Soil quality is fundamental to nutrient-rich food production and the sustainability of terrestrial ecosystems. However, inappropriate agricultural practices often lead to persistent soil exposure to air and sunlight, which increases soil organic matter losses and erosion risks, particularly under climate extremes. Here, we provide a satellite-based mapping of daily soil exposure occurrence across global croplands from 2001 to 2022 and evaluate the associated degradation risks caused by extreme climate events. We find that while 57% of global croplands experienced a reduction in soil exposure duration in the past two decades, 86% are increasingly subjected to climate extremes. The areas exposed to increasing climate extremes tend to have higher soil organic carbon levels, indicating an intensified degradation risk of global nutrient-rich cropland soils. Our study offers spatio-temporally explicit insights into global cropland soil exposure and its vulnerability to climate extremes, providing evidence to support improvements in sustainable agriculture practices. This paper uses satellite data from 2001 to 2022 to analyze soil exposure in croplands. It shows that while soil exposure duration declined in 57% of croplands, 86% face more climate extremes, threatening soil health.

1 Introduction Narrow-sense heritability is defined as the ratio of additive genetic variance to total phenotypic variance and is interrogated by conventional genome-wide association studies assuming the standard additive genetic model. In contrast, broad-sense heritability is defined as the ratio of total genetic variance to total phenotypic variance, capturing the contribution of non-additive genetics to total phenotypic variance.

Shenzhen, a leading city in China’s Elimination of Mother-to-Child Transmission (EMTCT) Programme, implemented effective practices to reduce HIV-related stigma and officially launched a comprehensive work plan in 2021. This study assessed the trend of HIV-related stigma in Shenzhen’s midwifery hospitals by comparing two surveys of healthcare providers (HCPs) conducted in 2020 and 2023. The study included 2705 HCPs and used an adapted 15-item HIV-related stigma scale. The results showed a significant decrease in stigma, with the mean stigma score dropping from 2.01 in 2020 to 1.89 in 2023. While most items showed improvement, one item related to prejudice and stereotypes showed a slight increase in stigma. In two items on attitudes toward women living with HIV, HCPs were more supportive of their reproductive rights, but less so toward allowing women living with HIV with children to have more. Training was found to be a factor associated with reducing stigma. HCPs who did not receive training, were older, worked as nurses, or had no HIV patient service experience exhibited higher levels of stigma. In general, our findings suggest that the EMTCT programme may contribute to reducing HIV-related stigma, highlighting the importance of continued training and programme optimization to address persistent stigma.

AbstractAlmost all high-grade gliomas, particularly glioblastoma (GBM), are highly migratory and aggressive. Migrasomes are organelles produced by highly migratory cells capable of mediating intercellular communication. Thus, GBM cells may produce migrasomes during migration. However, it remains unclear whether migrasomes can influence GBM migration and invasion. In this study, we observed the presence and formation of migrasomes in GBM cells.
