• Clustered protocadherin cis- interactions are required for combinatorial cell-cell recognition underlying neuronal self- avoidance AI翻译

  摘要：In the developing human brain, only 53 stochastically expressed clustered protocadherin (cPcdh) isoforms enable neurites from individual neurons to recognize and self- avoid while simultaneously maintaining contact with neurites from other neurons. Cell assays have demonstrated that self-- recognition occurs only when all cPcdh isoforms perfectly match across the cell boundary, with a single mismatch in the cPcdh expression profile interfering with recognition. It remains unclear, however, how...
• Structural color in the bacterial domain: The ecogenomics of a 2-dimensional optical phenotype AI翻译

  摘要：Structural color is an optical phenomenon resulting from light interacting with nanostructured materials. Although structural color (SC) is widespread in the tree of life, the underlying genetics and genomics are not well understood. Here, we collected and sequenced a set of 87 structurally colored bacterial isolates and 30 related strains lacking SC. Optical analysis of colonies indicated that diverse bacteria from at least two different phyla ( Bacteroidetes and Proteobacteria) ) can create ...
• Private management of African protected areas improves wildlife and tourism outcomes but with security concerns in conflict regions AI翻译

  摘要：Protected areas can conserve wildlife and benefit people when managed effectively. African governments increasingly delegate the management of protected areas to private, nongovernmental organizations, hoping that private organizations' significant resources and technical capacities actualize protected areas' potential. Does private sector management improve outcomes compared to a counterfactual of government management? We leverage the transfer of management authority from governments to Afri...
• The Black Lives Matter movement mitigates bias against racial minority actors AI翻译

  摘要：Watching movies is among the most popular entertainment and cultural activities. How do viewers react when a movie sequel increases racial minority actors in the main cast (minority increase)? On the one hand, such sequels may receive better evaluations if viewers appreciate racially inclusive casting for its novel elements (the value- in-- diversity perspective) and moral appeal (the fairness perspective on diversity). On the other hand, discrimination research suggests that if viewers harbor...
• Global decarbonization potential of CO2 2 mineralization in concrete materials AI翻译

  摘要：CO2 2 mineralization products are often heralded as having outstanding potentials to reduce CO2- eq. 2- eq. emissions. However, these claims are generally undermined by incomplete consideration of the life cycle climate change impacts, material properties, supply and demand constraints, and economic viability of CO2 2 mineralization products. We investigate these factors in detail for ten concrete-- related CO2 2 mineralization products to quantify their individual and global CO2- eq. 2- eq. e...
• Kinesin-1-transported liposomes prefer to go straight in 3D microtubule intersections by a mechanism shared by other molecular motors AI翻译
  作者：Bensel, Brandon M.; Previs, Samantha Beck; Bookwalter, Carol; Trybus, Kathleen M.; Walcott, Sam; Warshaw, David M.

  摘要：Kinesin-1 ensembles maneuver vesicular cargoes through the three-dimensional (3D) intracellular microtubule (MT) network. To define how such cargoes navigate MT intersections, we first determined how many kinesins from an ensemble on a lipid-based cargo simultaneously engage a MT, and then determined the directional outcomes (straight, turn, terminate) for liposome cargoes at perpendicular MT intersections. Run lengths of 350-nm diameter liposomes decorated with up to 20, constitutively active...

  摘要：Transport networks, such as vasculature or river networks, provide key functions in organisms and the environment. They usually contain loops whose significance for the stability and robustness of the network is well documented. However, the dynamics of their formation is usually not considered. Such structures often grow in response to the gradient of an external field. During evolution, extending branches compete for the available flux of the field, which leads to effective repulsion between...
• Orthogonality of sensory and contextual categorical dynamics embedded in a continuum of responses from the second somatosensory cortex AI翻译

  摘要：How does the brain simultaneously process signals that bring complementary information, like raw sensory signals and their transformed counterparts, without any disruptive interference? Contemporary research underscores the brain's adeptness in using decorrelated responses to reduce such interference. Both neurophysiological findings and artificial neural networks support the notion of orthogonal representation for signal differentiation and parallel processing. Yet, where, and how raw sensory...

  摘要：Although the formation of new walls during plant cell division tends to follow maximal tensile stress direction, analyses of individual cells over time reveal a much more variable behavior. The origin of such variability as well as the exact role of interphasic micro- tubule behavior before cell division have remained mysterious so far. To approach this question, we took advantage of the Arabidopsis stem, where the tensile stress pattern is both highly anisotropic and stable. Although cortical...
