The first insight into Acanthocephalus (Palaeacanthocephala) satellitome: species-specific satellites as potential cytogenetic markers.
Sci Rep

Department of Experimental Biology, Genetics Area, University of Jaén, Campus Las Lagunillas s/n, 23071, Jaén, Spain.
Acanthocephalan parasites are often overlooked in many areas of research, and satellitome and cytogenetic analyzes are no exception. The species of the genus Acanthocephalus are known for their very small chromosomes with ambiguous morphology, which makes karyotyping difficult. In this study, we performed the first satellitome analysis of three Acanthocephalus species to identify species- and chromosome-specific satellites that could serve as cytogenetic markers.

Background/objectives: The ~1.6 kb NBPF repeat units in neuroblastoma breakpoint family (NBPF) genes are specific to humans and are associated with cognitive capacity in higher primates. While the number of NBPF monomers/Olduvai sequences in humans is approximately 2-3 times greater than in great apes, the difference in copy number values of canonical NBPF 3mer Higher-order repeats (HORs)/Olduvai triplets between humans and great apes is substantially larger.

Article Synopsis
- The study investigates how neural representations involved in learning categories evolve as individuals gain experience through a prototype learning task.
- It finds that while activity in brain regions tied to habitual learning remains stable, regions related to goal-directed learning decrease in activation over time, indicating a shift in processing.
- Advanced training enhances the ability to decode category information in the intraparietal sulcus and develops category representations in the motor cortex and ventromedial prefrontal cortex, reflecting improved decision-making and memory for category structures.

In modern science, the exchange of scientific material between different institutions and collaborating working groups constitutes an indispensable endeavor. For this purpose, bacterial strains are frequently shipped to collaborators to advance joint research projects. Bacterial strains are usually safely shipped as cultures on solid medium, whereas the shipment of liquid cultures requires specific safety measures due to the risk of leakage.

Article Synopsis
- The wine industry is adopting more sustainable practices, but it's important to evaluate the environmental impact of the analytical methods used for wine analysis.
- A new tool called "Green Wine Analytical Procedure Evaluation" (GWAPE) has been developed to assess these methods, covering everything from sample collection to final results.
- GWAPE provides a structured evaluation that considers green chemistry principles and helps wineries analyze the environmental effects of their analytical processes, as demonstrated by its effective comparison of three standard methods for measuring sugars in wine.
