    Summary: This book describes the similarities and differences between two species, bonobos and chimpanzees, based on the three decades the author has spent studying them in the wild, and shows how the contrasting nature of these two species is also reflected in human nature. The most important differences between bonobos and chimpanzees, our closest relatives, are the social mechanisms of coexistence in group life. Chimpanzees are known as a fairly despotic species in which the males exclusively dominate over the females, and maintain a rigid hierarchy. Chimpanzees have developed social intelligence to survive severe competition among males: by upholding the hierarchy of dominance, they can usually preserve peaceful relations among group members. In contrast, female bonobos have the same or even a higher social status than males. By evolving pseudo-estrus during their non-reproductive period, females have succeeded in moderating inter-male sexual competition, and in initiating mate selection. Although they are non-related in male-philopatric society, they usually aggregate in a group, enjoy priority access to food, determine which male is the alpha male, and generally maintain much more peaceful social relations compared to chimpanzees. Lastly, by identifying key mechanisms of social coexistence in these two species, the author also seeks to find solutions or "hope" for the peaceful coexistence of human beings. "Takeshi Furuichi is one of very few scientists in the world familiar with both chimpanzees and bonobos. In lively prose, reflecting personal experience with apes in the rain forest, he compares our two closest relatives and explains the striking differences between the male- dominated and territorial chimpanzees and the female-centered gentle bonobos."

    Laser-Raman spectroscopy of the turnip yellow mosaic virus (TYMV) and its capsid indicate the following features of the structure and assembly of the virion. The secondary structure of coat-protein molecules in TYMV is comprised of 9 +/- 5% alpha-helix, 43 +/- 6% beta-sheet, and 48 +/- 6% irregular conformation and is not altered by the removal of the RNA from the capsid. Introduction of as many as 200 chain scissions per RNA molecule also does not affect the overall secondary structure of the encapsulated RNA, which is 77 +/- 5% in the A-helix form. Tryptophan and cysteine residues of the coat protein appear to be in contact with the solvent, while only one of three tyrosines per coat protein is available for hydrogen bonding of its p-hydroxyl group with H2O molecules. Both cytosine and adenine residues of TYMV RNA are protonated in substantial numbers near pH 4.5, suggesting elevation of their respective pKa values within the virion. The Raman data are consistent with chemical evidence favoring interaction between protonated bases of RNA and amino acid side chains of coat protein in TYMV.
