text: De novo protein synthesis is required for synapse modifications underlying
stable memory encoding. Yet neurons are highly compartmentalized cells and how
protein synthesis can be regulated at the synapse level is unknown. Here, we characterize
neuronal signaling complexes formed by the postsynaptic scaffold GIT1, the mechanistic
target of rapamycin (mTOR) kinase, and Raptor that couple synaptic stimuli to
mTOR-dependent protein synthesis; and identify NMDA receptors containing GluN3A
subunits as key negative regulators of GIT1 binding to mTOR. Disruption of GIT1/mTOR
complexes by enhancing GluN3A expression or silencing GIT1 inhibits synaptic mTOR
activation and restricts the mTOR-dependent translation of specific activity-regulated
mRNAs. Conversely, GluN3A removal enables complex formation, potentiates mTOR-dependent
protein synthesis, and facilitates the consolidation of associative and spatial
memories in mice. The memory enhancement becomes evident with light or spaced
training, can be achieved by selectively deleting GluN3A from excitatory neurons
during adulthood, and does not compromise other aspects of cognition such as memory
flexibility or extinction. Our findings provide mechanistic insight into synaptic
translational control and reveal a potentially selective target for cognitive
enhancement.

text: 'Nitrogen is an essential macronutrient determining plant growth, development
and affecting agricultural productivity. Root, as a hub that perceives and integrates
local and systemic signals on the plant’s external and endogenous nitrogen resources,
communicates with other plant organs to consolidate their physiology and development
in accordance with actual nitrogen balance. Over the last years, numerous studies
demonstrated that these comprehensive developmental adaptations rely on the interaction
between pathways controlling nitrogen homeostasis and hormonal networks acting
globally in the plant body. However, molecular insights into how the information
about the nitrogen status is translated through hormonal pathways into specific
developmental output are lacking. In my work, I addressed so far poorly understood
mechanisms underlying root-to-shoot communication that lead to a rapid re-adjustment
of shoot growth and development after nitrate provision. Applying a combination
of molecular, cell, and developmental biology approaches, genetics and grafting
experiments as well as hormonal analytics, I identified and characterized an unknown
molecular framework orchestrating shoot development with a root nitrate sensory
system. '

text: Bacteria-host interactions represent a continuous trade-off between benefit
and risk. Thus, the host immune response is faced with a non-trivial problem –
accommodate beneficial commensals and remove harmful pathogens. This is especially
difficult as molecular patterns, such as lipopolysaccharide or specific surface
organelles such as pili, are conserved in both, commensal and pathogenic bacteria.
Type 1 pili, tightly regulated by phase variation, are considered an important
virulence factor of pathogenic bacteria as they facilitate invasion into host
cells. While invasion represents a de facto passive mechanism for pathogens to
escape the host immune response, we demonstrate a fundamental role of type 1 pili
as active modulators of the innate and adaptive immune response.

text: A high-resolution structure of trimeric cyanobacterial Photosystem I (PSI)
from Thermosynechococcus elongatus was reported as the first atomic model of PSI
almost 20 years ago. However, the monomeric PSI structure has not yet been reported
despite long-standing interest in its structure and extensive spectroscopic characterization
of the loss of red chlorophylls upon monomerization. Here, we describe the structure
of monomeric PSI from Thermosynechococcus elongatus BP-1. Comparison with the
trimer structure gave detailed insights into monomerization-induced changes in
both the central trimerization domain and the peripheral regions of the complex.
Monomerization-induced loss of red chlorophylls is assigned to a cluster of chlorophylls
adjacent to PsaX. Based on our findings, we propose a role of PsaX in the stabilization
of red chlorophylls and that lipids of the surrounding membrane present a major
source of thermal energy for uphill excitation energy transfer from red chlorophylls
to P700.

text: A key attribute of persistent or recurring bacterial infections is the ability
of the pathogen to evade the host’s immune response. Many Enterobacteriaceae express
type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and
establish persistent infections. However, the molecular mechanisms and strategies
by which bacteria actively circumvent the immune response of the host remain poorly
understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide
detection, on dendritic cells as a previously undescribed binding partner of FimH,
the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH
amino acids involved in CD14 binding are highly conserved across pathogenic and
non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced
dendritic cell migration and blunted expression of co-stimulatory molecules, both
rate-limiting factors of T cell activation. While defining an active molecular
mechanism of immune evasion by pathogens, the interaction between FimH and CD14
represents a potential target to interfere with persistent and recurrent infections,
such as urinary tract infections or Crohn’s disease.

text: To survive elevated temperatures, ectotherms adjust the fluidity of membranes
by fine-tuning lipid desaturation levels in a process previously described to
be cell autonomous. We have discovered that, in Caenorhabditis elegans, neuronal
heat shock factor 1 (HSF-1), the conserved master regulator of the heat shock
response (HSR), causes extensive fat remodeling in peripheral tissues. These changes
include a decrease in fat desaturase and acid lipase expression in the intestine
and a global shift in the saturation levels of plasma membrane’s phospholipids.
The observed remodeling of plasma membrane is in line with ectothermic adaptive
responses and gives worms a cumulative advantage to warm temperatures. We have
determined that at least 6 TAX-2/TAX-4 cyclic guanosine monophosphate (cGMP) gated
channel expressing sensory neurons, and transforming growth factor ß (TGF-β)/bone
morphogenetic protein (BMP) are required for signaling across tissues to modulate
fat desaturation. We also find neuronal hsf-1 is not only sufficient but also
partially necessary to control the fat remodeling response and for survival at
warm temperatures. This is the first study to show that a thermostat-based mechanism
can cell nonautonomously coordinate membrane saturation and composition across
tissues in a multicellular animal.

text: Molecular chaperones are central to cellular protein homeostasis. Dynamic
disorder is a key feature of the complexes of molecular chaperones and their client
proteins, and it facilitates the client release towards a folded state or the
handover to downstream components. The dynamic nature also implies that a given
chaperone can interact with many different client proteins, based on physico-chemical
sequence properties rather than on structural complementarity of their (folded)
3D structure. Yet, the balance between this promiscuity and some degree of client
specificity is poorly understood. Here, we review recent atomic-level descriptions
of chaperones with client proteins, including chaperones in complex with intrinsically
disordered proteins, with membrane-protein precursors, or partially folded client
proteins. We focus hereby on chaperone-client interactions that are independent
of ATP. The picture emerging from these studies highlights the importance of dynamics
in these complexes, whereby several interaction types, not only hydrophobic ones,
contribute to the complex formation. We discuss these features of chaperone-client
complexes and possible factors that may contribute to this balance of promiscuity
and specificity.

text: Off-chain protocols (channels) are a promising solution to the scalability
and privacy challenges of blockchain payments. Current proposals, however, require
synchrony assumptions to preserve the safety of a channel, leaking to an adversary
the exact amount of time needed to control the network for a successful attack.
In this paper, we introduce Brick, the first payment channel that remains secure
under network asynchrony and concurrently provides correct incentives. The core
idea is to incorporate the conflict resolution process within the channel by introducing
a rational committee of external parties, called wardens. Hence, if a party wants
to close a channel unilaterally, it can only get the committee’s approval for
the last valid state. Additionally, Brick provides sub-second latency because
it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast
to announce updates and close the channel, a light-weight abstraction that is
powerful enough to preserve safety and liveness to any rational parties. We formally
define and prove for Brick the properties a payment channel construction should
fulfill. We also design incentives for Brick such that honest and rational behavior
aligns. Finally, we provide a reference implementation of the smart contracts
in Solidity.

text: Since the inception of Bitcoin, a plethora of distributed ledgers differing
in design and purpose has been created. While by design, blockchains provide no
means to securely communicate with external systems, numerous attempts towards
trustless cross-chain communication have been proposed over the years. Today,
cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges,
scalability efforts via sharding, extension of existing systems through sidechains,
and bootstrapping of new blockchains. Unfortunately, existing proposals are designed
ad-hoc for specific use-cases, making it hard to gain confidence in their correctness
and composability. We provide the first systematic exposition of cross-chain communication
protocols. We formalize the underlying research problem and show that CCC is impossible
without a trusted third party, contrary to common beliefs in the blockchain community.
With this result in mind, we develop a framework to design new and evaluate existing
CCC protocols, focusing on the inherent trust assumptions thereof, and derive
a classification covering the field of cross-chain communication to date. We conclude
by discussing open challenges for CCC research and the implications of interoperability
on the security and privacy of blockchains.

text: Composite materials offer numerous advantages in a wide range of applications,
including thermoelectrics. Here, semiconductor–metal composites are produced by
just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
and at room temperature with a metallic Cu powder. The obtained blend is annealed
in a reducing atmosphere and afterward consolidated into dense polycrystalline
pellets through spark plasma sintering (SPS). We observe that, during the annealing
process, the presence of metallic copper activates a partial reduction of the
PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
lead during the SPS process habilitates the liquid-phase sintering of the composite.
Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
that the presence of metallic lead decisively contributes to a strong increase
of the charge carrier concentration through spillover of charge carriers enabled
by the low work function of lead. The increase in charge carrier concentration
translates into much higher electrical conductivities and moderately lower Seebeck
coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
the presence of multiple phases in the final composite results in a notable decrease
in the lattice thermal conductivity. Overall, the introduction of metallic copper
in the initial blend results in a significant improvement of the thermoelectric
performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
= 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.

text: In the nuclear pore complex, intrinsically disordered proteins (FG Nups),
along with their interactions with more globular proteins called nuclear transport
receptors (NTRs), are vital to the selectivity of transport into and out of the
cell nucleus. Although such interactions can be modeled at different levels of
coarse graining, in vitro experimental data have been quantitatively described
by minimal models that describe FG Nups as cohesive homogeneous polymers and NTRs
as uniformly cohesive spheres, in which the heterogeneous effects have been smeared
out. By definition, these minimal models do not account for the explicit heterogeneities
in FG Nup sequences, essentially a string of cohesive and noncohesive polymer
units, and at the NTR surface. Here, we develop computational and analytical models
that do take into account such heterogeneity in a minimal fashion and compare
them with experimental data on single-molecule interactions between FG Nups and
NTRs. Overall, we find that the heterogeneous nature of FG Nups and NTRs does
play a role in determining equilibrium binding properties but is of much greater
significance when it comes to unbinding and binding kinetics. Using our models,
we predict how binding equilibria and kinetics depend on the distribution of cohesive
blocks in the FG Nup sequences and of the binding pockets at the NTR surface,
with multivalency playing a key role. Finally, we observe that single-molecule
binding kinetics has a rather minor influence on the diffusion of NTRs in polymer
melts consisting of FG-Nup-like sequences.

text: We study the effects of osmotic shocks on lipid vesicles via coarse-grained
molecular dynamics simulations by explicitly considering the solute in the system.
We find that depending on their nature (hypo- or hypertonic) such shocks can lead
to bursting events or engulfing of external material into inner compartments,
among other morphology transformations. We characterize the dynamics of these
processes and observe a separation of time scales between the osmotic shock absorption
and the shape relaxation. Our work consequently provides an insight into the dynamics
of compartmentalization in vesicular systems as a result of osmotic shocks, which
can be of interest in the context of early proto-cell development and proto-cell
compartmentalisation.

text: 'The cell membrane is an inhomogeneous system composed of phospholipids, sterols,
carbohydrates, and proteins that can be directly attached to underlying cytoskeleton.
The protein linkers between the membrane and the cytoskeleton are believed to
have a profound effect on the mechanical properties of the cell membrane and its
ability to reshape. Here, we investigate the role of membrane-cortex linkers on
the extrusion of membrane tubes using computer simulations and experiments. In
simulations, we find that the force for tube extrusion has a nonlinear dependence
on the density of membrane-cortex attachments: at a range of low and intermediate
linker densities, the force is not significantly influenced by the presence of
the membrane-cortex attachments and resembles that of the bare membrane. For large
concentrations of linkers, however, the force substantially increases compared
with the bare membrane. In both cases, the linkers provided membrane tubes with
increased stability against coalescence. We then pulled tubes from HEK cells using
optical tweezers for varying expression levels of the membrane-cortex attachment
protein Ezrin. In line with simulations, we observed that overexpression of Ezrin
led to an increased extrusion force, while Ezrin depletion had a negligible effect
on the force. Our results shed light on the importance of local protein rearrangements
for membrane reshaping at nanoscopic scales.'

text: Erythropoietin enhances oxygen delivery and reduces hypoxia-induced cell death,
but its pro-thrombotic activity is problematic for use of erythropoietin in treating
hypoxia. We constructed a fusion protein that stimulates red blood cell production
and neuroprotection without triggering platelet production, a marker for thrombosis.
The protein consists of an anti-glycophorin A nanobody and an erythropoietin mutant
(L108A). The mutation reduces activation of erythropoietin receptor homodimers
that induce erythropoiesis and thrombosis, but maintains the tissue-protective
signaling. The binding of the nanobody element to glycophorin A rescues homodimeric
erythropoietin receptor activation on red blood cell precursors. In a cell proliferation
assay, the fusion protein is active at 10−14 M, allowing an estimate of the number
of receptor–ligand complexes needed for signaling. This fusion protein stimulates
erythroid cell proliferation in vitro and in mice, and shows neuroprotective activity
in vitro. Our erythropoietin fusion protein presents a novel molecule for treating
hypoxia.

text: The early development of many organisms involves the folding of cell monolayers,
but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic
causes and effects of local curvature remain unclear. Here we study epithelial
cell monolayers on corrugated hydrogels engineered into wavy patterns, examining
how concave and convex curvatures affect cellular and nuclear shape. We find that
substrate curvature affects monolayer thickness, which is larger in valleys than
crests. We show that this feature generically arises in a vertex model, leading
to the hypothesis that cells may sense curvature by modifying the thickness of
the tissue. We find that local curvature also affects nuclear morphology and positioning,
which we explain by extending the vertex model to take into account membrane–nucleus
interactions, encoding thickness modulation in changes to nuclear deformation
and position. We propose that curvature governs the spatial distribution of yes-associated
proteins via nuclear shape and density changes. We show that curvature also induces
significant variations in lamins, chromatin condensation and cell proliferation
rate in folded epithelial tissues. Together, this work identifies active cell
mechanics and nuclear mechanoadaptation as the key players of the mechanistic
regulation of epithelia to substrate curvature.

text: How information is created, shared and consumed has changed rapidly in recent
decades, in part thanks to new social platforms and technologies on the web. With
ever-larger amounts of unstructured and limited labels, organizing and reconciling
information from different sources and modalities is a central challenge in machine
learning. This cutting-edge tutorial aims to introduce the multimodal entailment
task, which can be useful for detecting semantic alignments when a single modality
alone does not suffice for a whole content understanding. Starting with a brief
overview of natural language processing, computer vision, structured data and
neural graph learning, we lay the foundations for the multimodal sections to follow.
We then discuss recent multimodal learning literature covering visual, audio and
language streams, and explore case studies focusing on tasks which require fine-grained
understanding of visual and linguistic semantics question answering, veracity
and hatred classification. Finally, we introduce a new dataset for recognizing
multimodal entailment, exploring it in a hands-on collaborative section. Overall,
this tutorial gives an overview of multimodal learning, introduces a multimodal
entailment dataset, and encourages future research in the topic.

text: Theoretical and experimental studies of the interaction between spins and
temperature are vital for the development of spin caloritronics, as they dictate
the design of future devices. In this work, we propose a two-terminal cold-atom
simulator to study that interaction. The proposed quantum simulator consists of
strongly interacting atoms that occupy two temperature reservoirs connected by
a one-dimensional link. First, we argue that the dynamics in the link can be described
using an inhomogeneous Heisenberg spin chain whose couplings are defined by the
local temperature. Second, we show the existence of a spin current in a system
with a temperature difference by studying the dynamics that follows the spin-flip
of an atom in the link. A temperature gradient accelerates the impurity in one
direction more than in the other, leading to an overall spin current similar to
the spin Seebeck effect.

text: Branching morphogenesis governs the formation of many organs such as lung,
kidney, and the neurovascular system. Many studies have explored system-specific
molecular and cellular regulatory mechanisms, as well as self-organizing rules
underlying branching morphogenesis. However, in addition to local cues, branched
tissue growth can also be influenced by global guidance. Here, we develop a theoretical
framework for a stochastic self-organized branching process in the presence of
external cues. Combining analytical theory with numerical simulations, we predict
differential signatures of global vs. local regulatory mechanisms on the branching
pattern, such as angle distributions, domain size, and space-filling efficiency.
We find that branch alignment follows a generic scaling law determined by the
strength of global guidance, while local interactions influence the tissue density
but not its overall territory. Finally, using zebrafish innervation as a model
system, we test these key features of the model experimentally. Our work thus
provides quantitative predictions to disentangle the role of different types of
cues in shaping branched structures across scales.
