Global warming caused by carbon emissions has become a significant concern for countries worldwide. This study thoroughly examines the spatiotemporal patterns and spatial spillover effects of carbon emissions in China. This research employs kernel density estimation, Moran's index, and the standard deviation ellipse model to analyse the spatiotemporal evolution of carbon emissions in China while utilizing the spatial Durbin model to explore the spatial spillover effects of the digital economy on carbon emissions.

Article Synopsis
- The COVID-19 pandemic disrupted food systems, revealing vulnerabilities but also offering opportunities to build more resilient and sustainable food practices.
- A study conducted in Madrid analyzed changes in consumer habits during lockdowns through surveys, highlighting variations based on age, gender, income, and education.
- Findings indicated a notable shift towards local and organic product consumption and increased online shopping, with alternative food networks contributing to improved food security, regardless of urban or rural distinctions.
Focal adhesions, reticular adhesions, flat clathrin lattices: what divides them, what unites them?

Article Synopsis
- Most cells in multicellular organisms need to attach to their environment, using structures called cell-matrix or cell-cell adhesions for stability.
- Integrins are key transmembrane receptors that help form these adhesion complexes by connecting with extracellular matrix components and linking to the cell's cytoskeleton, allowing for signaling.
- Recent research reveals that different types of integrin complexes, once thought to be separate, are actually interconnected and can influence each other's formation and transformation, particularly focusing on the versatile αvß5 integrins.
Machine learning based on event-related oscillations of working memory differentiates between preclinical Alzheimer's disease and normal aging.

Objective: To apply machine learning approaches on EEG event-related oscillations (ERO) to discriminate preclinical Alzheimer's disease (AD) from age- and sex-matched controls.
Methods: Twenty-two cognitively normal preclinical AD participants with elevated amyloid and 21 cognitively normal controls without elevated amyloid completed n-back working memory tasks (n = 0, 1, 2). The absolute and relative power of ERO was extracted using the discrete wavelet transform in the delta, theta, alpha, and beta bands.

Metal-organic frameworks (MOFs) are a class of materials composed of coordinative interactions between metal ions and organic linkers, encompassing two-dimensional (2D), and three-dimensional (3D) architectures. Metal-organic cages (MOCs), a special case of these species, are discrete molecular "capsules" with zero-dimensional (0D) structures. Over the last two decades, MOFs and MOCs composed of organic perylene (P) and perylene diimide (PDI) linkers have gained much attention due to their versatile properties, which can be further enhanced after incorporation into frameworks.
