Focus on Reproductive biology

At a time when the scientific, social and financial
relevance of this field is on the rise, we need dependable
information to help us decide in which direction our
research must go. By bringing together input from top
scientists, analysts and decision makers interested in
the broad field of reproductive biology, this issue of
Nature Medicine aims to become such a resource.

Nature's newsmaker of the year: Lyn Evans

Nature is pleased to honour Lyn Evan's achievement as the 2008
newsmaker of the year. For almost 15 years, he has worked as the
project manager of the Large Hadron Collider (LHC), located at CERN,
near Geneva, Switzerland and did more than any other to build the
world's newest and most powerful particle accelerator.

Some transition-metal catalysts control organic reactions so that,

Epigenetics: How to lose a tail pp885-886
Everyone carries some baggage they would like to lose. For the histone

Geometric frustration in buckled colloidal monolayers pp898-903
Geometric frustration arises when lattice structure prevents energetic
interactions between neighbouring particles to be minimized, leading to
complex phases of matter. This paper reports a simple geometrically
frustrated system composed of closely packed colloidal spheres confined
between parallel walls. Because the diameter of the spheres is tunable,
the system provides a unique means to directly visualize the dynamics
of frustration, thermal excitations and defects.

Neural palmitoyl-proteomics reveals dynamic synaptic palmitoylation
pp904-909
A proteomics study unveils a large collection of proteins that get
reversibly palmitoylated in response to neuronal activity - the neuronal
palmitoyl-proteome. In particular, this study focuses on the discovery
of a brain-specific isoform of the small GTPase Cdc42, whose unexpected
palmitoylation specifically affects dendritic spine morphogenesis in
response to neuronal activity. These findings identify palmitoylation
as a key modifiable signal on many synapse-enriched proteins that
contribute to activity-driven changes in synapse morphology and function.

SUMOylation regulates Rad18-mediated template switch pp915-920
When damaged DNA is replicated, gaps can be left behind in the
replicated DNA. Two processes, recombinational repair or
post-replication repair (PRR), were thought to act independently in
gap filling. This study defines how the error-free branch of PRR
is involved in lesion bypass and finds that when the replicative
clamp PCNA is SUMO modified, Rad18 and Rad5 are able to promote
polyubiquitination of PCNA.

A gravitationally lensed water maser in the early Universe
pp927-929
This paper reports the discovery of a water maser at redshift 2.64 in
the dust- and gas-rich gravitationally lensed type-1 quasar
MG J0414+0534. Using the locally determined luminosity function, the
probability of finding a maser this luminous associated with any single
active galaxy is 10-6, leading to the conclusion that the volume
densities and luminosities of masers are higher at that epoch.

These new catalysts bear a stereogenic metal centre and carry only

non-racemic by a stereoselective ligand exchange process involving an
enantiomerically pure aryloxide, a class of ligands rarely used in
asymmetric catalysis.

How supercontinents and superoceans affect seafloor roughness
pp938-941
This study presents a global analysis of seafloor roughness derived
from marine gravity data and finds that residual roughness anomalies
remain over large swaths of ocean floor. The Atlantic ocean floor that
formed over mantle previously overlain by the Pangaea supercontinent
displays anomalously low roughness, and attribute this observation to
a sub-Pangaean supercontinental mantle temperature anomaly leading to
slightly thicker than normal Atlantic crust. In contrast, ocean crust
formed above Pacific superswells is not associated with basement
roughness anomalies.

Low conservation of gene content in the Drosophila Y chromosome pp949-951
In Drosophila more than 95% of the genes have remained on the same

the mammalian Y, gene gains play an important role in the evolution of
the Drosophila Y chromosome.

Experience with moving visual stimuli drives the early development of
cortical direction selectivity pp952-956
Neural circuits in the visual cortex are immature at birth, and require
exposure to visual stimuli to form the connections and selectivity of
the mature visual system. It has been unclear how stimulus-driven neural
activity guides the emergence of properties such as direction
selectivity. This paper tracks this process with a combination of
intrinsic and two-photon calcium imaging in visually naive ferrets.
After exposing the animals to stimuli moving along one single axis of
motion, it is found that selectivity for those directions emerges
rapidly as well as the local organization of direction preference
between neighbouring cells.

Contact inhibition of locomotion in vivo controls neural crest
directional migration pp957-961
This paper studies a phenomenon called contact inhibition of locomotion,
whereby fibroblast cells grown in cell culture retract their protrusions
and change their direction on contact. It is shown that this occurs in
vivo, and the molecular basis is revealed. Neural crest cells, highly
migratory cells of embryonic origin, exhibit contact inhibition of
locomotion both in vivo and in vitro, which accounts for their
directional migration. However, when a neural crest cell meets another
cell type, it fails to display contact inhibition of locomotion,
allowing it to invade the tissue.

Generation of cell polarity in plants links endocytosis, auxin
distribution and cell fate decisions pp962-966
The polar transport of the plant hormone auxin is dependent on the
localization of its efflux carriers called PINs, but the mechanism
mediating polarity of PIN proteins within cells remains unclear. This
study suggests a two-step mechanism generating PIN polarity. PINs are
first targeted to the plasma membrane in a non-polar manner, and
polarity is established in subsequent step involving internalization
and recycling. Interference with endocytosis results in the loss of PIN
polarity leading to a perturbation in auxin gradients.

Suppression of Myc oncogenic activity by ribosomal protein
haploinsufficiency pp971-975
This study shows that Myc-driven tumourigenesis is dependent on its
ability to increase protein synthesis, as haploinsufficiency in
ribosomal proteins decreases Myc-induced tumour formation. However,
tumours caused by the loss of p53, were not affected. Myc stimulates
cap-dependent protein translation at the expense of IRES-dependent
translation, leading to the synthesis of a different set of proteins,
and this effect is reversed by ribosomal protein haploinsufficiency.

was possible to reverse these effects, demonstrating that therapeutic
treatment to downregulate a microRNA can be effective in vivo.

The classical pentraxins, serum amyloid P component (SAP) and C-reactive

receptor binding sites for SAP and IgG overlap, resulting in competition
of IgG binding to Fc[gamma]R as well as inhibition of immune
complex-mediated phagocytosis by soluble pentraxins.

Endonucleolytic RNA cleavage by a eukaryotic exosome pp993-996
The exosome is a multisubunit exonuclease complex that degrades many
types of RNAs, in many different contexts, in a 3' to 5' manner. The
catalytic component of the exosome is the Dis3 subunit. Dis3 contains
a PIN domain, which is sometimes associated with nuclease activity.
This work shows that the Dis3 PIN domain also possesses endonuclease
activity (that is, it can cleave RNA internally, rather than from an end).
Mutations in either this domain or in the exonuclease domain exhibit a
growth phenotype, suggesting that both activities are physiologically
important.

Nuclear receptor corepressor and histone deacetylase 3 govern circadian

of a functional Ncor-HdaC3 complex in vivo changes the oscillatory

regulation of metabolism is critical for normal energy balance.
