Single Nerve Cord Revealed as Ancestor of Ecdysozoan Nervous Systems
Neuroscience News - 10 Jan 2025 23:15A study analyzing Cambrian fossils uncovered that the ancestral ecdysozoan likely had a single ventral nerve cord, challenging long-standing views about the evolution of these structures. Fossil... impressions from early Scalidophora species reveal similarities to modern priapulid nerve cords, supporting the single-cord hypothesis. This finding suggests that paired nerve cords in arthropods, kinorhynchs, and loriciferans evolved independently, linked to body segmentation and movement complexity.
Delayed Brain Maturation Links Genetics and Eating Disorders

Physicist introduces percolation model to explain word puzzle solving behavior
Phys.org - 10 Jan 2025 16:17Alexander Hartmann, a physicist at the University of Oldenburg, in Germany, has introduced a new model to explain a common word puzzle phenomenon. In his paper published in the journal Physical Review... E, he suggests that instances where a puzzle solver experiences a sudden insight that allows them to begin finding solutions that seemed hidden are similar in some respects to the type of percolation seen when water percolating through a teabag suddenly makes its way out of the bottom of the bag. He has developed what he describes as a percolation model for word puzzles.
