Summary: There have been five Mass Extinction events in the history of Earth's biodiversity, and the Sixth Mass Extinction may currently be occurring due to human activities. While some dispute the existence of the Sixth Mass Extinction, arguing that the rate of species loss is not significantly different from background rates, this viewpoint is flawed due to the bias of the IUCN Red List. Incorporating estimates of invertebrate extinctions suggests that the current rate of extinction far surpasses background rates, pointing to the start of the Sixth Mass Extinction.

Summary: SARS-CoV-2 infection can lead to severe symptoms and long-lasting lung damage or death. This is often associated with high levels of pro-inflammatory cytokines and low antiviral responses. A specific activation of NF-kappa B and block of IRF3 nuclear translocation were observed in infected cells. The inflammatory response is mediated by cGAS-STING activation and can be attenuated through STING-targeting drugs.

Summary: We propose a novel and non-discriminatory classification method for monkeypox virus diversity. Collaborating with the World Health Organization, we named three clades (I, IIa, and IIb) in the order of detection. Within IIb, which is responsible for the ongoing global outbreak, we identified multiple lineages (A.1, A.2, A.1.1, and B.1) to support real-time genomic surveillance.

Summary: COVID-19 is spreading globally, and the diagnosis is usually based on examining chest radiographs. Manual processing of the images is not efficient and accurate enough. To improve the efficiency, this research proposes a multilevel thresholding image segmentation method based on an enhanced multiverse optimizer. The method achieves better segmentation results and can help medical organizations process COVID-19 chest radiography effectively.

Summary: AI is increasingly used in clinical applications for diagnosis and treatment decisions, with deep neural networks showing equal or better performance than clinicians. However, their lack of interpretability calls for the development of methods to ensure their trustworthiness. Nine different types of interpretability methods have been identified for understanding deep learning models in medical image analysis, with ongoing research on improving interpretability and evaluation methods for deep neural networks.

Summary: This study used single-cell RNA sequencing analysis to identify macrophages as potentially associated with SARS-CoV-2 lung pathogenesis and ribosome-related pathways as potential therapeutic targets for COVID-19 lung infection. M1-like macrophages showed a strong relationship with severe COVID-19 patients, with upregulation of chemokine pathways leading to severe symptoms and down-regulation of ribosome and RNA activity pathways potentially leading to milder cases. Additionally, analysis of organ-specific susceptible cell types could provide further targets for COVID-19 therapy.
