text: The large majority of three-dimensional structures of biological macromolecules
have been determined by X-ray diffraction of crystalline samples. High-resolution
structure determination crucially depends on the homogeneity of the protein crystal.
Overall ‘rocking’ motion of molecules in the crystal is expected to influence
diffraction quality, and such motion may therefore affect the process of solving
crystal structures. Yet, so far overall molecular motion has not directly been
observed in protein crystals, and the timescale of such dynamics remains unclear.
Here we use solid-state NMR, X-ray diffraction methods and μs-long molecular dynamics
simulations to directly characterize the rigid-body motion of a protein in different
crystal forms. For ubiquitin crystals investigated in this study we determine
the range of possible correlation times of rocking motion, 0.1–100 μs. The amplitude
of rocking varies from one crystal form to another and is correlated with the
resolution obtainable in X-ray diffraction experiments.

text: We review recent advances in methodologies to study microseconds‐to‐milliseconds
exchange processes in biological molecules using magic‐angle spinning solid‐state
nuclear magnetic resonance (MAS ssNMR) spectroscopy. The particularities of MAS
ssNMR, as compared to solution‐state NMR, are elucidated using numerical simulations
and experimental data. These simulations reveal the potential of MAS NMR to provide
detailed insight into short‐lived conformations of biological molecules. Recent
studies of conformational exchange dynamics in microcrystalline ubiquitin are
discussed.

text: The nature of factors governing the tempo and mode of protein evolution is
a fundamental issue in evolutionary biology. Specifically, whether or not interactions
between different sites, or epistasis, are important in directing the course of
evolution became one of the central questions. Several recent reports have scrutinized
patterns of long-term protein evolution claiming them to be compatible only with
an epistatic fitness landscape. However, these claims have not yet been substantiated
with a formal model of protein evolution. Here, we formulate a simple covarion-like
model of protein evolution focusing on the rate at which the fitness impact of
amino acids at a site changes with time. We then apply the model to the data on
convergent and divergent protein evolution to test whether or not the incorporation
of epistatic interactions is necessary to explain the data. We find that convergent
evolution cannot be explained without the incorporation of epistasis and the rate
at which an amino acid state switches from being acceptable at a site to being
deleterious is faster than the rate of amino acid substitution. Specifically,
for proteins that have persisted in modern prokaryotic organisms since the last
universal common ancestor for one amino acid substitution approximately ten amino
acid states switch from being accessible to being deleterious, or vice versa.
Thus, molecular evolution can only be perceived in the context of rapid turnover
of which amino acids are available for evolution.

text: "In the present note we announce a proof of a strong form of Arnold diffusion
for smooth convex Hamiltonian systems. Let ${\\mathbb T}^2$ be a 2-dimensional
torus and B2 be the unit ball around the origin in ${\\mathbb R}^2$ . Fix ρ >
0. Our main result says that for a 'generic' time-periodic perturbation of an
integrable system of two degrees of freedom $H_0(p)+\\varepsilon H_1(\\theta,p,t),\\quad
\\ \\theta\\in {\\mathbb T}^2,\\ p\\in B^2,\\ t\\in {\\mathbb T}={\\mathbb R}/{\\mathbb
Z}$ , with a strictly convex H0, there exists a ρ-dense orbit (θε, pε, t)(t) in
${\\mathbb T}^2 \\times B^2 \\times {\\mathbb T}$ , namely, a ρ-neighborhood of
the orbit contains ${\\mathbb T}^2 \\times B^2 \\times {\\mathbb T}$ .\r\n\r\nOur
proof is a combination of geometric and variational methods. The fundamental elements
of the construction are the usage of crumpled normally hyperbolic invariant cylinders
from [9], flower and simple normally hyperbolic invariant manifolds from [36]
as well as their kissing property at a strong double resonance. This allows us
to build a 'connected' net of three-dimensional normally hyperbolic invariant
manifolds. To construct diffusing orbits along this net we employ a version of
the Mather variational method [41] equipped with weak KAM theory [28], proposed
by Bernard in [7]."

text: Motility is a basic feature of living microorganisms, and how it works is
often determined by environmental cues. Recent efforts have focused on developing
artificial systems that can mimic microorganisms, in particular their self-propulsion.
We report on the design and characterization of synthetic self-propelled particles
that migrate upstream, known as positive rheotaxis. This phenomenon results from
a purely physical mechanism involving the interplay between the polarity of the
particles and their alignment by a viscous torque. We show quantitative agreement
between experimental data and a simple model of an overdamped Brownian pendulum.
The model notably predicts the existence of a stagnation point in a diverging
flow. We take advantage of this property to demonstrate that our active particles
can sense and predictably organize in an imposed flow. Our colloidal system represents
an important step toward the realization of biomimetic microsystems with the ability
to sense and respond to environmental changes.

key questions in molecular evolution. We study recently emerged methacrylate reductase
function that is thought to have emerged in the last century and reported in Geobacter
sulfurreducens strain AM-1. We report the sequence and study the evolution of
the operon coding for the flavin-containing methacrylate reductase (Mrd) and tetraheme
cytochrome (Mcc) in the genome of G. sulfurreducens AM-1. Different types of signal
peptides in functionally interlinked proteins Mrd and Mcc suggest a possible complex
mechanism of biogenesis for chromoproteids of the methacrylate redox system. The
homologs of the Mrd and Mcc sequence found in δ-Proteobacteria and Deferribacteres
are also organized into an operon and their phylogenetic distribution suggested
that these two genes tend to be horizontally transferred together. Specifically,
the mrd and mcc genes from G. sulfurreducens AM-1 are not monophyletic with any
of the homologs found in other Geobacter genomes. The acquisition of methacrylate
reductase function by G. sulfurreducens AM-1 appears linked to a horizontal gene
transfer event. However, the new function of the products of mrd and mcc may have
evolved either prior or subsequent to their acquisition by G. sulfurreducens AM-1.

text: The breaking of internal tides is believed to provide a large part of the
power needed to mix the abyssal ocean and sustain the meridional overturning circulation.
Both the fraction of internal tide energy that is dissipated locally and the resulting
vertical mixing distribution are crucial for the ocean state, but remain poorly
quantified. Here we present a first worldwide estimate of mixing due to internal
tides generated at small‐scale abyssal hills. Our estimate is based on linear
wave theory, a nonlinear parameterization for wave breaking and uses quasi‐global
small‐scale abyssal hill bathymetry, stratification, and tidal data. We show that
a large fraction of abyssal‐hill generated internal tide energy is locally dissipated
over mid‐ocean ridges in the Southern Hemisphere. Significant dissipation occurs
above ridge crests, and, upon rescaling by the local stratification, follows a
monotonic exponential decay with height off the bottom, with a nonuniform decay
scale. We however show that a substantial part of the dissipation occurs over
the smoother flanks of mid‐ocean ridges, and exhibits a middepth maximum due to
the interplay of wave amplitude with stratification. We link the three‐dimensional
map of dissipation to abyssal hills characteristics, ocean stratification, and
tidal forcing, and discuss its potential implementation in time‐evolving parameterizations
for global climate models. Current tidal parameterizations only account for waves
generated at large‐scale satellite‐resolved bathymetry. Our results suggest that
the presence of small‐scale, mostly unresolved abyssal hills could significantly
enhance the spatial inhomogeneity of tidal mixing, particularly above mid‐ocean
ridges in the Southern Hemisphere.

text: The actomyosin cytoskeleton is a primary force-generating mechanism in morphogenesis,
thus a robust spatial control of cytoskeletal positioning is essential. In this
report, we demonstrate that actomyosin contractility and planar cell polarity
(PCP) interact in post-mitotic Ciona notochord cells to self-assemble and reposition
actomyosin rings, which play an essential role for cell elongation. Intriguingly,
rings always form at the cells′ anterior edge before migrating towards the center
as contractility increases, reflecting a novel dynamical property of the cortex.
Our drug and genetic manipulations uncover a tug-of-war between contractility,
which localizes cortical flows toward the equator and PCP, which tries to reposition
them. We develop a simple model of the physical forces underlying this tug-of-war,
which quantitatively reproduces our results. We thus propose a quantitative framework
for dissecting the relative contribution of contractility and PCP to the self-assembly
and repositioning of cytoskeletal structures, which should be applicable to other
morphogenetic events.

text: We give several results showing that different discrete structures typically
gain certain spanning substructures (in particular, Hamilton cycles) after a modest
random perturbation. First, we prove that adding linearly many random edges to
a dense k-uniform hypergraph ensures the (asymptotically almost sure) existence
of a perfect matching or a loose Hamilton cycle. The proof involves an interesting
application of Szemerédi's Regularity Lemma, which might be independently useful.
We next prove that digraphs with certain strong expansion properties are pancyclic,
and use this to show that adding a linear number of random edges typically makes
a dense digraph pancyclic. Finally, we prove that perturbing a certain (minimum-degree-dependent)
number of random edges in a tournament typically ensures the existence of multiple
edge-disjoint Hamilton cycles. All our results are tight.

text: Current strategies of computational crystal plasticity that focus on individual
atoms or dislocations are impractical for real-scale, large-strain problems even
with today’s computing power. Dislocation-density based approaches are a way forward
but a critical issue to address is a realistic description of the interactions
between dislocations. In this paper, a new scheme for computational dynamics of
dislocation-density functions is proposed, which takes full consideration of the
mutual elastic interactions between dislocations based on the Hirth–Lothe formulation.
Other features considered include (i) the continuity nature of the movements of
dislocation densities, (ii) forest hardening, (iii) generation according to high
spatial gradients in dislocation densities, and (iv) annihilation. Numerical implementation
by the finite-volume method, which is well suited for flow problems with high
gradients, is discussed. Numerical examples performed for a single-crystal aluminum
model show typical strength anisotropy behavior comparable to experimental observations.
Furthermore, a detailed case study on small-scale crystal plasticity successfully
captures a number of key experimental features, including power-law relation between
strength and size, low dislocation storage and jerky deformation.

text: The properties of the interface between solid and melt are key to solidification
and melting, as the interfacial free energy introduces a kinetic barrier to phase
transitions. This makes solidification happen below the melting temperature, in
out-of-equilibrium conditions at which the interfacial free energy is ill defined.
Here we draw a connection between the atomistic description of a diffuse solid-liquid
interface and its thermodynamic characterization. This framework resolves the
ambiguities in defining the solid-liquid interfacial free energy above and below
the melting temperature. In addition, we introduce a simulation protocol that
allows solid-liquid interfaces to be reversibly created and destroyed at conditions
relevant for experiments. We directly evaluate the value of the interfacial free
energy away from the melting point for a simple but realistic atomic potential,
and find a more complex temperature dependence than the constant positive slope
that has been generally assumed based on phenomenological considerations and that
has been used to interpret experiments. This methodology could be easily extended
to the study of other phase transitions, from condensation to precipitation. Our
analysis can help reconcile the textbook picture of classical nucleation theory
with the growing body of atomistic studies and mesoscale models of solidification.

text: 'Summary: Declining populations of bee pollinators are a cause of concern,
with major repercussions for biodiversity loss and food security. RNA viruses
associated with honeybees represent a potential threat to other insect pollinators,
but the extent of this threat is poorly understood. This study aims to attain
a detailed understanding of the current and ongoing risk of emerging infectious
disease (EID) transmission between managed and wild pollinator species across
a wide range of RNA viruses. Within a structured large-scale national survey across
26 independent sites, we quantify the prevalence and pathogen loads of multiple
RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee
(Bombus spp.) populations. We then construct models that compare virus prevalence
between wild and managed pollinators. Multiple RNA viruses associated with honeybees
are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees
is a significant predictor of virus prevalence in bumblebees, but we remain cautious
in speculating over the principle direction of pathogen transmission. We demonstrate
species-specific differences in prevalence, indicating significant variation in
disease susceptibility or tolerance. Pathogen loads within individual bumblebees
may be high and in the case of at least one RNA virus, prevalence is higher in
wild bumblebees than in managed honeybee populations. Our findings indicate widespread
transmission of RNA viruses between managed and wild bee pollinators, pointing
to an interconnected network of potential disease pressures within and among pollinator
species. In the context of the biodiversity crisis, our study emphasizes the importance
of targeting a wide range of pathogens and defining host associations when considering
potential drivers of population decline.'

text: To prevent epidemics, insect societies have evolved collective disease defences
that are highly effective at curing exposed individuals and limiting disease transmission
to healthy group members. Grooming is an important sanitary behaviour—either performed
towards oneself (self-grooming) or towards others (allogrooming)—to remove infectious
agents from the body surface of exposed individuals, but at the risk of disease
contraction by the groomer. We use garden ants (Lasius neglectus) and the fungal
pathogen Metarhizium as a model system to study how pathogen presence affects
self-grooming and allogrooming between exposed and healthy individuals. We develop
an epidemiological SIS model to explore how experimentally observed grooming patterns
affect disease spread within the colony, thereby providing a direct link between
the expression and direction of sanitary behaviours, and their effects on colony-level
epidemiology. We find that fungus-exposed ants increase self-grooming, while simultaneously
decreasing allogrooming. This behavioural modulation seems universally adaptive
and is predicted to contain disease spread in a great variety of host–pathogen
systems. In contrast, allogrooming directed towards pathogen-exposed individuals
might both increase and decrease disease risk. Our model reveals that the effect
of allogrooming depends on the balance between pathogen infectiousness and efficiency
of social host defences, which are likely to vary across host–pathogen systems.

text: We present a software platform for reconstructing and analyzing the growth
of a plant root system from a time-series of 3D voxelized shapes. It aligns the
shapes with each other, constructs a geometric graph representation together with
the function that records the time of growth, and organizes the branches into
a hierarchy that reflects the order of creation. The software includes the automatic
computation of structural and dynamic traits for each root in the system enabling
the quantification of growth on fine-scale. These are important advances in plant
phenotyping with applications to the study of genetic and environmental influences
on growth.

text: Bow-tie or hourglass structure is a common architectural feature found in
many biological systems. A bow-tie in a multi-layered structure occurs when intermediate
layers have much fewer components than the input and output layers. Examples include
metabolism where a handful of building blocks mediate between multiple input nutrients
and multiple output biomass components, and signaling networks where information
from numerous receptor types passes through a small set of signaling pathways
to regulate multiple output genes. Little is known, however, about how bow-tie
architectures evolve. Here, we address the evolution of bow-tie architectures
using simulations of multi-layered systems evolving to fulfill a given input-output
goal. We find that bow-ties spontaneously evolve when the information in the evolutionary
goal can be compressed. Mathematically speaking, bow-ties evolve when the rank
of the input-output matrix describing the evolutionary goal is deficient. The
maximal compression possible (the rank of the goal) determines the size of the
narrowest part of the network—that is the bow-tie. A further requirement is that
a process is active to reduce the number of links in the network, such as product-rule
mutations, otherwise a non-bow-tie solution is found in the evolutionary simulations.
This offers a mechanism to understand a common architectural principle of biological
systems, and a way to quantitate the effective rank of the goals under which they
evolved.
