Astrocytes contribute to autism spectrum disorder (ASD) pathophysiology. Here, the authors show that IP3R2 conditional KO mice show ASD-like behaviours and identify astrocyte-derived ATP as a modulator of these behaviours in mice.

Remote sensing often detects higher vegetation greenness for croplands than for forests, despite forests having a greater leaf area. This study shows that this is an artefact of shadows caused by forest structures and explores how to correct for this when interpreting global vegetation change data.

Single cell transcriptomics can reveal at high resolution the body’s response to infection. Here the authors have applied this technology to a longitudinal SARS-CoV-2 infected cohort and identified gene expression changes that may predict disease severity and reveal the underlying molecular mechanisms.

This paper shows that desertification combating practices decline incomes of farmers and herders, and China needs to adapt its ecological programmes to address the impacts of climate change and create positive synergies to combat desertification.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory respiratory disease characterized by airflow limitation and infective exacerbations. Here, Chan et al. report the generation of nasopharyngeal and bronchial COPD organoids derived from adult stem cells and employ them in the study of host-pathogen interactions, including SARS-CoV-2 and Pseudomonas aeruginosa.

Characterization of full-length genome sequences from patients infected with a new coronavirus (2019-nCoV) shows that the sequences are nearly identical and indicates that the virus is related to a bat coronavirus.
