• From past, persisting, and consolidating ecologies of segregation to ecologies of repair AI翻译
  作者：Anguelovski, Isabelle; Connolly, James J. T.; Corbera, Esteve; Pellow, David N.; Hoover, Fushcia-Ann; Scott, Jacqueline L.; Hendricks, Marccus D.; Schell, Christopher J.
  摘要：Across the United States and Europe, urban and periurban spaces have historically been shaped by land dispossession and enclosure that systematically exclude marginalized, non-White communities from the benefits of society, including access to nature. These dynamics, which have played out and perdured over centuries as part of historic land dispossession and recent green racial capitalism, form the bedrock of contemporary urban segregation and socioecological inequalities. As a result, we see ...
• Housing tenure, climate resilience, and ecological segregation AI翻译
  作者：Gulsrud, Natalie M.; Garcia-Antunez, Oriol; Olafsson, Anton S.; Jensen, Marina Bergen
  摘要：A key challenge to ensuring no one is left behind in the green transition lies in the persistent segregation of urban populations and the unequal distribution of environmental costs and benefits. Residential segregation has long reinforced socioeconomic and racialized disparities, and climate change introduces new dimensions to these injustices as adaptation policies increasingly shift financial and environmental burdens onto marginalized communities. While housing plays a central role in shap...
• Nonperturbative nonlinear magnonics in a strongly driven antiferromagnet AI翻译

  摘要：Nonlinear dynamics govern a wide array of natural phenomena and are essential for understanding nonequilibrium behaviors in condensed matter systems. In magnetically ordered materials, magnons-the quanta of spin waves-exhibit intrinsic nonlinearities that are of great interest in fundamental research and practical applications. Despite progress in the nonlinear control of magnon modes in antiferromagnetic materials, the transition from perturbative to nonperturbative regimes of magnon coherenc...
• SelO functions as a tumor suppressor through AMPylating Cdk5rap3 AI翻译
  作者：Wu, Li; Wu, Jie; Xie, Wenqiang; Lu, Xue; Chen, Chunda; Zhang, Teng; Shen, Jie; Zhao, Yixiao; Chen, Lu; Li, Yeyi; Yu, Qiujing; Fu, Yuan; Wang, Ting
  摘要：Cell fate is governed by signaling pathways involving diverse protein modifications. However, how protein AMPylation mediates signal transduction in mammalian cells remains largely unexplored. We demonstrate that the protein adenylyltransferase, SELENOO (SelO), is induced by chemotherapy, and has clinical relevance in cancer. In mice, SelO knockout facilitates primary tumor development and metastasis. In cancer cells, the cytosolic fraction of SelO suppresses cell proliferation and migration. ...

• Structure-controlled quantum magnetotransport in Ba-Cu-As pnictide single crystals AI翻译

  摘要：The relationship between local coordination, framework connectivity, and lattice scattering, electronic structure, and quantum transport in complex pnictides remains poorly understood. Here, we show that Cu-As polyhedral architecture provides a structural route to tuning scattering and quantum magnetotransport in Ba-Cu-As pnictide single crystals. The clearest example is BaCu4As2, which undergoes a first-order transition near 225 K from a trigonal to a triclinic structure. This symmetry loweri...
• Alternative splicing of synaptotagmin 7 regulates oligomerization and short-term synaptic plasticity AI翻译

  摘要：Synaptic plasticity is crucial for learning and memory. The presynaptic calcium sensor synaptotagmin 7 (syt7) regulates aspects of short-term plasticity (STP), but the underlying mechanisms remain unclear. Here, we show that alternative splicing of the syt7 juxtamembrane linker acts as a molecular switch at both biochemical and functional levels. The alpha and beta variants undergo liquid-liquid phase separation to form condensates, while the gamma variant forms aggregates. Using iGluSnFR imag...
