text: Stellar wind mass loss of massive stars is often assumed to depend on their
metallicity Z. Therefore, evolutionary models predict that massive stars in lower-Z
environments are able to retain more of their hydrogen-rich layers and evolve
into brighter cool supergiants (cool SGs; Teff < 7 kK). Surprisingly, in galaxies
in the metallicity range 0.2 ≲ Z/Z⊙ ≲ 1.5, previous studies have not found a metallicity
dependence on the upper luminosity limit Lmax of cool SGs. Here, we add four galaxies
to the sample studied for this purpose with data from the Hubble Space Telescope
and the James Webb Space Telescope (JWST). Observations of the extremely metal-poor
dwarf galaxy I Zw 18 from JWST allow us to extend the studied metallicity range
down to Z/Z⊙ ≈ 1/40. For cool SGs in all studied galaxies, including I Zw 18,
we find a constant value of Lmax ≈ 105.6 L⊙, similar to literature results for
0.2 ≲ Z/Z⊙ ≲ 1.5. In I Zw 18 and the other studied galaxies, the presence of Wolf-Rayet
stars has been previously inferred. Although we cannot rule out that some of them
become intermediate-temperature objects, this paints a picture in which evolved
stars with L > 105.6 L⊙ burn helium as hot, helium-rich stars down to extremely
low metallicity. We argue that metallicity-independent late-phase mass loss would
be the most likely mechanism responsible for this. Regardless of the exact stripping
mechanism (winds or, for example, binary interaction), for the Early Universe
our results imply a limitation on black hole masses and a contribution of stars
born with M ≳ 30 M⊙ to its surprisingly strong nitrogen enrichment. We propose
a scenario in which single stars at low metallicity emit sufficiently hard ionizing
radiation to produce He II and C IV lines. In this scenario, late-phase metallicity-independent
mass loss produces hot, helium-rich stars. Due to the well-understood metallicity
dependence on the radiation-driven winds of hot stars, a window of opportunity
would open below 0.2 Z⊙, where self-stripped helium-rich stars can exist without
dense Wolf-Rayet winds that absorb hard ionizing radiation.

text: The population of the little red dots (LRDs) may represent a key phase of
supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging
as a key component to explain the most striking properties of LRDs, such as strong
Balmer breaks and Balmer absorption, as well as the weak IR emission. To dissect
the structure of LRDs, we analyzed new deep JWST/NIRSpec PRISM and G395H spectra
of FRESCO-GN-9771, one of the most luminous known LRDs at z = 5.5. These spectra
reveal a strong Balmer break, broad Balmer lines, and very narrow [O III] emission.
We revealed a forest of optical [Fe II] lines, which we argue are emerging from
a dense (nH = 109 − 10 cm−3) warm layer with electron temperature Te ≈ 7000 K.
The broad wings of Hα and Hβ have an exponential profile due to electron scattering
in this same layer. The high Hα : Hβ : Hγ flux ratio of ≈10.4 : 1 : 0.14 is an
indicator of collisional excitation and resonant scattering dominating the Balmer
line emission. A narrow Hγ component, unseen in the other two Balmer lines due
to outshining by the broad components, could trace the ISM of a normal host galaxy
with a star formation rate of ∼5 M⊙ yr−1. The warm layer is mostly opaque to Balmer
transitions, producing a characteristic P Cygni profile in the line centers suggesting
outflowing motions. This same layer is responsible for shaping the Balmer break.
The broadband spectrum can be reasonably matched by a simple photoionized slab
model that dominates the λ > 1500 Å continuum and a low-mass (∼108 M⊙) galaxy
that could explain the narrow [O III], with only a subdominant contribution to
the UV continuum. Our findings indicate that Balmer lines are not directly tracing
the gas kinematics near the SMBH and that the BH mass scale is likely much lower
than virial indicators suggest.

text: Galaxies exhibit a tight correlation between their star formation rate (SFR)
and stellar mass over a wide redshift range known as the star-forming main sequence
(SFMS). With JWST, the SFMS can now be investigated at high redshifts down to
masses of ∼106 M⊙, using sensitive star formation rate tracers such as the Hα
emission, which allow us to probe the variability in the star formation histories.
We present inferences of the SFMS based on 316 Hα-selected galaxies at z ∼ 4 − 5
with log(M★/M⊙) = 6.4 − 10.6. These galaxies were identified behind the Abell
2744 lensing cluster with NIRCam grism spectroscopy from the survey All the Little
Things (ALT). At face value, our data suggest a shallow slope in the SFMS (SFR ∝ M★α,
with α = 0.45). After we corrected this for the Hα-flux limited nature of our
survey using a Bayesian framework, the slope steepened to α = 0.59+0.10−0.09,
whereas current data on their own are inconclusive on the mass dependence of the
scatter. These slopes differ significantly from the slope of ∼1 that is expected
from the observed evolution of the galaxy stellar mass function and from simulations.
When we fixed the slope to α = 1, we found evidence for a decreasing intrinsic
scatter with stellar mass (from ∼0.5 dex at M★ = 108 M⊙ to 0.4 dex at M★ = 1010
M⊙). This difference might be explained by a (combination of) luminosity-dependent
SFR(Hα) calibration, a population of (mini)-quenched low-mass galaxies, or underestimated
dust attenuation in high-mass galaxies. Future deep observations with different
facilities can quantify these processes, which will enable us to achieve better
insights into the variability of the star formation histories.

text: "1. Collective behaviours are a fascinating study area due to the emergent
properties that can only arise in groups of interacting individuals. However,
their quantitative study is often impaired by technical difficulties, creating
either low-quality and sparse data or impractical data amounts, particularly when
capturing large groups over long periods of time. Common challenges arise from
recording group members with as little obscuring of each other as possible, as
well as in generating manageable data amounts with as high as possible information
content.\r\n2. We here provide a multicomponent system that allows to record,
analyse and simulate the long-term spatiotemporal activity patterns of insect
collectives, especially ant colonies. Our Ant Observing System, ALTAA, comprises
a flat-nest design to prevent occlusion of individuals, a recording system running
on a low-power single-board-computer, and a set of computer programmes performing
quantitative analyses to guide the formation and validation of rules underlying
the observed collective patterns. Our system is scalable in that it allows parallel,
continuous observation of a high number of colonies using low memory space, with
colony maintenance requirements (e.g. feeding, nest humidity) being achieved at
lowest possible disturbance by the experimenter.\r\n3. We showcase the potential
of the system in a study using the black garden ant, Lasius niger, where we analyse
the spatiotemporal effects of different group sizes (1, 6, 10 ants), brood (larvae)
presence or absence, as well as of different nest geometries, over a period of
1 week. We show that the ants' motion activity has a weak periodicity in the range
of 20 to 120 min promoted by larval presence, and that ants are spatially attracted
to their larvae, the water source and the walls. We also find that the presence
of nestmates lowers an individual ant's motion activity. Observed data are compared
to simulations of the temporal activity of the ants.\r\n4. ALTAA provides a powerful
toolkit to quantify and interpret spatial and temporal collective activity patterns
in (social) insects over extended periods."

text: This study examines the distribution, growth, and GLOF hazard of glacial lakes
across major Himalayan river basins. Basin-wise GLOF susceptibility was assessed
using glacial lake abundance, spatial distribution, and rates of lake area expansion.
The Kosi, Yarlung Zangbo, Manas, and Upper Indus basins were identified as the
most susceptible and classified as critical. The highest rates of lake size increase
were observed in the Kosi Basin, followed by Yarlung Zangbo, Manas, Karnali, Upper
Indus, and Tista, indicating their potential as future GLOF-prone regions. Moreover,
a Himalayan-scale GLOF hazard map was generated integrating population, hydropower
infrastructure, potential flood volume, roads, settlements, and railways revealing
high hazard levels in the Chenab, Jhelum, Teesta, and Beas basins in India; the
Koshi, Tama-Koshi, and Dudh-Koshi basins in Nepal; and the Kuri Chu sub-basin
of the Manas Basin in Bhutan. These findings highlight priority regions where
detailed field investigations and hydrodynamic modelling are essential before
further infrastructure development.

text: "Terahertz (THz) spectroscopy is a powerful probe of low-energy excitations
in complex materials. Extending it into the nonlinear regime broadens its scope
and can provide valuable insight into interactions among these modes. However,
interpreting nonlinear spectra is challenging because resonant features in this
case do not always reflect intrinsic material dynamics. Here, we study nonlinear
THz-induced Kerr effect in a generic material LaAlO3. After detailed analysis
of temporal oscillations of the Kerr signal, we identify an \U0001D438\U0001D454
Raman mode at 1.1 THz excited through a two-photon process, while two additional
peaks (0.86 and 0.36 THz) arise from phase matching of the near-infrared probe
beam with co- and counterpropagating THz pump fields, mediated by off-resonant
electronic hyperpolarizability. These results demonstrate the crucial role of
kinematic effects in shaping THz-induced Kerr response and establish a framework
for interpreting nonlinear spectroscopies in complex materials."

text: Despite its pivotal role in optical manipulation, high capacity communications,
and quantum information, a general measure of orbital angular momentum (OAM) in
structured light remains elusive. In optical fields, where multiple vortices coexist,
the local nature of vortex OAM and the absence of a common rotation axis make
the total OAM of the field difficult to quantify. Here, we introduce the R index—a
metric that captures the intrinsic OAM content of any structured optical field,
from pure Laguerre–Gaussian modes to arbitrary multi vortex superpositions. Not
only does this metric quantify the total OAM, it also assesses field purity, providing
insight into the fidelity and robustness of the OAM generation. By unifying OAM
characterization into a single figure of merit, the R index enables direct comparison
across diverse beam profiles and facilitates the identification of optimal configurations
for both foundational studies and applied technologies.

text: We study the ground state energy of a gas of spin 1/2 fermions with repulsive
short-range interactions. We derive an upper bound that agrees, at low density
e, with the Huang–Yang conjecture. The latter captures the first three terms in
an asymptotic low-density expansion, and in particular the Huang–Yang correction
term of order e^7/3. Our trial state is constructed using an adaptation of the
bosonic Bogoliubov theory to the Fermi system, where the correlation structure
of fermionic particles is incorporated by quasi-bosonic Bogoliubov transformations.
In the latter, it is important to consider a modified zero-energy scattering equation
that takes into account the presence of the Fermi sea, in the spirit of the Bethe–Goldstone
equation.

text: Physical exercise acutely improves hippocampus-dependent memory. Whereas animal
studies have offered cellular- and synaptic-level accounts of these effects, human
neuroimaging studies show that exercise improves hippocampal-cortical connectivity
at the macroscale level. However, the neurophysiological basis of exercise-induced
effects on hippocampal-cortical circuits remains unknown. Experimental evidence
supports the idea that hippocampal sharp wave-ripples (SWR) play a critical role
in learning and memory. Coupling between SWRs in the hippocampus and neocortex
may reflect modulations in inter-regional connectivity required by mnemonic processes.
Here, we examine the hypothesis that exercise modulates hippocampal-cortical ripple
dynamics in the human brain. We performed intracranial recordings in epilepsy
patients undergoing pre-surgical evaluation, during awake resting state, before
and after an exercise session. Exercise increased ripple rate in the hippocampus.
Exercise also enhanced the coupling and phase-synchrony between cortical ripples
in the limbic and the default mode (DM) cortical networks and hippocampal SWRs.
Further, a higher heart rate during exercise, reflecting exercise intensity, was
related to a subsequent increase in resting state ripples across specific cortical
networks, including the DM network. These results offer the first direct evidence
that a single exercise session elicits changes in ripple events, a well-established
neurophysiological marker of mnemonic processing. The characterisation and anatomical
distribution of the described modulation points to hippocampal ripples as a potential
mechanism by which exercise elicits its reported short-term effects in cognition.
acknowledgement: We acknowledge the generosity of the patients, who contributed time
and effort to take part in this study.

text: We present and test a protocol to learn the matrix-product operator (MPO)
representation of an experimentally prepared quantum state. The protocol takes
as input classical shadows corresponding to local randomized measurements, and
outputs the tensors of an MPO maximizing a suitably defined fidelity with the
experimental state. The tensor optimization is carried out sequentially, similarly
to the well-known density matrix renormalization group algorithm. Our approach
is provably efficient under certain technical conditions expected to be met in
short-range correlated states and in typical noisy experimental settings. Under
the same conditions, we also provide an efficient scheme to estimate fidelities
between the learned and the experimental states. We experimentally demonstrate
our protocol by learning entangled quantum states of up to N = 96 qubits in a
superconducting quantum processor. Our method upgrades classical shadows to large-scale
quantum computation and simulation experiments.

text: 'The Hα emission line in galaxies is a powerful tracer of their recent star
formation activity. With the advent of JWST, we are now able to routinely observe
Hα in galaxies at high redshift (z ≳ 3) and thus measure their star formation
rates (SFRs). However, using classical SFR(Hα) calibrations to derive the SFRs
leads to biased results because high-redshift galaxies are commonly characterized
by low metallicities and bursty star formation histories, affecting the conversion
factor between the Hα luminosity (LHα) and the SFR. We developed a set of new
SFR(Hα) calibrations that allowed us to predict the SFRs of Hα-emitters at z ≳ 3
with very little error. We used the SPHINX cosmological simulations to select
a sample of star-forming galaxies representative of the Hα-emitter population
observed with JWST. We then derived linear corrections to the classical SFR(Hα)
calibrations that took variations in the physical properties (e.g., stellar metallicities)
among individual galaxies into account. We obtained two new SFR(Hα) calibrations
that compared to the classical calibrations reduce the root mean squared error
(RMSE) in the predicted SFRs by ΔRMSE ≈ 0.04 dex and ΔRMSE ≈ 0.06 dex, respectively.
Using the recent JWST NIRCam/grism observations of Hα-emitters at z ∼ 6, we show
that the new calibrations affect the high-redshift galaxy population statistics:
(i) the estimated cosmic SFR density decreases by ΔρSFR ≈ 12%, and (ii) the observed
slope of the star formation main sequence increases by Δ∂logSFR/∂logM★ = 0.08 ± 0.02.'

text: Controlling the size and shape of assembled structures is a fundamental challenge
in self-assembly and is highly relevant in material design and biology. Here,
we show that specific but promiscuous short-range binding interactions make it
possible to economically assemble linear filaments of user-defined length. Our
approach leads to independent control over the mean and width of the filament
size distribution and allows us to smoothly explore design trade-offs between
assembly quality (spread in size) and cost (number of particle species). We employ
a simple hierarchical assembly protocol to minimize assembly times and show that
multiple stages of hierarchy make it possible to extend our approach to the assembly
of higher-dimensional structures. Our work provides a conceptually simple solution
to size control that is applicable to a broad range of systems, from DNA nanoparticles
to supramolecular polymers and beyond.

text: 'Embryogenesis in the model plant Arabidopsis thaliana provides a framework
for understanding how cell polarity and patterning coordinate with hormonal signalling
to establish the plant body plan. Following fertilisation, the zygote divides
asymmetrically to generate apical and basal lineages, establishing the apical–basal
axis that defines future shoot and root poles. Genetic and molecular analyses
of classical mutants including gnom, monopteros (mp), bodenlos (bdl) and topless
revealed that localised auxin biosynthesis, directional transport and downstream
transcriptional responses are central to apical–basal axis establishment and organ
initiation. The main components of this regulation are polarly localised PIN auxin
transporters and downstream modules involving MONOPTEROS and WUSCHEL-RELATED HOMEOBOX
transcription factors. Advances in microscopy have transformed the study of Arabidopsis
embryogenesis: fluorescence-compatible clearing reagents and three-dimensional
reconstructions now permit quantitative analyses of cell geometry, division orientation,
and cytoskeletal dynamics. Live ovule imaging setups with confocal laser scanning
and multiphoton microscopes enable real-time observation of embryo development,
while laser-assisted cell ablation can be used to probe cell-to-cell communication
and fate plasticity. Together, these methodological breakthroughs position Arabidopsis
embryos as a prime model for dissecting the chemical and biophysical cues that
shape plant development.'

text: An individual's phenotype reflects a complex interplay of the direct effects
of their DNA, epigenetic modifications of their DNA induced by their parents,
and indirect effects of their parents' DNA. Here, we derive how the genetic variance
within a population is changed under the influence of indirect maternal, paternal
and parent-of-origin effects under random mating. We also consider indirect effects
of a sibling, in particular how the genetic variance is altered when looking at
the phenotypic difference between two siblings. The calculations are then extended
to include assortative mating (AM), which alters the variance by inducing increased
homozygosity and correlations within and across loci. AM likely leads to covariance
of parental genetic effects, a measure of the similarity of parents in the indirect
effects they have on their children. We propose that this assortment for parental
characteristics, where biological parents create similar environments for their
children, can create shared parental effects across traits and the appearance
of cross-trait AM. Our theory shows how the resemblance among relatives increases
under both AM, indirect and parent-of-origin effects. When our model is used to
predict correlations among relatives in human height, we find that explaining
the patterns observed in real data requires both indirect genetic effects and
assortative mating. The degree to which direct, indirect and epigenetic effects
shape the phenotypic variance of complex traits remains an open question that
requires large-scale family data to be resolved.

text: Insulating oxides are among the most abundant solid materials in the universe1,2,3.
Of the many ways in which they influence natural phenomena, perhaps the most consequential
is their capacity to transfer electrical charge during contact4,5,6,7,8,9,10—which
occurs even between samples of the same oxide—yet the symmetry-breaking parameter
that causes this remains unidentified11,12. Here we show that adventitious carbonaceous
molecules adsorbed from the environment are the symmetry-breaking factor in same-material
oxide contact electrification (CE). We use acoustic levitation to measure charge
exchange between a sphere and a plate composed of identical amorphous silicon
dioxide (SiO2). Although charging polarity is random for co-prepared samples,
we control it with baking or plasma treatment. Observing the charge-exchange relaxation
afterwards, we see dynamics over a timescale of hours and connect this directly
to the presence of adventitious carbon with time-of-flight mass spectrometry,
low-energy ion scattering and infrared spectroscopy. Going further, we confirm
that adventitious carbon can even determine charge exchange among different oxides.
Our results identify the symmetry-breaking parameter that causes insulating oxides
to exchange charge in settings ranging from desert sands4 to volcanic plumes5,6,
while simultaneously highlighting an overlooked factor in CE more broadly.

text: Sex-chromosome systems are highly variable across animals, but how they transition
from one to another is not well understood. Diptera have undergone multiple sex-chromosome
turnovers and expansions while maintaining their general chromosomal content,
which makes them an ideal clade to study such transitions. We analyzed more than
100 dipteran whole-genome assemblies and identified 4 new lineages that underwent
sex-chromosome turnover (in addition to the 5 previously reported). We find that
the majority of turnovers happened in the group Schizophora, which tend to have
fewer genes on Muller element F (the chromosome homologous to the ancestral insect
X chromosome) than lower dipterans, a factor previously hypothesized to facilitate
turnover. Most derived X chromosomes have higher GC content than autosomes, consistent
with a high prevalence of male achiasmy in Diptera. In addition, an excess of
gene movement out of the X is detected for most of these new X chromosomes, and
many of these moved genes have high testis expression in Drosophila, suggesting
that out-of-X gene movement contributes to the long-term demasculinization of
X chromosomes.

text: Human height is a model for the genetic analysis of complex traits, and recent
studies suggest the presence of thousands of common genetic variant associations
and hundreds of low-frequency/rare variants. Here, we develop a new algorithmic
paradigm based on approximate message passing (genomic vector approximate message
passing [gVAMP]) for identifying DNA sequence variants associated with complex
traits and common diseases in large-scale whole-genome sequencing (WGS) data.
We show that gVAMP accurately localizes associations to variants with the correct
frequency and position in the DNA, outperforming existing fine-mapping methods
in selecting the appropriate genetic variants within WGS data. We then apply gVAMP
to jointly model the relationship of tens of millions of WGS variants with human
height in hundreds of thousands of UK Biobank individuals. We identify 59 rare
variants and gene burden scores alongside many hundreds of DNA regions containing
common variant associations and show that understanding the genetic basis of complex
traits will require the joint analysis of hundreds of millions of variables measured
on millions of people. The polygenic risk scores obtained from gVAMP have high
accuracy (including a prediction accuracy of ∼46% for human height) and outperform
current methods for downstream tasks such as mixed linear model association testing
across 13 UK Biobank traits. In conclusion, gVAMP offers a scalable foundation
for a wider range of analyses in WGS data.

text: We study Kirillov algebras attached to minuscule highest weight representations
of semisimple Lie algebras. They can be viewed as equivariant cohomology algebras
of partial flag varieties. Real structures on the varieties then induce involutions
of these algebras. We describe how these involutions act on the spectra of minuscule
Kirillov algebras, and model the fixed points via the equivariant cohomology of
real partial flag varieties. We then use this model to characterise freeness of
the fixed point coordinate ring over the appropriate base. As an application,
we recover a q = -1 phenomenon of Stembridge in the minuscule case by geometric
means.

text: Auxin canalization is a self-organizing process that governs the flexible
formation of vasculature by reinforcing the formation of auxin transport channels.
A key prerequisite is the feedback between auxin signaling and directional auxin
transport, mediated by PIN transporters. Despite the developmental importance
of canalization, the molecular components linking auxin perception to the regulation
of PIN auxin transporters remain poorly understood. Here, we identify TOW, a novel
and essential component of auxin canalization that links intracellular auxin signaling
with cell surface auxin perception. TOW is regulated downstream of TIR1/AFB-Aux/IAA-WRKY23
transcriptional auxin signaling. tow mutants exhibit defects in regeneration and
de novo vasculature formation, along with impaired formation of polarized, PIN-expressing
auxin channels. At the subcellular level, these mutants display disrupted auxin-induced
PIN polarization and altered PIN endocytic trafficking dynamics. TOW localizes
predominantly to the plasma membrane, where it interacts with receptor-like kinases
involved in auxin canalization, including the TMK1 auxin co-receptor and the CAMEL-CANAR
complex. TOW promotes PIN interaction with these kinases and stabilizes PINs at
the cell surface. Together, our findings identify TOW as a molecular link between
intracellular and cell surface auxin signaling mechanisms that converge on PIN
trafficking and polarity, providing new insights into how auxin signaling regulates
directional auxin transport for the self-organizing formation of vasculature during
flexible plant development.
