text: 'Swimming bacteria move through a fluid by actuating their moving body parts.
They are force-free and can be described as hydrodynamic force dipoles: pushers
or pullers. This modelling description is broadly used in biological physics and
active matter research, and it has successfully predicted, for example, the superfluid
behaviour of suspensions of pushers or the bend instability and emergence of turbulent
flows in active nematics. However, this description accounts only for the translational
motion of the swimming body and neglects the effects of hydrodynamic torque dipoles,
which are relevant to bacteria with rotary motor-driven flagella, such as swimming
Escherichia coli. Here we show that the torque dipole of confined swimming E.
coli can power the persistent rotation of symmetric discs. The torque dipole leads
to a traction force on the discs, an additive mechanism that is both contactless
and independent of the orientation of the bacteria. Our results indicate that
the torque dipole of swimming E. coli is notable in confined geometries, which
is relevant to bacterial transport through porous materials, biofilms and the
development of chiral fluids.'

text: Bacteria, like eukaryotes, use conserved cytoskeletal systems for intracellular
organization. The plasmid-encoded ParMRC system forms actin-like filaments that
segregate low–copy number plasmids. In multicellular cyanobacteria such as Anabaena
sp., we found that a chromosomally encoded ParMR system has evolved into a cytoskeletal
system named CorMR with a function in cell shape control rather than DNA segregation.
Live-cell imaging, in vitro reconstitution, and cryo–electron microscopy revealed
that CorM formed dynamically unstable, antiparallel double-stranded filaments
that were recruited to the membrane by CorR through an amphipathic helix conserved
in multicellular cyanobacteria. CorMR filaments were regulated by MinC, which
excluded them from the poles and division plane. Comparative genomics indicated
that the repurposing of ParMR and Min systems coevolved with cyanobacterial multicellularity,
highlighting the evolutionary plasticity of cytoskeletal systems in bacteria.

text: The oxygen reduction reaction (ORR) remains a critical bottleneck in fuel
cells and metal-air batteries due to the lack of highly efficient electrocatalysts.
Here, we report a simple strategy for synthesizing a palladium-based heterostructured
electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits
remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability
in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd
lattice, while interstitial hydrogen doping facilitates charge transfer from Pd
to H owing to their electronegativity difference. These synergistic effects modulate
the electronic structure, thereby enhancing both activity and stability. When
employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176
mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These
findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst
for next-generation metal-air batteries and related energy technologies.

text: 'When two insulating, neutral materials are contacted and separated, they
exchange electrical charge1. Experiments have long suggested that this ‘contact
electrification’ is transitive, with different materials ordering into ‘triboelectric
series’ based on the sign of charge acquired2. At the same time, the effect is
plagued by unpredictability, preventing consensus on the mechanism and casting
doubt on the rhyme and reason that series imply3. Here we expose an unanticipated
connection between the unpredictability and order in contact electrification:
nominally identical materials initially exchange charge randomly and intransitively,
but—over repeated experiments—order into triboelectric series. We find that this
evolution is driven by the act of contact itself—samples with more contacts in
their history charge negatively to ones with fewer contacts. Capturing this ‘contact
bias’ in a minimal model, we recreate both the initial randomness and ultimate
order in numerical simulations and use it experimentally to force the appearance
of a triboelectric series of our choosing. With a set of surface-sensitive techniques
to search for the underlying alterations contact creates, we only find evidence
of nanoscale morphological changes, pointing to a mechanism strongly coupled with
mechanics. Our results highlight the centrality of contact history in contact
electrification and suggest that focusing on the unpredictability that has long
plagued the effect may hold the key to understanding it.'

text: Thermoelectric coolers (TECs) are pivotal in modern heat management but face
limitations in efficiency and manufacturing scalability. We address these challenges
by using an extrusion-based 3D printing technique to fabricate high-performance
thermoelectric materials. Our ink formulations ensure the integrity of the 3D-printed
structure and effective particle bonding during sintering, achieving record-high
figure of merit (zT) values of 1.42 for p-type bismuth antimony telluride [(Bi,Sb)2Te3]
and 1.3 for n-type silver selenide (Ag2Se) materials at room temperature. The
resulting TEC demonstrates a cooling temperature gradient of 50°C in air. Moreover,
this scalable and cost-effective method circumvents energy-intensive and time-consuming
steps, such as ingot preparation and subsequently machining processes, offering
a transformative solution for thermoelectric device production and heralding a
new era of efficient and sustainable thermoelectric technologies.

text: "Gene expression is crucial for cell differentiation, development and survival
of\r\norganisms. It consists of several steps, starting with transcription that
is mediated by\r\nRNA polymerases. These are protein machineries transcribing
and producing different\r\ntypes of RNAs. Although, the individual steps of transcription
by RNA polymerase II\r\n(Pol II) as well as the structure of Pol II has been extensively
studied, surprisingly,\r\nthere is still little known about its regulation and
assembly in cytoplasm. Among the\r\nproteins that are important in biogenesis
of Pol II are RNA polymerase II associating\r\nproteins (RPAP) and small GPN-loop
GTPases (GPN). Both of these protein groups\r\nwere shown to take essential part
in assembly of Pol II.\r\nThe aim of this project was to deepen our knowledge
in regulation of Pol II in\r\nthe cytoplasm as well as the proteins involved in
this process. Techniques of structural\r\nbiology, biochemistry and cell biology
were employed to study and characterize cytoplasmic Pol II and its interacting
partners.\r\nThis study shows for the first time the structure of cytoplasmic
Pol II at high\r\nresolution. The structure also reveals proteins interacting
with Pol II in cytoplasm,\r\nnamely GDOWN1, RPAP2. Comparing the structure of
cytoplasmic Pol II with transcribing Pol II revealed striking difference in clamp
region that is not in closed state.\r\nFurthermore, GDOWN1 and RPAP2 make steric
clashes with various transcription\r\nfactors bound to Pol II during different
stages of transcription. Even though GPN1 and\r\nGPN3 proteins were not resolved
in the cytoplasmic Pol II structure, they are part of\r\nthe complex and their
interaction with Pol II was confirmed in vitro. RPAP2 stabilizes\r\nthese proteins
on Pol II and several experiments suggest that they interact with the\r\nclamp
region. In addition, GDOWN1, RPAP2 and GPNs might keep clamp in open or\r\npartially
open state. Based on these results I propose a novel model of regulation of\r\nPol
II in cytoplasm. GDOWN1, RPAP2, GPN1 and GPN3 bind to Pol II in cytoplasm\r\nand
doing so they can prevent pre-mature binding of DNA or RNA and different transcription
factors to Pol II in cytoplasm or before engaging in transcription nucleus.\r\nThis
research contributes to the current knowledge of molecular mechanisms\r\nof Pol
II regulation in cytoplasm."

text: The SiOx anode exhibits a high specific capacity and commendable durability
for lithium-ion batteries (LIBs). However, its practical application is hindered
by significant volumetric fluctuations during lithiation/delithiation, alongside
a metastable nature, which induces mechanical instability and irreversible lithium
consumption, ultimately impairing long-term capacity retention in full-battery
cell configurations. In this study, we present a phase-engineering approach designed
to improve the structural stability of SiOx anodes for LIB applications. By incorporating
lithium fluoride, amorphous SiOx undergoes partial transformation into a quartz-like
phase, which enhances mechanical integrity and mitigates irreversible lithium
loss. This modified anode demonstrates significantly improved stability and prolonged
cycle lifespan. Through a combination of multiscale simulations and in situ characterizations,
we elucidate the stabilization mechanisms conferred by the quartz phase, providing
critical insights into the role of SiOx’s crystal structure in influencing degradation
pathways. This work introduces an accessible and efficient method for controlling
the crystallinity of SiOx, offering a practical solution to enhance the durability
of high-energy-density LIBs.

text: The transverse thermoelectric (Nernst) effect is a powerful probe for studying
the electronic and structural properties of materials. In this study, we employ
transverse thermoelectric measurements to investigate the ferroelectric distortion
in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
from PbTe and SnTe, known for their exceptional thermoelectric performance and
distinct ferroelectric properties. By leveraging Nernst measurements, we provide
direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
Haas quantum oscillations that confirm the presence of two topologically nontrivial
Fermi pockets. Density functional theory calculations show that these pockets
originate from the L and T points in the Brillouin zone of the distorted structure
within the TCI phase. Raman spectroscopy further identifies a structural phase
transition below 50 K, consistent with the quantum oscillation observations. This
observation is further substantiated by temperature-dependent synchrotron X-ray
pair distribution function analysis and transmission electron microscopy, which
confirm the local off-centering of cations at low temperature. These findings
underscore the potential of transverse thermoelectric measurements in unveiling
ferroelectric distortions and their role in modulating topological quantum states,
opening new directions for research into the synergy between ferroelectricity
and topological phases.

text: Super-resolution microscopy often entails long acquisition times of minutes
to hours. Since drifts during the acquisition adversely affect data quality, active
sample stabilization is commonly used for some of these techniques to reach their
full potential. Although drifts in the lateral plane can often be corrected after
acquisition, this is not always possible or may come with drawbacks. Therefore,
it is appealing to stabilize sample position in three dimensions (3D) during acquisition.
Various schemes for active sample stabilization have been demonstrated previously,
with some reaching sub-nanometer stability in 3D. Here, we present a scheme for
active drift correction that delivers the nanometer-scale 3D stability demanded
by state-of-the-art super-resolution techniques and is straightforward to implement
compared to previous schemes capable of reaching this level of stabilization precision.
Using a refined algorithm that can handle various types of reference structure,
without sparse signal peaks being mandatory, we stabilized sample position to
∼1 nm in 3D using objective lenses both with high and low numerical aperture.
Our implementation requires only the addition of a simple widefield imaging path
and we provide an open-source control software with graphical user interface to
facilitate easy adoption of the module. Finally, we demonstrate how this has the
potential to enhance data collection for diffraction-limited and super-resolution
imaging techniques using single-molecule localization microscopy and cryo-confocal
imaging as showcases.

text: Supercrystals represent three-dimensional orderings of colloidal nanocrystals
(NCs), showcasing collective properties in photonics, phononics, and electronics
applications.1,2 Recent studies have shown that such assemblies are directly produced
during nanocrystal reactions.3–6 However, a fundamental understanding of in situ
formed supercrystals that withstand typical NC purification processes remains
underexplored, which is important for further use. Herein, we report the reaction
precursor-mediated formation of stable PbTe supercrystals. Rationalizing the formation
of these assemblies through small-angle x-ray scattering (SAXS) measurements,
we unveil their formation mechanism. Our findings reveal that the supercrystal
formation occurs in the presence of an excess of lead oleates in the crude solution.
It should be noted that the formed supercrystals can be stabilized under specific
conditions determined by the lead oleate cluster concentration, content of trioctylphosphine
telluride (TOP-Te), NC size and the need of an annealing step at mild conditions.
Furthermore, this approach allows for the continuous growth of a secondary phase
within the supercrystal; for example in the case of PbTe supercrystals, a PbS
shell can be grown on each PbTe NC constituent, resulting in core-shell PbTe-PbS
supercrystals. Our work elucidates that reaction precursors play an important
role in in situ SC formation and stabilization, implying the possibility of applying
this knowledge to other NC reactions.

text: Very long-chain fatty acids (VLCFAs), being constituents of different types
of lipids, are critical factors in plant development, presumably due to their
impact on the endomembrane system. The VLCFAs are synthesized in the endoplasmic
reticulum by a heterotetrameric enzymatic complex including β-ketoacyl CoA reductase
1 (KCR1), whose mutant is lethal. Here, we describe the ectopic shoot meristems
(esm) mutant, a viable kcr1 allele presumably affecting surface properties of
the KCR1 protein. This kcr1-2 mutant shows reduced fatty acyl elongation that
impacts VLCFAs. The kcr1-2 plants show severe defects during different stages
of development, which all correlate with defects in polar localization and subcellular
trafficking of PIN auxin transporters and resulting asymmetric auxin distribution.
Detailed analysis of KCR1 expression and patterning defects in kcr1-2 suggests
that KCR1 plays a role in delineating boundaries around meristematic and specialized
differentiating tissues, including root and shoot meristems, initiating lateral
roots, lateral root primordia, and trichomes. In these contexts, KCR1-produced
VLCFAs may act in a non-cell-autonomous manner. Viable kcr1-2 represents a useful
tool to study VLCFA roles in plant development and highlights VLCFAs as critical
developmental factors at the interface of cell polarity and tissue development.

text: High-entropy alloys (HEAs) show great potential for catalyzing complex multi-step
reactions, but optimizing their parameters, i.e., composition, but also their
crystallinity and morphology, remains a significant challenge. In this study,
FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline
nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S)
reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells,
and pouch cells reveal that HEANS significantly enhance LSB performance, achieving
initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent
cycling stability over 1000 cycles at 3Cand maintain high-rate performance up
to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density
functional theory calculations demonstrate that amorphous HEANS provide more active
sites, better ionic conductivity and stronger chemical interactions with lithium
polysulfides (LiPS). These properties effectively suppress the shuttle effect,
promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte
interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy
barrier. Overall, this study highlights the superior catalytic properties of amorphous
2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.

text: Tribocharging, or contact electrification, is the phenomenon in which two
initially neutral materials exchange electric charge through contact and subsequent
separation. While it is widely observed in everyday life and crucial to numerous
natural processes, even the most basic aspects of tribocharging are still a mystery—what
are the charge carriers involved and what drives their exchange? This work spans
three separate projects that address different aspects of tribocharging. First,
we introduce a novel strategy combining Finite Element Method (FEM) simulations
with Kelvin Probe Force Microscopy (KPFM) to quantitatively extract surface charge
density from surface voltage maps. Second, we present a simple theoretical model
that allows for the existence of triboelectric cycles, under the assumption that
multiple charge carrying species are involved. Third, we present experimental
evidence that identical materials can spontaneously evolve into a triboelectric
series, driven by contact history. Modeling this behavior enables the replication
of experimental results with simulations, and even experimentally forcing the
appearance of a pre-designed series by manipulating contact history. Together,
the findings from these projects challenge traditional views on tribocharging,
provide new tools for probing it, and open up new avenues of research—all with
the hopes of bringing us closer to understanding this puzzling phenomenon.

text: "The internal structure of biomolecules and their organization in higher-order
arrangements are key factors governing the working principles of biological systems.
Bioimaging has successfully revealed arrangements across relevant spatial scales.
For example, cryo-electron tomography has become widely used for analyzing biomolecular
structures in situ due to its comprehensive structural visualization of near-natively
preserved samples, and its capability of sub-nm resolution via averaging. However,
the identification of molecules within crowded cellular environments is often
hindered by low contrast. Fluorescence microscopy, on the other hand, routinely
visualizes specifically labeled targets at single-molecule contrast against essentially
zero background. Moreover, it provides comparatively high throughput and is amenable
to multiplexing. Due to this complementarity, combining datasets from both modalities
acquired on the same region via correlative light and electron microscopy can
reveal novel types of information. \r\nThe spatial scale at which information
can be extracted depends on imaging resolution and correlation accuracy. Since
diffraction of light limits the resolution of conventional fluorescence microscopy
to few hundreds of nanometers, reaching the full potential of correlative imaging
requires super-resolution approaches. Performing imaging at cryogenic temperature
preserves structures in a near-native state and minimizes distortions between
the fluorescence and the electron microscopy datasets. Implementations of this
concept have achieved correlation on the scale of cellular organelles or bacterial
domains.\r\nWe have worked towards pushing correlative imaging to the single-molecule
scale by improving cryo-super-resolution microscopy, and devising a refined image
correlation workflow. As part of this project, I constructed a microscopy setup
and adopted it for super-resolution fluorescence microscopy at room temperature
and cryogenic conditions. I explored different cryo-stages and acquisition strategies.
Specifically, I developed a new scheme for correcting sample drift, thus increasing
mechanical stability during microscopy acquisitions.\r\n"

text: Zirconia nanocrystals (ZrO2 NCs) are a stable host material for lanthanides,
but their performance lags behind that of the leading NaYF4 nanomaterials. Here,
we leverage surface chemistry and core/shell architectures to uncover the contribution
of dopants at the nanocrystal surface and of dopants in the nanocrystal bulk.
We first assess the doping efficiency by ICP and find that, while Eu is almost
quantitatively incorporated, the other lanthanides (La, Ce, Tb, Tm, Er, Yb) have
about 50% incorporation efficiency over the studied doping range of 1–10%. We
then determine the nanocrystal surface chemistry using NMR spectroscopy, despite
the additional spectral line broadening caused by the paramagnetic lanthanide
dopants. By varying the surface ligands and measuring the photoluminescence, we
resolve the spectroscopic signals that are sensitive to a change in surface chemistry.
Time-resolved emission spectra further reinforce the notion of a bulk component
with a long luminescent lifetime and a surface component with a fast lifetime.
Upon shelling Eu- or Tb-doped zirconia NCs with pure zirconia, the surface component
disappears, and the photoluminescence quantum yield increases. We further functionalized
the surface of the core/shell particles with oleylphosphonic acid ligands to obtain
excellent dispersibility. These results show that lanthanide-doped zirconia NCs
can be engineered to eliminate deactivation pathways.

text: Ag2Se is a promising n-type thermoelectric material, but its performance is
limited by excessive carrier concentration, compositional inhomogeneity, and phase
instability, challenges rooted in a narrow homogeneity range and uncontrolled
Ag+ diffusion in the superionic phase. Here, we address these issues by exploiting
liquid–solid interface reactions using CdSe complexes that remove surface excess
Ag to yield stoichiometric Ag2Se and generate CdSe nanodomains that inhibit Ag+
diffusion and constrain grain growth. The resulting Ag2Se-CdSe nanocomposites
exhibit a reproducible, stable figure of merit (zT) of 1.04 between 300 and 390
K. Beyond demonstrating high performance, we elucidate the interfacial chemical
reactions that give rise to the observed microstructure and transport properties,
providing a foundation for rationally engineering interfacial chemistry to tailor
transport properties across diverse thermoelectric material systems.

text: Dielectric breakdown of physical vacuum (Schwinger effect) is the textbook
demonstration of compatibility of Relativity and Quantum theory. Although observing
this effect is still practically unachievable, its analogue generalizations have
been shown to be more readily attainable. This paper demonstrates that a gapped
Dirac semiconductor, methylammonium lead-bromide perovskite (MAPbBr3), exhibits
analogue dynamic Schwinger effect. Tunneling ionization under deep subgap mid-infrared
irradiation leads to intense photoluminescence in the visible range, in full agreement
with quasi-adiabatic theory. In addition to revealing a gapped extended system
suitable for studying the analogue Schwinger effect, this observation holds great
potential for nonperturbative field sensing, i.e., sensing electric fields through
nonperturbative light-matter interactions. First, this paper illustrates this
by measuring the local deviation from the nominally cubic phase of a perovskite
single crystal, which can be interpreted in terms of frozen-in fields. Next, it
is shown that analogue dynamic Schwinger effect can be used for nonperturbative
amplification of nonparametric upconversion process in perovskites driven simultaneously
by multiple optical fields. This discovery demonstrates the potential for material
response beyond perturbation theory in the tunneling regime, offering extremely
sensitive light detection and amplification across an ultrabroad spectral range
not accessible by conventional devices.

text: Transcription by RNA polymerase II (Pol II) can be repressed by noncoding
RNA, including the human RNA Alu. However, the mechanism by which endogenous RNAs
repress transcription remains unclear. Here we present cryogenic-electron microscopy
structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA
and RNA bind to Pol II during transcription elongation. Further, we show how distinct
domains of the general transcription factor TFIIF control repressive activity.
Together, we reveal how a noncoding RNA can regulate mammalian gene expression.
