  摘要：Long-duration space missions expose crews to extreme psychological and social stressors due to prolonged isolation and confinement. To examine how such conditions impact individual and team functioning, we studied a 10-mo Antarctic overwintering mission at Concordia Station, an analog for spaceflight, using self-report measures and wearable proximity sensors. Twelve crew members were assessed at four time-points. Results revealed a progressive increase in feelings of loneliness and conflict, w...

  摘要：Endogenous bioelectric currents regulate development and regeneration, but their influence on organismal longevity and stem cell-mediated repair is not well understood. We demonstrate that a brief, clinically safe pulse of electrical current (PEC) produces lasting rejuvenation in the colonial chordate Botryllus schlosseri. In this species where all differentiated tissues are replaced weekly and progenitor populations mediate the weekly de novo generation of new organs, organismal aging is dire...
• Reading ability in both deaf and hearing adults is linked to neural representations of abstract phonology derived from visual speech AI翻译

  摘要：Reading is central to academic and vocational success. Some deaf children face reading challenges due to limited access to spoken or signed language. Robust phonological representations are key to reading development in hearing children. Spoken language phonology may be one of many contributors to reading development in deaf children. Indeed, speechreading ability correlates with reading skill in both deaf and hearing individuals, suggesting it is linked to reading development regardless of he...

  摘要：Individuals are motivated to increase their social status. To succeed in this pursuit, people must track information about others in their social sphere, monitor group norms, and adjust their behavior strategically. This study employed functional MRI and ecological momentary assessment methods in a sample of 92 college students belonging to 9 social groups to elucidate the neural mechanisms underlying these processes and their relationship to conformity in the context of alcohol use. When youn...
• Plants tolerate substantial rates of plastid mistranslation via regulated proteostasis AI翻译

  摘要：In bacteria, protein mistranslation can improve stress tolerance. Mitochondria and plastids evolved from bacteria and use a prokaryotic-type expression machinery to synthesize proteins. Interestingly, fungi and animal mitochondria are highly sensitive to mistranslation, which for instance manifests in lethal mitochondrial cardiomyopathy disorder. The response in plant cells is unknown. Glutaminyl-transfer RNAs (Gln-tRNAGln) of bacteria and endosymbiotic organelles are synthesized indirectly. I...
• Genome evolution through polyploidy: Enhancing plant stress resilience in agriculture AI翻译
  作者：Edger, Patrick P.; Body, Melanie J. A.; De Donno, Sonia; Platts, Adrian E.; Wang, Jianrong; Jiang, Jiming

  摘要：Polyploidy, also known as whole genome duplication, is a major evolutionary force in plants, driving diversification and the generation of novel phenotypic variation, including superior abiotic and biotic stress tolerance. The enhanced stress resilience observed in certain polyploids is hypothesized to arise from dynamic epigenetic and genetic changes, including variations in gene content and cis-regulatory elements (CREs), that emerge following polyploidization. These changes directly impact ...

  摘要：Major depressive disorder (MDD) is characterized by symptom heterogeneity and sex differences in prevalence. To gain insight into these sex differences, we utilized the subchronic variable stress paradigm (SCVS) in which female mice are susceptible, while males are behaviorally resilient. We used the Four Core Genotypes mice to differentiate between sex chromosome complement (XX vs. XY) and gonad type (ovaries vs. testes) in stress susceptibility, uncoupling these factors by removing the teste...

  摘要：Long-term potentiation (LTP) is a lasting form of synaptic plasticity that can persist for hours or even days. It is associated with structural changes in both the presynaptic terminal and the postsynaptic spine. Presynaptically, the number and distribution of synaptic vesicles (SVs) affect synaptic efficacy. How the functional changes in synaptic efficacy after the induction of LTP are mirrored by identifiable structural alterations in the SV cluster is not fully understood. Here, we interrog...
