  摘要：to and precisely follow very fast cycle-by-cycle fluctuations in the phase of sounddriven cochlear vibrations. Yet, the perceptual role of this temporal fine structure experimentally manipulate TFS cues without altering other perceptually relevant cues. Here, we circumnavigated this limitation by leveraging individual differences across 200 participants to systematically compare variations in TFS sensitivity to performance in a range of speech perception tasks. TFS sensitivity was assessed thr...

  摘要：In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature- dependent sex determination (TSD). In the red- eared slider turtle, Trachemys scripta, a TSD model species with a warm female promoting temperature (...
• Chromatin enables precise and scalable gene regulation with factors of limited specificity AI翻译

  摘要：Biophysical constraints limit the specificity with which transcription factors (TFs) can target regulatory DNA. While individual nontarget binding events may be low affinity, the sheer number of such interactions could present a challenge for gene regulation by degrading its precision or possibly leading to an erroneous induction state. Chromatin can prevent nontarget binding by rendering DNA physically inaccessible to TFs, at the cost of energy-consuming remodeling orchestrated by pioneer fac...

  摘要：The Qin and Western Han dynasties (221 BCE to 24 CE) represent an era of societal prosperity in China. However, due to a lack of high- resolution paleoclimate records it is still unclear whether the agricultural boost documented for this period was associated with more favorable climatic conditions. Here, multiparameter analysis of annually resolved tree- ring records and process- based physiological modeling provide evidence of stable and consistently humid climatic conditions during 270 to 7...
• An animal model recapitulates human hepatic diseases associated with GATA6 mutations AI翻译

  摘要：Heterozygotic GATA6 mutations are responsible for various congenital diseases in the heart, pancreas, liver, and other organs in humans. However, there is lack of an animal that can comprehensively model these diseases since GATA6 is essential for early embryogenesis. Here, we report the establishment of a gata6 knockout zebrafish which recapitulates most of the symptoms in patients with GATA6 mutations, including cardiac outflow tract defects, pancreatic hypoplasia/agenesis, gallbladder agene...
• PsDMAP1/PsTIP60-regulated H4K16ac is required for ROS- dependent virulence adaptation of Phytophthora sojae on host plants AI翻译

  摘要：Host plants and various fungicides inhibit plant pathogens by inducing the release of excessive reactive oxygen species (ROS) and causing DNA damage, either directly or indirectly leading to cell death. The mechanisms by which the oomycete Phytophthora sojae manages ROS stress resulting from plant immune responses and fungicides remains unclear. This study elucidates the role of histone acetylation in ROS- induced DNA damage responses (DDR) to adapt to stress. Mechanistically, the P. sojae DNA...

  摘要：Increasing soil organic carbon (SOC) in agricultural systems is a primary nature- based option for mitigating climate change, improving soil fertility, and ensuring food security. However, the consequences of global warming and increases in carbon inputs on cropland SOC stocks over the last few decades remain largely unknown, particularly in deeper soil layers. Here, by using repeated measurements, we reassess variations in SOC stocks across a 0 to 100 cm soil profile at the same locations in ...
• Synaptic integration and competition in the substantia nigra pars reticulata-An experimental and in silico analysis AI翻译

  摘要：The substantia nigra pars reticulata (SNr) is a primary output for basal ganglia signaling. It plays an important role in the control of movement, integrating inputs from upstream structures in the basal ganglia, before sending organized projections to a range of targets in the midbrain, brainstem, and thalamus. Here, we present a detailed in silico model of the mouse SNr, including its major afferent inputs. The electrophysiological and morphological properties of SNr neurons are characterize...
• The paradox of intervention: Resilience in adaptive multirole coordination networks AI翻译

  摘要：Complex adaptive networks exhibit remarkable resilience, driven by the dynamic interplay of structure (interactions) and function (state). While static-network analyses offer valuable insights, understanding how structure and function coevolve under external interventions is critical for explaining system-level adaptation. Using a unique dataset of clandestine criminal networks, we combine empirical observations with computational modeling to test the impact of various interventions on network...

  摘要：We investigate why work from home (WFH) rates vary so widely across countries using the Global Survey of Working Arrangements (G- SWA). Conducted in late 2024 and early 2025, G- SWA is the only harmonized international survey of remote work, covering 14,427 full- time, college- educated workers across 37 countries. Our analysis finds that cultural individualism accounts for 29 percent of the cross- country variation in WFH rates-more than any other single factor. Industry structure, population...
