The Genome Sequence of Taurine Cattle: A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

A tradução química de experimentos alquímicos envolvendo água régia em Robert Boyle

Recentemente, alguns acadêmicos têm demonstrado que a tradução química pode auxiliar o trabalho histórico. O objetivo deste trabalho é traduzir alguns experimentos alquímicos de Robert Boyle para a química contemporânea, particularmente, aqueles que envolvem a água régia. A maior parte desses experimentos tem relação com o mecanicismo boyleano, com receitas de produção de compostos e com a padronização de procedimentos químicos. Muitos deles envolvem descrições precisas de propriedades, tais como o ponto de fusão, a mudança de gosto, a liberação de som e bolhas, a corrosão etc., que podem ser usadas como ferramentas de rastreamento para uma tradução à notação química atual.

Estudos sobre o subdesenvolvimento capitalista: as teorias de Paul A. Baran, Andre G. Frank e Ruy M. Marini

The underdevelopment is a high relevance subject in researches and studies for the general social sciences. In this monographic paper, the marxist analysis perspective of the phenomenon approached is considerate of great importance to make a deep overlook, historical and structural, about the origins and solutions possibilities for the issues caused by it over several countries. Has been done here a theoretical analysis of three studious marxist authors of the subject: Paul A. Baran, Andre G. Frank and Ruy M. Marini. How they thought underdevelopment? Which were their scientific contributions to this theme? The main goal of this paper is to do a comparative analysis of these authors, synthesize their considerations about the underdevelopment issues and organized a theoretical and conceptual framework for a better understanding of the matters in capitalist development/underdevelopment relationship. To accomplish that, we elected four variables that supports this comparative exercises, they are: the origins, the causes, the consequences and the way-out of the underdevelopment conditions. This monographic work was made through studies of some principals books and articles of the cited authors as well as the reading of others authors that commented their theories and concepts. The considerations about the underdevelopment vitality under a world capitalist logical, rescues the debate on the transformation of this entire society project for another, been this movement the only way possible to reverse the path of the world people’s history and the major part of humankind that still lives into the “necessity kingdom”

Genomic signatures of evolutionary transitions from solitary to group living

The evolution of eusociality is one of the major transitions in evolution, but the underlying genomic changes are unknown. We compared the genomes of 10 bee species that vary in social complexity, representing multiple independent transitions in social evolution, and report three major findings. First, many important genes show evidence of neutral evolution as a consequence of relaxed selection with increasing social complexity. Second, there is no single road map to eusociality; independent evolutionary transitions in sociality have independent genetic underpinnings. Third, though clearly independent in detail, these transitions do have similar general features, including an increase in constrained protein evolution accompanied by increases in the potential for gene regulation and decreases in diversity and abundance of transposable elements. Eusociality may arise through different mechanisms each time, but would likely always involve an increase in the complexity of gene networks.
