摘要：Ocean acidification caused by increasing anthropogenic CO2 is expected to impact marine phytoplankton productivity, yet the extent and even direction of these changes are not well constrained. Here, we investigate the responses of phytoplankton community composition and productivity to acidification across the western North Pacific. Consistent reductions in primary production were observed under acidified conditions in the North Pacific Subtropical Gyre and the northern South China Sea, wherea...

摘要：Low-energy excitations play a key role in all condensed-matter systems, yet there is limited understanding of their nature in glasses, where they correspond to local rearrangements of groups of particles. Here, we introduce an algorithm to systematically uncover these excitations up to the activation energy scale relevant to structural relaxation. We use it in a model system to measure the density of states on a scale never achieved before, confirming that this quantity shifts to higher energy...

摘要：Stem cells possess inherent properties of self- renewal and differentiation, and thus hold significant promise for regenerating damaged tissues or replacing lost cells. Unless their therapeutic effects are solely mediated by paracrine, transplanted stem cells need to be highly plastic to adapt to the host tissue environment and differentiate into constituent tissue- specific cells for tissue repair. Stem cells used in current cell- based therapies either have limited differentiation potential ...

摘要：Recurrent implantation failure (RIF) is a devastating condition that leaves many undergoing fertility treatment childless. The human endometrium is receptive to a blastocyst for a brief period, the window of implantation. Critical knowledge underpinning biological processes leading to RIF, essential for effective treatment, is lacking. We employed spatial transcriptomics to define region- and cell- type- specific differences in endometrial gene expression in luteinizing hormone timed biopsies ...

摘要：Autocratic governments around the world use clandestine propaganda campaigns to influence the media. We document a decade-long trend in China toward the planting of government-authored articles in party and commercial newspapers. To examine this phenomenon, we develop an approach to identifying scripted propaganda-the coerced reprinting of lightly adapted government-authored articles in newspapers- that leverages the footprints left by the government when making media interventions. We show th...

摘要：CXCR4 (CXC chemokine receptor type 4), a member of the G protein-coupled receptor superfamily, plays a role in cell migration and functions as a coreceptor for HIV entry. Molecular therapeutics targeting CXCR4 have been under intensive investigation. To date, only two small-molecule antagonist drugs targeting CXCR4, plerixafor (AMD3100) and mavorixafor (AMD070), have been approved. Here, we present the high-resolution structures of CXCR4 complexed with AMD3100 and AMD070, as well as a small-mo...

摘要：to detect and measure in labor markets. We present evidence from a field experiment (N = 1,128) conducted in Australia on a major gig economy platform that allows users to outsource everyday tasks. By manipulating both the sexual orientation of job posters (gay vs. straight male) and physical proximity requirements of tasks (inside vs. outside the home), we identify discrimination against gay profiles and demonstrate a specific mechanism for its emergence: physical proximity. Gay profiles rece...
