Migration is an essential characteristic of cells that occurs during many physiological and pathological processes. Astrocytes represent the most abundant cell type in the adult central nervous system (CNS), that play a crucial role in various functions such as guiding and supporting neuronal migration during development and maintaining brain homeostasis at adulthood. Astrocytes specifically synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN).

- The study examines the variety of halophilic archaea in the geothermal waters of southern Tunisia, important for irrigation in arid regions.
- Three types of samples—water, sediment, and halite-soil crust—were collected from two geothermal springs and analyzed using advanced DNA sequencing techniques.
- Results indicated a shared presence of 20 out of 33 genera between the sources, with unique genera identified, suggesting these organisms can thrive in fluctuating conditions away from geothermal sites.
Article Synopsis
- The Sterile Insect Technique (SIT) uses sterilized male pests to control populations without harming the environment, by mating them with wild females who then don't produce offspring.
- Recent studies show that adding probiotics to the diet of medflies (Ceratitis capitata) significantly improves their quality, which could enhance SIT's effectiveness.
- An analysis of medflies showed that probiotic supplementation altered their metabolomic profile, leading to the identification of key metabolites that could play roles in pest control strategies.*
This study aimed to investigate the antibacterial activity of essential oils from Cupressus sempervirens (CSEO) and Eucalyptus globulus (EGEO) against clinical isolates of colistin-resistant E. coli and methicillin-resistant M. sciuri recovered from diseased food-producing animals in Tunisia.

These phototrophic organisms release organic exudates into their immediate surroundings, attracting heterotrophic bacteria that contribute to the diversity and functioning of these ecosystems. In this study, the microbial mats from a hydrothermal pool in the Ksar Ghilane oasis in the Grand Erg Oriental of the Desert Tunisia were collected to obtain cyanobacterial cultures formed by single cyanobacterial species.
