- Mutations in GBA1 cause Gaucher disease and are the most important genetic risk factor for Parkinson’s disease. However, analysis of transcription at this locus is complicated by its highly homologous pseudogene, GBAP1. We show that >50% of short RNA-sequencing reads mapping to GBA1 also map to GBAP1. Thus, we used long-read RNA sequencing in the human brain, which allowed us to accurately quantify expression from both GBA1 and GBAP1. We discovered significant differences in expression compared to short-read data and identify currently unannotated transcripts of both GBA1 and GBAP1. These included protein-coding transcripts from both genes that were translated in human brain, but without the known lysosomal function—yet accounting for almost a third of transcription. Analyzing brain-specific cell types using long-read and single-nucleus RNA sequencing revealed region-specific variations in transcript expression. Overall, these findings suggest nonlysosomal roles for GBA1 and GBAP1 with implications for our understanding of the role of GBA1 in health and disease.

- Controversy exists regarding the processes involved in creative thinking with the Remote Associates Test (RAT) and the Compound Remote Associates Test (CRAT). We report three experiments that aimed to shed light on the component processes underpinning CRAT performance by using the mere presence of task-irrelevant sound as a key theoretical tool. Experiments 1 and 2 revealed that CRAT performance was impaired relative to a quiet condition by the presence of sequences of changing letters and tones, respectively. In both experiments a non-changing sound (a repeated letter or a repeated tone) produced no disruption relative to quiet. Experiment 3 established that additional disruption was engendered by having to ignore meaningful speech as compared to meaningless speech. These experiments demonstrate that both semantic activation and subvocalisation are important determinants of successful creative thinking with CRAT problems. We suggest that semantic activation underpins solution-generation processes whereas subvocalisation underpins solution-evaluation processes.

- Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural dines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale.
