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

标准 DNA 条形码凭借通用引物适配性强和测序成本低等优势，广泛应用于生物多样性保护与溯源等领域。针对近缘种、杂交频繁及近期辐射演化的复杂类群，标准 DNA 条形码因序列变异度有限，分辨率不足，难以满足精准鉴定的需求。尽管基因组浅层测序获取质体全基因组（超级条形码）的策略提升了部分困难类群的鉴别率，但质体基因组的单亲遗传特性使其在杂交渐渗类群分析中存在局限。
As the nation marks its 250th anniversary, America’s rising generation is grappling with a profound sense of estrangement from traditional national pride. Rather than embracing uncritical flag-waving, young Americans view the present state of the union with deep skepticism—even while carving out enduring grounds for optimism rooted in community action, mutual care, and inclusive democratic values.

According to a study by researchers from the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS) and their domestic and international collaborators, forest recovery on land affected by fires, harvesting, and other disturbances has been the main contributor to China's forest carbon sink over the past three decades. The study was published in Nature Geoscience on August 17. A

A new study published in PNAS on August 21 reveals that a distinct population of macrophages can directly "eat" scar-forming material in the liver and promote the reversal of liver fibrosis. The finding reveals an unrecognized mechanism by which macrophages help clear fibrotic tissue: not by secreting factors, but by physically removing the extracellular matrix (ECM). The study was jointly conduct

Soil salinization poses a serious threat to global rice production. At present, the natural‑variation‑based genetic basis of rice salt tolerance remains poorly understood, and only a handful of major genes related to salt tolerance have been functionally characterized. It is critical to identify key gene modules in salt signaling pathways. In a study published in Developmental Cell on August 28, a

Embryonic stem cells (ESCs) possess the capacity for self-renewal and multilineage differentiation, along with high genome stability. Maintaining high-level ribosome biogenesis is essential for ESCs to sustain their identity, and this process begins with RNA polymerase I-mediated transcription of ribosomal RNA (rRNA) genes. In ESCs, rDNA loci exhibit a hyperactive chromatin state, characterized by

A research team led by Prof. REN Wencai from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences has achieved the wafer-scale epitaxial growth of monolayer MoSi 2 N 4 single crystals, a high-performance p-type two-dimensional (2D) semiconductor. Their findings, published on July 8 in Nature Materials , mark a significant step toward realizing complementary metal-oxide-semicond

The Euphorbia section Monadenium comprises approximately 90 species that are restricted to tropical Africa, with the greatest diversity found in East Africa. Members of this section range from geophytes and perennial herbs to succulent shrubs and small trees, many of which are endemic to arid or seasonally dry habitats. However, their evolutionary and biogeographical history remains poorly underst

Balsa wood is one of the world's fastest-growing and most commercially valuable tropical timber species. Renowned as the lightest commercial timber, it has experienced soaring global demand. However, traditional propagation techniques, such as tissue culture and cuttings, have proven difficult due to the species' abundant leaf hairs and mucilage secretion. This makes controlled hybridization the m

New research involving more than one million Australian feedlot cattle has found that the strongest predictors of death from bovine respiratory disease (BRD) are established before animals even enter the feedlot, highlighting the importance of preventive measures on source properties.

Honey bees have long been the model species for studying insect vision. However, new research shows that several smaller bee species might actually have sharper eyesight.
Physicists from the University of Amsterdam have developed a method to print three-dimensional structures in ice. Last December, the work gathered a lot of attention when the researchers 3D-printed a Christmas tree. In the scientific publication that came out this week, the researchers also show how small pillars can be printed under an angle, making it possible to print arbitrary profiles in ice that don’t need any additional support.
