Sequencing and assembly of the 32-Gb genome of the Mexican axolotl reveals that it lacks the developmental gene Pax3, which is essential in other vertebrates; the genome sequence could improve our understanding of the evolution of the axolotl’s remarkable regenerative capabilities.

An improved genome assembly for Schmidtea mediterranea shows that the genome is highly polymorphic and repetitive, and lacks multiple genes encoding core components of cell biological mechanisms.

Analysis of the light curves of outbursts in black-hole X-ray binaries suggests that throughout the accretion process mass is lost from the accretion disks through strong, magnetically driven disk winds.

Asteroseismic ‘sounding’ reveals the internal chemical stratification of the white dwarf KIC08626021, which has a central homogeneous core—composed of 86 per cent oxygen—that has a mass of 0.45 solar masses.

Analysis of transplantation of single haematopoietic stem cells in mice defines stable lineage-restricted fates in long-term self-renewing multipotent stem cells, including a class of multipotent stem cells that exclusively replenishes the megakaryocyte/platelet lineage.

Mutations associated with Treacher Collins syndrome perturb the subnuclear localization of an RNA helicase involved in ribosome biogenesis through activation of p53 protein, illustrating how disruption in general regulators that compromise nucleolar homeostasis can result in tissue-selective malformations.

Members of a family of marine dsDNA non-tailed bacterial viruses have short, 10-kb genomes, infect a broader range of hosts than tailed viruses and belong to the double jelly roll capsid lineage of viruses, which are associated with diverse bacterial and archaeal hosts.
