ArticlesmiR-145 and miR-143 regulate smooth muscle cell fate and plasticity p705
Evidence for a single microRNA (miRNA) that can efficiently differentiate multipotent stem cells into a specific lineage or regulate direct reprogramming of cells into an alternative cell fate has been elusive. Two miRNAs, miR-145 and miR-143, are now shown to be co-transcribed in multipotent cardiac progenitors before becoming localized to smooth muscle cells. miR-145 was found to be necessary for myocardin-induced reprogramming of adult fibroblasts and sufficient to induce differentiation of multipotent neural crest stem cells. my booko.org,my favourite website

Architecture and secondary structure of an entire HIV-1 RNA genome p711
Single-stranded RNA viruses are responsible for the common cold, cancer, AIDS and other serious health threats. The genomes of these viruses form conserved secondary structures that have functional and regulatory roles, but most potential regulatory elements in viral RNA genomes remain uncharacterized. Here however, the structure of an entire HIV-1 genome at single nucleotide resolution is reported.

LettersA high stellar velocity dispersion for a compact massive galaxy at redshift z = 2.186 p717
The oldest and most luminous galaxies in the early Universe are surprisingly compact, having stellar masses similar to present-day elliptical galaxies but much smaller sizes. This suggests that massive galaxies have grown in size by a factor of about five over the past ten billion years, leading to the expectation that the stars in these galaxies have much higher velocities than those in present-day galaxies of the same mass. Here, the stellar velocity dispersion for a compact massive galaxy at redshift z = 2.186 is indeed found to be very high.

Observed variations of methane on Mars unexplained by known atmospheric chemistry and physics p720
Recent observations of methane on Mars suggest that methane concentrations are locally enhanced and change with the seasons. However, methane has a photochemical lifetime of several centuries, and is therefore expected to have a spatially uniform distribution on the planet. Here, using a global climate model of Mars with coupled chemistry reveals that photochemistry as currently understood cannot explain these variations in Martian methane.

The late Precambrian greening of the Earth p728
The low 13C/12C ratio in some Neoproterozoic carbonates is considered to be evidence of carbon cycle perturbations unique to the Precambrian. Here, all published oxygen and carbon isotope data for Neoproterozoic marine carbonates are compiled. The combined isotope systematics are found to be identical to those of well-understood Phanerozoic examples, suggesting an influx of photosynthetic carbon rather than perturbations to the carbon cycle — and implying an explosion of photosynthesizing communities on late Precambrian land surfaces.

Fluid and deformation regime of an advancing subduction system at Marlborough, New Zealand p733
Newly forming subduction zones on Earth can provide insights into the evolution of major fault zone geometries from shallow levels to deep in the lithosphere, and into the role of fluids in promoting rock failure by several modes. The acquisition of a transect of magnetotelluric soundings across the Marlborough strike–slip fault system of the northern South Island of New Zealand now implicates three distinct processes connecting fluid generation along the upper mantle plate interface to rock deformation in the crust as the subduction zone develops.

Advances in development reverse fertility declines p741
The increasing wealth of nations is accompanied by a fall in fertility such that in many developed and developing nations fertility rates have dropped below replacement value (less than 2.1 children per woman). Rapid population ageing, and in some cases the prospect of significant population decline, present difficult social and political problems. However, it is now shown that above a certain degree of economic development fertility begins to rise once again.

In the second of three papers on the genetics of schizophrenia, a large genome-wide association study looking at common genetic variants underlying the risk of schizophrenia implicates the major histocompatibility complex — and thus, immunity — and provides molecular genetic evidence for a substantial polygenic component to the risk of schizophrenia. The latter involves thousands of common alleles of very small effect that also contribute to the risk of bipolar disorder. welcome to booko.org

Glial cells have an essential role in the building and wiring of nervous systems. They generally migrate over long distances before they initiate differentiation, but the molecular pathways coordinating the switch from glial migration to glial differentiation are largely unknown. The study of glial cells in the Drosophila eye disc now implicates fibroblast growth factor (FGF) signalling proteins in this process. welcome to booko.org

Absolute protein concentration measurements of a considerable fraction of the proteome have, until now, only been derived from genetically altered Saccharomyces cerevisiae cells, using a technique that is not directly portable from yeast to other species. A mass-spectrometry-based method is now used to determine the absolute protein abundance for a significant fraction of the proteome of the human pathogen Leptospira interrogans.
