text: High relatedness among interacting individuals has generally been considered
a precondition for the evolution of altruism. However, kin-selection theory also
predicts the evolution of altruism when relatedness is low, as long as the cost
of the altruistic act is minor compared to its benefit. Here, we demonstrate evidence
for a low-cost altruistic act in bacteria. We investigated Escherichia coli responding
to the attack of an obligately lytic phage by committing suicide in order to prevent
parasite transmission to nearby relatives. We found that bacterial suicide provides
large benefits to survivors at marginal costs to committers. The cost of suicide
was low because infected cells are moribund, rapidly dying upon phage infection,
such that no more opportunity for reproduction remains. As a consequence of its
marginal cost, host suicide was selectively favoured even when relatedness between
committers and survivors approached zero. Altogether, our findings demonstrate
that low-cost suicide can evolve with ease, represents an effective host-defence
strategy, and seems to be widespread among microbes. Moreover, low-cost suicide
might also occur in higher organisms as exemplified by infected social insect
workers leaving the colony to die in isolation.

text: Short-read sequencing technologies have in principle made it feasible to draw
detailed inferences about the recent history of any organism. In practice, however,
this remains challenging due to the difficulty of genome assembly in most organisms
and the lack of statistical methods powerful enough to discriminate among recent,
non-equilibrium histories. We address both the assembly and inference challenges.
We develop a bioinformatic pipeline for generating outgroup-rooted alignments
of orthologous sequence blocks from de novo low-coverage short-read data for a
small number of genomes, and show how such sequence blocks can be used to fit
explicit models of population divergence and admixture in a likelihood framework.
To illustrate our approach, we reconstruct the Pleistocene history of an oak-feeding
insect (the oak gallwasp Biorhiza pallida) which, in common with many other taxa,
was restricted during Pleistocene ice ages to a longitudinal series of southern
refugia spanning theWestern Palaearctic. Our analysis of sequence blocks sampled
from a single genome from each of three major glacial refugia reveals support
for an unexpected history dominated by recent admixture. Despite the fact that
80% of the genome is affected by admixture during the last glacial cycle, we are
able to infer the deeper divergence history of these populations. These inferences
are robust to variation in block length, mutation model, and the sampling location
of individual genomes within refugia. This combination of de novo assembly and
numerical likelihood calculation provides a powerful framework for estimating
recent population history that can be applied to any organism without the need
for prior genetic resources.

text: 'Motivated by a search for experimental probes to access the physics of fractionalized
excitations called spinons in spin liquids, we study the interaction of spinons
with lattice vibrations. We consider the case of algebraic spin liquid, when spinons
have fermionic statistics and a Dirac-like dispersion. We establish the general
procedure for deriving spinon-phonon interactions, which is based on symmetry
considerations. The procedure is illustrated for four different algebraic spin
liquids: π-flux and staggered-flux phases on a square lattice, π-flux phase on
a kagome lattice, and zero-flux phase on a honeycomb lattice. Although the low-energy
description is similar for all these phases, different underlying symmetry groups
lead to a distinct form of spinon-phonon interaction Hamiltonian. The explicit
form of the spinon-phonon interaction is used to estimate the attenuation of ultrasound
in an algebraic spin liquid. The prospects of the sound attenuation as a probe
of spinons are discussed.'

text: The mode of action of auxin is based on its non-uniform distribution within
tissues and organs. Despite the wide use of several auxin analogues in research
and agriculture, little is known about the specificity of different auxin-related
transport and signalling processes towards these compounds. Using seedlings of
Arabidopsis thaliana and suspension-cultured cells of Nicotiana tabacum (BY-2),
the physiological activity of several auxin analogues was investigated, together
with their capacity to induce auxin-dependent gene expression, to inhibit endocytosis
and to be transported across the plasma membrane. This study shows that the specificity
criteria for different auxin-related processes vary widely. Notably, the special
behaviour of some synthetic auxin analogues suggests that they might be useful
tools in investigations of the molecular mechanism of auxin action. Thus, due
to their differential stimulatory effects on DR5 expression, indole-3-propionic
(IPA) and 2,4,5-trichlorophenoxy acetic (2,4,5-T) acids can serve in studies of
TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALLING F-BOX (TIR1/AFB)-mediated auxin
signalling, and 5-fluoroindole-3-acetic acid (5-F-IAA) can help to discriminate
between transcriptional and non-transcriptional pathways of auxin signalling.
The results demonstrate that the major determinants for the auxin-like physiological
potential of a particular compound are very complex and involve its chemical and
metabolic stability, its ability to distribute in tissues in a polar manner and
its activity towards auxin signalling machinery.

text: 'We consider two core algorithmic problems for probabilistic verification:
the maximal end-component decomposition and the almost-sure reachability set computation
for Markov decision processes (MDPs). For MDPs with treewidth k, we present two
improved static algorithms for both the problems that run in time O(n·k 2.38·2k
) and O(m·logn· k), respectively, where n is the number of states and m is the
number of edges, significantly improving the previous known O(n·k·√n· k) bound
for low treewidth. We also present decremental algorithms for both problems for
MDPs with constant treewidth that run in amortized logarithmic time, which is
a huge improvement over the previously known algorithms that require amortized
linear time.'

text: Morphology is a key parameter in the design of novel nanocrystals and nanomaterials
with controlled functional properties. Here, we demonstrate the potential of foreign
metal ions to tune the morphology of colloidal semiconductor nanoparticles. We
illustrate the underlying mechanism by preparing copper selenide nanocubes in
the presence of Al ions. We further characterize the plasmonic properties of the
obtained nanocrystals and demonstrate their potential as a platform to produce
cubic nanoparticles with different composition by cation exchange. © 2013 American

text: The bottom-up assembly of nanocrystals provides access to a three-dimensional
composition control at the nanoscale not attainable by any other technology. In
particular, colloidal nanoheterostructures, with intrinsic multiphase organization,
are especially appealing building blocks for the bottom-up production of nanocomposites.
In the present work, we use PbTe-PbS as the model material system and thermoelectricity
as the paradigmatic application to investigate the potential of the bottom-up
assembly of core-shell nanoparticles to produce functional nanocomposites. With
this goal in mind, a rapid, high-yield and scalable colloidal synthetic route
to prepare grams of PbTe@PbS core-shell nanoparticles with unprecedented narrow
size distributions and exceptional composition control is detailed. PbTe@PbS nanoparticles
were used as building blocks for the bottom-up production of PbTe-PbS nanocomposites
with tuned composition. In such PbTe-PbS nanocomposites, synergistic nanocrystal
doping effects result in up to 10-fold higher electrical conductivities than in
pure PbTe and PbS nanomaterials. At the same time, the acoustic impedance mismatch
between PbTe and PbS phases and a partial phase alloying provide PbTe-PbS nanocomposites
with strongly reduced thermal conductivities. As a result, record thermoelectric
figures of merit (ZT) of ∼1.1 were obtained from undoped PbTe and PbS phases at
710 K. These high ZT values prove the potential of the proposed processes to produce
efficient functional nanomaterials with programmable properties. © 2013 American

text: Copper-based selenides are attracting increasing interest due to their outstanding
optoelectronic and thermoelectric properties. Herein a novel colloidal synthetic
route to prepare Cu2SnSe3 nanocrystals with controlled size, shape and composition
is presented. The high yield of the developed procedure allowed its up-scaling
to the production of grams of colloidal Cu2SnSe3 nanocrystals. These nanocrystals
were used as building blocks for the production of Cu2SnSe3 bulk nanostructured
materials by spark plasma sintering. The thermoelectric properties of the prepared
nanocrystalline Cu2SnSe3 pellets were characterized in the temperature range from
300 to 720 K. The obtained results show the bottom-up production of nanocrystalline
materials from solution-processed nanocrystals to be a potentially advantageous
alternative to conventional methods of production of efficient thermoelectric
materials.

text: 'A multistrategy approach to overcome the main challenges of nanoparticle-based
solution-processed Cu2ZnSnSe4 thin film solar cells is presented. We developed
an efficient ligand exchange strategy, using an antimony salt, to displace organic
ligands from the surface of Cu 2ZnSnS4 nanoparticles. An automated pulsed spray-deposition
system was used to deposit the nanoparticles into homogeneous and crack-free films
with controlled thickness. After annealing the film in a Se-rich atmosphere, carbon-free
and crystalline Cu2ZnSnSe4 absorber layers were obtained. Not only was crystallization
promoted by the complete removal of organics, but also Sb itself played a critical
role. The Sb-assisted crystal growth is associated with the formation of a Sb-based
compound at the grain boundaries, which locally reduces the melting point, thus
promoting the film diffusion-limited crystallization. '

text: The presence of organic ligands on the surface of colloidal nanoparticles
strongly limits their performance in technological applications where charge carrier
transfer/transport plays an important role. We use metal salts, matched with the
nanoparticle composition, to eliminate the surface organic ligands without introducing
extrinsic impurities in the final nanomaterial. The potential of the simple, general
and scalable processes presented here is demonstrated by characterizing the thermoelectric
properties of nanostructured Ag2Te produced by the bottom up assembly of Ag2Te
nanocrystals. A 6-fold increase of the thermoelectric figure of merit of Ag2Te
was obtained when organic ligands were displaced by AgNO3. The same procedure
can enhance the performance of nanocrystals and nanocrystal-based devices in a
broad range of applications, from photovoltaics and thermoelectrics to catalysis.

text: We report a procedure to prepare highly monodisperse copper telluride nanocubes,
nanoplates, and nanorods. The procedure is based on the reaction of a copper salt
with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide
and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption
associated with localized surface plasmon resonances. We exploit this plasmon
resonance for the design of surface-enhanced Raman scattering sensors for unconventional
optical probes. Furthermore, we also report here our preliminary analysis of the
use of CuTe nanocrystals as cytotoxic and photothermal agents.

text: The compositional versatility of I2–II–IV–VI4 tetrahedrally-coordinated compounds
allows for accommodating their functional properties to numerous technological
applications. Among them, Cu2ZnSnSe4 is an emerging photovoltaic material and
Cu2CdSnSe4 displays excellent thermoelectric properties. The third compound of
this family, Cu2HgSnSe4, remains relatively unexplored. Herein, a synthetic route
to produce Cu2HgSnSe4 nanoparticles with narrow size distribution and controlled
composition is presented. Cu2HgSnSe4 nanoparticles were subsequently used as building
blocks to produce bulk nanocrystalline materials, whose thermoelectric properties
were analyzed. A very preliminary adjustment of the material composition yielded
Seebeck coefficients up to 160 μV K−1, electrical conductivities close to 104
S m−1 and thermal conductivities down to 0.5 W m−1 K−1.

text: Until recently, to prepare nanocrystals of a new material, scientists searched
their shelves for the appropriate molecular precursors, surfactants, and solvents.
They then optimized the reaction conditions for the atoms to self-assemble into
monodisperse nanocrystals (1). This approach is being replaced by a simpler strategy,
in which preformed nanocrystals serve as templates to produce nanoparticles with
a different composition through chemical transformation. On page 964 of this issue,
Oh et al. (2) report a powerful mechanism that allows the composition of oxide
nanoparticles to be transformed in solution and at low temperatures.

text: Understanding the relative importance of heterosis and outbreeding depression
over multiple generations is a key question in evolutionary biology and is essential
for identifying appropriate genetic sources for population and ecosystem restoration.
Here we use 2455 experimental crosses between 12 population pairs of the rare
perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational
(F1, F2, F3) fitness outcomes of inter-population hybridization. We detected no
evidence of outbreeding depression, with inter-population hybrids and backcrosses
showing either similar fitness or significant heterosis for fitness components
across the three generations. Variation in heterosis among population pairs was
best explained by characteristics of the foreign source or home population, and
was greatest when the source population was large, with high genetic diversity
and low inbreeding, and the home population was small and inbred. Our results
indicate that the primary consideration for maximizing progeny fitness following
population augmentation or restoration is the use of seed from large, genetically
diverse populations.

text: 'Maternal exposure to infection occurring mid-gestation produces a three-fold
increase in the risk of schizophrenia in the offspring. The critical initiating
factor appears to be the maternal immune activation (MIA) that follows infection.
This process can be induced in rodents by exposure of pregnant dams to the viral
mimic Poly I:C, which triggers an immune response that results in structural,
functional, behavioral, and electrophysiological phenotypes in the adult offspring
that model those seen in schizophrenia. We used this model to explore the role
of synchronization in brain neural networks, a process thought to be dysfunctional
in schizophrenia and previously associated with positive, negative, and cognitive
symptoms of schizophrenia. Exposure of pregnant dams to Poly I:C on GD15 produced
an impairment in long-range neural synchrony in adult offspring between two regions
implicated in schizophrenia pathology; the hippocampus and the medial prefrontal
cortex (mPFC). This reduction in synchrony was ameliorated by acute doses of the
antipsychotic clozapine. MIA animals have previously been shown to have impaired
pre-pulse inhibition (PPI), a gold-standard measure of schizophrenia-like deficits
in animal models. Our data showed that deficits in synchrony were positively correlated
with the impairments in PPI. Subsequent analysis of LFP activity during the PPI
response also showed that reduced coupling between the mPFC and the hippocampus
following processing of the pre-pulse was associated with reduced PPI. The ability
of the MIA intervention to model neurodevelopmental aspects of schizophrenia pathology
provides a useful platform from which to investigate the ontogeny of aberrant
synchronous processes. Further, the way in which the model expresses translatable
deficits such as aberrant synchrony and reduced PPI will allow researchers to
explore novel intervention strategies targeted to these changes. '

text: Exposure of an isogenic bacterial population to a cidal antibiotic typically
fails to eliminate a small fraction of refractory cells. Historically, fractional
killing has been attributed to infrequently dividing or nondividing "persisters."
Using microfluidic cultures and time-lapse microscopy, we found that Mycobacterium
smegmatis persists by dividing in the presence of the drug isoniazid (INH). Although
persistence in these studies was characterized by stable numbers of cells, this
apparent stability was actually a dynamic state of balanced division and death.
Single cells expressed catalase-peroxidase (KatG), which activates INH, in stochastic
pulses that were negatively correlated with cell survival. These behaviors may
reflect epigenetic effects, because KatG pulsing and death were correlated between
sibling cells. Selection of lineages characterized by infrequent KatG pulsing
could allow nonresponsive adaptation during prolonged drug exposure.

text: 'Background: Reassortment between the RNA segments encoding haemagglutinin
(HA) and neuraminidase (NA), the major antigenic influenza proteins, produces
viruses with novel HA and NA subtype combinations and has preceded the emergence
of pandemic strains. It has been suggested that productive viral infection requires
a balance in the level of functional activity of HA and NA, arising from their
closely interacting roles in the viral life cycle, and that this functional balance
could be mediated by genetic changes in the HA and NA. Here, we investigate how
the selective pressure varies for H7 avian influenza HA on different NA subtype
backgrounds. Results: By extending Bayesian stochastic mutational mapping methods
to calculate the ratio of the rate of non-synonymous change to the rate of synonymous
change (d N/d S), we found the average d N/d S across the avian influenza H7 HA1
region to be significantly greater on an N2 NA subtype background than on an N1,
N3 or N7 background. Observed differences in evolutionary rates of H7 HA on different
NA subtype backgrounds could not be attributed to underlying differences between
avian host species or virus pathogenicity. Examination of d N/d S values for each
subtype on a site-by-site basis indicated that the elevated d N/d S on the N2
NA background was a result of increased selection, rather than a relaxation of
selective constraint. Conclusions: Our results are consistent with the hypothesis
that reassortment exposes influenza HA to significant changes in selective pressure
through genetic interactions with NA. Such epistatic effects might be explicitly
accounted for in future models of influenza evolution.'

text: 'All known species of extant tapirs are allopatric: 1 in southeastern Asia
and 3 in Central and South America. The fossil record for tapirs, however, is
much wider in geographical range, including Europe, Asia, and North and South
America, going back to the late Oligocene, making the present distribution a relict
of the original one. We here describe a new species of living Tapirus from the
Amazon rain forest, the 1st since T. bairdii Gill, 1865, and the 1st new Perissodactyla
in more than 100 years, from both morphological and molecular characters. It is
shorter in stature than T. terrestris (Linnaeus, 1758) and has distinctive skull
morphology, and it is basal to the clade formed by T. terrestris and T. pinchaque
(Roulin, 1829). This highlights the unrecognized biodiversity in western Amazonia,
where the biota faces increasing threats. Local peoples have long recognized our
new species, suggesting a key role for traditional knowledge in understanding
the biodiversity of the region.'

text: 'Blind signatures allow users to obtain signatures on messages hidden from
the signer; moreover, the signer cannot link the resulting message/signature pair
to the signing session. This paper presents blind signature schemes, in which
the number of interactions between the user and the signer is minimal and whose
blind signatures are short. Our schemes are defined over bilinear groups and are
proved secure in the common-reference-string model without random oracles and
under standard assumptions: CDH and the decision-linear assumption. (We also give
variants over asymmetric groups based on similar assumptions.) The blind signatures
are Waters signatures, which consist of 2 group elements. Moreover, we instantiate
partially blind signatures, where the message consists of a part hidden from the
signer and a commonly known public part, and schemes achieving perfect blindness.
We propose new variants of blind signatures, such as signer-friendly partially
blind signatures, where the public part can be chosen by the signer without prior
agreement, 3-party blind signatures, as well as blind signatures on multiple aggregated
messages provided by independent sources. We also extend Waters signatures to
non-binary alphabets by proving a new result on the underlying hash function. '
