Seasonal Dynamics of the Bacterial Community in Lake Urmia, a Hypersaline Ecosystem.

Lake Urmia is one of the world's most unique and hypersaline aquatic ecosystems. The aim of this study was to investigate the diversity, abundance and frequency of these microorganisms in water samples from the eastern regions of the lake over four seasons. Amplicon sequencing for the 16S rRNA gene was performed to examine bacterial communities in the samples.

Integrative bioinformatics approaches reveal key hub genes in cyanobacteria: insights from Synechocystis sp. PCC 6803 and Geminocystis sp. NIES-3708 under abiotic stress conditions.

Background: Cyanobacteria, particularly Synechocystis sp. PCC 6803, serve as model organisms for studying acclimation strategies that enable adaptation to various environmental stresses. Understanding the molecular mechanisms underlying these adaptations provides insight into how cells adjust gene expression in response to challenging conditions.

CRISPR-Cas-mediated adaptation of Thermus thermophilus HB8 to environmental stress conditions.

Bacteria experience a continual array of environmental stresses, necessitating adaptive mechanisms crucial for their survival. Thermophilic bacteria, such as Thermus thermophilus, face constant environmental challenges, particularly high temperatures, which requires robust adaptive mechanisms for survival. Studying these extremophiles provides valuable insights into the intricate molecular and physiological processes used by extremophiles to adapt and survive in harsh environments.

Optimal integration of photovoltaic sources and capacitor banks considering irradiance, temperature, and load changes in electric distribution system.

This paper introduces the Efficient Metaheuristic BitTorrent (EM-BT) algorithm, aimed at optimizing the placement and sizing of photovoltaic renewable energy sources (PVRES) and capacitor banks (CBs) in electric distribution networks. The main goal is to minimize energy losses and enhance voltage stability over 24 h, taking into account varying load profiles, solar irradiance, and temperature effects. The algorithm is rigorously tested on standard distribution networks, including the IEEE 33, IEEE 69, and ZB-ALG-Hassi Sida 157-bus systems.

Healthiness, appearance, or fashion? The drivers behind the sushi popularity in Italy.

Italy is witnessing an unprecedented success for sushi even if Italian consumers have a historical reluctance towards eating raw fish. It is important to understand what is behind this major shift in preferences, since it may set an example for the process of adoption of global products and/or diets. To this aim, we investigated which food motives drive sushi consumption (i.
