Summary: The bacterial community in Antarctic bioaerosols is dominated by Proteobacteria, showing low alpha-diversity but significant spatial and temporal variabilities. These bacteria are potentially transported from terrestrial, marine, and Antarctic polar sources through long-range transport and sea-air exchange pathways. The composition of bacterial community is significantly influenced by factors such as wind speed, temperature, and organic carbon, while bacterial richness and diversity do not differ significantly under different weather conditions.

Summary: This study analyzed the temporal variation of airborne dust concentrations in the Mogao Grottoes, Northwest China, and found that real-time dust concentration data for dust storms in arid regions are still limited. The study revealed a gradual decrease in dust concentrations from February to October, with extreme values occurring mainly in February, March, and April. In typical dust storms, the maximum real-time concentrations were recorded, highlighting the high dust concentrations in the Mogao Grottoes due to the dry climate, windy season, and sufficient dust sources in the surrounding environment.

Summary: The Mogao Grottoes, a UNESCO World Cultural Heritage site, have been affected by microbial colonization and deterioration of the wall paintings, resulting in the appearance of black spots and microbial biomasses. Next-generation sequencing and microscopy were used to identify the microbial community responsible for the biodeterioration. Rhodococcus and Ralstonia were found to be the dominant bacteria, while Aspergillus species were the predominant fungi in the black spots and microbial biomasses. Radioactive carbon-14 dating suggested that the original mural was painted during the Five Dynasties and Ten Kingdoms period, with repainting most likely occurring during the Song Dynasty. The outbreak of indigenous microbes on the wall paintings was likely initiated by earthen plaster preparation or heavy rainfall combined with a leaky roof.

Summary: This study analyzed the bacterial communities in airborne particulate samples from around the world and found that they have a biogeographic pattern and interact with surface environments. While the total abundance of airborne bacteria is lower than other habitats, the number of bacterial taxa is comparable to the hydrosphere and is highest in midlatitude regions. The structure of the airborne bacterial community is easily perturbed and influenced by surface microbiomes and atmospheric conditions, particularly in urban areas. These findings provide valuable insights for predicting microbial responses and health impacts in different environments.

Summary: Although research on the natural ventilation of single-sided buildings is progressing, research on the natural ventilation of the Mogao Grottoes, which have special shapes and structures, is relatively limited. The purpose of this paper is to develop a correlation for calculating the natural ventilation rates of such grottoes. Field experiments were carried out on two typical caves to measure their meteorological parameters and natural ventilation rates to verify the validity of the proposed correlation. The results show that our correlation has good reliability and stability when predicting the natural ventilation rates of the caves.

Summary: This study examined the culturable bacterial diversity in the subsurface of the Surtsey island in Iceland, which represents newly-formed oceanic crust. A total of 195 bacterial isolates were cultivated and identified, with six different clades identified. The isolated strains were closely related to species found in soil, seawater, and hydrothermal sites. Comparison with culture-independent methods revealed that only a small fraction of the bacterial diversity was cultivated, highlighting the importance of both culture-dependent and -independent approaches in understanding extreme volcanic environments.

Summary: B1L regulates lateral root initiation in Arabidopsis by mediating PIN recycling via exocytic vesicle trafficking. The b1l mutants exhibited increased lateral root primordium initiation, resulting in a higher number of lateral roots. The auxin signal was also stronger in the stage I lateral root primordia of b1l mutants. B1L interacts with the exocyst and is involved in regulating PIN exocytosis, thereby affecting polar auxin transport and lateral root development.

Summary: Afforestation can significantly increase carbon sinks in terrestrial ecosystems and slow down global warming. This study used eddy correlation method to measure carbon and water fluxes and environmental factors in two artificial forests in the dryland of Northwest China. Results showed that the Larix principis-rupprechtii forest ecosystem had higher water use efficiency, light use efficiency, gross primary productivity, and ecosystem respiration compared to the Pinus tabulaeformis forest ecosystem. However, the P. tabulaeformis forest ecosystem had higher carbon sequestration efficiency. The CO2 and H2O fluxes in the L. principis-rupprechtii forest ecosystem were more sensitive to environmental factors, and the RECO was more sensitive to temperature changes.
