We investigated primary and secondary geometric isotope effects (H, D, T) on charge-inverted hydrogen bonds (CIHB) and dihydrogen bonds (DHB) using nuclear-electronic orbital density functional theory (NEO-DFT). The dianionic but electrophilic boron cluster [BH] served as a bonding partner, exhibiting a negatively polarized hydrogen atom in the BH bond. CIHB systems included interactions with Lewis acids (AlH, BH, GaH) and carbenes (CF, CCl, CBr), while DHBs were analyzed with NH, HF, HCl, and HBr.

As essential sources of vegetables, oilseeds, and forage, Brassica crops exhibit complex epigenetic regulation mechanisms involving histone modifications, DNA modifications, RNA modifications, noncoding RNAs, and chromatin remodelling. The agronomic traits and environmental adaptability of crops are regulated by both genetic and epigenetic mechanisms, while epigenetic variation can affect plant phenotypes without changing gene sequences. Furthermore, the impact of epigenetic modifications on plant phenotype has accelerated the crop breeding process.

A growing literature explores the representational detail of infants' early lexical representations, but no study has investigated how exposure to real-life acoustic-phonetic variation impacts these representations. Indeed, previous experimental work with young infants has largely ignored the impact of accent exposure on lexical development. We ask how routine exposure to accent variation affects 6-month-olds' ability to detect mispronunciations.

Background: Diverse correlations between structural brain abnormalities and the clinical feature of bulimia nervosa (BN) have been identified in previous observational studies.
Objective: To explore the bidirectional causality between BN and brain structural magnetic resonance imaging (MRI) phenotypes.
Methods: Genome-wide association studies (GWAS) of 2441 participants identified genetic variants associated with disordered eating and predicted BN, whereas UK Biobank 3D-T1 MRI data were used to analyze brain structural phenotypes.

Migration is widespread among animals but varies in its manifestation with differences in direction, distance and obligatory nature. Understanding the evolution of migration requires insight into not only the development of this behaviour but also the loss of it. Partial migration, where some individuals within a population migrate while others stay, provides a unique opportunity to identify the proximate factors determining migratory/resident behaviours.
