  text: Recent numerical work by Bardarson, Pollmann, and Moore revealed a slow, logarithmic
    in time, growth of the entanglement entropy for initial product states in a putative
    many-body localized phase. We show that this surprising phenomenon results from
    the dephasing due to exponentially small interaction-induced corrections to the
    eigenenergies of different states. For weak interactions, we find that the entanglement
    entropy grows as ξln (Vt/), where V is the interaction strength, and ξ is the
    single-particle localization length. The saturated value of the entanglement entropy
    at long times is determined by the participation ratios of the initial state over
    the eigenstates of the subsystem. Our work shows that the logarithmic entanglement
    growth is a universal phenomenon characteristic of the many-body localized phase
    in any number of spatial dimensions, and reveals a broad hierarchy of dephasing
    time scales present in such a phase.

  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 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

  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: The colored Tverberg theorem asserts that for eve;ry d and r there exists
    t=t(d,r) such that for every set C ⊂ ℝ d of cardinality (d + 1)t, partitioned
    into t-point subsets C 1, C 2,...,C d+1 (which we think of as color classes; e.
    g., the points of C 1 are red, the points of C 2 blue, etc.), there exist r disjoint
    sets R 1, R 2,...,R r⊆C that are rainbow, meaning that {pipe}R i∩C j{pipe}≤1 for
    every i,j, and whose convex hulls all have a common point. All known proofs of
    this theorem are topological. We present a geometric version of a recent beautiful
    proof by Blagojević, Matschke, and Ziegler, avoiding a direct use of topological
    methods. The purpose of this de-topologization is to make the proof more concrete
    and intuitive, and accessible to a wider audience.

  text: We present an algorithm for computing [X, Y], i.e., all homotopy classes of
    continuous maps X → Y, where X, Y are topological spaces given as finite simplicial
    complexes, Y is (d - 1)-connected for some d ≥ 2 (for example, Y can be the d-dimensional
    sphere S d), and dim X ≤ 2d - 2. These conditions on X, Y guarantee that [X, Y]
    has a natural structure of a finitely generated Abelian group, and the algorithm
    finds generators and relations for it. We combine several tools and ideas from
    homotopy theory (such as Postnikov systems, simplicial sets, and obstruction theory)
    with algorithmic tools from effective algebraic topology (objects with effective
    homology). We hope that a further extension of the methods developed here will
    yield an algorithm for computing, in some cases of interest, the ℤ 2-index, which
    is a quantity playing a prominent role in Borsuk-Ulam style applications of topology
    in combinatorics and geometry, e.g., in topological lower bounds for the chromatic
    number of a graph. In a certain range of dimensions, deciding the embeddability
    of a simplicial complex into ℝ d also amounts to a ℤ 2-index computation. This
    is the main motivation of our work. We believe that investigating the computational
    complexity of questions in homotopy theory and similar areas presents a fascinating
    research area, and we hope that our work may help bridge the cultural gap between
    algebraic topology and theoretical computer science.

  text: 'Eigenvalues associated to graphs are a well-studied subject. In particular
    the spectra of the adjacency matrix and of the Laplacian of random graphs G(n,
    p) are known quite precisely. We consider generalizations of these matrices to
    simplicial complexes of higher dimensions and study their eigenvalues for the
    Linial-Meshulam model X k(n, p) of random k-dimensional simplicial complexes on
    n vertices. We show that for p = Ω(log n/n), the eigenvalues of both, the higher-dimensional
    adjacency matrix and the Laplacian, are a.a.s. sharply concentrated around two
    values. In a second part of the paper, we discuss a possible higherdimensional
    analogue of the Discrete Cheeger Inequality. This fundamental inequality expresses
    a close relationship between the eigenvalues of a graph and its combinatorial
    expansion properties; in particular, spectral expansion (a large eigenvalue gap)
    implies edge expansion. Recently, a higher-dimensional analogue of edge expansion
    for simplicial complexes was introduced by Gromov, and independently by Linial,
    Meshulam and Wallach and by Newman and Rabinovich. It is natural to ask whether
    there is a higher-dimensional version of Cheeger''s inequality. We show that the
    most straightforward version of a higher-dimensional Cheeger inequality fails:
    for every k &gt; 1, there is an infinite family of k-dimensional complexes that
    are spectrally expanding (there is a large eigenvalue gap for the Laplacian) but
    not combinatorially expanding.'

  text: Constitutive endocytic recycling is a crucial mechanism allowing regulation
    of the activity of proteins at the plasma membrane and for rapid changes in their
    localization, as demonstrated in plants for PIN-FORMED (PIN) proteins, the auxin
    transporters. To identify novel molecular components of endocytic recycling, mainly
    exocytosis, we designed a PIN1-green fluorescent protein fluorescence imaging-based
    forward genetic screen for Arabidopsis thaliana mutants that showed increased
    intracellular accumulation of cargos in response to the trafficking inhibitor
    brefeldin A (BFA). We identified bex5 (for BFA-visualized exocytic trafficking
    defective), a novel dominant mutant carrying a missense mutation that disrupts
    a conserved sequence motif of the small GTPase, RAS GENES FROM RAT BRAINA1b. bex5
    displays defects such as enhanced protein accumulation in abnormal BFA compartments,
    aberrant endosomes, and defective exocytosis and transcytosis. BEX5/RabA1b localizes
    to trans-Golgi network/early endosomes (TGN/EE) and acts on distinct trafficking
    processes like those regulated by GTP exchange factors on ADP-ribosylation factors
    GNOM-LIKE1 and HOPM INTERACTOR7/BFA-VISUALIZED ENDOCYTIC TRAFFICKING DEFECTIVE1,
    which regulate trafficking at the Golgi apparatus and TGN/EE, respectively. All
    together, this study identifies Arabidopsis BEX5/RabA1b as a novel regulator of
    protein trafficking from a TGN/EE compartment to the plasma membrane.

  text: The third EMBO Conference on Plant Molecular Biology, which focused on ‘Plant
    development and environmental interactions’,was held in May 2012 in Matera, Italy.
    Here, we review some of the topics and themes that emerged from the   various
    contributions; namely, steering technologies, transcriptional networks and hormonal
    regulation, small RNAs, cell and tissue polarity, environmental control and natural
    variation. We intend to provide the reader who might have missed this remarkable
    event with a glimpse of the recent progress made in this blossoming research field.
