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: The epitaxial growth of a strained Ge layer, which is a promising candidate
for the channel material of a hole spin qubit, has been demonstrated on 300 mm
Si wafers using commercially available Si0.3Ge0.7 strain relaxed buffer (SRB)
layers. The assessment of the layer and the interface qualities for a buried strained
Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping
confirmed that the reduction of the growth temperature enables the 2-dimensional
growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless,
dislocations at the top and/or bottom interface of the Ge layer were observed
by means of electron channeling contrast imaging, suggesting the importance of
the careful dislocation assessment. The interface abruptness does not depend on
the selection of the precursor gases, but it is strongly influenced by the growth
temperature which affects the coverage of the surface H-passivation. The mobility
of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010
/cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the
heterostructure thanks to the high Si0.3Ge0.7 SRB quality.

text: Contraction and flow of the actin cell cortex have emerged as a common principle
by which cells reorganize their cytoplasm and take shape. However, how these cortical
flows interact with adjacent cytoplasmic components, changing their form and localization,
and how this affects cytoplasmic organization and cell shape remains unclear.
Here we show that in ascidian oocytes, the cooperative activities of cortical
actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive
oocyte cytoplasmic reorganization and shape changes following fertilization. We
show that vegetal-directed cortical actomyosin flows, established upon oocyte
fertilization, lead to both the accumulation of cortical actin at the vegetal
pole of the zygote and compression and local buckling of the adjacent elastic
solid-like myoplasm layer due to friction forces generated at their interface.
Once cortical flows have ceased, the multiple myoplasm buckles resolve into one
larger buckle, which again drives the formation of the contraction pole—a protuberance
of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings
reveal a mechanism where cortical actomyosin network flows determine cytoplasmic
reorganization and cell shape by deforming adjacent cytoplasmic components through
friction forces.

text: Imaging of the immunological synapse (IS) between dendritic cells (DCs) and
T cells in suspension is hampered by suboptimal alignment of cell-cell contacts
along the vertical imaging plane. This requires optical sectioning that often
results in unsatisfactory resolution in time and space. Here, we present a workflow
where DCs and T cells are confined between a layer of glass and polydimethylsiloxane
(PDMS) that orients the cells along one, horizontal imaging plane, allowing for
fast en-face-imaging of the DC-T cell IS.

text: Motile cells moving in multicellular organisms encounter microenvironments
of locally heterogeneous mechanochemical composition. Individual compositional
parameters like chemotactic signals, adhesiveness, and pore sizes are well known
to be sensed by motile cells, providing individual guidance cues for cellular
pathfinding. However, motile cells encounter diverse mechanochemical signals at
the same time, raising the question of how cells respond to locally diverse and
potentially competing signals on their migration routes. Here, we reveal that
motile amoeboid cells require nuclear repositioning, termed nucleokinesis, for
adaptive pathfinding in heterogeneous mechanochemical microenvironments. Using
mammalian immune cells and the amoebaDictyostelium discoideum,
we discover that frequent, rapid and long-distance nucleokinesis is a basic component
of amoeboid pathfinding, enabling cells to reorientate quickly between locally
competing cues. Amoeboid nucleokinesis comprises a two-step cell polarity switch
and is driven by myosin II-forces, sliding the nucleus from a ‘losing’ to the
‘winning’ leading edge to re-adjust the nuclear to the cellular path. Impaired
nucleokinesis distorts fast path adaptions and causes cellular arrest in the microenvironment.
Our findings establish that nucleokinesis is required for amoeboid cell navigation.
Given that motile single-cell amoebae, many immune cells, and some cancer cells
utilize an amoeboid migration strategy, these results suggest that amoeboid nucleokinesis
underlies cellular navigation during unicellular biology, immunity, and disease.

text: Whether one considers swarming insects, flocking birds, or bacterial colonies,
collective motion arises from the coordination of individuals and entails the
adjustment of their respective velocities. In particular, in close confinements,
such as those encountered by dense cell populations during development or regeneration,
collective migration can only arise coordinately. Yet, how individuals unify their
velocities is often not understood. Focusing on a finite number of cells in circular
confinements, we identify waves of polymerizing actin that function as a pacemaker
governing the speed of individual cells. We show that the onset of collective
motion coincides with the synchronization of the wave nucleation frequencies across
the population. Employing a simpler and more readily accessible mechanical model
system of active spheres, we identify the synchronization of the individuals’
internal oscillators as one of the essential requirements to reach the corresponding
collective state. The mechanical ‘toy’ experiment illustrates that the global
synchronous state is achieved by nearest neighbor coupling. We suggest by analogy
that local coupling and the synchronization of actin waves are essential for the
emergent, self-organized motion of cell collectives.

text: Immune responses rely on the rapid and coordinated migration of leukocytes.
Whereas it is well established that single-cell migration is often guided by gradients
of chemokines and other chemoattractants, it remains poorly understood how these
gradients are generated, maintained, and modulated. By combining experimental
data with theory on leukocyte chemotaxis guided by the G protein–coupled receptor
(GPCR) CCR7, we demonstrate that in addition to its role as the sensory receptor
that steers migration, CCR7 also acts as a generator and a modulator of chemotactic
gradients. Upon exposure to the CCR7 ligand CCL19, dendritic cells (DCs) effectively
internalize the receptor and ligand as part of the canonical GPCR desensitization
response. We show that CCR7 internalization also acts as an effective sink for
the chemoattractant, dynamically shaping the spatiotemporal distribution of the
chemokine. This mechanism drives complex collective migration patterns, enabling
DCs to create or sharpen chemotactic gradients. We further show that these self-generated
gradients can sustain the long-range guidance of DCs, adapt collective migration
patterns to the size and geometry of the environment, and provide a guidance cue
for other comigrating cells. Such a dual role of CCR7 as a GPCR that both senses
and consumes its ligand can thus provide a novel mode of cellular self-organization.

text: Immune cells are constantly on the move through multicellular organisms to
explore and respond to pathogens and other harmful insults. While moving, immune
cells efficiently traverse microenvironments composed of tissue cells and extracellular
fibers, which together form complex environments of various porosity, stiffness,
topography, and chemical composition. In this protocol we describe experimental
procedures to investigate immune cell migration through microenvironments of heterogeneous
porosity. In particular, we describe micro-channels, micro-pillars, and collagen
networks as cell migration paths with alternative pore size choices. Employing
micro-channels or micro-pillars that divide at junctions into alternative paths
with initially differentially sized pores allows us to precisely (1) measure the
cellular translocation time through these porous path junctions, (2) quantify
the cellular preference for individual pore sizes, and (3) image cellular components
like the nucleus and the cytoskeleton. This reductionistic experimental setup
thus can elucidate how immune cells perform decisions in complex microenvironments
of various porosity like the interstitium. The setup further allows investigation
of the underlying forces of cellular squeezing and the consequences of cellular
deformation on the integrity of the cell and its organelles. As a complementary
approach that does not require any micro-engineering expertise, we describe the
usage of three-dimensional collagen networks with different pore sizes. Whereas
we here focus on dendritic cells as a model for motile immune cells, the described
protocols are versatile as they are also applicable for other immune cell types
like neutrophils and non-immune cell types such as mesenchymal and cancer cells.
In summary, we here describe protocols to identify the mechanisms and principles
of cellular probing, decision making, and squeezing during cellular movement through
microenvironments of heterogeneous porosity.

text: Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact
electrification (CE) at the nanoscale, but converting KPFM voltage maps to charge
density maps is nontrivial due to long-range forces and complex system geometry.
Here we present a strategy using finite-element method (FEM) simulations to determine
the Green's function of the KPFM probe/insulator/ground system, which allows us
to quantitatively extract surface charge. Testing our approach with synthetic
data, we find that accounting for the atomic force microscope (AFM) tip, cone,
and cantilever is necessary to recover a known input and that existing methods
lead to gross miscalculation or even the incorrect sign of the underlying charge.
Applying it to experimental data, we demonstrate its capacity to extract realistic
surface charge densities and fine details from contact-charged surfaces. Our method
gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative
charge data over a range of experimental conditions, enabling quantitative CE
at the nanoscale.

text: 'Theoretical foundations of chaos have been predominantly laid out for finite-dimensional
dynamical systems, such as the three-body problem in classical mechanics and the
Lorenz model in dissipative systems. In contrast, many real-world chaotic phenomena,
e.g., weather, arise in systems with many (formally infinite) degrees of freedom,
which limits direct quantitative analysis of such systems using chaos theory.
In the present work, we demonstrate that the hydrodynamic pilot-wave systems offer
a bridge between low- and high-dimensional chaotic phenomena by allowing for a
systematic study of how the former connects to the latter. Specifically, we present
experimental results, which show the formation of low-dimensional chaotic attractors
upon destabilization of regular dynamics and a final transition to high-dimensional
chaos via the merging of distinct chaotic regions through a crisis bifurcation.
Moreover, we show that the post-crisis dynamics of the system can be rationalized
as consecutive scatterings from the nonattracting chaotic sets with lifetimes
following exponential distributions. '

text: 'When crawling through the body, leukocytes often traverse tissues that are
densely packed with extracellular matrix and other cells, and this raises the
question: How do leukocytes overcome compressive mechanical loads? Here, we show
that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness
requires neither force sensing via the nucleus nor adhesive interactions with
a substrate. Upon global compression of the cell body as well as local indentation
of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into
dot-like structures, providing activation platforms for Arp2/3 nucleated actin
patches. These patches locally push against the external load, which can be obstructing
collagen fibers or other cells, and thereby create space to facilitate forward
locomotion. We show in vitro and in vivo that this WASp function is rate limiting
for ameboid leukocyte migration in dense but not in loose environments and is
required for trafficking through diverse tissues such as skin and lymph nodes.'

text: 'Layered materials in which individual atomic layers are bonded by weak van
der Waals forces (vdW materials) constitute one of the most prominent platforms
for materials research. Particularly, polar vdW crystals, such as hexagonal boron
nitride (h-BN), alpha-molybdenum trioxide (α-MoO3) or alpha-vanadium pentoxide
(α-V2O5), have received significant attention in nano-optics, since they support
phonon polaritons (PhPs)―light coupled to lattice vibrations― with strong electromagnetic
confinement and low optical losses. Recently, correlative far- and near-field
studies of α-MoO3 have been demonstrated as an effective strategy to accurately
extract the permittivity of this material. Here, we use this accurately characterized
and low-loss polaritonic material to sense its local dielectric environment, namely
silica (SiO2), one of the most widespread substrates in nanotechnology. By studying
the propagation of PhPs on α-MoO3 flakes with different thicknesses laying on
SiO2 substrates via near-field microscopy (s-SNOM), we extract locally the infrared
permittivity of SiO2. Our work reveals PhPs nanoimaging as a versatile method
for the quantitative characterization of the local optical properties of dielectric
substrates, crucial for understanding and predicting the response of nanomaterials
and for the future scalability of integrated nanophotonic devices. '

text: 'Polaritons with directional in-plane propagation and ultralow losses in van
der Waals (vdW) crystals promise unprecedented manipulation of light at the nanoscale.
However, these polaritons present a crucial limitation: their directional propagation
is intrinsically determined by the crystal structure of the host material, imposing
forbidden directions of propagation. Here, we demonstrate that directional polaritons
(in-plane hyperbolic phonon polaritons) in a vdW crystal (α-phase molybdenum trioxide)
can be directed along forbidden directions by inducing an optical topological
transition, which emerges when the slab is placed on a substrate with a given
negative permittivity (4H–silicon carbide). By visualizing the transition in real
space, we observe exotic polaritonic states between mutually orthogonal hyperbolic
regimes, which unveil the topological origin of the transition: a gap opening
in the dispersion. This work provides insights into optical topological transitions
in vdW crystals, which introduce a route to direct light at the nanoscale.'

text: Phonon polaritons (PhPs)—light coupled to lattice vibrations—with in-plane
hyperbolic dispersion exhibit ray-like propagation with large wave vectors and
enhanced density of optical states along certain directions on a surface. As such,
they have raised a surge of interest, promising unprecedented manipulation of
infrared light at the nanoscale in a planar circuitry. Here, we demonstrate focusing
of in-plane hyperbolic PhPs propagating along thin slabs of α-MoO3. To that end,
we developed metallic nanoantennas of convex geometries for both efficient launching
and focusing of the polaritons. The foci obtained exhibit enhanced near-field
confinement and absorption compared to foci produced by in-plane isotropic PhPs.
Foci sizes as small as λp/4.5 = λ0/50 were achieved (λp is the polariton wavelength
and λ0 is the photon wavelength). Focusing of in-plane hyperbolic polaritons introduces
a first and most basic building block developing planar polariton optics using
in-plane anisotropic van der Waals materials.

text: There are two elementary superconducting qubit types that derive directly
from the quantum harmonic oscillator. In one, the inductor is replaced by a nonlinear
Josephson junction to realize the widely used charge qubits with a compact phase
variable and a discrete charge wave function. In the other, the junction is added
in parallel, which gives rise to an extended phase variable, continuous wave functions,
and a rich energy-level structure due to the loop topology. While the corresponding
rf superconducting quantum interference device Hamiltonian was introduced as a
quadratic quasi-one-dimensional potential approximation to describe the fluxonium
qubit implemented with long Josephson-junction arrays, in this work we implement
it directly using a linear superinductor formed by a single uninterrupted aluminum
wire. We present a large variety of qubits, all stemming from the same circuit
but with drastically different characteristic energy scales. This includes flux
and fluxonium qubits but also the recently introduced quasicharge qubit with strongly
enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.
The use of a geometric inductor results in high reproducibility of the inductive
energy as guaranteed by top-down lithography—a key ingredient for intrinsically
protected superconducting qubits.

text: Growth regulation tailors development in plants to their environment. A prominent
example of this is the response to gravity, in which shoots bend up and roots
bend down1. This paradox is based on opposite effects of the phytohormone auxin,
which promotes cell expansion in shoots while inhibiting it in roots via a yet
unknown cellular mechanism2. Here, by combining microfluidics, live imaging, genetic
engineering and phosphoproteomics in Arabidopsis thaliana, we advance understanding
of how auxin inhibits root growth. We show that auxin activates two distinct,
antagonistically acting signalling pathways that converge on rapid regulation
of apoplastic pH, a causative determinant of growth. Cell surface-based TRANSMEMBRANE
KINASE1 (TMK1) interacts with and mediates phosphorylation and activation of plasma
membrane H+-ATPases for apoplast acidification, while intracellular canonical
auxin signalling promotes net cellular H+ influx, causing apoplast alkalinization.
Simultaneous activation of these two counteracting mechanisms poises roots for
rapid, fine-tuned growth modulation in navigating complex soil environments.

text: Clathrin-mediated endocytosis is the major route of entry of cargos into cells
and thus underpins many physiological processes. During endocytosis, an area of
flat membrane is remodeled by proteins to create a spherical vesicle against intracellular
forces. The protein machinery which mediates this membrane bending in plants is
unknown. However, it is known that plant endocytosis is actin independent, thus
indicating that plants utilize a unique mechanism to mediate membrane bending
against high-turgor pressure compared to other model systems. Here, we investigate
the TPLATE complex, a plant-specific endocytosis protein complex. It has been
thought to function as a classical adaptor functioning underneath the clathrin
coat. However, by using biochemical and advanced live microscopy approaches, we
found that TPLATE is peripherally associated with clathrin-coated vesicles and
localizes at the rim of endocytosis events. As this localization is more fitting
to the protein machinery involved in membrane bending during endocytosis, we examined
cells in which the TPLATE complex was disrupted and found that the clathrin structures
present as flat patches. This suggests a requirement of the TPLATE complex for
membrane bending during plant clathrin–mediated endocytosis. Next, we used in
vitro biophysical assays to confirm that the TPLATE complex possesses protein
domains with intrinsic membrane remodeling activity. These results redefine the
role of the TPLATE complex and implicate it as a key component of the evolutionarily
distinct plant endocytosis mechanism, which mediates endocytic membrane bending
against the high-turgor pressure in plant cells.

text: Spin qubits are considered to be among the most promising candidates for building
a quantum processor. Group IV hole spin qubits have moved into the focus of interest
due to the ease of operation and compatibility with Si technology. In addition,
Ge offers the option for monolithic superconductor-semiconductor integration.
Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical
field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge
and by encoding the qubit into the singlet-triplet states of a double quantum
dot. We observe electrically controlled X and Z-rotations with tunable frequencies
exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with
echo techniques. These results show that Ge hole singlet triplet qubits outperform
their electronic Si and GaAs based counterparts in speed and coherence, respectively.
In addition, they are on par with Ge single spin qubits, but can be operated at
much lower fields underlining their potential for on chip integration with superconducting
technologies.

text: Growth regulation tailors plant development to its environment. A showcase
is response to gravity, where shoots bend up and roots down1. This paradox is
based on opposite effects of the phytohormone auxin, which promotes cell expansion
in shoots, while inhibiting it in roots via a yet unknown cellular mechanism2.
Here, by combining microfluidics, live imaging, genetic engineering and phospho-proteomics
in Arabidopsis thaliana, we advance our understanding how auxin inhibits root
growth. We show that auxin activates two distinct, antagonistically acting signalling
pathways that converge on the rapid regulation of the apoplastic pH, a causative
growth determinant. Cell surface-based TRANSMEMBRANE KINASE1 (TMK1) interacts
with and mediates phosphorylation and activation of plasma membrane H+-ATPases
for apoplast acidification, while intracellular canonical auxin signalling promotes
net cellular H+-influx, causing apoplast alkalinisation. The simultaneous activation
of these two counteracting mechanisms poises the root for a rapid, fine-tuned
growth modulation while navigating complex soil environment.

text: Phonon polaritons—light coupled to lattice vibrations—in polar van der Waals
crystals are promising candidates for controlling the flow of energy on the nanoscale
due to their strong field confinement, anisotropic propagation and ultra-long
lifetime in the picosecond range1,2,3,4,5. However, the lack of tunability of
their narrow and material-specific spectral range—the Reststrahlen band—severely
limits their technological implementation. Here, we demonstrate that intercalation
of Na atoms in the van der Waals semiconductor α-V2O5 enables a broad spectral
shift of Reststrahlen bands, and that the phonon polaritons excited show ultra-low
losses (lifetime of 4 ± 1 ps), similar to phonon polaritons in a non-intercalated
crystal (lifetime of 6 ± 1 ps). We expect our intercalation method to be applicable
to other van der Waals crystals, opening the door for the use of phonon polaritons

text: 'Cells navigating through complex tissues face a fundamental challenge: while
multiple protrusions explore different paths, the cell needs to avoid entanglement.
How a cell surveys and then corrects its own shape is poorly understood. Here,
we demonstrate that spatially distinct microtubule dynamics regulate amoeboid
cell migration by locally promoting the retraction of protrusions. In migrating
dendritic cells, local microtubule depolymerization within protrusions remote
from the microtubule organizing center triggers actomyosin contractility controlled
by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin
localization, thereby causing two effects that rate-limit locomotion: (1) impaired
cell edge coordination during path finding and (2) defective adhesion resolution.
Compromised shape control is particularly hindering in geometrically complex microenvironments,
where it leads to entanglement and ultimately fragmentation of the cell body.
We thus demonstrate that microtubules can act as a proprioceptive device: they
sense cell shape and control actomyosin retraction to sustain cellular coherence.'

text: Error analysis and data visualization of positive COVID-19 cases in 27 countries
have been performed up to August 8, 2020. This survey generally observes a progression
from early exponential growth transitioning to an intermediate power-law growth
phase, as recently suggested by Ziff and Ziff. The occurrence of logistic growth
after the power-law phase with lockdowns or social distancing may be described
as an effect of avoidance. A visualization of the power-law growth exponent over
short time windows is qualitatively similar to the Bhatia visualization for pandemic
progression. Visualizations like these can indicate the onset of second waves
and may influence social policy.
acknowledgement: I would especially like to thank Michael Sixt for encouraging me
to think about these problems while working at home due to restrictions in place.
I want to thank Nick Barton, Katka Bodova, Matthew Robinson, Simon Rella, Federico
Sau, Ivan Prieto, and Pradeep Kumar for useful discussions.

text: Recent discoveries have shown that, when two layers of van der Waals (vdW)
materials are superimposed with a relative twist angle between them, the electronic
properties of the coupled system can be dramatically altered. Here, we demonstrate
that a similar concept can be extended to the optics realm, particularly to propagating
phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks
composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic
phonon polaritons (PhPs), and image the propagation of the latter when launched
by localized sources. Our images reveal that, under a critical angle, the PhPs
isofrequency curve undergoes a topological transition, in which the propagation
of PhPs is strongly guided (canalization regime) along predetermined directions
without geometric spreading. These results demonstrate a new degree of freedom
(twist angle) for controlling the propagation of polaritons at the nanoscale with
potential for nanoimaging, (bio)-sensing, or heat management.

text: Eukaryotic cells migrate by coupling the intracellular force of the actin
cytoskeleton to the environment. While force coupling is usually mediated by transmembrane
adhesion receptors, especially those of the integrin family, amoeboid cells such
as leukocytes can migrate extremely fast despite very low adhesive forces1. Here
we show that leukocytes cannot only migrate under low adhesion but can also transmit
forces in the complete absence of transmembrane force coupling. When confined
within three-dimensional environments, they use the topographical features of
the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton
follows the texture of the substrate, creating retrograde shear forces that are
sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent
migration are not mutually exclusive, but rather are variants of the same principle
of coupling retrograde actin flow to the environment and thus can potentially
operate interchangeably and simultaneously. As adhesion-free migration is independent
of the chemical composition of the environment, it renders cells completely autonomous
in their locomotive behaviour.

can still be used effectively for specific applications."

text: During metazoan development, immune surveillance and cancer dissemination,
cells migrate in complex three-dimensional microenvironments1,2,3. These spaces
are crowded by cells and extracellular matrix, generating mazes with differently
sized gaps that are typically smaller than the diameter of the migrating cell4,5.
Most mesenchymal and epithelial cells and some—but not all—cancer cells actively
generate their migratory path using pericellular tissue proteolysis6. By contrast,
amoeboid cells such as leukocytes use non-destructive strategies of locomotion7,
raising the question how these extremely fast cells navigate through dense tissues.
Here we reveal that leukocytes sample their immediate vicinity for large pore
sizes, and are thereby able to choose the path of least resistance. This allows
them to circumnavigate local obstacles while effectively following global directional
cues such as chemotactic gradients. Pore-size discrimination is facilitated by
frontward positioning of the nucleus, which enables the cells to use their bulkiest
compartment as a mechanical gauge. Once the nucleus and the closely associated
microtubule organizing centre pass the largest pore, cytoplasmic protrusions still
lingering in smaller pores are retracted. These retractions are coordinated by
dynamic microtubules; when microtubules are disrupted, migrating cells lose coherence
and frequently fragment into migratory cytoplasmic pieces. As nuclear positioning
in front of the microtubule organizing centre is a typical feature of amoeboid
migration, our findings link the fundamental organization of cellular polarity
to the strategy of locomotion.

text: Cells migrating in multicellular organisms steadily traverse complex three-dimensional
(3D) environments. To decipher the underlying cell biology, current experimental
setups either use simplified 2D, tissue-mimetic 3D (e.g., collagen matrices) or
in vivo environments. While only in vivo experiments are truly physiological,
they do not allow for precise manipulation of environmental parameters. 2D in
vitro experiments do allow mechanical and chemical manipulations, but increasing
evidence demonstrates substantial differences of migratory mechanisms in 2D and
3D. Here, we describe simple, robust, and versatile “pillar forests” to investigate
cell migration in complex but fully controllable 3D environments. Pillar forests
are polydimethylsiloxane-based setups, in which two closely adjacent surfaces
are interconnected by arrays of micrometer-sized pillars. Changing the pillar
shape, size, height and the inter-pillar distance precisely manipulates microenvironmental
parameters (e.g., pore sizes, micro-geometry, micro-topology), while being easily
combined with chemotactic cues, surface coatings, diverse cell types and advanced
imaging techniques. Thus, pillar forests combine the advantages of 2D cell migration
assays with the precise definition of 3D environmental parameters.

text: The phytohormone auxin is the information carrier in a plethora of developmental
and physiological processes in plants(1). It has been firmly established that
canonical, nuclear auxin signalling acts through regulation of gene transcription(2).
Here, we combined microfluidics, live imaging, genetic engineering and computational
modelling to reanalyse the classical case of root growth inhibition(3) by auxin.
We show that Arabidopsis roots react to addition and removal of auxin by extremely
rapid adaptation of growth rate. This process requires intracellular auxin perception
but not transcriptional reprogramming. The formation of the canonical TIR1/AFB-Aux/IAA
co-receptor complex is required for the growth regulation, hinting to a novel,
non-transcriptional branch of this signalling pathway. Our results challenge the
current understanding of root growth regulation by auxin and suggest another,
presumably non-transcriptional, signalling output of the canonical auxin pathway.

text: Navigation of cells along gradients of guidance cues is a determining step
in many developmental and immunological processes. Gradients can either be soluble
or immobilized to tissues as demonstrated for the haptotactic migration of dendritic
cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate
how gradient characteristics govern cellular response patterns, we here introduce
an in vitro system allowing to track migratory responses of DCs to precisely controlled
immobilized gradients of CCL21. We find that haptotactic sensing depends on the
absolute CCL21 concentration and local steepness of the gradient, consistent with
a scenario where DC directionality is governed by the signal-to-noise ratio of
CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC
guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore,
we find that CCR7 signal termination by the G-protein-coupled receptor kinase
6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient
sensing in vitro and confirm those observations in vivo. These findings suggest
that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal
guidance in vivo.

text: The current-phase relation (CPR) of a Josephson junction (JJ) determines how
the supercurrent evolves with the superconducting phase difference across the
junction. Knowledge of the CPR is essential in order to understand the response
of a JJ to various external parameters. Despite the rising interest in ultraclean
encapsulated graphene JJs, the CPR of such junctions remains unknown. Here, we
use a fully gate-tunable graphene superconducting quantum intereference device
(SQUID) to determine the CPR of ballistic graphene JJs. Each of the two JJs in
the SQUID is made with graphene encapsulated in hexagonal boron nitride. By independently
controlling the critical current of the JJs, we can operate the SQUID either in
a symmetric or asymmetric configuration. The highly asymmetric SQUID allows us
to phase-bias one of the JJs and thereby directly obtain its CPR. The CPR is found
to be skewed, deviating significantly from a sinusoidal form. The skewness can
be tuned with the gate voltage and oscillates in antiphase with Fabry-Pérot resistance
oscillations of the ballistic graphene cavity. We compare our experiments with
tight-binding calculations that include realistic graphene-superconductor interfaces
and find a good qualitative agreement.

text: 'We report the enhancement of infrared absorption of chemisorbed carbon monoxide
on platinum in the gap of plasmonic nanoantennas. Our method is based on the self-assembled
formation of platinum nanoislands on nanoscopic dipole antenna arrays manufactured
via electron beam lithography. We employ systematic variations of the plasmonic
antenna resonance to precisely couple to the molecular stretch vibration of carbon
monoxide adsorbed on the platinum nanoislands. Ultimately, we reach more than
1500-fold infrared absorption enhancements, allowing for an ultrasensitive detection
of a monolayer of chemisorbed carbon monoxide. The developed procedure can be
adapted to other metal adsorbents and molecular species and could be utilized
for coverage sensing in surface catalytic reactions. '

text: "Cellular locomotion is a central hallmark of eukaryotic life. It is governed
by cell-extrinsic molecular factors, which can either emerge in the soluble phase
or as immobilized, often adhesive ligands. To encode for direction, every cue
must be present as a spatial or temporal gradient. Here, we developed a microfluidic
chamber that allows measurement of cell migration in combined response to surface
immobilized and soluble molecular gradients. As a proof of principle we study
the response of dendritic cells to their major guidance cues, chemokines. The
majority of data on chemokine gradient sensing is based on in vitro studies employing
soluble gradients. Despite evidence suggesting that in vivo chemokines are often
immobilized to sugar residues, limited information is available how cells respond
to immobilized chemokines. We tracked migration of dendritic cells towards immobilized
gradients of the chemokine CCL21 and varying superimposed soluble gradients of
CCL19. Differential migratory patterns illustrate the potential of our setup to
quantitatively study the competitive response to both types of gradients. Beyond
chemokines our approach is broadly applicable to alternative systems of chemo-
and haptotaxis such as cells migrating along gradients of adhesion receptor ligands
vs. any soluble cue. \r\n"

text: Most migrating cells extrude their front by the force of actin polymerization.
Polymerization requires an initial nucleation step, which is mediated by factors
establishing either parallel filaments in the case of filopodia or branched filaments
that form the branched lamellipodial network. Branches are considered essential
for regular cell motility and are initiated by the Arp2/3 complex, which in turn
is activated by nucleation-promoting factors of the WASP and WAVE families. Here
we employed rapid amoeboid crawling leukocytes and found that deletion of the
WAVE complex eliminated actin branching and thus lamellipodia formation. The cells
were left with parallel filaments at the leading edge, which translated, depending
on the differentiation status of the cell, into a unipolar pointed cell shape
or cells with multiple filopodia. Remarkably, unipolar cells migrated with increased
speed and enormous directional persistence, while they were unable to turn towards
chemotactic gradients. Cells with multiple filopodia retained chemotactic activity
but their migration was progressively impaired with increasing geometrical complexity
of the extracellular environment. These findings establish that diversified leading
edge protrusions serve as explorative structures while they slow down actual locomotion.
