State Key Laboratory of Vegetation and Environmental Change, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China.

Climate warming may induce substantial changes in the ecosystem carbon cycle, particularly for those climate-sensitive regions, such as alpine grasslands on the Tibetan Plateau. By synthesizing findings from warming experiments, this review elucidates the mechanisms underlying the impacts of experimental warming on carbon cycle dynamics within these ecosystems. Generally, alterations in vegetation structure and prolonged growing season favor strategies for enhanced ecosystem carbon sequestration under warming conditions.

Interorgan lipid transport is crucial for organism development and the maintenance of physiological function. Here, we demonstrate that long-chain acyl-CoA synthetase (dAcsl), which catalyzes the conversion of fatty acids into acyl-coenzyme As (acyl-CoAs), plays a critical role in regulating systemic lipid homeostasis. dAcsl deficiency in the fat body led to the ectopic accumulation of neutral lipids in the gut, along with significantly reduced lipoprotein contents in both the fat body and hemolymph.

Dyslipidemia affects approximately half of all people with gout, and prior Mendelian randomization analysis suggested a causal role for elevated triglycerides in hyperuricemia (HU), but the underlying mechanisms remain elusive. We hypothesize that dyslipidemia promotes hepatic urate biosynthesis in HU and gout and fatty acid (FA) oxidation (FAO) drives this process. Here we developed a targeted metabolomics to quantify major metabolites in purine metabolic pathway in the sera of a human cohort with HU, gout, and normaluricemic controls.

Potential therapeutic strategies for MASH: from preclinical to clinical development.

Life Metab

October 2024

State Key Laboratory of Drug Research, Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai 201203, China.

Current treatment paradigms for metabolic dysfunction-associated steatohepatitis (MASH) are based primarily on dietary restrictions and the use of existing drugs, including anti-diabetic and anti-obesity medications. Given the limited number of approved drugs specifically for MASH, recent efforts have focused on promising strategies that specifically target hepatic lipid metabolism, inflammation, fibrosis, or a combination of these processes. In this review, we examined the pathophysiology underlying the development of MASH in relation to recent advances in effective MASH therapy.

Nonnegligible cascading impacts of global urban expansion on net primary productivity.

PNAS Nexus

January 2025

Key Laboratory of Geographic Information Science (Ministry of Education), School of Geographic Sciences, East China Normal University, Shanghai 200241, China.

Accelerated global urban expansion not only directly occupies surrounding ecosystems, but also induces cascading losses of natural vegetation elsewhere through cropland displacement. Yet, how such effects alter the net primary productivity (NPP) worldwide remains unclear. Here, we quantified the direct and cascading impacts of global urban expansion on terrestrial NPP from 1992 to 2020 and projected the impacts under the shared socioeconomic pathways framework by 2100.

Key Laboratory of Mountain Surface Processes and Ecological Regulation, Institute of Mountain Hazards and Environment, Chinese Academy of Sciences, Chengdu, People's Republic of China.

Conservation agriculture, which involves minimal soil disturbance, permanent soil cover, and crop rotation, has been widely adopted as a sustainable agricultural practice globally. However, the effects of conservation agriculture practices on soil NO emissions and crop yield vary based on geography, management methods, and the duration of implementation, which has hindered its widespread scientific application. In this study, we assessed the impacts of no-tillage (NT), both individually and in combination with other conservation agriculture principles, on soil NO emissions and crop yields worldwide, based on 1270 observations from 86 peer-reviewed articles.

State Key Laboratory of Structural Chemistry, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Fuzhou, Fujian, 350002, China.

Organic-inorganic hybrid perovskites (OIHPs) have shown great potential for direct X-ray detection in security screening and medical diagnostics. However, their humidity stability is compromised due to the susceptibility of the structural components to water molecules, thereby limiting their practical application. In this work, stable and sensitive X-ray detection is achieved using high-quality bulk single crystals of the 3D perovskitoid (DMPZ)PbBr (DPB, DMPZ = N,N'-dimethyl-pyrazinium), wherein N-acid protons are replaced with hydrophobic alkyl groups.

Twisted bilayer graphene (TBG) has drawn considerable attention due to its angle-dependent electrical, optical, and mechanical properties, yet preparing and identifying samples at specific angles on a large scale remains challenging and labor-intensive. Here, a data-driven strategy that leverages Raman spectroscopy is proposed in combination with deep learning to rapidly and non-destructively decode and predict the twist angle of TBG across the full angular range. By processing high-dimensional Raman data, the deep learning model extracts hidden information to achieve precise twist angle identification.

Duration adaptation depends on the perceived rather than physical duration and can be observed across sensory modalities.

Perception

State Key Laboratory of Brain and Cognitive Science, Institute of Biophysics, Chinese Academy of Sciences, China; University of Chinese Academy of Sciences, China; Hefei Comprehensive National Science Center, Institute of Artificial Intelligence, China.

Previous research has indicated that exposure to sensory stimuli of short or long durations influences the perceived duration of subsequent stimuli within the same modality. However, it remains unclear whether this adaptation is driven by the stimulus physical duration or by the perceived duration. We hypothesized that the absence of cross-modal duration adaptation observed in earlier studies was due to the mismatched perceived durations of adapting stimuli.

To uncover these layers of information, a solvatochromic and photosensitized LDs-targeted probe based on the furan-based D-D-π-A scaffold is developed to offer the following integrated functions. First, the turn-on fluorescence of the probe upon selectively binding to LDs allows for direct visualization of their location and morphology.

Drug delivery for epilepsy treatment faces enormous challenges, where the sole focus on enhancing the ability of drugs to penetrate the blood-brain barrier (BBB) through ligand modification is insufficient because of the absence of seizure-specific drug accumulation. In this study, an amphipathic drug carrier with a glucose transporter (GLUT)-targeting capability was synthesised by conjugating 2-deoxy-2-amino-D-glucose (2-DG) to the model carrier DSPE-PEG. A 2-DG-modified nano drug delivery system (NDDS) possessing robust stability and favourable biocompatibility was then fabricated using the nanoprecipitation method.

Polymers of intrinsic microporosity (PIMs) are an emerging class of amorphous organic porous materials with solution processability, which are widely used in a multitude of fields such as gas separation, ion conduction, nanofiltration, etc. PIMs have adjustable pore structure and functional pore wall, so it can achieve selective sieving for specific substances. In order to meet the functional requirements of PIMs, two principal methods are used to synthesize functional PIMs, namely, post-modification of PIMs precursors and functionalization of monomers.
