Study Reveals How Macrophages "Eat" Liver Scars Tissue to Reverse Fibrosis

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

Researchers Reveal Novel Key Gene Controlling Salt Tolerance in Rice

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

High-entropy Electrode Improves Efficiency of Green Hydrogen Production

Water electrolysis uses renewable electricity to produce clean hydrogen. Among various technologies, anion-exchange membrane (AEM) water electrolysis combines the advantages of alkaline systems and proton-exchange membrane systems. However, its large-scale application is limited by slow oxygen evolution reaction and the need for catalysts with high activity and long-term stability. In a study publ

Tcf15 Safeguards Ribosome Biogenesis and Genome Stability in Embryonic Stem Cells

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

Scientists Achieve Wafer-Scale Growth of High-Performance P-Type 2D Semiconductor MoSi 2 N 4 Single Crystals

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

Study Traces Origin of African Succulent Euphorbia Section Monadenium to Early Miocene

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

Trait-Based Framework Accelerates Breeding of Light Wood Trees

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

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
