  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: Under high pressures and temperatures, molecular systems with substantial
    polarization charges, such as ammonia and water, are predicted to form superionic
    phases and dense fluid states with dissociating molecules and high electrical
    conductivity. This behaviour potentially plays a role in explaining the origin
    of the multipolar magnetic fields of Uranus and Neptune, whose mantles are thought
    to result from a mixture of H2O, NH3 and CH4 ices. Determining the stability domain,
    melting curve and electrical conductivity of these superionic phases is therefore
    crucial for modelling planetary interiors and dynamos. Here we report the melting
    curve of superionic ammonia up to 300 GPa from laser-driven shock compression
    of pre-compressed samples and atomistic calculations. We show that ammonia melts
    at lower temperatures than water above 100 GPa and that fluid ammonia’s electrical
    conductivity exceeds that of water at conditions predicted by hot, super-adiabatic
    models for Uranus and Neptune, and enhances the conductivity in their fluid water-rich
    dynamo layers.

  text: The emergence of large-scale order in self-organized systems relies on local
    interactions between individual components. During bacterial cell division, FtsZ—a
    prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling
    filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments
    can form dynamic chiral assemblies. However, how the active and passive properties
    of individual filaments relate to these large-scale self-organized structures
    remains poorly understood. Here we connect single-filament properties with the
    mesoscopic scale by combining minimal active matter simulations and biochemical
    reconstitution experiments. We show that the density and flexibility of active
    chiral filaments define their global order. At intermediate densities, curved,
    flexible filaments organize into chiral rings and polar bands. An effectively
    nematic organization dominates for high densities and for straight, mutant filaments
    with increased rigidity. Our predicted phase diagram quantitatively captures these
    features, demonstrating how the flexibility, density and chirality of the active
    filaments affect their collective behaviour. Our findings shed light on the fundamental
    properties of active chiral matter and explain how treadmilling FtsZ filaments
    organize during bacterial cell division.

  text: When in equilibrium, thermal forces agitate molecules, which then diffuse,
    collide and bind to form materials. However, the space of accessible structures
    in which micron-scale particles can be organized by thermal forces is limited,
    owing to the slow dynamics and metastable states. Active agents in a passive fluid
    generate forces and flows, forming a bath with active fluctuations. Two unanswered
    questions are whether those active agents can drive the assembly of passive components
    into unconventional states and which material properties they will exhibit. Here
    we show that passive, sticky beads immersed in a bath of swimming Escherichia
    coli bacteria aggregate into unconventional clusters and gels that are controlled
    by the activity of the bath. We observe a slow but persistent rotation of the
    aggregates that originates in the chirality of the E. coli flagella and directs
    aggregation into structures that are not accessible thermally. We elucidate the
    aggregation mechanism with a numerical model of spinning, sticky beads and reproduce
    quantitatively the experimental results. We show that internal activity controls
    the phase diagram and the structure of the aggregates. Overall, our results highlight
    the promising role of active baths in designing the structural and mechanical
    properties of materials with unconventional phases.

  text: Arrays of Josephson junctions are governed by a competition between superconductivity
    and repulsive Coulomb interactions, and are expected to exhibit diverging low-temperature
    resistance when interactions exceed a critical level. Here we report a study of
    the transport and microwave response of Josephson arrays with interactions exceeding
    this level. Contrary to expectations, we observe that the array resistance drops
    dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and
    then saturates at low temperature. Applying a magnetic field, we eventually observe
    a transition to a highly resistive regime. These observations can be understood
    within a theoretical picture that accounts for the effect of thermal fluctuations
    on the insulating phase. On the basis of the agreement between experiment and
    theory, we suggest that apparent superconductivity in our Josephson arrays arises
    from melting the zero-temperature insulator.

  text: As developing tissues grow in size and undergo morphogenetic changes, their
    material properties may be altered. Such changes result from tension dynamics
    at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms
    controlling the physical state of growing tissues are unclear. We found that at
    early developmental stages, the epithelium in the developing mouse spinal cord
    maintains both high junctional tension and high fluidity. This is achieved via
    a mechanism in which interkinetic nuclear movements generate cell area dynamics
    that drive extensive cell rearrangements. Over time, the cell proliferation rate
    declines, effectively solidifying the tissue. Thus, unlike well-studied jamming
    transitions, the solidification uncovered here resembles a glass transition that
    depends on the dynamical stresses generated by proliferation and differentiation.
    Our finding that the fluidity of developing epithelia is linked to interkinetic
    nuclear movements and the dynamics of growth is likely to be relevant to multiple
    developing tissues.

  text: Embryo development requires biochemical signalling to generate patterns of
    cell fates and active mechanical forces to drive tissue shape changes. However,
    how these processes are coordinated, and how tissue patterning is preserved despite
    the cellular flows occurring during morphogenesis, remains poorly understood.
    Gastrulation is a crucial embryonic stage that involves both patterning and internalization
    of the mesendoderm germ layer tissue. Here we show that, in zebrafish embryos,
    a gradient in Nodal signalling orchestrates pattern-preserving internalization
    movements by triggering a motility-driven unjamming transition. In addition to
    its role as a morphogen determining embryo patterning, graded Nodal signalling
    mechanically subdivides the mesendoderm into a small fraction of highly protrusive
    leader cells, able to autonomously internalize via local unjamming, and less protrusive
    followers, which need to be pulled inwards by the leaders. The Nodal gradient
    further enforces a code of preferential adhesion coupling leaders to their immediate
    followers, resulting in a collective and ordered mode of internalization that
    preserves mesendoderm patterning. Integrating this dual mechanical role of Nodal
    signalling into minimal active particle simulations quantitatively predicts both
    physiological and experimentally perturbed internalization movements. This provides
    a quantitative framework for how a morphogen-encoded unjamming transition can
    bidirectionally couple tissue mechanics with patterning during complex three-dimensional
    morphogenesis.

  text: Thermalization is the inevitable fate of many complex quantum systems, whose
    dynamics allow them to fully explore the vast configuration space regardless of
    the initial state---the behaviour known as quantum ergodicity. In a quest for
    experimental realizations of coherent long-time dynamics, efforts have focused
    on ergodicity-breaking mechanisms, such as integrability and localization. The
    recent discovery of persistent revivals in quantum simulators based on Rydberg
    atoms have pointed to the existence of a new type of behaviour where the system
    rapidly relaxes for most initial conditions, while certain initial states give
    rise to non-ergodic dynamics. This collective effect has been named ”quantum many-body
    scarring’by analogy with a related form of weak ergodicity breaking that occurs
    for a single particle inside a stadium billiard potential. In this Review, we
    provide a pedagogical introduction to quantum many-body scars and highlight the
    emerging connections with the semiclassical quantization of many-body systems.
    We discuss the relation between scars and more general routes towards weak violations
    of ergodicity due to embedded algebras and non-thermal eigenstates, and highlight
    possible applications of scars in quantum technology.

  text: The early development of many organisms involves the folding of cell monolayers,
    but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic
    causes and effects of local curvature remain unclear. Here we study epithelial
    cell monolayers on corrugated hydrogels engineered into wavy patterns, examining
    how concave and convex curvatures affect cellular and nuclear shape. We find that
    substrate curvature affects monolayer thickness, which is larger in valleys than
    crests. We show that this feature generically arises in a vertex model, leading
    to the hypothesis that cells may sense curvature by modifying the thickness of
    the tissue. We find that local curvature also affects nuclear morphology and positioning,
    which we explain by extending the vertex model to take into account membrane–nucleus
    interactions, encoding thickness modulation in changes to nuclear deformation
    and position. We propose that curvature governs the spatial distribution of yes-associated
    proteins via nuclear shape and density changes. We show that curvature also induces
    significant variations in lamins, chromatin condensation and cell proliferation
    rate in folded epithelial tissues. Together, this work identifies active cell
    mechanics and nuclear mechanoadaptation as the key players of the mechanistic
    regulation of epithelia to substrate curvature.

  text: When a flat band is partially filled with electrons, strong Coulomb interactions
    between them may lead to the emergence of topological gapped states with quantized
    Hall conductivity. Such emergent topological states have been found in partially
    filled Landau levels1 and Hofstadter bands2,3; however, in both cases, a large
    magnetic field is required to produce the underlying flat band. The recent observation
    of quantum anomalous Hall effects in narrow-band moiré materials4,5,6,7 has led
    to the theoretical prediction that such phases could be realized at zero magnetic
    field8,9,10,11,12. Here we report the observation of insulators with Chern number
    C = 1 in the zero-magnetic-field limit at half-integer filling of the moiré superlattice
    unit cell in twisted monolayer–bilayer graphene7,13,14,15. Chern insulators in
    a half-filled band suggest the spontaneous doubling of the superlattice unit cell2,3,16,
    and our calculations find a ground state of the topological charge density wave
    at half-filling of the underlying band. The discovery of these topological phases
    at fractional superlattice filling enables the further pursuit of zero-magnetic-field
    phases that have fractional statistics that exist either as elementary excitations
    or bound to lattice dislocations.

  text: Partially filled Landau levels host competing electronic orders. For example,
    electron solids may prevail close to integer filling of the Landau levels before
    giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
    we report the observation of an electron solid with non-collinear spin texture
    in monolayer graphene, consistent with solidification of skyrmions3—topological
    spin textures characterized by quantized electrical charge4,5. We probe the spin
    texture of the solids using a modified Corbino geometry that allows ferromagnetic
    magnons to be launched and detected6,7. We find that magnon transport is highly
    efficient when one Landau level is filled (ν=1), consistent with quantum Hall
    ferromagnetic spin polarization. However, even minimal doping immediately quenches
    the magnon signal while leaving the vanishing low-temperature charge conductivity
    unchanged. Our results can be understood by the formation of a solid of charged
    skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
    Data near fractional fillings show evidence of several fractional skyrmion solids,
    suggesting that graphene hosts a highly tunable landscape of coupled spin and
    charge orders.

  text: Origami is rapidly transforming the design of robots1,2, deployable structures3,4,5,6
    and metamaterials7,8,9,10,11,12,13,14. However, as foldability requires a large
    number of complex compatibility conditions that are difficult to satisfy, the
    design of crease patterns is limited to heuristics and computer optimization.
    Here we introduce a systematic strategy that enables intuitive and effective design
    of complex crease patterns that are guaranteed to fold. First, we exploit symmetries
    to construct 140 distinct foldable motifs, and represent these as jigsaw puzzle
    pieces. We then show that when these pieces are fitted together they encode foldable
    crease patterns. This maps origami design to solving combinatorial problems, which
    allows us to systematically create, count and classify a vast number of crease
    patterns. We show that all of these crease patterns are pluripotent—capable of
    folding into multiple shapes—and solve exactly for the number of possible shapes
    for each pattern. Finally, we employ our framework to rationally design a crease
    pattern that folds into two independently defined target shapes, and fabricate
    such pluripotent origami. Our results provide physicists, mathematicians and engineers
    with a powerful new design strategy.

  text: Attosecond chronoscopy has revealed small but measurable delays in photoionization,
    characterized by the ejection of an electron on absorption of a single photon.
    Ionization-delay measurements in atomic targets provide a wealth of information
    about the timing of the photoelectric effect, resonances, electron correlations
    and transport. However, extending this approach to molecules presents challenges,
    such as identifying the correct ionization channels and the effect of the anisotropic
    molecular landscape on the measured delays. Here, we measure ionization delays
    from ethyl iodide around a giant dipole resonance. By using the theoretical value
    for the iodine atom as a reference, we disentangle the contribution from the functional
    ethyl group, which is responsible for the characteristic chemical reactivity of
    a molecule. We find a substantial additional delay caused by the presence of a
    functional group, which encodes the effect of the molecular potential on the departing
    electron. Such information is inaccessible to the conventional approach of measuring
    photoionization cross-sections. The results establish ionization-delay measurements
    as a valuable tool in investigating the electronic properties of molecules.

  text: Partially filled Landau levels host competing electronic orders. For example,
    electron solids may prevail close to integer filling of the Landau levels before
    giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
    we report the observation of an electron solid with non-collinear spin texture
    in monolayer graphene, consistent with solidification of skyrmions3—topological
    spin textures characterized by quantized electrical charge4,5. We probe the spin
    texture of the solids using a modified Corbino geometry that allows ferromagnetic
    magnons to be launched and detected6,7. We find that magnon transport is highly
    efficient when one Landau level is filled (ν=1), consistent with quantum Hall
    ferromagnetic spin polarization. However, even minimal doping immediately quenches
    the magnon signal while leaving the vanishing low-temperature charge conductivity
    unchanged. Our results can be understood by the formation of a solid of charged
    skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
    Data near fractional fillings show evidence of several fractional skyrmion solids,
    suggesting that graphene hosts a highly tunable landscape of coupled spin and
    charge orders.

  text: Twisted bilayer graphene has recently emerged as a platform for hosting correlated
    phenomena. For twist angles near θ ≈ 1.1°, the low-energy electronic structure
    of twisted bilayer graphene features isolated bands with a flat dispersion1,2.
    Recent experiments have observed a variety of low-temperature phases that appear
    to be driven by electron interactions, including insulating states, superconductivity
    and magnetism3,4,5,6. Here we report electrical transport measurements up to room
    temperature for twist angles varying between 0.75° and 2°. We find that the resistivity,
    ρ, scales linearly with temperature, T, over a wide range of T before falling
    again owing to interband activation. The T-linear response is much larger than
    observed in monolayer graphene for all measured devices, and in particular increases
    by more than three orders of magnitude in the range where the flat band exists.
    Our results point to the dominant role of electron–phonon scattering in twisted
    bilayer graphene, with possible implications for the origin of the observed superconductivity.

  text: 'Self-assembly is the autonomous organization of components into patterns
    or structures: an essential ingredient of biology and a desired route to complex
    organization1. At equilibrium, the structure is encoded through specific interactions2,3,4,5,6,7,8,
    at an unfavourable entropic cost for the system. An alternative approach, widely
    used by nature, uses energy input to bypass the entropy bottleneck and develop
    features otherwise impossible at equilibrium9. Dissipative building blocks that
    inject energy locally were made available by recent advances in colloidal science10,11
    but have not been used to control self-assembly. Here we show the targeted formation
    of self-powered microgears from active particles and their autonomous synchronization
    into dynamical superstructures. We use a photoactive component that consumes fuel,
    haematite, to devise phototactic microswimmers that form self-spinning microgears
    following spatiotemporal light patterns. The gears are coupled via their chemical
    clouds by diffusiophoresis12 and constitute the elementary bricks of synchronized
    superstructures, which autonomously regulate their dynamics. The results are quantitatively
    rationalized on the basis of a stochastic description of diffusio-phoretic oscillators
    dynamically coupled by chemical gradients. Our findings harness non-equilibrium
    phoretic phenomena to program interactions and direct self-assembly with fidelity
    and specificity. It lays the groundwork for the autonomous construction of dynamical
    architectures and functional micro-machinery.'

  text: The ability of biological molecules to replicate themselves is the foundation
    of life, requiring a complex cellular machinery. However, a range of aberrant
    processes involve the self-replication of pathological protein structures without
    any additional assistance. One example is the autocatalytic generation of pathological
    protein aggregates, including amyloid fibrils, involved in neurodegenerative disorders.
    Here, we use computer simulations to identify the necessary requirements for the
    self-replication of fibrillar assemblies of proteins. We establish that a key
    physical determinant for this process is the affinity of proteins for the surfaces
    of fibrils. We find that self-replication can take place only in a very narrow
    regime of inter-protein interactions, implying a high level of sensitivity to
    system parameters and experimental conditions. We then compare our theoretical
    predictions with kinetic and biosensor measurements of fibrils formed from the
    Aβ peptide associated with Alzheimer’s disease. Our results show a quantitative
    connection between the kinetics of self-replication and the surface coverage of
    fibrils by monomeric proteins. These findings reveal the fundamental physical
    requirements for the formation of supra-molecular structures able to replicate
    themselves, and shed light on mechanisms in play in the proliferation of protein
    aggregates in nature.
