text: De novo heterozygous variants in KCNC2 encoding the voltage-gated potassium
(K+) channel subunit Kv3.2 are a recently described cause of developmental and
epileptic encephalopathy (DEE). A de novo variant in KCNC2 c.374G > A (p.Cys125Tyr)
was identified via exome sequencing in a patient with DEE. Relative to wild-type
Kv3.2, Kv3.2-p.Cys125Tyr induces K+ currents exhibiting a large hyperpolarizing
shift in the voltage dependence of activation, accelerated activation, and delayed
deactivation consistent with a relative stabilization of the open conformation,
along with increased current density. Leveraging the cryogenic electron microscopy
(cryo-EM) structure of Kv3.1, molecular dynamic simulations suggest that a strong
π-π stacking interaction between the variant Tyr125 and Tyr156 in the α-6 helix
of the T1 domain promotes a relative stabilization of the open conformation of
the channel, which underlies the observed gain of function. A multicompartment
computational model of a Kv3-expressing parvalbumin-positive cerebral cortex fast-spiking
γ-aminobutyric acidergic (GABAergic) interneuron (PV-IN) demonstrates how the
Kv3.2-Cys125Tyr variant impairs neuronal excitability and dysregulates inhibition
in cerebral cortex circuits to explain the resulting epilepsy.

text: "Self-replication of amyloid fibrils via secondary nucleation is an intriguing
physicochemical phenomenon in which existing fibrils catalyze the formation of
their own copies. The molecular events behind this fibril surface-mediated process
remain largely inaccessible to current structural and imaging techniques. Using
statistical mechanics, computer modeling, and chemical kinetics, we show that
the catalytic structure of the fibril surface can be inferred from the aggregation
behavior in the presence and absence of a fibril-binding inhibitor. We apply our
approach to the case of Alzheimer’s A\r\n amyloid fibrils formed in the presence
of proSP-C Brichos inhibitors. We find that self-replication of A\r\n fibrils
occurs on small catalytic sites on the fibril surface, which are far apart from
each other, and each of which can be covered by a single Brichos inhibitor."

text: As a crucial nitrogen source, nitrate (NO3−) is a key nutrient for plants.
Accordingly, root systems adapt to maximize NO3− availability, a developmental
regulation also involving the phytohormone auxin. Nonetheless, the molecular mechanisms
underlying this regulation remain poorly understood. Here, we identify low-nitrate-resistant
mutant (lonr) in Arabidopsis (Arabidopsis thaliana), whose root growth fails to
adapt to low-NO3− conditions. lonr2 is defective in the high-affinity NO3− transporter
NRT2.1. lonr2 (nrt2.1) mutants exhibit defects in polar auxin transport, and their
low-NO3−-induced root phenotype depends on the PIN7 auxin exporter activity. NRT2.1
directly associates with PIN7 and antagonizes PIN7-mediated auxin efflux depending
on NO3− levels. These results reveal a mechanism by which NRT2.1 in response to
NO3− limitation directly regulates auxin transport activity and, thus, root growth.
This adaptive mechanism contributes to the root developmental plasticity to help
plants cope with changes in NO3− availability.

text: How do statistical dependencies in measurement noise influence high-dimensional
inference? To answer this, we study the paradigmatic spiked matrix model of principal
components analysis (PCA), where a rank-one matrix is corrupted by additive noise.
We go beyond the usual independence assumption on the noise entries, by drawing
the noise from a low-order polynomial orthogonal matrix ensemble. The resulting
noise correlations make the setting relevant for applications but analytically
challenging. We provide characterization of the Bayes optimal limits of inference
in this model. If the spike is rotation invariant, we show that standard spectral
PCA is optimal. However, for more general priors, both PCA and the existing approximate
message-passing algorithm (AMP) fall short of achieving the information-theoretic
limits, which we compute using the replica method from statistical physics. We
thus propose an AMP, inspired by the theory of adaptive Thouless–Anderson–Palmer
equations, which is empirically observed to saturate the conjectured theoretical
limit. This AMP comes with a rigorous state evolution analysis tracking its performance.
Although we focus on specific noise distributions, our methodology can be generalized
to a wide class of trace matrix ensembles at the cost of more involved expressions.
Finally, despite the seemingly strong assumption of rotation-invariant noise,
our theory empirically predicts algorithmic performance on real data, pointing
at strong universality properties.

text: 'Traditionally, nuclear spin is not considered to affect biological processes.
Recently, this has changed as isotopic fractionation that deviates from classical
mass dependence was reported both in vitro and in vivo. In these cases, the isotopic
effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects
using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial
dioxygen production system and biological aquaporin channels in cells. We observe
that oxygen dynamics in chiral environments (in particular its transport) depend
on nuclear spin, suggesting future applications for controlled isotope separation
to be used, for instance, in NMR. To demonstrate the mechanism behind our findings,
we formulate theoretical models based on a nuclear-spin-enhanced switch between
electronic spin states. Accounting for the role of nuclear spin in biology can
provide insights into the role of quantum effects in living systems and help inspire
the development of future biotechnology solutions.'

text: So-called spontaneous activity is a central hallmark of most nervous systems.
Such non-causal firing is contrary to the tenet of spikes as a means of communication,
and its purpose remains unclear. We propose that self-initiated firing can serve
as a release valve to protect neurons from the toxic conditions arising in mitochondria
from lower-than-baseline energy consumption. To demonstrate the viability of our
hypothesis, we built a set of models that incorporate recent experimental results
indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP),
adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing.
We explore the relationship of metabolic cost of spiking with its effect on the
temporal patterning of spikes and reproduce experimentally observed changes in
intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with
ROS-modulated potassium channels. We also show that metabolic spiking homeostasis
can produce indefinitely sustained avalanche dynamics in cortical circuits. Our
theory can account for key features of neuronal activity observed in many studies
ranging from ion channel function all the way to resting state dynamics. We finish
with a set of experimental predictions that would confirm an integrated, crucial
role for metabolically regulated spiking and firmly link metabolic homeostasis
and neuronal function.

text: Glaciers are key components of the mountain water towers of Asia and are vital
for downstream domestic, agricultural, and industrial uses. The glacier mass loss
rate over the southeastern Tibetan Plateau is among the highest in Asia and has
accelerated in recent decades. This acceleration has been attributed to increased
warming, but the mechanisms behind these glaciers’ high sensitivity to warming
remain unclear, while the influence of changes in precipitation over the past
decades is poorly quantified. Here, we reconstruct glacier mass changes and catchment
runoff since 1975 at a benchmark glacier, Parlung No. 4, to shed light on the
drivers of recent mass losses for the monsoonal, spring-accumulation glaciers
of the Tibetan Plateau. Our modeling demonstrates how a temperature increase (mean
of 0.39∘C ⋅dec−1since 1990) has accelerated
mass loss rates by altering both the ablation and accumulation regimes in a complex
manner. The majority of the post-2000 mass loss occurred during the monsoon months,
caused by simultaneous decreases in the solid precipitation ratio (from 0.70 to
0.56) and precipitation amount (–10%), leading to reduced monsoon accumulation
(–26%). Higher solid precipitation in spring (+18%) during the last two decades
was increasingly important in mitigating glacier mass loss by providing mass to
the glacier and protecting it from melting in the early monsoon. With bare ice
exposed to warmer temperatures for longer periods, icemelt and catchment discharge
have unsustainably intensified since the start of the 21st century, raising concerns
for long-term water supply and hazard occurrence in the region.

text: Despite the growing interest in using chemical genetics in plant research,
small molecule target identification remains a major challenge. The cellular thermal
shift assay coupled with high-resolution mass spectrometry (CETSA MS) that monitors
changes in the thermal stability of proteins caused by their interactions with
small molecules, other proteins, or posttranslational modifications, allows the
discovery of drug targets or the study of protein–metabolite and protein–protein
interactions mainly in mammalian cells. To showcase the applicability of this
method in plants, we applied CETSA MS to intact Arabidopsis thaliana cells and
identified the thermal proteome of the plant-specific glycogen synthase kinase
3 (GSK3) inhibitor, bikinin. A comparison between the thermal and the phosphoproteomes
of bikinin revealed the auxin efflux carrier PIN-FORMED1 (PIN1) as a substrate
of the Arabidopsis GSK3s that negatively regulate the brassinosteroid signaling.
We established that PIN1 phosphorylation by the GSK3s is essential for maintaining
its intracellular polarity that is required for auxin-mediated regulation of vascular
patterning in the leaf, thus revealing cross-talk between brassinosteroid and
auxin signaling.

text: When Mendel’s work was rediscovered in 1900, and extended to establish classical
genetics, it was initially seen in opposition to Darwin’s theory of evolution
by natural selection on continuous variation, as represented by the biometric
research program that was the foundation of quantitative genetics. As Fisher,
Haldane, and Wright established a century ago, Mendelian inheritance is exactly
what is needed for natural selection to work efficiently. Yet, the synthesis remains
unfinished. We do not understand why sexual reproduction and a fair meiosis predominate
in eukaryotes, or how far these are responsible for their diversity and complexity.
Moreover, although quantitative geneticists have long known that adaptive variation
is highly polygenic, and that this is essential for efficient selection, this
is only now becoming appreciated by molecular biologists—and we still do not have
a good framework for understanding polygenic variation or diffuse function.

text: Plant cell growth responds rapidly to various stimuli, adapting architecture
to environmental changes. Two major endogenous signals regulating growth are the
phytohormone auxin and the secreted peptides rapid alkalinization factors (RALFs).
Both trigger very rapid cellular responses and also exert long-term effects [Du
et al., Annu. Rev. Plant Biol. 71, 379–402 (2020); Blackburn et al., Plant Physiol.
182, 1657–1666 (2020)]. However, the way, in which these distinct signaling pathways
converge to regulate growth, remains unknown. Here, using vertical confocal microscopy
combined with a microfluidic chip, we addressed the mechanism of RALF action on
growth. We observed correlation between RALF1-induced rapid Arabidopsis thaliana
root growth inhibition and apoplast alkalinization during the initial phase of
the response, and revealed that RALF1 reversibly inhibits primary root growth
through apoplast alkalinization faster than within 1 min. This rapid apoplast
alkalinization was the result of RALF1-induced net H+ influx and was mediated
by the receptor FERONIA (FER). Furthermore, we investigated the cross-talk between
RALF1 and the auxin signaling pathways during root growth regulation. The results
showed that RALF-FER signaling triggered auxin signaling with a delay of approximately
1 h by up-regulating auxin biosynthesis, thus contributing to sustained RALF1-induced
growth inhibition. This biphasic RALF1 action on growth allows plants to respond
rapidly to environmental stimuli and also reprogram growth and development in
the long term.

text: Genetically informed, deep-phenotyped biobanks are an important research resource
and it is imperative that the most powerful, versatile, and efficient analysis
approaches are used. Here, we apply our recently developed Bayesian grouped mixture
of regressions model (GMRM) in the UK and Estonian Biobanks and obtain the highest
genomic prediction accuracy reported to date across 21 heritable traits. When
compared to other approaches, GMRM accuracy was greater than annotation prediction
models run in the LDAK or LDPred-funct software by 15% (SE 7%) and 14% (SE 2%),
respectively, and was 18% (SE 3%) greater than a baseline BayesR model without
single-nucleotide polymorphism (SNP) markers grouped into minor allele frequency–linkage
disequilibrium (MAF-LD) annotation categories. For height, the prediction accuracy
R2 was 47% in a UK Biobank holdout sample, which was 76% of the estimated h2SNP.
We then extend our GMRM prediction model to provide mixed-linear model association
(MLMA) SNP marker estimates for genome-wide association (GWAS) discovery, which
increased the independent loci detected to 16,162 in unrelated UK Biobank individuals,
compared to 10,550 from BoltLMM and 10,095 from Regenie, a 62 and 65% increase,
respectively. The average χ2 value of the leading markers increased by 15.24 (SE
0.41) for every 1% increase in prediction accuracy gained over a baseline BayesR
model across the traits. Thus, we show that modeling genetic associations accounting
for MAF and LD differences among SNP markers, and incorporating prior knowledge
of genomic function, is important for both genomic prediction and discovery in
large-scale individual-level studies.

text: Mineral nutrition is one of the key environmental factors determining plant
development and growth. Nitrate is the major form of macronutrient nitrogen that
plants take up from the soil. Fluctuating availability or deficiency of this element
severely limits plant growth and negatively affects crop production in the agricultural
system. To cope with the heterogeneity of nitrate distribution in soil, plants
evolved a complex regulatory mechanism that allows rapid adjustment of physiological
and developmental processes to the status of this nutrient. The root, as a major
exploitation organ that controls the uptake of nitrate to the plant body, acts
as a regulatory hub that, according to nitrate availability, coordinates the growth
and development of other plant organs. Here, we identified a regulatory framework,
where cytokinin response factors (CRFs) play a central role as a molecular readout
of the nitrate status in roots to guide shoot adaptive developmental response.
We show that nitrate-driven activation of NLP7, a master regulator of nitrate
response in plants, fine tunes biosynthesis of cytokinin in roots and its translocation
to shoots where it enhances expression of CRFs. CRFs, through direct transcriptional
regulation of PIN auxin transporters, promote the flow of auxin and thereby stimulate
the development of shoot organs.

text: Primary nucleation is the fundamental event that initiates the conversion
of proteins from their normal physiological forms into pathological amyloid aggregates
associated with the onset and development of disorders including systemic amyloidosis,
as well as the neurodegenerative conditions Alzheimer’s and Parkinson’s diseases.
It has become apparent that the presence of surfaces can dramatically modulate
nucleation. However, the underlying physicochemical parameters governing this
process have been challenging to elucidate, with interfaces in some cases having
been found to accelerate aggregation, while in others they can inhibit the kinetics
of this process. Here we show through kinetic analysis that for three different
fibril-forming proteins, interfaces affect the aggregation reaction mainly through
modulating the primary nucleation step. Moreover, we show through direct measurements
of the Gibbs free energy of adsorption, combined with theory and coarse-grained
computer simulations, that overall nucleation rates are suppressed at high and
at low surface interaction strengths but significantly enhanced at intermediate
strengths, and we verify these regimes experimentally. Taken together, these results
provide a quantitative description of the fundamental process which triggers amyloid
formation and shed light on the key factors that control this process.

text: 'Selection accumulates information in the genome—it guides stochastically
evolving populations toward states (genotype frequencies) that would be unlikely
under neutrality. This can be quantified as the Kullback–Leibler (KL) divergence
between the actual distribution of genotype frequencies and the corresponding
neutral distribution. First, we show that this population-level information sets
an upper bound on the information at the level of genotype and phenotype, limiting
how precisely they can be specified by selection. Next, we study how the accumulation
and maintenance of information is limited by the cost of selection, measured as
the genetic load or the relative fitness variance, both of which we connect to
the control-theoretic KL cost of control. The information accumulation rate is
upper bounded by the population size times the cost of selection. This bound is
very general, and applies across models (Wright–Fisher, Moran, diffusion) and
to arbitrary forms of selection, mutation, and recombination. Finally, the cost
of maintaining information depends on how it is encoded: Specifying a single allele
out of two is expensive, but one bit encoded among many weakly specified loci
(as in a polygenic trait) is cheap.'

text: Unlike crystalline atomic and ionic solids, texture development due to crystallographically
preferred growth in colloidal crystals is less studied. Here we investigate the
underlying mechanisms of the texture evolution in an evaporation-induced colloidal
assembly process through experiments, modeling, and theoretical analysis. In this
widely used approach to obtain large-area colloidal crystals, the colloidal particles
are driven to the meniscus via the evaporation of a solvent or matrix precursor
solution where they close-pack to form a face-centered cubic colloidal assembly.
Via two-dimensional large-area crystallographic mapping, we show that the initial
crystal orientation is dominated by the interaction of particles with the meniscus,
resulting in the expected coalignment of the close-packed direction with the local
meniscus geometry. By combining with crystal structure analysis at a single-particle
level, we further reveal that, at the later stage of self-assembly, however, the
colloidal crystal undergoes a gradual rotation facilitated by geometrically necessary
dislocations (GNDs) and achieves a large-area uniform crystallographic orientation
with the close-packed direction perpendicular to the meniscus and parallel to
the growth direction. Classical slip analysis, finite element-based mechanical
simulation, computational colloidal assembly modeling, and continuum theory unequivocally
show that these GNDs result from the tensile stress field along the meniscus direction
due to the constrained shrinkage of the colloidal crystal during drying. The generation
of GNDs with specific slip systems within individual grains leads to crystallographic
rotation to accommodate the mechanical stress. The mechanistic understanding reported
here can be utilized to control crystallographic features of colloidal assemblies,
and may provide further insights into crystallographically preferred growth in
synthetic, biological, and geological crystals.

text: 'The inverse problem of designing component interactions to target emergent
structure is fundamental to numerous applications in biotechnology, materials
science, and statistical physics. Equally important is the inverse problem of
designing emergent kinetics, but this has received considerably less attention.
Using recent advances in automatic differentiation, we show how kinetic pathways
can be precisely designed by directly differentiating through statistical physics
models, namely free energy calculations and molecular dynamics simulations. We
consider two systems that are crucial to our understanding of structural self-assembly:
bulk crystallization and small nanoclusters. In each case, we are able to assemble
precise dynamical features. Using gradient information, we manipulate interactions
among constituent particles to tune the rate at which these systems yield specific
structures of interest. Moreover, we use this approach to learn nontrivial features
about the high-dimensional design space, allowing us to accurately predict when
multiple kinetic features can be simultaneously and independently controlled.
These results provide a concrete and generalizable foundation for studying nonstructural
self-assembly, including kinetic properties as well as other complex emergent
properties, in a vast array of systems.'

text: Electrodepositing insulating lithium peroxide (Li2O2) is the key process during
discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility.
Current understanding states that the partition between surface adsorbed and dissolved
lithium superoxide governs whether Li2O2 grows as a conformal surface film or
larger particles, leading to low or high capacities, respectively. However, better
understanding governing factors for Li2O2 packing density and capacity requires
structural sensitive in situ metrologies. Here, we establish in situ small- and
wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2
phase evolution with atomic to submicrometer resolution during cycling a custom-built
in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving
rich quantitative structural information from complex multiphase systems. Surprisingly,
we find that features are absent that would point at a Li2O2 surface film formed
via two consecutive electron transfers, even in poorly solvating electrolytes
thought to be prototypical for surface growth. All scattering data can be modeled
by stacks of thin Li2O2 platelets potentially forming large toroidal particles.
Li2O2 solution growth is further justified by rotating ring-disk electrode measurements
and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2
particles, but there is no transition to an electronically passivating, conformal
Li2O2 coating. Hence, mass transport of reactive species rather than electronic
transport through a Li2O2 film limits the discharge capacity. Provided that species
mobilities and carbon surface areas are high, this allows for high discharge capacities
even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism
ought to be reconsidered.

text: In nerve cells the genes encoding for α2δ subunits of voltage-gated calcium
channels have been linked to synaptic functions and neurological disease. Here
we show that α2δ subunits are essential for the formation and organization of
glutamatergic synapses. Using a cellular α2δ subunit triple-knockout/knockdown
model, we demonstrate a failure in presynaptic differentiation evidenced by defective
presynaptic calcium channel clustering and calcium influx, smaller presynaptic
active zones, and a strongly reduced accumulation of presynaptic vesicle-associated
proteins (synapsin and vGLUT). The presynaptic defect is associated with the downscaling
of postsynaptic AMPA receptors and the postsynaptic density. The role of α2δ isoforms
as synaptic organizers is highly redundant, as each individual α2δ isoform can
rescue presynaptic calcium channel trafficking and expression of synaptic proteins.
Moreover, α2δ-2 and α2δ-3 with mutated metal ion-dependent adhesion sites can
fully rescue presynaptic synapsin expression but only partially calcium channel
trafficking, suggesting that the regulatory role of α2δ subunits is independent
from its role as a calcium channel subunit. Our findings influence the current
view on excitatory synapse formation. First, our study suggests that postsynaptic
differentiation is secondary to presynaptic differentiation. Second, the dependence
of presynaptic differentiation on α2δ implicates α2δ subunits as potential nucleation
points for the organization of synapses. Finally, our results suggest that α2δ
subunits act as transsynaptic organizers of glutamatergic synapses, thereby aligning
the synaptic active zone with the postsynaptic density.

text: Turbulence generally arises in shear flows if velocities and hence, inertial
forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit
disordered motion even at vanishing inertia. Intermediate between these cases,
a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed
in a narrow Reynolds number interval. We here determine the origin of EIT in experiments
and show that characteristic EIT structures can be detected across an unexpectedly
wide range of parameters. Close to onset, a pattern of chevron-shaped streaks
emerges in qualitative agreement with linear and weakly nonlinear theory. However,
in experiments, the dynamics remain weakly chaotic, and the instability can be
traced to far lower Reynolds numbers than permitted by theory. For increasing
inertia, the flow undergoes a transformation to a wall mode composed of inclined
near-wall streaks and shear layers. This mode persists to what is known as the
“maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic
flows across more than three orders of magnitude in Reynolds number.

text: 'Parent-of-origin–dependent gene expression in mammals and flowering plants
results from differing chromatin imprints (genomic imprinting) between maternally
and paternally inherited alleles. Imprinted gene expression in the endosperm of
seeds is associated with localized hypomethylation of maternally but not paternally
inherited DNA, with certain small RNAs also displaying parent-of-origin–specific
expression. To understand the evolution of imprinting mechanisms in Oryza sativa
(rice), we analyzed imprinting divergence among four cultivars that span both
japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted
genes are imprinted across cultivars and enriched for functions in chromatin and
transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted
genes display divergent imprinting. Analyses of DNA methylation and small RNAs
revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed
DNA methylation, frequently overlap genes, and are imprinted four times more often
than genes. However, imprinting divergence most often correlated with local DNA
methylation epimutations (9 of 17 assessable loci), which were largely stable
within subspecies. Small insertion/deletion events and transposable element insertions
accompanied 4 of the 9 locally epimutated loci and associated with imprinting
divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic
variation occurred at key regulatory regions—the promoter and transcription start
site of maternally biased genes, and the promoter and gene body of paternally
biased genes. Our results reinforce models for the role of maternal-specific DNA
hypomethylation in imprinting of both maternally and paternally biased genes,
and highlight the role of transposition and epimutation in rice imprinting evolution.'
