Clean energy adoption is crucial in combating climate change and crowdfunding, when aligned with investor preferences, can play a pivotal role in accelerating the clean energy transition. However, little is known about what drives crowdfunding investment decisions. This study employs a Fuzzy-set Qualitative Comparative Analysis (fsQCA) to examine 88 solar energy projects in Spain and Italy, identifying the key factors that inf...

Aims Carbon accumulation in terrestrial ecosystems is inherent to the vegetation development and ageing process. Primary productivity synthetize biomass which is constantly incorporated to soil. Vegetation community composition, and other ecological drivers, are known to mediate biomass production. However, links between forest developmental stage and ecological drivers of carbon stocks are unexplored. We address this topic un...

Clonal hematopoiesis, especially that of indeterminate potential (CHIP), has been associated with age-related diseases, such as those contributing to a more severe COVID-19. Four studies have attempted to associate CHIP with COVID-19 severity without conclusive findings. In the present work, we explore the association between CHIP and COVID-19 mortality. Genomic DNA extracted from peripheral blood of COVID-19 patients ( n = 24...

Many microorganisms produce and excrete acetoin (3‐hydroxy‐2‐butanone) when growing in environments that contain glucose or other fermentable carbon sources. This excreted compound can then be assimilated by other bacterial species such as pseudomonads. This work shows that acetoin is not a preferred carbon source of Pseudomonas putida , and that the induction of genes required for its assimilation is down‐modulated by differe...

Aims We studied the regeneration dynamics of woodlands and abandoned old fields in a landscape dominated by Quercus suber in its lower limits of rainfall and temperature. Two hypotheses were established: (1) regeneration of Quercus species is strongly favored by the presence of tree cover; and (2) growth of Q. suber is driven by the climatic variables that represent the lower ecological limit of its leading distribution edge....

Summary In an article in this issue of Environmental Microbiology, Segura et al . report the identification of an unusual global regulator in Novosphingobium sp. HR1a, a metabolically versatile bacterial strain isolated from the rhizosphere able to assimilate a wide range of polyaromatic hydrocarbons (PAHs). Physiological and transcriptomic assays suggest that this regulator, named PahT, activates the expression of genes invol...

When the soil bacterium Pseudomonas putida grows in a complete medium, it prioritizes the assimilation of preferred carbon sources, optimizing its metabolism and growth. This regulatory process is orchestrated by the Crc and Hfq proteins. The present work examines the changes that occur in metabolic fluxes when the crc gene is inactivated and cells grow exponentially in LB complete medium. Analyses were performed at three diff...

Summary Pseudomonas putida is a soil bacterium with a versatile and robust metabolism. When confronted with mixtures of carbon sources, it prioritizes the utilization of the preferred compounds, optimizing metabolism and growth. This response is particularly strong when growing in a complex medium such as LB. This work examines the changes occurring in P. putida KT2440 metabolic fluxes, while it grows exponentially in LB mediu...

Summary Metabolically versatile bacteria use catabolite repression control to select their preferred carbon sources, thus optimizing carbon metabolism. In pseudomonads, this occurs through the combined action of the proteins Hfq and Crc, which form stable tripartite complexes at target mRNAs, inhibiting their translation. The activity of Hfq/Crc is antagonised by small RNAs of the CrcZ family, the amounts of which vary accordi...
