Tyrosine dephosphorylation of H2AX modulates apoptosis and survival
decisions pp591-596
The protein tyrosine phosphatase EYA is shown to be recruited to DNA
double-strand breaks after genotoxic stress and to remove a tyrosine
phosphorylation modification on histone H2AX. The tyrosine
phosphorylation state of H2AX helps to determine whether DNA repair
or pro-apoptotic factors are recruited to chromatin, with tyrosine
dephosphorylation by EYA promoting repair rather than apoptosis.

From April 2009, the Nature Clinical Practice journals will
be renamed Nature Reviews.

Nature Clinical Practice Rheumatology has been completely
redesigned and is now called Nature Reviews Rheumatology to
bring all the qualities of this top-ranked* life science

Early assembly of the most massive galaxies pp603-606
Galaxies are thought to grow gradually from the early Universe by
star formation and mergers, according to huge recent galaxy formation
simulations. But here Collins et al. report that Brightest Cluster
Galaxies, the most luminous stellar objects, have not increased much
in mass over the past 9 billion years or so: they were already almost
fully grown 4 or 5 billion years after the Big Bang.

An anomalous positron abundance in cosmic rays with energies 1.5-100
GeV pp607-609
Cosmic ray positrons are known to be produced by interactions in the
interstellar medium, but they might also originate in primary sources,
such as pulsars, micro-quasars or through dark matter annihilation.
Adriani et al. report that the positron fraction increases sharply
over much of the energy range 1.5-100 GeV, which appears to be
completely inconsistent with secondary sources--they therefore
conclude that a primary source is necessary.

The axis of a spinning electron tends to remain fixed in direction:
in contrast, an electron moving in a semiconductor sees a lattice of
charged atoms flying past, causing its spin direction to fluctuate.
Koralek and colleagues demonstrate that an electric field applied to
the semiconductor can balance this spin-destabilizing effect; the
collective spin of the entire gas of electrons is conserved, a
property well-suited for 'spintronics' applications.

Solubility trapping in formation water as dominant CO2 sink in natural
gas fields pp614-618
Injecting industrial CO2 into deep geological strata could be a safe
and economical means of storing it, either dissolved in solution or
absorbed by carbonate minerals. Chris Ballentine and colleagues used
noble gas and isotope tracers to identify what happens to CO2 in gas
fields in North America, China and Europe that provide a natural model
of geological storage of anthropogenic CO2 over millennia. They find
that dissolution in water is the main mechanism.

Petrological evidence for secular cooling in mantle plumes pp619-622
Oceanic island basalts have much lower eruption rates than lavas from
large igneous provinces, but a quantitative petrological comparison
of lava sources has not been made. Claude Herzberg and Esteban Gazel
have examined the composition of Galapagos-related lavas, and conclude
that the mantle plumes that generated large igneous provinces in the
Permian to Palaeocene periods were hotter and melted more extensively
than the plumes that produced modern oceanic islands.

Initial community evenness favours functionality under selective
stress pp623-626
Ecosystem functioning is well known to be affected by species richness
(the number of species), but species evenness (relative abundance of
species) has been much less studied. Boon et al. investigated the
effect of species unevenness in 1,260 denitrifying bacterial microcosms
and found that initial evenness strongly improved ecosystem functioning,
especially under stress.

A micro-architecture for binocular disparity and ocular dominance in
visual cortex pp627-631
Using two-photon calcium imaging these authors map the response of

find that the responses to ocular dominance and binocular disparity
exist on defined axes within the brain that are independent and
orthogonal to each other.

Decoding reveals the contents of visual working memory in early visual

This study shows that early visual areas can retain specific

no physical stimulus present. Using functional magnetic resonance

early visual area activity with a high degree of accuracy.

Adaptation of HIV-1 to human leukocyte antigen class I pp641-645
This paper traces the adaptation of HIV to HLA alleles in 2,500

the prevalence of escape mutations within well characterized
epitopes and the prevalence of the respective HLA alleles, thereby
providing evidence that the virus is indeed adapting to effective
immune responses.

FGF signalling during embryo development regulates cilia length in
diverse epithelia pp651-654
These authors show that fibroblast growth factor (FGF) signalling
regulates cilia length and function in diverse epithelia during
zebrafish and Xenopus development. They propose that some
developmental defects and diseases ascribed to FGF signalling are
due in part to loss of cilia function.

Clustering of InsP3 receptors by InsP3 retunes their regulation by
InsP3 and Ca2+ pp655-659
This papers shows that inositol-1,4,5-trisphosphate (InsP3) receptors
aggregate in responses to InsP3, resulting in a lower probability of
channel opening, and that increases in intracellular Ca2+ can
effectively relieve this inhibition and enhance the coupling between
receptors in a cluster. This mechanism probably serves to enhance the
sensitivity to changes in intracellular Ca2+.

highlights the complexity of post-translational protein
modifications. Leading experts analyze atypical
ubiquitin-chain formation, ATGylation, polyglutamylation,
neddylation, and Urmylation, and update our knowledge on
poly(ADP-ribosyl)ation and O-GlcNAcylation. A complex but
important topic to understand!
