▲ Abstract：

Integrated circuits for communications play an enabling role when it comes to outer-space exploration thanks to their small footprint and 学网low weight. However, owing to the severe irradiation effects of space energetic particles, the implementation of radiation-tolerant electronic circuits remains a challenge. Here we report the observation of the space radiation effect on a satellite-based device and find that atomically thin materials are expected to accumulate minimal radiation-induced damage in principle. Accordingly, on the basis of a 4-inch wafer-scale monolayer 2D MoS2 process, we implement an atomic-layer transistor-based radiation-tolerant radio frequency (RF, 12–18?GHz) system with both transmitters and receivers for spaceborne communication. For on-orbit experiments, the 2D communication system was successfully launched to the approximately 517?km low Earth orbit. Notably, the system maintains a bit error rate (BER) of less than 10?8 in the transmitted data after 9?months of on-orbit operation, indicating substantial radiation tolerance and long stability. The lifespan of the 2D communication system is predicted to be about 271?years even on the geosynchronous orbit with a much harsher radiation environment. This work showcases the unique prospects of 2D electronics for spaceborne applications.

▲ Abstract：

Ultralight axion particles are 学网candidates for dark matter, conjectured to form stable, macroscopic field configurations in three-dimensional space, resulting in the possible formation of topological defect dark matter (TDM). Exploring their possible existence through a realistic parameter space requires considering interactions that extend beyond the constraints imposed by astrophysical observations of stellar cooling processes. Here we report the outcome of an experiment that monitors possible transient rotations of polarized spins, which could be induced by the interaction with topological defects, carried out by correlating five noble-gas laboratory set-ups located in two cities. Amplification and optimal noise filtering in hyperpolarized noble-gas spins greatly enhance the sensitivity to TDM-induced spin rotations, reaching approximately 10?6rad. Through this, we set constraints on the axion–nucleon coupling across an axion mass range from 10?peV to 0.2?μeV, achieving 4.1?×?1010GeV at 84?peV. These values exceed known constraints imposed by astrophysical observations, although these are obtained under different model assumptions. Our approach could further stimulate broad beyond-Standard Model physics searches, such as transient axion waves, axion stars, axion strings and Q-balls.

▲ Abstract：

Earth’s early mantle probably existed as a deep, vigorously convecting magma ocean, and its solidification is considered central to the long-term chemical and dynamical evolution of the planet. Yet a notable uncertainty is the grain size of bridgmanite—the dominant lower-mantle phase—whose nucleation behaviour at extreme pressure has remained experimentally inaccessible. Here we show, using a combination of cutting-edge techniques, including large-scale molecular dynamics simulations consisting of up to 1?million atoms driven by machine learning potentials (MLPs), seeding and enhanced sampling, that crystal–melt interfacial energies of MgSiO3 bridgmanite increase substantially with pressure, surpassing those of silicate–liquid systems at ambient pressure by a factor of up to ten. In a deep basal magma ocean (BMO), this amplified interfacial energy, combined with the potential sluggish cooling, may permit the formation of unusually large bridgmanite crystals, up to centimetre-to-metre-scale sizes. Such potentially large crystals could drive efficient fractional crystallization and cause substantial chemical differentiation and mantle compaction. If operative, this mechanism would provide a new physical pathway linking lower-mantle material properties to early Earth stratification and it motivates future geodynamic models that explicitly incorporate supercooling, compositional convection and elemental partitioning. Our findings thus offer a plausible hypothesis connecting microscopic nucleation processes with macroscopic planetary structure, refining present views of how the Earth’s interior acquired its initial compositional architecture.

▲ Abstract：

Aluminium comprises over 8% of Earth’s crust and is the most abundant metallic constituent. Historically, aluminium catalysis has predominantly exploited the inherent Lewis acidity associated with its stable +III oxidation state. Owing to its uniquely low electronegativity (1.61)—the lowest among p-block elements—and the absence of an inert-pair effect, aluminium presents formidable intrinsic challenges for engaging in catalytic redox transformations. Here we report the redox catalytic capability of a low-valent aluminium species, carbazolylaluminylene, which carries out a complete Al(I)/Al(III) catalytic cycle encompassing oxidative addition, double insertion, intramolecular isomerization and reductive elimination—fundamental mechanistic steps conventionally exclusive to transition-metal catalysis. Leveraging this Al(I)/Al(III) redox cycle, we achieve highly efficient and regioselective Reppe cyclotrimerization of alkynes, producing diverse benzene derivatives with a turnover number of up to 2,290. Through X-ray crystallographic and quantum chemical analyses, we elucidate how the dynamic nitrogen geometry within the carbazolyl ligand framework precisely modulates the aluminium coordination environment, thereby facilitating the catalytic cycle. This work fundamentally advances the conceptual understanding of main-group redox catalysis. It further sets a compelling precedent for future catalyst design and sustainable synthetic methodologies centred on aluminium redox transformations.

▲ Abstract：

Developing a unified algorithm that can learn from and generate across modalities such as text, images and video has been a fundamental challenge in artificial intelligence. Although next-token prediction has driven major advances in large language models, its extension to multimodal domains has remained limited, and diffusion models for image and video synthesis and compositional frameworks that integrate vision encoders with language models still dominate. Here we introduce Emu3, a family of multimodal models trained solely with next-token prediction. Emu3 equals the performance of well-established task-specific models across both perception and generation, matching flagship systems while removing the need for diffusion or compositional architectures. It further demonstrates coherent, high-fidelity video generation, interleaved vision–language generation and vision–language–action modelling for robotic manipulation. By reducing multimodal learning to unified token prediction, Emu3 establishes a robust foundation for large-scale multimodal modelling and offers a promising route towards unified multimodal intelligence.
