Engineering the Link: From Genome Interaction Maps to Functional Insight
Advanced Biology, EarlyView.Advances in chromosome conformation capture have revealed the genome's 3D organization, yet its causal impact on gene regulation remains elusive. This review highlights emerging genome‐engineering tools ‐ zinc fingers, TALEs, and CRISPR‐Cas9 ‐ that enable targeted manipulation of chromatin loops to dissect structure–function relationships. It discusses

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
