Cellular automata (CA) models like SLEUTH (an acronym for slope, land use, excluded area, urban extent, transport-network and hill shade) have predominantly been developed and applied in developed countries. Modeling can serve as a tool to guide policy measures in facing urbanization challenges. However, developing cities have peculiar differences (heterogeneity, poor planning, and low infrastructure) thus the existing modeling approaches may not be able to apprehend heterogeneous urban growth.

Northwest China has abundant solar energy resources and extensive land, making it a pivotal site for solar energy development. However, restrictions on site selection and severe weather conditions have hindered the establishment and operation of photovoltaic (PV) power stations. Previous studies have not considered meteorological factors when evaluating site suitability, leading to research gaps in identifying suitable areas and establishing indicator systems.

Desertification constitutes a grave threat to the environmental and socio-economic stability of desertification frontline states in Northern Nigeria. From 2003 to 2020, this research comprehensively analyzes desertification vulnerability, integrating parameters such as NDVI, LST, TVDI, MSAVI, and Albedo. Key factors contributing to land degradation are identified, along with the spatial patterns and trends of desertification over the two-decade period.

Article Synopsis
  • - Land-use change significantly contributes to biodiversity loss in Africa, yet there has been limited research on future projections due to uncertainties; this study aims to fill that gap by analyzing various land-use scenarios from 2021 to 2100.
  • - The research uses 2020 observational land-use data to evaluate future changes across seven Shared Socioeconomic Pathways (SSP) scenarios, finding strong correlations (0.89) between current and projected land uses.
  • - Projected outcomes indicate a decrease in barren and forest land, while cropland, grassland, and urban areas will likely expand significantly, raising concerns about biodiversity loss and ecosystem health in the region.

Article Synopsis
  • The study looks at how human activities affect the plants and environment in the Niger River Basin between 2000 and 2020.
  • It used satellite images to analyze changes and found that most of the area (about 89.88%) was negatively impacted by these activities.
  • The researchers suggest using better methods to help fix the environment, like better farming practices and protecting natural resources.

Gene expression is the synthesis of proteins from the information encoded on DNA. One of the two main steps of gene expression is the translation of messenger RNA (mRNA) into polypeptide sequences of amino acids. Here, by taking into account mRNA degradation, we model the motion of ribosomes along mRNA with a ballistic model where particles advance along a filament without excluded volume interactions.

An ethnobotanical study was conducted in Comores (Ngazidja) about plant species used traditionally for the treatment of various diseases, including malaria. Antimalarial activity of 76 vegetal extracts obtained from 17 species traditionally used to treat malaria symptoms, was evaluated in vitro using Plasmodium falciparum chloroquine-resistant strain (W2). Antiproliferative activity was evaluated on human monocytic THP1 cells and the selectivity index of the plant extracts was calculated.
