Wildfires impact on PM concentration in galicia Spain.

Wildfire intensity and severity have been increasing in the Iberian Peninsula in recent years, particularly in the Galicia region, due to rising temperatures and accumulating drier combustible vegetation in unmanaged lands. This leads to substantial emissions of air pollutants, notably fine particles (PM), posing a risk to public health. This study aims to assess the impact of local and regional wildfires on PM levels in Galicia's main cities and their implications for air quality and public health.

Modelling the structures of frameshift-stimulatory pseudoknots from representative bat coronaviruses.

Coronaviruses (CoVs) use -1 programmed ribosomal frameshifting stimulated by RNA pseudoknots in the viral genome to control expression of enzymes essential for replication, making CoV pseudoknots a promising target for anti-coronaviral drugs. Bats represent one of the largest reservoirs of CoVs and are the ultimate source of most CoVs infecting humans, including those causing SARS, MERS, and COVID-19. However, the structures of bat-CoV frameshift-stimulatory pseudoknots remain largely unexplored.

Crop Type Maps for Operational Global Agricultural Monitoring.

Crop type maps identify the spatial distribution of crop types and underpin a large range of agricultural monitoring applications ranging from early warning of crop shortfalls, crop condition assessments, production forecasts, and damage assessment from extreme weather, to agricultural statistics, agricultural insurance, and climate mitigation and adaptation decisions. Despite their importance, harmonized, up-to-date global crop type maps of the main food commodities do not exist to date. To address this critical data gap of global-scale consistent, up-to-date crop type maps, we harmonized 24 national and regional datasets from 21 sources covering 66 countries to develop a set of Best Available Crop Specific masks (BACS) over the major production and export countries for wheat, maize, rice, and soybeans, in the context of the G20 Global Agriculture Monitoring Program, GEOGLAM.

Disassembly of microtubules by intense terahertz pulses.

The biological effects of terahertz (THz) radiation have been observed across multiple levels of biological organization, however the sub-cellular mechanisms underlying the phenotypic changes remain to be elucidated. Filamentous protein complexes such as microtubules are essential cytoskeletal structures that regulate diverse biological functions, and these may be an important target for THz interactions underlying THz-induced effects observed at the cellular or tissue level. Here, we show disassembly of microtubules within minutes of exposure to extended trains of intense, picosecond-duration THz pulses.

Biodiscovery of antibacterial constituents from the endolichenic fungi isolated from .

A total of nine endolichenic fungi were isolated from the foliose lichen (Nyl.) Hale. Of the nine endolichenic fungi, three taxa (, , ) showed antibacterial activities as determined by the disk diffusion assay against ESKAPE bacterial pathogens.

[Variability in the cesarean ratio and indications for the procedure among Spanish hospitals].

Objective: To describe variability in the cesarean ratio and indications for this procedure in women with and without a previous cesarean section.

Methods: We conducted a cross-sectional study of 111 hospitals (year 2010) categorized in six levels. Ten groups of indications for cesarean section were developed.
