text: Topological simplification is the process of reducing complexity of a function
while maintaining its essential features. Its goal is to find a new filter function,
which reorders cells of the input complex in a way which eliminates some persistent
homological features, without affecting the rest. We present a new approach to
simplification based on the concept of forbidden regions and combinatorial dynamics.
It allows us to reorder and cancel critical values, whose cancellation is not
possible using existing methods because they are not consecutive in the total
order. Each such cancellation takes O(c⋅n) time in the worst case, where c is
the number of birth-death pairs and n is the size of the input complex.

text: In this issue of Cell Host & Microbe, Osterman et al. discover aRES,1 a new
family of bacterial immune proteins that deplete cellular NAD+, generating cleavage
products that cannot be utilized by canonical phage NAD+ regeneration pathways.
They identify the invader-specific trigger for aRES and characterize two distinct
evolutionary countermeasures employed by phages to resist aRES.

text: "Blockchains enable distributed consensus in permissionless settings, where
participants\r\nare unknown, dynamically changing, and do not trust each other.
While Bitcoin,\r\nbased on Proof-of-Work (PoW), was the first protocol in this
model, significant\r\nresearch has focused on permissionless protocols using alternative
physical resources,\r\nspecifically Proof-of-Space (PoSpace) and Verifiable Delay
Functions (VDFs). This\r\nthesis investigates the theoretical limits and design
space of longest-chain protocols in\r\nthe fully permissionless and dynamically
available settings using these three resources.\r\nFirst, we address the feasibility
of blockchains relying solely on storage as a resource.\r\nWe prove a fundamental
impossibility result: there exists no secure longest-chain\r\nprotocol based exclusively
on Proof-of-Space in the fully permissionless or dynamically\r\navailable settings.
Further, we quantify the adversarial capabilities required to execute\r\na double-spend
attack. Our result formally justifies the necessity of coupling PoSpace\r\nwith
time-dependent primitives (such as VDFs) or to move to less permissive settings\r\n(quasi-permissionless
or permissioned) to ensure security.\r\nSecond, we generalize Nakamoto-like heaviest
chain consensus to protocols utilizing\r\ncombinations of multiple physical resources.
We analyze chain selection rules governed\r\nby a weight function Γ(S, V,W), which
assigns weight to blocks based on recorded\r\nSpace (S), VDF speed (V ), and Work
(W). We provide a complete classification\r\nof secure weight functions, proving
that a weight function is secure against private\r\ndouble-spend attacks if and
only if it is homogeneous in the timed resources (V,W)\r\nand sub-homogeneous
in S. This framework unifies existing protocols like Bitcoin and\r\nChia under
a single theoretical model and provides a powerful tool for designing new\r\nlongest-chain
blockchains from a mix of physical resources."

text: We compare three global kilometer-scale models (ICON, IFS and NICAM) to clarify
the advantages and challenges of high-resolution global weather and climate modeling,
using different approaches to represent convection, from fully parameterized to
fully explicit. Our analysis focuses on tropical precipitation characteristics
spanning a wide range of spatio-temporal scales—including the diurnal cycle, extreme
precipitation, convective organization, and the Madden-Julian Oscillation (MJO)—along
with interactions between convection and the thermodynamic environment. All three
models commonly show weaker convective organization with smaller precipitation
cells than observed, though the strength of the bias varies by model. This diversity
is introduced by differences in the representation of (a) convective initiation
affected by the convective sensitivity to moisture and (b) tropospheric moistening
associated with deep convection. Models with stronger thermodynamic-convection
coupling increase environmental moisture near convection, thereby enhancing convective
organization. This has important upscale effects on the MJO; while IFS and NICAM
capture its eastward propagation well, ICON has difficulty reproducing it. The
amplitudes and phases of precipitation diurnal cycles over land show much greater
disagreement among the models than over ocean, influenced by how convection is
initiated. Biases in rain evaporation and cold pool formation hinder the propagation
of mesoscale convection, leading to errors such as the misrepresentation of nocturnal
convection moving off the coast of Sumatra in IFS and ICON. These results highlight
the importance of thermodynamic-convection coupling in realistically simulating
tropical convection across scales. To improve this coupling, kilometer-scale models
require better representation of the interaction between resolved convection and
three-dimensional turbulent mixing.

text: Dipolar (ℓ = 1) mixed modes have revealed a surprisingly weak differential
rotation between the core and the envelope of evolved solar-like stars. Quadrupolar
(ℓ = 2) mixed modes also contain information regarding internal dynamics but are
very rarely characterised due to their low amplitude and the challenging identification
of adjacent or overlapping rotationally split multiplets affected by near-degeneracy
effects. We aim to extend the broadly used asymptotic seismic diagnostics beyond
ℓ = 1 mixed modes by developing an analogue asymptotic description of ℓ = 2 mixed
modes while explicitly accounting for near-degeneracy effects that distort their
rotational multiplets. We have derived a new asymptotic formulation of near-degenerate
mixed ℓ = 2 modes that describes off-diagonal terms representing the interaction
between modes of adjacent radial orders. This formalism, expressed directly in
the mixed-mode basis, provides analytical expressions for the near-degeneracy
effects. We implemented the formalism within a global Bayesian mode-fitting framework
for a direct fit of all ℓ = 0, 1, 2 modes in the power spectrum density. We were
able to asymptotically model the asymmetric rotational splitting present in various
radial orders of ℓ = 2 modes observed in young red giant stars without the need
for any numerical stellar modelling. We applied our formalism to the Kepler target
KIC 7341231, and it yielded core and envelope rotation rates consistent with previous
numerical modelling while providing improved constraints from the global and model-independent
approach. We also characterised the new target, KIC 8179973, measuring its rotation
rate and mixed-mode parameters for the first time. As our framework relies on
a direct global fit, it allows for much better precision on the asteroseismic
parameters and rotation rate estimates than standard methods, yielding better
constraints for rotation inversions. We have placed the first observational constraints
on the asymptotic ℓ = 2 mixed-mode parameters (ΔΠ2, q2, and εg, 2), thus paving
the way towards the use of asymptotic seismology beyond ℓ = 1 mixed modes.

text: The recent detection of solar equatorial Rossby waves has renewed interest
in the study of gravito-inertial waves propagating in the convective envelope
of solar-type stars. In particular, the ability of these envelope gravito-inertial
modes to couple with those trapped in the radiative interior could open up new
opportunities for probing the deep-layer dynamics of solar-type stars. The possibility
for such a coupling to occur is particularly favoured among pre-main-sequence
(PMS) solar-type stars. Indeed, due to the contraction of the protostellar object,
they are able to reach high rotation frequencies before nuclear reactions are
ignited and magnetic braking becomes the driving mechanism for their rotational
evolution. In this work, we studied the coupling between the envelope inertial
waves and the radiative interior g modes in PMS stars, focussing on the case of
prograde dipolar modes. We considered the cases of 0.5 M⊙ and 1 M⊙ PMS models,
each with three different scenarios of rotational evolution. We show that for
stars that have formed with a sufficient amount of angular momentum, this coupling
can occur in frequency ranges that are accessible to space-borne photometry, creating
inertial dips in the period spacing pattern. Using an asymptotic analysis, we
characterised the shape of these inertial dips to show that they depend on rotation
and on the stiffness of the convective-radiative interface.

text: Kapitza-Dirac scattering, the diffraction of matter waves from a standing
light field, is widely utilized in ultracold gases, but its behavior in the strongly
interacting regime is an open question. Here, we develop a numerically exact two-body
description of Kapitza-Dirac scattering for two contact-interacting atoms in a
one-dimensional harmonic trap subjected to a pulsed optical lattice, enabling
us to obtain the numerically exact dynamics. We map how interaction strength,
lattice depth, lattice wave number, and pulse duration reshape the diffraction
pattern, leading to an interaction-dependent population redistribution in real
and momentum space. By comparing the exact dynamics to an impulsive sudden-approximation
description, we delineate the parameter regimes where it remains accurate and
those, notably at strong attraction and small lattice wave number, where it fails.
Our results provide a controlled few-body benchmark for interacting Kapitza-Dirac
scattering and quantitative guidance for Kapitza-Dirac-based probes of ultracold
atomic systems.

text: Model checking undiscounted reachability and expected-reward properties on
Markov decision processes (MDPs) are key for the verification of systems that
act under uncertainty. Popular algorithms are policy iteration and variants of
value iteration; in tool competitions, most participants rely on the latter. These
algorithms generally need worst-case exponential time. However, the problem can
equally be formulated as a linear programme, solvable in polynomial time. In this
paper, we give a detailed overview of today’s state-of-the-art algorithms for
MDP model checking with a focus on performance and correctness. We highlight their
fundamental differences, and describe various optimizations and implementation
variants. We experimentally compare floating-point and exact-arithmetic implementations
of all algorithms on three benchmark sets using two probabilistic model checkers.
Our results show that (optimistic) value iteration is a sensible default, but
other algorithms are preferable in specific settings. This paper thereby provides
a guide for MDP verification practitioners—tool builders and users alike.

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: We provide a theoretical framework to describe the dynamics of a free-electron
beam interacting with quantized bound systems in arbitrary electromagnetic environments.
This expands the quantum optics toolbox to incorporate free-electron beams for
applications in highly tunable quantum control, imaging, and spectroscopy at the
nanoscale. The framework recovers previously studied results and shows that electromagnetic
environments can amplify the intrinsically weak coupling between a free-electron
and a bound electron to reach previously inaccessible interaction regimes. We
leverage this enhanced coupling for experimentally feasible protocols in coherent
qubit control and towards the nondestructive readout and projective control of
the electron beam's quantum-number statistics. Our framework is broadly applicable
to microwave-frequency qubits, optical nanophotonics, cavity quantum electrodynamics,
and emerging platforms at the interface of electron microscopy and quantum information.

text: Polarization-resolved control and measurement of the optical field are essential
for a wide range of photonic systems, including coherent communication, polarimetric
sensing, and quantum information processing. We present a photonic integrated
circuit that enables the generation and analysis of arbitrary polarization states.
The device provides reconfigurable access to the full polarization degree of freedom
of coherent light within a single integrated platform. We experimentally demonstrate
arbitrary polarization state generation spanning the Poincare sphere, as well
as Stokes vector measurement on chip. Unlike conventional Stokes measurements
that rely on direct detection, polarization analysis utilizing this architecture
is intrinsically non-destructive, preserving the optical signal for further optical
domain processing. The devices are fabricated in a commercial foundry using CMOS-compatible
processes, enabling scalable and reproducible integration. By combining polarization
generation and analysis in a compact and stable photonic circuit, this work eliminates
the need for external polarization optics and provides a foundation for robust,
polarization-enabled photonic integrated systems.

text: Altermagnetism has recently emerged as a distinct class of collinear antiferromagnets
that break time-reversal symmetry, exhibiting a host of novel properties. Applied
strain has attracted particular attention as a key tuning parameter for altermagnets.
Although several experimental studies have demonstrated the preparation of single-domain
states through a combination of applied strain and magnetic field, the route to
such states remains unclear. Here, we use magneto-optical measurements on single
crystals of MnTe under applied strain to show that, in contrast to previous reports,
strain acts primarily to rotate the Néel vector L continuously. Since the orientation
of L determines the magnetic point group symmetry, this continuous rotation effectively
tunes the symmetry and its associated physical properties. Furthermore, we demonstrate
that built-in strain in free-standing crystals is sufficient to pin L into continuous
textures over millimeter length scales. Together, these results provide guidance
for future device design and open the door to leveraging the Néel vector orientation
as a tunable degree of freedom in spintronic applications.

text: How functional protein sequences are distributed in sequence space is fundamentally
important for evolutionary theory and protein design, particularly if a large
diversity of protein functions are hidden in evolutionarily unexplored areas of
the sequence space. However, this question is understudied in part because experimental
and computational studies use extant sequences as a starting point to study sequence
space. Here, we study whether extant sequences are representative of the entire
functional sequence space. Across thousands of protein families from vertebrates
and bacteria we calculate the dimensionality and the volume of sequence space
occupied by extant homologs. We find that the observed dimensionality and volume
of extant sequence space are minuscule, many orders of magnitude smaller than
what we estimated using a model of protein evolution. Simulating sequence evolution
we then quantify the impact of phylogeny, selection, and epistasis on restricting
the evolutionary exploration of sequence space. We find that sequence evolution
from a single common ancestor, or a single point of origin in sequence space,
is by far the largest limiting factor that reduces the dimensionality and volume
of extant sequence space. These results indicate that there are vast areas of
functional sequence space that have not been explored in evolution because of
the excessive restrictions on natural exploration of the protein sequence space
imposed by the point of origin effect. We suggest that protein design methods
that rely on extant sequences may be limited in their ability to discover truly
novel functions.

text: "We report the discovery of ATLAS J101342.5−451656.8 (hereafter ATLAS J1013−4516),
an 8.56 minute orbital-period mass-transferring AM Canum Venaticorum (AM CVn)
binary with a mean Gaia magnitude of G = 19.51, identified via periodic variability
in light curves from the Asteroid Terrestrial-impact Last Alert System (ATLAS)
of Gaia white dwarf candidates. Follow-up with the Large Lenslet Array Magellan
Spectrograph shows a helium-dominated accretion disk, and high-speed ULTRACAM
photometry reveals pronounced primary and secondary eclipses. We construct a decade-long
timing baseline leveraging light curves from the ATLAS and Gaia surveys, as well
as the high-speed imagers ULTRACAM on the New Energy Telescope and proto-Lightspeed
on the Magellan Clay telescope. From this timing baseline, we measure an orbital
period derivative of P 1.60 0.07 10 = ± × 12 s s−1. Interpreted in the context
of stable mass transfer, the magnitude and sign of P indicate that the orbital
evolution is governed by the interplay between gravitationalwave-driven angular-momentum
losses and mass transfer, directly probing the donor’s structural response to
mass loss. We constrain the accretor and donor mass based on stable mass-transfer
arguments assuming angularmomentum loss dominated by gravitational-wave emission,
allowing us to infer the characteristic gravitational\r\nwave strain of the binary
for future space-based GW observatories such as the Laser Interferometer Space
Antenna (LISA). We predict a characteristic strain corresponding to a 4 yr LISA
signal-to-noise ratio ≳10, establishing ATLAS J1013−4516 as a strong prospective
LISA source that will probe long-term orbital evolution in the mass-transferring
regime."

text: Structural and functional differences between brain hemispheres are a common
feature of animal nervous systems with reduced bilateral asymmetry often linked
to impaired cognitive performance. How neuronal left-right asymmetry is initiated
and integrated into a bilaterally symmetrical ground pattern is poorly understood.
Here, we show that the directional asymmetry of a Drosophila central brain circuit
originates from axonal interactions of two types of bilateral pioneer neurons.
Subsequent recruitment of neighboring neurons into the asymmetric neuropil primordium
results in hemisphere-specific microcircuits. Circuit lateralization requires
dynamic expression of the cell adhesion molecule Fasciclin 2 to maintain structural
plasticity in axonal remodeling. Reduced circuit asymmetry following cell type–specific
Fasciclin 2 manipulation affects adult brain function. These results reveal an
unexpected degree of developmental plasticity of late-born Drosophila neurons
in the formation of a circuit node via the lateralized recruitment of symmetric
circuit components.

text: On October 4, 2023, a proglacial lake named the South Lhonak lake was the
source of a catastrophic Glacier Lake Outburst Flood (GLOF) in the Teesta river
basin area, resulting in 24 fatalities and leaving over 70 persons missing. The
GLOF also destroyed 13 bridges and a major hydropower plant in the Chungthang
region. Over 60,000 individuals in four districts of Sikkim were impacted by this
GLOF event. This study examines the factors that led to the GLOF event. Our study
shows that the cause of this GLOF was initiated by a landslide, that dumped a
substantial amount (~ 38.31 million m3) of debris into the South Lhonak Lake.
Furthermore, the glacier that was connected to the lake, lost a big chunk of ice
mass (~ 7 million m3) due to calving. The combination of these two processes led
to the collapse of the left lateral moraine that consequently generated flood
waves which breached the terminal moraine dam of the lake. We recommend monitoring
land subsidence and calving events for large proglacial lakes to prevent the disastrous
consequences of such GLOFs in the future.

text: 'JWST’s “little red dots” (LRDs) are increasingly interpreted as active galactic
nuclei (AGN) obscured by dense thermalized gas rather than dust as evidenced by
their X-ray weakness, blackbody-like continua, and Balmer line profiles. Key questions
are how LRDs connect to standard UV-luminous AGN, whether transitional phases
exist, and whether they are observable. We present the “X-ray dot” (XRD), a compact
source at z = 3.28 observed by the NIRSpec Wide Guaranteed Time Observation survey.
The XRD exhibits LRD hallmarks: a blackbody-like (Teff ≃ 6400 K) red continuum,
a faint but blue rest-UV excess, falling mid-IR emission, and broad Balmer lines
(FWHM ∼ 2700–3200 km s−1). Unlike LRDs, however, it is remarkably X-ray luminous
(L2−10 keV = 1044.18 erg s−1) and has a continuum inflection that is blueward
of the Balmer limit. We find that the red rest-optical and blue mid-IR continuum
cannot be reproduced by standard dust-attenuated AGN models without invoking extremely
steep extinction curves, nor can the weak mid-IR emission be reconciled with well-established
X-ray–torus scaling relations. We therefore consider an alternative scenario:
the XRD may be an LRD in transition, where the gas envelope dominates the optical
continuum but optically thin sight lines allow X-rays to escape. The XRD may thus
provide a physical link between LRDs and standard AGN, offering direct evidence
that LRDs are powered by supermassive black holes and providing insight into their
accretion properties.'

text: "Early results from JWST suggest that Epoch of Reionization (EoR) galaxies
produce copious ionizing photons, which, if they escape efficiently, could cause
reionization to occur too early. We study this problem using JWST imaging and
prism spectroscopy for 412 galaxies at 4.5 < z < 9.0. We fit these data simultaneously
with stellar population and nebular emission models that include a parameter for
the fraction of ionizing photons that escape the galaxy, fesc. We find that the
ionization production efficiency, ξion = Q(H0)/LUV, increases with redshift and
decreasing UV luminosity, but shows significant scatter, (log ion z, MUV) 0.3
dex. The inferred escape fractions averaged over the population are low, ranging
from〈fesc〉 ≃ 2.6% ± 1.4% at 6 < z < 9 to 6.5% ± 2.2% at 4.5 < z < 6, with weak
or no indication of evolution with redshift. This implies that in our models most
of the ionizing photons need to be absorbed to account for the nebular emission.
We compute the impact of our results on reionization, including the distributions
for ξion and fesc, and the evolution and uncertainty of the UV luminosity function.
Considering galaxies brighter than MUV < −16 mag would produce an intergalactic
medium hydrogen-ionized fraction of xe = 0.5 at 5.3 < z < 5.8, possibly too late
compared to constraints from from quasistellar\r\nobject (QSO) sight lines. Including
fainter galaxies, MUV < −14 mag, we obtain xe = 0.5 at 6.0 < z < 8.1, fully consistent
with QSO and cosmic microwave background data. This implies that EoR galaxies
produce plenty of ionizing photons, but that these do not efficiently escape.
This may be a result of high gas column densities combined with burstier star
formation histories, which limit the time massive stars are able to clear channels
through the gas for ionizing photons to escape."

text: 'Background: Low-volume trapping columns are essential for sample enrichment,
desalting, and injection profile focusing on nano-LC–MS-based proteomics. They
enable higher sample loading, improve chromatographic performance, and protect
the analytical column by removing salts and contaminants. Recently, monolithic
trap columns with micropillar architecture have emerged as alternatives to conventionally
packed traps. This study compares the performance of a packed and a micropillar
monolithic trap column for the analysis of tryptic peptides. Methods: A tryptic
digest of HeLa cell lysate was analyzed under identical LC–MS conditions using
both trap types. Peptides were detected at 214 nm and analyzed by nano-ESI on
a Q Exactive Plus Orbitrap. Data were searched against the human UniProt database
(February 2023) using FragPipe v20.0, and statistical evaluation of MaxLFQ intensities
was performed in Perseus using Welch’s t-test and clustering analysis. Results:
Over 2500 proteins were identified with both setups. The packed trap column yielded
more total peptides, particularly those with post-translational modifications
and higher hydrophilicity, whereas the monolithic column favored peptides of intermediate
hydrophobicity. Chromatographic profiles confirmed a slight reduction in the trapping
efficiency of hydrophilic peptides by the monolithic trap. Conclusions: Trap column
design significantly influences peptide recovery and proteome coverage.'

text: Supermassive black hole binary (SMBHB) systems are expected to form as a consequence
of galaxy mergers. At subparsec separations, SMBHBs can be identified as quasars
with periodic variability, with previous periodicity searches uncovering significant
candidates. However, these searches focused primarily on sinusoidal signals, while
theoretical models and hydrodynamical simulations predict that binaries produce
more complex non-sinusoidal pulse shapes. Here we examine the efficacy of the
Lomb–Scargle periodogram (LSP; one of the most popular tools for periodicity searches
in unevenly sampled lightcurves) to detect periodicities with a sawtooth shape
mimicking results of hydrodynamical simulations. We simulate idealized well-sampled
lightcurves, lightcurves that mimic the data in the Palomar Transient Factory
(PTF) analyzed in M. Charisi et al. (2016), and lightcurves that resemble our
expectations for single-band data in the upcoming Legacy Survey of Space and Time
(LSST) of the Rubin Observatory. We approximate quasar variability with a damped
random walk (DRW) model, inject sinusoidal and sawtooth pulse shapes, and assess
their statistical significance. We find that in the presence of red noise, the
LSP detects a relatively low fraction of the sinusoidal signals (∼45%, ∼24%, and
∼23%, in the PTF-like, idealized, and LSST-like lightcurves, respectively). The
fraction is significantly reduced for sawtooth periodicity (with only ∼9% in PTF-like
and ∼1% in idealized and LSST-like lightcurves). These low recovery rates imply
that previous searches have missed the large majority of binaries. They also have
significant implications for the detection of SMBHBs in upcoming LSST necessitating
the development of advanced tools that go beyond the simple LSP.
