MGED comes of age

Migration comes of age

The Age of Migration has been uniquely successful as a student text on international migration, not only filling a niche but defining the field. This review article documents the evolution of the five editions of the book in terms of its core structure and enlarging scope. In a more critical vein, I note some omissions and potential shortcomings, while acknowledging the subjectivity of my perspective. More attention could have been given to the mobilities paradigm, transnationalism, internal and return migration, and quantitative analyses. Nevertheless, this book has done more than any other to ensure that the academic study of migration now occupies a central place in the social sciences.     

Immunoinformatics comes of age

With the burgeoning immunological data in the scientific literature, scientists must increasingly rely on Internet resources to inform and enhance their work. Here we provide a brief overview of the adaptive immune response and summaries of immunoinformatics resources, emphasizing those with Web interfaces. These resources include searchable databases of epitopes and immune-related molecules, and analysis tools for T cell and B cell epitope prediction, vaccine design, and protein structure comparisons. There is an agreeable synergy between the growing collections in immune-related databases and the growing sophistication of analysis software; the databases provide the foundation for developing predictive computational tools, which in turn enable more rapid identification of immune responses to populate the databases. Collectively, these resources contribute to improved understanding of immune responses and escape, and evolution of pathogens under immune pressure. The public health implications are vast, including designing vaccines, understanding autoimmune diseases, and defining the correlates of immune protection.

Bacterial secretion comes of age

Bacterial secretion systems play essential roles in pathogenesis and also in maintaining lines of communication between bacterial cells in the bacterial microflora or between commensal bacteria and their host. Recent breakthroughs in the field have yielded some novel insights into the mechanisms by which these systems operate. This issue of Philosophical Transactions B seeks to provide a detailed survey of the field, with an emphasis on mechanisms and how their unravelling might provide a new future for antibiotics research.     

Epigenome sequencing comes of age

Epigenetic states are responsive to developmental and environmental signals, and as a consequence a eukaryotic cell can have many different epigenomes. In this issue of Cell, Lister et al. (2008) present the floral epigenome of Arabidopsis using next-generation sequencing technology to analyze both DNA methylation at single-base resolution and the expression of small RNAs.
