Researchers recovered five multidrug-resistant Stutzerimonas nitrititolerans isolates from 60 geese fecal samples collected at a farm in Yangzhou, China. Genome sequencing showed that all five carried chromosomal tmexC2D2-toprJ2 and bla_PST-2 resistance-associated determinants. Across 104 available genomes, complete tmexCD-toprJ clusters were uncommon, and only nine genomes carried both a complete tmexCD-toprJ cluster and bla_PST, five of which were the geese isolates.

Researchers used combinatorial solid-phase peptide synthesis and infrared thermography to screen 300 tripeptide sequences for interactions with CO₂. Two tripeptides, His(Boc)-Phe-Asn and Phe-Ala-Glu(OtBu), showed reproducible thermal responses after CO₂ exposure. The signals were reproduced on glass, functionalised cellulose, and Rink-amide resin, indicating that thermographic screening can help identify peptide candidates for further development as bioinspired CO₂-binding materials.

Researchers fabricated ultralight anisotropic SiC aerogel using corn‑stalk biomass as raw material. The study, published in Defence Technology, reveals that the material exhibits orientation‑dependent electromagnetic‑wave absorption and outstanding high-temperature insulation performance, clarifying structure‑function coupling effects of biomass‑derived anisotropic ceramic aerogels and offering a green fabrication route for adaptive multifunctional protective materials.

A research team led by Prof. SUN Dunlu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences have developed a high-energy mid-infrared laser that achieves record pulse energies among laser diode (LD)-pumped Er³⁺-doped solid-state lasers operating at 2.7 μm.

Ovarian cancer ranks as the eighth most common cancer and eighth leading cause of cancer death among women globally, with over 324,000 new cases and nearly 207,000 deaths estimated in 2022. Despite therapeutic advances, five‑year survival remains below 50% in most countries, and no screening strategy has been shown to reduce mortality in average‑risk women.

Poor dietary quality is a well known contributor to upper gastrointestinal cancer, but whether psychological distress amplifies this risk has remained unclear. 

Published in Journal of Bioresources and Bioproducts, the study abandons the long-standing "component-independent assumption" used in conventional kinetic models. Instead, it introduces a component-coupled framework based on representative volume element analysis (RVEA) and a controlled-release densification pretreatment using sulfuric acid and hydrogen peroxide. By transforming lignin-derived inhibitors into quantifiable kinetic indicators, the model captures how lignin removal dynamically exposes hemicellulose, driving the transition from slow to fast hydrolysis phases. Semi-analytical solutions deliver high computational efficiency, while explicit relationships between process parameters and kinetic behavior enable rational design of lignocellulosic biorefinery processes.

With the increasingly urgent demand for non-toxic, high-specific-impulse propellants in space propulsion systems, ammonium dinitramide (ADN)-based liquid propellants have attracted extensive attention as a new-generation green alternative to hydrazine-based fuels. However, existing ADN-based thrusters all adopt the catalytic ignition technology route, which suffers from inherent drawbacks: the catalyst cannot withstand temperatures exceeding 1500 K, long preheating times are required prior to startup (in the Prisma mission, in-flight preheating lasted 600–720 s with a single-event energy consumption of 25 kJ), and insufficient preheating may lead to "hard start" or even explosion—these issues severely constrain the rapid response capability and operational safety of the thrusters. Although active ignition methods such as resistive ignition and laser ignition have been validated at the single-droplet level, how to achieve catalyst-free electric ignition at the thruster system level and systematically evaluate its combustion characteristics remains a critical engineering problem urgently to be addressed in the field of green space propulsion.

A research team mapped hormonal and metabolic changes during molting in captive male Humboldt penguins (Spheniscus humboldti). 

In a paper published in Mycology, System and Synthetic Biotechnology, the team in Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences, developed PAMP, an open-source automated image-analysis pipeline for quantitative morphological profiling throughout the life cycle of filamentous fungi. The platform enables high-resolution characterization of fungal development from spore germination to pellet formation, reveals quantitative relationships between fungal architecture and fermentation performance, and provides a scalable tool for morphology-guided strain engineering and industrial bioprocess optimization.
