text: Sperm chromatin is typically transformed by protamines into a compact and
transcriptionally inactive state1,2. Sperm cells of flowering plants lack protamines,
yet they have small, transcriptionally active nuclei with chromatin condensed
through an unknown mechanism3,4. Here we show that a histone variant, H2B.8, mediates
sperm chromatin and nuclear condensation in Arabidopsis thaliana. Loss of H2B.8
causes enlarged sperm nuclei with dispersed chromatin, whereas ectopic expression
in somatic cells produces smaller nuclei with aggregated chromatin. This result
demonstrates that H2B.8 is sufficient for chromatin condensation. H2B.8 aggregates
transcriptionally inactive AT-rich chromatin into phase-separated condensates,
which facilitates nuclear compaction without reducing transcription. Reciprocal
crosses show that mutation of h2b.8 reduces male transmission, which suggests
that H2B.8-mediated sperm compaction is important for fertility. Altogether, our
results reveal a new mechanism of nuclear compaction through global aggregation
of unexpressed chromatin. We propose that H2B.8 is an evolutionary innovation
of flowering plants that achieves nuclear condensation compatible with active
transcription.

text: "In modern sample-driven Prophet Inequality, an adversary chooses a sequence
of n items with values v1,v2,…,vn to be presented to a decision maker (DM). The
process follows in two phases. In the first phase (sampling phase), some items,
possibly selected at random, are revealed to the DM, but she can never accept
them. In the second phase, the DM is presented with the other items in a random
order and online fashion. For each item, she must make an irrevocable decision
to either accept the item and stop the process or reject the item forever and
proceed to the next item. The goal of the DM is to maximize the expected value
as compared to a Prophet (or offline algorithm) that has access to all information.
In this setting, the sampling phase has no cost and is not part of the optimization
process. However, in many scenarios, the samples are obtained as part of the decision-making
process.\r\nWe model this aspect as a two-phase Prophet Inequality where an adversary
chooses a sequence of 2n items with values v1,v2,…,v2n and the items are randomly
ordered. Finally, there are two phases of the Prophet Inequality problem with
the first n-items and the rest of the items, respectively. We show that some basic
algorithms achieve a ratio of at most 0.450. We present an algorithm that achieves
a ratio of at least 0.495. Finally, we show that for every algorithm the ratio
it can achieve is at most 0.502. Hence our algorithm is near-optimal."

text: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
a conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
universality classes of dynamics and invite their further theoretical and experimental
studies.

text: 'Memorization of the relation between entities in a dataset can lead to privacy
issues when using a trained model for question answering. We introduce Relational
Memorization (RM) to understand, quantify and control this phenomenon. While bounding
general memorization can have detrimental effects on the performance of a trained
model, bounding RM does not prevent effective learning. The difference is most
pronounced when the data distribution is long-tailed, with many queries having
only few training examples: Impeding general memorization prevents effective learning,
while impeding only relational memorization still allows learning general properties
of the underlying concepts. We formalize the notion of Relational Privacy (RP)
and, inspired by Differential Privacy (DP), we provide a possible definition of
Differential Relational Privacy (DrP). These notions can be used to describe and
compute bounds on the amount of RM in a trained model. We illustrate Relational
Privacy concepts in experiments with large-scale models for Question Answering.'

text: Photoredox-mediated Ni-catalyzed cross-couplings are powerful transformations
to form carbon–heteroatom bonds and are generally photocatalyzed by noble metal
complexes. Low-cost and easy-to-prepare carbon dots (CDs) are attractive quasi-homogeneous
photocatalyst alternatives, but their applicability is limited by their short
photoluminescence (PL) lifetimes. By tuning the surface and PL properties of CDs,
we designed colloidal CD nano-photocatalysts for a broad range of Ni-mediated
cross-couplings between aryl halides and nucleophiles. In particular, a CD decorated
with amino groups permitted coupling to a wide range of aryl halides and thiols
under mild, base-free conditions. Mechanistic studies suggested dynamic quenching
of the CD excited state by the Ni co-catalyst and identified that pyridinium iodide
(pyHI), a previously used additive in metallaphotocatalyzed cross-couplings, can
also act as a photocatalyst in such transformations.

text: We demonstrate that several visible-light-mediated carbon−heteroatom cross-coupling
reactions can be carried out using a photoactive NiII precatalyst that forms in
situ from a nickel salt and a bipyridine ligand decorated with two carbazole groups
(Ni(Czbpy)Cl2). The activation of this precatalyst towards cross-coupling reactions
follows a hitherto undisclosed mechanism that is different from previously reported
light-responsive nickel complexes that undergo metal-to-ligand charge transfer.
Theoretical and spectroscopic investigations revealed that irradiation of Ni(Czbpy)Cl2
with visible light causes an initial intraligand charge transfer event that triggers
productive catalysis. Ligand polymerization affords a porous, recyclable organic
polymer for heterogeneous nickel catalysis of cross-coupling reactions. The heterogeneous
catalyst shows stable performance in a packed-bed flow reactor during a week of
continuous operation.

text: In this work, a feed-forward artificial neural network (FF-ANN) design capable
of locating eigensolutions to Schrödinger's equation via self-supervised learning
is outlined. Based on the input potential determining the nature of the quantum
problem, the presented FF-ANN strategy identifies valid solutions solely by minimizing
Schrödinger's equation encoded in a suitably designed global loss function. In
addition to benchmark calculations of prototype systems with known analytical
solutions, the outlined methodology was also applied to experimentally accessible
quantum systems, such as the vibrational states of molecular hydrogen H2 and its
isotopologues HD and D2 as well as the torsional tunnel splitting in the phenol
molecule. It is shown that in conjunction with the use of SIREN activation functions
a high accuracy in the energy eigenvalues and wavefunctions is achieved without
the requirement to adjust the implementation to the vastly different range of
input potentials, thereby even considering problems under periodic boundary conditions.

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
R 2 was 47% in a UK Biobank holdout sample, which was 76% of the estimated h SNP
2 . 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: Chromosomal inversions have been shown to play a major role in local adaptation
by suppressing recombination between alternative arrangements and maintaining
beneficial allele combinations. However, so far, their importance relative to
the remaining genome remains largely unknown. Understanding the genetic architecture
of adaptation requires better estimates of how loci of different effect sizes
contribute to phenotypic variation. Here, we used three Swedish islands where
the marine snail Littorina saxatilis has repeatedly evolved into two distinct
ecotypes along a habitat transition. We estimated the contribution of inversion
polymorphisms to phenotypic divergence while controlling for polygenic effects
in the remaining genome using a quantitative genetics framework. We confirmed
the importance of inversions but showed that contributions of loci outside inversions
are of similar magnitude, with variable proportions dependent on the trait and
the population. Some inversions showed consistent effects across all sites, whereas
others exhibited site-specific effects, indicating that the genomic basis for
replicated phenotypic divergence is only partly shared. The contributions of sexual
dimorphism as well as environmental factors to phenotypic variation were significant
but minor compared to inversions and polygenic background. Overall, this integrated
approach provides insight into the multiple mechanisms contributing to parallel
phenotypic divergence.

text: Brains are thought to engage in predictive learning - learning to predict
upcoming stimuli - to construct an internal model of their environment. This is
especially notable for spatial navigation, as first described by Tolman’s latent
learning tasks. However, predictive learning has also been observed in sensory
cortex, in settings unrelated to spatial navigation. Apart from normative frameworks
such as active inference or efficient coding, what could be the utility of learning
to predict the patterns of occurrence of correlated stimuli? Here we show that
prediction, and thereby the construction of an internal model of sequential stimuli,
can bootstrap the learning process of a working memory task in a recurrent neural
network. We implemented predictive learning alongside working memory match-tasks,
and networks emerged to solve the prediction task first by encoding information
across time to predict upcoming stimuli, and then eavesdropped on this solution
to solve the matching task. Eavesdropping was most beneficial when neural resources
were limited. Hence, predictive learning acts as a general neural mechanism to
learn to store sensory information that can later be essential for working memory
tasks.

text: Ustilago maydis is a biotrophic phytopathogenic fungus that causes corn smut
disease. As a well-established model system, U. maydis is genetically fully accessible
with large omics datasets available and subject to various biological questions
ranging from DNA-repair, RNA-transport, and protein secretion to disease biology.
For many genetic approaches, tight control of transgene regulation is important.
Here we established an optimised version of the Tetracycline-ON (TetON) system
for U. maydis. We demonstrate the Tetracycline concentration-dependent expression
of fluorescent protein transgenes and the system’s suitability for the induced
expression of the toxic protein BCL2 Associated X-1 (Bax1). The Golden Gate compatible
vector system contains a native minimal promoter from the mating factor a-1 encoding
gene, mfa with ten copies of the tet-regulated operator (tetO) and a codon optimised
Tet-repressor (tetR*) which is translationally fused to the native transcriptional
corepressor Mql1 (UMAG_05501). The metabolism-independent transcriptional regulator
system is functional both, in liquid culture as well as on solid media in the
presence of the inducer and can become a useful tool for toxin-antitoxin studies,
identification of antifungal proteins, and to study functions of toxic gene products
in Ustilago maydis.

text: Addressing fairness concerns about machine learning models is a crucial step
towards their long-term adoption in real-world automated systems. Many approaches
for training fair models from data have been developed and an implicit assumption
about such algorithms is that they are able to recover a fair model, despite potential
historical biases in the data. In this work we show a number of impossibility
results that indicate that there is no learning algorithm that can recover a fair
model when a proportion of the dataset is subject to arbitrary manipulations.
Specifically, we prove that there are situations in which an adversary can force
any learner to return a biased classifier, with or without degrading accuracy,
and that the strength of this bias increases for learning problems with underrepresented
protected groups in the data. Our results emphasize on the importance of studying
further data corruption models of various strength and of establishing stricter
data collection practices for fairness-aware learning.

text: The self-assembly of inorganic nanoparticles (NPs) into ordered structures
(superlattices) has led to a wide range of nanomaterials with unique optical,
magnetic, electronic, and catalytic properties. Various interactions have been
employed to direct the crystallization of NPs, including van der Waals forces,
hydrogen bonding, as well as electric and magnetic dipolar interactions. Among
them, Coulombic interactions—ubiquitous in nature and the main driving force behind
the formation of many minerals, such as fluorite or rock salt—have remained largely
underexplored, owing to the rapid charge exchange between NPs bearing high densities
of opposite charges (superionic NPs). Here, we worked with superionic NPs under
conditions (room temperature, concentrated salt solutions) that preserved their
native surface charge density. We demonstrate that under these conditions, the
Coulombic interactions between superionic NPs are reminiscent of short-range intermolecular
interactions. Our methodology was used to assemble oppositely charged NPs into
high-quality superlattices exhibiting Catalan shapes. Depending on their size
ratio, the NPs assembled into either rhombic dodecahedra or triakis tetrahedra
with structures mimicking those of the ionic solids CsCl and Th3P4, respectively.
We envision that the methodology described here can be applied to a wide range
of charged NPs of various sizes, shapes, and compositions, thus facilitating the
discovery of new nanomaterials.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. For example, the controlled aggregation
of chromophores into discrete oligomers has been shown to tune their optical properties
whereas encapsulation of reactive species within molecular hosts can increase
their stability. The resazurin/resorufin pair has been widely used for detecting
redox processes in biological settings; yet, how tight confinement affects the
properties of these two dyes remains to be explored. Here, we show that a flexible
PdII6L4 coordination
cage can efficiently encapsulate both resorufin and resazurin in the form of dimers,
dramatically modulating their optical properties. Furthermore, binding within
the cage significantly decreases the reduction rate of resazurin to resorufin,
and the rate of the subsequent reduction of resorufin to dihydroresorufin. During
our studies, we also found that upon dilution, the PdII6L4
cage disassembles to afford PdII2L2
species, which lacks the ability to form inclusion complexes – a process that
can be reversed upon the addition of the strongly binding resorufin/resazurin
guests. We expect that the herein disclosed ability of a water-soluble cage to
reversibly modulate the optical and chemical properties of a molecular redox probe
will expand the versatility of synthetic fluorescent probes in biologically relevant
environments.

text: Molecular confinement effects can profoundly alter the physicochemical properties
of the confined species. A plethora of organic molecules were encapsulated within
the cavities of supramolecular hosts, and the impact of the cavity size and polarity
was widely investigated. However, the extent to which the properties of the confined
guests can be affected by the symmetry of the cage─which dictates the shape of
the cavity─remains to be understood. Here we show that cage symmetry has a dramatic
effect on the equilibrium between two isomers of the encapsulated spiropyran guests.
Working with two Pd-based coordination cages featuring similarly sized but differently
shaped hydrophobic cavities, we found a highly selective stabilization of the
isomer whose shape matches that of the cavity of the cage. A Td-symmetric cage
stabilized the spiropyrans’ colorless form and rendered them photochemically inert.
In contrast, a D2h-symmetric cage favored the colored isomer, while maintaining
reversible photoswitching between the two states of the encapsulated spiropyrans.
We also show that the switching kinetics strongly depend on the substitution pattern
on the spiropyran scaffold. This finding was used to fabricate a time-sensitive
information storage medium with tunable lifetimes of the encoded messages.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
inclusion complexes of an open-window coordination cage that can simultaneously
accommodate two guest molecules. Working with two types of guests, anthracene
derivatives and BODIPY dyes, we show that the former can substantially modify
the optical properties of the latter upon noncovalent heterodimer formation. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.

text: Optoelectronic effects differentiating absorption of right and left circularly
polarized photons in thin films of chiral materials are typically prohibitively
small for their direct photocurrent observation. Chiral metasurfaces increase
the electronic sensitivity to circular polarization, but their out-of-plane architecture
entails manufacturing and performance trade-offs. Here, we show that nanoporous
thin films of chiral nanoparticles enable high sensitivity to circular polarization
due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces.
Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine
generate a photocurrent under right-handed circularly polarized light as high
as 2.41 times higher than under left-handed circularly polarized light. The strong
plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic
modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte
interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated
detection of light ellipticity with equal sensitivity at all incident angles mimics
phenomenological aspects of polarization vision in marine animals. The simplicity
of self-assembly and sensitivity of polarization detection found in optoionic
membranes opens the door to a family of miniaturized fluidic devices for chiral
photonics.
