A study published in Forest Ecosystems reveals that bark beetle-induced logging in Central Europe follows a 9 to 12-year cycle tied to solar activity and weather patterns. Researchers analyzed nearly 50 years of forestry and climate data from Austria, Czechia, and Slovakia, linking low solar activity to hotter, drier weather and severe beetle outbreaks, with implications for climate-informed forest management.

Research has shown that ferroptosis can overcome chemotherapy resistance induced by apoptosis, making the combination of chemotherapy and ferroptosis a very promising strategy for cancer treatment. However, the high levels of glutathione in the tumor environment and insufficient intracellular iron content limit the anticancer effects mediated by ferroptosis. Recently, a study published in Nano Research utilized the tumor environment to achieve a "multi-machine integrated" combined strategy, enhancing the therapeutic effects of chemotherapy and ferroptosis. The study was published in Nano Research with the DOI of 10.26599/NR.2025.94907298.

The Ag nanoparticles were deposited on the hBN surface, and the synergistic effect of hexagonal boron nitride nanosheets and silver nanoparticles was utilized to achieve superlubricity with very low coefficient of friction and wear rate.

A novel PbTiO₃-based perovskite system, (1-x)PbTiO₃-xBiYbO₃, has been synthesized using a distinctive high-pressure and high-temperature technique. The system exhibits an unusual enhanced tetragonalities compared to pristine PbTiO₃ (c/a = 1.064). Consequently, NTE over an extended temperature range has been realized in 0.95PbTiO₃-0.05BiYbO₃ ( = -2.18 ´ 10^-5/K, 300 - 820 K) and 0.90PbTiO₃-0.10BiYbO₃ ( = -1.85 ´ 10^-5/K, 300 - 850 K), respectively, when compared to that of pristine PbTiO₃ ( = -1.99 ´ 10^-5/K, 300 - 763 K). Our experimental and theoretical studies indicate that the improved tetragonalities and expanded NTE temperature range result from stronger Pb/Bi-O and Ti/Yb-O bond strengths, and an asymmetrically distributed charge density. The present study presents a new instance of NTE across a broad temperature range, highlighting its potential as an effective thermal expansion compensator.

Cellular ceramic structures (CCSs) are promising candidates for structural components due to their low density and superior strength. However, the brittleness and poor energy absorption of CCSs severely limit their applications. Inspired by the dual-phase interpenetrating architectures in natural materials, bioinspired dual-phase composites were developed to achieve superior strength and energy absorption simultaneously. Importantly, structural components are subjected to not only quasi-static loading but also dynamic impact in application. Although mechanical properties of dual-phase composites under quasi-static loading have been investigated, their performance under dynamic loading has rarely been revealed. Moreover, how structural parameters affect mechanical properties of CCSs-based dual-phase interpenetrating composites remains unclear.

Researchers from Beihang University, Beijing, have developed an innovative solution to address the coexistence challenges between airborne pulse radar and communication systems. Published in the Chinese Journal of Aeronautics, the study introduces a Dynamic Spectrum and Power Allocation based on Genetic Algorithm (GA-DSPA) method. This breakthrough enables optimization of spectrum and power resources, significantly improving the performance of both systems while maintaining electromagnetic compatibility.

A joint research team from the Defense Innovation Institute at the Chinese Academy of Military Science and the College of Aerospace Science and Engineering at the National University of Defense Technology has developed a novel method for satellite 3D component layout optimization based on engineering requirements. The satellite 3D component layout problem involves determining both component assignment schemes and position variables simultaneously with complex multidisciplinary constraints, making it an NP-hard multi-constrained bilevel combinatorial optimization problem. The team proposed a Mixed Integer Programming (MIP) model to formulate the heat dissipation performance objective and the constraints of component 3D geometry, system stability, and special component position, transforming the original bilevel problem into a single-level optimization problem. Case studies demonstrate that the proposed method can efficiently generate layout solutions, providing fresh insights for engineering layout design.
