摘要:In recent years the functionality of synthetic active microparticles has edged even closer to that of their biological counterparts. However, we still lack the understanding needed to recreate at the microscale key features of autonomous behavior exhibited by microorganisms or swarms of macroscopic robots. In this study, we propose a model for a three-dimensional deformable cellular composite particle consisting of self-propelled rod-shaped colloids confined within a flexible vesicle-represent...

摘要:Harnessing instabilities of multicomponent multistable structural assemblies can potentially lead to scalable and reversible functionalities, which can be enhanced by exploring frustration. For instance, standard Kresling origami cells exhibit nontunable intrinsic energy landscapes determined by their geometry and material properties, limiting their adaptability after fabrication. To overcome this limitation, we introduce frustration to enable fine-tuning of the energy landscape and resulting ...

摘要:Life thrives due to its remarkable ability to create complex structures through the self-assembly of proteins, nucleic acids, and other biomolecules. Achieving such complex assemblies with the same level of fidelity, reproducibility, and advanced functionality in synthetic systems, however, has remained a grand challenge. One outstanding problem is the presence of parasitic products and long-lived intermediate states that slow the reaction process and limit the yield of the final product. Biol...

摘要:Black carbon (BC) aerosols exacerbate air pollution and climate warming, but their climatic impacts and sources are poorly constrained by bottom-up emission inventories (EIs). China's Clean Air Action (CAA), which was launched in 2013, provides an excellent opportunity for investigating interannual variations in source contributions and validate the accuracy of EIs. Here, we present an 11-y (2008-2018) record of the BC concentration and its source-diagnostic radiocarbon (14C) and stable carbon...

摘要:How societies remember the dead can reveal what people value in life. We analyzed 38 million obituaries from the United States to examine how personal values are encoded in individual and collective legacies. Using Schwartz's theory of basic human values, we found that tradition and benevolence dominated legacy reflections, while values like power and stimulation appeared less frequently. Major cultural events-the terrorist attacks of September 11th, the 2008 financial crisis, and the COVID-19...

摘要:Environmental DNA (eDNA) is increasingly used for biodiversity monitoring, but validation of the spatial scale(s) at which eDNA reflects extant communities is scarce, particularly in tropical forests: the terrestrial biome with the most concentrated diversity on earth. We leveraged spatially explicit tree inventory data from the 16-ha Luquillo Forest Dynamics Plot (LFDP) in Puerto Rico to validate soil eDNA as a spatially explicit indicator of tree diversity/composition. Using a comprehensive ...

摘要:Despite extensive efforts, our understanding of the virulence factors contributing to oral biofilm formation-a hallmark of dental caries-remains incomplete. We present evidence that the specialized metabolism of the oral microbiome is a critical yet under-explored factor in oral biofilm formation. Through microbiome analysis, we identified a hybrid nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) encoding biosynthetic gene cluster that correlates with dental caries and is w...

摘要:The KRAS oncogene has been associated with many types of cancer, including pancreatic, lung, and colorectal. For decades, its gene products were thought to be undruggable. However, during the last decade, a large battery of KRAS inhibitors selective against specific mutations (KRASG12C and KRASG12D), panKRAS inhibitors active against all KRAS isoforms, or even panRAS inhibitors, capable of inhibiting the three members of the RAS family, have been developed. In mice, the Kras locus is essential...

摘要:Scientific institutions like funding agencies and journals rely on peer reviewers to select among competing submissions. How does the geographical diversity of reviewers affect which authors are selected? If reviewers typically favor submissions from their own countries, but reviewers from only some countries are well represented in the reviewer pool, this can create a geographical representation bias favoring authors from those well-represented countries. Using administrative data on 204,718 ...
