Population structure and cultural geography of a folktale in Europe.

open access: yes, 2015
Despite a burgeoning science of cultural evolution, relatively little work has focused on the population structure of human cultural variation. By contrast, studies in human population genetics use a suite of tools to quantify and analyse spatial and ...

Co‐Selection of Low Cadmium Accumulation and High Yield During Tomato Improvement

open access: yesAdvanced Science, EarlyView.
This study finds that large‐fruited tomatoes accumulate less cadmium (Cd) compared to wild tomatoes and cherry tomatoes. This is because, during the improvement process of tomato, the low‐Cd allele LCT1A and the large fruit allele fw3.2T are closely linked, leading to a co‐selection event.

Blinded by the Lights. Improvisational Theater as a Method for Researching Regional Identities

open access: yesForum: Qualitative Social Research
We explore how improvisational (improv) theater can be used to illuminate the everyday performance of regional identity. This can help manage reactivity-related and counter-performative effects during qualitative research.

GmSop20 Functions as a Key Coordinator of the Oil‐To‐Protein Ratio in Soybean Seeds

open access: yesAdvanced Science, EarlyView.
This study investigates the seed oil‐to‐protein ratio as a comprehensive quality metric and identifies GmSop20 as a crucial regulatory gene through forward genetics methodologies. By integrating GmSop20 with superior haplotypes and using gene editing/overexpression, new strategies are provided for precisely tuning the seed oil‐to‐protein ratio, thereby

Megasphaera Elesdenii Dysregulates Colon Epithelial Homeostasis, Aggravates Colitis‐Associated Tumorigenesis

open access: yesAdvanced Science, EarlyView.
A fecal microbial meta‐analysis reveals that Megasphaera is highly abundant in the Asian population with IBD and CRC. M. elsdenii reshapes colonic immunity by triggering DC cell‐mediated Th1 and Th17 inflammation. M. elsdenii and M. elsdenii‐enriched microbiota exacerbate colonic inflammation and tumorigenesis in AOM/DSS mice.

Human Brain Cell‐Type‐Specific Aging Clocks Based on Single‐Nuclei Transcriptomics

open access: yesAdvanced Science, EarlyView.
Muralidharan and colleagues develop cell‐type‐specific transcriptomic aging clocks using single‐nucleus RNA sequencing of human post mortem prefrontal cortex samples. These clocks accurately predict age and identify distinct aging trajectories in specific brain cell types.
