The conundrum of Shiga toxin-producing Escherichia coli O157:H7 persistence: Evidence for locally persistent lineages

This study challenges the notion that Shiga toxin-producing *Escherichia coli* O157:H7 does not persist at the farm level by identifying 15 locally persistent lineages in Minnesota that have endured for up to 8.6 years and account for over a third of reported cases, thereby highlighting the critical role of ecosystem-level persistence in the disease burden.

Hypermutability of integrated sequences of viral origin in a Chlorarachniophyte

A mutation accumulation study in the marine phytoplankton *Bigelowiella natans* reveals that integrated viral sequences undergo extreme, regulated hypermutation characterized by T/A-to-C/G transitions on TpA dinucleotides, suggesting the existence of a conserved eukaryotic immune system that targets invading DNA through localized genome editing.

A segmental duplication-mediated deletion leads to neocentromere formation in orangutans

This study reveals that a segmental duplication-mediated deletion of a 3.6 Mbp region on orangutan chromosome 10 removed the canonical centromere's higher-order repeat array, triggering the formation of a neocentromere and demonstrating the remarkable plasticity of centromere identity through structural variation and epigenetic reprogramming.

Flanking DNA sequences determine DNA methylation maintenance in proliferation, cancer and aging

This study reveals that the intrinsic sequence preference of the DNMT1-UHRF1 complex for specific flanking DNA hexanucleotides dictates the stability of CpG methylation during cell division, thereby driving the cumulative loss of methylation that serves as a molecular marker for biological aging and cancer progression.
