Rise and fall of political complexity in island South-East Asia and

Without high-quality data on how societies are related to each other,
it is difficult to draw quantitative conclusions about the broad
trends in history. These authors use a language-based phylogeny of
Austronesian societies to test competing models of how complex
societies rise and fall. They find that increases in complexity tend
to be stepwise, whereas large decreases are possible.

The Ndc80 complex is a key component of kinetochore that mediates

a cryo-electron microscopy reconstruction of Ndc80 bound to
microtubules. They find that Ndc80 uses a novel microtubule
recognition mode coupling tubulin binding to self-oligomerization

Gas accretion as the origin of chemical abundance gradients in
distant galaxies pp811-813
Galaxies in the early Universe might grow through the accretion of
cold, primordial, low-metallicity gas. If such gas is funnelled to
the centre of a galaxy, it will result in the central region having
an overall lower metallicity than outer regions. These authors report
such 'inverse' metallicity gradients in three rotationally supported,
star-forming galaxies at redshift [sim]3, and conclude that the
central gas has been diluted by the accretion of primordial gas.

A collision in 2009 as the origin of the debris trail of asteroid
P/2010 A2 pp814-816
The peculiar object P/2010 A2, discovered in January 2010, is in an
asteroidal orbit in the inner main asteroid belt and was given a
cometary designation because of the presence of a trail of material.
These authors report observations of P/2010 A2 by the Rosetta
spacecraft. They conclude that the trail arose from a single event,
an asteroid collision that occurred around 10 February 2009.

A recent disruption of the main-belt asteroid P/2010 A2 pp817-819
Asteroidal disruption, through high-velocity collisions or rotational
spin-up, is believed to be the primary mechanism for the production
and destruction of small asteroids. These authors report observations
of P/2010 A2 -- a previously unknown inner-belt asteroid with a
peculiar, comet-like morphology -- that reveal an approximately
120-metre-diameter nucleus with an associated tail of
millimetre-sized dust particles. They conclude that it is most
probably the evolving remnant of a recent asteroidal disruption in
February/March 2009.

Laser cooling of a diatomic molecule pp820-823
Laser cooling has not yet been extended to molecules because of their
complex internal structure. At present, the only technique for
producing ultracold molecules is to bind ultracold alkali atoms to
produce bialkali molecules. These authors experimentally demonstrate
laser cooling of the polar molecule strontium monofluoride, reaching
temperatures of a few millikelvin or less. The technique should allow
the production of molecules at microkelvin temperatures for species
that are chemically distinct from bialkalis.

An amorphous solid state of biogenic secondary organic aerosol

Secondary organic aerosol (SOA) particles can scatter radiation and

liquid, but these authors show that they can adopt an amorphous
solid state under ambient conditions. The findings challenge

Seismic evidence of negligible water carried below 400-km depth in
subducting lithosphere pp828-831
These authors test whether patterns of seismicity and the stabilities
of potentially relevant hydrous phases are consistent with a wet
lithosphere. They show that there is nearly a one-to-one correlation
between the dehydration of minerals and seismicity at depths less
than [sim]250 km, but no correlation at greater depths. They conclude
that subducting slabs must be essentially dry by 400-km depth and
thus do not provide a pathway for significant amounts of water to
enter the mantle transition zone or the lower mantle.

This very large genome-wide association study identifies hundreds of

show that the likely causal gene is often located near the most

To facilitate their proper segregation, duplicated meiotic

begins with the introduction of meiosis-specific double-strand
breaks. These authors identify a new gene in Caenorhabditis elegans,
xnd-1, that is required for crossover distribution on both the X and
the autosomal chromosomes. Preliminary data suggest that xnd-1 does
this by regulating acetylation of histone H2A on lysine 5.

ETV1 is a lineage survival factor that cooperates with KIT in
gastrointestinal stromal tumours pp849-853
Gastrointestinal stromal tumours (GIST) are believed to arise in
interstitial cells of Cajal (ICC). These authors show that the
transcription factor ETV1 is required for ICC development and
promotes the development of GIST. KIT, which is often activated by
mutations in GIST, cooperates with ETV1 in the transformation of
ICCs, in part by promoting ETV1 stabilization. Thus, a normal
developmental lineage factor is switched into a tumour-promoting
factor by a cooperating oncogene.
