Agent-based modelling

Three pieces in this week's Nature discuss the use of agent-based
modelling. Joshua M. Epstein discusses how agent-based computational
modelling is playing a central part in mapping the possible spread
of H1N1, and designing policies for its mitigation. Also, J. Doyne
Farmer and Duncan Foley consider how (and why) the world's economy
needs agent-based modelling.

And in a News Feature Mark Buchanan reports on whether agent-based
computer models could prevent another financial crisis.

miR-145 and miR-143 regulate smooth muscle cell fate and plasticity
pp705-710
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.

Single-stranded RNA viruses are responsible for the common cold,

A high stellar velocity dispersion for a compact massive galaxy at
redshift z = 2.186 pp717-719
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 pp720-723
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.

Observation of strong coupling between a micromechanical resonator and
an optical cavity field pp724-727
Achieving coherent quantum control over massive mechanical resonators
via coupling to electrons or photons is a current research goal. Here,
unambiguous evidence for strong coupling of cavity photons to a
mechanical resonator is reported, paving the way for full quantum
optical control of nano- and micromechanical devices.

The late Precambrian greening of the Earth pp728-732
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 pp733-736
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.

New flutes document the earliest musical tradition in southwestern
Germany pp737-740
The existence of complex musical instruments is accepted to be an
indication of fully modern behaviour and advanced symbolic
communication. The discovery of bone and ivory flutes that are
around 35,000 years old at Hohle Fels in southwestern Germany now
demonstrates the presence of a well-established musical tradition
at the time when modern humans colonized Europe.

Advances in development reverse fertility declines pp741-743
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.

Common variants conferring risk of schizophrenia pp744-747
Here, in the first of three papers on the genetics of schizophrenia,
a genome-wide association study of single nucleotide polymorphisms
using data from several large genome-wide scans reveals significant
associations to individual loci that implicate perturbations in
immunity, brain development, memory and cognition in the
predisposition to schizophrenia.

Common polygenic variation contributes to risk of schizophrenia and
bipolar disorder pp748-752
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.

Common variants on chromosome 6p22.1 are associated with schizophrenia
pp753-757
In the third of three papers looking at the genetics of schizophrenia,
a genome-wide association study using the Molecular Genetics of
Schizophrenia case-control data set followed by a meta-analysis
further implicates the major histocompatibility complex. The study
also reveals that although common schizophrenia susceptibility alleles
can be detected, there are probably few or no single common loci with
large effects.

Switch in FGF signalling initiates glial differentiation in the
Drosophila eye pp758-761
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.

Proteome-wide cellular protein concentrations of the human pathogen
Leptospira interrogans pp762-765
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.
