Faster activity-based protein binding screens
A team from The Scripps Research Institute has developed a high
throughput technology that can screen compound libraries against
proteins whose biochemical activities are poorly characterized.
The method, which relies on fluorescent activity-based chemical
probes to identify hits, can screen libraries containing tens
of thousands of compounds, an increase of two orders of magnitude
over the capacity of existing activity-based protein binding screens.
Find out more by reading the first in-depth analysis of the
scientific and commercial potential of the work in

Generation of transgenic non-human primates with germline
transmission pp523-527
The common marmoset is an attractive candidate for transgenic
modification, and has potential as a non-human primate animal model
in biomedical research. Here, for the first time in non-human
primates, an integrated transgene is transmitted through the germ
line to the offspring, in which it continues to be expressed.

Hippocampal theta oscillations are travelling waves pp534-539
Theta oscillations are essential to temporal encoding in the
hippocampus; they clock hippocampal activity during awake behaviour
and rapid eye movement (REM) sleep. Although these 4-10-Hz
oscillations are widely believed to be synchronized throughout the
hippocampus, they are now demonstrated to form waves that travel
across the hippocampal circuit, making the organization of time in
the hippocampus similar to that on Earth[mdash]a progression of
local time zones.

Broad line emission from iron K- and L-shell transitions in the
active galaxy 1H 0707-495 pp540-542
Emission arising from a transition of an electron from the iron K
shell to the ground state (the K line) is prominent in the
reflection spectrum created by the hard X-ray continuum irradiating
the dense accreting matter around a black hole. Here the presence
of both iron K and L emission is reported in the spectrum of the
active galaxy 1H 0707-495. There is a 'reverberation lag' with a
timescale comparable to the light-crossing time of the innermost
radii around a supermassive black hole.

The changing phases of extrasolar planet CoRoT-1b pp543-545
Hot Jupiters are a class of extrasolar planet that orbit their
parent stars at very short distances and are expected to be tidally
locked, which can lead to a large temperature difference between
the dayside and the nightside. Here, the day-night contrast of the
transiting extrasolar planet HD 188733b is 'mapped' using infrared
observations; the data are consistent with the nightside hemisphere
being entirely black, with the dayside flux dominating the optical
phase curve.

Synthesizing arbitrary quantum states in a superconducting resonator

The superposition principle is a fundamental tenet of quantum

states with different numbers of photons are superposed in a
completely controlled and deterministic manner.

A picogram- and nanometre-scale photonic-crystal optomechanical
cavity pp550-555
The fact that photons of light carry momentum and can therefore
exert mechanical force is not just an academic curiosity; such
forces have already been harnessed for a variety of applications.
Here, an extreme optomechanical regime is created using a system of
simple photonic structures engineered in such a way that light and
mechanical energy are localized in a tiny volume on a silicon chip,
so that the mechanical rigidity of the resulting structure is
dominated by the optical forces.

The effect of permafrost thaw on old carbon release and net carbon
exchange from tundra pp556-559
Permafrost thaw and microbial decomposition is considered one of the
most likely positive climate feedbacks from terrestrial ecosystems
to the atmosphere in a warmer world, but the rate of carbon release
from permafrost soil remains highly uncertain. Here, net ecosystem
carbon exchange is measured in a tundra landscape undergoing
permafrost thaw to determine the influence of old carbon loss on
ecosystem carbon balance. The results reveal significant losses of
soil carbon over decadal time scales, overwhelming the increased
carbon uptake from plants.

Preserving noble gases in a convecting mantle pp560-563
An essentially undegassed mantle reservoir is thought to be required
to balance the Earth's 40Ar budget and an undegassed lower mantle
reservoir is traditionally believed to be responsible for the high
3He/4He ratios sampled at many ocean islands. On the other hand,
geophysical and geochemical observations suggest slab subduction
into the lower mantle; the subsequent process of partial melting
over the history of the Earth would leave noble gases in both upper
and lower mantle extensively outgassed. A simple solution to this
contradiction is now proposed, which lies in the recycling and
mixing of noble-gas-depleted slabs.

De novo establishment of wild-type song culture in the zebra finch
pp564-568
Although culture is often considered to be passed on through social
learning, there are species-typical constraints to cultural
diversity that could have genetic origins. By studying the
establishment of socially learned birdsong in an island colony of
naive zebra finches with a song much different from wild type, it
is now revealed that over as few as 3-4 generations the tutored
song approaches that of the wild type. Thus, species-typical song
culture can develop de novo, giving insight into language change
and evolution in humans.

Autism genome-wide copy number variation reveals ubiquitin and
neuronal genes pp569-573
Autism spectrum disorders (ASDs) are neurodevelopmental disorders
characterized by impairments in social and communication skills.
Accumulating evidence suggests a genetic component to ASDs, and
here a two-stage, genome-wide approach is used to identify
candidate genomic loci enriched in ASD cases. The majority of these
loci are found to be involved in neuronal adhesion and ubiquitin
degradation, suggesting novel susceptibility mechanisms.

Formyl peptide receptor-like proteins are a novel family of
vomeronasal chemosensors pp574-577
Two different G-protein-coupled receptor families are known to
mediate pheromonal cues in the mammalian vomeronasal organ. Here,
members of a third family of receptors, the formyl peptide
receptor-related gene family (FPRs), are shown to be expressed in
the vomeronasal epithelium, with those cells expressing FPRs
responding to ligands associated with disease and inflammation.
This raises the possibility that FPRs detect the health status of
individuals.

Bacteria hijack integrin-linked kinase to stabilize focal adhesions
and block cell detachment pp578-582
The rapid turnover and exfoliation of mucosal epithelial cells
provides an innate defence system against bacterial infection. The
Shigella virulence factor OspE, which is highly conserved among
some other enteropathogenic bacteria, is now shown to target host
intergrin-linked kinase, enhancing host cell adherence and thereby
preventing the detachment of infected cells.

A regulated auxin minimum is required for seed dispersal in
Arabidopsis pp583-586
The fruits of Arabidopsis thaliana split open (dehisce) along the
valve margins, leading to seed dispersal. A transcription factor
called INDEHISCENT (IND) is known to be important for
differentiation of valve margin cells by an unknown mechanism.
IND is now shown to be responsible for the formation of a local
auxin minimum, necessary for specification of cells in the
dehiscence zone.

Genetic analysis of radiation-induced changes in human gene
expression pp587-591
Humans are exposed to cell-damaging radiation from environmental
and medical sources, causing cells to mount complex responses that
rely on modifying gene expression. The regulators responsible for
this are now mapped through genetic linkage and association
studies, using radiation-induced changes in gene expression as
quantitative traits and providing new insight into the architecture
of gene expression regulation in response to stress.

Irreversibility of mitotic exit is the consequence of systems-level
feedback pp592-595
The eukaryotic cell cycle comprises an ordered series of events
orchestrated by cyclin-dependent kinases (Cdks), with unidirectional
cell-cycle transitions being required for its successful completion.
Proteolytic degradation of cyclins has been assumed to be
responsible for the irreversible transitions, but here it is shown
that, although forced cyclin degradation can drive mitotic exit,
the re-synthesis of cyclin means that this is not sufficient for
irreversibility. Rather, mitotic exit only become irreversible
after activation of a double-negative feedback loop.

NAADP mobilizes calcium from acidic organelles through two-pore
channels pp596-600
Ca2+ mobilization from intracellular stores represents an important
cell signalling process that is regulated, in mammalian cells, by
inositol-1,4,5-trisphosphate (InsP3), cyclic ADP ribose and
nicotinic acid adenine dinucleotide phosphate (NAADP). While the
nature of the receptors for InsP3 and cyclic ADP ribose are known,
here the lysosomal two-pore channel, TPC2, is shown to be the
molecular target of NAADP.
