研究人员在高压下发现首个二维范德华重费米子超导体

重费米子超导通常发生在近藤杂化与RKKY长程磁有序竞争的量子临界点附近，是研究量子临界涨落驱动非常规超导配对的重要载体。降低晶体结构维度，量子涨落便会增强，若在二维范德华材料中实现重费米子超导，将为研究维度调控的量子临界行为和非常规超导机制提供理想平台。而二维范德华重费米子体系非常少见，近期发现的范德华层状重费米子金属CeSiI为此带来契机。该材料在常压下具有近藤相干态和长程反铁磁序，但超导电性尚未被发现。

Research on the direction of mRNA delivery has made progress

脂质纳米颗粒（LNP）是信使核糖核酸（mRNA）等核酸药物的重要递送载体，其体内传输行为高度依赖表面界面性质。聚乙二醇（PEG）修饰可提高LNP稳定性并促进其跨越生物屏障，但会削弱颗粒与细胞的相互作用，降低细胞摄取和胞内递送效率。由于LNP在体内运输与细胞递送阶段对表面性质的需求并不相同，传统静态PEG修饰难以兼顾，形成了制约递送效率提升的“PEG困境”。

食品废弃物转化为单细胞蛋白和油脂技术研究获进展

As residents' daily living standards continue to improve, the demand for high-quality protein in farming and other fields has increased significantly, and the supply is insufficient. At the same time, urban food waste production is large, and traditional disposal processes have high carbon emissions, low resource conversion efficiency, and high energy consumption. The protein supply gap and the problem of food waste disposal are superimposed, and there is an urgent need to build efficient and coordinated resource solutions.

Research on the controllable preparation and micro energy storage application of two-dimensional boride

Two-dimensional transition metal borides have broad application prospects in the field of electrochemical energy storage due to their unique electronic structure, high conductivity and rich surface chemical properties. Molybdenum boride (MoB) can be obtained by selectively etching away the aluminum (Al) layer in layered molybdenum aluminum boron (MoAlB). However, this method often faces problems such as incomplete removal of Al and re-stacking of MoB layers after etching, making it difficult to fully peel off the two-dimensional nanosheets. This will reduce the available surface area of ​​the material and prevent electrolyte ions from entering the interlayer active sites, thus restricting the performance of MoB in high-rate energy storage devices.

Study finds key protein in mammalian development

The first cell fate decision of a fertilized mammalian egg is a core scientific issue in developmental biology and is also relevant to embryo quality assessment in assisted reproduction. Although previous studies have revealed that the two-cell stage non-coding RNA LincGET mediates fate bias, the key protein factors that regulate this process have not yet been identified.

Research on the interpretability and inverse problems of corona magnetic field models has made progress

Recently, the National Space Science Center of the Chinese Academy of Sciences has conducted research on the problem of determining the surface geometric parameters of the coronal magnetic field source. It analyzed the forward and inverse problems of the potential field source surface model (PFSS) from the perspective of free boundary problems and shape optimization, and combined with the near-solar in-situ observations of the PSP satellite to construct a source surface radius optimization algorithm. This study used ACE satellite observations for independent verification to reveal the overall trend of optimal source surface radius changes with solar activity and the trade-off relationship between different observation indicators.

Research on high-performance molybdenum alloys has made progress

Recently, the Hefei Institute of Physical Sciences, Chinese Academy of Sciences, has made progress in the research of high-performance molybdenum alloys. By designing a solid-state reaction, the research team used HfB 2 to react with impurity oxygen in molybdenum powder to form high-density, highly thermally stable and evenly distributed nano-Hf particles inside the molybdenum grains. This solved the problem of traditional dispersed particles being prone to agglomeration and coarsening, and achieved a synergistic improvement in the strength, plasticity and high-temperature stability of molybdenum alloys.

Study reveals the evolution of amphibian insect landings in the Carboniferous

The establishment of complex terrestrial ecosystems is a milestone in the history of the evolution of life on Earth. It marks the complete escape of life from the constraints of the ocean and opens a new stage in the evolution of terrestrial biodiversity. Molecular clock estimates, trace fossils, and evidence from specific buried biota indicate that the evolutionary process of arthropod landings can be traced back to the Cambrian-Ordovician period, much earlier than recognized by traditional fossil records. As the animal group with the highest species diversity on Earth, there has been a long-standing research gap in the early origins and landing evolution history of insects.

研究揭示“氧化还原—钙信号”耦合调控纤毛协调摆动新机制

纤毛/鞭毛是细胞表面伸出的“天线状”保守细胞器，广泛存在于从单细胞真核生物到哺乳动物的各类细胞中。其中，运动纤毛需像船桨一样同步摆动，才能推动细胞定向游动，并通过产生定向液流，完成呼吸道黏液清除、脑脊液循环等生理过程。一旦这种“同步”被打破，或引发原发性纤毛运动障碍（PCD）、内脏左右位反转、脑积水等纤毛相关疾病，目前仍缺乏成熟的治疗方案。然而，多根纤毛究竟依靠何种信号实现协调摆动，长期以来尚不明晰。

激光反射层析实现3.3公里距离下无扫描的高分辨非视域成像

Researchers Develop Stepwise Evaporation Method to Reduce Contact Resistance in Transistors

Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received far less attention. As transistor dimensions continue to shrink, though, structural disorder in metals and at metal-semiconductor interfaces increasingly impedes carrier injection
