Exploring the Impact of RNU4‐2 Defects on Neurodevelopmental Disorders in a Korean Population

open access: yesClinical Genetics, EarlyView.
Among 15 450 Korean individuals, noncoding RNU4‐2 variants, primarily the recurrent de novo n.64_65insT, make up 0.72% of neurodevelopmental disorders. Modeling and RNA‐seq suggest U4/U6 disruption and abnormal 5′ splice‐site selection, supporting routine use of WGS analysis for reanalyzing unresolved cases. ABSTRACT Neurodevelopmental disorders (NDDs)

Evaluation of Catch Performance and Environmental Impact of Technical Gear Modifications for a More Sustainable Scallop Dredging Fishery

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions
