being found predominantly in running water. Most species prefer cold, swift-flowing, well-oxygenated streams. Although larvae…

Constructs an evolutionary sequence to account for the diversity of ion pumps found today. Explanations include primary ion pumps in bacteria, features and distribution of ATP-driven pumps, preference for cation transport, and proton pump reversal. The integrated evolutionary hypothesis should encourage new experimental approaches. (DH)
