  摘要：The expansion of commodity agriculture into tropical forests leads to major social-ecological impacts. Yet little is known about where and how the capitalized actors driving this expansion interact with smallholders, particularly where smallholders live inside the forest. Two alternative outcomes of their interactions on deforestation are plausible: accelerated deforestation as all actors compete for land (i.e., land rush hypothesis) or, alternatively, slower deforestation as actors hinder eac...

  摘要：Abdominal ultrasound has emerged as a noninvasive modality with immunomodulatory potential. Although its anti-inflammatory effects have been demonstrated in various disease models, the underlying mechanisms remain unclear. Previous studies suggest that ultrasound promotes anti-inflammatory macrophage polarization via alpha 7 nicotinic acetylcholine receptor (alpha 7nAChR) signaling in the spleen. However, the upstream events initiating this response have not been elucidated. Here, we demonstra...

  摘要：Doping to control carrier (electron or hole) transport is foundational to modulate the properties of semiconductors, enabling the development of homojunctions and heterodominance, both cations and anions in electrolytes are mobile, which is undesirable for many applications. Here, we report a universal strategy to dope electrolytes such that the ion transport can be unipolar by incorporating electroactive polymers within hydrogels that interact discriminately with one type of ion via redox and...
• Social information creates self-fulfilling prophecies in judgments of pain, vicarious pain, and cognitive effort AI翻译

  摘要：Expectations can shape perception and potentially lead to self-fulfilling prophecies such as placebo effects that persist or grow over time. Nonetheless, whether and how unreinforced and unconditioned social cues (i.e., suggestions about future experiences that have not been reinforced with reward or punishment) can create and sustain such effects is unknown. We conducted a set of experiments in which participants (N = 111) experienced stimuli eliciting somatic pain (heat), vicarious pain (vid...
• Global stratospheric methane loss from satellite observations AI翻译

  摘要：Stratospheric CH4 oxidation represents both an important sink in the global CH4 budget and a major source of stratospheric water vapor and hydrogen radicals, exerting strong influences on global climate and ozone chemistry. Yet, the magnitude of stratospheric CH4 chemical loss remains highly uncertain, with previous estimates largely relying on chemistry-climate models (CCMs). Here, we present an observationally based estimate of stratospheric CH4 loss (L-STR), derived from the CH4 diabatic fl...
• Parasitic castration by a viral protein tyrosine phosphatase targeting the host cell cycle checkpoint protein Rad9A AI翻译

  摘要：Parasitic castration is a widespread strategy where parasites hijack host reproductive resources, yet the key molecular mechanisms driving this phenomenon remain poorly understood. Here, we reported that parasitization by the parasitic wasp Cotesia vestalis triggers apoptosis-mediated castration in the larval testes of its lepidopteran host, Plutella xylotella. Such a phenomenon was mediated by CvBV_22-9, a testis-enriched protein tyrosine phosphatase (PTP) encoded by Cotesia vestalis bracovir...

  摘要：The self-assembly of enzyme proteins on 2D nanomaterials has enabled the construction and functional control of viable biochemical pathways. However, enzymatic cascades, which combine essential components of the photosynthetic and respiratory electron transport chains in tandem, have thus-far remained elusive. Herein, we have investigated a galvanic biohybrid nanosystem coupling photosystem I and cytochrome c oxidase on the surface of graphene oxide nanosheets in colloidal suspension. The orie...
• Gradience as a cognitive principle for evaluating numerical notations AI翻译
  作者：Chrisomalis, Stephen
  作者单位：Wayne State University
  摘要：More than 100 historically, archaeologically and ethnographically attested numerical notations have been used over the past 5,000 y; however, because most of those systems are no longer used, experimental investigation is challenging. Prior research often assumes, rather than demonstrates, the inferiority of notations like Roman numerals. Gradience is a principle whereby the length of numeral phrases correlates with the magnitude of the numbers being represented. In general, but inconsistently...
