摘要：Ecologists and conservation scientists have long acknowledged that biodiversity data reflect legacies of social inequity (see the figure). Although the ramifications of these disparities were easy to dismiss when the application of large-scale biodiversity data was limited to academic biogeography and theoretical conservation prioritizations, the stakes have changed. Biodiversity data carry more influence than ever before (1), guiding the implementation of massive multilateral commitments and ...

摘要：In recent years, the research community has become increasingly concerned with issues involving the manipulation of images in scientific papers. Some of these alterations-involving images from experimental techniques such as microscopy, flow cytometry, and western blots-are inadvertent and may not change the conclusions of papers. But in rare cases, some are done deliberately to mislead readers. Image sleuths who can detect these alterations, like the scientific integrity consultant Elisabeth ...

摘要：Catalytic methods to couple alkene and amine feedstocks are valuable in synthetic chemistry. The direct carbonylative coupling of alkenes and amines holds promise as a perfectly atom-economical approach to amide synthesis, but general methods remain underdeveloped. Herein, we report an alkene hydroaminocarbonylation catalyzed by unmodified, inexpensive cobalt carbonyl under mild conditions and low pressure promoted by light. Silane addition after the reaction enables sequential cobalt-catalyze...
