text: 'The small DAHe and DAe spectral classes comprise isolated, hydrogen-dominated
atmosphere white dwarfs that exhibit variable photometric flux and Balmer line
emission. These mysterious systems offer unique insight into the complex interplay
between magnetic fields, stellar rotation and atmospheric activity in single white
dwarfs. DAHe stars have detectable magnetic fields through Zeeman-split spectral
lines, whereas DAe stars lack such splitting. We report the first discovery and
characterization of magnetism in the DAe white dwarf WD J165335.21−100116.33 with
new time-resolved spectropolarimetry from FORS2. We detect a weak but variable
longitudinal magnetic field with values Bz > −9.2 ± 2.4 kG and Bz < −2.2 ± 1.0
kG. Independent ZTF and ATLAS photometry reveal a consistent period of P = 80.3070
± 0.0007 h. Time-resolved optical spectroscopy obtained with six ground-based
instruments demonstrates strong modulation in the strength of the Hα and Hβ Balmer
line emission with P = 80.2922 ± 0.0108 h. The photometric flux and Balmer emission
strength vary in antiphase, with the strongest magnetic detections coinciding
with phases of low photometric flux and strong line emission. These characteristicssupport
the theory that a magnetically active, temperature-inverted spot/region is producing
an optically thin chromospheric emission region. Comparison with other DAe and
DAHe white dwarfsreveals all systems have a strikingly similar antiphase phenomenology,
reinforcing the theory that they are subject to a unified physical mechanism.
With the detection of a weak magnetic field, we reclassify WD J165335.21−100116.33
as a low-field DAHe white dwarf. '

text: The paraventricular hypothalamus (PVH) controls behavioral and physiologic
processes, including appetite, social behavior, autonomic outflow, and pituitary
hormone secretion. However, molecular markers for centrally projecting PVH neuron
populations remain largely undefined, and a complete census of PVH cell types
has not been established. Therefore, we performed extensive single-cell/nucleus
RNA sequencing to catalog PVH neuron subtypes and multiplexed error-robust fluorescence
in situ hybridization (MERFISH) to map them spatially. Our spatial transcriptomic
atlas resolves 26 Sim1+ and 29 GABAergic neuron populations from the PVH and surrounding
areas. Additionally, projection-based profiling identified neurons that project
to the parabrachial region (PB) and spinal cord, helping to determine PVH populations
that regulate satiety and sympathetic nervous system activity, respectively. Notably,
activation of PB-projecting PVH neurons expressing Brs3 reduces food intake, and
silencing them causes obesity. Together, this atlas contributes high-resolution
PVH spatial and circuit-based gene expression profiles, representing a valuable
resource for the field of homeostasis.

text: "We develop a new algorithmic framework for designing approximation algorithms
for cut-based optimization problems on capacitated undirected graphs that undergo
edge insertions and deletions. Specifically, our framework dynamically maintains
a variant of the hierarchical \U0001D457-tree decomposition of [Madry FOCS’10],
achieving a poly-logarithmic approximation factor to the graph’s cut structure
and supporting edge updates in \U0001D442(\U0001D45B\U0001D700) amortized update
time, for any arbitrarily small constant \U0001D700 ∈(0,1).\r\nConsequently, we
obtain new trade-offs between approximation and update/query time for fundamental
cut-based optimization problems in the fully dynamic setting, including all-pairs
minimum cuts, sparsest cut, multi-way cut, and multi-cut. For the last three problems,
these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic
approximation in sub-linear time per operation.\r\nThe main technical ingredient
behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle
vertex splits with low recourse. This is achieved by white-boxing the dynamic
cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing,
together with new structural insights about the maintenance of these forests under
vertex splits. Given the versatility of cut sparsification in both the static
and dynamic graph algorithms literature, we believe this construction may be of
independent interest."

text: Robust Markov Decision Processes (RMDPs) generalize classical MDPs that consider
uncertainties in transition probabilities by defining a set of possible transition
functions. An objective is a set of runs (or infinite trajectories) of the RMDP,
and the value for an objective is the maximal probability that the agent can guarantee
against the adversarial environment. We consider (a) reachability objectives,
where given a target set of states, the goal is to eventually arrive at one of
them; and (b) parity objectives, which are a canonical representation for ω-regular
objectives. The qualitative analysis problem asks whether the objective can be
ensured with probability 1. In this work, we study the qualitative problem for
reachability and parity objectives on RMDPs without making any assumption over
the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are
twofold. We first present efficient algorithms with oracle access to uncertainty
sets that solve qualitative problems of reachability and parity objectives. We
then report experimental results demonstrating the effectiveness of our oracle-based
approach on classical RMDP examples from the literature scaling up to thousands
of states.

text: "We present an exact fully-dynamic minimum cut algorithm that runs in \U0001D45B\U0001D45C(1)
deterministic update time when the minimum cut size is at most 2Θ(log3/4−\U0001D450\U0001D45B)
for any \U0001D450 >0, improving on the previous algorithm of Jin, Sun, and Thorup
(SODA 2024) whose minimum cut size limit is (log\U0001D45B)\U0001D45C(1). Combined
with graph sparsification, we obtain the first (1 +\U0001D716)-approximate fully-dynamic
minimum cut algorithm on weighted graphs, for any \U0001D716 ≥2−Θ(log3/4−\U0001D450\U0001D45B),
in \U0001D45B\U0001D45C(1) randomized update time.\r\nOur main technical contribution
is a deterministic local minimum cut algorithm, which replaces the randomized
LocalKCut procedure from El-Hayek, Henzinger, and Li (SODA 2025)."

text: 'Recent research in nanophotonics for scintillation-based imaging has demonstrated
promising improvements in scintillator performance. In parallel, advances in nanophotonics
have enabled wavefront control through metasurfaces, a capability that has transformed
fields such as microscopy by allowing tailored control of optical propagation.
This naturally raises the following question, which we address in this Perspective:
can wavefront-control strategies be leveraged to improve scintillation-based imaging?
To answer this question, we explore nanophotonic- and metasurface-enabled wavefront
control in scintillators to mitigate image blurring arising from their intrinsically
diffuse light emission. While depth-of-field extension in scintillation faces
fundamental limitations absent in microscopy, this approach reveals promising
avenues, including stacked scintillators, selective spatial-frequency enhancement,
and X-ray energy-dependent imaging. These results clarify the key distinctions
in adapting wavefront engineering to scintillation and its potential to enable
tailored detection strategies.'

text: Cells are defined by lipid membranes that differ in their structure across
the tree of life. While the membranes of most bacteria and eukaryotes consist
of single-headed bilayer lipids, the membranes of archaea are composed of mixtures
of single-headed bilayer lipids and double-headed bolalipids. Archaeal bolalipids
can adopt straight or u-shaped conformations, enabling them—together with bilayer
lipids—to control whether membranes form bilayer or monolayer structures. Yet,
the physical principles governing archaeal membranes remain largely unexplored,
especially how membrane structure couples to externally imposed curvature during
membrane remodeling. Here, we perform coarse-grained molecular dynamics simulations
of toroidal vesicles to systematically probe the effects of all relevant combinations
of mean and Gaussian curvatures on shape stability and lipid organization. We
find that soft bilayer membranes can sustain all curvatures induced, whereas rigid
bolalipid monolayer membranes either transition to different vesicle shapes or
rupture. Bilayer-mimicking u-shaped bolalipids and bilayer lipids are spatially
accumulated in regions of high mean membrane curvature independent of Gaussian
curvature. Our work identifies curvature–composition coupling as a physical signature
of archaeal membrane remodeling.

text: Entanglement does not always require one particle per party. It was predicted
some 30 years ago that a single photon traversing a beam splitter could violate
a Bell inequality. Although initially debated, single-photon nonlocality was eventually
demonstrated via homodyne measurements. Here, we present an alternate realization
that avoids the complexity of homodyne measurements and potential loopholes in
their implementation. We violate a Bell inequality by performing joint measurements
on two copies of the same single-photon entangled state, where one photon acts
as a phase reference for the other, making it self-referential. We observe CHSH
parameters of 2.71 = 0.09 and 2.23 = 0.07, depending on the joint measurements
implemented. This offers a perspective on single-photon nonlocality and a more
accessible experimental route, potentially applicable to general mode-entangled
states in diverse platforms.

text: 'Phase singularities—points carrying quantized topological charge—are universal
features found across diverse wave systems from superfluids and superconductors
to acoustic and optical fields1,2,3,4. Ensembles of these singularities exhibit
distance correlations resembling particles in liquids5,6,7,8, extensively studied
for their role in exotic material phases9,10,11. By contrast, the full correlations
in phase space that govern the system evolution have remained unexplored and experimentally
inaccessible. Here we directly measure the ultrafast dynamics of optical singularity
ensembles, capturing their full phase-space correlations, presenting the joint
distance–velocity distribution. Our observations show a breakdown of the particle-singularity
analogy12: phase singularities accelerate towards formally divergent velocities
in the moment before annihilation7,13,14, indicated by measurements of velocities
exceeding the speed of light. These apparent superluminal velocities are paradoxically
amplified by the slow group velocity of hyperbolic phonon polaritons in our material
platform, hexagonal boron nitride membranes15,16,17,18,19. We demonstrate these
phenomena using combined hardware and algorithmic advances in ultrafast electron
microscopy18,20,21,22,23,24,25, achieving spatial and temporal resolutions, each
an order of magnitude below the polaritonic wavelength and cycle period. Our findings
deepen our understanding of phase singularities and their universality, enabling
to probe topological defect dynamics at previously unattainable timescales.'

text: Liquid-like superionic conductors, with highly mobile ions in a rigid framework,
offer intrinsically low lattice thermal conductivity without compromising electronic
transport. Argyrodite-type Ag8SnSe6 exhibits a melt-like Ag sublattice that drives
lattice thermal conductivity (κL) below 0.2 watts per meter per kelvin, yet its
low carrier concentration limits the power factor. Here, interstitial Ag atoms
raise the Fermi level into the conduction band, substantially increasing the electron
concentration. Simultaneously, the formation of a secondary Ag2Se phase generates
lattice distortions that enhance phonon scattering. A pronounced mismatch between
electronic (~200 nanometers) and phononic (~0.22 nanometers) mean free paths decouples
charge and heat transport, enabling concurrent suppression of κL and retention
of high electrical conductivity. This coupled electronic-phononic modulation yields
a record ZT of 0.72 at ambient temperature and a peak ZT of 1.1 at 735 kelvins,
with an average ZTavg of 0.72 over 320 to 735 kelvins. A unicouple device achieves
6.3% efficiency under a 357-kelvin gradient, highlighting a practical strategy
for high-performance midtemperature thermoelectrics.

recipe and show how to control their (equivariant) truncating invariants. Consequently,
we prove that on simple varieties: (i) if k = k and char k = p, the p-adic cyclotomic
trace is an equivalence; (ii) if k = Q, the Goodwillie–Jones trace is an isomorphism
in degree zero; (iii) we can control homotopy invariant K-theory KH, which is
equivariantly formal and determined by its topological counterparts. Simple varieties
are quite special, but encompass important singular examples appearing in geometric
representation theory. We, in particular, show that both finite and affine Schubert
varieties for GLn lie in this class, so all the above results hold for them. '

text: The collagen triple helix assembles hierarchically into bundled oligomers,
solvated networks, and fibers. Synthetic peptide assemblies, driven by supramolecular
interactions, can form single triple helices through intrahelical amino acid pairs;
however, the principles guiding interhelical associations into higher-order structures
remain unclear. Here, we incorporate cation−π and electrostatic charge pairs to
probe interhelical interactions and elucidate the mechanisms driving triple helix
assembly into fibrils, nanotubes, and nanosheets. Introducing cation−π pairs into
a fibrillating collagen mimetic resulted in D-periodic fibrils with pH-sensitive
gelation. By alternating the presentation of electrostatic and cation−π pairs,
the assembly of another D-periodic fibril featuring inner and outer triple-helical
layers was resolved by cryo electron microscopy to a resolution of 8 Å. At physiological
pH, antiparallel association of these triple helices leads to the formation of
nanotubes. The packing behavior of triple helices correlates with the interhelical
interactions, where parallel associations favor fibril formation and antiparallel
interactions drive nanotube and nanosheet assembly. These self-assembling triple-helical
peptides demonstrate how packing of higher-order structures can be tailored with
supramolecular interactions and establish the relationship of different hierarchical
collagen-mimetic assemblies as pH-dependent.

text: Reactive oxygen species (ROS) have been implicated in multiple signaling processes
in plants, but the underlying mechanisms and roles remain enigmatic. In this study,
we developed a method of live imaging of apoplastic ROS at the root surface. Distinct
signals, including auxin, extracellular adenosine triphosphate, and rapid alkalinization
factor 1 peptide, induce cytosolic calcium transients and apoplastic ROS bursts.
Genetic and optogenetic manipulations of Arabidopsis identified calcium transients
as necessary and sufficient for ROS bursts through activation of reduced nicotinamide
adenine dinucleotide phosphate (NADPH) oxidases RBOHC and RBOHF. Apoplastic ROS
bursts are not required, but they do limit gravity-induced root bending. Root
bending is sensed by the stretch-activated calcium channel MCA1, leading to NADPH
oxidase activation. The resulting ROS production stiffens cell walls to facilitate
soil penetration. Apoplastic ROS thus provides a means to balance tissue flexibility
and stiffness to navigate soil.

text: The advantageous characteristics attributed to the 19F nucleus have made it
a popular target for nuclear magnetic resonance (NMR) once again in recent years.
Aside from solution NMR, an increasing number of studies have been conducted applying
solid-state magic-angle spinning (MAS) NMR to fluorine-labelled samples. Here,
the high chemical shift anisotropy and strong dipolar couplings can be utilised
to get structural insights into proteins and measure long distances. Despite increasing
popularity and promising benefits, the sensitivity of biomolecular 19F MAS NMR
often suffers from slow longitudinal T1 relaxation and therefore long recycle
delays. In this work, we expand paramagnetic doping, an approach commonly used
to reduce proton T1 relaxation times, to 19F-labelled biological samples. We study
the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F T1 and T2, and 13C T1 and T2 relaxation
in a [5-19F13C]-tryptophan-labelled protein via 19F-detected MAS NMR experiments.
The observed paramagnetic relaxation enhancement substantially reduces measurement
times of 19F MAS NMR experiments without compromising resolution. Additionally,
we report the chemical shift assignments of all four fluorotryptophan signals
in the 12×39 kDa-large protein TET2 using a mutagenesis approach.

text: It is predicted that half or more of all cataclysmic variables (CVs) should
have evolved past the period minimum and now exist as so-called period bouncers
where a white dwarf should be accreting from a Roche lobe filling substellar companion.
However, this prediction stands in stark contrast to observations, where only
a few per cent of CVs are found in this evolutionary phase. A potential solution
to this discrepancy is that a magnetic field emerges from within the white dwarf
after the system has reached the period minimum. The transfer of angular momentum
from the spin of the white dwarf into the orbit then pushes the two stars apart,
detaching them for potentially billions of years. Here we present the discovery
of ZTF J021804.16+071152.93, a detached 0.69 +- 0.01 M, 19 MG magnetic white
dwarf plus 37 +- 5MJup brown dwarf binary with an orbital period of 1.7 h. The
kinematics of the system indicate that it is a high probability member of the
Galactic thick disc. However, this strongly disagrees with the much younger age
of the system obtained from the white dwarf parameters, implying that the system
may have been accreting in the past. This system is therefore consistent with
having detached as a result of the emergence of the magnetic field of the white
dwarf when the system was still mass transferring, and may represent the ultimate
fate for many (perhaps even most) CVs.

text: Acidomycin is an anti-mycobacterial antibiotic with a unique mode of action,
targeting the biotin biosynthesis pathway. Despite being highly active against
mycobacteria in vitro, its development as an anti-tubercular agent has been hindered
due to suboptimal pharmacokinetics. Engineering of the acidomycin biosynthesis
may yield new analogues with improved pharmacological properties. Here, we describe
the identification of the acidomycin biosynthetic gene cluster (BGC) in a Streptomyces
bacterium isolated from the rhizosphere of Edelweiss. Notably, the acidomycin
BGC is located in proximity to the genes for the biosynthesis of stravidins, secondary
metabolites targeting a different enzyme in the biotin biosynthesis pathway, and
two genes for streptavidins, proteins that strongly bind and sequester biotin.
The identity of the acidomycin BGC was confirmed via both gene knock-out and heterologous
expression, which suggested that the fatty acid required for the formation of
acidomycin's acyl chain is most likely scavenged from the biotin biosynthesis
pathway. CRISPR/Cas9-assisted knock-out of the cytochrome P450-encoding gene in
the acidomycin BGC resulted in a significant decrease in its yield but did not
abrogate the biosynthesis completely.

text: Pyridyl motifs equipped with N-substituents can be powerful ligands for catalysis,
yet their broader adoption is limited by the lack of a practical method to prepare
these scaffolds. We report a modular, robust, and versatile Buchwald–Hartwig amination
protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine,
and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N-substituents.
These conditions streamline ligand library synthesis and will facilitate systematic
studies in catalysis and related applications.

text: "Given a set A of n points (vertices) in general position in the plane, the
complete geometric graph \r\nKn[A] consists of all (n2) segments (edges) between
the elements of A. It is known that the edge set of every complete geometric graph
on n vertices can be partitioned into O(n3∕2) crossing-free paths (or matchings).
We strengthen this result under various additional assumptions on the point set.
In particular, we prove that for a set A of n randomly selected points, uniformly
distributed in [0,1]2, with probability tending to 1 as n→∞, the edge set of Kn[A]
can be covered by O(nlogn) crossing-free paths and by O(n√logn) crossing-free
matchings. On the other hand, we construct n-element point sets such that covering
the edge set of Kn[A] requires a quadratic number of monotone paths."

text: The origin(s) of life (OoL), which has puzzled scientists for centuries, remains
a major scientific challenge in the 21st century. Understanding the processes
relevant to the OoL demands theoretical frameworks that can connect processes
across scales, from microscopic dynamics to emergent levels of organization. While
experimental studies generate a wealth of data, theoretical and computational
approaches provide the structure necessary to interpret and generalize these findings.
In Part 1, we examined the most widely used experimental techniques in the field.
Here, we focus on the mathematical, physical, and computational techniques used
to model phenomena relevant to life’s origin(s). We discuss methods ranging from
quantum chemistry and molecular dynamics to chemical reaction networks, autocatalysis,
and evolutionary modeling, as well as information-theoretic and phylogenetic approaches
that link chemical and biological organization. We further highlight emerging
trends such as synthetic biology, omics-based methods, and laboratory automation
as novel points of contact for theory-experiment integration. Ultimately, we aim
to provide an educational tool that can facilitate more post-disciplinary collaborations
in OoL research by helping scientists understand what they can do about the problem
of life’s origins, rather than telling them how to think about it.
acknowledgement: This work is a collaborative effort of the titled authors as part
of the Origin of Life Early Career Network (OoLEN). We chose to add OoLEN as the
first author to give a better representation of this team effort, rather than listing
any single author as the first author. We hope such a thing can be adopted by others.
We indicate that authors 2–9 (S.A., C.B., C. Blanco, D.B., A.C.-R., C.M., O.M.,
Z.P., and A.V.D.) have made a more distinct contribution. All authors are listed
alphabetically by their last names. We would like to acknowledge all current and
past members of OoLEN for their contributions to our community. In particular, we
would like to acknowledge Evrim Fer, who helped with molecular phylogenetics. We
would like to thank the anonymous referees for reviewing Parts 1 and 2 of this manuscript;
this work was significantly improved through their feedback. S.A. acknowledges support
