Summary: An increased frequency of droughts due to climate change can cause stress for soil microorganisms in peatlands, but a study in Southern Sweden found that methane producing and oxidizing microbial communities showed resilience to drought. The research also showed that while methane emissions are reduced during drought, more resilient methanogens and methanotrophs are expected to be present under future climate conditions.

Summary: This study explored the use of hydroxyapatite-gravel media in constructed wetlands (HA CWs) to effectively adsorb fluoride (F) and heavy metals (HMs) and enhance nitrate (NO3--N) reduction. The results showed that HA CWs had significantly higher removal efficiency for F, Cr, As, and NO3--N compared to conventional gravel substrate (CK CWs). HA substrate in CWs promoted the growth of wetland plants and enriched key functional genes related to nitrogen biotransformation, energy metabolism, and metal ion reduction.

Summary: This study assessed the production of the biopolymer polyhydroxybutyrate (PHB) by alphaproteobacterial methanotrophs under different nitrogen sources. Results showed that atmospheric nitrogen was the most favorable nitrogen source for PHB production, followed by ammonium and nitrate. A novel staining method for in vivo quantification of PHB production was found to be faster and more efficient than traditional methods.

Summary: This study used metagenomics and genomics to analyze the abundance of genes associated with heavy metal resistance and tolerance in the rhizosphere microbiome of Avicennia germinans in a semi-arid mangrove in La Guajira, Colombia. The study identified a total of 28 genes associated with tolerance and 49 genes related to resistance to heavy metals. Genes associated with Cu tolerance, particularly cusA and copA, were the most abundant. The Vibrio fluvialis isolate showed the ability to tolerate Cu, Ni, Zn, and Cd. The study provides insights into the potential of mangrove microorganisms to tolerate and resist heavy metals and the influence of salinity on their abundance.

Summary: Accumulating evidences have shown that endophytes play a significant role in regulating plant growth, communication, and stress tolerance. They establish a mutualistic relationship with plants, benefiting both parties. In agriculture, endophytic fungi act as biostimulants to enhance crop production and protection, offering eco-friendly ways to improve quantity and quality without harming the ecosystem. Understanding the diverse roles of endophytes can contribute to crop improvement and sustainability.

Summary: Boreal lakes and ponds play a significant role in methane emissions, regulated by methane-oxidizing bacteria. The study revealed that gammaproteobacterial methanotrophs dominate, while alphaproteobacterial methanotrophs may be more abundant in low CH4 environments. Additionally, anaerobic methanotrophs may be active even in oxygenated layers.

Summary: Soil salinization and heavy metal contamination pose significant challenges to global agricultural systems. This study investigates the response of soil microbial communities to these stress factors and identifies potential phylotypes that can tolerate these conditions and promote plant growth. The results suggest that farms in the Indus basin region of Pakistan are at risk due to salinization and excessive levels of toxic heavy metals, which could negatively impact crop and human health. The study also highlights the importance of soil microbial communities in nutrient cycling, pathogen suppression, and plant stress tolerance.

Summary: Vertical structuring of methanotrophic communities in oxygen-stratified lakes was found to be influenced by oxygen gradients, with Alphaproteobacterial methanotrophs preferring oxic water layers and Methylococcales methanotrophs thriving at and below the oxic-anoxic interface, showing distinct depth variation patterns not completely predictable by taxonomic classification. Genomic differences among Methylococcales methanotrophs explained their variable vertical depth patterns, with genetic adaptations for stress tolerance and motility at different depths.

Summary: Metagenomics is a powerful tool for assessing microbial communities in biological wastewater treatment by revealing the composition and function of microbial communities more effectively than traditional molecular methods. It can provide insights into the contribution of microbial diversity and metabolic diversity to processes such as biological removal of phosphorus and nitrogen, study of antibiotic resistance genes, and reduction of heavy metals by microbial communities.

Summary: In this study, ultrathin Bi2O2Se quantum dots with small size and strong visible fluorescence were synthesized using a top-down chemical approach. These quantum dots exhibited high optical band gap and fluorescence quantum yield in the green region, and were selective for detecting iron ions over a wide dynamic range with low detection limit. The mechanism of fluorescence and quenching induced by iron ions was investigated, and the synthesis method was proposed for potential applications in heavy metal ion sensing.

Summary: The study evaluated the impacts of hexavalent chromium (Cr) contamination on the microbiome, soil physicochemistry, and heavy metal resistome of a tropical agricultural soil. It found that Cr contamination led to a decrease in total organic matter content and a significant reduction in phosphorus, potassium, and nitrogen concentration. Heavy metals analysis revealed the decrease in concentrations of seven heavy metals in the contaminated soil. The study also showed significant shifts in the soil microbiome and heavy metal resistome, as well as alterations in soil physicochemistry.

Summary: This study found that knockout of the FTO gene in adipose tissue can alleviate hepatic steatosis caused by obesity and improve the expression levels of genes related to hepatic lipid metabolism. Further experiments demonstrated that FTO knockout increased the levels of IL-6 in adipose tissues and 3T3-L1 cells, and the increase in IL-6 inhibited the expression of lipolysis-related genes. Finally, both depletion of FTO in adipocytes and IL-6 supplementation led to increased expression of lipolysis genes in AML12 cells.

Summary: The application of organic fertilizer is an important measure for improving the quality of agricultural products and realizing sustainable development in agriculture. Research shows that large-scale farmers are more likely to apply organic fertilizer and increase the application intensity, while farmer heterogeneity also affects their organic fertilizer application behavior. Therefore, the government should encourage farmers to engage in moderate-scale management and promote the application of organic fertilizer through raising awareness, strengthening education and training, and providing financial support.

Summary: This study reveals the regulatory role of mRNA m(5)C modification in adipogenesis and myogenesis. Higher levels of mRNA m(5)C are associated with lower fat and higher muscle mass. m(5)C modification inhibits lipid accumulation and promotes myogenic differentiation. YBX2 and SMO are identified as m(5)C targets, which are involved in the regulation of adipogenesis and myogenesis through ALYREF-mediated subcellular localization.

Summary: This paper presents a delay-locked loop (DLL) with multiple radiation-hardened techniques to mitigate the effects caused by single-event transient (SET). The proposed techniques include a radiation-hardened charge pump (RH-CP) and a radiation-hardened voltage-controlled delay line (RH-VCDL). Furthermore, a lock detection module (LDM) and a SET correction module (SCM) are designed to prevent errors such as inverted lock error and missing pulses at the output of DLL.

Summary: In this study, it was found that the combination of Shenmai injection (SMI) and cisplatin enhanced cisplatin-induced apoptosis in non-small cell lung cancer (NSCLC) cells by regulating Mfn2-dependent mitochondrial dynamics. This sensitization effect was demonstrated through increased mitochondrial fusion, upregulation of Mfn2, downregulation of ATAD3A, reduced mitochondrial mass, and enhanced apoptosis signaling pathways, ultimately overcoming cisplatin resistance in lung adenocarcinoma cells.
