Endothelio-hematopoietic relationship: getting closer to the beginnings
Sabrina Gordon-Keylock, Alexander Medvinsky BMC Biology 2011, 9:88 (28 December 2011)
Abstract | Full text | PDF
| PubMed
|
Editor’s summary
Both blood cells and vascular cells can differentiate from a single precursor cell, the hemangioblast. But what is the origin of the hemangioblast? Gordon-Keylock and Medvinsky discuss a new method of labeling these cells, reported by Ana T Tavares and colleagues, that may provide an answer.

Multiple origins of endosymbiosis within the Enterobacteriaceae (γ-Proteobacteria): convergence of complex phylogenetic approaches
Filip Husník, Tomáš Chrudimský, Václav Hypša BMC Biology 2011, 9:87 (28 December 2011)
Abstract | Full text | PDF
| PubMed | Cited on BioMed Central
|
Editor’s summary
Symbiosis is assumed to be a rare event, but a sophisticated evolutionary analysis picks apart the history of endosymbiosis between bacteria and insects and shows that in contrast to a single origin, symbiosis in this context has independently evolved a number of times.

Abstract | Full text | PDF
| PubMed | Cited on BioMed Central

Editor’s summary
The festering discontent with reviewing and editorial practices in the high-profile biology journals has erupted into a new high-quality open access journal to be launched in 2012. Miranda Robertson explores the problem and the solutions offered, and revisits the re-review opt-out policy operated by BMC Biology.
