text: 'Bacterial cytokinesis is commonly initiated by the Z-ring, a cytoskeletal
structure that assembles at the site of division. Its primary component is FtsZ,
a tubulin superfamily GTPase, which is recruited to the membrane by the actin-related
protein FtsA. Both proteins are required for the formation of the Z-ring, but
if and how they influence each other''s assembly dynamics is not known. Here,
we reconstituted FtsA-dependent recruitment of FtsZ polymers to supported membranes,
where both proteins self-organize into complex patterns, such as fast-moving filament
bundles and chirally rotating rings. Using fluorescence microscopy and biochemical
perturbations, we found that these large-scale rearrangements of FtsZ emerge from
its polymerization dynamics and a dual, antagonistic role of FtsA: recruitment
of FtsZ filaments to the membrane and negative regulation of FtsZ organization.
Our findings provide a model for the initial steps of bacterial cell division
and illustrate how dynamic polymers can self-organize into large-scale structures.'

text: Auxin polar transport, local maxima, and gradients have become an importantmodel
system for studying self-organization. Auxin distribution is regulated by auxin-dependent
positive feedback loops that are not well-understood at the molecular level. Previously,
we showed the involvement of the RHO of Plants (ROP) effector INTERACTOR of CONSTITUTIVELY
active ROP 1 (ICR1) in regulation of auxin transport and that ICR1 levels are
posttranscriptionally repressed at the site of maximum auxin accumulation at the
root tip. Here, we show that bimodal regulation of ICR1 levels by auxin is essential
for regulating formation of auxin local maxima and gradients. ICR1 levels increase
concomitant with increase in auxin response in lateral root primordia, cotyledon
tips, and provascular tissues. However, in the embryo hypophysis and root meristem,
when auxin exceeds critical levels, ICR1 is rapidly destabilized by an SCF(TIR1/AFB)
[SKP, Cullin, F-box (transport inhibitor response 1/auxin signaling F-box protein)]-dependent
auxin signaling mechanism. Furthermore, ectopic expression of ICR1 in the embryo
hypophysis resulted in reduction of auxin accumulation and concomitant root growth
arrest. ICR1 disappeared during root regeneration and lateral root initiation
concomitantly with the formation of a local auxin maximum in response to external
auxin treatments and transiently after gravitropic stimulation. Destabilization
of ICR1 was impaired after inhibition of auxin transport and signaling, proteasome
function, and protein synthesis. A mathematical model based on these findings
shows that an in vivo-like auxin distribution, rootward auxin flux, and shootward
reflux can be simulated without assuming preexisting tissue polarity. Our experimental
results and mathematical modeling indicate that regulation of auxin distribution
is tightly associated with auxin-dependent ICR1 levels.

text: The emergence and radiation of multicellular land plants was driven by crucial
innovations to their body plans [1]. The directional transport of the phytohormone
auxin represents a key, plant-specific mechanism for polarization and patterning
in complex seed plants [2-5]. Here, we show that already in the early diverging
land plant lineage, as exemplified by the moss Physcomitrella patens, auxin transport
by PIN transporters is operational and diversified into ER-localized and plasma
membrane-localized PIN proteins. Gain-of-function and loss-of-function analyses
revealed that PIN-dependent intercellular auxin transport in Physcomitrella mediates
crucial developmental transitions in tip-growing filaments and waves of polarization
and differentiation in leaf-like structures. Plasma membrane PIN proteins localize
in a polar manner to the tips of moss filaments, revealing an unexpected relation
between polarization mechanisms in moss tip-growing cells and multicellular tissues
of seed plants. Our results trace the origins of polarization and auxin-mediated
patterning mechanisms and highlight the crucial role of polarized auxin transport
during the evolution of multicellular land plants.

text: 'Optical transport represents a natural route towards fast communications,
and it is currently used in large scale data transfer. The progressive miniaturization
of devices for information processing calls for the microscopic tailoring of light
transport and confinement at length scales appropriate for upcoming technologies.
With this goal in mind, we present a theoretical analysis of a one-dimensional
Fabry-Perot interferometer built with two highly saturable nonlinear mirrors:
a pair of two-level systems. Our approach captures nonlinear and nonreciprocal
effects of light transport that were not reported previously. Remarkably, we show
that such an elementary device can operate as a microscopic integrated optical
rectifier.'

text: Immune systems are able to protect the body against secondary infection with
the same parasite. In insect colonies, this protection is not restricted to the
level of the individual organism, but also occurs at the societal level. Here,
we review recent evidence for and insights into the mechanisms underlying individual
and social immunisation in insects. We disentangle general immune-protective effects
from specific immune memory (priming), and examine immunisation in the context
of the lifetime of an individual and that of a colony, and of transgenerational
immunisation that benefits offspring. When appropriate, we discuss parallels with
disease defence strategies in human societies. We propose that recurrent parasitic
threats have shaped the evolution of both the individual immune systems and colony-level
social immunity in insects.

text: Oriens-lacunosum moleculare (O-LM) interneurons in the CA1 region of the hippocampus
play a key role in feedback inhibition and in the control of network activity.
However, how these cells are efficiently activated in the network remains unclear.
To address this question, I performed recordings from CA1 pyramidal neuron axons,
the presynaptic fibers that provide feedback innervation of these interneurons.
Two forms of axonal action potential (AP) modulation were identified. First, repetitive
stimulation resulted in activity-dependent AP broadening. Broadening showed fast
onset, with marked changes in AP shape following a single AP. Second, tonic depolarization
in CA1 pyramidal neuron somata induced AP broadening in the axon, and depolarization-induced
broadening summated with activity-dependent broadening. Outsideout patch recordings
from CA1 pyramidal neuron axons revealed a high density of a-dendrotoxin (α-DTX)-sensitive,
inactivating K+ channels, suggesting that K+ channel inactivation mechanistically
contributes to AP broadening. To examine the functional consequences of axonal
AP modulation for synaptic transmission, I performed paired recordings between
synaptically connected CA1 pyramidal neurons and O-LM interneurons. CA1 pyramidal
neuron-O-LM interneuron excitatory postsynaptic currents (EPSCs) showed facilitation
during both repetitive stimulation and tonic depolarization of the presynaptic
neuron. Both effects were mimicked and occluded by α-DTX, suggesting that they
were mediated by K+ channel inactivation. Therefore, axonal AP modulation can
greatly facilitate the activation of O-LM interneurons. In conclusion, modulation
of AP shape in CA1 pyramidal neuron axons substantially enhances the efficacy
of principal neuron-interneuron synapses, promoting the activation of O-LM interneurons
in recurrent inhibitory microcircuits.

text: Learning can be facilitated by previous knowledge when it is organized into
relational representations forming schemas. In this issue of Neuron, McKenzie
et al. (2014) demonstrate that the hippocampus rapidly forms interrelated, hierarchical
memory representations to support schema-based learning.

text: The protection of privacy of individual-level information in genome-wide association
study (GWAS) databases has been a major concern of researchers following the publication
of “an attack” on GWAS data by Homer et al. (2008). Traditional statistical methods
for confidentiality and privacy protection of statistical databases do not scale
well to deal with GWAS data, especially in terms of guarantees regarding protection
from linkage to external information. The more recent concept of differential
privacy, introduced by the cryptographic community, is an approach that provides
a rigorous definition of privacy with meaningful privacy guarantees in the presence
of arbitrary external information, although the guarantees may come at a serious
price in terms of data utility. Building on such notions, Uhler et al. (2013)
proposed new methods to release aggregate GWAS data without compromising an individual’s
privacy. We extend the methods developed in Uhler et al. (2013) for releasing
differentially-private χ2χ2-statistics by allowing for arbitrary number of cases
and controls, and for releasing differentially-private allelic test statistics.
We also provide a new interpretation by assuming the controls’ data are known,
which is a realistic assumption because some GWAS use publicly available data
as controls. We assess the performance of the proposed methods through a risk-utility
analysis on a real data set consisting of DNA samples collected by the Wellcome
Trust Case Control Consortium and compare the methods with the differentially-private
release mechanism proposed by Johnson and Shmatikov (2013).
