Wang et al. (Research Articles, 11 December 2020, p. 1295) reported a large decrease in CO2 fertilization effect (CFE) across the globe during the period 1982–2015 and suggested that ecosystem models underestimate the rate of CFE decline. We find that their claims are artifacts of incorrect processing of satellite data and problematic methods for deriving and comparing CFE between satellite data and model simulations.

The article presents the discussion on Jacques Derrida's final major project, focusing on his concept of the 'autobiographical animal.' Topics include extending the notion of autobiography beyond human subjects to include non-human animals, challenging traditional views of life-writing and relationality; and highlighting a shift towards understanding autobiography as a dynamic process across diverse boundaries of existence.

This anonymized Research Note reports qualitative observations and interview evidence to explore the operation of a U-pick lychee orchard located in China’s Pearl River Delta. Observation reveals the ironic juxtaposition of an owner-built cottage on a forested hillside surrounded by an intensively planned, densely populated urban environment featuring high-rise apartment towers. Field data show that informality, social networks, and petty entrepreneurialism are all manifest in urban agriculture, lychee production, labor, and land tenure. This Research Note illustrates the interstitial porosity that exists within the incorporated bounds of an urban area with informal economic activity adjacent to formal occupations and hillside orchards in the shadows of high-rise apartment towers.

This paper focuses on a new model of land readjustment integrated with shareholding in Zhaoqing, China. It determines whether this innovation reduces transaction costs throughout the land development process. To cope with the uncertainty during rapid urbanization in peripheral areas, shareholding land readjustment provides opportunities for the original landowners to share the long-term sustainable land value increment. This is accomplished through a shareholding platform built by local government and a closely associated state-owned enterprise, with a guarantee of short-term fixed compensation. Shareholding land readjustment holds great promise in connecting plan implementation with land property exchange issues in the Global South. [ABSTRACT FROM AUTHOR]

Ebolaviruses and marburgviruses belong to the family Filoviridae and cause high lethality in infected patients. There are currently no licensed filovirus vaccines or antiviral therapies. The development of broad-spectrum therapies against members of the Marburgvirus genus, including Marburg virus (MARV) and Ravn virus (RAVV), is difficult because of substantial sequence variability. RNAi therapeutics offer a potential solution, as identification of conserved target nucleotide sequences may confer activity across marburgvirus variants. Here, we assessed the therapeutic efficacy of lipid nanoparticle (LNP) delivery of a single nucleoprotein-targeting (NP-targeting) siRNA in nonhuman primates at advanced stages of MARV or RAVV disease to mimic cases in which patients begin treatment for fulminant disease. Sixteen rhesus monkeys were lethally infected with MARV or RAVV and treated with NP siRNA-LNP, with MARV-infected animals beginning treatment four or five days after infection and RAVV-infected animals starting treatment three or six days after infection. While all untreated animals succumbed to disease, NP siRNA-LNP treatment conferred 100% survival of RAVV-infected macaques, even when treatment began just 1 day prior to the death of the control animals. In MARV-infected animals, day-4 treatment initiation resulted in 100% survival, and day-5 treatment resulted in 50% survival. These results identify a single siRNA therapeutic that provides broad-spectrum protection against both MARV and RAVV., Introduction From 1967 until late 2013, members of the 2 genera of filoviruses, Marburgvirus and Ebolavirus, have caused periodic occurrences of hemorrhagic fever (HF) in Central Africa, resulting in severe [...]
