text: Metazoan development relies on the formation and remodeling of cell-cell contacts.
Dynamic reorganization of adhesion receptors and the actomyosin cell cortex in
space and time plays a central role in cell-cell contact formation and maturation.
Nevertheless, how this process is mechanistically achieved when new contacts are
formed remains unclear. Here, by building a biomimetic assay composed of progenitor
cells adhering to supported lipid bilayers functionalized with E-cadherin ectodomains,
we show that cortical F-actin flows, driven by the depletion of myosin-2 at the
cell contact center, mediate the dynamic reorganization of adhesion receptors
and cell cortex at the contact. E-cadherin-dependent downregulation of the small
GTPase RhoA at the forming contact leads to both a depletion of myosin-2 and a
decrease of F-actin at the contact center. At the contact rim, in contrast, myosin-2
becomes enriched by the retraction of bleb-like protrusions, resulting in a cortical
tension gradient from the contact rim to its center. This tension gradient, in
turn, triggers centrifugal F-actin flows, leading to further accumulation of F-actin
at the contact rim and the progressive redistribution of E-cadherin from the contact
center to the rim. Eventually, this combination of actomyosin downregulation and
flows at the contact determines the characteristic molecular organization, with
E-cadherin and F-actin accumulating at the contact rim, where they are needed
to mechanically link the contractile cortices of the adhering cells.

text: Frequency-stable lasers form the back bone of precision measurements in science
and technology. Such lasers typically attain their stability through frequency
locking to reference cavities. State-of-the-art locking performances to date had
been achieved using frequency modulation based methods, complemented with active
drift cancellation systems. We demonstrate an all passive, modulation-free laser-cavity
locking technique (squash locking) that utilizes changes in spatial beam ellipticity
for error signal generation, and a coherent polarization post-selection for noise
resilience. By comparing two identically built proof-of-principle systems, we
show a frequency locking instability of 5×10−7 relative to
the cavity linewidth at 10 s averaging. The results surpass the demonstrated performances
of methods engineered over the last five decades, potentially enabling an advancement
in the precision control of lasers, while creating avenues for bridging the performance
gaps between industrial grade lasers with scientific ones due to the afforded
simplicity and scalability.

text: "We consider a natural problem dealing with weighted packet selection across
a rechargeable link, which e.g., finds applications in cryptocurrency networks.
The capacity of a link (u, v) is determined by how many nodes u and v allocate
for this link. Specifically, the input is a finite ordered sequence of packets
that arrive in both directions along a link. Given (u, v) and a packet of weight
x going from u to v, node u can either accept or reject the packet. If u accepts
the packet, the capacity on link (u, v) decreases by x. Correspondingly, v's capacity
on \r\n increases by x. If a node rejects the packet, this will entail a cost
affinely linear in the weight of the packet. A link is “rechargeable” in the sense
that the total capacity of the link has to remain constant, but the allocation
of capacity at the ends of the link can depend arbitrarily on the nodes' decisions.
The goal is to minimise the sum of the capacity injected into the link and the
cost of rejecting packets. We show that the problem is NP-hard, but can be approximated
efficiently with a ratio of (1+E) . (1+3) for some arbitrary E>0."

text: Superconductor/semiconductor hybrid devices have attracted increasing interest
in the past years. Superconducting electronics aims to complement semiconductor
technology, while hybrid architectures are at the forefront of new ideas such
as topological superconductivity and protected qubits. In this work, we engineer
the induced superconductivity in two-dimensional germanium hole gas by varying
the distance between the quantum well and the aluminum. We demonstrate a hard
superconducting gap and realize an electrically and flux tunable superconducting
diode using a superconducting quantum interference device (SQUID). This allows
to tune the current phase relation (CPR), to a regime where single Cooper pair
tunneling is suppressed, creating a sin(2y) CPR. Shapiro experiments complement
this interpretation and the microwave drive allows to create a diode with ≈ 100%
efficiency. The reported results open up the path towards integration of spin
qubit devices, microwave resonators and (protected) superconducting qubits on the
same silicon technology compatible platform.

text: We study a random matching problem on closed compact 2 -dimensional Riemannian
manifolds (with respect to the squared Riemannian distance), with samples of random
points whose common law is absolutely continuous with respect to the volume measure
with strictly positive and bounded density. We show that given two sequences of
numbers n and m=m(n) of points, asymptotically equivalent as n goes to infinity,
the optimal transport plan between the two empirical measures μn and νm is
quantitatively well-approximated by (Id,exp(∇hn))#μn where hn solves a linear
elliptic PDE obtained by a regularized first-order linearization of the Monge-Ampère
equation. This is obtained in the case of samples of correlated random points
for which a stretched exponential decay of the α -mixing coefficient holds and
for a class of discrete-time Markov chains having a unique absolutely continuous
invariant measure with respect to the volume measure.

text: "Mosaic analysis with double markers (MADM) technology enables the sparse
labeling of genetically defined neurons. We present a protocol for time-lapse
imaging of cortical projection neuron migration in mice using MADM. We describe
steps for the isolation, culturing, and 4D imaging of neuronal dynamics in MADM-labeled
brain tissue. While this protocol is compatible with other single-cell labeling
methods, the MADM approach provides a genetic platform for the functional assessment
of cell-autonomous candidate gene function and the relative contribution of non-cell-autonomous
effects.\r\n\r\nFor complete details on the use and execution of this protocol,

text: The plant-signaling molecule auxin triggers fast and slow cellular responses
across land plants and algae. The nuclear auxin pathway mediates gene expression
and controls growth and development in land plants, but this pathway is absent
from algal sister groups. Several components of rapid responses have been identified
in Arabidopsis, but it is unknown if these are part of a conserved mechanism.
We recently identified a fast, proteome-wide phosphorylation response to auxin.
Here, we show that this response occurs across 5 land plant and algal species
and converges on a core group of shared targets. We found conserved rapid physiological
responses to auxin in the same species and identified rapidly accelerated fibrosarcoma
(RAF)-like protein kinases as central mediators of auxin-triggered phosphorylation
across species. Genetic analysis connects this kinase to both auxin-triggered
protein phosphorylation and rapid cellular response, thus identifying an ancient
mechanism for fast auxin responses in the green lineage.

text: Bacteria divide by binary fission. The protein machine responsible for this
process is the divisome, a transient assembly of more than 30 proteins in and
on the surface of the cytoplasmic membrane. Together, they constrict the cell
envelope and remodel the peptidoglycan layer to eventually split the cell into
two. For Escherichia coli, most molecular players involved in this process have
probably been identified, but obtaining the quantitative information needed for
a mechanistic understanding can often not be achieved from experiments in vivo
alone. Since the discovery of the Z-ring more than 30 years ago, in vitro reconstitution
experiments have been crucial to shed light on molecular processes normally hidden
in the complex environment of the living cell. In this review, we summarize how
rebuilding the divisome from purified components – or at least parts of it - have
been instrumental to obtain the detailed mechanistic understanding of the bacterial
cell division machinery that we have today.

text: The physical conditions giving rise to high escape fractions of ionizing radiation
(LyC fesc) in star-forming galaxies – most likely protagonists of cosmic reionization
– are not yet fully understood. Using the VLT/MUSE observations of ∼1400 Ly α
emitters at 2.9 < z < 6.7, we compare stacked rest-frame UV spectra
of candidates for LyC leakers and non-leakers selected based on their Ly α profiles.
We find that the stacks of potential LyC leakers, i.e. galaxies with narrow, symmetric
Ly α profiles with small peak separation, generally show (i) strong nebular O iii]λ1666,
[Si iii]λ1883, and [C iii]λ1907 +C iii]λ1909 emission, indicating a high-ionization
state of the interstellar medium (ISM); (ii) high equivalent widths of He iiλ1640
(∼1 − 3 Å), suggesting the presence of hard ionizing radiation fields; (iii) Si ii*λ1533
emission, revealing substantial amounts of neutral hydrogen off the line of sight;
(iv) high C ivλλ1548,1550 to [C iii]λ1907 +C iii]λ1909 ratios (C iv/C iii] ≳0.75)
, signalling the presence of low column density channels in the ISM. In contrast,
the stacks with broad, asymmetric Ly α profiles with large peak separation show
weak nebular emission lines, low He iiλ1640 equivalent widths (≲1 Å), and low
C iv/C iii] (≲0.25), implying low-ionization states and high-neutral hydrogen
column densities. Our results suggest that C iv/C iii] might be sensitive to the
physical conditions that govern LyC photon escape, providing a promising tool
for identification of ionizing sources among star-forming galaxies in the epoch
of reionization.

text: Elaborate sexual signals are thought to have evolved and be maintained to
serve as honest indicators of signaller quality. One measure of quality is health,
which can be affected by parasite infection. Cnemaspis mysoriensis is a diurnal
gecko that is often infested with ectoparasites in the wild, and males of this
species express visual (coloured gular patches) and chemical (femoral gland secretions)
traits that receivers could assess during social interactions. In this paper,
we tested whether ectoparasites affect individual health, and whether signal quality
is an indicator of ectoparasite levels. In wild lizards, we found that ectoparasite
level was negatively correlated with body condition in both sexes. Moreover, some
characteristics of both visual and chemical traits in males were strongly associated
with ectoparasite levels. Specifically, males with higher ectoparasite levels
had yellow gular patches with lower brightness and chroma, and chemical secretions
with a lower proportion of aromatic compounds. We then determined whether ectoparasite
levels in males influence female behaviour. Using sequential choice trials, wherein
females were provided with either the visual or the chemical signals of wild-caught
males that varied in ectoparasite level, we found that only chemical secretions
evoked an elevated female response towards less parasitised males. Simultaneous
choice trials in which females were exposed to the chemical secretions from males
that varied in parasite level further confirmed a preference for males with lower
parasites loads. Overall, we find that although health (body condition) or ectoparasite
load can be honestly advertised through multiple modalities, the parasite-mediated
female response is exclusively driven by chemical signals.
