text: Epigenetic reprogramming is required for proper regulation of gene expression
in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for
seed viability, pollen function, and successful reproduction. The DEMETER (DME)
DNA glycosylase initiates localized DNA demethylation in vegetative and central
cells, so-called companion cells that are adjacent to sperm and egg gametes, respectively.
In rice, the central cell genome displays local DNA hypomethylation, suggesting
that active DNA demethylation also occurs in rice; however, the enzyme responsible
for this process is unknown. One candidate is the rice REPRESSOR OF SILENCING
1a (ROS1a) gene, which is related to DME and is essential for rice seed viability
and pollen function. Here, we report genome-wide analyses of DNA methylation in
wild-type and ros1a mutant sperm and vegetative cells. We find that the rice vegetative
cell genome is locally hypomethylated compared with sperm by a process that requires
ROS1a activity. We show that many ROS1a target sequences in the vegetative cell
are hypomethylated in the rice central cell, suggesting that ROS1a also demethylates
the central cell genome. Similar to Arabidopsis, we show that sperm non-CG methylation
is indirectly promoted by DNA demethylation in the vegetative cell. These results
reveal that DNA glycosylase-mediated DNA demethylation processes are conserved
in Arabidopsis and rice, plant species that diverged 150 million years ago. Finally,
although global non-CG methylation levels of sperm and egg differ, the maternal
and paternal embryo genomes show similar non-CG methylation levels, suggesting
that rice gamete genomes undergo dynamic DNA methylation reprogramming after cell
fusion.

text: A central goal of computational physics and chemistry is to predict material
properties by using first-principles methods based on the fundamental laws of
quantum mechanics. However, the high computational costs of these methods typically
prevent rigorous predictions of macroscopic quantities at finite temperatures,
such as heat capacity, density, and chemical potential. Here, we enable such predictions
by marrying advanced free-energy methods with data-driven machine-learning interatomic
potentials. We show that, for the ubiquitous and technologically essential system
of water, a first-principles thermodynamic description not only leads to excellent
agreement with experiments, but also reveals the crucial role of nuclear quantum
fluctuations in modulating the thermodynamic stabilities of different phases of
water.

text: Modern molecular genetic datasets, primarily collected to study the biology
of human health and disease, can be used to directly measure the action of natural
selection and reveal important features of contemporary human evolution. Here
we leverage the UK Biobank data to test for the presence of linear and nonlinear
natural selection in a contemporary population of the United Kingdom. We obtain
phenotypic and genetic evidence consistent with the action of linear/directional
selection. Phenotypic evidence suggests that stabilizing selection, which acts
to reduce variance in the population without necessarily modifying the population
mean, is widespread and relatively weak in comparison with estimates from other
species.

text: The optic tectum (TeO), or superior colliculus, is a multisensory midbrain
center that organizes spatially orienting responses to relevant stimuli. To define
the stimulus with the highest priority at each moment, a network of reciprocal
connections between the TeO and the isthmi promotes competition between concurrent
tectal inputs. In the avian midbrain, the neurons mediating enhancement and suppression
of tectal inputs are located in separate isthmic nuclei, facilitating the analysis
of the neural processes that mediate competition. A specific subset of radial
neurons in the intermediate tectal layers relay retinal inputs to the isthmi,
but at present it is unclear whether separate neurons innervate individual nuclei
or a single neural type sends a common input to several of them. In this study,
we used in vitro neural tracing and cell-filling experiments in chickens to show
that single neurons innervate, via axon collaterals, the three nuclei that comprise
the isthmotectal network. This demonstrates that the input signals representing
the strength of the incoming stimuli are simultaneously relayed to the mechanisms
promoting both enhancement and suppression of the input signals. By performing
in vivo recordings in anesthetized chicks, we also show that this common input
generates synchrony between both antagonistic mechanisms, demonstrating that activity
enhancement and suppression are closely coordinated. From a computational point
of view, these results suggest that these tectal neurons constitute integrative
nodes that combine inputs from different sources to drive in parallel several
concurrent neural processes, each performing complementary functions within the
network through different firing patterns and connectivity.

text: Neuropeptides are ubiquitous modulators of behavior and physiology. They are
packaged in specialized secretory organelles called dense core vesicles (DCVs)
that are released upon neural stimulation. Unlike synaptic vesicles, which can
be recycled and refilled close to release sites, DCVs must be replenished by de
novo synthesis in the cell body. Here, we dissect DCV cell biology in vivo in
a Caenorhabditis elegans sensory neuron whose tonic activity we can control using
a natural stimulus. We express fluorescently tagged neuropeptides in the neuron
and define parameters that describe their subcellular distribution. We measure
these parameters at high and low neural activity in 187 mutants defective in proteins
implicated in membrane traffic, neuroendocrine secretion, and neuronal or synaptic
activity. Using unsupervised hierarchical clustering methods, we analyze these
data and identify 62 groups of genes with similar mutant phenotypes. We explore
the function of a subset of these groups. We recapitulate many previous findings,
validating our paradigm. We uncover a large battery of proteins involved in recycling
DCV membrane proteins, something hitherto poorly explored. We show that the unfolded
protein response promotes DCV production, which may contribute to intertissue
communication of stress. We also find evidence that different mechanisms of priming
and exocytosis may operate at high and low neural activity. Our work provides
a defined framework to study DCV biology at different neural activity levels.

text: Efficient molecular switching in confined spaces is critical for the successful
development of artificial molecular machines. However, molecular switching events
often entail large structural changes and therefore require conformational freedom,
which is typically limited under confinement conditions. Here, we investigated
the behavior of azobenzene—the key building block of light-controlled molecular
machines—in a confined environment that is flexible and can adapt its shape to
that of the bound guest. To this end, we encapsulated several structurally diverse
azobenzenes within the cavity of a flexible, water-soluble coordination cage,
and investigated their light-responsive behavior. Using UV/Vis absorption spectroscopy
and a combination of NMR methods, we showed that each of the encapsulated azobenzenes
exhibited distinct switching properties. An azobenzene forming a 1:1 host–guest
inclusion complex could be efficiently photoisomerized in a reversible fashion.
In contrast, successful switching in inclusion complexes incorporating two azobenzene
guests was dependent on the availability of free cages in the system, and it involved
reversible trafficking of azobenzene between the cages. In the absence of extra
cages, photoswitching was either suppressed or it involved expulsion of azobenzene
from the cage and consequently its precipitation from the solution. This finding
was utilized to develop an information storage medium in which messages could
be written and erased in a reversible fashion using light.

text: Idealized simulations of tropical moist convection have revealed that clouds
can spontaneously clump together in a process called self-aggregation. This results
in a state where a moist cloudy region with intense deep convection is surrounded
by extremely dry subsiding air devoid of deep convection. Because of the idealized
settings of the simulations where it was discovered, the relevance of self-aggregation
to the real world is still debated. Here, we show that self-aggregation feedbacks
play a leading-order role in the spontaneous genesis of tropical cyclones in cloud-resolving
simulations. Those feedbacks accelerate the cyclogenesis process by a factor of
2, and the feedbacks contributing to the cyclone formation show qualitative and
quantitative agreement with the self-aggregation process. Once the cyclone is
formed, wind-induced surface heat exchange (WISHE) effects dominate, although
we find that self-aggregation feedbacks have a small but nonnegligible contribution
to the maintenance of the mature cyclone. Our results suggest that self-aggregation,
and the framework developed for its study, can help shed more light into the physical
processes leading to cyclogenesis and cyclone intensification. In particular,
our results point out the importance of the longwave radiative cooling outside
the cyclone.

text: The DEMETER (DME) DNA glycosylase catalyzes genome-wide DNA demethylation
and is required for endosperm genomic imprinting and embryo viability. Targets
of DME-mediated DNA demethylation reside in small, euchromatic, AT-rich transposons
and at the boundaries of large transposons, but how DME interacts with these diverse
chromatin states is unknown. The STRUCTURE SPECIFIC RECOGNITION PROTEIN 1 (SSRP1)
subunit of the chromatin remodeler FACT (facilitates chromatin transactions),
was previously shown to be involved in the DME-dependent regulation of genomic
imprinting in Arabidopsis endosperm. Therefore, to investigate the interaction
between DME and chromatin, we focused on the activity of the two FACT subunits,
SSRP1 and SUPPRESSOR of TY16 (SPT16), during reproduction in Arabidopsis. We found
that FACT colocalizes with nuclear DME in vivo, and that DME has two classes of
target sites, the first being euchromatic and accessible to DME, but the second,
representing over half of DME targets, requiring the action of FACT for DME-mediated
DNA demethylation genome-wide. Our results show that the FACT-dependent DME targets
are GC-rich heterochromatin domains with high nucleosome occupancy enriched with
H3K9me2 and H3K27me1. Further, we demonstrate that heterochromatin-associated
linker histone H1 specifically mediates the requirement for FACT at a subset of
DME-target loci. Overall, our results demonstrate that FACT is required for DME
targeting by facilitating its access to heterochromatin.

text: Supraglacial ice cliffs exist on debris-covered glaciers worldwide, but despite
their importance as melt hot spots, their life cycle is little understood. Early
field observations had advanced a hypothesis of survival of north-facing and disappearance
of south-facing cliffs, which is central for predicting the contribution of cliffs
to total glacier mass losses. Their role as windows of energy transfer suggests
they may explain the anomalously high mass losses of debris-covered glaciers in
High Mountain Asia (HMA) despite the insulating debris, currently at the center
of a debated controversy. We use a 3D model of cliff evolution coupled to very
high-resolution topographic data to demonstrate that ice cliffs facing south (in
the Northern Hemisphere) disappear within a few months due to enhanced solar radiation
receipts and that aspect is the key control on cliffs evolution. We reproduce
continuous flattening of south-facing cliffs, a result of their vertical gradient
of incoming solar radiation and sky view factor. Our results establish that only
north-facing cliffs are recurrent features and thus stable contributors to the
melting of debris-covered glaciers. Satellite observations and mass balance modeling
confirms that few south-facing cliffs of small size exist on the glaciers of Langtang,
and their contribution to the glacier volume losses is very small (∼1%). This
has major implications for the mass balance of HMA debris-covered glaciers as
it provides the basis for new parameterizations of cliff evolution and distribution
to constrain volume losses in a region where glaciers are highly relevant as water
sources for millions of people.

text: 'Nervous systems use excitatory cell assemblies to encode and represent sensory
percepts. Similarly, synaptically connected cell assemblies or "engrams" are thought
to represent memories of past experience. Multiple lines of recent evidence indicate
that brain systems create and use inhibitory replicas of excitatory representations
for important cognitive functions. Such matched "inhibitory engrams" can form
through homeostatic potentiation of inhibition onto postsynaptic cells that show
increased levels of excitation. Inhibitory engrams can reduce behavioral responses
to familiar stimuli, thereby resulting in behavioral habituation. In addition,
by preventing inappropriate activation of excitatory memory engrams, inhibitory
engrams can make memories quiescent, stored in a latent form that is available
for context-relevant activation. In neural networks with balanced excitatory and
inhibitory engrams, the release of innate responses and recall of associative
memories can occur through focused disinhibition. Understanding mechanisms that
regulate the formation and expression of inhibitory engrams in vivo may help not
only to explain key features of cognition but also to provide insight into transdiagnostic
traits associated with psychiatric conditions such as autism, schizophrenia, and
posttraumatic stress disorder. '

text: Quantifying the effects of inbreeding is critical to characterizing the genetic
architecture of complex traits. This study highlights through theory and simulations
the strengths and shortcomings of three SNP-based inbreeding measures commonly
used to estimate inbreeding depression (ID). We demonstrate that heterogeneity
in linkage disequilibrium (LD) between causal variants and SNPs biases ID estimates,
and we develop an approach to correct this bias using LD and minor allele frequency
stratified inference (LDMS). We quantified ID in 25 traits measured in ∼140,000
participants of the UK Biobank, using LDMS, and confirmed previously published
ID for 4 traits. We find unique evidence of ID for handgrip strength, waist/hip
ratio, and visual and auditory acuity (ID between −2.3 and −5.2 phenotypic SDs
for complete inbreeding; P<0.001). Our results illustrate that a careful choice
of the measure of inbreeding combined with LDMS stratification improves both detection
and quantification of ID using SNP data.

text: Recent advances in designing metamaterials have demonstrated that global mechanical
properties of disordered spring networks can be tuned by selectively modifying
only a small subset of bonds. Here, using a computationally efficient approach,
we extend this idea to tune more general properties of networks. With nearly complete
success, we are able to produce a strain between any two target nodes in a network
in response to an applied source strain on any other pair of nodes by removing
only ∼1% of the bonds. We are also able to control multiple pairs of target nodes,
each with a different individual response, from a single source, and to tune multiple
independent source/target responses simultaneously into a network. We have fabricated
physical networks in macroscopic 2D and 3D systems that exhibit these responses.
This work is inspired by the long-range coupled conformational changes that constitute
allosteric function in proteins. The fact that allostery is a common means for
regulation in biological molecules suggests that it is a relatively easy property
to develop through evolution. In analogy, our results show that long-range coupled
mechanical responses are similarly easy to achieve in disordered networks.

text: Controlling motion at the microscopic scale is a fundamental goal in the development
of biologically inspired systems. We show that the motion of active, self-propelled
colloids can be sufficiently controlled for use as a tool to assemble complex
structures such as braids and weaves out of microscopic filaments. Unlike typical
self-assembly paradigms, these structures are held together by geometric constraints
rather than adhesive bonds. The out-of-equilibrium assembly that we propose involves
precisely controlling the 2D motion of active colloids so that their path has
a nontrivial topology. We demonstrate with proof-of-principle Brownian dynamics
simulations that, when the colloids are attached to long semiflexible filaments,
this motion causes the filaments to braid. The ability of the active particles
to provide sufficient force necessary to bend the filaments into a braid depends
on a number of factors, including the self-propulsion mechanism, the properties
of the filament, and the maximum curvature in the braid. Our work demonstrates
that nonequilibrium assembly pathways can be designed using active particles.

text: Animals adjust their behavioral priorities according to momentary needs and
prior experience. We show that Caenorhabditis elegans changes how it processes
sensory information according to the oxygen environment it experienced recently.
C. elegans acclimated to 7% O2 are aroused by CO2 and repelled by pheromones that
attract animals acclimated to 21% O2. This behavioral plasticity arises from prolonged
activity differences in a circuit that continuously signals O2 levels. A sustained
change in the activity of O2-sensing neurons reprograms the properties of their
postsynaptic partners, the RMG hub interneurons. RMG is gap-junctionally coupled
to the ASK and ADL pheromone sensors that respectively drive pheromone attraction
and repulsion. Prior O2 experience has opposite effects on the pheromone responsiveness
of these neurons. These circuit changes provide a physiological correlate of altered
pheromone valence. Our results suggest C. elegans stores a memory of recent O2
experience in the RMG circuit and illustrate how a circuit is flexibly sculpted
to guide behavioral decisions in a context-dependent manner.

text: 'Electric charges are conserved. The same would be expected to hold for magnetic
charges, yet magnetic monopoles have never been observed. It is therefore surprising
that the laws of nonequilibrium thermodynamics, combined with Maxwell’s equations,
suggest that colloidal particles heated or cooled in certain polar or paramagnetic
solvents may behave as if they carry an electric/magnetic charge. Here, we present
numerical simulations that show that the field distribution around a pair of such
heated/cooled colloidal particles agrees quantitatively with the theoretical predictions
for a pair of oppositely charged electric or magnetic monopoles. However, in other
respects, the nonequilibrium colloidal particles do not behave as monopoles: They
cannot be moved by a homogeneous applied field. The numerical evidence for the
monopole-like fields around heated/cooled colloidal particles is crucial because
the experimental and numerical determination of forces between such colloidal
particles would be complicated by the presence of other effects, such as thermophoresis.'

text: During spore formation in Bacillus subtilis a transenvelope complex is assembled
across the double membrane that separates the mother cell and forespore. This
complex (called the “A–Q complex”) is required to maintain forespore development
and is composed of proteins with remote homology to components of type II, III,
and IV secretion systems found in Gram-negative bacteria. Here, we show that one
of these proteins, SpoIIIAG, which has remote homology to ring-forming proteins
found in type III secretion systems, assembles into an oligomeric ring in the
periplasmic-like space between the two membranes. Three-dimensional reconstruction
of images generated by cryo-electron microscopy indicates that the SpoIIIAG ring
has a cup-and-saucer architecture with a 6-nm central pore. Structural modeling
of SpoIIIAG generated a 24-member ring with dimensions similar to those of the
EM-derived saucer. Point mutations in the predicted oligomeric interface disrupted
ring formation in vitro and impaired forespore gene expression and efficient spore
formation in vivo. Taken together, our data provide strong support for the model
in which the A–Q transenvelope complex contains a conduit that connects the mother
cell and forespore. We propose that a set of stacked rings spans the intermembrane
space, as has been found for type III secretion systems.

text: We propose a Widom-like scaling ansatz for the critical jamming transition.
Our ansatz for the elastic energy shows that the scaling of the energy, compressive
strain, shear strain, system size, pressure, shear stress, bulk modulus, and shear
modulus are all related to each other via scaling relations, with only three independent
scaling exponents. We extract the values of these exponents from already known
numerical or theoretical results, and we numerically verify the resulting predictions
of the scaling theory for the energy and residual shear stress. We also derive
a scaling relation between pressure and residual shear stress that yields insight
into why the shear and bulk moduli scale differently. Our theory shows that the
jamming transition exhibits an emergent scale invariance, setting the stage for
the potential development of a renormalization group theory for jamming.

text: Despite the recent rapid progress in cryo-electron microscopy (cryo-EM), there
still exist ample opportunities for improvement in sample preparation. Macromolecular
complexes may disassociate or adopt nonrandom orientations against the extended
air–water interface that exists for a short time before the sample is frozen.
We designed a hollow support structure using 3D DNA origami to protect complexes
from the detrimental effects of cryo-EM sample preparation. For a first proof-of-principle,
we concentrated on the transcription factor p53, which binds to specific DNA sequences
on double-stranded DNA. The support structures spontaneously form monolayers of
preoriented particles in a thin film of water, and offer advantages in particle
picking and sorting. By controlling the position of the binding sequence on a
single helix that spans the hollow support structure, we also sought to control
the orientation of individual p53 complexes. Although the latter did not yet yield
the desired results, the support structures did provide partial information about
the relative orientations of individual p53 complexes. We used this information
to calculate a tomographic 3D reconstruction, and refined this structure to a
final resolution of ∼15 Å. This structure settles an ongoing debate about the
symmetry of the p53 tetramer bound to DNA.

text: Cytosine DNA methylation regulates the expression of eukaryotic genes and
transposons. Methylation is copied by methyltransferases after DNA replication,
which results in faithful transmission of methylation patterns during cell division
and, at least in flowering plants, across generations. Transgenerational inheritance
is mediated by a small group of cells that includes gametes and their progenitors.
However, methylation is usually analyzed in somatic tissues that do not contribute
to the next generation, and the mechanisms of transgenerational inheritance are
inferred from such studies. To gain a better understanding of how DNA methylation
is inherited, we analyzed purified Arabidopsis thaliana sperm and vegetative cells-the
cell types that comprise pollen-with mutations in the DRM, CMT2, and CMT3 methyltransferases.
We find that DNA methylation dependency on these enzymes is similar in sperm,
vegetative cells, and somatic tissues, although DRM activity extends into heterochromatin
in vegetative cells, likely reflecting transcription of heterochromatic transposons
in this cell type. We also show that lack of histone H1, which elevates heterochromatic
DNA methylation in somatic tissues, does not have this effect in pollen. Instead,
levels of CG methylation in wild-type sperm and vegetative cells, as well as in
wild-type microspores from which both pollen cell types originate, are substantially
higher than in wild-type somatic tissues and similar to those of H1-depleted roots.
Our results demonstrate that the mechanisms of methylation maintenance are similar
between pollen and somatic cells, but the efficiency of CG methylation is higher
in pollen, allowing methylation patterns to be accurately inherited across generations.
