text: 'Expansion microscopy is a relatively new approach to super-resolution imaging
that uses expandable hydrogels to isotropically increase the physical distance
between fluorophores in biological samples such as cell cultures or tissue slices.
The classic gel recipe results in an expansion factor of ~4×, with a resolution
of 60–80 nm. We have recently developed X10 microscopy, which uses a gel that
achieves an expansion factor of ~10×, with a resolution of ~25 nm. Here, we provide
a step-by-step protocol for X10 expansion microscopy. A typical experiment consists
of seven sequential stages: (i) immunostaining, (ii) anchoring, (iii) polymerization,
(iv) homogenization, (v) expansion, (vi) imaging, and (vii) validation. The protocol
presented here includes recommendations for optimization, pitfalls and their solutions,
and detailed guidelines that should increase reproducibility. Although our protocol
focuses on X10 expansion microscopy, we detail which of these suggestions are
also applicable to classic fourfold expansion microscopy. We exemplify our protocol
using primary hippocampal neurons from rats, but our approach can be used with
other primary cells or cultured cell lines of interest. This protocol will enable
any researcher with basic experience in immunostainings and access to an epifluorescence
microscope to perform super-resolution microscopy with X10. The procedure takes
3 d and requires ~5 h of actively handling the sample for labeling and expansion,
and another ~3 h for imaging and analysis.'

text: Recent technical developments in the fields of quantum electromechanics and
optomechanics have spawned nanoscale mechanical transducers with the sensitivity
to measure mechanical displacements at the femtometre scale and the ability to
convert electromagnetic signals at the single photon level. A key challenge in
this field is obtaining strong coupling between motion and electromagnetic fields
without adding additional decoherence. Here we present an electromechanical transducer
that integrates a high-frequency (0.42 GHz) hypersonic phononic crystal with a
superconducting microwave circuit. The use of a phononic bandgap crystal enables
quantum-level transduction of hypersonic mechanical motion and concurrently eliminates
decoherence caused by acoustic radiation. Devices with hypersonic mechanical frequencies
provide a natural pathway for integration with Josephson junction quantum circuits,
a leading quantum computing technology, and nanophotonic systems capable of optical
networking and distributing quantum information.

text: In today's programmable blockchains, smart contracts are limited to being
deterministic and non-probabilistic. This lack of randomness is a consequential
limitation, given that a wide variety of real-world financial contracts, such
as casino games and lotteries, depend entirely on randomness. As a result, several
ad-hoc random number generation approaches have been developed to be used in smart
contracts. These include ideas such as using an oracle or relying on the block
hash. However, these approaches are manipulatable, i.e. their output can be tampered
with by parties who might not be neutral, such as the owner of the oracle or the
miners.We propose a novel game-theoretic approach for generating provably unmanipulatable
pseudorandom numbers on the blockchain. Our approach allows smart contracts to
access a trustworthy source of randomness that does not rely on potentially compromised
miners or oracles, hence enabling the creation of a new generation of smart contracts
that are not limited to being non-probabilistic and can be drawn from the much
more general class of probabilistic programs.

text: Electron transport in two-dimensional conducting materials such as graphene,
with dominant electron–electron interaction, exhibits unusual vortex flow that
leads to a nonlocal current-field relation (negative resistance), distinct from
the classical Ohm’s law. The transport behavior of these materials is best described
by low Reynolds number hydrodynamics, where the constitutive pressure–speed relation
is Stoke’s law. Here we report evidence of such vortices observed in a viscous
flow of Newtonian fluid in a microfluidic device consisting of a rectangular cavity—analogous
to the electronic system. We extend our experimental observations to elliptic
cavities of different eccentricities, and validate them by numerically solving
bi-harmonic equation obtained for the viscous flow with no-slip boundary conditions.
We verify the existence of a predicted threshold at which vortices appear. Strikingly,
we find that a two-dimensional theoretical model captures the essential features
of three-dimensional Stokes flow in experiments.

text: 'Transcription factors, by binding to specific sequences on the DNA, control
the precise spatio-temporal expression of genes inside a cell. However, this specificity
is limited, leading to frequent incorrect binding of transcription factors that
might have deleterious consequences on the cell. By constructing a biophysical
model of TF-DNA binding in the context of gene regulation, I will first explore
how regulatory constraints can strongly shape the distribution of a population
in sequence space. Then, by directly linking this to a picture of multiple types
of transcription factors performing their functions simultaneously inside the
cell, I will explore the extent of regulatory crosstalk -- incorrect binding interactions
between transcription factors and binding sites that lead to erroneous regulatory
states -- and understand the constraints this places on the design of regulatory
systems. I will then develop a generic theoretical framework to investigate the
coevolution of multiple transcription factors and multiple binding sites, in the
context of a gene regulatory network that performs a certain function. As a particular
tractable version of this problem, I will consider the evolution of two transcription
factors when they transmit upstream signals to downstream target genes. Specifically,
I will describe the evolutionary steady states and the evolutionary pathways involved,
along with their timescales, of a system that initially undergoes a transcription
factor duplication event. To connect this important theoretical model to the prominent
biological event of transcription factor duplication giving rise to paralogous
families, I will then describe a bioinformatics analysis of C2H2 Zn-finger transcription
factors, a major family in humans, and focus on the patterns of evolution that
paralogs have undergone in their various protein domains in the recent past. '

text: We show that linear analytic cocycles where all Lyapunov exponents are negative
infinite are nilpotent. For such one-frequency cocycles we show that they can
be analytically conjugated to an upper triangular cocycle or a Jordan normal form.
As a consequence, an arbitrarily small analytic perturbation leads to distinct
Lyapunov exponents. Moreover, in the one-frequency case where the th Lyapunov
exponent is finite and the st negative infinite, we obtain a simple criterion
for domination in which case there is a splitting into a nilpotent part and an
invertible part.

text: Cell fate specification by lateral inhibition typically involves contact signaling
through the Delta-Notch signaling pathway. However, whether this is the only signaling
mode mediating lateral inhibition remains unclear. Here we show that in zebrafish
oogenesis, a group of cells within the granulosa cell layer at the oocyte animal
pole acquire elevated levels of the transcriptional coactivator TAZ in their nuclei.
One of these cells, the future micropyle precursor cell (MPC), accumulates increasingly
high levels of nuclear TAZ and grows faster than its surrounding cells, mechanically
compressing those cells, which ultimately lose TAZ from their nuclei. Strikingly,
relieving neighbor-cell compression by MPC ablation or aspiration restores nuclear
TAZ accumulation in neighboring cells, eventually leading to MPC re-specification
from these cells. Conversely, MPC specification is defective in taz−/− follicles.
These findings uncover a novel mode of lateral inhibition in cell fate specification
based on mechanical signals controlling TAZ activity.

text: P-Glycoprotein (ABCB1) and breast cancer resistance protein (ABCG2) are two
efflux transporters at the blood–brain barrier (BBB), which effectively restrict
brain distribution of diverse drugs, such as tyrosine kinase inhibitors. There
is a crucial need for pharmacological ABCB1 and ABCG2 inhibition protocols for
a more effective treatment of brain diseases. In the present study, seven marketed
drugs (osimertinib, erlotinib, nilotinib, imatinib, lapatinib, pazopanib, and
cyclosporine A) and one nonmarketed drug (tariquidar), with known in vitro ABCB1/ABCG2
inhibitory properties, were screened for their inhibitory potency at the BBB in
vivo. Positron emission tomography (PET) using the model ABCB1/ABCG2 substrate
[11C]erlotinib was performed in mice. Tested inhibitors were administered as i.v.
bolus injections at 30 min before the start of the PET scan, followed by a continuous
i.v. infusion for the duration of the PET scan. Five of the tested drugs increased
total distribution volume of [11C]erlotinib in the brain (VT,brain) compared to
vehicle-treated animals (tariquidar, + 69%; erlotinib, + 19% and +23% for the
21.5 mg/kg and the 43 mg/kg dose, respectively; imatinib, + 22%; lapatinib, +
25%; and cyclosporine A, + 49%). For all drugs, increases in [11C]erlotinib brain
distribution were lower than in Abcb1a/b(−/−)Abcg2(−/−) mice (+149%), which suggested
that only partial ABCB1/ABCG2 inhibition was reached at the mouse BBB. The plasma
concentrations of the tested drugs at the time of the PET scan were higher than
clinically achievable plasma concentrations. Some of the tested drugs led to significant
increases in blood radioactivity concentrations measured at the end of the PET
scan (erlotinib, + 103% and +113% for the 21.5 mg/kg and the 43 mg/kg dose, respectively;
imatinib, + 125%; and cyclosporine A, + 101%), which was most likely caused by
decreased hepatobiliary excretion of radioactivity. Taken together, our data suggest
that some marketed tyrosine kinase inhibitors may be repurposed to inhibit ABCB1
and ABCG2 at the BBB. From a clinical perspective, moderate increases in brain
delivery despite the administration of high i.v. doses as well as peripheral drug–drug
interactions due to transporter inhibition in clearance organs question the translatability
of this concept.

text: Pleiotropy is the well-established idea that a single mutation affects multiple
phenotypes. If a mutation has opposite effects on fitness when expressed in different
contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce
the efficacy of selection by limiting the fixation of beneficial mutations through
adaptation, and the removal of deleterious mutations through purifying selection.
Although this has been widely discussed, in particular in the context of a putative
“gender load,” it has yet to be systematically quantified. In this work, we empirically
estimate to which extent different pleiotropic regimes impede the efficacy of
selection in Drosophila melanogaster. We use whole-genome polymorphism data from
a single African population and divergence data from D. simulans to estimate the
fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction
of selection (DoS). After controlling for confounding covariates, we find that
the different pleiotropic regimes have a relatively small, but significant, effect
on selection efficacy. Specifically, our results suggest that pleiotropic sexual
antagonism may restrict the efficacy of selection, but that this conflict can
be resolved by limiting the expression of genes to the sex where they are beneficial.
Intermediate levels of pleiotropy across tissues and life stages can also lead
to maladaptation in D. melanogaster, due to inefficient purifying selection combined
with low frequency of mutations that confer a selective advantage. Thus, our study
highlights the need to consider the efficacy of selection in the context of antagonistic
pleiotropy, and of genetic conflict in general.

text: Cells need to reliably sense external ligand concentrations to achieve various
biological functions such as chemotaxis or signaling. The molecular recognition
of ligands by surface receptors is degenerate in many systems, leading to crosstalk
between ligand-receptor pairs. Crosstalk is often thought of as a deviation from
optimal specific recognition, as the binding of noncognate ligands can interfere
with the detection of the receptor's cognate ligand, possibly leading to a false
triggering of a downstream signaling pathway. Here we quantify the optimal precision
of sensing the concentrations of multiple ligands by a collection of promiscuous
receptors. We demonstrate that crosstalk can improve precision in concentration
sensing and discrimination tasks. To achieve superior precision, the additional
information about ligand concentrations contained in short binding events of the
noncognate ligand should be exploited. We present a proofreading scheme to realize
an approximate estimation of multiple ligand concentrations that reaches a precision
close to the derived optimal bounds. Our results help rationalize the observed
ubiquity of receptor crosstalk in molecular sensing.

text: Cortical networks are characterized by sparse connectivity, with synapses
found at only a subset of axo-dendritic contacts. Yet within these networks, neurons
can exhibit high connection probabilities, suggesting that cell-intrinsic factors,
not proximity, determine connectivity. Here, we identify ephrin-B3 (eB3) as a
factor that determines synapse density by mediating a cell-cell competition that
requires ephrin-B-EphB signaling. In a microisland culture system designed to
isolate cell-cell competition, we find that eB3 determines winning and losing
neurons in a contest for synapses. In a Mosaic Analysis with Double Markers (MADM)
genetic mouse model system in vivo the relative levels of eB3 control spine density
in layer 5 and 6 neurons. MADM cortical neurons in vitro reveal that eB3 controls
synapse density independently of action potential-driven activity. Our findings
illustrate a new class of competitive mechanism mediated by trans-synaptic organizing
proteins which control the number of synapses neurons receive relative to neighboring
neurons.

text: In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization
of a magnetic material results in mechanical rotation and vice versa. At the microscopic
level, this effect governs the transfer between electron spin and orbital angular
momentum, and lattice degrees of freedom, understanding which is key for molecular
magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now,
the timescales of electron-to-lattice angular momentum transfer remain unclear,
since modeling this process on a microscopic level requires the addition of an
infinite amount of quantum angular momenta. We show that this problem can be solved
by reformulating it in terms of the recently discovered angulon quasiparticles,
which results in a rotationally invariant quantum many-body theory. In particular,
we demonstrate that nonperturbative effects take place even if the electron-phonon
coupling is weak and give rise to angular momentum transfer on femtosecond timescales.

text: Blebs are cellular protrusions observed in migrating cells and in cells undergoing
spreading, cytokinesis, and apoptosis. Here we investigate the flow of cytoplasm
during bleb formation and the concurrent changes in cell volume using zebrafish
primordial germ cells (PGCs) as an in vivo model. We show that bleb inflation
occurs concomitantly with cytoplasmic inflow into it and that during this process
the total cell volume does not change. We thus show that bleb formation in primordial
germ cells results primarily from redistribution of material within the cell rather
than being driven by flow of water from an external source.

text: Both classical and recent studies suggest that chromosomal inversion polymorphisms
are important in adaptation and speciation. However, biases in discovery and reporting
of inversions make it difficult to assess their prevalence and biological importance.
Here, we use an approach based on linkage disequilibrium among markers genotyped
for samples collected across a transect between contrasting habitats to detect
chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in
a single locality for the coastal marine snail, Littorina saxatilis. Patterns
of diversity in the field and of recombination in controlled crosses provide strong
evidence that at least the majority of these rearrangements are inversions. Most
show clinal changes in frequency between habitats, suggestive of divergent selection,
but only one appears to be fixed for different arrangements in the two habitats.
Consistent with widespread evidence for balancing selection on inversion polymorphisms,
we argue that a combination of heterosis and divergent selection can explain the
observed patterns and should be considered in other systems spanning environmental
gradients.

text: 'Light is a union of electric and magnetic fields, and nowhere is the complex
relationship between these fields more evident than in the near fields of nanophotonic
structures. There, complicated electric and magnetic fields varying over subwavelength
scales are generally present, which results in photonic phenomena such as extraordinary
optical momentum, superchiral fields, and a complex spatial evolution of optical
singularities. An understanding of such phenomena requires nanoscale measurements
of the complete optical field vector. Although the sensitivity of near- field
scanning optical microscopy to the complete electromagnetic field was recently
demonstrated, a separation of different components required a priori knowledge
of the sample. Here, we introduce a robust algorithm that can disentangle all
six electric and magnetic field components from a single near-field measurement
without any numerical modeling of the structure. As examples, we unravel the fields
of two prototypical nanophotonic structures: a photonic crystal waveguide and
a plasmonic nanowire. These results pave the way for new studies of complex photonic
phenomena at the nanoscale and for the design of structures that optimize their
optical behavior.'

text: Abiotic stress poses constant challenges for plant survival and is a serious
problem for global agricultural productivity. On a molecular level, stress conditions
result in elevation of reactive oxygen species (ROS) production causing oxidative
stress associated with oxidation of proteins and nucleic acids as well as impairment
of membrane functions. Adaptation of root growth to ROS accumulation is facilitated
through modification of auxin and cytokinin hormone homeostasis. Here, we report
that in Arabidopsis root meristem, ROS-induced changes of auxin levels correspond
to decreased abundance of PIN auxin efflux carriers at the plasma membrane (PM).
Specifically, increase in H2O2 levels affects PIN2 endocytic recycling. We show
that the PIN2 intracellular trafficking during adaptation to oxidative stress
requires the function of the ADP-ribosylation factor (ARF)-guanine-nucleotide
exchange factor (GEF) BEN1, an actin-associated regulator of the trafficking from
the PM to early endosomes and, presumably, indirectly, trafficking to the vacuoles.
We propose that H2O2 levels affect the actin dynamics thus modulating ARF-GEF-dependent
trafficking of PIN2. This mechanism provides a way how root growth acclimates
to stress and adapts to a changing environment.
