Because of its biological adaptive value, wariness of heights is widely believed to be innate or under maturational control. In this report, we present evidence contrary to this hypothesis, and show the importance of locomotor experience for emotional development. Four studies bearing on this conclusion have shown that (1) when age is held constant, locomotor experience accounts for wariness of...

DAVIDA RUBIN (comp.), Sir Kenelm Digby F.R.S. (1603-1665): a bibliography based on the collection of K. Garth Huston, Sr., M.D., San Francisco, Jeremy Norman, 1991, pp. xvi, 130, illus., $95.00 (0-930405-29-3). Having forgiven his significant contribution to quackery-the promotion of an infamous "powder of sympathy" that healed without coming into contact with the wound-historians in this centu...

BACKGROUND The comparison of human related communication skills of socialized canids may help to understand the evolution and the epigenesis of gesture comprehension in humans. To reconcile previously contradicting views on the origin of dogs' outstanding performance in utilizing human gestures, we suggest that dog-wolf differences should be studied in a more complex way. METHODOLOGY/PRINCIPA...

How cell and tissue interactions lead to complex organ structures and differentiated cell types during organogenesis is one of the most fundamental questions in developmental biology. The embryonic lung and kidney of the mouse are useful models for studying the molecular mechanisms of morphogenesis, and in both of these organs, the epithelial bud undergoes a characteristic branching process. Th...

This book contains thirty-seven chapters, each a largely self-contained essay on some aspect of the quantitative method in biology and medicine. The first eight of these deal specifically with historical topics and include commentaries, for example, on Harvey's discovery of the circulation of the blood, Mendel's basic theories and experimental findings, immunity against smallpox, the prevention...

strictly European. This classification has certainly given her difficulties in writing her narrative histories but it lends itself readily enough to a bibliography. Perhaps the structure leaves too little to chance. It is odd to find Buffon and Walter Charleton bracketed in the same time span ('Biologists in the seventeenth and eighteenth centuries') and counter-intuitive to search for Blumenba...

A lthough neurohormonal antagonist and device therapies have improved outcomes in patients with systolic heart failure (HF), residual morbidity and mortality remain high. Novel HF therapeutic approaches thus remain an unmet clinical need of pressing urgency. Such approaches depend, in turn, on keener understanding of the molecular pathways underlying HF pathogenesis. Although a number of novel ...
