▲ Abstract：
Detailed and accurate 3D mapping of dynamic environments is essential for machines to interface with their surroundings and for human–machine interaction. Although considerable effort has been made to create the equivalent of the complementary metal–oxide–semiconductor (CMOS) image sensor for the 3D world, scalable, high-performance, reliable solutions have proven elusive. Focal plane array (FPA) sensors using frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR) have shown potential to meet all of these requirements and also provide direct measurement of radial velocity as a fourth dimension. Previous demonstrations, although promising, have not achieved the simultaneous scale and performance required by commercial applications. Here we present a large-scale, coherent LiDAR FPA enabled by comprehensive chip-scale optoelectronic integration. A 4D imaging camera is built around the FPA and used to acquire point clouds. At the core is a 352×?176-pixel 2D FMCW LiDAR FPA comprising more than 0.6million photonic components, all integrated on-chip together with their associated electronics. This represents a five times increase in pixel count with respect to previous demonstrations. The pixel architecture combines the outbound and inbound optical paths within the pixel in a monostatic configuration, together with coherent detectors and electronics. Frequency-modulated light is directed sequentially to groups of pixels by in-plane thermo-optic switches with integrated electronics for driving and calibration. An integrated serial digital interface controls both optical switching and readout synchronously. Point clouds of objects ranging from 4 to 65m with per-pixel integration time compatible with frame rates from 3 to 15frames per second (fps) are shown. This result demonstrates the capabilities of FMCW LiDAR FPA sensors as enablers of ubiquitous, low-cost, compact coherent 4D imaging cameras.

▲ Abstract：
Lymphoedema is a chronic debilitating disease caused by impaired lymphatic drainage and is characterized by tissue swelling, fat expansion, inflammation and fibrosis1,2. However, the exact mechanisms that drive lymphoedema are poorly understood. Although lymphatic vessels are known to transport cholesterol from peripheral tissues back to the systemic circulation3, the importance of impaired lymphatic drainage for cholesterol clearance in humans and its relevance to lymphoedema remain unknown. Here we show that lymphatic drainage insufficiency in human lymphoedema leads to excessive cholesterol accumulation in the lymphoedematous dermal tissue and around lymphatic vessels. Cholesterol deposition resulted in dermal adipose tissue remodelling, characterized by adipocyte hypertrophy and dysfunction, progressing to death and dermal fibrosis. Surgical intervention improved lymphatic drainage and reduced cholesterol deposition. Using two mouse models that reproduce features of human lymphoedema, we demonstrated that tissue swelling and dermal adipose tissue remodelling were ameliorated by the cholesterol-depleting agent cyclodextrin. Mechanistically, we demonstrated that cyclodextrin restored lymphatic drainage by promoting the regeneration of lymphatic vessels. This study unravels the role of impaired cholesterol clearance in driving lymphoedema and identifies tissue cholesterol as a promising therapeutic target for this currently incurable disease.

▲ Abstract：
Early development across vertebrates and insects critically relies on robustly reorganizing the cytoplasm of fertilized eggs into individualized cells. This intricate process is orchestrated by large microtubule structures that traverse the embryo, partitioning the cytoplasm into physically distinct and stable compartments. Here, despite the robustness of embryonic development, we uncover an intrinsic instability in cytoplasmic partitioning driven by the microtubule cytoskeleton. By combining experiments in cytoplasmic extract and in vivo, we reveal that embryos circumvent this instability through two distinct mechanisms: either by matching the cell-cycle duration to the time needed for the instability to unfold or by limiting microtubule nucleation. These regulatory mechanisms give rise to two possible strategies to fill the cytoplasm, which we experimentally demonstrate in zebrafish and Drosophila embryos, respectively. In zebrafish embryos, unstable microtubule waves fill the geometry of the entire embryo from the first division. Conversely, in Drosophila embryos, stable microtubule asters resulting from reduced microtubule nucleation gradually fill the cytoplasm throughout multiple divisions. Our results indicate that the temporal control of microtubule dynamics could have driven the evolutionary emergence of species-specific mechanisms for effective cytoplasmic organization. Furthermore, our study unveils a fundamental synergy between physical instabilities and biological clocks, uncovering universal strategies for rapid, robust and efficient spatial ordering in biological systems.

▲ Abstract：
The sensitivity of non-local optical measurements at low light intensities, such as those involved in long-baseline telescope arrays, is limited by fundamental quantum noise and photon losses3. Distributed quantum entanglement has been proposed as a route towards overcoming these limitations and accessing new regimes of non-local optical sensing. Here we demonstrate the use of entangled quantum memories in a quantum network of silicon–vacancy centres in diamond nanocavities to experimentally perform such non-local phase measurements. Specifically, we combine the generation of event-ready remote quantum entanglement, photon mode erasure that hides the ‘which-path’ information of temporally and spatially separated incoming optical modes and non-local, non-destructive photon heralding enabled by remote entanglement to perform a proof-of-concept entanglement-assisted differential phase measurement of weak incident light between two spatially separate stations. Demonstrating successful operation of the remote phase sensing protocol with a fibre link baseline up to 1.55km, our results provide an opportunity for a new class of quantum-enhanced optical imaging methods with potential applications ranging from long-baseline interferometry and astronomy to microscopy.

▲ Abstract：
Chiral antiferromagnets host octupole order and combine the advantages of antiferromagnets and ferromagnets. Despite the development of numerous switching strategies, the field-free full switching remains unknown, posing an important obstacle to their practical application in memory technology. Here we prepared a homo-junction constituted of Mn3Sn(0001) bottom layer and polycrystalline Mn3Sn top layer. The tilted Kagomé geometry in polycrystalline Mn3Sn divides the out-of-plane spin polarization from Mn3Sn(0001) layer into the out-of-Kagomé-plane and in-Kagomé-plane components, generating the symmetric (antiferromagnet-type) and asymmetric (ferromagnet-type) driving forces, respectively. The former accelerates octupole rotation, whereas the latter determines switching chirality. Field-free full switching is realized in the unconventional protocol that integrates the advantages of both antiferromagnetic and ferromagnetic switching. It goes beyond the conventional full-switching framework requiring perpendicular uniaxial anisotropy. An unprecedented switching efficiency is achieved, with both current density and power consumption an order of magnitude lower than in previous configurations, by virtue of the highly efficient driving forces due to spin-torque characteristics of octupole order and the ultralow energy barrier arising from easy-plane anisotropy, overcoming their trade-off in conventional protocols. The zero-field switching also shows the advantages of octupole-programmable chirality and robustness to external magnetic field.

▲ Abstract：
Dielectric polymers used in electrical energy storage require a combination of key metrics, including a high dielectric constant (K), low loss and high breakdown strength (Eb), all while being capable of operating at high temperatures. Decades of research into polymer–inorganic composites have achieved only limited success in reaching these goals. Here we introduce high-temperature immiscible blends of two dipolar polymers that, through nanophase separation, self-assemble into three-dimensional all-polymer nanocomposites. The resulting nanostructures induce coiled-chain morphology and large conformation changes, which, combined with relatively low rotational barrier and high dipole moments of both polymers, yield ultrahigh dielectric responses while maintaining a low loss across a wide temperature range. Simultaneously, the nanostructured interfaces act as barriers for mobile charges, markedly reducing conduction losses at high fields and temperatures. The all-polymer three-dimensional nanocomposites with concurrently high K, high Eb and low loss deliver unprecedented discharged energy densities at elevated temperatures. The approach is applicable to other immiscible dipolar blends, demonstrating its universality and tunability. This work addresses the urgent needs in electrical energy storage and provides a new paradigm towards high-energy-density polymer dielectrics over a broad temperature range.
