(SINV-3) is a positive-sense, single-stranded RNA virus that infects the red imported fire ant, Buren. We report here the full genome (10,383 nucleotides) of an isolate infecting hybrid ants, which we have identified as SINV-3 hybrid.

In this work, we developed potential multifunctional agents to combat Alzheimer's disease. According to our strategy, fragments of tacrine and donepezil were merged in a unique hybrid structure. After successfully synthesizing the compounds, they were evaluated for their dual AChE/BuChE inhibitor potential and neuroprotector response using a glutamate-induced excitotoxicity model.

Cultivated meats are typically hybrids of animal cells and plant proteins, but their high production costs limit their scalability. This study explores a cost-effective alternative by hypothesizing that controlling the Maillard and lipid thermal degradation reactions in pure cells can create a meaty aroma that could be extracted from minimal cell quantities. Using spontaneously immortalized porcine myoblasts and fibroblasts adapted to suspension culture with a 1 % serum concentration, we developed a method to isolate flavor precursors via freeze-thawing.

To balance the convergence speed and solution diversity and enhance optimization performance when addressing large-scale optimization problems, this research study presents an improved ant colony optimization (ICMPACO) technique. Its foundations include the co-evolution mechanism, the multi-population strategy, the pheromone diffusion mechanism, and the pheromone updating method. The suggested ICMPACO approach separates the ant population into elite and common categories and breaks the optimization problem into several sub-problems to boost the convergence rate and prevent slipping into the local optimum value.

Biological invasions pose substantial threats to global biodiversity, agriculture, and ecological stability. Among these, intraspecific cryptic invasions, characterized by the spread of nonnative genotypes within a species, present unique challenges for detection and management. Despite the well-documented influence of invasive ants on ecosystems, instances of intraspecific cryptic ant invasions have rarely been documented.
View Article and Find Full Text PDFA taxonomic revision of the Palaearctic species of the ant genus Tapinoma Emery 1861 is provided. Due to the extreme rarity of discernable characters, the female castes of 64% of the species are not separable by primary visual perception of an expert and are thus truly cryptic. The main working rationale of the revision is Numeric Morphology-Based Alpha-Taxonomy (NUMOBAT) with formation of species hypotheses largely based on exploratory data analyses and checking these hypotheses by discriminant analysis.
